Plugging material for dewatering well and plugging construction method
The invention provides a dewatering well plugging material and a plugging construction method thereof. The dewatering well plugging material is prepared by mixing the following three components in percentage by weight: 25%-30% of sodium bentonite, 5%-8% of water-absorbent resin and 62%-70% of clay. By the adoption of the technical scheme, the plugging effect between the permeable layer and the water-resisting layer can be improved.
本发明提供了一种降水井封堵材料及其封堵施工方法，所述降水井封堵材料由如下重量比例的三种组分混合制成：25%‑30%的钠基膨润土、5%‑8%的吸水性树脂、62%‑70%的粘土。采用本发明的技术方案，可以提高对透水层和隔水层间的封堵效果。
