前言化学灌浆是我国在50年代未开始研究,1964年在水电、煤炭、交通等部门相继进行了现场试验,70年代发展较快。我省自1975年以来已先后用铬木素浆液于横溪水库含泥沙砾坝基中建成90米长的灌浆帷幕;用丙凝灌浆处理了新路岙水库坝肩风化岩层的渗流及对河口水库隧洞因电站水锤事故所造成的9条环形漏水裂缝,皎口水库大坝廊道的一般渗水裂缝,雅溪电站混凝土拱坝坝基帷幕;用甲凝灌浆处理了对河口水库电站蜗壳裂缝,皎口水库电站发电洞水平裂缝等;用环氧树脂灌浆处理了多个工程的梁板裂缝;用聚氨酯灌浆处理了皎口水库
Preface Chemical grouting is not started in China in the 1950s, 1964 in the hydropower, coal, transportation and other departments have conducted field trials, rapid development in the 1970s. In our province, chrome lignin slurry has been used to build a 90-meter-long grout curtain in the silty dam foundation of Hengxi Reservoir since 1975. The seepage grouting of the weathered rock strata at the dam shoulder of Xinluo Reservoir has been treated with Propagation grouting, 9 ring-shaped water leakage cracks caused by the water hammer accident in the tunnel, general water seepage cracks in the corridor of Jiaokou Reservoir, and dam foundation curtain of the concrete arch dam of the Yaxi Hydropower Station. A crack on the volute of Hekou Reservoir Hydropower Station was treated with A grouting grouting, Jiaokou reservoir power station horizontal cracks and other holes; epoxy grouting treatment of a number of works of the beam crack; with polyurethane grouting treatment Jiaokou Reservoir
