Given the complex geological characteristics, the earth pressure balance TBM with a diameter of 10.03 meters tailored by China Railway Engineering Equipment Group for the project is equipped with a series double-screw machine system, which not only enhances the adaptability to high water pressure and large-size pebble strata but also ensures the construction safety and improves the tunneling efficiency. The machine has achieved a maximum excavation mileage of 28 meters per day and 504 meters per month.
