高压喷射注浆防渗加固若干问题探讨
|
摘要
高压喷射注浆作为一种将水力采煤与静压注浆相结合诞生的注浆形式,已成功应用于地质灾害治理、水库大坝及垃圾渗滤液防渗加固等工程中,取得了显著的社会经济效益。从高压喷射流的特性、高压喷射注浆机理、高压喷射注浆形成防渗固结体的影响因素及其防渗性能、高压喷射注浆对地层切割搅拌范围的影响因素、高压喷射注浆对浆材的要求,以及高压喷射注浆常见事故及对策6个方面对高压喷射注浆防渗加固进行了较为全面的探讨,提出了将包括SJP注浆材料、仿生非光滑技术等在内的新技术应用到高喷注浆防渗加固中解决目前存在问题的新思路,是一种有意义的尝试,同时也是切实可行的。
High pressure jet grouting as a grouting form born of the hydraulic coal mining and static pressure grouting combination has been successfully applied to geo-hazard prevention,reservoir dam and landfill leachate seepage prevention and reinforcement engineering,and achieved remarkable economic and social benefits. This paper discusses high pressure jet grouting seepage prevention and reinforcement from six aspects,including characteristics of high pressure jet flow,mechanism of high pressure jet grouting,factors influencing the formation of anti seepage consolidation body by high pressure jet grouting and its imperviousness,factors influencing the cutting and mixing range of high pressure jet grouting in formations,requirements of high pressure jet grouting on grouting materials,and common accidents and countermeasures of high pressure jet grouting. It has been put forward that the application of new technologies such as SJP grouting material and bionic non-smooth technology to high pressure jet grouting for resolving existing problems is a meaningful attempt and is also feasible.
