Foundation pit supporting structure for foundation pit with tunnel on side wall

Abstract

The invention discloses a foundation pit supporting structure for a foundation pit with a tunnel on the side wall and belongs to the technical field of foundation pit construction. The structure comprises two moving seats; moving grooves are formed in the ends, close to each other, of the two moving seats; a same moving plate is slidably installed in the two moving grooves; first slide grooves areformed in the top of the two moving seats; first sliders are slidably installed in the two first slide grooves; inclined plates which are symmetrically arranged in an inclined mode are fixedly installed on the two first sliders; inclined seats are rotatably installed at the ends, away from each other, of the two inclined plates; supporting plates are fixedly installed at the ends, away from eachother, of the two inclined seats; supporting grooves are formed at the bottom ends of the two supporting plates; and supporting rods are slidably installed in the two supporting grooves. Through height adjustment of the supporting plates and extension of the two moving seats, the foundation pit supporting structure is applicable to foundation pits of different sizes, the limitation is reduced, theoperation is simple and application needs are satisfied.

Description

technical field [0001] The invention relates to the technical field of foundation pits, in particular to a foundation pit support structure with tunnels on the side walls of the foundation pit. Background technique [0002] The foundation pit support is to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit. The support, reinforcement and protection measures are adopted for the side wall of the foundation pit and the surrounding environment. It is suitable for the location where the surrounding field is open and there are no important buildings around At present, the common support structures for foundation pit construction include: row-pile support structures with bored piles or reinforced concrete slabs as the main body, underground diaphragm walls, cement-soil walls, deep-mixed cement-soil enclosure walls, high-pressure rotary grouting Pile, SMW construction method. [0003] The patent of CN108166506A disclose...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the foundation pit support structure in the prior art that needs to be reinforced by pouring concrete, and the position and angle cannot be adjusted after fixing, which has large limitations and cannot adapt to foundation pits of different sizes, which brings great inconvenience to the staff. Due to the difficulty of operation, it cannot meet the needs of use, and a foundation pit support structure with tunnels on the side wall of the foundation pit is proposed.
