Before the arrival of the rainy season every year, the rainwater carries a large amount of solid waste such as leaves, garbage, and sediment through the storm water outlet. Not only is it easy to block the drainage pipes, but the long-term accumulated waste will emit a bad smell, which seriously affects the normal life of residents. , often cause complaints from residents, especially in some places; the municipal department needs to clean the rainwater outlet, but it is time-consuming and laborious, and the cleaning cost is increasing year by year; therefore, it is necessary to install a sewage intercepting device at the rainwater outlet to intercept the garbage entering the rainwater outlet , and cleaning it regularly can effectively prevent the clogging of rainwater outlets and drainage pipes, and at the same time reduce the management cost of rainwater outlets; it can be seen that the rainwater interception device with reasonable structure and easy use can greatly facilitate the drainage of rainwater outlets. management, economically feasible.

At present, most domestic rainwater interception devices adopt a single rainwater grate structure. The sewage interception devices of existing urban road rainwater inlets mostly use 500×300mm or 750×500mm standard iron grates, and the size of the water inlet tank is too large. Long-term sedimentation of the inlet and drainage pipes is easy to block the pipes; most of the existing sewage interception devices have problems such as too much weight, inconvenient cleaning, and affecting the flow capacity of the rainwater outlet, which seriously hinders the applicability and popularization of the rainwater interception device .
