Rectangular Water Channel Steel Formwork

Scope of Application

1. Water Conservancy & Farmland Projects: High-standard farmland irrigation ditches, field drainage ditches, rural water system renovation, small diversion main channels, drainage troughs matched with reservoirs.
2. Municipal Urban Construction Projects: Urban road rain gutters, community garden drainage passages, underground pipe network rectangular culverts, sidewalk catch gutters, urban flood control channels.
3. Highway & Railway Projects: Rectangular side ditches along expressways and national highways, tunnel drainage troughs, station yard drainage channels, slope chutes, diversion ditches for railway roadbeds.
4. Industrial Park Projects: Rainwater drainage ditches in industrial parks, sewage diversion troughs in factories, flood control rectangular channels in logistics parks, diversion galleries of sewage treatment plants.
5. Precast Component Factories: Mass production of prefabricated rectangular box culverts and standard sections of drainage ditches.
6. Rural Infrastructure Projects: Ditches for rural sewage renovation, supporting drainage passages for rural environment improvement.

Structure & Technical Advantages

1. Standard Structural Composition

1. Forming Panel: Made of thickened hot-rolled steel plate with polished inner wall for easy demolding without concrete adhesion; inner rounded corners can be customized on demand.
2. Dense Reinforcement Ribs: Vertically flat steel and transverse channel steel on the back are fully welded in cross layout for reinforcement. Double-layer stiffeners are applied on side walls and bottom under high stress to resist lateral pressure and deformation.
3. Modular Assembly Structure: Split side plate + bottom plate design, with connecting lugs, self-locking buckles and standard tie bolt holes on sides for tight splicing gaps. Integrated box culvert formwork is equipped with opening-closing hinge shafts to avoid prying and hammering during demolding.
4. Standard Pre-reserved Holes: Vibration holes, lifting lugs, water stop strip clamping grooves and positioning holes for embedded parts are pre-drilled in factories, eliminating secondary cutting and processing on site.
5. Anti-corrosion Protection Process: The whole mold is sandblasted for rust removal and coated with multi-layer epoxy anti-rust paint, resisting rust under humid and water-soaked conditions. Hot-dip galvanizing is available as an upgrade for coastal projects.

Core Technical Advantages

1. High Precision & Regular Cross-section: Processed by numerical control cutting without staggered joints during integral forming. The dimensional error of finished products is ≤±1mm, with four vertical sides and uniform wall thickness of channels, achieving fair-faced concrete without plastering and repair.
2. High Rigidity to Prevent Mold Expansion & Displacement: Multi-layer rib reinforcement system bears large lateral pressure of mass concrete, avoiding mold bulging and deformation during pouring, suitable for construction of large-section rectangular box culverts.
3. Slurry Leakage Prevention Sealing Design: Splicing surfaces fit closely and are locked by fastening bolts to eliminate slurry leakage on side walls and bottoms of ditches, avoiding construction defects like honeycombs and pockmarks.
4. High Space Utilization of Rectangular Cross-section: The square section provides regular water passing space without sediment dead corners at the bottom, ensuring stable water flow and convenient dredging & maintenance, with higher bearing capacity than U-shaped channels.
5. Lightweight Disassembly & Transportation: Split modular design with moderate weight per piece, transportable by manpower or small cranes, suitable for construction in narrow foundation pits and narrow field roads.
6. Flexible Customizable Specifications: Standard sizes ranging from 400×400mm to 2000×2000mm are in stock, with a unified 2m module length of channels. Width, height, wall thickness and rounded corners can be customized according to drawings for non-standard products.

Comprehensive Application Functions

1. One-step Integral Casting Function: Cast-in-place construction forms channel bottom plate and double side walls in one go; precast molds directly produce complete rectangular box culvert components, eliminating secondary shaping and plastering procedures.
2. Standardized Shape Control Function: Uniformly restrict the clear width, clear height and wall thickness of channels. Consistent section specifications for mass construction deliver unified overall project appearance and high acceptance pass rate.
3. Free Splicing & Extension Function: Standard 2m single sections are longitudinally connected by bolts for unlimited extension of long-distance channels, adapting to straight channel sections and short gentle curved diversion ditches.
4. Embedded Waterproof Integration Function: The formwork is equipped with fixed clamping grooves for water stop strips and positioning positions for sleeves, preventing displacement of embedded parts and waterproof accessories during pouring and reducing hidden risks of ditch leakage.
5. Reusable Circulation Function: The steel structure is wear-resistant and impact-resistant. One set of formwork can be circulated for more than 50 times and reused across sections and projects.
6. Zero On-site Processing Function: All procedures including bending, welding, hole drilling and anti-corrosion treatment are completed in factories. Only assembly and fastening are required on site without hot cutting and grinding, ensuring safe and tidy construction.
7. Mass Precasting Adaptation Function: Special integrated molds for precast factories can be matched with attached vibrators to mass-produce standardized rectangular drainage components, greatly improving precast production capacity.

Product Overview & Comprehensive Advantages

Product Overview

Comprehensive Product Advantages

1. Quality Advantage: Thickened high-strength steel with double-layer dense reinforcement delivers straight forming corners and precise dimensions, drastically reducing concrete repair and rectification work for one-time project acceptance.
2. Construction Efficiency Advantage: Modular quick buckle assembly speeds up formwork erection and removal by 40%, cutting on-site labor input and shortening the total construction period of drainage channels.
3. Cost-saving Economic Advantage: Far more circulation times than wooden molds and thin iron sheet simple molds. Reuse across multiple projects dilutes procurement costs, with no follow-up plastering, repair material and labor expenses.
4. Durability & Impact Resistance Advantage: Multi-layer anti-rust and anti-corrosion coatings resist outdoor wind and sand, water immersion, low temperature and humid environments, with low risk of rust, deformation and damage during long-term use.
5. Customization Adaptation Advantage: All sizes and special-shaped channels are customizable, applicable to small-size farm ditches and large-section urban box culverts for all drainage working conditions.
6. Green & Safety Advantage: Steel can be 100% recycled without wood waste pollution. No cutting, welding or hot work on construction sites reduces safety risks such as collapse and fire, complying with green infrastructure construction standards.
