Large-flow karst pipeline type water gushing point grouting plugging method
The invention discloses a large-flow karst pipeline type water gushing point grouting plugging method. The large-flow karst pipeline type water gushing point grouting plugging method comprises the following steps that a drainage pipe is arranged at a water gushing point, and a drainage valve is installed at a water outlet of the drainage pipe; the opening degree of the drainage valve is controlledfor drainage, and primary speed reduction is carried out on high-flow-speed gushing water in a karst pipeline; a grouting drill hole is constructed in the upstream position of the water gushing point, aggregate is injected into the water gushing pipeline, and the water flow speed is reduced again; and grouting is carried out on the water gushing pipeline, and plugging of the water gushing pipeline is achieved.
本发明公开了一种大流量岩溶管道型涌水涌水点注浆封堵方法，包括以下步骤：在涌水点安置引流管，并于引流管出水口安装引流阀；控制引流阀的开度进行引流，对岩溶管道内高流速涌水进行初步降速；在涌水点上游位置施工注浆钻孔，向涌水管道注入骨料，再次降低水流流速；对涌水管道进行注浆，实现涌水管道的封堵。
