高喷灌浆技术在公平水库除险加固中的应用

Application of high pressure jet grouting technology in Gongping Reservoir Reinforcement project

结合公平水库除险加固工程地质条件,通过试验确定大坝加固高喷灌浆施工参数,详细介绍了高喷灌浆(摆喷)施工方法、施工质量过程控制及质量检验要点,并总结经验。加固后,对坝体渗流监测表明:防渗效果明显。

Combined with the engineering geological conditions of Gongping Reservoir Reinforcement Project, tests were conducted to determine the construction parameters of high pressure jet grouting. A detailed introduction wasmade on the construction method and construction quality control of high pressure jet grouting （oscillating jet） as well as the key points of quality examination. Experience is summarized. The seepage monitoring records after themain dam was reinforced show obvious seepage resisting effects.
