Segment bolts, particularly designed for tube and metro construction, are engineered to provide exceptional holding power and adjustability in the assembly of precast concrete segments. These bolts are vital for the secure and stable construction of tunnel segments, ensuring the structural integrity of underground transportation systems and utilities.
Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.
Grade: The product grade is different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.
Advantage:
Rugged Construction: Built with robust materials to endure the challenging conditions encountered in tunneling operations.Galvanized Finish: Hot-dip galvanizing offers a protective coating that guards against corrosion, essential for the longevity of the bolts in the damp tunnel environment.Precision Adjustment: Allows for minute adjustments to achieve perfect alignment during the segment assembly process.Versatile Application: Suitable for a broad range of construction projects, including but not limited to metro stations, water and sewage systems, and underground storage facilities.Reliable Performance: Critical for maintaining the safety and stability of tunnel structures, reducing the risk of structural failure.
Scope of
Application
Tunnel Lining: Secures the individual segments that form the tunnel lining in metro and tube construction projects.Civil Engineering: Utilized in civil engineering projects for the construction of culverts, retaining walls, and other reinforced concrete structures.Mining: Employed in the securement of supports and structures in mining operations.Infrastructure Reinforcement: Used for the reinforcement and retrofitting of existing tunnels and other underground infrastructure.
Quality
Certification
Hebei Bentley is ISO9001:2015 certified and equipped with relevant certificates for quality assurance. Due to its specific dimensions and performance levels, it is suitable for a wide range of industrial and commercial scenarios including, but not limited to: machine building, construction work, transport, energy industry, timber frame connections.
inspection
Bentley has invested a huge amount of money to builda product testing laboratory, equipped with importedhigh-end instruments:such as thread comprehensivescanners, high temperature tensile testing machines,high frequency fatigue testing machines, etc., to ensurethat all products are strictly tested before leaving thewarehouse to ensure the reliability of customers duringuse.
