Example Embodiment

[0045] Example 2:

[0046] The present disclosure provides an assembly method of a telescopic steel tube based on the above-described one-described tunnel contact passage, including the following procedure:

[0047] The construction process of the overall tube is as follows:

[0048] (1) Before the tube is installed, carry the carrier extension

[0049] Prior to the installation of the tube, the rectangular carrier and the curved carrier plate extended by pulling the arcuate carrier and the rectangular carrier plate, and the outer dimensions of the tube sheet were extended to the concrete preform. The top steel pipe is fixed in the force steel pipe through the limit bolt, and the PVC plastic plate is attached to the outside of the bottom carrier plate and the waterproof sealing strip is attached around the bottom carrier, which can prevent the bottom carrier sliding from the slurry and post-steel tubes. Difficulties such as difficulties.

[0050] It should be noted that the bottom...

Abstract

The disclosure relates to a telescopic steel pipe piece and an installation method for the construction of a tunnel connecting passage, which belong to the technical field of rail transit engineering. The steel pipe piece includes a rectangular bottom plate with an arc-shaped surface. Both ends in the width direction are connected to the first side plate, a second side plate perpendicular to the first side plate is provided in the length direction of the rectangular bottom plate, and a skeleton is arranged above the rectangular bottom plate, and the skeleton is within the length and width of the rectangular bottom plate. Several stressed steel pipes are arranged in each direction, and the first side plate and the second side plate are provided with jacking steel pipes, and the jacking steel pipes are slidably fixed on the stressed steel pipes. 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 a telescopic steel pipe piece and an installation method for the construction of a tunnel connecting passage. 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 com...
