Second, the main practices

(A) unity of thought, strengthen confidence

Since the construction of 1 xx highway, it has been highly valued by governments at all levels, provincial and municipal leaders and relevant departments, and has given strong support in industry management and policies. Local governments at all levels along the line attached great importance to it and implemented on-site supervision by special personnel, which ensured the external environment of construction, realized the orderly progress of project construction and effectively enhanced our confidence and determination to build a good project.

2. In order to promote the follow-up of all work, the director's office insists on holding a weekly regular meeting once a week to inform the work completion, arrange weekly work tasks, strengthen information communication and feedback, and ensure the unity of thinking, understanding, pace and action.

(2) Careful organization and scientific scheduling.

1, according to the requirements of the construction period, the remaining quantities will be reversed and implemented in stages according to the ten-day, monthly, quarterly, half-year and total construction period, and the project construction will be promoted in a coordinated, orderly and steady manner. The director's office shall formulate detailed and reasonable construction organization plans according to the target requirements, urge all construction units to formulate work plans every ten days, months and seasons according to the overall target, and then determine the personnel and equipment invested according to the construction plan. The Office of High Supervision will check the implementation of the plan once a week, and the resident supervisor will check the implementation of the plan once a day, and take measures to remedy the unfinished tasks to ensure the implementation of the task plan every day.

2, to further strengthen the construction organization and management, strengthen the construction scheduling work, not started part of the construction, has started part of the completion, to ensure that there is no construction gap.

3, constantly according to the actual engineering construction and quarterly work objectives, strengthen the safeguard measures, the implementation of personnel, machinery and equipment investment, do everything possible to organize the material supply, do not stop work, to ensure the normal construction of pile, column, beam slab prefabrication.

4, scientific organization, crossover operation, in the first phase of subgrade construction at the same time, pay close attention to the second phase of the road construction unit bidding, approach, the third phase of housing construction, electromechanical, traffic safety, greening and other projects bidding preparation.

5. According to the annual overall construction goal, the "Hundred Days War" labor competition will be held from March 2/KLOC-0 to June 30, the "Bimonthly Competition" will be held from August/KLOC-0 to September 30, and the "Four Seasons War" will be held on June 1 0.

Through the "Hundred Days Battle" labor competition with the theme of "controlling projects, ensuring progress, standardizing management, ensuring quality, civilized construction and ensuring safety", the total output value of the whole line was # billion yuan, which greatly mobilized the enthusiasm of the contractor, initially formed large-scale production and achieved the goal of the first battle.

Through the development of "learning tenacity, standardizing management, creating quality projects; The "bimonthly competition" with the theme of "Honest performance, civilized construction to ensure work objectives" ensured the basic completion of the stage objectives. All units seized the golden construction season of autumn and winter, increased investment in personnel and machinery, and set off a climax of engineering construction. The machinery on the construction site works 24 hours a day, and people stop working. Production personnel race against time, working overtime in sunny and rainy days, continuously. The bimonthly competition realized an output value of 1, 200 million yuan.

(3) Grasp the key points and overcome the difficulties.

1. In the work, we always insist on highlighting key points and paying special attention to key road sections, which has promoted the rapid progress of the project from point to surface. In the general layout, the Jiangtan Bridge, Junshan Interchange, Shamao Interchange and Spillway Interchange are emphasized, and special attention is paid to soft foundation treatment, bridge substructure, small structure, earthwork and beam slab prefabrication in the process.

2. With the key "helping" method, the leaders of the head office are invited to the construction site for rectification for the bid sections with relatively lagging construction quality and progress, and the director's office confirms counterpart support. With the careful organization and continuous efforts of the construction unit, the situation of these blocks has obviously improved in a short time.

(4) Strengthen management to realize high-quality and safe construction.

1. In terms of engineering quality, implement the requirements of the outline of excellent highway construction in Hubei Province, adhere to the policy of "quality first in a hundred years" and adhere to the quality work policy of "excellent internal quality and beautiful external quality". Constantly improve the quality system, first, improve the contractor's self-inspection and inspection system, strengthen the special class inspection in the construction of each working procedure, implement self-inspection after each working procedure is completed, and declare the construction of the next working procedure to the supervision engineer after passing the inspection; The second is to improve the internal supervision and control system. The station is responsible for supervising the work performance and performance of supervisors, assessing the performance of supervisors through physical quality inspection, and regulating and restraining the work behavior of supervisors through inspection. Master the control of raw materials, processes and working procedures. Strengthen the control of raw materials to ensure the quality of cement, steel, gravel, bearings, anchors, etc. Strict construction technology requirements, focusing on mixture ratio, concrete curing, etc. , grasp the weak links, such as the strength, maintenance and appearance of T-beams and small structures; Implement strict process verification system, clarify responsibilities and strengthen process management. Unqualified projects will never be soft, and measures such as shutdown, rectification and rework will be taken to ensure the quality of the project. Master the work quality of supervision and outsourcing inspection units, ensure that the supervision always controls the project quality at multiple levels, strengthen the supervision work on holidays and nights, strive to eliminate the weak links in supervision work and do a good job in quality control.

2. Seriously implement the policy of "safety first, prevention first", strictly manage the site and pay close attention to the implementation of measures to ensure that no major accidents occur. First, a leading group for production safety was set up, a special safety management organization was set up, and full-time safety management personnel were equipped to ensure that the safety work covered the whole project and all links as a whole. Second, adhere to both safety education and safety precautions, adhere to the system of combining regular and irregular inspections on the construction site, find hidden dangers in time, and make timely rectification.

(V) Strengthen coordination services and promote the smooth progress of project construction.

1, strengthen the coordination service of land requisition and demolition, do a good job of demolition finishing and three-pole relocation, assist in temporary land use and ensure earthwork construction.

2, seriously deal with engineering construction and local problems, timely recovery of farmland water system, timely recovery of field tractor roads, strengthen field road maintenance and watering, etc. To avoid incidents that harm farmers' interests.

3. Accelerate the measurement and payment, actively organize audit, construction and supervision units, and carefully review the unit price changes; Intervene in data sorting and auditing in advance to shorten the measurement time and ensure the supply of funds; Measures were taken to change one-time measurement into multiple measurement, that is, the project was completed at one time, and then all relevant information was complete, thus alleviating the financial pressure.

4. Actively coordinate the supply of raw materials, actively contact with cement plants and steel mills, and take the strength of the owner as a guarantee to ensure the supply of engineering materials and the smooth progress of construction.

(6) Give full play to the enthusiasm of the construction unit to ensure the smooth progress of the project.

All construction units actively take various measures, do everything possible to overcome difficulties and go all out to speed up the project construction. For example, in the construction of the main pier of 1 contract section # bridge, the equipment investment was increased, two prefabricated yards were set up, and the steel structure temporary bridge was built, so that the main pier was fully discharged before the rainy season, which ensured the development of subsequent projects. 2 The earthwork construction in this contract section actively seeks the soil source, which ensures the normal construction of subgrade and the comprehensive construction of structures. In the face of difficulties, the contract section did everything possible to ensure the smooth progress of the project construction, explained the difficulties and problems to superiors and employees, strived to win the support of all parties, dealt with the serious shortage of liquidity in time, and ensured the construction of key control projects such as steel box beams. During the Spring Festival, all the staff of the project department in the contract section will give up reunion with their families and stick to their posts. The team members are on duty at the construction site in turn 24 hours a day. When the liquidity is seriously insufficient, actively raise funds by itself to ensure the wages of migrant workers and the cost of purchasing materials, and prepare various construction materials before the Spring Festival.

(seven) to strengthen the construction of a clean government, to protect the engineering construction.

Earnestly strengthen the construction of a clean government, carry out the publicity and education of "six prohibitions", timely convey the spirit and documents of various meetings, constantly raise awareness of the importance of building a clean government through the education of clean government, strive to build a defense line against corruption and change, enhance the self-discipline awareness of contractors, and make unremitting efforts.

Three, XX years of work ideas

Xx year is a crucial year for the construction of XX expressway to go hand in hand and advance as a whole, and it is also a crucial year to ensure the realization of the # # construction goal put forward by the provincial party committee, the provincial government, the municipal party committee and the municipal government. We will closely focus on this overall goal, formulate practical and effective measures, strengthen refined management, fully mobilize the enthusiasm of all participants, and make unremitting efforts to achieve the construction goal.

(1) Work objective

It is planned to complete the investment of xx billion yuan in xx years.

The first phase of the project has been completed. The second phase of pavement base started in # month, and the pavement surface started in # month. The house building project was completed. Complete the bidding for electromechanical, greening and traffic safety projects before the end of # year #.

(B) working ideas and measures

1, according to the annual target requirements of # year, formulate detailed and reasonable annual, quarterly and monthly construction organization plans, scientifically organize the construction of Phase I, Phase II and Phase III projects, cross-operate, and reverse the construction period, decompose and implement them one by one according to the time period and bid section, urge the construction unit to increase investment, increase engineering and technical personnel, increase mechanical equipment, and fully mobilize the enthusiasm of the construction unit to speed up the project construction.

2. Further improve the quality assurance system, establish a firm sense of quality first, and follow the four-level quality assurance system of enterprise self-inspection, supervision sampling inspection, owner inspection and quality supervision station supervision. The technical disclosure of construction shall be implemented to each team and each construction worker, and the construction shall be carried out in strict accordance with the relevant specifications, standards and the process and quality requirements of construction drawing design.

3. Continue to do the important and difficult work, pay close attention to the construction of earthwork, T-shaped structure, beam slab prefabrication, steel box beam, continuous beam and underwater structure in the first phase, and organize the mobilization construction in the second and third phases.

4. In strict accordance with the relevant provisions of the contract, tender documents, etc., urge the contractor to perform the project contract to prevent the construction unit from affecting the progress and quality of the project due to lack of personnel, equipment and technical strength. For units that are seriously behind schedule, it is necessary to meet with bidders, strictly evaluate rewards and punishments, and take a multi-pronged approach to ensure the smooth implementation of the project plan. Encourage contractors to take active measures to speed up the progress on the basis of ensuring quality through material and spiritual rewards; For acts that do not meet the requirements of contract documents and specifications, material penalties will be strictly imposed to ensure the quality of engineering construction.

5. Strengthen supervision and management. In view of the fact that the first, second and third phases of the project are carried out at the same time, and the construction period is increasing, urge the high supervision office to increase the investment of supervision personnel to ensure the efficiency and quality of supervision work; The key process must be on the sidelines all the time, and the high supervision office is required to ensure that one person takes more than one person to inspect the site every day; In accordance with the requirements of supervision specifications, strictly manage and conscientiously implement various supervision systems to ensure the quality, efficiency, safety and reliability of the project; Pay attention to improving the quality of supervisors, actively organize supervision training, and insist on replacing incompetent personnel.

6. Strengthen internal management and improve internal management efficiency.

With the spread of the first, second and third phases of the project, the management pressure of the director's office has increased unprecedentedly, which is a severe test for the comprehensive management ability of the whole project management system. To this end, we will strengthen internal management, strict internal discipline and management system, so that orders are prohibited; Improve working methods, improve work efficiency, assign special personnel to supervise the progress of each bid section, organize joint office on site in time, hold site meetings, etc. Solve the problems in the project; Strengthen the coordination of relocation, survey and engineering technology to create a good environment for the construction unit.

Second, the highway engineering work summary model essay

I am xxxx, male, born on September 28th, xxxx. I graduated from xxX Transportation Vocational and Technical College in XX, and received a national grant in xxxX. I was engaged in engineering construction survey, engineering supervision and laboratory work in Chitong expressway and Chitong expressway in XX, and I have been engaged in highway and bridge engineering technology since XX. Through nearly four years of practical work, some achievements have been made. The following is a summary of the professional and technical work of the review body.

First, rich knowledge is the prerequisite for professional and technical work.

Since joining the work in xxx years, I have been engaged in professional work related to highway bridge construction and highway engineering. In XX, he was admitted to xxx Vocational and Technical College of Communications, majoring in highway engineering and management. After three years of study, I have accumulated rich professional theoretical knowledge. Obtained the certificate of laboratory technician in xxx years. Engaged in highway maintenance, highway bridge construction, engineering technology management, construction survey, engineering supervision and laboratory work in Chitong expressway and Chitong expressway successively, participated in cement concrete pavement damage repair project, served as technical director, surveyed the second-class highway from Yangshuwan to Fengzhen section of s 102 line, improved the pavement of s208 second-class highway, served as technical director during this period, and also participated in the scientific research project of Wulanchabu Highway Engineering Office-Yi. As the technical director of the project.

Second, be brave in innovation and sum up experience. The level of professional and technical work has been gradually improved in practice.

I participated in the pavement reconstruction project of xxxx secondary highway in XX, and served as the technical director in this project, which played a good role in the mechanized construction of cement stabilized gravel, such as mechanical equipment, material consumption and control, technological process and engineering quality control. This paper summarizes the treatment methods and key points of frost on asphalt pavement in spring. When there is too much rain in spring, which is not conducive to the traffic of asphalt pavement, three main treatment measures are taken: (1) open trench is dug on the shoulder: a horizontal open trench is dug every 6-8 on the shoulders on both sides of the frosty section in early spring. Drain the water in time and remove the moisture on the road surface. (2) Dig an open trench on the cross section or subgrade to avoid water accumulation on the pavement. (3) Dig a seepage pit. Dig a pit with a diameter of about 20-40cm in the section that is easy to boil, and manually take out the pit water at regular intervals. In recent years, the main types of engineering water damage are subgrade subsidence, subgrade collapse, bridge damage, protection and reinforcement engineering damage. Highway water damage should focus on prevention, eliminate hidden dangers of water damage in time, and nip in the bud. As long as we pay attention to water damage from the aspects of highway design, construction and maintenance, and take corresponding measures, the water damage of highway will be effectively controlled.

Three, the courage to explore, integrate theory with practice, and make remarkable achievements in professional and technical work.

Xxxx year 10 month, as a technician of cement road maintenance engineering team. In the mileage of xx County Highway Administration Bureau, the second-class cement concrete pavement of national highway is 49 kilometers, and the public stone line of provincial highway is 49 kilometers and 5 kilometers. In order to make the traffic comfortable, I found an economical and reasonable method to repair the broken slab of cement concrete pavement. Through practical observation, I found that the main reason for the broken slab is the instability of the grassroots, and the main factor affecting the instability of the grassroots is the infiltration of rainwater into the grassroots. Under the action of load, the base began to deform and the mud was pumped out. In view of this phenomenon, we proposed to the municipal maintenance department to strengthen the joint maintenance of cement concrete pavement, and adopted scientific joint maintenance and high-density joint maintenance materials, which played an obvious role in curbing the damage of cement concrete pavement and was praised by the leaders of the municipal bureau.

The I-beam of Heigoudang Bridge on xxxx National Road is displaced, the deck pavement is broken, and the bridge expansion joint is damaged. It has been identified as a dangerous bridge by provincial and municipal experts and needs reinforcement and maintenance. I am the technical director of this project. In view of various diseases of the bridge, after nearly ten days' observation, simply supported beams are used to stabilize the I-beams and reinforce them again for deck pavement. After more than four months of maintenance and reinforcement, it was tested as a qualified and high-quality project by provinces and cities, which greatly improved the traffic capacity of the bridge and ensured the driving safety. The project was well received by provincial and municipal leaders, and the municipal highway maintenance department held a site meeting of the city's bridge maintenance and reinforcement project here, which personally encouraged me. In April of xx, the construction task of bid J of the secondary pavement improvement project of XX National Road was completed. I am the technical director, laying gravel foundation on the basis of the old oil pipeline. During the construction, it was found that the old oil road surface was massive and extremely unstable, so it was reported to the municipal bureau. After on-the-spot investigation, I suggest digging out the loose oil foundation and taking measures on the spot to make up for it. Through deflection detection, all technical indicators are qualified, and the project is rated as high-quality project. In 2000 10, he served as the technical director of Liusha wiring reconstruction project. When treating soft foundation, k00+300-k00+500 has 200m soft foundation, which cannot be treated. Because there is a pool next to the subgrade, combined with the knowledge learned from books, the lime pile was treated, and then the concrete foundation with the bottom mark was constructed. After three days, the allowable value is completely within the standard range.

In August of xxxx, he participated in the pilot project construction of Jining Road Project and served as technical director of xxx. Because xx line is the main trunk line connecting xx national highway in our city, it plays a very important role in the economic development of our city. According to the requirements of the scientific research project of xx Provincial Highway Bureau, its main purpose is to compare the service life of various overlay layers with different structures on the old cement concrete pavement under the same natural conditions such as climate, hydrology and geology and the same traffic volume, and to find a typical example of overlay reconstruction of the old cement concrete pavement which is suitable for the actual situation in the west, feasible in technology, reasonable in economy and convenient in construction. Under the leadership of the Municipal Highway Bureau and the competent department, I participated in various bearing capacity tests and cbr value detection in the project technology department, and measured the deflection of different parts of the plate. Participated in the initial survey, design to actual construction lofting, leveling point recovery and midline determination, providing first-hand digital basis for it. At the experience exchange meeting, it was well received by the leaders, and the project was initially evaluated as a high-quality project.

Four, strict standards, strict requirements, and strive to make professional and technical work to a new level.

Since I have been engaged in highway engineering and technology in xxxx, I have been strict with myself and applied my theoretical knowledge to the construction of large and medium-sized highways, which has achieved certain practice and good social and economic benefits. Construction shall be carried out in strict accordance with Technical Standards for Highway Engineering and Standards for Inspection and Evaluation of Engineering Quality. As a qualified technical director, I strictly manage the project quality, control the project cost, be the assistant of the project manager, dare to innovate and explore in technology and sum up practical experience. During my years as a technician, I performed my technical duties well and was praised by the leaders of my work unit many times.

In recent years, we have done a lot of work for the society and the highway industry. In order to adapt the professional technical level and professional technical working ability to the development of highway, we need to continue to learn professional technical knowledge, sum up experience, enrich our professional theoretical level and practical construction ability, push professional technical posts to a new level, and do our part for the development of highway construction.

Three, highway engineering work summary essay

Since I graduated as a technician, I have been mainly engaged in the management, study and practical operation of surveying engineering, and worked as a bridge manager and assistant technician of surveying engineering in Pingding expressway Project Department. After that, he was responsible for the measurement and data collation of Leilizhixing water supply project in Jiayuguan, Fuzhou. At present, he is responsible for the measurement work in the project department of Zhongyan Gansu Wuyang Salt Chemical Co., Ltd. and concurrently serves as the deputy secretary-general of the Association for Science and Technology. Over the past few years, based on my post, I have devoted myself to work. According to the new requirements of engineering survey under the new situation, I have focused on the engineering survey system and experience, and strived to achieve more accurate and professional survey work.

Engineering survey is an important procedure of engineering construction and an important link of engineering quality control and testing. In order to strengthen the management of engineering survey, unify the relevant systems of engineering survey, and better provide guarantee for creating high-quality projects and striving for the best results.

A, the construction unit after receiving the pile point, survey workers need to protect the pile point and review. If encryption is needed, carefully survey the terrain and select points. Choose a good place that is firm and not easy to be damaged during construction as the encryption point.

Second, when the design institute drawings are reviewed in place, the main task of the surveyors is to review the drawings. There are many mistakes in drawing according to experience. These hidden dangers will bring serious consequences to the project if the side construction is not carefully examined. Although this is the responsibility of design, we can't escape the responsibility. When reviewing drawings, we must master the changes in combination with other relevant drawings, among which checking the top elevation of pile foundation is the key point.

3. Cast-in-place pile construction is the key to the bridge alignment, and it is listed as the full inspection project of the supervisor, providing reference for the position of the pier of the bearing platform in the future. When calculating the data of cast-in-place pile, we should pay attention to whether there is linear deviation. In addition, when calculating the data of cast-in-place pile of abutment, we should carefully check whether the expansion joint of abutment is consistent with the center line of abutment. If the column position is lost, the reasons should be explained and a punishment system should be established for the owner. Because temporary landfill is very dangerous.

Four, after the pile cap reinforcement molding, to strictly control the normal direction of reinforcement. If there is a deviation between the center of the line and the center line of the pier, we should attach great importance to coordination. The central coordinates and normal azimuth data of the pier should be calculated by table indoors, and the numerical units of deviation should be unified. Temporary control points of pier reinforcement crosshairs shall be firm and clearly marked, and shall be handed over to the person in charge of next working procedure before leaving.

Five, the pier top elevation and leveling control is the key step of bridge engineering, before the pier molding pouring, should be at least twice to measure the nuclear effect of the level of the column top elevation, and steel ruler to measure whether the distance between the column top and the cap top is consistent with the design, other column top elevation measurement, such as steel bar surface marking should be clear and standardized, below the datum.

6. The construction of box girder is the most important part and key point in bridge construction. The measured data in box girder construction are mainly the edge of box girder bottom plate, the inner edge of collision wall and the box girder ground. Wing plate, top surface elevation. It is required that the sideline and elevation data must be calculated by two people. In the calculation process, special attention should be paid to whether the center line of box girder structure coincides with the center line of design line.

Seven, surveying engineering field work is important, but the indoor work is more important, and the indoor data should be neat, clear and clear. In our work, mastering the flexible data of drawings for the first time should be a deeper and clearer performance for our work.

As qualified surveyors, they must deal with various projects, use different measuring methods, find out the measuring points of different projects, and ensure the normal operation of project progress and quality. It is our fine tradition to make full use of computer software to calculate and manage data, input effective data into the computer and form data check. It is our fine tradition that a single person cannot complete the measurement task. In addition, consolidate the basic knowledge and strengthen the correct operation skills.

Engineering survey is the premise and basic work of engineering entity construction in building construction. The content of engineering survey is to measure the positions of buildings and structures designed on the general construction plan to the construction site according to the design requirements, and locate them correctly on the ground.

The development of engineering technology constantly puts forward new requirements for surveying, especially the development of global positioning system (GPS), geographic information system (GIS), photogrammetry and remote sensing (RS), digital mapping and ground surveying technology, which makes the means, theories and methods of engineering surveying have undergone profound changes.

(1) Basis for measuring and setting out before excavation: The plan drawn by the design institute provided by Party A and the planning permit approved by the Planning Bureau must be available. Notice of pile position coordinate results provided by Surveying and Mapping Institute. Only the construction party and the supervision party can set out and check the line.

(2) The construction party's measuring unreeling inspection sheet and engineering positioning measurement memory record must be signed and agreed by the supervisor.

(3) The construction party can start excavation only after the supervisor has inspected the line. Pay attention to measuring the angle with theodolite and drawing the distance with steel ruler. In order to prevent errors, it is best to retest the results by diagonal method. The location of temporary BM point on site shall be reflected in the engineering calibration test record. At the same time, BM point should be visible, firm and not easy to destroy, and clearly marked.

(4) Pay attention to the line inspection of foundation pit, and the construction unit can only start paying-off after the cushion and fireproof layer are finished. In addition to the outline, the inner wall, beam and column of the bottom ring, post-cast strip and thin part of elevator shaft shall be released. This line must be carefully checked, otherwise it will cause dislocation and missing reinforcement. After the control network or main axis is determined, protective measures shall be taken for the pile immediately. On general land, (200mm*200mm* 100mm) piles can be driven on the road surface with nail gun, and the top surface of the piles is covered with (200mm*200mm*3mm) steel plates. In addition, the control network and points are drawn on the floor plan, and the project department is required to take practical measures to protect the piles.

Through the above survey of road construction and housing construction, I think that as a qualified surveyor, we must handle all kinds of survey projects well, work with a serious, careful and down-to-earth attitude, sum up experience, find new problems, deal with old problems, and strive to bring you happiness with the spirit of not being afraid of fatigue and environmental hardship.
