State of Jet Grouting in Shanghai
With the fast development of subways, tunnels, and high-rise buildings in Shanghai in the past 10 years, jet grouting technology has been widely used in various projects which also further promote its development. In addition to the single, double and triple pipe methods, an engineering method similar to RJPI has been used. The treatment depth has increased to approximately 50m from 20–30m. The main objectives of using jet grouting technology in the above projects are: foundation reinforcement and formation of water insulation curtain. Since soil layers in Shanghai are soft, adopting jet grouting technology to form vertical or horizontal water-resisting bodies of different depths and thicknesses has become an important means to achieve this purpose. In combination with the actual examples of application, this paper presents the status of jet grouting applications in Shanghai area in the past 10 years and looks into the prospects for technological developments in the future.
