Metro segment bolts, also known as subway bolts, are specifically designed for securing the cement segments used in the construction of metro tunnels. These bolts are crucial for the stability and safety of the tunnel structure. They are typically made from high-strength materials and are often hot-dip galvanized for corrosion resistance, making them suitable for the demanding environments often found in underground construction.
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:
High Strength: Designed to withstand the heavy loads and pressures exerted in tunnel construction.Corrosion Resistance: Hot-dip galvanized to protect against rust and corrosion, ensuring long-term durability.Adjustability: Allows for fine adjustments during the assembly of tunnel segments for a precise fit.Versatility: Can be used in a variety of tunneling and construction projects, including mining and other underground engineering.Safety: Plays a critical role in ensuring the structural integrity of metro tunnels.
Scope of
Application
Metro and Subway Construction: Used to secure the cement segments that form the tunnel lining.Tunneling Projects: Employed in various tunneling projects where segment assembly is required.Mines and Underground Facilities: Utilized in mining operations and the construction of other underground facilities.Reinforcement of Existing Structures: Ideal for reinforcing or repairing existing tunnel segments.
