ROCK FILL CAUSEWAY FOR QUARRY ACCESS

A causeway, 12 M high and 130 M long has been constructed at an ICI quarry in Derbyshire. The causeway, which passes over British Rail and ICI tracks provides a 17 M wide road for dump trucks hauling rock from two high level tunnels. Two operations were involved; rockfilling to elevate the low-lying level of the railway embankment, and the construction of the two tunnels over the tracks in Armco super-span and a third giving vehicular access in Armco circular steel multi-plate. Both rail tunnels are mounted in reinforced concrete foundations. Each has been painted internally and externally with epoxy resin pitch and then wrapped with a corrosion protected membrane sealed to the foundations. A stringent backfill specification was needed as the structures depend on the reaction between the plate and surrounding backfill. A reinforced concrete thrust beam was cast where the side walls met the top arch to provide additional restraint. When completed, the causeway gives 5.8 M cover above the steel structures and is 12 M above the railway. (TRRL)
