Fabricated prefabricated comprehensive pipe gallery and mounting method

Abstract

The invention provides a fabricated prefabricated comprehensive pipe gallery and a mounting method. The fabricated prefabricated comprehensive pipe gallery is formed by assembling a plurality of prefabricated pipe joints; each prefabricated pipe joint comprises a bottom plate, a top plate, a first side plate and a second side plate; connecting cavities are formed in the connecting positions of every two of the bottom plates, the top plates, the first side plates and the second side plates; a connecting part and a plugging device are arranged in each connecting cavity; an outer vertical plate which is bent downwards is arranged at the outer side, forming a connecting cavity structure, of the top plate, and an outer vertical plate which is bent upwards is arranged at the outer side, forminga connecting cavity structure, of the bottom plate; an expansion joint is formed between the outer vertical plate on the top plate and the outer vertical plate on the bottom plate; and the expansion joint is in water-stop sealing connection. According to the fabricated prefabricated comprehensive pipe gallery and the mounting method, the structure is reasonable, assembly is convenient and fast, connection is stable, waterproof and reliable, the applicability is extremely high, the steps of the construction method are simple, and the operability is extremely high.

Description

technical field [0001] The invention relates to the technical field of underground engineering, in particular to an assembled prefabricated comprehensive pipe gallery and an installation method. Background technique [0002] Comprehensive pipe gallery is the comprehensive corridor of underground urban pipelines, that is, to build a tunnel space underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., with special inspection ports and hoisting ports And monitoring system, the implementation of unified planning, unified design, unified construction and management, is an important infrastructure to ensure the operation of the city. [0003] There are two main types of comprehensive pipe corridors, namely cast-in-place concrete comprehensive pipe corridors and prefabricated assembled concrete comprehensive pipe corridors. The first developed is the cast-in-place concrete integrated pipe galle...

AI Technical Summary

Problems solved by technology

The waterproof of the prefabricated integrated pipe gallery is prone to failure. The main reasons for the failure come from two aspects. One is the leakage and water seepage caused by the cracks in the main structure of the self-waterproofing. damage caused by water leakage

The most important problems are as follows: the joints are not waterproof, the concrete self-waterproofing is not up to the standard, the life of the waterproof material outside the structure is greatly different from that of the main structure, and it is easy to fail, and the weak parts such as the bottom plate and the top plate are easy to leak, etc.

[0005] In addition, the construction of the joints of the prefabricated integrated pipe gallery generally requires the setting of pouring mold cavities to complete the pouring of concrete. After the construction is completed, it needs to be dismantled, which increases the construction process and reduces the construction efficiency.
