High Pressure Jet-grouting Used for Vertical Control of Seepage Through Dam Foundations

摘要:

1 998年洪水过后 ,堤坝防渗工程量急剧增加 ,与此有关的各种技术方法大量应用。高压旋喷注浆是其中的技术方法之一。简述了目前国内用于堤坝防渗处理的各种技术方法的应用效果和不足 ,重点阐述了高压旋喷注浆技术在堤坝防渗加固中的应用情况、适用范围、防渗机理、技术参数、施工技术及质量检查方法等问题。

Abstract:

Since the flood in 1998, the engineering to control the seepage though dam foundations have increased rapidly, varieties of technical method concerned are widely used. High pressure jet grouting is one of these methods. The article discribed the different behaviours and shortcomings of these methods. The application status, application ranges, mechanism of seepage prevention, technical parameters, using techniques and the inspection methods of quality for the high pressure jet grouting technique are stressed.
