Lianggong Tunnel Formwork has set a new industry benchmark, enabling one-time simultaneous casting of walls and slabs to form seamless cellular reinforced concrete structures. Designed for repetitive standardized projects, this all-steel modular system redefines efficiency, delivering superior concrete finishes and accelerating construction timelines for contractors worldwide.
What Are Advantages of Tunnel Formwork?
● One-Piece Casting, Unmatched Efficiency: Eliminates the tedious “walls first, slabs later” cycle with simultaneous pouring of walls and slabs. Achieves a full floor cast in just 3 days (full configuration), slashing project duration by 40% vs. traditional formwork.
● All-Steel Durability & Reusability: Crafted from high-quality Q235 steel (3.5mm thick panels, robust frame structures), our tunnel formwork system withstands over 200 reuse cycles. Resistant to wear, impact and deformation, it delivers long-term cost savings by minimizing replacement needs.
● Modular Design for Easy Operation: Factory-preassembled components enable quick on-site assembly and disassembly. Equipped with movable casters, tunnel formwork construction reduces on-site handling frequency, boosting turnover efficiency.
● Enhanced Safety & Stability: Integral working platforms, edge protection and modular support systems distribute pouring pressure evenly, preventing tunnel formwork collapse or displacement. Minimal tool requirements reduce on-site accident risks.
● Flexible Adaptability: Customizable dimensions fit diverse layout requirements (space span: 2.4–2.6m, floor height ≤3m). Compatible with automated pouring equipment for standardized assembly-line operations, ideal for large-scale developments.
What Are Core Tunnel Formwork Components?
Every component is precision-designed to work seamlessly, ensuring reliability, safety and efficiency. Our tunnel formwork diagram is as follows:
1. Formwork System
The backbone of tunnel formwork system, responsible for shaping walls, slabs and ends with high precision.
● Main Components: Wall formwork, top formwork and end formwork.
● Material & Design: The pannel is 3.5mm thickness Q235 steel plate. The main beam is 6.3# double channel. The secondary beam is a 63×63 character beam and the frame is 63 channel steel for robust support.
● Key Features: Top formwork uses lifting beams instead of main beams for enhanced lifting stability. End formwork is customized for project-specific nodes.
● Connection: Bolt and C-type connectors ensure tight, aligned joints between panels.
2. Support System
Ensures structural rigidity during pouring and adjusts for levelness, adapting to on-site conditions.
● Main Components: Push-pull prop, caster support, single-side support and wall form support.
● Design Advantages: Caster support features a lightweight, modular design with good compatibility and adjustability—no project-specific redesign needed.
3. Guide Wall System
Guarantees accurate positioning of tunnel formwork, ensuring consistent wall/slab alignment across floors.
● Main Components: Single-side/double-side guide wall, straight formwork, angle formwork and clamps.
● Key Features: Supports both single-side and double-side casting. Clamps secure the guide wall to the foundation, preventing displacement during pouring.
4. Blocking System
Seals gaps and forms irregular sections for seamless concrete casting.
● Main Components: Wall blocking plates, floor blocking plates and fastening screws.
● Material & Design: 3.5mm thick Q235 steel panel with 8mm thick Q235 frame and 2.5# angle steel support frame. Φ10 hole on the frame enable direct screwing to the panel.
● Key Feature: When inverted, the blocking system is hoisted integrally with the template.
5. Lifting System
Facilitates efficient hoisting of tunnel formwork, both for single sets and multiple groups.
● Main Components: Lifting hook, hook, lifting beam.
● Design Details: High-capacity lifting hooks handle integral hoisting of multiple formwork groups during inversion. Low-capacity hooks turn single sets upright during assembly. Lifting beams press on the top formwork, strengthening it while bearing lifting loads.
● Safety: High load-bearing capacity ensures stable transportation, designed to avoid formwork deformation during lifting.
6. Work Platform
Provides a safe, convenient workspace for workers during assembly, pouring and disassembly.
● Main Components: Pedal, platform support, folding guardrail and connecting brackets.
● Design Advantages: Pedal is installed at caster connection seats. Platform support fasten to main beams for stability. Folding guardrail uses a double-pin design—upper pins act as limiters, allowing easy opening for formwork demolding.
