High-level pool, water supply main pipeline and water receiving pipe network connecting structure and construction method

Abstract

The invention relates to a high-level pool, a water supply main pipeline and water receiving pipe network connecting structure and a construction method. The high-level pool includes a pool main body,a water holding chamber is formed inside the pool main body, the outer wall of the pool main body is provided with an overflow pipe, the top end of the overflow pipe penetrates through the side wallof the pool main body and extends to the upper part of the water holding chamber, a waste canal is arranged on the outer side of the pool main body, the bottom end of the overflow pipe is connected tothe waste canal, the lower part of the pool main body is provided with a first water conveying pipe and a second water conveying pipe, one end of the first water conveying pipe and one end of the second water conveying pipe are in communication with the water holding chamber, the other end of the first water conveying pipe is used for being connected to a water supply main pipeline in an on-off manner, the other end of the second water conveying pipe is used for being connected to a water receiving pipe network in an on-off manner, and the height of the ground line of the pool main body is larger than the height of the ground line of the water receiving pipe network. The high-level pool, the connecting structure and the construction method solve the technical problems that when long-distance water conveying form the water supply main pipeline to the water receiving pipe network is carried out, the conveying difficulty is large, the failure rate is high, and the running cost is high.

Description

technical field [0001] The invention relates to the technical field of water delivery engineering, in particular to a connection structure and construction method of a high-level pool, a main water supply line and a water receiving pipe network. Background technique [0002] The long-distance water transmission and supply project is a huge system project to solve the problem of water shortage in the region. It is generally composed of three parts: the main project of the main canal, the supporting water supply project between the water diversion of the main canal and the entrance of the urban water plant, and the pipe network project of the urban water plant. . The supporting water supply project is connected to the main canal at the top and the urban pipe network at the bottom, and is responsible for the task of water delivery connecting the preceding and the following. The pipeline design of water supply supporting projects directly affects the safety and economy of water...

AI Technical Summary

Problems solved by technology

[0003] If the water receiving plant does not communicate properly with the main water supply management party, there may be a problem of insufficient design water level entering the plant, resulting in an increase in operating costs in the future

If there is only one water pipeline, the safety of the water pipeline operation will be more prominent, especially when the water receiving area is far away from the main water supply line, the distance to lay the pipeline is long, and when a failure or maintenance occurs during the transportation process, it will immediately face a shutdown The water dilemma is not convenient for the operation and management of water supply supporting projects

[0004] For the long-distance water delivery from the main water supply line to the water receiving pipe network in the related technology, there is no effective solution to the problems of difficult delivery, high failure rate, and high operating cost.
