Question 2: What safety measures are there in the road construction site? Before construction, the site should be treated with "three links and one leveling". If temporary access roads are to be built, the safety of traffic and pedestrians must be ensured. And there are clear signs and traffic control measures. Understand the temporary water and electricity consumption on the construction site through investigation and draw a sketch. Carry out safety education on water and electricity use for all construction personnel, and strictly abide by the system of holding certificates for special personnel.
Before construction, the obvious signs on the buried pipeline should be removed and detailed disclosure should be made to the construction personnel. When digging through dangerous buildings such as cracked walls and skewed chimneys, it is necessary to support and reinforce them in advance. Protective fences shall be set up for leveling points and poles, and feasible safety construction schemes shall be formulated for sections prone to collapse in rainy season.
Hang national safety signs, dangers, warnings, symbols and slogans in the construction area to warn people to pay attention to the scope of protection and dangerous areas.
Question 3: What problems should be paid attention to in the process of safety construction in expressway? Whenever you are careful, you should pay attention to safety, otherwise there are hidden dangers everywhere. Electricity, water, formwork, supports, steel bars, construction machinery and vehicles are all hidden dangers during construction. Please accept if I am helpful to your answer. Thank you.
Question 4: What are the safety points of cement concrete pavement construction? 1. The mixing of cement concrete shall be handled in accordance with the relevant safety technical operation procedures.
2. When transporting concrete with trolleys or small dump trucks, keep a safe distance between vehicles.

6, when using vibrator, should be handled in accordance with the provisions of the relevant regulations.
7, remove the wooden pattern should be nailed in time, neatly stacked.
8, rail cement concrete paver paving, shall comply with the following provisions:
(1) A safe distance of 5~8m should be kept between the spreader and the leveler;
(2) The tightness of the transmission steel wire of the cloth feeder should be moderate. Don't put the scraper in a position perpendicular to the running direction, and don't use the inertia of the whole machine to impact the material pile;
(3) It is forbidden for the driver to leave the bridge without authorization during the operation. Irrelevant personnel shall not stay in the cab or get up and down the paver. When working on curves, attention should be paid to prevent the paver from derailing.
9, slipform cement concrete paver paving, shall comply with the following provisions:
(1) The parking place should be flat and solid, and the fuselage should be padded with solid wood blocks. The track shoe can be adjusted and installed only after it leaves the ground;
(2) When adjusting the height of the machine, no one is allowed to stand on the work pedal and escalator. It is forbidden to collide with the guide wire during operation;
(3) The paver should avoid emergency steering and collision with embedded steel bars and kerbs;
(4) Paver shall not pull other machinery; Other mechanical traction pavers should use rigid traction rods;
(5) When the paver is parked on the open road, obvious safety signs must be set around it. Warning with red light at night, visibility is not less than150m.
10, vacuum suction cooperation, it is forbidden for operators to walk on the suction pad or put objects on the suction pad.
1 1. When using the cement concrete trowel, make sure that the blade of the trowel is smooth and smooth, the connecting bolt is not loose, and start it under no load. The cable should be kept by a special person to ensure that it is not knotted or crushed. If abnormal phenomena are found, stop the vehicle immediately for inspection.
Question 5: What are the safety standards for road construction? The safety standard is mainly the Road Traffic Safety Law of the People's Republic of China, and some local safety laws and regulations and safe construction methods are also referenced.
According to Article 105 of the Road Traffic Safety Law of the People's Republic of China, if warning signs and protective measures are not set in time due to road construction or road damage, or traffic lights, traffic signs and traffic markings should be set but not set or changed in time, resulting in the loss of pedestrians, vehicles and other property, the unit responsible for factory cleaning shall be liable for compensation according to law. We believe that one of the reasons for this accident is that the defendant should change the traffic lights and traffic markings in time during road construction, and should bear the responsibility according to law.
The following explanation is as follows:
1, the standard of setting up obvious signs and taking safety measures is generally considered to be enough for anyone to take normal care and avoid losses. To determine this standard, we can consider the standards adopted, one is anyone and the other is ordinary people. It's too harsh to take anyone as a standard. We think it is more appropriate to adopt the standard of ordinary people. Under normal circumstances, the construction party can set up obvious signs and take safety measures to prevent ordinary people from suffering losses.
2. The phrase "no obvious signs are set and no safety measures are taken" can be understood not only as inaction, but also as negative actions despite actions. That is, although signs are set up, they are not enough to attract the attention of others. Although certain protective measures are taken, they are not enough to play a normal role in safety protection.
3. These signs and measures should be sufficient to ensure all normal activities on the construction site, and protect passers-by from dangerous factors (such as pits, ditches and obstacles) formed during construction. Therefore, if obvious signs are set and safety measures are taken, it may still constitute a violation of dangerous obligations when it is not enough to ensure the safety of others. For example, an engineering team dug deep trenches and buried pipelines in expressway. Although signs were erected on the construction site, there was no lighting at the signs, which caused vehicles driving at night to fall into the ditch. In this case, the construction team still violated the duty of care.
I think the situation you mentioned belongs to the third point in the Interpretation: it may still constitute a violation of dangerous obligations if it is not enough to ensure the safety of others.
Question 6: What are the construction preparations for road construction site safety measures?
Before construction, the site should be treated with "three links and one leveling". If temporary access roads are to be built, the safety of traffic and pedestrians must be ensured. And there are clear signs and traffic control measures. Understand the temporary water and electricity consumption on the construction site through investigation and draw a sketch. Carry out safety education on water and electricity use for all construction personnel, and strictly abide by the system of holding certificates for special personnel.
Roadbed construction safety
Before subgrade construction, strict construction organization design, strict construction specifications and safety technical operation procedures should be formulated, on-site command and dispatch personnel should be implemented, safety technical disclosure should be made to all construction personnel, and safety protection facilities should be set up at the construction site to provide necessary safety protection articles for construction personnel. Everything is ready before subgrade construction can begin.
Construction safety of base course and surface course
During concrete construction at the grass-roots level, attention should be paid to preventing environmental pollution and affecting residents' physical and mental health, and fences should be set up when necessary. No one is allowed to stand around the machine. In order to ensure that the machine can move forward and backward freely, there must be a special person at the scene to prevent personal injury. During paving construction, construction personnel should pay attention to avoid construction machinery in time and obey the on-site command. After the construction, the site must be cleaned up, and the remaining materials must not be dumped on the roadside, which will affect the safety of pedestrians.
Construction safety of ancillary structures
Precast masonry construction: when transporting precast blocks, first check whether there are cracks in the precast blocks to prevent personal injury caused by sudden fracture during transportation. When handling, two people should carry each other and pile up neatly and smoothly. In the process of handling, the two coordinated to prevent squeezing hands and feet. When installing, please hold it firmly and move it carefully. After the erection is completed, pedestrians and vehicles are prohibited from colliding during the maintenance period. When building a well: workers must wear safety helmets correctly. Bricks and stones are transported down through chutes or lifts. When lifting, the rope must be strong and fastened, and the upper and lower workers should cooperate with each other. When the build-by-laying well exceeds 1.2m, scaffolding or simple shelves must be erected. When laying, bricks, stones and tools should be prevented from falling and hurting people.
Question 7: What should be paid attention to in winter safety of construction roads? 1. Before construction, necessary investigations should be made on underground pipelines, and obvious signs should be made to prevent accidents such as water leakage, air leakage, electric leakage and explosion burns during construction.
2. Do a good job in the safety protection of key facilities such as site leveling points and poles.
