Background

Along with the development of the urbanization process and the continuous expansion of the scale, the problems of siltation and pollutant accumulation of the drainage pipelines become more and more serious, and a large amount of pollutants exist in the drainage pipelines of a plurality of cities at home and abroad at present, so that the siltation problem of different degrees occurs.

The siltation problem of the drainage pipeline is caused by sediment and suspended solid deposition in a pipeline system, the flow rate of sewage in the drainage pipeline decreases after the sewage enters a drainage pipe with a small gradient from a drainage pipe with a large gradient, and the sediment and the suspended solid carried in the sewage are easily deposited in a pipe with a small gradient, so that the siltation of the drainage pipeline is caused. The flow of sewage is admitted to the pipeline in dry season and the velocity of flow of sewage all is far less than the rainy season value in the pipeline, and this makes silt and the suspension solid that rainy season can be taken away by sewage deposit when dry season, and then arouse that drainage pipe silts up. The siltation among the drainage pipe such as plastic bag, branch, leaf, silt, grit etc. can make the interior sewage velocity of pipeline reduce to hold back grease and floater, thereby reduce the transport capacity of pipeline, aggravate drainage pipe's siltation, when the siltation reaches the certain degree among the drainage pipe, the transport capacity of pipeline can sharply descend, and the speed of siltation can accelerate gradually, finally causes the pipe blockage. Therefore, it is necessary to invent a municipal drainage pipeline for preventing silting to solve the above problems.
