Safety precautions for road construction

Question 1: What should we pay attention to when it comes to road construction safety? Paragraph 2 of Article 32 of the "Road Traffic Safety Law of the People's Republic of China" stipulates: The construction unit shall carry out construction operations within the approved road section and time, and at a safe distance from the construction site in the direction of oncoming traffic. Set up obvious safety warning signs and take protective measures; after construction work is completed, obstacles on the road should be quickly removed to eliminate safety hazards. Traffic can only be resumed after passing the inspection by the road authority and the traffic management department of the public security organ and meeting the traffic requirements. .

Question 2: What are the safety measures at road construction sites? Before construction, the site must be treated with "three connections and one leveling". When building temporary access roads, the safety of vehicles and pedestrians must be ensured. There are clear signs and traffic control measures. Conduct surveys to understand the temporary water and electricity consumption at the construction site and draw sketches. Provide water and electricity safety education to all construction workers, and strictly abide by the certification system for special staff.

Before construction, clearly mark the pipelines buried underground and provide detailed explanations to the construction personnel. When excavation passes through dangerous structures such as cracked walls and crooked chimneys, they must be supported and reinforced in advance. Set up protective fences at benchmark points and electric poles, and formulate practical and feasible safety construction plans for road sections prone to landslides during rainy season construction.

Safety signs, dangers, warnings, symbols and slogans prescribed by the state are hung in the construction area to warn people of the scope of protection and dangerous areas.

Question 3: What issues should be paid attention to during the construction process of highway safety? You must be careful and pay attention to safety at all times, otherwise there will be hidden dangers everywhere. The use of electricity, water, formwork, supports, steel bars, construction machinery and vehicles during the construction process are all hidden dangers. If my answer is helpful to you, please accept it, thank you.

Question 4: What are the safety points for cement concrete pavement construction? 1. The mixing of cement concrete should be handled in accordance with relevant safety technical operating procedures.

2. Use trolleys or small dump trucks to transport concrete, and keep a certain safe distance between vehicles.

3. When cement concrete trucks transport concrete mixtures, the following regulations should be observed:

(1) Hydraulic pumps, hydraulic motors and valves should be strong and firmly connected to the pipelines , well sealed. There should be no jamming or abnormal noise when each pump rotates;

(2) When the transmission system fails and the hydraulic oil output is interrupted, causing the drum to stop rotating and cannot be repaired for a while, the emergency discharge system must be used to quickly Discharge the concrete mixture;

(3) It is strictly forbidden to touch the rotating mixing drum and follower wheel with your hands.

4. Dump trucks transporting concrete mixtures must not be overloaded or speeded. After the car has stopped, lift the carriage to unload the materials. Operators are not allowed to get on the car to remove residual materials before the car is put down.

5. When loading and unloading steel molds, you must lift them piece by piece with care and do not throw them randomly.

6. When using the vibrator, it should be handled in accordance with the relevant regulations.

7. The removed wooden formwork should be nailed out in time and stacked neatly.

8. When paving rail-type cement concrete paver, the following regulations should be observed:

(1) A safety distance of 5~8m should be maintained between the placing machine and the vibrating machine. distance;

(2) The tightness of the transmission wire of the cloth machine should be moderate. The scraper shall not be placed in a vertical position in the running direction, nor shall it impact the material pile with the inertia of the whole machine;

(3) The driver is strictly prohibited from leaving the driving platform without authorization during operation. Unauthorized personnel are not allowed to stay on the cab or get on or off the paver. When working on curves, be careful to prevent the paver from derailing.

9. When paving with a sliding mode cement concrete paver, the following regulations should be observed:

(1) The stopping place should be flat, solid, and padded with solid wooden blocks. Lift the body. Adjustment and installation can only be done after the track pads are off the ground;

(2) When adjusting the height of the machine, no one is allowed to stand on the working pedals, escalators, etc.

It is strictly prohibited to collide with the guide line during operation;

(3) The paver should avoid emergency steering and prevent collision with embedded steel bars, road curbs, etc.;

(4) Paver No other machinery is allowed to be towed; when other machinery tows the paver, a rigid tow bar should be used;

(5) When the paver is parked on the access road, obvious safety signs must be set around it. A red light should be used as a warning at night, and its visibility should not be less than 150m.

10. During vacuum suction operations, operators are strictly prohibited from walking on the suction pad or placing objects on the suction pad.

11. When using a cement concrete trowel, make sure that the blades of the trowel are smooth and flat and at the same level. The connecting bolts should be tightened and not loose, and should be started under no load. There must be a dedicated person to retract and unwind the cables to ensure that they are not knotted or crushed. If any abnormality is found, the machine should be stopped immediately for inspection.

Question 5: What are the safety standards for road construction operations? The safety standards are mainly the "Road Traffic Safety Law of the People's Republic of China" and some safety regulations and safe construction methods of the local government.

According to the "Road Traffic Safety Law of the People's Republic of China and the State" Article 105 of the Road Traffic Safety Law: Road construction operations or road damage, failure to promptly set up warning signs and failure to take protective measures, or failing to set up traffic lights, traffic signs, and traffic markings when they should be, or failing to change traffic lights in a timely manner If traffic lights, traffic signs, and traffic markings are not changed in a timely manner, causing losses to passing people, vehicles, and other property, the unit with factory-related responsibilities shall be liable for compensation in accordance with the law. "We believe that the defendant should be timely during road construction operations. Changing traffic lights and traffic markings without changing them in time was one of the causes of the accident, and he should be held responsible according to law.

The following explanation is as follows:

1. The standards for setting up obvious signs and taking safety measures are generally considered to be sufficient for anyone to take ordinary care and avoid losses. To determine this standard, the standards that can be considered are: first, anyone, and second, ordinary people. It’s too harsh a standard to hold anyone else to standards. We believe that it is more appropriate to adopt the standards of ordinary people. If construction workers set up obvious signs and take safety measures, ordinary people can avoid losses under normal circumstances.

2. The term "failure to set up obvious signs and take safety measures" cannot only be understood as a failure to do anything. It also includes the situation where something has been done but it is a negative action. That is, although signs are set up, the signs are not enough to attract the attention of others, and although certain protective measures are taken, the measures are not enough to play a normal safety protection role.

3. These signs and measures must be sufficient to ensure that all normal activities at the construction site are carried out and that passers-by are protected from hazards caused by construction (such as pits, ditches, obstacles). Therefore, if obvious signs are set up and safety measures are taken, but they are not sufficient to ensure the safety of others, it may still constitute a violation of the danger obligation. For example, a construction team dug a deep ditch on a highway to bury a pipeline. Although there was a sign at the construction site, no lighting was installed at the sign, causing vehicles traveling at night to fall into the ditch. In this case, the project The team still constitutes a breach of duty of care.

I think the case you are talking about belongs to the third point in the explanation: when it is not enough to ensure the safety of others, it may still constitute a violation of the danger obligation.

Question 6: What are the safety measures for road construction sites? Construction preparations

Before construction, the site must be treated with "three connections and one leveling". When building temporary access roads, the safety of vehicles and pedestrians must be ensured. There are clear signs and traffic control measures. Conduct surveys to understand the temporary water and electricity consumption at the construction site and draw sketches. Provide water and electricity safety education to all construction workers, and strictly abide by the certification system for special staff.

Subgrade construction safety

Before subgrade construction, a strict construction organization design should be prepared, strict construction specifications and safety technical operating procedures should be formulated, on-site command and dispatch personnel should be implemented, and all construction personnel should be Conduct safety technical briefings, arrange construction site safety protection facilities, and equip construction workers with necessary safety protection supplies. Only when everything is ready can the roadbed construction begin.

Construction safety of base layer and surface layer

When constructing the base layer of composite soil, attention should be paid to preventing environmental pollution and affecting the physical and mental health of residents. Fences should be set up when necessary. No one is allowed to stand around the machine. To ensure that the machine can move forward and backward freely, there must be a dedicated person on site to direct the machine to prevent personal injury or death. During paving construction, construction workers should pay attention to avoid construction machinery in time and obey on-site instructions. After the construction is completed, the site must be cleaned up, and remaining materials must not be dumped on the roadside to affect pedestrian safety.

Construction safety of ancillary structures

During construction of precast masonry: When transporting precast blocks, you should first check whether there are any cracks in the precast blocks to prevent sudden breakage and injury during transport. When transporting, two people should carry each other and stack them neatly and steadily. During the transportation, the two of them coordinated to prevent their hands and feet from being crushed. When installing, hold it firmly and be careful when moving. After the installation is completed, collisions between pedestrians and vehicles are prohibited during the health maintenance period. During well construction: Workers must wear safety helmets correctly. Use chute or hoist to transport bricks and stones downward. When lifting, the rope must be strong and tied tightly, and the upper and lower workers must cooperate in a consistent manner. When the well is more than 1.2 meters long, scaffolding or simple shelves must be set up. When building masonry, prevent bricks, stones, tools, etc. from falling and injuring people.

Question 7: What should be paid attention to for winter safety on construction roads? 1. Necessary surveys of underground pipelines should be carried out before construction, and obvious signs should be made to prevent water leakage, air leakage, electricity leakage, explosion burns and other accidents during construction.

2. Provide safety protection for key facilities such as on-site leveling points and electric poles.

3. Set up safety patrols at construction intersections to guide vehicles and pedestrians around safe areas.

4. When bending pipes manually, the site should be selected to prevent slipping and falling, and the face should be avoided during operation.

5. All insulation and inspection tools should be properly kept, other uses are strictly prohibited, and should be inspected regularly.

6. The rated current of the fuse used in electrical equipment should be consistent with its attached capacity. It is prohibited to replace the fuse with other metal wires.

7. Wires for lighting installations in offices, dormitories, etc. should be fixed with insulators. Do not use fancy wires or plastic wires to pull them randomly.

8. The insulation of various wires used on site must not be subject to aging, breakage, leakage, etc.

9. High and low voltage equipment and lines used for on-site construction should be installed and erected in accordance with the construction design and relevant electrical safety design regulations.

10. It is forbidden to connect or cut off the power with load on the line, and it is forbidden to operate under power.

11. If someone gets an electric shock, you should immediately cut off the power supply and provide first aid; if there is an electrical fire, you should immediately cut off the relevant power supply and use a foam fire extinguisher or dry sand to extinguish the fire.

12. When installing lighting circuits, it is not allowed to pass or stack materials directly on the slatted ceiling or sound insulation board. When traffic is necessary, scaffolding should be laid on the large corrugations.

Question 8: What safety should be paid attention to at the highway construction site? 20 points 1. Implement the policy of "safety first, prevention first" and adhere to the principle that safety must be managed when managing production.

2. Before the start of construction, the construction organization design (or construction plan) must have detailed construction floor plans, transportation roads, temporary power line layout and other work arrangements, all of which must meet safety requirements. .

3. The site should be surrounded by an enclosure that is isolated from the outside world. The construction site layout plan, safety production record board, project overview board and other safety-related equipment should be installed at the entrance.

4. On-site drainage must be comprehensively planned in advance, and drainage ditches should be regularly cleaned and dredged to maintain smooth flow.

5. Road transportation should be smooth and smooth.

6. Materials stacked on site must be classified and stacked neatly and stably according to the locations specified on the site layout. Remaining materials such as wood and steel pipes left during the operation should be cleaned up in time.

7. Safety construction at the construction site, such as safety nets, guard poles, various limiting and safety devices, etc. must be complete and effective, and must not be dismantled or moved without authorization.

8. Power distribution, protection devices, lightning protection, and electricity safety measures at the construction site must be carried out in strict accordance with regulations.

10. The safety management of fire, electricity and explosive items, on-site fire protection facilities and fire protection responsibility system should be carefully considered and implemented in accordance with fire protection requirements.

11. Temporary warehouses, dormitories, canteens, work sheds, etc. set up on site must meet safety and fire prevention requirements.

Question 9: What are the safety precautions for highway construction? Pay attention to dangerous obstacles, viaducts, etc.

Question 10: What should you pay attention to during highway construction? 1. Instructions for construction operations

1. It is prohibited to mix mortar directly on the road surface. Construction materials that will cause pollution or damage to the road surface must be unloaded on isolation layers such as colored strips of cloth, linoleum felt, wooden boards, steel plates, etc. when transported to the site. They must not be placed directly on on the road.

2. When constructing on high embankment shoulders, steep slopes and other road sections, anti-slip and fall measures should be taken, and attention should be paid to preventing dangerous rocks and pumice from rolling down.

3. During maintenance (rescue) operations on landslides, landslides, debris flows and other road sections, dedicated personnel should be assigned to observe dangerous situations.

4. Construction workers are prohibited from working in heavy fog, strong wind, or heavy rain.

5. During construction operations in the rainy season, accumulated water should be removed from the work site in time. Steps should be dug or sand should be dug up and down the sidewalk, and anti-slip measures should be taken on ramps and springboards. Strengthen inspections of racks, scaffolding and earthworks to prevent tilting and collapse.

6. Any situation that is too late to arrange and directly affects traffic safety must be handled with an emergency plan. For serious slope collapses, colored strips of cloth should be used to cover the surface and the collapsed objects on site should be cleaned up at the same time. Wait for emergency measures. 7. Before the end of the project, all signs, operating facilities, and materials at the construction site should be cleared away. Construction machinery, materials, and waste debris are not allowed to be placed on the road surface, central separation belt, road shoulders, or slopes to ensure that the road appearance is clean and tidy.

2. Safety Precautions

1. Persons who have not applied for simple personal insurance, work-related injury insurance and have not participated in safety training are not allowed to operate on the highway; vehicles in poor condition and severely overloaded (limited) Vehicles that are wet, dripping, spilling or leaking are not allowed to enter the highway construction.

2. Personnel carrying out maintenance and construction work on the highway must wear vests with reflective markings; it is strictly prohibited to cross the highway without safety assurance, and should walk outside the roadside guardrail when commuting. Yellow strobe lights should be turned on when vehicles are driving and operating, and safety guards must be posted at each construction site.

3. When working within the guardrail, regardless of the workload, the control must be in accordance with regulations. Reflective cones or anti-collision walls should be added to the control area. Construction personnel, vehicles and machinery should be within the control area and are not allowed to leave without authorization. Posts, it is not allowed to change the traffic control area or expand the work area at will; it is strictly prohibited to make a U-turn from the opening of the movable guardrail in the central separation zone of the highway.

4. The appropriate distance between reflective cones is 15 meters. When placing reflective cones, the deployment control personnel should be in the deployment control area. After the cones are placed, the safety officer should stand in a safe position behind the reflective cones to conduct safety instructions, and regularly move or dump the deployed reflective cones and signs. Adjust or straighten.

5. During tunnel maintenance and repair, construction signs, speed limit signs, guide signs and width limit signs must be set up in front of the tunnel entrance.

6. For the layout of the control area for maintenance and repair operations of extra-large bridges, it is advisable to close only one lane for maintenance and repair operations.

7. Drivers should strictly control the driving speed, strictly prohibit drunk driving, and strictly abide by the "Ten Don'ts for Safe Operation of Mechanical Vehicles"
