<p>PURPOSE:To prevent penetrative corrosion from a joint part without using a joint material by forming a two-layered structure consisting of a fixedly adhered lining layer of a silica type block material and a non-adhesive lining layer of a gripping and fixing non-adhesive block material on a lining layer comprising a rubber or a rubber like substance. CONSTITUTION:On the lining layer of a gas cooling tower, a fixedly adhered layer formed by adhering and fixing heat and chemical resistant fixing silica type block materials 7 based on silica with a silica type joint material 8 is set. Especially, to a most easily damaged region in the vicinity of the upper part of the cooling tower into which a high tamp. gas is introduced, support silica type block materials 10, 11 are provided to the upper and the lower parts of the fixed lining layer in this region and non-adhesive silica type block materials 9 stacked in a non-adhesive condition are grasped and fixed by the support silica type block materials 10, 11. By this method, a two-layered structure consisting a fixed lining layer and a non-adhesive lining layer comprising the silica type block material is set.</p> |
