Development of an Extruded Tunnel Lining System
The objective of this report was to design, develop, fabricate, test and demonstrate a system for placing a continuously extruded tunnel liner. The Extruded Tunnel Lining System (ETLS) is a process for continuous slipforming of a concrete tunnel lining directly behind a tunnel boring machine. The program was carried out in three phases. This present report describes the results of the work conducted during Phases II and III (July 1979 - June 1983). It includes the design, fabrication and evaluation of a full-scale, 10-foot diameter in an above ground tunnel test facility. Data have included mechanical loading on ETLS components due to form drag, buoyancy, and deviation from alignment; concrete pressures and concrete strength/time properties; and behavior of the ETLS control system. These have been incorporated into a conceptual design for the first underground ETLS.
