Safety management of pile foundation construction?

The current situation of safety management in pile foundation construction

Leaders do not pay attention to it. Some enterprise leaders have insufficient understanding, focus on production, ignore safety, and have weak safety awareness. They only issue production targets to employees without providing safety guarantees. They even fail to investigate and deal with accidents seriously, passing on safety risks to subcontracting units and employees, making safety Not guaranteed.

Weak security management. Some safety rules and regulations are incomplete, management is irregular, and subjective and arbitrary; some have not established safety management agencies, and safety management is out of control. Accident hazards can be seen everywhere, and various types of accidents occur from time to time.

The safety awareness of construction workers is weak and the control of illegal operations is not strict. Some construction units have lax on-site management, and the construction site and operation teams have orders and prohibitions, and management is not strict and responsibilities are not implemented. Labor protection equipment for construction workers cannot be guaranteed. Management, command, and operating personnel lack appropriate safety technical knowledge, and the equipment is old, aging, and operating in a sick manner. The "three violations" of illegal command, illegal operation, and violation of labor disciplines are common, and there are many hidden dangers of accidents.

Insufficient investment in safety production costs at construction sites. Although everyone from top to bottom calls for special funds for production safety expenses, the project department, in terms of construction planning and implementation of measures, uses the slogan of increasing efficiency and reducing consumption, but actually cuts several cuts in production safety expenses. Major accident hazards cannot be rectified in time, which has become a long-standing problem.

Safety responsibilities are not clear. In production and operation contracting, the phenomenon of "one package" and layered subcontracting are relatively common, responsibilities are unclear, and safety management is unstructured.

Countermeasures for safe production in pile foundation construction

1. Strengthen construction safety management

Improve the organizational structure of the project department. 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, be responsible for establishing a safety management organization, implement a safety production responsibility system, and determine leading cadres and managers and employees’ job safety responsibilities, and organize the formulation and implementation of safety measures and rules and regulations that are consistent with on-site production. We must conscientiously implement the policy of "safety first, prevention first" and implement the safety rules and regulations of the national and local industry authorities. 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, adhere to the inspection and guidance of safety production at the work site, solve problems in safety production, and discourage illegal commanding , to 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.

Establish and improve safety systems. Adhere to safety production inspections and safety education and training in accordance with regulations. Before the start of the project, the safety 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. The team must adhere to the shift handover system. The team leader should assign work tasks and explain safety precautions before the shift. After the shift, the team leader should make a summary and criticize violations. When handing over the shift, the operators should inspect the mechanical equipment and tools they use. Detailed inspections should be carried out and unsafe factors discovered should be dealt with and reported in a timely manner.

Strengthen safety publicity and education work. 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. 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.

2. Carefully carry out safety arrangements and protection at the pile foundation construction site

(1) Before entering the construction site, you must conduct a survey of the construction site and clarify the high-voltage lines, underground pipelines, and communication cables in the site and other structures; the construction site should have the construction conditions of “three connections and one leveling”, and 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; the power supply lines in the construction site should be overhead or buried in trenches, and the insulation condition of the electrical lines should meet safety requirements; night production must have Adequate lighting.

(3) 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 should all be equipped with protective railings or protective covers.

(4) The wooden track of the abutment must be stable and of appropriate length; the platform board must be non-slip and firm; the installation of tower ladders, workbench and railings must be firm and reliable; the upper part of the drill frame must be convenient for high-altitude operations. workbench; the water drilling platform must be solid and reliable and not affected by water flow.

(5) The distance between the top of the drill frame and the high-voltage power supply line must comply with safety regulations or meet safety requirements; the distribution box must be equipped with leakage protectors and other safety facilities, and there must be rain-proof measures outside the cabinet, and electrical equipment casings It is equipped with protective grounding or zero connection; the electrical switch must be intact, and fuses, fuses, etc. are used according to regulations. They are not allowed to exceed the rated standard or be replaced with copper wire or iron wire.

(6) Dangerous parts of the construction site should be equipped with corresponding safety protection facilities; and adequate fire prevention facilities should be equipped.

(7) The wire ropes and rope clamps used for lifting must be safe and reliable.

3. Strictly implement safe operation of 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 rig 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 and platform should be placed first The tower and rear shift; when moving the platform and installing and dismantling the drilling rig, someone should provide unified command.

(3) When working at height, 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 cardan 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 picking up and hanging the lifter, they must Stop the vertical shaft rotation and have someone watch the 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 or stroke it. , the pedal is running on the 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 that exceed the specified degree of wear should be replaced.

(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.
