Siphoning type rainwater drainage and recovery system

Abstract

The invention provides a siphoning type rainwater drainage and recovery system, which comprises a sediment trap and a rainwater drainage well. A sediment barrier strainer is disposed between the sediment trap and the rainwater drainage well. A well cover for a rainwater collection opening is disposed at the top of the sediment trap. A siphoning rainwater hopper is disposed in the rainwater drainage well. One end of a rainwater hopper drainage pipe is connected to the siphoning rainwater hopper, and the other end of the rainwater hopper drainage pipe is connected with a drainage stand pipe in a potential well through a first horizontal drainage pipe. The potential well is communicated with a rainwater collection well through a second horizontal drainage pipe. Air-water separation is achieved by means of the siphoning rainwater hopper. Rainwater diverted to the drainage stand pipe falls to result in siphoning, so that the rainwater is drained to the rainwater collection well at a high flow speed, and drainage volume and flow speed are increased greatly. Owing to the sediment trap, before the rainwater enters the rainwater drainage well, impurities such as sludge in the rainwater are separated to the sediment trap to facilitate cleaning, and blockage of a drainage system is prevented effectively.

Description

Technical field [0001] The invention relates to a rainwater discharge and recovery system, in particular to a siphon rainwater discharge and recovery system. Background technique [0002] At present, most urban rainwater discharges are slope-oriented gravity flow, that is, gravity flow is used to discharge rainwater. In this discharge method, a large amount of gas and water are mixed, the drainage speed is low, and full pipe circulation cannot be achieved. Therefore, the actual drainage pipe flow and velocity Far below the design requirements. In addition, debris and other debris on the ground can easily block the drainage pipeline, not only causing water on the road surface, but also difficult to dredge the pipeline. Summary of the invention [0003] The technical problem to be solved by the present invention is that in view of the shortcomings of the existing rainwater drainage system, a siphon rainwater drainage and recovery system is provided, which can greatly increase the d...
