Types of steel supports

Steel pipe support
Using circular or rectangular steel pipes as the main body, it is commonly used for foundation pit support and has the characteristics of flexible installation and strong bearing capacity.
Common specifications include diameter 400, diameter 580, diameter 600, diameter 609, diameter 630, diameter 800, etc., with a wall thickness typically of 16mm.
For example, in subway construction, Φ 609 or Φ 800 steel pipes are commonly used for support, and a servo system is used to monitor the axial force in real time to ensure the safety of the foundation pit.
Steel support
Using standard steel sections such as H-beams and I-beams as support materials, it is suitable for scenarios with high requirements for strength and stiffness.
For example, in the construction of bridge piers and columns, steel supports are used as temporary load-bearing structures to enhance the bridge's bearing capacity and shorten the construction period.
steel grating
Welded into a grid shape from longitudinal and transverse steel components, commonly used for initial tunnel support.
For example, in tunnels with soft soil or loose strata, steel grids are combined with purlins to prevent collapse.
Combination support
Combine the pull rod with the compression rod to improve stability and load-bearing capacity.
For example, in the construction of large-span bridges, the combination of supports and beam string systems can reduce the amount of temporary supports used.
