双液袖阀管注浆法在岩溶地区的应用

Application of Slurry Injection by Dual-slurry Sleeve-valve Pipe in Treatment of Underground Karst Cavity

某厂设备基础地基多发育溶洞,用双液袖阀管注浆法配合高压悬喷注浆法进行处理,取得了较好的经济效益.介绍了该法的施工方法和应注意的问题.

The underground earth structure for machine foundation in a certain factory was found with plenty of karst cavities. Accompanying by high-pressure suspension slurry injection, slurry injection by dual-slurry sleeve-valve pipe is applied to treatment the underground of karst cavities. In this paper, the author introduces the construction method of slurry injection by dual-slurry sleeve-valve pipe and summarizes the particular attention that should be paid to in the course of construction.
