A Flood Storage Urban Underground Comprehensive Pipe Gallery

Abstract

The invention discloses a flood storage type urban underground comprehensive pipe gallery, which includes a first maintenance pipe gallery, a second maintenance pipe gallery, a first extension pipe gallery, and a second extension pipe gallery. The maintenance pipe gallery is divided into the upper water storage chamber and the first partition of the lower water storage chamber. The first partition is fixed with a vertical upward overflow pipe. The outlet and the upper part of the overflow pipe are screwed with a plug; a flexible connection pipe fitting is installed between the first maintenance pipe gallery and the second maintenance pipe gallery to connect the lower water storage chamber with the sewage discharge chamber. The beneficial effects are: the lower water storage chamber improves the daily drainage capacity of the sewage chamber, and the upper water storage chamber improves the drainage capacity of the sewage chamber during the flood season; the horizontal span of the single-section pipe gallery is reduced, so that the pipe gallery can be prefabricated in the factory and transported to On-site assembly and splicing, and flexible connections between adjacent pipe galleries can improve the seismic performance of the integrated pipe gallery, shorten the on-site construction period, and facilitate maintenance and replacement.

Description

technical field [0001] The invention relates to the technical field of comprehensive pipe gallery, in particular to a flood storage type urban underground comprehensive pipe gallery. Background technique [0002] The 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, hoisting ports and The monitoring system, which implements unified planning, unified design, unified construction and management, is an important infrastructure and "lifeline" to ensure the operation of the city. [0003] In recent years, during the flood season in major cities, it is easy to cause urban waterlogging due to heavy rain. The main reason is that the cross-sectional area of ​​the city's sewage pipes is fixed and cannot be adjusted, so that during heavy rains...

AI Technical Summary

Problems solved by technology

[0004] Although the existing comprehensive pipe gallery structure divides the pipe gallery into multiple functional areas, each functional area is independent of each other and cannot be dispatched between functional areas; and the existing comprehensive pipe gallery has a large span and requires on-site pouring Forming, the anti-seismic and anti-crack performance of the comprehensive pipe gallery is poor, the on-site construction period is long, and maintenance and replacement are difficult
