Externally-hung type underground comprehensive pipe rack

Abstract

The present invention provides an externally-mounted underground comprehensive pipe gallery, including the pipe gallery, which is characterized in that the gas pipe trench or / and rainwater box culvert and the pipe gallery are superimposed to form a whole, arranged on the upper part of the pipe gallery, and the pipe gallery is provided with hoisting openings, ventilation At the opening, the gas pipe ditch or / and the rainwater tank culvert are installed on the side of the hoisting opening and the ventilation opening in the form of partial hanging. The invention can effectively integrate the rainwater and gas pipelines into the comprehensive pipeline gallery, ensure the safe operation of the underground pipelines, and realize the purpose of rationally developing underground space resources and being economical and effective.

Description

technical field [0001] The invention belongs to an externally-mounted underground comprehensive pipe gallery involved in the urban underground comprehensive pipe gallery project, in particular to a layout form of a comprehensive pipe gallery applied to the entry corridor of rainwater pipelines and gas pipelines. Background technique [0002] With the growth of population and the continuous development of social economy in our country, the number of pipelines of various types of water supply, drainage, gas, and electricity is increasing, which is accompanied by the planning and layout of various municipal pipelines. Due to the lack of unified coordination and planning, the phenomenon of repeated excavation and filling of roads often occurs, which seriously affects the orderly operation of the city and the daily life of residents. The comprehensive pipe gallery is a structure built underground in the city to accommodate two or more types of urban engineering pipelines. The con...

Problems solved by technology

[0004] However, when the rainwater pipes enter the pipe gallery, there are not only unfavorable factors such as increased pipeline burial and difficulty in the layout of rainwater inspection wells, but also occupy valuable underground space, and the project cost is high

[0005] Incorporating municipal gas pipelines into comprehensive pipe corridors can reduce the accidents of such pipelines being cut off during urban road construction. However, according to national regulations, gas pipelines included in comprehensive pipe corridors must be installed in a single cabin, and a series of monitoring and alarm equipment must be added at the same time. It is necessary to take certain safety precautions, and the project cost will increase significantly. At the same time, higher requirements are put forward for the safety and management of the utility gallery

[0006] In recent years, there have been only a small number of design cases in China where rainwater and gas pipelines have been integrated into integrated pipe corridors. The research on the above two types of pipelines into corridors is still in its infancy, and there are few engineering experiences that can be used for reference and promotion.
