At the site of the Huaihe River main channel widening project, three continuous rigid frame bridges are being built simultaneously at a rate of 1.2 meters per day. The project engineer holds a laser rangefinder and carefully checks the newly installed cap beam formwork: “This combined formwork system will help us overcome the problem of precision control in deep-water bridge construction.”
As a key project for the navigation upgrade of the Huaihe River Basin, the bridge needs to complete the construction of 42 spans of cast-in-place structures before the flood season, involving eight types of steel formwork systems such as cap beams and pile-tied beams. Faced with complex hydrological conditions and strict construction period requirements, the complete set of solutions provided by Pansol steel formwork is showing its technical advantages.
Technical analysis of five core products.

1. Intelligent cap beam formwork system
   ·Materials and design: Q235b high-strength steel plate (national standard steel) combined with three-dimensional adjustable bearings to achieve 0-5% longitudinal slope adaptive adjustment (project measured data).
   · Demolding efficiency: Patented hydraulic synchronous demoulding device (patented technology), single demoulding time is shortened to 45 minutes, and the number of template turnovers reaches more than 50 times (project acceptance report).
   · Advantages: Solve the problem of construction accuracy in deep water areas and improve the reuse rate of templates.
2. High-performance flat mold system
   · Structural optimization: 6-meter standard modulus flat mold, through the encrypted stiffening rib design (spacing ≤300mm), surface flatness ≤2mm/3m (third-party inspection report).
   · Assembly efficiency: The quick-release lock system increases the template assembly efficiency by 60% (project comparison test data).
   · Application scenario: Replace traditional wooden molds to solve the quality problem of easy deformation of flange plate construction.
3. High-precision cylindrical template
   · Process and tolerance: Cold bending forming process, the radial tolerance of the 1.2-2.4m diameter series template is ±1.2mm (process standard document).
   · Joint technology: staggered joint splicing technology, the concrete joint stagger amount is ≤0.5mm, meeting the standard of clear concrete (project actual measurement record).
   ·Durability: 97% flatness is maintained after 40 turnovers (long-term tracking test data).
4. Load-bearing hoop system
   ·Bearing capacity: The double-reinforced annular hoop has been optimized by finite element analysis, and the ultimate bearing capacity reaches 2800kN (certified by a third-party testing agency).
   ·Adaptability: The modular design supports the adjustment of the pipe diameter from Φ800 to Φ2000mm, and the installation time is reduced by 70% (construction log statistics).
   ·Safety: The safety factor is more than 2.8 times (comparison with industry standards).
5. Pile-beam combination formwork
   ·Flexible adjustment: supports 0-15° inclination adjustment, and is suitable for the construction of special-shaped pile-beams (design plan description).
   ·Demolding effect: polymer demoulding coating technology, concrete surface porosity ≤0.5‰ (laboratory test results).
   ·Anti-interference ability: successfully coped with the complex working conditions of daily water level changes of 1.5m in deep water areas (project construction summary).
   In the wave of new construction mode changes, this construction solution with professional formwork system as the core is redefining the quality standard of large bridge projects. When the last span of formwork is precisely in place in the morning light, what we see is not only a giant steel dragon crossing the natural chasm, but also a mark of the times that China’s infrastructure is moving towards precision construction.
