Features:
- High Load-Bearing Capacity:
The integration of section steel and corrugated plates enhances the load-bearing capacity of the structure, allowing it to handle ultra-high fill conditions and heavy dynamic loads. This design is ideal for areas subjected to high static and dynamic stresses, ensuring long-term stability. - Elastic and Rigid Structure:
The combination of rigid and elastic structures in the arch design provides the flexibility needed to absorb and disperse forces evenly, significantly improving the overall strength and performance of the culvert. - Improved Structural Stability:
The addition of a steel frame—made of section steel and channel steel—inside or outside the original culvert structure improves the overall stability, particularly in low arch, door arch, and box arch configurations. The reinforced frame helps to distribute forces, ensuring the waveform of the corrugated plate remains stable under stress. - Enhanced Force Distribution:
The transverse reinforcement in the steel frame ensures that force distribution is even across the structure. This method converts point forces into line forces, and ultimately into net force, minimizing the risk of structural damage. - Versatility and Application:
This reinforced corrugated steel structure is versatile and can be used for a range of applications, including early tunnel support, bridge and culvert replacement, tunnel repairs, and maintenance of tunnel entrances and exits. It is also effective for snow protection, and is widely used in medium and small bridges, culverts, and other challenging environments. - Durability in Harsh Environments:
This structure is designed to withstand impact, vibration forces, and harsh environmental conditions, ensuring longevity even in extreme climates or areas with unstable soil. It provides a reliable solution for projects that require robust, long-lasting support systems.
Applications:
- Bridge and Culvert Replacement: Ideal for replacing or reinforcing existing structures.
- Tunnel Support: Provides early support and reinforcement for tunnel construction or repairs.
- Heavy Load and Impact Areas: Suitable for locations with heavy traffic or extreme environmental conditions.
- Snow Protection: Effective in protecting structures from heavy snow loads in cold climates.
- Reinforcement and Maintenance: Offers durable support for tunnel entrances, exits, and other critical infrastructure.
