he junction surfaces of the joints can be either flat inclined surfaces (31 a) or curved slopped surfaces (31 c) or stepped surfaces (31 b) as shown on Fig. 7. Preferably these joints are progressively more globally inclined joints from the center toward the periphery of the bottom lining, an important aspect being that the border of any block directed toward the axis A is surmounting the adjacent border of the adjacent block, so that a sort of arching effect, favorable to a better maintain of the blocs, is obtained by blocking successively the different rings from the center to the exterior ring.
