An automatic intercepting gully device for early rain

Abstract

The invention relates to a gully device for automatic interception of early rain, which comprises a well chamber and a well top cover, and a first partition and a second partition are arranged at intervals in the well chamber, and the first partition and the second partition are A plate divides the well from one side to the other into a main well, a secondary well and a discharge well. The automatic intercepting gully device of the present invention does not need additional electric start-stop and control equipment, and realizes the effective automatic interception of the initial rainwater, and sends it to the sewage treatment plant for treatment through the urban sewage pipeline system. In this way, the adverse impact of initial rain on the environment of the downstream rainwater receiving water body is reduced, and at the same time, the possibility of sedimentation of muck and suspended matter in the urban rainwater pipeline system is reduced, and the maintenance workload of the urban rainwater pipeline system is reduced.

Description

technical field [0001] The invention relates to the technical field of municipal drainage facilities, in particular to an automatic intercepting gully device for early rain. Background technique [0002] The traditional urban rainwater pipeline system collects rainwater from the road through the rainwater outlet and then flows it into the main rainwater pipe or main pipe, and finally discharges it into the downstream receiving water body. Therefore, the rainwater outlet is the beginning and the most important part of the entire urban rainwater pipeline system. For facilities that collect rainwater from road surfaces, the quality of the collected road surface rainwater will directly affect the operation of the entire urban rainwater pipeline system. The initial rainwater of each rainfall (abbreviation: initial rain) will carry a large amount of dust in the air and dissolve various polluting gases in the air during the process of falling to the ground in the air, and the rainw...

Problems solved by technology

The initial rainwater of each rainfall (abbreviation: initial rain) will carry a large amount of dust in the air and dissolve various polluting gases in the air during the process of falling to the ground in the air, and the rainwater will flow into the rainwater outlet after falling to the ground During the process, the suspended solids and slag on the ground will be taken away. Therefore, the primary rainwater generally contains a large amount of pollutants and suspended solids. Since the traditional gullies do not have any primary rain interception function, that is, for the initial rain The incoming water in the whole process of rainfall is collected and transported to the urban rainwater pipeline system without interception. However, actual engineering cases show that the initial rain will not only pollute the downstream of the urban rainwater pipeline system because of its high content of pollutants and suspended solids. At the same time, it will also lead to the silting and blockage of the urban rainwater pipeline system. In order to reduce the adverse impact on the water environment of the receiving water body and reduce the maintenance workload of the urban rainwater pipeline system, it is necessary to start from the beginning of the urban rainwater pipeline system - rainwater Interception of primary rain
