What Are the Transport Securing Methods for Ultra-Thin UHPC Panels (≤20mm)? Safe Transport Securing Solutions and Practical Operation Standards

Ultra-thin UHPC panels (≤20mm) are prone to bending deformation, edge damage and other problems during transportation due to their thin thickness and low stiffness; a scientific transportation fixing method is key to ensuring component integrity. Drawing on its experience in transporting ultra-thin components on projects such as the Huawei Songshan Lake Terminal project, Qinglong analyzes core fixing solutions and practical specifications to ensure safe and efficient transportation.

I. Core Principles of Transportation Fixing for Ultra-thin UHPC Panels

Transportation fixing must follow three major principles: "rigid support, uniform load bearing, and collision protection". Rigid support principle: use flat and sturdy transport racks to ensure panels bear loads evenly and avoid localized compression deformation. Uniform load principle: panels should be placed vertically or inclined (inclination angle ≥75°) to avoid bending caused by horizontal stacking; each panel must have no fewer than 3 support points with support spacing ≤1m. Collision protection principle: flexible cushioning materials should be placed between panels and between panels and the transport rack, with reinforced protection at edges to prevent collision damage. In the transportation of ultra-thin UHPC panels for the Meixi Lake Boston MIZU Salon, Qinglong strictly followed these principles, reducing the component damage rate to below 0.1%.

II. Core Equipment and Materials for Transportation Fixing

Equipment and material selection must match the characteristics of ultra-thin UHPC panels. Transport racks are welded from section steel, with frame dimensions matched to the panels; anti-slip pads and fixing bolts are installed at the bottom to prevent displacement during transportation. Support materials use rubber pads or EVA foam boards with a thickness ≥10mm and moderate elastic modulus, providing both cushioning and preventing panel slippage. Fixing devices use high-strength nylon straps or special clamps, with rubber sleeves wrapped around clamp contact points to avoid surface damage. Collision protection materials use EPE foam or bubble wrap, thickness ≥20mm, to wrap panel edges and corners. In the Nanning Wuxiang China Resources MixC project, Qinglong achieved safe transportation through this equipment combination.

III. Practical Procedures and Key Points of Transportation Fixing

Standardized procedures ensure fixing effectiveness and avoid transportation risks. Before loading, inspect the transport rack and fixing equipment to ensure no damage or deformation; clean panel surfaces thoroughly, apply anti-collision rubber strips to edges, and wrap panels entirely in EPE foam; hoist panels slowly onto the transport rack and place them vertically, adjusting positions so that support points bear loads evenly, with panel spacing ≥50mm and EVA foam boards filled in between; fix panels with nylon straps or clamps at strap spacing ≤500mm with moderate tension to avoid panel deformation caused by over-tightening; cover the top of the transport rack with a rainproof tarpaulin to prevent rain erosion. Through this procedure, Qinglong has achieved zero damage in long-distance transportation of ultra-thin UHPC panels. In addition, transport vehicles should choose smooth road conditions, keep speed within 60km/h, and avoid sudden braking and sharp turns.

IV. Optimized Transportation Fixing Solutions for Special Scenarios

Adjust fixing solutions for different transportation scenarios to improve adaptability. Extra-long ultra-thin panels (length >4m): transport racks adopt segmented supports with an increased number of support points at spacing ≤800mm, and temporary reinforcement bars are added at the middle of panels to avoid bending deformation. Batch transportation: multi-layer transport racks are used, with each layer's height matched to panel thickness and independent supports between layers to ensure uniform load bearing for each layer of panels. Cross-border transportation: containerized transportation is adopted, with rack bottoms fixed inside containers, anti-sway devices added, and panel protection upgraded with double-layer EPE foam wrapping. In the transportation of ultra-thin UHPC panels for the Singapore Defence Service Centre project, Qinglong ensured safe and compliant cross-border transportation through this optimized solution.
