Construction method of mine pit slope water gushing and water stopping flexible curtain wall
The invention discloses a construction method of a pit side water gushing and water stopping flexible curtain wall, which comprises the following steps of: 1, collecting previous hydrogeological data of an open pit coal mine, determining a side water gushing injected stratum, analyzing the pore and crack development conditions of the injected stratum, and determining the groutability of the injected stratum; 2, red clay in the open pit coal mine is analyzed, basic properties are obtained, a data basis is provided for the optimal proportion of a grouting material, and the proportion of different types of grout is finally determined through a groutability test; step 3, designing and constructing a slurry making system which can adapt to rapid switching of different slurries and is adjustable in slurry flow; 4, forming a dynamic grouting control process according to the development characteristics of pores and fractures of the grouted stratum in combination with the specific gravity of different types of grout and the grouting pressure; and 5, grouting parameters are corrected and optimized in real time through the water level observation hole and the water quantity of the side water gushing points, the grouting technology is improved, and the grouting technology which is short in construction period and low in manufacturing cost is provided.
本发明公开了矿坑边帮涌水止水柔性帷幕墙的构建方法，步骤1，收集露天煤矿以往水文地质资料，确定边帮涌水受注地层并分析受注地层孔隙、裂隙发育情况，确定其可注性；步骤2，对露天煤矿内红黏土进行分析并获取基本性质，为注浆材料最优配比提供数据基础，通过可注性试验，最终确定不同类型浆液配比；步骤3，设计并施工能够适配不同浆液快速切换和浆液流量可调的制浆系统；步骤4，根据受注地层孔隙、裂隙发育特征结合不同类型浆液比重及注浆压力，形成动态注浆控制工艺；步骤5，通过水位观测孔和边帮涌水点水量，实时进行注浆参数的修正和优化，用于制浆注浆工艺的完善，提供了一种施工周期短、造价成本低的注浆工艺。
