Embodiment 2

[0044] An embodiment of the present disclosure provides an assembly method based on the above-mentioned self-shrinkable steel pipe sheet, the method includes the following process:

[0045] The overall construction process of the segment is as follows:

[0046] (1) Before the segment is installed, the bearing plate is extended

[0047] Before the segment is installed, the jack is pressurized by controlling the hydraulic system of the segment, so that the rectangular bearing plate and the arc bearing plate are stretched out, and the external dimension of the stretched segment is consistent with the concrete prefabricated segment. At the same time, a PVC plastic plate is installed on the outside of the bottom bearing plate and a waterproof sealing strip is pasted around it, which can prevent problems such as slurry leakage at the slidable part of the bottom bearing plate and difficulty in removing the steel pipe sheet later.

[0048] What needs to be explained is that the botto...

Abstract

The disclosure relates to an automatically shrinkable steel pipe sheet and an assembly method, which belong to the technical field of rail transit engineering. The steel pipe sheet includes a rectangular bottom plate with an arc-shaped surface, and the rectangular bottom plate can be stretched in the width direction. The two ends are connected to the first side plate, and the inner side of the rectangular bottom plate is provided with a first telescopic mechanism that is connected with the first side plate and controls the expansion and contraction of the rectangular bottom plate; The second side plate, the second side plate is connected with the second telescopic mechanism arranged on the inner side of the rectangular bottom plate, and a suspension rod is arranged on the rectangular bottom plate. The disclosed steel pipe piece solves the problem that the section section of the connecting channel of the shield tunnel is difficult to disassemble and cannot be reused.

Description

technical field [0001] The disclosure belongs to the field of rail transit engineering, and in particular relates to an automatically shrinkable steel pipe sheet and an assembly method. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Shield or TBM tunnels are mostly supported by prefabricated concrete segments, and the installed segments need to be removed first during the construction of the tunnel connecting passage. At present, the demolition of presupported concrete segments at the communication channel is mostly done by pneumatic picks. The vibration generated by the pneumatic picks will affect the stability of the existing structure, and the workload of the pneumatic picks is large, the construction speed is slow, and the construction safety is poor. In order to facilitate the construction of the communication channel, some projects have us...
