Abstract

The invention discloses a shield tunneling machine underground diaphragm wall penetrating construction device and a construction method thereof, and relates to the technical field of pipeline construction. The device comprises a propelling distance adjusting structure, a reaming guide structure and movable guide reaming structures, the top end of the propelling distance adjusting structure is fixedly connected with the reaming guide structure used for four-direction synchronous expansion output, one end of the four ends of the reaming guide structure is provided with the movable guide reaming structures, and the movable guide reaming structures are used for crushing soil. According to the device, through the cooperative design of a guide structure, the reaming guide structure and the movable guide reaming structure, the device can conveniently and automatically complete power output of adaptive positions on the positions needing reaming, so that convenient space expansion can be conducted on the pipe descending construction positions, the construction convenience is greatly improved, through the design of the reaming guide structure, the device can conveniently finish output of four-direction synchronous derivation, and the convenience and the output efficiency in the lower pipe reaming process are greatly improved.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a construction device and a construction method for a shield tunneling machine to pass through a ground connection wall. Background technique [0002] With the rapid development of society, the shield machine has made a lot of contributions in the construction process of the underground connection wall. In order to facilitate the construction of the underground connection wall, it is necessary to expand and break the blocked soil, so the corresponding construction device is required, but , the existing construction device applied to soil expansion and breaking has the following problems during use: [0003] 1. It is not convenient for multi-directional simultaneous expansion and breaking; [0004] 2. It is not convenient for automatic expansion and breaking, resulting in low overall efficiency. Contents of the invention [0005] The purpose of the present invent...
