Description

TECHNICAL FIELD

[0001] The utility model relates to city drainage technical field, concretely relates to the guide and drain integrated groove of sponge city compatible type disciform drainage structure. BACKGROUND

[0002] The city road drainage system refers to the measures taken to remove the precipitation on the city road surface. Its main function is to quickly remove the rainwater on the road surface to prevent water accumulation from affecting driving safety.

[0003] The surface runoff area is large in the plain area, and the drainage slope is small. In order to meet the flow requirement, the surface soil in the area with gentle terrain is often loose and washed away. When the surface soil flows into the drainage system, it is easy to accumulate in the ditch due to the slow flow rate of the ditch water, reducing the drainage capacity of the drainage ditch.

[0004] In view of the above technical problems, a drainage structure with integrated guide and interception is disclosed in the patent with publication number CN212200677U. The top of the guide dike is above the ground, which can collect slope flood and guide it to the low-lying place. The water interception device can prevent the erosion of the guide dike foundation. The top of the water interception device is lower than the top of the guide dike, so that the flood can enter the drainage structure to achieve the purpose of drainage. The terminal of the drainage structure is connected with the culvert or natural trench to ensure the smooth drainage of the drainage structure. The original ground is used as the bottom of the drainage ditch, greatly increasing the drainage capacity.

[0005] The above-mentioned patent and prior art also have the following disadvantages: the existing city road drainage system mostly uses single-function drainage ditches. The traditional drainage ditch can only realize single drainage function and cannot simultaneously meet the needs of sponge city construction and municipal drainage. The elevation difference between the bottom plane of the drainage ditch and the road surface is large. After the rainwater enters the conventional drainage ditch, the elevation drops too much, which cannot be connected with the downstream sponge facilities such as rainwater garden. The rainwater can only enter the underground rainwater pipe well and other drainage systems with large buried depth. The traditional shallow drainage trench has limited drainage capacity and cannot realize long-distance sponge facility drainage function. In addition, when it rains heavily or heavily, it is easy to cause water accumulation and waterlogging. The traditional drainage system cannot fully utilize rainwater resources, cannot effectively reduce the discharge of surface runoff and pollutants, has insufficient drainage capacity, and the sediment in the rainwater is easy to accumulate in the ditch, which needs frequent maintenance and cleaning.
