Abstract
PURPOSE: To maintain a heat insulation-cutoff function over a long period by a method wherein sprayed concrete of an excavated tunnel forms an outer layer and lining concrete is constructed on an inner surface having a heat insulation material and a waterproof sheet arranged in a layer. CONSTITUTION: Heat insulation materials 9, of closed-cell foams, previously formed in a block-form are stuck in an abutment state by using a drive gun on a wall surface 6 of sprayed concrete 4 sprayed on a tunnel inner wall 3 of a tunnel 1' excavated in a cold district. Thereafter, a waterproof sheet 13 is arranged in a layer-form along the inner peripheral surface thereof, and contact-bonded, and stuck by a waterproof sticking seal tape. Lining with given lining concrete 8 is lined on the inner surface of a waterproofing sheet 13. Thus prevents leakage of water from a ground 2 can be prevented and a fear of pooling water from icing and melting.
