Application of Horizontal Jet Grouting in Qingdao Tunnel Construction

Abstract:

With the background of Qingdao Baoer~Hexi subway station in Water-rich Sand Stratum, research the application of horizontal jet grouting in soils underlain by rock. Introduce the difficulties in engineering and the optimization process in horizontal jet grouting. In order to understand its reinforcement effect, samples to test the point of load and compressive strength, at the same time, analyzes the impact of stratum settlement based on the monitoring data. Monitoring results show that horizontal jet grouting has great effects in control the settlement. The research results would provide guidance for the subsequent construction.
