A row of second water drain pipes are further arranged on the bottom face of the third heat preservation layer at intervals, peripheral seams of pipe openings in the upper ends of the second water drain pipes are sealed through sealing paste, and the lower ends of the second water drain pipes extend out of the bottom face of the reinforced concrete roof board. An extruded polystyrene board and polymer mortar are sequentially laid on the outdoor bottom face of the reinforced concrete roof board, and a layer of glass fiber-resistant gridding cloth is pressed into the polymer mortar. Through the combination of modern building materials and ancient design concepts, the antique sloping roof of the wall body is firmer, the construction quality is improved, and the repair rate is reduced.
