In the field of tunnel construction, the efficiency and precision of small duct processing directly impact project quality and safety. As a professional manufacturer based in Heze, Shandong – China’s well-known engineering machinery manufacturing base, Xuhui (Shandong) Intelligent Equipment Co., Ltd. specializes in developing, producing, and selling automatic tunnel small duct production lines that meet international standards.
Our company has established itself as a reliable partner for global tunneling projects by combining advanced processing concepts with a team of technical experts and modern manufacturing facilities. We provide comprehensive standardized solutions for building steel reinforcement construction, particularly focusing on the specialized needs of tunnel engineering.
Core Product: Automatic Tunnel Small Duct Production Line
Our flagship product – the automatic tunnel small duct production line – represents the pinnacle of modern tunnel construction equipment technology. This fully integrated system is designed to perform three critical processes in one continuous operation: hole cutting, tip reduction, and end forming of small ducts used in tunnel support systems.
The production line features a modular design that allows for flexible configuration based on specific project requirements. With precision control systems and automated material handling, our equipment ensures consistent quality while significantly improving production efficiency compared to traditional methods.
Key technical parameters of our standard model include:
- Processing range: Φ42-108mm small ducts
- Hole cutting accuracy: ±0.5mm
- Tip reduction precision: ±0.3mm
- Production capacity: 800-1200 pieces/shift (8 hours)
- Power consumption: 380V/50Hz, total power about 45kW
- Control system: PLC + touch screen operation
For international projects with specific requirements, we offer customized solutions that can be adapted to different duct sizes, hole patterns, and production volumes. Our engineering team works closely with clients to develop optimal configurations that meet both technical specifications and budget constraints.
Technical Advantages of Our Production Line
What sets Xuhui’s tunnel small duct production lines apart from competitors are several key technical innovations:
1. High-Precision Processing System
The equipment incorporates advanced CNC technology with servo motor control for all moving parts. This ensures millimeter-level precision in both hole cutting and tip reduction processes, which is crucial for maintaining the structural integrity of tunnel support systems.
The hole cutting unit uses specialized carbide tools that maintain sharpness for extended periods, reducing tool change frequency and improving production continuity. The tip reduction process employs a multi-stage forming approach that prevents material deformation while achieving the required dimensional accuracy.
2. Fully Automated Operation
From material loading to finished product unloading, the entire production process is automated. The integrated conveyor system smoothly transfers ducts between processing stations, eliminating manual handling and reducing the risk of workpiece damage.
The PLC control system stores multiple processing programs that can be quickly selected based on different project requirements. Operators only need to input basic parameters, and the machine automatically adjusts all processing parameters accordingly. This simplifies operation while ensuring consistent quality across different production batches.
3. Safety and Reliability Design
We prioritize operator safety in all our equipment designs. The production line features comprehensive safety protections including:
- Emergency stop buttons at multiple locations
- Protective enclosures around moving parts
- Automatic shutdown when safety doors are opened
- Overload protection for all motors
- Visual and audible alarm systems
The mechanical structure uses high-strength steel components with precise machining to ensure long-term stability under continuous operation. Important transmission parts are equipped with automatic lubrication systems to reduce wear and extend service life.
Application Scenarios and Project Cases
Our automatic tunnel small duct production lines have been successfully deployed in numerous tunneling projects worldwide, including highway tunnels, railway tunnels, and urban metro systems. The equipment is particularly valuable in projects with:
- Large-scale tunnel networks requiring standardized support components
- Complex geological conditions demanding precise support system installation
- Tight construction schedules requiring high production efficiency
- Strict quality control standards for tunnel safety
| Project Type | Application Benefits | Efficiency Improvement |
|---|---|---|
| Highway Tunnel | Standardized duct production ensures consistent support quality across long tunnel sections | 300% faster than manual processing |
| Railway Tunnel | High-precision ducts meet strict safety requirements for high-speed rail tunnels | Reduced labor cost by 65% |
| Urban Metro | Compact equipment design fits limited construction site space | 24/7 continuous operation capability |
One notable project was the Jakarta-Bandung High-Speed Railway in Indonesia, where our equipment produced over 50,000 small ducts with 100% acceptance rate during quality inspections. The client particularly appreciated the consistent hole patterns that simplified subsequent installation work and improved overall tunnel stability.
Global Export and Certification
As a manufacturer with international vision, Xuhui has obtained CE certification for all our tunnel small duct production lines, ensuring compliance with European safety, health, and environmental protection standards. This certification has opened doors to markets in Europe, Southeast Asia, the Middle East, and other regions.
Our export services include:
- Customized voltage and frequency configurations for different countries
- Multilingual operation manuals and safety guidelines
- CE compliant electrical system design
- Export packaging meeting international shipping standards
- Assistance with customs clearance documentation
For projects requiring special certifications, we work with authorized third-party inspection agencies to conduct additional testing and certification processes, ensuring our equipment meets all local regulatory requirements.
Comprehensive After-Sales Service
