Abstract:

The article analyses the function requirement for the thrust system of the shield machine that should be satisfied in the design and makes a detailed calculation of the designed thrust force of the shield machine. On basis of the structures and dimensions of the shield machine, the article determines the specifications, parameters, dimensions and number of the thrust cylinders. The article also analyses the layout of the thrust cylinders and the compatibility between the thrust cylinders and the segments. After the study, the design method for the thrust system of the shield machine is mastered, which can provide reference for the development and type selection of shield machines in the future.

Key words:  , shield machine  , thrust system  , design  , layout  , control
