The invention relates to the technical field of engineering construction, solves the problem that in the prior art, a precipitation well is not prone to being blocked, and particularly discloses a precipitation well blocking method. Multiple pieces of water absorption resin are put into the precipitation well to form a water absorption layer, and water in the precipitation well is converted into colloid through a coagulant; the characteristics of the colloid are utilized to settle sand grains and broken stones in the water, so that the quicksand phenomenon is reduced; when the colloid is adsorbed on the inner wall of the precipitation well, some sand grains, broken stones and water absorption resin can be adsorbed on the inner wall, so that the quicksand phenomenon is further inhibited, and water seepage can be reduced; and a mixture and a pre-blocking material are added into the precipitation well in sequence and are tamped in sequence, so that the water absorption resin expands to the periphery, soil on the side edge of the precipitation well is extruded and tamped, the density of the precipitation well is improved, the water permeability is reduced, the mixture is prevented from losing efficacy, and a relatively dry environment can be provided for final blocking.
本发明涉及工程施工的技术领域，解决了现有技术中降水井不易封堵的问题，并具体公开一种降水井封堵方法，通过在降水井中投入多个吸水树脂以形成吸水层，并通过混凝剂将降水井中的水转换为胶体，利用胶体的特性沉降水中的沙粒和碎石，减少流砂现象，且胶体吸附在降水井的内壁上的时候，会将一些沙粒、碎石以及吸水树脂吸附在内壁上，进一步抑制了流砂现象，也会减少其渗水，并先后往降水井中添加混合料以及预封堵材料，并依次进行夯实，可以使吸水树脂向周围膨胀，对降水井侧边的土进行挤压夯实，提高其密度，降低透水率，防止混合料失效，并能提供一个较为干燥的环境进行最后的封堵。
