How to carry out safe production in pile foundation construction

1. Strengthening construction safety management (1) The person in charge of the engineering construction unit (project management department) must be fully responsible for the safety production work of the engineering construction, clarify that he is the first person responsible for safety production, and is responsible for establishing The safety management organization implements the safety production responsibility system, determines the job safety responsibilities of leading cadres, managers and employees, and organizes the formulation and implementation of safety measures and rules and regulations that are consistent with on-site production. It is necessary to conscientiously implement the policy of "safety first, prevention first" and implement the safety rules and regulations of the national and local industry authorities. (2) The construction unit must set up a production safety leadership group with full-time (part-time) safety officers to assist leaders in implementing safety rules and regulations, organize and carry out safety activities, insist on inspection and guidance of production safety at the job site, and solve problems in production safety, Discourage illegal commands and stop illegal operations. They are also responsible for educating and training new workers and temporary workers on on-site safety knowledge and safe operation skills, writing safety production technology designs and measures for construction projects, and conscientiously doing daily safety management work. (3) The construction unit must establish a safety inspection and safety education system, and insist on conducting safety production inspections and safety education and training in accordance with regulations. Before the start of the project, the safe production conditions of the work site must be inspected and submitted to the competent department for review and approval before construction can start. During the construction period, inspections should be conducted once a month; the machine should be inspected once a week, and any problems and accidents found should be reviewed. For hidden dangers, measures must be formulated, implemented by people, and rectified within a time limit. (4) The team must adhere to the shift handover system. The team leader should assign work tasks and explain safety precautions before the shift. They should summarize after the shift and criticize violations. When handing over the shift, the operators should inspect the machinery they use. Equipment and tools should be inspected in detail, and if any unsafe factors are found, they should be dealt with and reported in a timely manner. (5) On-site workers must receive safety management, safety education and safety skills training. Special types of work, such as electricians, welders, crane workers, blasters and motor vehicle drivers, must undergo strict training and assessment and must hold certificates to work. Operation. (6) Operators should strictly abide by labor disciplines and safety regulations at work. They should not fight, leave their jobs without authorization, and should not drink alcohol before going to work. They should wear labor protection supplies, work clothes, and safety helmets. They are not allowed to wear slippers. Safety belts must be worn when working on the tower. (7) Clear and eye-catching safety responsibility signs and safety discipline (or safety management regulations) placards should be hung at the construction site, and safety warning signs should also be hung at dangerous locations. (8) Operators must obey instructions when multiple people are working together. They have the right to refuse to accept illegal and risky instructions, and have the right and obligation to promptly report and deal with dangerous situations and carry out accident rescue. (9) Accidents must be reported step by step in accordance with regulations, organize investigation and handling, identify the cause of the accident, and take serious measures to prevent similar accidents from happening.

2. Carefully make safety arrangements for the pile foundation construction site (1) Before entering the construction site, you must conduct a survey of the construction site to clarify the high-voltage lines, underground pipelines, communication cables and other structures on the site; the construction site should have "three links" According to the construction conditions of "one level", the construction site should have sewage pits, sewage pools and other facilities to achieve civilized production. (2) Safety signs should be set up at the construction site, and safety warning signs should be set up at dangerous locations; power supply lines within the construction site should be elevated or buried in trenches, and the insulation condition of electrical lines should meet safety requirements; adequate lighting should be provided for nighttime production.

3. Strengthen the safety and protection of pile foundation construction equipment (1) The drilling frame and platform must be installed smoothly, squarely and firmly, and the parts must be complete; the open gear, belt drive and exposed rotating shaft head must be installed properly. Protective railings or protective covers should be provided. (2) The wooden track of the abutment must be stable and of appropriate length; the platform board must be non-slip and firm; the tower ladder, workbench, and railings must be installed firmly and reliably; the upper part of the drilling frame must have a workbench that is convenient for high-altitude operations; the water drilling platform must be It should be sturdy and secure and not affected by water flow. (3) The distance between the top of the drill frame and the high-voltage power supply line complies with safety regulations or meets safety requirements; the distribution box must be equipped with leakage protectors and other safety facilities, there are rainproof measures outside the cabinet, and the shell of electrical equipment is equipped with protective grounding or zero connection. ; Electrical switches must be intact, fuses, fuses, etc. are used according to regulations. They are not allowed to exceed the rated standards or be replaced with copper wire or iron wire. (4) Dangerous parts of the construction site should be equipped with corresponding safety protection facilities; and sufficient fire prevention facilities should be equipped. (5) The wire rope and rope clamp used for lifting must be safe and reliable.

IV. Strict safety operations in pile foundation construction (1) Each shift should inspect the bolts of the platform, drilling frame, lifting system, mechanical equipment and other parts.

(2) When the drilling frame and platform are moved, no people or untied floating objects are allowed on the tower and platform; when using the SPJ-300 trailer drill or truck-mounted drilling rig to move, the tower should be placed first and then moved; There should be unified command when installing and dismantling the platform and drilling rig. (3) When working at high altitude, all tools and items must be put into tool bags to prevent items from falling; no work is allowed on or below the tower at the same time, and tools and items are not allowed to be thrown. (4) When the universal shaft of the drilling rig rotates, personnel are not allowed to cross or stand on the turntable; when lifting the drill bit, the wellhead personnel must stand outside the dumping range of the drilling tool; when lifting the puller, the rotation of the vertical shaft must be stopped and someone should be supervised switch. (5) When the machine is running, it is not allowed to disassemble and repair parts, nor to scrub; it is not allowed to wear gloves to pick up or hang the belt or wax it; it is not allowed to use iron tools to pull the belt; it is not allowed to pull, touch or step on the running wire rope. . (6) Before lowering the steel cage, clear the obstacles around the opening; when lowering the steel cage, people are prohibited from climbing on the steel cage to add weight; when lifting the steel cage or conduit, a steel wire rope with a diameter greater than 10mm must be used. Wire ropes exceeding the specified wear degree should be replace. (7) Fire, smoking, and cigarette butts are not allowed around acetylene bottles and oxygen bottles; when welding steel cages on the construction site, the safety operating procedures for electric and gas welding must be strictly followed. (8) Dump trucks can only be used on construction sites and are not allowed to be driven on highways, used as a means of transportation, or carry people.
