Water stop construction method suitable for collapsible soil
The invention relates to the technical field of water stop construction, in particular to a water stop construction method suitable for collapsible soil. The method comprises the steps that S1, ground treatment is conducted, underground obstacles are explored, removed and reinforced, then the site is leveled, and a construction road, a production pipeline and a temporary power utilization line are arranged; s2, the pile position is measured and placed, and the pile position of later-stage jet grouting pile construction is measured and marked; s3, soil layer double-row high-pressure jet grouting pile construction is carried out, drilling and jet grouting are carried out according to the marks made in the above step, jet grouting piles are constructed in batches in a hole jumping mode, construction is carried out at intervals of every two holes during construction, construction is carried out three times in total, and a double pipe method construction technology is adopted for jet grouting; s4, double-row pressure grouting is conducted on the two sides of the jet grouting pile; and S5, pile body integrity, load test, pile bearing capacity and pressure water injection are inspected through drilling and coring, or permeability coefficients are inspected through a water pumping test. The problem of water seepage of the tailing pond is mainly solved. The water stopping device is mainly used for stopping water in the tailing pond.
本发明涉及止水施工技术领域，更具体而言，涉及一种适于湿陷性土质的止水施工方法。S1：地面处理，对地下障碍物进行探查、清除、加固措施，然后整平场地，布置施工道路、生产用管路和临时用电线路；S2：测放桩位，对后期旋喷桩施工的桩位进行测量、标记；S3：土层双排高压旋喷桩施工，以上述步骤所做的标记进行钻孔、旋喷，旋喷桩采取分批跳孔施作，施工时按每两孔间隔施作，共分三序次，旋喷采用二重管法施工工艺；S4：在旋喷桩的两侧进行双排压力注浆；S5：通过钻孔取芯检验桩身完整性、荷载试验、桩承载力、压力注水，或通关过抽水试验检验渗透系数。本发明主要解决了尾矿库渗水问题。本发明主要用于对尾矿库进行止水。
