Problems solved by technology

[0006] The above-mentioned structures all use large-diameter segments, but because the urban underground pipelines are very complicated now, the tunnels constructed by the small-diameter segments are more suitable for complex urban underground pipelines, and the above-mentioned existing technologies are used for the construction of small-diameter segments. It is very time-consuming, and it is difficult to grasp the accuracy, and water seepage may occur in the shield

Abstract

The invention relates to the technical field of tunnel construction, in particular to a device for soft soil foundation shield tunnel construction. The device for soft soil foundation shield tunnel construction comprises a shield body, a cleaning system and a segment assembling system, wherein the cleaning system is arranged in the shield body, and the segment assembling system is connected with the tail of the shield body; the segment assembling system is connected with the tail of the shield body through a mounting disc and comprises a pushing part and a clamping part, the pushing part is fixedly connected with the mounting disc, the clamping part is connected with the free movable end of the pushing part, and the clamping part clamps segments for splicing and using. According to the device for soft soil foundation shield tunnel construction and an using method, the problems that in the specific using process in the prior art, an existing urban underground pipeline is very complex, large-diameter pipe pieces are not suitable for being installed in tunnels with complex and changeable lines, small-diameter pipe piece construction in the prior art consumes much time, and the accuracy is difficult to grasp are solved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a device for construction of a shield tunnel on a soft soil foundation and a method for using it. Background technique [0002] With the continuous development of urban construction, more and more municipal pipelines are buried underground. Generally, the installation of underground pipelines is basically done by burying. However, for large-diameter urban water diversion steel pipes, due to the large diameter of the steel pipes, it is inconvenient to bury them. In addition, there are many urban buildings. The demolition requires a large amount of work, so the construction is difficult and costly. [0003] Pipeline installation in shield tunnels is often encountered in water conservancy projects, mining projects, petroleum, and nuclear power pipeline projects. However, for some heavy-duty pipelines with large diameters, due to the large volume of the pipeline and the ...
