[0002] The flap-gate type initial rain storage tank is an urban rainwater management facility that temporarily stores rainwater at the initial stage of rainfall to reduce the impact of rainwater runoff on the urban drainage system. At the same time, it can remove some pollutants in the initial rainwater and protect the water environment. The flushing device of the initial rain storage tank is a maintenance device for cleaning the initial rain storage tank. The flushing device of the initial rain storage tank can ensure the normal operation of the initial rain storage tank and extend its service life.
