水溶性聚氨酯浆液,是一种新型的化学注浆材料,可用于土木工程中的防水堵漏、大坝基础灌浆和坝体混凝土裂隙的防渗和补强、隧道掘进和矿井建设中涌水地带的止水和破碎带的固结、松软地基加固等。1976年初,煤炭科学研究院建井研究所和江苏省化工研究所协作研制这种浆液,现已取得了成功。这种水溶性聚氨酯浆液(简称WPU, Water-soluble polyurethane slurry is a new type of chemical grouting material that can be used for waterproof plugging in civil engineering, foundation grouting for dams, impervious and reinforcing impervious concrete fissures in dams, tunneling and mine construction. Sealing and consolidation of the fracture zone, soft ground reinforcement, etc. In early 1976, the Institute of Well Research of the Coal Research Institute and the Jiangsu Provincial Institute of Chemical Industry collaborated on the development of this slurry and it has now achieved success. This water-soluble polyurethane slurry (abbreviated as WPU,
