Hidden-buried sewage interception facility inside river bank

Abstract

The invention discloses a hidden-buried sewage interception facility inside a river bank, which comprises a confluence pipe disposed inside a bank. A river closure well which is communicated with the confluence pipe is further arranged inside the bank, the river closure well is provided with a sewage interception pipe and an overflow pipe, the sewage interception pipe extends to the lower side of a river, the overflow pipe extends to the river, a grid is arranged between the river closure well and the sewage interception pipe, and a flap valve is disposed on the overflow pipe. by the aid of the hidden-buried sewage interception facility, the problem that the first rain pollutes the river is prevented, the problem of recharge of a large quantity of rainwater when in rainstorm is also prevented, and the hidden-buried sewage interception facility has the advantages of simple structure, convenience in construction, flexibility in arrangement, convenience in running and management and the like.

Description

technical field [0001] The invention relates to the technical field of urban drainage, in particular to a buried sewage interception facility in a river embankment. Background technique [0002] With the development of industrial economy and the discharge of waste water in people's daily life, the rivers in many cities have been seriously polluted, and this phenomenon has become common. Some cities adopt the method of capping the river, but it only solves the problem of the landscape, and does not solve the problem of water pollution. Some river courses have the functions of urban flood control and urban landscape, and the method of covering cannot be adopted. [0003] In order to prevent river pollution, it is necessary to collect initial rainwater and sewage. At present, the common technical means is to intercept the sewage before discharging to the river, so as to reduce the pollution of the initial rainwater and sewage to the river. However, because the rivers of some...

Problems solved by technology

However, because the rivers in some cities are located in the old urban areas, it is difficult to lay pipelines along the coast, and it is difficult to modify and intercept the flow by normal methods. Overflows are prone to occur in rainy days, causing serious pollution to the rivers.
