Segmental Tunnel Linings
Adfil Macro & Micro Synthetic Fibres can be used in precast Segmental Linings to replace conventional steel mesh.
Tunnel segments & Pipes have had fibres used as reinforcement for many years, using Micro, Macro and Steel fibres. But the most commonly used reinforcement is steel mesh and steel bar. The advantage of Polypropylene fibres is that they are none corrosive and give advantages in segments & pipes used in underground applications where water ingress is possible. Due to the importance of reinforcement placement in these applications, the use of fibres gives the advantage of correctly placed reinforcement throughout the cast. Also, production is increased which is an important factor in supplying this type of contract.
Advantage
- Reduced manufacture costs
- Reduced Transport costs
- Guaranteed placement of the reinforcement
- Impact & Abrasion improvements
- Reduced Co2 emissions
- Not susceptible to corrosion
