Supporting cross beam mounting structure of municipal shield tunnel

Abstract

The invention discloses a supporting cross beam mounting structure of a municipal shield tunnel. The supporting cross beam mounting structure comprises a top ring, a plurality of supporting rods and aplurality of abutting bolts, wherein a plurality of uniformly distributed notches are formed in the periphery of the top ring; limiting grooves are formed in the two sides of the notches; abutting screw holes penetrating through the top ring are formed in the bottoms of the notches; limiting blocks are arranged on the two sides of the supporting rods; each notch in the plurality of notches is penetrated by one supporting rod; the plurality of notches are positioned in the same plane; the plane is perpendicular to the supporting rods; the limiting blocks are limited in the limiting grooves; one abutting bolt is arranged in the abutting screw holes in a matched mode; the abutting bolts abut against the supporting rods; and the plurality of supporting rods are parallel to one another. Compared with the prior art, when the supporting cross beam mounting structure is disassembled and assembled, only the abutting bolts need to be screwed, the disassembling and assembling process is simple and rapid, and the construction time can be effectively shortened; and the first bearing rod and the second bearing rod can remarkably enhance the supporting effect on the prefabricated concrete pipe.

Description

technical field [0001] The invention relates to a supporting beam structure, in particular to a supporting beam structure of a municipal shield tunnel. Background technique [0002] The municipal shield tunnel is built underground in the city and is used as a tunnel for laying underground pipelines of various municipal facilities. Due to the need to further develop industry and improve residents' cultural and living conditions in cities, there are more and more underground pipelines for municipal facilities, such as power supply, tap water, sewage, heating, hot water, gas, communication and power supply. The development of the pipeline system requires the construction of a large number of municipal tunnels in order to fundamentally solve the problem of the operation level of the underground pipeline system of various municipal facilities. When arranging underground passages, pipelines, and cables, there should be a strict sequence and system to avoid excavating streets and ...

AI Technical Summary

Problems solved by technology

[0003] Existing thermal shield tunnels are usually equipped with brackets that can penetrate into various pipelines. Usually, the existing fixed brackets have a relatively simple structure, and are directly formed by pouring concrete with the tunnel segments. When adjusting the position of the support, it is difficult to disassemble and assemble the support, which constitutes a great obstacle to the construction of the tunnel and the maintenance of the tunnel
