Abstract

The invention provides an inflow port structure for a biological retention facility, which comprises a top cover, an overflow grille and a barrel of which the top is open. The overflow grille is arranged along the circumferential direction of the top end of the barrel; the top end of the barrel is in parallel and level to the side edge of a road; an inflow port is formed at one side of the overflow grille, which is close to the road; a filtering device is arranged inwards at the position of an opening of the barrel; the side wall of the barrel is connected with a water outlet pipe; and a wateroutlet of the water outlet pipe is lower than the plane where the top end of the barrel is positioned. According to the inflow port structure for the biological retention facility, which is providedby the invention, by arranging the filtering device and the overflow grille, in a case of light rain, after sundries in rainfall runoff are filtered by the filtering device, when the sundries are accumulated to a certain amount, the sundries directly flow into the biological retention facility through the water outlet of the water outlet pipe; and in a case of heavy rain, the sundries directly overflow into the biological retention facility through the overflow grille, so as to implement low-flow water outlet pipe inflow and high-flow overflow dispersed inflow modes, reduce scouring on plantsnear an inflow port and ensure excellent operation of the biological retention facility.

Description

technical field [0001] The invention relates to the technical field of rainwater collection and purification in a sponge city, and more particularly relates to an inflow structure of a biological retention facility. Background technique [0002] Urban runoff pollution seriously threatens the safety of urban water environment. Due to the large amount of exhaust gas, hydrocarbons and particulate matter produced by the burning of fossil energy by motor vehicles on the road, the oil substances that are not fully burned and leaked during the operation of vehicles, as well as tire wear and brakes are formed. Tire particulate matter and heavy metal substances, etc., cause road rainwater runoff pollution to be particularly serious. In order to deal with road rainwater runoff pollution, under the concept of sponge city construction, bioretention facilities provide an effective way to solve road rainwater runoff pollution. However, due to the serious pollution of road runoff, it dire...
