Wind Turbine Foundation Steel Formwork

Wind turbine foundation steel formwork is prefabricated steel formwork designed for mass concrete foundation pouring of onshore wind turbine towers. Made of high-quality thickened Q235 steel plate through CNC bending and seamless welding, it adopts a modular arc-shaped segment structure. It can be customized in foundation diameter, height and multi-step structure according to wind turbines of different power ratings, accurately controlling foundation roundness, verticality and surface flatness. With outstanding overall rigidity and lateral pressure resistance, it withstands the huge lateral pressure of mass concrete pouring. Featuring bolted quick-assembly structure, convenient disassembly and durable turnover, it adapts to complex field construction environments and is the core prefabricated tooling for wind power foundation construction.

• Full specification customization: Matches foundation drawings of turbines with various power ratings, perfectly adapts to foundation designs of plains, mountains, Gobi and other sites; one set can fit multiple foundation specifications by adjusting segments.
• High rigidity against form expansion: Thickened steel plate with vertical & horizontal reinforcing rib system delivers high structural strength, withstands huge lateral pressure of mass concrete pouring, no deformation or slurry leakage, ensuring accurate foundation dimensions.
• Efficient modular assembly: Segmented design facilitates transportation and on-site hoisting; bolted fast connection achieves much higher formwork efficiency than traditional assembled formwork, greatly shortening wind power foundation construction period and adapting to multi-site relocation.
• High forming accuracy: CNC bending ensures standard radian, tight joints deliver seamless fitting. The roundness, flatness and verticality of the finished foundation meet the high-precision requirements of wind turbine tower installation without secondary grinding.
• Durable turnover & low cost: Sturdy integral steel structure resists field sun, rain and corrosion, reusable across multiple projects. Its life-cycle amortization cost is much lower than traditional assembled formwork with outstanding economic efficiency.

Foundation construction of onshore centralized wind power industrial parks; foundation pouring of distributed wind power projects in mountains and hills; mass foundation construction of wind power bases on plains and Gobi deserts; can be matched with HDPE ground protection mats to form a complete construction solution for wind power projects.
