Foundation pit maintenance-free drainage dewatering well and construction method thereof

SONG XINPENG / ZHOU YINGYING

The invention relates to the technical field of foundation pit dewatering, and discloses a foundation pit maintenance-free drainage dewatering well which comprises a well body arranged underground. The water pumping pneumatic water pump is arranged in the well body and is used for discharging water in the well body; the rotating mechanism is erected above the well body, connected with the water pumping pneumatic water pump through a transmission belt and used for adjusting the height of the water pumping pneumatic water pump in the well body; the driving mechanism is in transmission connection with the rotating mechanism and used for driving the rotating mechanism; according to the maintenance-free drainage dewatering well for the foundation pit, by arranging the rotating mechanism and the driving mechanism, the conveying belt can be driven by the rotating mechanism and the driving mechanism to control ascending and descending of the water pumping pneumatic water pump, and workers can replace and maintain the pneumatic water pump conveniently; limiting is carried out through the limiting blocks in the fixing base and the limiting grooves in the surface of the well casing to prevent movement, the fixing base and soil can be fixed in a reinforced mode through the fixing protruding blocks, and the well body can be installed more stably.

本发明涉及基坑降水技术领域，公开了一种基坑免维护疏干降水井，包括井体，开设于地面以下；抽水气动水泵，设置于井体内，用于将井体内的水排出；转动机构，架设于井体上方，通过传动带与抽水气动水泵连接，用于调节抽水气动水泵在井体中的高度；驱动机构，与转动机构传动连接，用于驱动转动机构；该基坑免维护疏干降水井通过设置转动机构和驱动机构，可以通过转动机构和驱动机构带动传送带进行控制抽水气动水泵的上升与下降，方便工作人员对气动水泵进行更换与维修操作；通过固定底座内部的限位块与井管表面的限位槽进行限位防止移动，通过固定凸块可以将固定底座与泥土进行加强固定，实现了井体更加稳固的安装。
