Product Introduction
Baked Paint Yellow Customizable Steel Support Series is a specialized temporary structural component designed for construction projects. Its core function is to provide stable lateral and vertical support for deep foundation pits, tunnels and large-scale structural construction, preventing soil collapse and structural deformation to ensure construction safety. Composed of standardized steel pipes, sections or composite components, it is assembled via bolts or welding. It features high load-bearing capacity, strong rigidity, quick assembly and disassembly, and repeatable reuse. As a key safety measure for underground and large-scale construction, it is widely applied in subway projects, high-rise building foundation pits, bridges and utility tunnels.
Product Advantage
Made of Q355B and above high-strength steel, the structure is optimized through finite element analysis. A single φ609 standard support pipe has a design axial compression capacity of over 2500kN. Combined with patented flexible joints and pre-applied axial force technology, it effectively controls foundation pit deformation and protects surrounding buildings.
The product achieves 100% standardized modular design, with highly interchangeable components. Bolted quick-connect fittings boost installation efficiency by over 60% compared to traditional welding. A single support system can be reused 8-12 times on average, significantly reducing project overall costs.
Integrated with an automatic axial force monitoring system with ±1% real-time accuracy, data is transmitted to the IoT platform for remote monitoring. When axial force changes exceed ±10% of the warning value, the system triggers an automatic alarm. Combined with the servo hydraulic system, it realizes dynamic compensation and adjustment of support axial force.
All products undergo CNC plasma precision cutting and beveling, with end flatness error ≤1mm. Production strictly follows standards such as JGJ120 Technical Code for Building Foundation Pit Support. Each batch is accompanied by material inspection reports, and 100% flaw detection is conducted on key welds to ensure product quality.
Standardized design reduces material loss rate to below 3%, with almost no on-site waste. Full-cycle services are provided, from foundation pit design consultation to dismantling and recycling. For special projects, it offers customized supports with diameters ranging from φ300 to φ1200mm and composite sections, adapting to complex geological conditions.

FAQ
Under proper use and maintenance, standard products can be safely reused 8-12 times. After each recovery, components undergo flaw detection, straightening and anti-corrosion treatment, with test reports provided to confirm mechanical properties meet reuse requirements.
The key is to apply precise pre-axial force and conduct real-time monitoring. The system integrates high-precision axial force sensors, connects to the IoT platform for 24-hour dynamic monitoring and over-limit warning, keeping deformation within the design allowable range.
The support system has high flexibility. Through combinations of longitudinal, transverse and corner bracing, plus adjustable-length flexible heads, it can meet the support needs of most irregular foundation pits.
Installation is highly efficient. With standardized components and bolted connection technology, a standard section can be installed within a few hours. Dismantling is even faster, allowing immediate transportation to the next construction site and significantly saving construction time.
