Abstract
Abstract A device for excavating a tunnel and lining it with concrete is formed of a scaffolding member located at the working face and followed in series by a support structure and a concrete form assembly. The scaffolding member has collapsible working platforms which can be arranged vertically across its front end to provide protection during the blasting operation. The support structure includes means for conveying excavated material to a plurality of temporary storage hoppers located within the form assembly and a conveying system for supplying concrete into the forms. Portions of the form panels can be extended laterally outwardly to assist in the removal of any temporary support required for the tunnel.
