Introduction of safety protection measures for foundation pit excavation?

Speaking of safety protection measures for foundation pit excavation, at this stage, in order to ensure the safety protection measures for foundation pit excavation, how do construction enterprises do well the safety protection measures for foundation pit excavation? What is the basic situation? The following is the related content of safety protection measures for foundation pit excavation combed by Zhong Da Consulting Bian Xiao Company, and the basic situation is as follows:

Foundation pit is a soil pit excavated at the design position of foundation according to the foundation elevation and plane size. Before excavation, the excavation scheme shall be determined according to geological and hydrological data and the situation of buildings near the site, and waterproof and drainage work shall be done well. If the excavation is not deep, the slope can be placed to stabilize the soil slope, and the slope size is determined according to the relevant engineering regulations. Deep foundation pits and adjacent buildings can be protected by foundation pit wall protection method and shotcrete wall protection method, and large foundation pits even use underground continuous wall and column bored pile chain method to prevent the collapse of outer soil layer; If there is no impact on nearby buildings, well point method can be used to reduce the groundwater level, and slope excavation can be used; In cold areas, natural air conditioning freezing method can be used for excavation.

Zhong Da Consulting Bianxiao Company has compiled the basic situation of safety protection measures for foundation pit excavation through relevant contents, and the basic contents are as follows:

1, conscientiously implement the laws and regulations of the state, industry and local governments on production safety, establish and improve the construction safety inspection and supervision network system, and do a good job in safety inspection and guarantee by stages and parts to make it regular, institutionalized and standardized.

2. Establish and improve the responsibility system for production safety: establish the responsibility system for production safety at all levels, clarify the responsibilities, implement them to people, and strictly implement the manager responsibility system; When signing various economic contracts, there should be clear safety indicators, rewards and punishments and other safety assurance measures; The parties to the contract or joint venture shall sign a safety production agreement according to relevant laws and regulations, so as to ensure that the subject is legal, the content is legal, the procedure is legal, and the rights and obligations are clear.

3. Safety education: implement three-level education for new workers: headquarters, project department and team, and implement new post safety education for workers who change jobs, and make records in time; Workers must be familiar with the safety technical operation procedures of this type of work and master the operation skills of this type of work.

4, the construction organization design should be based on the characteristics of the project, construction methods, the use of mechanical equipment, electricity, special operations, production environment and seasonal influence to develop corresponding safety technical measures and approval procedures.

5, partial project before construction, managers at all levels should conduct a comprehensive and targeted safety technical disclosure, and perform the signing formalities.

6, all special operations personnel must carry out the system of related certificates, homework personnel strict training as required, and after passing the examination can mount guard. It is strictly forbidden to operate without a license.

7. Safety inspection: establish a safety inspection system at all levels, with time and requirements, and define key and dangerous parts; The inspection records are complete, and the hidden dangers are rectified to people, regularly and resolutely; Used in large construction machinery, etc. The acceptance of important facilities should be done well, and they can only be put into use after passing the inspection; And form a good pre-shift inspection system and Monday safety activity system, that is, the management department should organize all workers to carry out safety education every Monday, sum up the problems existing in safety last week, and make necessary disclosure on the safety key points and precautions this week.

8. Managers and construction workers at all levels should wear badges and identification helmets that can prove their identity; Abide by labor discipline, without illegal command and operation.

9. According to the regulations, all kinds of accidents should be reported and handled, the accident files should be complete, and the "three don't let go" should be done well.

1 1. Set up eye-catching safety slogans and safety warning signs at main construction sites, operating points, dangerous areas and main access points.

12, pay special attention to the protection of aerial work to prevent objects from hitting and falling. Use the "three treasures" (safety helmet, safety belt and safety net) with caution, and strengthen the fortification of "four entrances" (stairs, well crossings and reserved holes) and "borders" (scaffolding and foundation pits, etc.). ), and set up signs and night construction signals in the dangerous area at the scene.

13, pay special attention to the safety management of electricity consumption on the construction site, and strictly follow the requirements of specifications and procedures. Use five-core cable, iron distribution box and leakage protection device. Implement "one machine and one brake" and "one machine and one protection" and lock the distribution switch box. Users of mobile electric tools should wear insulating shoes and gloves, and use 36V safe voltage lighting. Therefore, the safety protection of construction electricity is stereotyped and instrumentalized.

14, sloping the construction site as required, setting up enclosures around it, and setting up sentries and checkpoints for external passages to ensure site safety.
