Sponge type urban rainwater pipeline drainage dredging system

Abstract

The invention relates to the technical field of urban drainage, in particular to a sponge type urban rainwater pipeline drainage dredging system. The sponge type urban rainwater pipeline drainage dredging system is characterized by comprising a plurality of pipelines spliced in sequence and bases used for supporting the pipelines, wherein every two adjacent pipelines are detachably connected; fixing pieces used for fixing the pipelines to the base are arranged between the pipelines and the bases; dredging devices used for dredging pipeline sludge are arranged on the pipelines, each dredging device comprises a lifting sleeve movably penetrating through the inner wall and the outer wall of the top of the corresponding pipeline in the vertical direction and a dredging assembly connected to the lifting sleeve, and the dredging assemblies are located in the pipelines; and driving assemblies used for driving the lifting sleeves to ascend and descend are arranged between the bases and the pipelines. The sponge type urban rainwater pipeline drainage dredging system can reduce the situation that the pipelines are blocked due to the fact that a large amount of sludge deposits in the rainwater pipelines, and improves the drainage effect of the rainwater pipelines.

Description

technical field [0001] The application relates to the technical field of urban drainage, in particular to a sponge-type urban rainwater pipeline drainage and dredging system. Background technique [0002] Sponge city construction is the concept of a new generation of urban stormwater management. It refers to the city's good "elasticity" in adapting to environmental changes and dealing with natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed. [0003] In order to increase the drainage speed, rainwater pipes will be laid in sponge cities. The rainwater pipes in the prior art mainly use PE pipes. PE pipes are plastic sleeves extruded from polyethylene materials, which are corrosion-resistant, wear-resistant and aging-resistant. and other ...

AI Technical Summary

Problems solved by technology

[0004] With regard to the related technologies mentioned above, the inventor believes that there are the following defects: during the long-term use of the pipeline, the silt in the rainwater pipeline accumulates at the bottom of the pipeline as the water flow decreases, and the silt is dehydrated due to the repeated alternation of dry and wet environments in the pipeline. After hardening, it is too late to soften the hardened silt before being washed away by the water flow, and the new silt stays in the pipe again, resulting in poor drainage effect of the rainwater pipe
