Water-rich soft plastic loess tunnel underground water seepage control method based on dewatering well pumping and drainage
The invention relates to a water-rich soft plastic loess tunnel underground water seepage control method based on dewatering well pumping and drainage. The method comprises the steps that dewatering wells are arranged on the ground surface of the two sides of a water-rich soft plastic loess tunnel in rows; the dewatering wells are washed after being constructed; and the water content of a soil layer is reduced through regular water pumping operation of the dewatering wells, and the purpose of controlling groundwater seepage of the water-rich soft plastic loess tunnel is achieved. The method solves the problem that the groundwater seepage seriously affects construction of the water-rich loess tunnel; key parameters of the surface dewatering well arrangement process are determined; and through ground precipitation, the underground water seepage flow in a hole of the water-rich soft plastic loess tunnel is reduced, the loess water content is reduced, normal construction of the loess tunnel is ensured, and the purposes of safe and efficient construction are achieved.
本发明涉及基于降水井抽排的富水软塑黄土隧道地下水渗流控制方法，方法为：于富水软塑黄土隧道两侧地表成列布置降水井；降水井施做完成后进行洗井；通过降水井定期抽水作业，降低土层含水率，达到控制富水软塑黄土隧道地下水渗流的目的。本方法解决了地下水渗流严重影响富水黄土隧道施工的难题，确定了地表降水井布置过程的关键参数，通过地表降水，减少了富水软塑黄土隧道的洞内地下水渗流量，降低了黄土含水率，确保了黄土隧道正常施工，达到了安全高效施工的目的。
