Design and Construction of High-pressure Rotary Jet Grouting Pile Embedded with Pre-stressed Reinforced Concrete Squared Pile Enclosure System
Abstract:Based on the analysis and comparison of advantages and disadvantages of traditional deep foundation pit enclosure systems, a new enclosure system was created by combining high-pressure jet grouting curtain with pre-stressed reinforced concrete square pile, which was applied in the projects, and the construction cost was greatly reduced with huge economic benefits.
