Foundation pit supporting structure and method

Abstract

The invention relates to a foundation pit supporting structure and method. The foundation pit supporting structure comprises a plurality of pile rows, wherein the lower ends of the pile rows can be inserted into a soil layer below a foundation pit, each pile row is composed of a plurality of tubular piles which are vertically arranged side by side, and every two adjacent pile rows are fixed through a vertical connecting plate so as to arrange the plurality of pile rows in rows; and a notch is formed between the lower end of the connecting plate and the bottom surface of the foundation pit, a rotating rod is rotationally arranged on the upper portion of the notch, one end of the rotating rod can extend into the soil layer on the side wall of the foundation pit to form an unloading platform,and an inclined strut component is arranged between the other end of the rotating rod and the upper ends of the pile rows to transmit torque.

Description

technical field [0001] The disclosure belongs to the technical field of foundation pit support, and in particular relates to a foundation pit support structure and method. Background technique [0002] In foundation pit engineering, the most common support method is to use support structures, such as anchor support structures, support support structures and cantilever support structures. [0003] The inventors have learned that the force-bearing forms of these retaining structures rely on their own strength to resist the lateral force of the soil, and their supporting capacity depends on the strength of the structure itself, especially the cantilever structure, but for structures and soil The interaction was not exploited further. In addition, in the foundation pit project, the drainage system needs to be set up separately. In case of heavy rain or drainage failure, accidents such as foundation pit instability are prone to occur. Contents of the invention [0004] The pu...
