高压喷射灌浆构筑垂直防渗板墙围井试验的几个问题

Several Problems with the Test of the Jet Grouted Vertical Sealing Diaphragm-wall Enclosure

摘要:

在简要介绍高压喷射灌浆技术原理的基础上，重点介绍了采用高压摆喷灌浆构筑垂直防渗板墙的围井试验情况，详细分析了围井开挖、注水试验及高喷墙体样品的检验结果，并提出了高压喷射灌浆技术在酸性水、动水、超深孔、含有大块石地层等条件下的应用问题。

Abstract:

After briefly introduction of the principles of the high pressure jet grouting, the emphasis was put on the test of the jet grouted vertical sealing diaphragm-wall enclosure. The excavation of the enclosure, water injection test and wall sample test are detailed. At length, the application of the jet grouting technique in special conditions, such as acid water, flowing-water, deep bore hole, soil layer containing large stones and so on is presented.
