-
摘要: 为解决弓上水库坝基渗漏问题,采用高压喷射灌浆技术处理坝基,进行了钻孔深83m、穿越粘土心墙、控制造孔斜率等一系列研究,革新了造孔工艺,改进了高喷设备及工艺,扩大了高喷应用范围。Abstract: The technique of high pressure jet grouting is adopted to solve the leakage of the dam foundation of Gongshang reservior. Making a series of studies,such as boring 83 meter hole,crossing the central core clay wall,controlling the slope of hole Renovating the boring technique,improving the high pressure jet equipment and technique and enlarging the applied scope of high pressure jet technique.
