Foundation pit structure and construction technology thereof

Abstract

The invention relates to a foundation pit structure. The foundation pit structure comprises foundation pit bodies formed through slope excavation, each inclined inner wall of the foundation pit body is provided with a plurality of rows of inclined wall pile rods, inclined wall plates are attached to the inclined inner walls of the foundation pit bodies, the bottoms of the inclined wall plates abut against the corresponding rows of inclined wall pile rods, and each inclined wall plate is hinged to a plate supporting rod; and bottom face fixing rods are arranged at the ends, away from the connected inclined wall plates, of the plate supporting rods, bottom face blocks are arranged on the bottom faces of the foundation pit bodies, the bottom face fixing rods are detachably connected to the bottom face blocks, and the bottom face fixing rods are provided with plate supporting rod moving devices for driving the plate supporting rods to move towards the adjacent inclined inner walls of the foundation pit bodies. Even if the slopes of the inclined inner walls of different foundation pit bodies are different, the inclined wall plates and the plate supporting rods can be adaptively arranged, the applicability of foundation pit supporting is improved, the corresponding supporting structure of the foundation pit can be repeatedly used, waste is not prone to being generated, and the environment-friendly effect is achieved.

Description

Technical field [0001] The present application relates to the field of the foundation, particularly to a structure and a foundation construction process. Background technique [0002] Before the construction of the plant, such as our contract Deqing County Bluebird Deqing Lighting Appliance Co. and Huatai Textile Co. plant engineering, because it may put some heavy equipment in the plant, so the need for soil where the plant will be based excavation pit, and then enter the number of the piles in the pit bottom at the pit bottom after compaction, and then casting the same on a separate pile cap, so that the load-bearing pillar of the plant above the soil structure provided independent Cap , the structure of the plant above the soil so less prone to sedimentation. [0003] When carrying out the conventional excavation pit, the pit depth is not deep in the case, and surrounded by some space excavation grading may be employed, it is possible to reduce the set of the excavation, even ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the slope of each foundation pit excavation is different due to the limitation of the surrounding space and the difference in the depth of the foundation pit when grading and excavating the foundation pit, while the existing support It is difficult to adjust the angle of the structure, and there is a defect that the applicability of foundation pit support is poor
