tunnel drainage ditch formwork
Wangzu
TDDF
Product Advantages：
| Feature | Plastic Tunnel Drainage Ditch Formwork | Wood Formwork | Steel Formwork |
| Material | High-strength engineering PP or ABS composite | Solid wood, easy to crack/rot, high water absorption | Heavy steel, prone to rust, poor corrosion resistance |
| Construction | Lightweight for manual handling, no heavy machinery required; modular design for fast linear assembly, zero slurry leakage | Needs on-site cutting and nailing, joints leak easily, high damage rate, labor-intensive | Extremely heavy, requires lifting equipment, complex bracing, low construction efficiency |
| Reusability | ≥100 times under normal construction, consistent performance across cycles | 5-8 times, prone to damage and deformation after use | 30-50 times, high risk of deformation and fatigue damage |
| Surface Finish | Smooth, high-precision forming, no secondary plastering required | Rough, uneven surface, mandatory plastering and grinding | Smooth but prone to rust stains, requires surface treatment |
| Water Resistance | Excellent, zero water absorption, no swelling or rotting | Poor, high water absorption, easy to rot and deform | Good but prone to corrosion, requires regular anti-rust treatment |
| Overall Cost Performance | Excellent, lowest total cost of ownership (TCO) | Poor, high long-term material and labor cost | Medium, high upfront and maintenance cost |
| Supporting Services | Complete set of matching accessories + professional technical support | No supporting accessories or technical services | Simple accessories, no professional technical support |
| Modularity | Full accessories, freely splicable, highly adaptable to linear tunnel ditch structures | Fixed size, no standard modular system, poor adaptability | Standard panels, heavy, limited splicing flexibility |
| Eco-Friendly | Eco-friendly, recyclable, zero wood consumption | High, deforestation and material waste | Recyclable but high production energy cost |
| Technical Parameters | Specification | Description |
| Material | High-strength engineering PP or ABS | Impact-resistant rigid plastic specially formulated for underground tunnel moisture and side pressure conditions |
| Application | Tunnel drainage ditch & linear concrete construction | Mainly used for cast-in-place tunnel drainage ditches, culverts and linear underground concrete structures |
| Standard Modular Size | Full modular size series for tunnel use | Includes 30×25×8cm, 45×30×8cm, 150×60×8cm, 150×90×8cm, 150×100×8cm; full customization available |
| Load Bearing Capacity | Excellent load-bearing performance | High structural rigidity, strong side pressure resistance, no bulging or deformation during concrete pouring |
| Surface Type | Smooth anti-adhesion tunnel finish surface | No mortar adhesion, easy demoulding; reduces tunnel inner wall post-finish repair work |
| Temperature Resistance | -20℃ to 60℃ | Wide operating temperature range, suitable for cold, temperate and hot climate construction |
| Splicing Accuracy | High splicing precision | Tight splicing to prevent slurry leakage, ensure straight linearity of tunnel ditches |
| Accessory System | Complete full set of accessories | We provide adjusting blocks, connecting blocks, handles, locking parts and other full system accessories |
| MOQ | 100㎡, trial order negotiable | Flexible MOQ policy to support small-scale trial projects and large-scale bulk orders |
| Lead Time | 7-15 days for customized | Stable production, can match project schedule |
Plastic Tunnel Drainage Ditch Formwork
Plastic Tunnel Drainage Ditch Formwork
Straight Linear Forming Without Secondary Repair
High-precision modular splicing ensures straight tunnel ditch lines, eliminating post-pouring plastering and repair work, saving labor and materials.
Fast Linear Assembly for Long Tunnel Projects
Lightweight panels and complete accessory system accelerate on-site assembly, improving construction efficiency by over 35% for long-distance tunnel drainage projects.
High Reusability Reduces Long-Term Material Cost
Reusable ≥100 times, it greatly lowers material consumption and replacement cost, especially suitable for large-scale tunnel ditch projects.
Anti-Bulging & Deformation-Resistant Under Concrete Pressure
Reinforced internal grid structure resists concrete lateral pressure, ensuring uniform wall thickness and stable forming without bulging.
Smooth Surface Reduces Post-Pouring Workload
Non-stick smooth surface delivers clean concrete finish with minimal bubbles, reducing cleaning and grinding work inside tunnels.
Durable for Underground Humid Environments
Excellent waterproof and corrosion resistance, suitable for long-term buried tunnel drainage systems, extending service life.
