Underground utility tunnel and construction method thereof

Abstract

The invention relates to an underground utility tunnel and a construction method thereof. The underground utility tunnel comprises a plurality of bottom slab members, a plurality of wall members, insertion rods, and a plurality of roof members, wherein every two adjacent bottom slab members are fastened and connected through penetrating connecting bars; the wall members and the bottom slab members are connected through the insertion rods, and the tops of the insertion rods stretch out of the top ends of the wall members; every two adjacent roof members are fastened and connected through penetrating connecting bars; and the insertion rods are sleeved with the roof members, and the roof members are arranged on the wall members correspondingly, so that the corresponding underground utility tunnel is formed by the bottom slab members, the wall members and the roof members in an enclosed mode. The underground utility tunnel is decomposed into modules, then prefabricated splicing work is conducted, the problem that large-size members cannot be lifted or transported is solved, rigid connection between the members is achieved through the insertion rods, tensioning connection between the members is achieved through the connecting bars, and thus, the bearing capacity and durability of a structure can be guaranteed.

Description

technical field [0001] The invention relates to a prefabricated assembly structure of an underground comprehensive pipe gallery, in particular to an underground comprehensive pipe gallery and a construction method thereof. Background technique [0002] The underground comprehensive pipeline corridor, also known as "common ditch" or "common pipeline", is the comprehensive corridor of underground urban pipelines. Build a tunnel space underground in the city, integrate various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage, etc., and set up special inspection ports, hoisting ports and monitoring systems, and implement unified planning, unified design, and unified Construction and management are the important infrastructure and "lifeline" to ensure the operation of the city. It is a municipal public facility that implements the same planning, design, construction and maintenance, and is built underground for laying municipal pu...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the defects of the prior art, provide an underground comprehensive pipe gallery structure and its construction method, and solve the problem that traditional prefabrication processing cannot be applied to multi-chamber prefabrication construction due to its own weight and large volume
