Prefabricated U-Shaped Water Channel Steel Formwork

Scope of Application

• Water Conservancy & Farmland Projects: Farmland irrigation ditches, field diversion channels, water-saving reconstruction canals, small river diversion works, trench dredging and renovation projects
• Municipal Engineering: Urban rainwater drainage ditches, residential area drainage channels, supporting trenches for municipal pipe networks, landscape drainage passages
• Highway & Railway Engineering: Highway side ditches, subgrade drainage troughs, drainage ditches along railways, diversion trenches at tunnel entrances and exits, station yard drainage systems
• Rural Infrastructure Projects: Rural sewage drainage ditches, field flood drainage channels, supporting drainage works for rural environment improvement
• Mass Production for Prefabricated Component Plants: Mass fabrication of standard precast U-shaped water troughs, drainage ditches and assembled channel components

Structural & Technical Advantages

1. Standard Product Structure

2. Core Technical Superiorities

• Optimized flow cross-section: The standard U-shaped structure boasts a large hydraulic radius and fast water flow to reduce sediment accumulation. It outperforms rectangular and trapezoidal channels in drainage and water diversion, making it the preferred cross-section for water conservancy projects.
• Integral forming with zero linear deviation: Factory integral bending creates smooth curves and vertical surfaces. Cast concrete features consistent linearity free of offset joints, slurry leakage, honeycombing and pitting, eliminating post-pouring repair work.
• High rigidity against formwork bulging: Dense back rib reinforcement provides strong resistance to lateral concrete pressure, preventing bulging and deformation during pouring, with finished dimensional errors controlled within high-precision industrial standards.
• Excellent sealing for assembly: Flat joint surfaces and accurately positioned bolt holes create minimal assembly gaps, thoroughly solving trench water seepage and slurry run-off issues.
• Long service life with anti-corrosion and wear resistance: Full sandblasting rust removal plus multi-layer anti-rust paint adapts to harsh working conditions including outdoor exposure, high humidity and long-term water immersion with superior wear and corrosion resistance.

Comprehensive Application Functions

• One-step integral forming: On-site casting completes the base slab and two side walls of the U-shaped trough in a single pour, removing secondary plastering and reshaping procedures to directly achieve fair-faced concrete finishes.
• Standardized shaping: Uniform control over clear channel width, clear height, radian and wall thickness ensures consistent specifications for mass construction, unified overall project appearance and high acceptance pass rates.
• Quick splicing for unlimited extension: Designed with unified standard modules, multiple formwork units can be seamlessly connected longitudinally to extend long-distance channels, suitable for straight and gently curved channel sections.
• Embedded part compatibility: Pre-reserved positions for sleeves and waterstops can be customized to match supporting channel water stop, diversion and drainage construction.
• High turnover reusability: Robust steel structure resists bumps and damages, supporting over 50 cycles of repeated use across different construction sections and projects.
• Zero on-site processing: Fully fabricated in factories with no cutting, welding or polishing required on site; only assembly and reinforcement work needed for safe, clean and efficient construction.

Product Profile

Comprehensive Product Advantages

1. Superior quality: Integrally formed with standard linearity and precise dimensions. Completed concrete channels ensure smooth water flow with less ponding and sediment, achieving far better visual and construction quality than traditional formwork.
2. Higher construction efficiency: Modular assembly speeds up formwork erection and stripping, drastically shortening construction periods and cutting on-site labor input, ideal for large-scale mass channel projects.
3. Lower overall costs: High turnover cycles and minimal wear eliminate frequent mold replacement expenses and heavy post-pouring repair costs to reduce total construction expenditure.
4. Durability & stability: Robust structure with strong impact and compression resistance, anti-corrosion and weather-proof properties, free of deformation and rust during long-term outdoor construction for extended service life.
5. Flexible customization: Fully customizable dimensions adapt to various engineering specifications including small farm ditches, municipal main channels and highway side ditches with outstanding universal compatibility.
6. Eco-friendly & safe: Zero timber waste with 100% recyclable steel materials; no hot work on site improves construction safety and complies with green infrastructure standards.
