Discarding catch basin connected with anti-silting precipitation trash removal pipeline

Abstract

The invention belongs to the technical field of municipal drainage pipelines and particularly relates to a discarding catch basin connected with an anti-silting precipitation trash removal pipeline. The discarding catch basin connected with the anti-silting precipitation trash removal pipeline comprises the anti-silting precipitation trash removal pipeline and an discarding catch basin, wherein the anti-silting precipitation trash removal pipeline comprises a rainwater pipeline wall, an impermeable layer, a rainwater pipeline bin, trash cut inclined nets, buffer slopes, precipitable gratings,bottom precipitation ports, high-lift trash removal pumps, silt output pipelines and precipitation desilting grooves; the discarding catch basin comprises a storage and purification tank, a catch basin cover, an activated carbon core filter layer, an oil removal layer, a nonwoven geotextile layer, connecting rods, float balls, a piston slide, slide pistons, discarding water collection control cavity control holes, an discarding water collection control cavity, an discarding down pipe, a drainage pipeline, rainwater pipelines, a water pump and a water pumping pipe. The discarding catch basin purifies, stores and recycles rainwater while the rainwater is drained effectively, so that automatic control of desilting, purification, discarding and storage of the rainwater is realized, and industrialization process and sponge city construction can be promoted.

Description

technical field [0001] The invention belongs to the technical field of municipal drainage pipes, and in particular relates to an anti-silting and sedimentation cleaning pipe connected to an abandoned rainwater well. Background technique [0002] With the development of urbanization and the continuous expansion of scale, the problem of siltation and pollutant accumulation in drainage pipes is becoming more and more serious. At present, there are a large amount of pollutants in the drainage pipes of many cities at home and abroad, and different degrees of siltation problems have appeared. [0003] The silting problem of the drainage pipe is mostly caused by the deposition of sediment and suspended solids in the piping system. The flow velocity of the sewage in the drainage pipe becomes smaller after entering the drainage pipe with a steep slope from the drainage pipe with a large slope, and the mud carried in the sewage Sand and suspended solids can easily settle in pipes with...
