Well-casing-free dewatering well water pumping device and method
The invention discloses a well-casing-free dewatering well water pumping device and method, and relates to the technical field of dewatering wells, the well-casing-free dewatering well water pumping device comprises a fixing mechanism, a filling mechanism and a drainage mechanism, the drainage mechanism comprises a drainage pipe, a plurality of water inlet holes are formed in the outer side of the bottom end of the drainage pipe, and a filter screen is arranged at the bottom of the inner side of the drainage pipe; a one-way plate is arranged at one end in the drainage pipe, and an air inlet pipe is installed on the outer wall of one end of the drainage pipe. Under the action of internal and external pressure difference of the drainage pipe, underground water in a well hole can enter the drainage pipe and drive the one-way plate to be opened, compressed air is introduced into the air inlet pipe to drive the one-way plate to be closed, and water above the one-way plate can be pushed to be discharged from the interior of the drainage pipe along with introduction of the compressed air; a passive water inlet mode with different pressure differences in the drainage pipe and the well hole and an active compressed air drainage mode are adopted, so that the investment of a dewatering well casing is reduced, the diameter of the dewatering well can be reduced, and the backfilling amount of a filter material is reduced.
本发明公开了一种免井管的降水井抽水装置及方法，涉及降水井技术领域，包括固定机构，还包括填充机构和排水机构，所述排水机构包括排水管，所述排水管底端外侧开设有多个进水孔，所述排水管内侧底部设有过滤网，所述排水管内部一端设有单向板，所述排水管一端外壁安装有进气管。本发明通过排水管内外压差的作用下，使得井孔中的地下水可以进入到排水管内部并带动单向板打开，进气管通入压缩空气可以带动单向板关闭，随着压缩空气的通入，可以推动单向板上方的水从排水管内部排出，排水管和井孔内的不同压力差的被动进水方式和主动压缩空气的排水方式，减少了降水井井管的投入，可以缩小降水井的直径并减少滤料的回填量。
