Application and Discussion of High Pressure Jet Grouting Reinforced Cement-soil Pile Anchor Support Technology in Soft-clay Deep Foundation Pit Encolsure

Abstract:

High pressure jet grouting reinforced cement-soil pile anchor is a new advanced geotechnical reinforcement and support technology. In this paper, combined with 2 engineering cases of retaining pile (SMW or composite piles in row) high pressure jet grouting reinforced cement pile anchor bracing system, it is illustrated that the high pressure jet grouting reinforced cement-soil pile anchor support technology has the advantages of good economic performance, convenient construction and good adaptability with good comprehensive benefits, and the problems of construction in deep soft-clay soil are also pointed out.
