Novel drainage system for water conservancy project channel

Abstract

The invention relates to the technical field of drainage projects, and particularly relates to a novel drainage system for a water conservancy project channel. The novel drainage system comprises an urban drainage system and an auxiliary drainage system; the auxiliary drainage system comprises an urban drainage pipe network arranged in a city and a peripheral drainage pipe network arranged on the periphery of the city; the urban drainage pipe network comprises a center temporary water storage area arranged in the city and a water body arranged in the city; an underground drainage pipeline is connected between the center temporary water storage area and the water body; the peripheral drainage pipe network comprises a peripheral temporary water storage area arranged on the edge of the city and a reservoir arranged on the periphery; and a surface drainage pipeline is arranged between the peripheral temporary water storage area and the reservoir. According to the drainage system, the drainage capacity of the urban drainage system can be improved, the urban waterlogging situation is reduced, and meanwhile damage to urban building facilities is reduced.

Description

technical field [0001] The application relates to the technical field of drainage engineering, in particular to a new type of drainage system for water conservancy engineering channels. Background technique [0002] Drainage system refers to the overall combination of drainage collection, transportation, water quality treatment and discharge and other facilities in a certain way. The general term for all levels of drainage ditches (pipes) and buildings used for waterlogging, waterlogging, and salt prevention. It is mainly composed of field drainage regulating network, drainage ditches at all levels, waterlogging lakes, drainage sluices, pumping stations and drainage capacity and discharge areas. The excess water in the drainage area first flows into the field drainage regulation network, and then is discharged to the drainage area by the drainage sluice or the pumping station through the drainage ditches at all levels or after being stored in the lake. [0003] The urban d...

Problems solved by technology

In recent years, with the increase of summer rainfall in northern my country, the drainage capacity of urban drainage systems in some cities is difficult to meet the demand, and urban waterlogging often occurs, causing accumulated water to stay in the city for a long time, seriously affecting urban operation and pedestrian travel

[0004] In view of the related technologies mentioned above, the inventors found that if the urban drainage system is to be rebuilt more vigorously in order to improve the urban drainage capacity, the engineering volume is relatively large, the renovation cost is high, and it will also cause great damage to the existing urban structure.
