Is the design of railway beam storage yard a construction unit or a design unit? Hello.
The Qinghai-Tibet Railway is very high in the world at present, and the unique geographical position of the Qinghai-Tibet Plateau Railway is unique. The quality conditions are extremely complex, and railway construction is facing all kinds of brand-new technical problems. Making the construction organization plan is also a new topic. Our group company undertakes the fifth bid section, starting from the north of Kunlun Mountain and ending at Xitan South to Dongquan, 47.9 1 km. The construction organization plan of this section faces two technical problems: the average elevation of the line is 4500 m, the elevation is nearly 40 km, and the pass of Kunlun Mountain is 4776 m high. Low oxygen content, low temperature, low air pressure, low wind speed, strong radiation, severe thunderstorm and harsh conditions make the project construction face unprecedented difficulties, especially cold and lack of oxygen. The second line is all located in the frozen soil area, passing through the high temperature frozen soil zone and the melting zone on the edge of the frozen soil zone. The hazards of railway engineering construction, such as the degeneration and melting of frozen soil, seasonal thawing layer freezing and melting, and good frozen soil physical phenomena, make the engineering construction in frozen soil area different from that in general areas, and put forward new requirements for construction, construction technology, construction equipment configuration and detection means. In addition to taking effective technical measures to control and eliminate some hazards, it is also the key to the failure of engineering construction.
1 project overview
The line of this bid section passes through Xitan fault basin, Luanshigou gorge area, Kunlun mountain pass, Kunlun mountain pass basin and frozen spring valley, with complex and unique quantities.

2. Mechanical configuration
Because the power drop of internal combustion engine is not serious in cold and oxygen-deficient environment, the motor should be used as much as possible. At present, the digging, loading, transporting and rolling machines for earthwork construction only choose internal combustion type, choose models with turbocharging devices, and have sufficient mechanical reserve capacity. Because the power supply of the power grid in this bid section is all self-provided, the key equipment layout of the generator needs to be carefully studied and solved.
diligent
Formulate nutrition guidelines for plateau construction personnel. Golmud will set up purchasing stations and food processing canteens to minimize the number of processed or semi-finished products of various food raw materials. The cooking procedure on the construction site will strictly follow the nutrition required by the body, and all kinds of food will be sent to various construction sites by special refrigerated trucks.
4. Health care and epidemic prevention
Golmud set up a medical rehabilitation center to treat and recuperate the wounded and sick. The fourth project department at the entrance of Kunlun Mountain Tunnel shall set up a medical first-aid department to be responsible for the on-site first-aid work of operators, and an epidemic prevention station to be responsible for the epidemic prevention and monitoring work of contractors.
Main measures and objectives of medical epidemic prevention:
Personnel involved in the construction shall have a comprehensive physical examination and regular physical examination before entering the site; Disclosure of work environment, medical treatment and health education in advance. In addition to setting up medical first aid at the entrance of Kunlun Mountain Tunnel, medical and health care stations should be set up to prevent self-care and give priority to medical treatment, so as to enhance the awareness of all staff on disease resistance and health care. Medical staff leaders should follow up and observe the physical condition of each employee, shorten working hours as far as possible according to regulations, reduce labor intensity, protect health according to regulations, prepare nutritious meals in the labor protection department, pay attention to cold protection and disease prevention, and take oxygenated drugs. We should prepare enough first-aid supplies and master first-aid techniques.

Who are the design units and construction units of Longting in Laizhou Peninsula? Shandong Gansheng Real Estate Development Co., Ltd. (Fujian Fuzhou Enterprise Development Project Shandong) Peninsula Longting Project Brief Introduction;
Peninsula Longting Project is located in Chenggang South Road, Laizhou City (south of Laizhou Customs), with a total area of 400 mu, which will be constructed in two phases. The first phase covers an area of 244 mu, with 38 planned houses with 5- 17 floors and 1904 households. There are commercial storefronts along the street, which will form a commercial pedestrian street in the future. There are supermarkets in the southeast corner and northeast corner of the community, which provides convenient shopping conditions for the owners of the community.
Peninsula Longting is a multi-functional high-grade residential community integrating residence, leisure, sports and entertainment, which is mainly reflected in supporting and greening the landscape. The main entrance of the pedestrian street is a 6000-square-meter super-large viewing square, which runs through the natural waterscape belt on the east and west sides of the community. Small gardens with different scenery are interspersed between each building, and unique greening plants are available all year round, so that every owner can feel like living in Suzhou gardens. There are also swimming pools, golf putting greens, international bilingual kindergartens, children's play areas, morning exercises centers, basketball courts, squash courts, badminton courts, peninsula cafes and other entertainment and fitness places to provide comprehensive supporting services for every owner.
Another highlight of the Peninsula Longting is the ultra-wide building spacing. The distance between 1 1# building and 12# building is 80m, and the layout of each building is orderly, with frame-plate planning and full-scale design. The humanized design of the community is divided into four entrances and exits, the east-west direction is pedestrian entrance and the north-south direction is vehicle entrance and exit. There is a special driveway, which truly separates people from vehicles and ensures the safety of people moving in the community. There are also 24-hour blind spot monitors, electronic detectors and infrared monitors in the community. The unit door is equipped with color visual intercom, and each household is equipped with anti-theft alarm. These modern security facilities can definitely make the owners feel at ease here. The ratio of garage to residence in the community is 1: 1, which is divided into above-ground and underground garages, and there are 6 entrances and exits of underground parking lots, which provides convenience for car owners.
There are currently 9 buildings in Peninsula Longting, all of which have been capped and the internal partition has been completed. Now the external wall insulation of each building is being done. It is expected to be completely demolished on September 30 this year and will soon become an existing house.
