Support frame for foundation pit with arched balance beam structure

Abstract

The invention discloses a supporting frame for a foundation pit with an arch-shaped balance beam structure, which comprises a foundation soil layer, a groove is arranged on the foundation soil layer, a protection box is arranged in the groove, and the upper end of the protection box A fixed block is fixed, and a fixed box is fixed on the four side walls of the fixed block. One end of the fixed box is fixed with an L-shaped plate, and the upper ends of the four L-shaped plates are set on the upper end of the groove. The lower ends of the fixed block and the four fixed boxes are jointly fixed with a protective box, the protective box is provided with a rotating device, and the fixed box is provided with an adjusting device, and the rotating device and the adjusting device are connected to each other. The lower end is provided with a connecting rod. The invention solves the problems of low efficiency, slow speed and time-consuming when installing and disassembling the support frame, and also solves the problem that the support frame cannot be stably fixed when using the support frame in foundation pits of different sizes, and improves the support frame. Stability, but also improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of support frames for foundation pits, in particular to a support frame for foundation pits with an arch balance beam structure. 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. Before excavation, the excavation plan should be determined according to the geological and hydrological data, combined with the conditions of the nearby buildings, and the waterproof and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to the relevant construction regulations. For those with deep excavation and nearby buildings, the foundation pit wall support method, shotcrete retaining wall method, and large foundation pit even adopt methods such as underground diaphragm wall and column-type bored pile ...

AI Technical Summary

Problems solved by technology

[0003] At present, foundation pits and support frames are often used during engineering construction. However, the existing support frames for foundation pits are simple in structure and poor in practicability, and the support frames cannot be put into use according to the size of the foundation pit, resulting in delays in project progress The efficiency is low, and at the same time, the support frame cannot be stably fixed during use, causing construction workers to be prone to danger when performing operations, and the existing support frame is inconvenient to install and disassemble. For this reason, we propose an arch balance The foundation pit of the beam structure uses a support frame to solve the above problems
