Flexible tunnel shed is widely utilized in scenarios such as tunnel entrances and exits, roadside slopes, and mountain roadsides. The system consists of curved steel beams, supporting rods, ring nets, high-strength steel wire mesh, energy dissipators, on-site concrete foundations, etc. Mainly applied to prevent falling rocks from invading road clearance, the flexible tunnel system protects pedestrians, vehicles, and facilities on the road, especially around tunnel portals. Flexible tunnel shed systems can be divided into arch-type shed, frame-type flexible shed, and cantilever-type shed. The commonly utilized energy levels for arched flexible shed is 300 Kj, 500 Kj, and 800 Kj, and higher protection energy levels can be developed and designed separately according to demands.

Flexible Cantilever Shed is a variant rockfall interception system, which is horizontally installed on a near-vertical slope. After the falling rocks crash the flexible net, will move outside the protection area below by bouncing or rolling down, ensuring that the covered area is free from the hazards of rockfall. The same protection energy level as the normal rockfall mitigation system can be achieved, and rockfall clearance is usually not required. It can only applied to scenes of narrow areas close to the foot of the steep slope, such as cutting slopes, hillside roads, and roads near seashore cliffs. The serve energy level of the system is no less than 1,500kj.

The snow shed system is generally composed of components such as steel structural arches, diagonal support rods, snow-proof plates, and foundation supports. This system can effectively address issues such as wind-drifting snow and snow accumulation at tunnel entrances. Additionally, they can help to mitigate temperature differences between the inside and outside of the tunnel to reduce icing at tunnel entrances. Utilizing lightweight structures with minimal self-weight helps avoid extensive excavation and backfilling, resulting in slight ecological impact. Employing transparent snow-proof plate ensures good visibility and ventilation, promoting natural light and airflow at the tunnel gate. Integrating seamlessly with the surroundings, and forming a harmonious landscape.
