Tunnel escape pipeline

Abstract

The embodiment of the invention provides a tunnel escape pipeline, and relates to the field of tunnel construction. The tunnel escape pipeline comprises a foundation pipe body, at least one telescopicpipe body, first moving devices and second moving devices arranged on reservation sections, wherein the foundation pipe body comprises a first end and a second end; the telescopic pipe bodies sleevethe second end of the foundation pipe body and extend and contract relative to the second end of the foundation pipe body as a whole; each telescopic pipe body comprises an extension section and the reservation section; each telescopic pipe body is extended and contracted relative to the adjacent telescopic pipe bodies, and the reservation sections of the telescopic pipe bodies are retained outside pipe bodies accommodating the telescopic pipe bodies when the telescopic pipe bodies are in a contracted state; the first moving devices are installed on the foundation pipe body for supporting andmoving the foundation pipe body; and the second moving devices are arranged on each reservation section for supporting the telescopic pipe bodies in which the reservation sections are located and fordriving the extension sections on the telescopic pipe bodies to achieve extension and contraction. The tunnel escape pipeline improves the handling and installation efficiency of the tunnel escape pipeline, ensures the installation quality, and can be applicable to different levels of surrounding rock construction sections.

Description

Technical field [0001] The invention relates to the field of tunnel construction, in particular to a tunnel escape pipeline. Background technique [0002] With the rapid development of railways and highways, the scale and difficulty of tunnel construction have become greater and greater, and tunnel collapse accidents have continued to occur. For this reason, escape routes must be set up during tunnel construction. However, due to the limited construction work in the tunnel, the transportation and installation of the tunnel escape pipeline basically rely on manual operation. The escape pipeline is relatively heavy, and the efficiency is very low due to manual handling and installation. Therefore, it is necessary to develop a tunnel escape pipeline that can greatly improve handling efficiency and installation accuracy. Summary of the invention [0003] The present application provides a tunnel escape pipeline, which can avoid all manual handling and installation, speed up the hand...
