To provide a temperature control method which is effective and adequate for controlling the temperature of a young-aged lining concrete in a tunnel construction.
A heating sheet is attached to a concrete form for placing and molding lining concrete in advance, and the surface temperature of the lining concrete is measured after the lining concrete is placed in the concrete form. When the surface temperature reaches a peak temperature, a surface layer part of the lining concrete is heated by the heating sheet via the concrete form and a heating/curing time for reducing a temperature difference between an internal temperature and the surface temperature is secured by preventing a sudden drop of temperature in the surface layer part. Thereafter, the concrete form is removed.
