Sponge city road grading drainage system in collapsible loess stratum
The invention discloses a sponge city road grading drainage system in a collapsible loess stratum. The sponge city road grading drainage system comprises a curb regulation and storage tank, the curb regulation and storage tank is arranged at the junction of a road surface and a green belt, a side opening, close to the green belt, of the curb regulation and storage tank is connected with a first-stage drainage pipe, and two cutoff walls are arranged on the lower portion of the curb regulation and storage tank. A vegetation planting layer, a gravel layer, a lime soil cushion layer and an impermeable film are sequentially arranged between the two cutoff walls from top to bottom, a seepage box is located in the lime soil cushion layer, two openings are formed in the side face, close to the road direction, of the seepage box from bottom to top and connected with a second-stage drainage pipe and a third-stage drainage pipe respectively, and the second-stage drainage pipe and the third-stage drainage pipe both penetrate through the cutoff walls to the side edge of a road. The second-stage drainage pipe is connected into a catch basin or a municipal pipe network, the third-stage drainage pipe is connected into a water guide sand well located on the outer side of a cutoff wall and buried below the road through a square bend, and a permeable pipe is arranged close to the lower portion of the middle of the gravel layer in the longitudinal direction of the road. According to the sponge city road grading drainage system in the collapsible loess stratum, road surface accumulated water can be effectively drained, the application range is wide, and road damage can be avoided.
本发明公开了一种湿陷性黄土地层中海绵城市道路分级排水系统，包括路缘调蓄箱,路缘调蓄箱设于路面与绿化带交界处，路缘调蓄箱靠近绿化带的侧面开口与一级排水管相连，隔水墙设于路缘调蓄箱下部，两隔水墙中间由上至下依次设有植被种植层、碎石层、灰土垫层和防渗膜，渗流箱位于灰土垫层内，渗流箱靠近道路方向的侧面自下而上设有两开口分别与二级排水管、三级排水管相连，且二级排水管、三级排水管皆穿过隔水墙至道路侧边缘，二级排水管接入雨水井或市政管网，三级排水管通过直角弯头接入位于隔水墙外侧、埋设于道路下方的导水砂井，透水管沿道路纵向设于靠近碎石层中间下部。能够有效排除路面积水，适用范围广，可避免道路发生破坏。
