  • Apparatus for and method of driving tunnels
    Patent number: 4451176
    Abstract: Apparatus for, and a method of, driving a tunnel utilizes a drive shield to support the forward end of the tunnel where debris material is removed. At the rear end of the drive shield, a lining is created to cover the exposed tunnel wall. This lining is produced by simply spraying concrete rearwardly directly between the space between multi-part formwork and the tunnel wall itself. The formwork may overlap with the drive shield. The formwork is advanced to follow the progress of the drive shield by removing part of the formwork from the rear and re-siting this part at the front end.
