围井试验法在病险水库高压喷射灌浆工程中的应用及其关键点初探

Application and the Key Points of Enclosure Well Test to High-Pressure Jet Grouting Project in Dangerous Reservoirs

在简要介绍高压喷射灌浆技术原理的基础上,着重分析围井试验法对垂直防渗板墙防渗性能检测的优势,并结合工程检测实际,对围井法在病险水库高压喷射灌浆工程中的应用进行了初步的探讨,提出了围井法检测的关键点。

After briefly introduction of the principles of the high pressure jet grouting,the paper analyses the advantage of the enclosure well test on anti-seepage check of vertical sheet-pile wall,and in combination with the engineering practice,carries on the preliminary discussion on enclosure well test in high pressure jet grouting project of the dangerous reservoir application,then puts forward the key points of enclosure well test.
