Well sealing method and device for farmland water conservancy irrigation well
The invention relates to the technical field of well shut-in treatment, in particular to a farmland water conservancy irrigation well shut-in method and device, the well wall of a farmland irrigation well is dug out, a temporary sump is dug around the irrigation well, a steel pipe 1-2 cm smaller than the inner diameter of the irrigation well is inserted into the irrigation well, and the height difference of underground water and the water level in the irrigation well is increased; the underground water inrush pressure is reduced, a submersible pump is placed in the irrigation well along a steel pipe, the water level in the irrigation well is pumped out through the submersible pump to be lower than the horizontal height of a foundation pit raft, then a mixture of water glass and cement paste is used for conducting grouting plugging on a well opening where the water level is lowered, and the plugging height is flush with the bottom of the foundation pit raft. And when water glass and cement paste are grouted, efficient mixing can be conducted through the collecting pipe and the mixing pipe, the quality of the mixed cement paste is improved, and the problem of basement water seepage after later building construction is completed is solved.
本发明公开涉及封井处理技术领域，具体为一种农田水利灌溉井封井方法及装置，挖出农田灌溉井井壁，并在灌溉井周围挖一处临时集水坑，采用比灌溉井内径小1‑2cm钢管插入灌溉井内，增加地下水与灌溉井内水位高度差，减少地下水突涌压力，将潜水泵沿钢管放入灌溉井内，通过潜水泵将灌溉井内水位进行抽出，使其低于基坑筏板水平高度，然后通过水玻璃和水泥浆的混合物对降低水位的井口进行注浆封堵，且封堵高度与基坑筏板底部齐平，提高封堵的强度性能，且在水玻璃和水泥浆注浆时，通过汇集管和混合管可进行高效混合，提高混合后水泥浆的质量，避免后期建筑施工结束后的地下室渗水问题。
