Product Description:
Glued Steel Fiber for Tunnel (ZT65/35CH) is a high-strength reinforcement material designed for tunnel
shotcrete, underground excavation support, and structural concrete reinforcement. It consists of hooked-end steel fibers bundled with water-soluble glue, ensuring excellent dispersion in concrete mixing while preventing fiber balling.
After mixing, the glue dissolves completely, allowing individual fibers to distribute uniformly throughout the concrete matrix. This improves crack control, toughness, and energy absorption in tunnel linings and underground structures.
Glued hooked-end steel fiber is a type of steel fiber reinforcement used to replace or reduce traditional rebar mesh in tunnel construction. It provides three-dimensional reinforcement, improving the structural performance of shotcrete in demanding underground environments.
Key structural advantages include:
Improved tensile and flexural strength
Enhanced ductility and impact resistance
Reduced crack propagation
Better energy absorption under ground stress
Faster and safer tunnel construction
Key Features of Glued Steel Fiber for Tunnel
Excellent Anti-Cracking Performance
The fiber network forms a 3D reinforcement system that effectively controls:
Plastic shrinkage cracks
Structural cracks under load
Fatigue and vibration damage
Superior Tunnel Shotcrete Performance
Widely used in underground construction because it provides:
High energy absorption
Strong rock deformation resistance
Improved lining stability
Reduced rebound rate during spraying
Controlled Dispersion (Anti-Balling Technology)
The glued bundle design ensures:
Easy mixing with concrete
Uniform fiber distribution
No fiber clumping
Stable workability during pumping and spraying
Strong Mechanical Anchorage
Hooked ends significantly improve:
Pull-out resistance
Load transfer efficiency
Structural toughness
Advantages in Tunnel Engineering Applications
1. Improved Tunnel Safety
Glued steel fibers enhance the ductility of shotcrete, allowing the lining to absorb ground pressure deformation without sudden failure.
2. Faster Construction Speed
Eliminates or reduces the need for:
Steel mesh installation
Complex rebar binding
Manual reinforcement positioning
This significantly improves tunneling efficiency.
3. Lower Construction Cost
Reduced labor cost
Lower material waste
Faster cycle time
Less equipment dependency
4. Better Shotcrete Quality
Reduced rebound loss
Denser concrete structure
Improved surface integrity
Higher long-term durability
