Plugging method for dewatering well of high-water-level high-pressure-bearing pit
The invention provides a high-water-level high-pressure-bearing-pit dewatering well plugging method, which relates to the technical field of dewatering well plugging, and comprises the following steps: in the construction process of a foundation bottom plate, welding two annular water stop steel sheets at the periphery of a well mouth of a dewatering well, injecting concrete into a corrugated pipe, and after the concrete is solidified, manufacturing a corrugated pipe prefabricated concrete cylinder; the method comprises the following steps: taking out a water suction pump in a dewatering well, winding a water swelling strip outside the water suction pump, filling corrugated pipe prefabricated concrete cylinders wound with the water swelling strip into the dewatering well in sections, and injecting concrete with the same label as a foundation slab into the dewatering well, according to the method, an existing construction technology is improved, corrugated pipes are used for manufacturing corrugated pipe prefabricated concrete columns for backfilling and plugging, the difficulty of plugging of the dewatering well is greatly reduced, the plugging period is shortened, the cost is saved, and the risk of later leakage is greatly reduced.
本发明提供了一种高水位高承压坑降水井封堵方法，涉及降水井封堵技术领域，包括在基础底板施工过程中，在降水井的井口外围焊接两片环形止水钢片、在波纹管的内部注入混凝土，待混凝土凝固后，制成波纹管预制混凝土圆柱，并在其外部缠绕遇水膨胀止水条、将降水井内部的抽水泵取出后、分段将缠绕有遇水膨胀止水条的波纹管预制混凝土圆柱填入至降水井的内部，采用与基础底板同标号的混凝土在降水井内注入混凝土，形成井内混凝土封填层对降水井内部进行封堵，本发明通过对现有施工工艺进行改进，使用波纹管制作波纹管预制混凝土柱来进行回填封堵，极大的降低了降水井封堵的难度，缩短封堵周期，节约成本，并极大的降低了后期渗漏的风险。
