摘要

Southam quarry in Warwickshire, UK, supplies clay and limestone to a nearby cement works in Rugby. A new conveyor tunnel completed in 2017 will ensure its continued operation for a further 28years. The 60m long, sprayed-concrete-lined tunnel under the A426 highway houses part of a new 1 km long conveyor system that now transports 2500t/day of quarried material to the processing plant. Construction of the tunnel was undertaken in a busy quarry environment and under a live highway. The design and construction of the tunnel and its two engineered portals are described in this paper.
