Description

Water collecting and draining system matched with groove downcomer well Technical Field The utility model belongs to the technical field of drainage systems, and particularly relates to a water collecting and draining system matched with a groove downcomer well. Background In the construction process of the water diversion pipeline, a pipeline groove needs to be excavated, and in a sandy soil layer area with shallow buried depth of underground water, in order to ensure dry groove operation, the underground water level needs to be reduced, and a pipe well dewatering method is often adopted. A pipe well dewatering and drainage system generally comprises dewatering pipe wells, a water pumping device, drainage pipes and the like, wherein each well dewatering pipe well is provided with a separate drainage pipe for draining groundwater. If the drainage around the groove is inconvenient, when the drainage distance is long, the matched drainage pipeline of each hole pipe well is required to be long, and the problem exists in the operation process that the pipeline is not enabled (namely, the drainage cannot be continued) due to the fact that the pipeline is long and the flow in the pipeline is small in a scene of insufficient water in the downcomer well, the mud and sand components in the drainage are settled in the pipeline, the effective section of the pipeline is reduced, and finally, the pipeline is disabled.
