Detailed Description

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Example (b): as shown in fig. 1, the mechanical sewage intercepting device capable of preventing rainwater from flowing backwards comprises an intercepting well 1, wherein one side of the intercepting well 1 is connected with a rainwater and sewage inlet pipe 2, the opposite side of the intercepting well 1 is connected with a rainwater and sewage outlet pipe 3, and an intercepting weir 4 is arranged between the inlet pipe 2 and the rainwater outlet pipe 3; the intercepting well 1 is respectively connected with a second water inlet pipe 5 and a sewage intercepting pipe 6 at the other two sides corresponding to the space between the water inlet pipe 2 and the intercepting weir 4, and the sewage intercepting pipe 6 is provided with an automatic control type gate 7.

The intercepting well 1 is a concrete or reinforced concrete well body, the top of the intercepting well is provided with an inspection well mouth 8, and the circle in figure 1 indicates the position corresponding to the inspection well mouth 8.
