AI Technical Summary
Existing storm drain structures are prone to reduced drainage capacity due to siltation during the initial rainfall, and may even cause pipe blockage. Furthermore, the early rainwater is heavily polluted, making it difficult to effectively intercept and treat pollutants.
Design a rainwater inlet structure with sedimentation function, including a filtration zone, a sedimentation zone, and a clear water zone. The filtration zone intercepts large impurities, the sedimentation zone settles small impurities and allows them to infiltrate into the soil through pipes, and the clear water zone discharges into the rainwater pipe network when overflowing, ensuring the drainage capacity of the rainwater inlet.
It effectively intercepts and treats impurities and silt in the initial rainfall, maintains the drainage capacity of the rainwater inlet, prevents pipe blockage, alleviates rainwater pollution, and improves the drainage efficiency of the rainwater inlet.

The rainwater inlet is generally composed of bottom plate, wall body and rainwater grate. The rainwater grate is the inlet of rainwater inlet, and bears the task of blocking pollutants and discharging rainwater in time.
[0003] Because of the rainfall initial stage, rainwater dissolves a large amount of acidic gas, automobile exhaust, factory waste gas and other polluting gases in the air, falls to the ground, and due to the scouring of roof, asphalt concrete road and the like, a large amount of pollutants are contained in the early stage rainwater, and the pollution degree of the early stage rainwater is higher, even exceeds the pollution degree of ordinary urban sewage, and the rainwater scours the sundries and silt on the road surface to the rainwater inlet, the street side plastic bags, toilet paper, leaflets and other large area garbage are scoured to the rainwater inlet, and are blocked by the conventional rainwater grate, and the small magazines and silt fall into the rainwater inlet through the gap of the grate, and the silt is accumulated for a long time, causing the decrease of drainage capacity, and even pipe blockage.
