Deep foundation pit supporting structure and installation method

Abstract

The invention relates to a deep foundation pit supporting structure. The deep foundation pit supporting structure comprises a deep foundation pit, fender post structures, a supporting structure, an anchoring structure, fixed beam structures and movable beam structures. A concrete pouring layer is poured at the bottom of the deep foundation pit. A pressing plate is fixedly installed above the concrete pouring layer. The fender post structures are arranged at the bottom of the deep foundation pit and the two sides of the inner wall of the deep foundation pit. Holes of the same size are formed in the two ends of the bottom pressing plate. A deep foundation pit supporting anchor rod anchors the pressing plate through the holes of the bottom pressing plate. The middle of the bottom pressing plate is connected with one end of a fixed support. The other end of the fixed support penetrates through the two layers of fixed beam structures and is connected with the two layers of fixed beam structures. Concave grooves are formed in the two ends of each fixed beam structure. The concave grooves in the two ends of each fixed beam structure are connected with one sides of the movable beams at the two ends correspondingly. The other sides of the movable beams are connected with a force bearing plate. Grooves are symmetrically formed in the two ends of the force bearing plate. Bolts penetrate through the force bearing plate and a spring structure and then are connected with supporting plates on the two sides of the inner wall of the deep foundation pit for fixation. The deep foundation pit supporting structure can be repeatedly used, installation is convenient, and stability is high.

Description

technical field [0001] The invention belongs to the technical field of deep foundation pit support, and in particular relates to a deep foundation pit support structure and an installation method. Background technique [0002] Construction accidents in deep foundation pit engineering occur frequently, and once an accident occurs, it is very easy to cause mass death and injury, and the consequences are quite serious. The main reason is that the construction plan and various safety precautions during the construction process are not in place. According to the requirements of the relevant national regulations, the construction of deep foundation pit engineering must prepare detailed supervision rules to clarify the technical requirements of deep foundation pit engineering and the inspection points of the construction site. Deep foundation pit support refers to the support, reinforcement and protection measures adopted for the side wall of deep foundation pit and the surrounding...

Problems solved by technology

The disadvantage of this method is that once the bracket becomes loose, it will not be able to support the steel plate welded on it, and there will be instability in the actual reference, and the support of deep foundation pits in this way is low in work efficiency , and waste material
