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. The supporting structure comprises a first supporting bottom plate arranged on one side of a tunnel wall, two worms are symmetrically arranged on the side wall of the first supporting bottom plate, the worms are in threaded connection with the side wall of the first supporting bottomplate, multiple universal wheels are arranged at the bottom ends of the worms, a motor is fixedly arranged on the side wall of the first supporting bottom plate and located between the two worms, thebottom ends of second rotating rods are fixedly connected with the output end of the motor, and the second rotating rods are connected with the worms on the two sides thereof through transmission assemblies. According to the supporting structure, on one hand, the universal wheels make contact with the ground, and an anti-skid bottom plate is separated from the ground, and the whole structure conveniently moves through rolling of the universal wheels; and on the other hand, the anti-skid bottom plate makes contact with the ground, so that the stability of the whole supporting structure is enhanced; and the supporting structure is suitable for supporting walls with different inclination degrees, the adaptability is high, and the structure is scientific and reasonable.

Description

Technical field[0001]The invention belongs to the technical field of foundation pit support and relates to a foundation pit support structure with a tunnel on the side wall of the foundation pit.Background technique[0002]The foundation pit support project is a temporary project. The designed safety reserve can be relatively small, but it is related to the region. The geological conditions of different regions have different characteristics. The foundation pit support project is also geotechnical engineering, structural engineering and construction The subject of technology intersecting is a systematic engineering that interacts with multiple complex factors. It is a comprehensive technical subject to be developed theoretically. Due to the high cost of foundation pit support engineering and the large number of starts, it is the focus of competition among construction units. Due to the complexity of the technology, the wide range of changes, the number of changing factors, and the fre...

Problems solved by technology

[0004] The purpose of the present invention is to provide a foundation pit support structure with a tunnel on the side wall of the foundation pit, to solve the problems in the prior art: the current support structure design is unreasonable and too simple, and the initial support structure is completed After construction, the stability of the entire structure is not good, and there is a lot of inconvenience in the moving process after disassembly and assembly in the later stage. It is impossible to adjust the angle of the supporting wall panels according to the actual inclination of the tunnel wall, and the overall supporting quality is not good. To upgrade, there are certain security risks
