Construction equipment for subway station deep foundation pit enclosure structure

Abstract

The invention belongs to the technical field of subway station deep foundation pit construction, and particularly relates to construction equipment for a subway station deep foundation pit enclosure structure. The construction equipment comprises a lifting mechanism, a guide rail frame, a base support, a base and a traction fixing mechanism. According to the construction equipment, a third motor and a fourth motor can control a supporting sliding block to slide in a sliding frame in the front-back direction and the left-right direction, a wall body component can be placed in a supporting groove in a sliding supporting block when being hoisted and inserted into a hook groove, that is, the wall body component can be adjusted in the front-back direction and the left-right direction by controlling sliding of the sliding supporting block, the wall body component can be conveniently inserted into a clamping groove in a supporting sliding plate to be aligned with the wall body component on the lower side, and the subsequent welding effect is guaranteed. According to the construction equipment, hoisting equipment does not need to participate in the subsequent inserting work of the wall body component, the hoisting equipment can be prepared to transfer the next wall body component, and therefore the working efficiency is improved through the design; and meanwhile, the damage rate of the hoisting equipment is reduced, and the service life of the hoisting equipment is prolonged.

Description

[0001] Technical field [0002] The invention belongs to the technical field of subway station deep foundation pit construction, and in particular relates to construction equipment for a deep foundation pit enclosure structure of a subway station. Background technique [0003] The construction of the deep foundation pit enclosure structure of the subway station often adopts the TAD construction method, also known as the construction method of the canal-cut assembled underground diaphragm wall, which uses the canal-cut cement-soil diaphragm wall to implant reinforced concrete prefabricated components to form an assembled underground diaphragm wall a construction technique. Compared with the traditional underground continuous wall manufacturing process, the TAD construction method has the advantages of less space, strong adaptability, short construction period, and environmental protection. During construction, the ground is first cut and excavated with the TRD construction mac...

AI Technical Summary

Problems solved by technology

[0004] However, this construction method has the following problems: first, the wall components need to be hoisted all the time by lifting equipment during the construction process, and the loss of the lifting equipment is relatively large

Second, the upper and lower wall components are welded by electric welding. After the first wall component is inserted, the wall component needs to be fixed before the second wall component can be lifted. The first section of the wall is supported on the frame by the support rods. After the welding is completed, the support rods are artificially removed. This process is dangerous and the effect is low.
