Support frame used for foundation pit with arch type balanced beam structure

Abstract

The invention discloses a support frame used for a foundation pit with an arch type balanced beam structure. The support frame includes a foundation soil layer, a groove is formed in the foundation soil layer, a protection box is arranged in the groove, the upper end of the protection box is fixedly provided with a fixation block, the four side walls of the fixation block are fixedly provided withfixation boxes, one end of each fixation box is fixedly provided with an L-shaped plate, the upper ends of the four L-shaped plates are erected at the upper ends of the groove, the fixation block andthe lower ends of the four fixation boxes are jointly and fixedly provided with protection boxes, rotation devices are arranged in the protection boxes, adjustment devices are arranged in the fixation boxes, the rotation devices are connected with the adjustment devices, and the lower ends of the adjustment devices are provided with connection rods. The support frame solves the problems that theinstallation efficiency and the disassembly efficiency of the support frame are low, the speed is low, and much time is consumed, meanwhile the problems that stable fixation can not be achieved when the support frame is used in foundation pits different in size, the stability of the support frame is improved, and meanwhile the work efficiency is improved.

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
