Mine tunnel gushing water plugging method and device
The invention relates to the technical field of tunnel fractured rock mass gushing water plugging, in particular to a mine tunnel gushing water plugging method. The method comprises the following steps that S1, cofferdam stacking is carried out, specifically, cofferdams are stacked in the vertical direction by using cofferdam bags at the position 2-3m away from the wall surface of a tunnel face; S2, geotextile is laid, specifically, the geotextile is laid on the inner sides of the cofferdams; and S3, filling is conducted, specifically, grouting filling is conducted on the inner side of the geotextile with an underwater non-dispersible material, after solidification, a water stop retaining wall is obtained, and gushing water plugging can be achieved. The invention discloses a tunnel gushing water plugging device. A water stop retaining wall is formed by adopting a new method of firstly stacking the cofferdams and then performing layered pouring, so that the construction process is simplified, the construction efficiency is improved, the construction quality is improved, and a reliable foundation is provided for grouting and water plugging; and the underwater non-dispersible material is adopted, operation can still be carried out when a working face has certain accumulated water, the construction quality is not affected, good flowability and micro-expansibility are achieved, the contact face can be sealed and compacted after pressure grouting filling, and contact grouting does not need to be carried out subsequently.
本发明涉及隧道破碎岩体突涌水封堵技术领域，特别是一种矿山隧道突涌水封堵方法，包括以下步骤：S1、码围堰：在距离隧道掌子面的壁面2～3m处用围堰袋沿竖直方向码设围堰；S2、铺设土工布：在围堰内侧铺设土工布；S3、填充：用水下不分散材料在土工布内侧进行注浆填充，凝固后，得到止水挡墙，即可实现突涌水封堵；本发明公开了隧道突涌水封堵装置。本发明通过采用先码围堰后分层浇筑的新方法形成止水挡墙，简化施工工序，提升施工效率，提高施工质量，为注浆堵水提供可靠的基础；采用的水下不分散材料，工作面有一定的积水仍可作业，不影响施工质量，具有良好的流动性和微膨胀性，通过压力注浆填充后接触面能够封堵密实，后续无需再进行接触注浆。
