1. The project manager shall provide the company with copies of all qualifications (management personnel, construction personnel and special operations personnel) and my ID card five days before the start of the construction project, and report them to the company for the record.
Second, before each construction project starts, the project manager should lead relevant personnel to conduct on-the-spot investigation and risk assessment on the construction site and working environment, and make preparations for various safety precautions.
Three, all the construction personnel to participate in this project before entering the site construction, quality and safety technical training, and training content, training place, the signature of the teacher and the trainee himself. Technical personnel shall prepare the construction organization design of the construction project, and the construction plan shall be approved and signed by the construction unit and supervision unit before the start of construction. For each part of the operation project, the engineering and technical personnel of the project department shall prepare a technical disclosure sheet for engineering, quality and safety, which shall be signed by the construction operation team leader, receiver and disclosure person. Before every day's operation, the team leader should arrange safety and quality related matters in advance to prevent problems before they happen. Special operations personnel should hold relevant certificates.
Four, road engineering construction, drainage engineering construction before foundation pit excavation, we should carefully study the geological and hydrological data of the whole construction area, the distribution of underground pipe network and adjacent buildings and structures, the requirements of digging soil, construction environment and climate conditions. , and prepare special construction organization design (scheme) to formulate targeted safety technical measures. Blind construction is strictly prohibited.
Five, the construction project should get in touch with the relevant units in advance before the start of construction, and their units should assign special personnel to find out the specific location of the underground pipe network (five pipes and four lines) on the spot, and delimit the area by manual excavation, and mechanical excavation is not allowed.
Six, in the building equipment foundation, railways, poles and all kinds of shelves near digging, according to the soil conditions and depth, formulate reasonable safety construction scheme, the construction can be carried out after approval.
Seven, the construction site to remove weeds, trees, etc. It is forbidden to set fire to prevent fire accidents.
Eight, before cutting down trees, must obtain the approval of the landscaping management department, can be cut down. Before cutting down trees, you should clear the grass and sundries around you, and choose a safe escape route. A warning zone shall be set up within the scope of cutting down trees, and non-working personnel shall not stay or approach. Take safety measures for the injured after the trees are cut down. Logging operations are not allowed in strong winds, fog and rainy days.
Nine, demolition of buildings (structures), should be connected to the demolition of power supply, water supply, gas supply pipeline cut off, and set up a safety fence around the dangerous area, non-working personnel are not allowed to enter. Demolition process should be top-down, first inside and then outside, and it is forbidden to operate several layers at the same time. The structures in danger of collapse should be temporarily supported and strengthened, and the beams and columns can only be removed after all the supported structures are removed. It is forbidden to use hollowing out, hollowing out or knocking down a large area. When excavating earthwork and foundation pit manually, the earthwork excavation personnel must keep enough safe distance, and the earthwork excavation must be carried out from top to bottom in an orderly manner. It is forbidden to use the operation method of hollowing out the footing.
Ten, when using mechanical excavation foundation trench earthwork to observe the change of soil wall at any time,
If cracks or local collapse are found in the soil wall, the construction can be continued only after supporting or changing the gentle slope in time, pay attention to the stability of supporting and the change of slope, stop the construction when necessary, analyze the reasons and take corresponding measures.
1 1. Measures such as drainage and seepage prevention should be taken after foundation trench excavation. Temporary drainage facilities (intercepting ditch, drainage ditch, seepage ditch) should be used together with the water pump, and dredging should be done in time after rain to prevent sedimentation and erosion of the foundation trench.
Twelve, construction personnel should first dig a ladder or take a wooden ladder up and down the groove, and may not trample on the earth wall or support to climb up and down.
13. Abandoned soil, materials and mobile construction machinery should be piled up at the edge of the foundation pit and keep a safe distance from the pit. When the soil quality is good, the spoil should be away from the pit edge1.2m, and the height of the pile should not exceed1.5m..
Fourteen, excavation of retaining wall foundation groove should be from both sides to the middle section of the job-hopping, and strengthen support, timely masonry and backfill the back of the wall. During the construction, special personnel shall be assigned to observe, and on-duty observation and detection shall be carried out at any time to prevent landslides.
15. In road construction, there should be a special person to direct the crossover operation, and heavy vehicles should avoid when they meet. When passing through narrow roads, intersections, busy traffic areas and turning intersections, pedestrians and vehicles should be instructed to pay attention to safety. The distance between the two vehicles before and after the heavy vehicle operation should be kept outside10m, and the distance between the two vehicles on the downhill section should not be less than15m. Construction vehicles are forbidden to carry people, and fences and warning lights should be set up in dangerous areas.
