Description

Drainage pipe with plugging structure

Technical Field

The utility model belongs to the technical field of municipal drainage engineering, and particularly relates to a drainage pipeline with a plugging structure.

Background

During pipeline plugging, in order to keep normal drainage system operation, the conventional practice is to set up lift pumps with enough shifts to pump up upstream incoming water to the downstream of a plugging section, the practice has a good effect on sewage pipelines, and for converging pipelines or rainwater pipelines, the fluctuation range of water quantity along with rainfall working conditions is large, and the situations of overflow of sewage or urban waterlogging caused by insufficient shifts often occur.

The current domestic patent library mainly adopts an air bag plugging mode about the plugging mode of the drainage pipeline. The improvement and optimization of the air bag plugging are realized, the applicable pipeline range is limited by the specification of the conventional air bags in the market, and the air bag plugging device is generally applicable to medium-sized and small-sized drainage pipelines, and cannot achieve good plugging effect on the drainage pipelines with larger specifications. The large-specification drainage pipeline is usually connected, supported, plugged and the like under the action of a plurality of hydraulic cylinders. The hydraulic cylinders have reliable plugging capability and supporting capability, have the capability of plugging against the water flow direction (the water facing end), facilitate judging the effectiveness of plugging and supporting, and are beneficial to the safety of downstream maintenance operation. However, the device has a complex structure and high cost, and is not beneficial to large-scale popularization.
