Tunneling Cutting Picks – Application Cases
Focusing on complex surrounding rock and continuous excavation demands, cutting picks deliver stable cutting and controlled wear in tunneling, ensuring excavation quality and construction efficiency.
Shenzhen Metro Project | ~137 MPa Hard Rock
Shenzhen Metro Project
UCS ≈ 137 MPa, extremely hard rock
Tool life extended by 3×+, tunneling efficiency significantly improved
Guangxi Tunnel Project | F12 “Steel-Plate” Hard Rock Challenge
Guangxi Tunnel Project
UCS ≈ 120 MPa, steel-like hard rock
Tool consumption reduced by over 80%, project progress back on track
Chongqing Water Diversion Tunnel | 100 MPa Challenge
Chongqing Water Diversion Tunnel
UCS ≈ 100 MPa, massive hard rock with no visible joints
Dalian Bay Subsea Tunnel | Hard Rock & Shallow Cover
Dalian Bay Subsea Tunnel
UCS ≈ 100 MPa hard rock + 7 m shallow overburden
Construction period shortened by 35 days, tool wear significantly reduced
