Product Description
This arc-shaped tunnel steel formwork is specifically tailored for tunnel lining construction, a key process that determines the structural stability and waterproof performance of tunnels. Most tunnels, whether for highways, railways, or subways, feature circular or horseshoe-shaped cross-sections, and this arc-shaped formwork is designed to perfectly fit these curved lining structures. It addresses the core on-site demand for formwork that aligns with tunnel contours, ensuring seamless concrete pouring for lining works.
The core advantage of this formwork lies in its precision arc-shaped design. Each panel is pre-fabricated in the factory with accurate curvature, ensuring a tight fit with the tunnel’s inner wall when assembled. This eliminates gaps between the formwork and the tunnel surface, effectively preventing slurry leakage during concrete pouring—a common issue that can lead to rework and compromise lining quality. Made of high-quality thick steel, the arc-shaped panels maintain excellent rigidity, capable of withstanding the lateral pressure of wet concrete without deforming, which guarantees the uniformity and smoothness of the finished lining.
Designed for practical on-site application, the formwork adopts a modular arc structure that allows flexible assembly according to different tunnel diameters. Workers can splice the arc panels quickly in the narrow tunnel space, with secure fasteners at connection points to enhance overall stability. The arc-shaped panels are lightweight yet durable, making them easy to transport and handle in the confined underground worksite. Additionally, the smooth surface of the steel panels minimizes concrete adhesion, which simplifies post-curing disassembly and reduces labor intensity.
After construction, the arc-shaped formwork can be disassembled into individual modules, cleaned easily, and stored for reuse in subsequent tunnel lining projects. This reusability helps reduce material waste and long-term construction costs. It performs reliably in various geological conditions, from soft soil tunnels that require careful lining support to hard rock tunnels with high pressure demands. The precision arc design also ensures that the lining meets the required geometric standards, which is crucial for the smooth operation of tunnel ventilation and transportation systems.
For construction teams engaged in tunnel lining projects, this arc-shaped tunnel steel formwork is a practical and reliable solution. Its precision arc design fits the unique requirements of tunnel lining, ensures construction quality, and streamlines on-site operations. Without overstated marketing claims, it delivers the performance and adaptability needed to meet the rigorous demands of tunnel lining construction, helping keep projects on track and up to industry standards.
