Drainage hose cleaning mechanism and water supply and drainage device for deep foundation pit

Abstract

The invention belongs to the technical field of drainage equipment, and particularly discloses a drainage hose cleaning mechanism and a water supply and drainage device for a deep foundation pit. Thedrainage hose cleaning mechanism is convenient to clean residual clay in a drainage hose. The water supply and drainage device for the deep foundation pit comprises the drainage hose cleaning mechanism. The drainage hose cleaning mechanism comprises a water supply pipe, a water drainage hose, a cleaning ring, a support rod, an adjustable limit component and a spring. By adjusting the adjustable limit component to make the adjustable limit component leave a limit position, the spring can be transformed from a compressed state to a natural state, and the support rod is pushed to move along its own axis, so that the cleaning ring is driven by the support rod moving from one end of the water drainage hose toward the other end of the drainage hose to clean the remaining clay in the drainage hose and to dredge a hose wall stuck by the clay.

Description

technical field [0001] The invention belongs to the technical field of drainage equipment, and in particular relates to a drainage hose cleaning mechanism and a water supply and drainage device for deep foundation pits. Background technique [0002] Deep foundation pit refers to a foundation pit with an excavation depth of 5 meters or more, or a basement with three floors or more, or a project whose depth is less than 5 meters, but the geological conditions, surrounding environment and underground pipelines are particularly complicated. . At present, water supply and drainage devices for deep foundation pits generally include submersible pumps and pipes connected to the submersible pumps; when deep foundation pits are drained, the submersible pumps are placed in the deep foundation pits for pumping. In existing water supply and drainage devices, submersible pumps and pipelines are usually rigidly connected, and the diameters of submersible pumps and pipelines are usually no...

AI Technical Summary

Problems solved by technology

In existing water supply and drainage devices, submersible pumps and pipelines are usually rigidly connected, and the diameters of submersible pumps and pipelines are usually not uniform in size. However, there will be clay residue in the drain hose during the drainage process. The clay accumulated in the drain hose for a long time will not only make the hose wall stick together, but also cause the drain hose to block
