Abstract

The invention relates to the field of rainwater closure technologies, in particular to a rainwater closure system. The rainwater closure system is characterized in that an electronic-control constant-flow gate with constant water flow is arranged in a sewage disposal pool, a hydraulic automatic gate is arranged between a buffer pool and an initial rain regulating storage pool, a water inlet of the hydraulic automatic gate is higher than the elevation of the bottom of a sewage pipe, a hydraulic-drive downward-opening type weir gate is arranged in a drain channel, and a gate of the hydraulic-drive downward-opening type weir gate can rise along with rise of the level of natural water. The rainwater closure system has the advantages that the hydraulic-drive downward-opening type weir gate is arranged between a closure well and the natural water, the gate can rise by equal amplitude under the control when the level of the natural water rises, and accordingly the natural water can be effectively prevented from flowing backwards.

Description

technical field [0001] The invention relates to the technical field of rainwater interception, in particular to a rainwater interception system. Background technique [0002] After the initial rainwater washes the air and the ground, it will carry a large amount of toxic and harmful substances. According to the investigation, the toxic and harmful substances carried by the initial rainwater are more than domestic sewage. If the initial rainwater is directly discharged to rivers and lakes without treatment, the water body will be seriously polluted, so the initial rainwater needs to be treated. To solve this problem, the interception pipe network system is usually used to intercept the initial rainwater to the sewage pipe and send it to the sewage plant for treatment, while the later rainwater is relatively pure and can be discharged into natural water bodies. When the highest water level of the natural water body is higher than the bottom elevation of the sewage pipe, the w...
