Long-distance large-pipe diameter underground water conveying main pipe system

Abstract

The invention discloses a long-distance large-pipe diameter underground water conveying main pipe system. The system comprises two water conveying main pipes and a plurality of communication pipes, wherein the water conveying main pipes are arranged in parallel, the plurality of communication pipes are arranged between the two water conveying main pipes in a communication mode, communication valves which are used for cutting of water flow are arranged on the communication pipes, valves which are used for cutting off water flow are arranged on the water conveying main pipes and are arranged respectively on two sides of a position at which the communication pipes and the water conveying main pipes are connected, and a plurality of communication section working wells, tee joint working wells and multidirectional transfer wells are arranged on the two water conveying main pipes. According to the system, when any section of the water conveying main pipes fails, accident water flow can still pass through the pipes, the operation of the whole water conveying main pipe system is safe, reliable, economic and effective; at the same time, by the aid of working wells on which various parts are arranged, workers can perform unified management and maintenance on the water conveying main pipes conveniently, the space is saved, the workload is reduced, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a water supply pipeline system, in particular to a long-distance and large-diameter underground water main pipeline system. Background technique [0002] With the development of our country's economy, more and more cities have begun to build long-distance large-scale water delivery projects. In long-distance and large-diameter water delivery projects, it is usually necessary to set vent valves, exhaust valves, manholes and other components and multiple working wells on the water delivery main pipe. In the current water delivery project, the water delivery main pipe The setting positions of each component are scattered, and more maintenance wells need to be set up, which is not conducive to the unified management and maintenance of the water pipeline, and also takes up more space and increases the project cost. [0003] In addition, most of the existing water delivery systems are single-pipe delivery. If any section of the main...

Problems solved by technology

In long-distance and large-diameter water delivery projects, it is usually necessary to set vent valves, exhaust valves, manholes and other components and multiple working wells on the water delivery main pipe. In the current water delivery project, the water delivery main pipe The installation positions of each component are scattered, and more maintenance wells need to be installed, which is not conducive to the unified management and maintenance of water pipelines, and also takes up more space and increases the project cost

[0003] In addition, most of the existing water delivery systems are single-pipe delivery. If any section of the main water delivery pipe fails, it will inevitably affect the work of the entire water supply system.
