The slurry type mud max method is a large diameter slurry type pipe jacking method that can handle high water pressure and boulders. By using the SMC system (jacking monitor & thrust control system) together, the sharp curve and long-distance with a diameter of φ800 mm to φ3000 mm pipe jacking is now possible.
①The maximum gravel size is about 800 mm
②The content of gravel is about 60% (the uniaxial compressive strength of gravel is about 200MN /㎡).(The uniaxial compressive strength of rock is about 100MN /㎡)
