Flexible Tunnels

A flexible protective system consisting of a steel structure combined with a flexible mesh, primarily used at tunnel entrances and exits and high-side slope roadbeds to prevent falling rocks. The system is categorized by energy levels, offering protective mesh systems with impact resistance of 500 kJ, 750 kJ, 1000 kJ, and 1500 kJ.

A flexible protective system primarily used at tunnel entrances and exits, and at high边坡 roadbeds to protect against falling rocks, constructed with a steel structure and combined with flexible mesh.

Three: Advantages, Applications, and Composition

Advantages:

Construction Period: Significantly reduces the construction time compared to conventional tunnel excavation, reinforcement, formwork, demolding and curing, and decoration work.

Cost Management: Saves approximately 10% in costs compared to conventional reinforced concrete tunnels.40-50%。

System Compatibility: This system, when paired with conventional active and passive netting, effectively mitigates the hazards posed by falling rocks within the operating range to both vehicles and pedestrians.

Post-maintenance: Long-term product environmental corrosion can be resolved by simply replacing a single component.

Structural composition

Steel Structure: Used to suspend and support cables to transfer the load energy absorbed by the flexible mesh to the ground.

Support rope: Supports and transmits the load energy of flexible net through prestressed tensioning.

Flexible annular mesh and diamond-shaped small mesh: bear the direct force of falling rocks.

Broad Application

Tunnel entrance and inter-tunnel geological disaster prone areas

Highly prone area for rockfalls on steep slopes

Shorter-term emergency rescue project
