The inner side of the insulating rock mud layer 6 is attached to the polystyrene board 41. The thermal insulation effect of the whole wall is increased by arranging the thermal insulation layer 2 between the outer wall layer 1 and the inner wall layer 3. During construction, the thermal insulation layer 2 is formed by splicing a plurality of composite thermal insulation modules 4.
