Waterproofing Sprayed Concrete Linings - Existing Methods ...

Sprayed Concrete Tunnels are a popular solution to the increasing need for fast and efficient transport systems in urban environments worldwide. For shorter tunnels (less than 1km long) with varying geometry and junctions, the use of a sprayed concrete lining (SCL) is an efficient and cost-effective construction technique.

What are the differences between segmentally lined tunnels ...

The basic difference between segmentally lined tunnels and SCL tunnels is that the sprayed concrete in SCL tunnel is used for temporary linings only. Concrete linings in segmentally lined tunnels are designed with long-term load conditions with the adoption of appropriate safety factors. However, the dimension of linings in SCL tunnels is derived from a []
