Well point dewatering device and system, and construction method of well point dewatering device

Abstract

The invention discloses a novel well point dewatering device and system, and a construction method of the well point dewatering device. The well point dewatering device includes an anti-slide pile body, a load bearing plate is arranged on the lower side of the anti-slide pile body, a prefabricated pipe and a sand gravel layer are arranged on the lower side of the loadbearing plate, the sand gravellayer is arranged on the outer side of the prefabricated pipe, a submersible pump is arranged in the prefabricated pipe, and the submersible pump pumps the groundwater of the prefabricated pipe to the outside of the well point precipitation device through a submersible pump water pipe. The prefabricated pipe is arranged at the bottom of the anti-slide pile body for storing water, the occupied space of the well point dewatering device is greatly reduced, the well point dewatering device is also allowed to be arranged close to a target, water storage is abound, the effect is good, accumulated water at the bottom of the anti-slide pile body can be timely discharged through the submersible pump, the effect of supporting the anti-slide pile body is achieved in combination with the load bearingplate, the condition of softness of land parcel blocks of the pile bottom of the anti-slide pile body can be prevented, long-term stability of the anti-slide pile body is ensured, and the condition of the collapse of the slope is eliminated.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a well point dewatering device, system and construction method thereof. Background technique [0002] Nowadays, well point dewatering points are often used to lower the underground water level. Generally, flower pipes are buried after drilling holes on the surface, sand and gravel are backfilled around them, and submersible pumps are placed at the bottom of the holes to pump water to reduce the groundwater level around the wells. This method often requires a large number of installations. In order to reduce the groundwater level, the precipitation wells and long-term drainage can be reduced. [0003] As for the manual excavation piles in the landslide control project, due to the abundant groundwater, a large number of precipitation wells need to be installed in the upstream of the pile row to effectively reduce the groundwater near the anti-slide piles and p...

AI Technical Summary

Problems solved by technology

[0004] Due to the influence of anti-slide pile construction, the well point precipitation point needs to keep a certain safe distance from the anti-slide pile to prevent the slope from being damaged. Therefore, the well point precipitation point arranged upstream of the anti-slide pile has not obvious effect on the anti-slide pile position precipitation.
