Foundation pit drainage device and method

Abstract

The invention discloses a foundation pit drainage device which comprises an L-shaped plate and a plurality of through holes formed in the L-shaped plate, one end of the L-shaped plate is slidably connected with a sliding plate and a drainage component, the drainage component comprises a water pump, a drainage pipe and a filter screen cylinder, the water pump is fixedly connected to the L-shaped plate, and the filter screen cylinder is fixedly connected to the drainage pipe. The water pump is fixedly communicated with the water pump, the drain pipe is fixedly communicated with the water pump, the filter screen cylinder is fixedly communicated with the bottom end of the drain pipe, the clamping part comprises a fixing plate, a sliding block, a rectangular block and a clamping block, a cam downwards extrudes a limiting block when rotating along with a rotating shaft, and a cleaning ring is driven to downwards move along with downward movement of the limiting block and a vertical plate; the cleaning brush is arranged on the inner side wall of the cleaning ring, so that residues and mud on the outer surface of the filter screen cylinder can be scraped when the cleaning ring moves downwards, and the effect of cleaning the outer surface of the filter screen cylinder during drainage is achieved.

Description

technical field [0001] The invention relates to the technical field of drainage equipment, in particular to a foundation pit drainage device and a method thereof. Background technique [0002] The types of foundation pit drainage include open ditch drainage, well point precipitation, and blind ditch drainage. The open ditch drainage is to collect the groundwater flowing into the trench or foundation pit into the collection well, and then pump it away. [0003] With the rapid development of infrastructure, many foundation pits need to be excavated in the early stage of construction, and concrete reinforcement is used to fill the foundation. When the foundation pit is excavated, it is often accompanied by groundwater seepage, and it is necessary to drain the foundation pit, but the existing drainage Because the equipment does not have an automatic cleaning structure for the pipeline filter, when draining, various waste residues in the foundation pit are likely to cause the pip...
