Grouting and water plugging reinforcement method for water-rich tunnel
The invention discloses a water-rich tunnel grouting and water plugging reinforcement method, and a water-rich tunnel grouting material mainly comprises lignocellulose, polyether polyol, isocyanate, a catalyst, a chain extender, cement and the like. The water plugging and reinforcing application method refers to a method for plugging tunnel gushing water and reinforcing a tunnel lining and a rock stratum by injecting a water-rich tunnel grouting material into a tunnel lining and a surrounding rock through a curtain grouting pipe or a small guide pipe or an advanced anchor rod at high pressure in a single slurry pump or double slurry pumps. According to the method, the grouting material with high strength, low water permeability coefficient and excellent durability can be obtained, the water-rich tunnel can operate safely and stably for a long time, and the service life of the water-rich tunnel is prolonged.
本发明公开了一种富水隧道注浆堵水加固方法，富水隧道注浆材料主要包括木质纤维素、聚醚多元醇、异氰酸酯、催化剂、扩链剂、水泥等组成，堵水加固应用方法是指富水隧道注浆材料在单浆泵或双浆泵通过帷幕注浆管或小导管或超前锚杆经高压注入隧道衬砌和围岩以封堵隧道涌水和加固隧道衬砌与岩层的方法。该方法可得到高强度、低渗水系数、耐久性优良的注浆材料，并能够使富水隧道长期安全稳定的运营，延长富水隧道的使用寿命。
