TUNNEL FASTENERS FAQS

Tunnel fasteners are specialized fastening systems used in tunnel construction to secure concrete segments, rail systems, and structural components. They are engineered to withstand high tensile loads, shear forces, ground pressure, and environmental stress over long service lifecycles.

Optimas provides bolting systems, dowel systems, centering systems, shear dowels, grout-lift sockets, guiding rods, packers, and precast accessories. These systems are designed to support tunnel segment assembly, alignment, load transfer, and structural stability.

Bolting systems are used to assemble concrete tunnel segments, rail fixings, and conveyor systems. Structural bolt systems can support tensile stresses from 70 to 400 kN and are available in various steel grades and coatings to meet performance and environmental requirements.

Dowel systems fix tunnel rings in place using thermoplastic dowels that enable fast installation while maintaining tight tolerances. They provide stability against ground movement and grout injection pressure during and after tunnel segment installation.

Centering systems and shear dowels help align concrete segments and control shear stress, supporting loads up to 500 kN. They simplify installation and help maintain structural integrity by controlling deflection and segment positioning.

Grout-lift sockets are used to lift and seal tunnel segments during installation. They can provide tightness up to 40 bar and tensile breaking loads up to 600 kN, supporting safe handling and structural sealing during tunnel construction.

Guiding rods and packers control segment positioning, shear resistance, and tolerance alignment between concrete segments. They reduce slip hazards and help ensure accurate installation in tight geometric tolerances.

Tunnel fasteners can be manufactured from stainless steel, structural steel grades such as ASTM A325 and 10.9, and coated with zinc, hot-dip galvanization, or plastic coatings. Material and finish selection depend on load, corrosion exposure, and project requirements.

Tunnel fastener systems can be validated through mechanical testing and finite element analysis to confirm load resistance, deflection behavior, and system performance before implementation. Validation ensures reliability under real-world tunnel conditions.

Engineering support helps ensure fastening systems are correctly specified for ground conditions, structural loads, and installation constraints. Design services and analysis reduce risk, improve safety, and optimize performance throughout the tunnel lifecycle.

Tunnel fastening systems are engineered to support a wide range of structural loads depending on application and system design. Typical solutions support tensile loads from 70 to 400 kN, shear forces up to 500 kN, and breaking tensile stresses up to 600 kN for specific components such as grout-lift sockets.

Tunnel fasteners are validated through mechanical testing and laboratory-based analysis to confirm tensile strength, shear resistance, deflection behavior, and system durability. Testing may be supported by finite element analysis to simulate real-world tunnel loading conditions before deployment.

Tunnel fastening systems are designed to meet applicable structural, material, and quality standards depending on the project and region. Common specifications include structural steel grades such as ASTM A325 and metric grades like 10.9, along with quality systems supported by certified manufacturing and testing processes.

剛開始時，我們對在周向接縫中使用銷釘感到十分懷疑。但是，在Crossrail項目成功之後，塑料銷釘已成為承包商的經典螺栓系統的替代產品。
