1. according to the invention, the sedimentation tank of the rainwater and sewage collecting well is arranged, so that sundries with larger volume are precipitated, and the blockage of a sewage pipe is avoided; meanwhile, the sedimentation tank designed by the invention can be pushed and moved to the inlet of the inspection well through an auxiliary tool under the guiding action of the two sedimentation tank guide rods, then the sedimentation tank is pulled up and taken out for regular cleaning, the operation of the underground limited space is changed into ground work, the inconvenience that the traditional operation and maintenance personnel have limited operation space in the inspection well and the operation and maintenance personnel overhaul the inspection well is avoided, the later-stage operation and maintenance are facilitated, the operation convenience is increased, and the operation cost is reduced; meanwhile, under the condition that toxic and harmful gases of operators in the inspection well are unknown, the operators can clearly draw out sundries and overhaul the objects in the inspection well, and the safety of the operators is greatly improved.
2. According to the rainwater and sewage flow distribution device, the swinging wane facility is arranged according to the rainwater and sewage flow distribution characteristic, rainwater and sewage can be automatically distributed according to the rainwater and sewage flow quantity, and compared with the traditional facilities which need to drive a gate to be opened and closed and a water pump and the like by electric power, the wane does not need to consume energy sources such as electric power and the like, so that rainwater and sewage can be intelligently, environmentally and energy-saving distributed.
3. Aiming at the complex environment conditions of cities and towns, the invention provides the inspection well for distributing the rainwater and the sewage, and the inspection well has wider application range compared with the traditional simple sewage inspection well and the traditional rainwater inspection well. Under the complicated environmental condition in cities and towns, like seafood market and farm trade market etc. most concentrate for the pollution and produce the region, rely on traditional simple setting rain sewage reposition of redundant personnel pipe-line system, can't effectively solve the problem with sewage discharge inlet rain water pipe-line, also can't solve the problem of rainwater sewage reposition of redundant personnel. The inspection well for rainwater and sewage diversion effectively solves the problem of rainwater and sewage diversion and discharge under complex environmental conditions such as seafood markets, farmer markets and the like, and has great significance.
