摘要: 针对水电工程隧洞防渗中容易遇到的透水岩体、破碎岩体,介绍了一种综合水溶性聚氨酯、油溶性聚氨酯、环氧灌浆材料的复合化学灌浆方法,通过对它们的科学配比,在提高岩体防渗性能的同时提高了岩体的力学性能、整体性和耐久性,达到了综合永久加固效果。
Abstract: In consideration of thin permeable rock and crumbling rock in hydropower projects, especially in the tunnel seepage prevention project, the paper introduces a grouting technique by use of hydrophilic polyurethane, hydrophobic polyurethane and epoxy composite chemical material. It is used in seepage treatment and permanent reinforcement for the rock. It improves the mechanical properties, intact stability and durability of the rock, worthy reference.
