Taming the “Upper-Soft-Lower-Hard” Strata
The 838.74m Nandan Section presents a geological nightmare, featuring a mix of siltstone, mudstone, and mixed-face ground. Sunward’s engineering team optimized the cutterhead design to ensure stability when transitioning between soft soil and full-section hard rock.
Equipped with a 1,350kW power system, Sunward No. 85 is built for reliability in fracture zones with high groundwater pressure.
