in the actual tunneling process, the working process of the mobile pressurized tunnel rapid tunneling equipment designed by the invention can be divided into two stages according to the working procedures: a walking stage and a cutting rock breaking stage.
At all stages, the shield body 1, the pressure maintaining mechanism 8 and the surrounding rock 10 are filled with flexible filling medium 803 to provide active temporary supporting force for the surrounding rock 10. In the cutting and rock breaking stage, the shield body 1 is stationary relative to the surrounding rock 10.
