Product Introduction
Middle Eastern-style Steel Support is a professional temporary structural component for construction projects, dedicated to providing stable lateral and vertical support for deep foundation pits, tunnels and large-scale structural construction. It effectively prevents soil collapse and structural deformation, ensuring construction safety. Composed of standardized steel pipes, profiles or composite components connected by bolts or welding, it features high load-bearing capacity, strong rigidity, quick assembly and disassembly, and repeated usability. It is a core support product for subways, high-rise building foundation pits, bridges and utility tunnels, guaranteeing the safety of underground and large-scale construction projects.
Product Advantage
The product uses Q355B high-strength steel and optimizes structure via finite element analysis. A single φ609 standard support pipe has a design axial compression capacity of over 2500kN. Patented flexible joints and pre-applied axial force technology effectively control foundation pit deformation, protecting surrounding buildings from damage.
The whole system adopts 100% standardized and modular design, with highly interchangeable components. Bolted quick-connection joints increase installation efficiency by over 60% compared to traditional welding. Each support system can be reused multiple times, significantly reducing the overall project cost.
It integrates an automatic axial force monitoring system with a real-time accuracy of ±1%. Data is transmitted to the IoT platform for remote monitoring, and automatic alarms are triggered when axial force changes exceed ±10%. The matching servo hydraulic system realizes dynamic compensation and adjustment of support axial force for real-time safety control.
All products are processed by CNC plasma precision cutting and beveling, with end flatness error ≤1mm. Production strictly follows the Technical Code for Foundation Pit Support of Buildings (JGJ120). Each batch is equipped with 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. The product provides full-cycle services 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 profiles, adapting to complex geological conditions.

FAQ
Under proper use and maintenance, standard products can be safely reused 8-12 times. After each recycling, components undergo flaw detection, straightening and anti-corrosion treatment, and test reports are provided to ensure their 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 data to the network for 24-hour dynamic monitoring and over-limit early warning, keeping deformation within the design allowable range.
The system has high flexibility. Through combination methods such as longitudinal and transverse bracing, corner bracing and eccentric arrangement, and matching adjustable-length flexible joints, it can meet the support needs of most irregular foundation pits.
Installation and dismantling are highly efficient. With standardized components and bolted connection technology, a standard section can be installed within a few hours. Dismantling is faster, and components can be directly transported to the next construction site, significantly saving construction time.
