Deep foundation pit support: Steel support controls the deformation of the foundation pit through prestressing technology and resists lateral soil pressure. For example, Tianjin Metro Line Z4-7 adopts a steel support system, which controls the deformation of the foundation pit within 2cm and saves 3 million yuan in costs.
Tunnel construction: used for initial support of tunnels in soft soil or loose formations to prevent collapse. For example, the underground pipe gallery project in Xiong'an New Area adopts a flexible end adjustment design to flexibly respond to sudden loads.
Bridge Engineering
Stability enhancement: In the construction of bridge piers and columns, steel supports are used as temporary load-bearing structures to enhance the bridge's bearing capacity. For example, bridges in Hebei region adopt steel support system to shorten the construction period and optimize the stress.
Large span support: In conjunction with the string beam system, it reduces the amount of temporary support needed and is suitable for the construction of bridges spanning rivers and canyons.
Underground Pipe Gallery and Space Development
Temporary support system: used for large-span structures such as underground garages and comprehensive pipe galleries, providing quick installation and detachable solutions. For example, the underground pipe gallery project in Xiong'an New Area adopts a combination scheme of steel support and buckle scaffolding, which shortens the construction period by 50% and reduces the rental cost by 42% compared to procurement.
Emergency reinforcement: In high water levels or complex geological areas, steel supports and purlins are combined to form a rigid support structure.
other scenarios
Emergency rescue project: Quickly build temporary support structures in loose strata or landslide areas to reduce the impact of disasters.
High rise building foundation pit support: Steel support is used to enhance the stability of the foundation pit enclosure structure and prevent collapse.
