Embodiment Construction

[0043] The following is attached Figure 1-5 The application is described in further detail.

[0044] The embodiment of the application discloses a foundation pit support structure. refer to figure 1 , a support structure for a foundation pit includes a plurality of baffles 1 , and all the baffles 1 are arranged end-to-end in sequence along the circumference of the foundation pit 2 on the inner sidewall of the foundation pit 2 . In this embodiment, the baffle plate 1 is a steel plate, and the cross-section of the steel plate is in the shape of "J" to improve the strength of the steel plate. The length direction of each baffle plate 1 is arranged along the depth direction of the foundation pit 2 , and the lower end of each steel plate is inserted in the bottom of the foundation pit 2 .

[0045] refer to figure 1 with figure 2 A plurality of connecting rods 3 are connected between each baffle plate 1 and the inner side wall of the foundation pit 2, and all the connecting r...

Abstract

The invention discloses a foundation pit supporting structure and a construction method thereof. The foundation pit supporting structure comprises a plurality of baffles arranged on the inner side wall of a foundation pit, wherein all the baffles are sequentially arranged in the circumferential direction of the foundation pit, and a plurality of connecting rods are connected between each baffle and the inner side wall of the foundation pit; a connecting hole penetrates the position, located on each connecting rod, of each baffle in the thickness direction of the baffle, a mounting hole is formed in the position, located on each connecting hole, of the foundation pit, and one end of each connecting rod is inserted into the corresponding mounting hole through the corresponding connecting hole; an abutting rod used for abutting against the inner side wall of each mounting hole is rotationally arranged at the end, located in the mounting hole, of the corresponding connecting rod, and a driving assembly used for driving each abutting rod to rotate is arranged between the abutting rod and the corresponding connecting rod; and an abutting block abutting against the side, away from the corresponding mounting hole, of each baffle is arranged at the end, away from the corresponding abutting rod, of each connecting rod. After construction in the foundation pit is completed, constructors disassemble the connecting rods, and then the baffles can be disassembled, so that the baffles can be repeatedly used, and the construction cost can be reduced.

Description

technical field [0001] The present application relates to the technical field of foundation pit construction, in particular to a foundation pit support structure and a construction method thereof. Background technique [0002] The foundation pit is an earth pit excavated at the foundation design position according to the base level and foundation plane size, and is used for the construction of the foundation of the building or the construction of the underground building. [0003] During foundation pit excavation, it is generally necessary to build a support structure to reduce the risk of accidents such as foundation pit collapse. Commonly used foundation pit support structures include row pile support, underground diaphragm wall support, reinforced concrete internal support and so on. [0004] In view of the related technologies mentioned above, the inventor believes that the structures such as row pile support, underground diaphragm wall support, and reinforced concrete ...
