Underground comprehensive pipe gallery structure and construction method thereof

Abstract

The invention relates to the technical field of underground engineering, in particular to an underground comprehensive pipe galley structure and a construction method thereof. The construction method includes the steps of laying a concrete cushion layer on a foundation pit bottom, laying a waterproof coiled material layer of a baseboard on the concrete cushion layer, laying a baseboard protecting layer on the waterproof coiled material layer of the baseboard, manufacturing a main pipe gallery body on the baseboard protecting layer, laying a waterproof coiled material layer of a sidewall on the outer surface of the sidewall of the main pipe gallery body, laying a waterproof coiled material layer of a top board on the outer surface of the top board of the main pipe gallery body, laying a polystyrene board protecting layer on the waterproof coiled material layer of the sidewall, and laying a concrete protecting layer on the waterproof coiled material layer of the top board. The underground comprehensive pipe gallery structure includes the main pipe gallery body, the outer bottom surface of the main pipe gallery body is successively provided with the baseboard protecting layer, the waterproof coiled material layer of the baseboard and the concrete cushion layer in a laid mode from top to bottom. The underground comprehensive pipe galley structure is conducive to reduction of water seepage circumstances inside the main pipe gallery body and prolongs the service life of underground comprehensive pipe galleries.

Description

technical field [0001] The invention relates to the technical field of underground engineering, in particular to an underground comprehensive pipe gallery structure and a construction method thereof. Background technique [0002] With the rapid development of urbanization across the country and the rapid increase of urban population, how to renovate old cities and improve the living environment of residents has been put on the agenda by local governments. Most of the old urban areas have problems such as narrow roads and old and missing infrastructure. Among them, the traditional direct-buried pipe network system is also constantly excavated, expanded, re-excavated, and re-expanded with the increase in population. The roads are blocked all the year round, the network is disconnected, Power outages happen from time to time. In recent years, the construction of underground comprehensive pipe corridors has made it possible to completely solve the problem of the old urban pipe ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an underground comprehensive pipe gallery structure and its construction method to solve the problem in the prior art that the main body of the pipe gallery is buried under the soil layer, and the concrete structure of the main pipe gallery itself is often difficult to waterproof. , the interior of the main body of the pipe gallery is prone to water seepage technical problems
