Large Diameter Shield Initiation and Arrival Technique
Shield initiation and arrival are the two processes most prone to accidents in shield tunneling construction, and they are also a very important link in shield tunneling construction. The shield machine type is different, the structure of the shaft wall starting mouth and arriving mouth is different, and the starting and arriving operations are also different. At present, many accidents of shield tunnel in China occur in the process of shield tunnel construction, and the reason is mostly soil instability. This is because during the start-up and arrival of shaft construction, pile driving and excavation disturb the surrounding strata, resulting in stress release of the section, that is, the soil is unstable. This chapter introduces the technology of shield initiation and arrival, including the construction method of shield initiation and arrival, the soil reinforcement technology at the end of the tunnel and the construction technology of shield initiation and arrival.
