Specific features of non-woven geotextiles used in tunnel projects

Specific features of non-woven geotextiles used in tunnel projects:

1. Tunnel waterproofing: On the inner wall and top of the tunnel, non-woven geotextile can be used as a waterproof layer. It prevents groundwater from seeping into the interior of the tunnel and avoids flooding and increased humidity inside the tunnel.

2. Tunnel drainage: In the tunnel foundation part, non-woven geotextile can be used to promote drainage. It can prevent the accumulation of groundwater and rainwater in the tunnel foundation, reduce the moisture content of the tunnel foundation, and maintain the stability of the foundation.

3. Tunnel anti-corrosion: Non-woven geotextiles can be used as anti-corrosion layers on the internal structure of the tunnel. It prevents moisture and chemicals inside the tunnel from corroding the structure and extends its service life.

4. Tunnel reinforcement: In the soil layer inside the tunnel, non-woven geotextiles can be used for reinforcement. It can increase the stability and compression resistance of the soil layer and prevent soil collapse and landslides.

5. Tunnel slope protection: Non-woven geotextiles can be used as slope protection materials on steep slopes or high slopes at the tunnel entrance and exit. It can prevent soil erosion and slope landslides and maintain the stability of the tunnel entrance.
