Abstract

PURPOSE:To prevent the deterioration of concrete without the contact of the steel fiber of concrete surface with air by covering the concrete surface with a sheet, while a frame has been clothed in said sheet. CONSTITUTION:A frame 1 is annually assembled inside of the tail part of a shielding machine. Steel fiber concrete 8 is fed and placed in between the frame 1 and the tail part from the feeding port provided in a bulkhead ring 7 accompanied by the propelling of the shielding machine. Then, the concrete 8 intrudes around and between brushes and adheres to a sheet 2 without forming of clearance. After the concrete 8 has been hardened, the frame 1 is released, at that time only the frame 1 is separated in the state where the sheet 2 adheres to the concrete 8. The lining wall having been made of the steel fiber concrete 8 prevents the deterioration of the concrete, since the surface of the concrete is covered with the sheet 2, and is not in contact with air.
