Problems solved by technology

None of these patents involves extending the rainwater runoff route at the initial stage of rainfall, delaying the peak time of storm runoff, and increasing the residence time of rainwater in the building area, keeping the soil layer moist for a long time, which is prone to odor and hygiene such as mosquitoes and flies Therefore, for residential areas with high sanitation conditions and landscape requirements, the pollution control technology for stormwater runoff should be carefully selected

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] see figure 1 with figure 2 A baffle-type open drainage channel for controlling rainwater runoff in the building area is shown, including an open drainage channel body arranged under the green space of the building area or / and next to the road. The surface of the open drainage channel body is rectangular and the ground is inclined. One short side of the main body is provided with a water inlet, and the other short side is provided with a water outlet; the open drainage channel body is provided with an external drainage ditch 2 along a long side, and one end of the external drainage ditch is provided with an inlet facing the open drainage channel body. The overflow baffle 1 of the water outlet, the other end of the external drainage ditch communicates with the outlet of the open drainage ditch body; the open drainage ditch body is provided with t...

Abstract

The invention discloses a water drainage open channel for treating and controlling runoff of rainwater of residential areas in a baffling manner, which comprises a water drainage open channel body arranged under a green space of a residential area or / and beside a road. The top of the water drainage open channel body is rectangular while the bottom of the water drainage open channel body is inclined, a water inlet is arranged at a short edge of the water drainage open channel body, and a water outlet is arranged on another short edge of the water drainage open channel body. The water drainage open channel is characterized in that an external water drainage ditch is arranged in the water drainage open channel body along a long edge; and a plurality of baffling galleries which are perpendicular to the external water drainage ditch and are connected end to end are disposed in the water drainage open channel body. The baffling type water drainage open channel which is coordinated with a water drainage ditch of the residential area is designed besides green buildings, green spaces and roads of the residential area, so that a rainwater runoff path is elongated, emergence time of rainwater flow peak of the residential area is delayed, the time for the rainwater to flow into an urban rainwater pipe network is delayed, flood drainage pressure of the urban rainwater pipe network when in storm days is reduced, and possibility of urban waterlogging is reduced.

Description

technical field [0001] The invention belongs to municipal drainage facilities, in particular to an open drainage channel for diversion treatment and control of rainwater runoff in building quarters. Background technique [0002] my country's annual precipitation is abundant. In recent years, with the continuous development of my country's urbanization, the proportion of permeable surface area has become smaller and smaller, and waterlogging caused by rainfall in various cities has also occurred continuously. Non-point source pollution has become a deteriorating urban water environment. one of the important reasons. [0003] At present, the main technical measures to control non-point source pollution include Best Management Practices (BMPs) in the United States, Sustainable Drainage Systems (SUDS) in the United Kingdom, and Low Impact Development (LID) proposed by New Zealand. In the building area, LID technology can deal with non-point source pollution and control rainstorm...
