Safety supervision of deep foundation pit

1, safety preparation stage before construction:

1) Before the survey, the current situation of buildings, structures, roads and underground pipelines near the deep pit and the construction of adjacent construction projects in the same period should be investigated, and the survey data should be provided to the design, construction, monitoring and supervision units.

2) The scope of preliminary investigation starts from the edge of the foundation pit, and the scope standard is 3 times of the excavation depth of the foundation pit.

3) Design, construction, supervision, municipal administration, public power supply, communication, monitoring and other related units. Introduce the design, construction scheme and possible impact of construction, solicit opinions from relevant units, and further inspect, monitor, take photos or video the adjacent buildings, structures, roads and underground pipelines that may be affected. Set up signs and make records.

4) Review the construction scheme, and the construction enterprise shall organize an expert group of not less than 5 people to demonstrate and review the prepared safety special construction scheme.

5) Select the survey, design, construction, supervision and monitoring units of deep foundation pit engineering according to the contract management regulations of this Municipality, and do not split the contracted projects.

2. Safety management in the construction stage:

1) During the construction of deep foundation pit, the construction organization design or construction scheme should be worked out according to the design documents and requirements and in combination with the actual situation of the project. In addition to the conventional provisions, the construction organization design or construction plan should also include environmental protection measures, monitoring measures and emergency rescue measures.

2) The construction organization design or construction scheme shall be examined and approved according to the prescribed procedures. The approved construction organization design and construction scheme shall not be changed at will. If it is really necessary to modify it, it shall be approved by the original approval unit and approved by the original design unit.

3) The construction unit of deep foundation pit engineering should strengthen the quality and safety management and technical management procedures of the construction site, carry out the construction according to the approved construction organization design, and monitor the surrounding environment of the construction site. The construction site should be designed according to the deep foundation pit, and the construction site should be equipped with emergency rescue equipment and personnel.

4) After foundation pit excavation, fences should be set around the foundation pit for safety protection. Earthwork should not be piled up around the foundation pit, and it should be cleared away in time. Construction safety passages and drainage measures should be laid around the foundation pit.

5) During foundation pit operation, the construction unit shall determine the climbing facilities and special passages in the construction scheme, and the workers shall not climb the cave walls.

6) During foundation pit operation, the construction unit shall designate a special person to command and supervise. When displacement, cracking and leakage occur, the work should be stopped immediately and the workers should be evacuated from the job site. The operation can only be started after the danger is eliminated.

7) For deep foundation pits, especially soil slopes and bedding slopes with poor stability, the induced factors such as rainy season construction should be fully considered in the construction scheme, and pre-plan measures should be put forward.

8) After the foundation pit excavation is completed, the construction unit shall carry out underground structure construction in time, and it is forbidden to expose the foundation pit for a long time.
