Fast-moving deep foundation pit pumping device

Abstract

The invention discloses a fast movable deep foundation pit pumping device. The device comprises a shell, a water absorbing cover, a filter cylinder, a support rod and a power mechanism, wherein the water absorbing cover is of a truncated cone structure; the top of the filter cylinder is located above the shell, the bottom of the filter cylinder is inserted into the interior of the shell and is insealed rotary connection with the top edge of the water absorbing cover, and the circumferential outer wall of the filter cylinder is in sealed rotary connection with the top surface of the shell; thetop of the filter cylinder is rotationally connected with the bottom of the support rod; the power mechanism is used for driving the filter cylinder to rotate. Water inside a deep foundation pit is filtered repeatedly, so that blockage of a pumping pipe in the pumping process is prevented, damage to a pump is avoided, normal water pumping is guaranteed, pumping efficiency is improved, and the service life of the pump is prolonged.

Description

technical field [0001] The invention relates to the technical field of deep foundation pit drainage equipment. More specifically, the present invention relates to a fast-moving deep foundation pit pumping device. Background technique [0002] The initial stage of building construction usually requires the excavation of deep foundation pits. Groundwater, surface water and rainwater will accumulate in deep foundation pits. The water inside deep foundation pits needs to be removed in time and quickly to avoid structural damage caused by long-term blisters in deep foundation pits. In order to prevent the occurrence of construction accidents such as collapses, it is also necessary to provide an environment without water and deep foundation pits for the later construction to ensure the normal progress of the later construction. In the prior art, most of the water inside the deep foundation pit is pumped out by a pump. Since the water inside the deep foundation pit contains a larg...

AI Technical Summary

Problems solved by technology

In the prior art, most of the water inside the deep foundation pit is pumped out by a pump. Since the water inside the deep foundation pit contains a large amount of gravel, stones or other sundries, in the conventional technology, a suction pipe is directly inserted into the deep foundation pit for pumping. There are gravel, stones or other sundries blocking the suction pipe, and the gravel and stones are easy to be sucked into the pump, causing irreversible damage to the pump, causing the pump to not work normally, and affecting the normal pumping work
