PURPOSE: To increase the strength and enable a sufficient strength to be obtained even in the use of thin lining materials by filling mortar in a wave-shaped groove made of steel-plate lining element and installing said element on a concrete wall.
CONSTITUTION: A plural rows of wave-shaped grooves 5 are made of steel-plate lining element 4 by means of force plunger to increase the rigidity. After mortar 6 is filled and adhered in the wave-shaped groove 5 of each steel-plate lining elemnt 4, said steel-plate lining element 4 is fixed by setting a wave-shaped groove 5 lengthwise and allowing said wave-shaped groove 5 to be oriented to the concrete wall surface. In order to fix the steel-plate lining element 4 on the concrete wall surface, a metal fitting 7 is embedded beforehand on the concrete wall so as to fit for the dimension of each steel-plate lining element 4, and the steel-plate lining element 4 is welded onto the metal fitting 7 and fixed
