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

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.

Key words:high pressure jet grouting; enclosure test; vertical sealing diaphragm-wall
