The double shield rock TBM produced by our company has strong adaptability to adverse geological sections: it is mainly reflected in its strong adaptability to weak surrounding rock, and the excavation speed between Class II to Class V surrounding rock can basically remain stable above 30 m/d. Under the environment of large burial depth, high ground stress, and strong convergence rock strata, its unique targeted design can effectively prevent construction accidents such as jamming.
This model has strong adaptability to adverse geological sections and features safe, efficient, and rapid construction.
