Stepped bioretention device for runoff on highway pavement
The invention discloses a stepped bioretention device for runoff on a highway pavement. The device comprises a pre-sedimentation tank and bioretention tanks, wherein the pre-sedimentation tanks are arranged at a highway side ditch, and the bioretention tanks are attached to the pre-sedimentation tank; and the biological detention tanks are arranged in a stepped manner from top to bottom, and flow guide main pipes for flow guide are arranged on the side walls of the biological detention tanks. According to the bioretention device in the technical scheme, solid particles in initial rainwater runoff can be removed in the sedimentation tank through the sedimentation effect through the pre-sedimentation tank, rainwater is discharged into the bioretention tanks through the water outlet of the pre-sedimentation tank and permeates and is purified through a bioretention tank filler, rainwater purified by the bioretention tank filler flows into a drainage ditch at the bottom of a roadbed through a main drainage pipe, and when the rainfall intensity is large, the rainwater flows into the lower-stage bioretention tank through the overflow drainage pipe and is stagnated, stored and purified through the lower-stage bioretention tank, so that the aim of stagnating, storing and purifying the runoff of the expressway step by step is achieved.
本发明公开了一种高速公路路面径流的阶梯形生物滞留装置，包括设置于公路边沟处的预沉淀池和与预沉淀池贴合布置的生物滞留池；所述生物滞留池为多个且多个生物滞留池从上到下呈阶梯式布置，所述生物滞留池侧壁上设置有用于导流的导流主管；本技术方案的生物滞留装置，通过预沉淀池，初期雨水径流中的固体颗粒物可在沉淀池中通过沉淀作用被去除，雨水通过预沉淀池出水口排入生物滞留池，并通过生物滞留池填料进行渗透及净化，经生物滞留池填料净化后的雨水通过总排水管流入路基底部排水沟，降雨强度较大时，雨水则通过溢流排水管流入下阶生物滞留池，并通过下阶生物滞留池进行滞蓄和净化，实现对高速公路雨水径流的进行逐级滞蓄及净化的目的。
