High-pressure Jet-grout Retaining Wall for Foundation Pit

Abstract:

The southern ramp of the Beidaokou overpass is only 2.0m from the resident building at Guangyu Road, Tielin, Liaoning, which makes it impossible to construct the retaining wall with open excavation. Through comparison of various alternatives, the jet-grouting method is adopted. This article describes the jet-grouting process and its benefits.
