地下工程渗漏水是较为常见的现象。通常地下工程渗漏水可分为三类:点漏、缝漏(含裂缝、施工缝、伸缩缝等)以及大面积慢渗。近年来,点漏、缝漏已有较为成熟的治理技术和防水材料,但对大面积慢渗,人们始终没有满意的治理方法和防水材料。所谓大面积慢渗,是指 Leakage of water in underground works is a common phenomenon. Leakage water in underground works can be divided into three types: point leakage, joint leakage (including cracks, construction joints, expansion joints, etc.) and large area of ​​slow seepage. In recent years, point-leakage and joint-leakage have been relatively mature treatment techniques and waterproof materials, but people have not been satisfied with the treatment methods and waterproof materials for large-area slow-seepage. The so-called large-area slow penetration refers to
