TUNNEL TYPE RAINWATER PROCESSING SYSTEM

摘要

A tunnel type rainwater processing system is provided to allow heavy rain to flow into water tanks and then in the soil, and to reduce damage due to the heavy rain by forming rainwater permeable holes in the water tanks and flowing the water from the upper part to the inside of the water tanks. A tunnel type rainwater processing system comprises an inlet pipe(10), a precipitated tank(20), at least one water tank(30), a connecting pipe(40), and a drain pipe(50). The water tanks store the flowed water temporarily. The water tanks flow the rainwater to the underground soil. The water tanks have a plurality of rainwater permeable holes(30a) to flow the rainwater from the upper part to the inner part of the water tanks. The water tanks include front, rear, and center water tanks(31,33,32). Blocking devices(37) are installed between the water tanks to limit the flowed volume of the rainwater.
