Foundation pit dewatering well plugging method
The invention discloses a foundation pit dewatering well plugging method, and relates to the field of dewatering well plugging, the foundation pit dewatering well plugging method comprises the following steps: vertically drilling a plurality of first mounting holes along the periphery of a well wall on the well wall with a preset distance from a well mouth, filling waterproof glue into the first mounting holes, and inserting positioning steel bars into the first mounting holes; a steel plate with the outer edge attached to the well wall is placed on the positioning steel bars; one end of a water pumping pipe penetrates through the second mounting hole to be placed below the bottom of the foundation pit, and water is pumped through a water pump till the water level of the dewatering well is lowered below the bottom of the foundation pit; the water pumping pipe is drawn out, and the second mounting hole is blocked; concrete is poured into the dewatering well; the steel plate with the outer edge attached to the well wall is horizontally arranged in the dewatering well, the concrete is poured with the steel plate as the bottom face, and the density of the steel plate is larger than that of the concrete, so that the sealing performance of plugging of the dewatering well is enhanced, and the situation that water bursts again in the dewatering well after plugging is avoided.
本发明公开了一种基坑降水井封堵方法，涉及降水井封堵领域，其通过在距离井口预设尺寸的井壁上，沿着井壁四周垂直钻设有多个第一安装孔，在第一安装孔内灌满防水胶，并插入定位钢筋；在定位钢筋上放置外缘与井壁贴合的钢板；将抽水管的一端穿过第二安装孔放至基坑底以下，并通过抽水泵抽水，直至降水井的水位降至基坑底以下；抽出抽水管，并堵塞第二安装孔；向降水井内灌注混凝土；本发明通过在降水井中水平设置外缘与井壁贴合的钢板，以钢板为底面灌注混凝土，由于钢板的密度大于混凝土，因此增强了降水井封堵的密封性，避免了在封堵后降水井内重新涌水。
