Cut and Cover Tunnels are one of the oldest tunnelling methodologies which involve the digging of a trench/hill, construction of a tunnel, and providing appropriate backfill above the structure to bring it to its original state.
Cut and Cover Tunnels are of growing importance in the Indian infrastructure landscape. Their application has increased due to the increase in tunnelling activities in North and North-East India as new road alignments pass through existing mountain ranges. They are also actively used in the construction of underground railway/metro projects.
The LITHELYARCH® is positioned to be a suitable methodology for the construction of Cut & Cover Tunnels in both railway and highway projects. It performs as a superior alternative to cast-in-situ Boxes and RCC Arches with respect to time, cost, and maintenance, given that it is pre-cast and un-reinforced.
LITHELYARCH® Cut and Cover Tunnels can be designed to match the clients rise, span, foundation and drainage requirements with no restriction on tunnel length, alignment, or elevation. As an arch structure, there is no limit to the maximum load which can be applied on top of the structure, enabling it to be implemented in the toughest of terrains.
