高压旋喷灌浆技术在小型水库防渗加固中的应用

The Application of Rotating Jet Grouting Technique to the Seepage Prevention Reinforcement of Small Reservoir

文章结合某小型水库的地层地质及渗漏等情况,对比分析了水库坝体各种防渗加固方案,从经济性和安全性等方面考虑,选用了高压旋喷灌浆防渗墙结合复合土工膜的防渗加固方案.通过试验的成桩效果得出施工参数指导具体工程施工,施工后检测证明高压旋喷灌浆技术效果良好,该方法对水库防渗加固具有借鉴意义.

This paper discusses the high pressure jet grouting impervious wall with composite geomembrane anti-seepage reinforcement scheme. Based on reservoir dam of various impervious reinforcement scheme comparison analysis, and considering the actual situation of a small reservoir geological formation and leakage, it is concluded that construction of parameters to guide the specific project construction, after construction detection that high-pressure jet grouting technology in the small reservoir seepage reinforcement effect is good and the method of reservoir seepage reinforcement would have some practical implications.
