Research on the Application of New Suspended Shaft Tunneling Technology in Caisson Construction
Based on the vertical tunneling excavator invented by German company Herrenknecht,this paper introduces a new type of suspended shaft tunneling technology.Shanghai Zhuyuan Bailonggang sewage connection pipe engineering applied this technology.Compared with the traditional caisson construction technology,the new suspended shaft tunneling technology can greatly shorten the construction period and have less impact on the surrounding area,which meet the call for green construction sites in the new era.The vertical tunneling equipment and segment adopt prefabricated assembly technology,which can reduce the demand for the site and shorten the construction period.It has the characteristics of simplicity and integration.Over-excavation control and shaft wall lubrication can reduce the disturbance of the shaft to the surrounding soil,and also ensure the smooth sinking of the shaft.The research content of this paper can provide reference for similar engineering.
