高压喷射灌浆防渗墙技术在浍河水库除险加固工程中的应用

Application of Seepage-preventing Wall Formed by Jet Grouting in Consolidation Project of Huihe Reservoir

文中对高压喷射灌浆防渗墙技术在浍河水库除险加固工程中的应用进行了总结,指出在多种土层条件下应用时,做好现场试验及地质条件勘察、合理控制提升速度及中途停喷孔的搭接长度是确保墙体质量的关键。

This paper summarizes the technique of seepage-preventing wall formed by jet grouting in consolidation project in Huihe Reservoir. It points out that under the condition of many soil layers, the keys to ensure project quality of seepage-preventing wall are： making good job on test in situ and on geologic exploration survey, reasonable controlling lefting speed, determining lap length of these drill holes, the drilling of which has stopped in halfway.
