TUNNELLING SUCCESS FOR GROUT BAGS

A feature of the A27 south street road diversion tunnel construction at Lewes, Sussex, is the use of a grout bag system to pack the support arches. After excavation of the horseshoe section tunnel in chalk, steel colliery arches were erected and the polyester grout bags laid over the whole length of the steel arches and then pumped full of pozament grout containing an accelerator for early setting. An in-situ structural concrete lining follows erection of the arches which are subsequently cast in the mass of concrete. The lining was designed to take advantage of the inherent strength of the surrounding chalk.
