[0008] The cement mat 1 is made with a relatively high water content by making a slurry mainly composed of hydraulic cement and water by a paper making method. The powdery cement molding material 2 mainly composed of hydraulic cement whose water content does not exceed 50% is sprayed. When the upper surface of the cement mat 1 on which the cement molding material 2 is sprayed as described above is pressed, the cement mat 1 is first set below the press plate 4 as shown in FIG. As shown in FIG. 1B, the lower end of the surrounding weir frame 5 first comes into contact with the upper surface of the cement mat 1, and the press plate 4 is further lowered, thereby causing the weir frame 5 to contract. As shown in FIG. 1 (c), the upper surface of the cement mat 1 can be compressed by the concave-convex mold 3 on the lower surface of the press plate 4 to form an irregular pattern. Since the weir frame 5 contracts in this manner, no pressure is applied to the load on the cement mat 1 by the weir frame 5.
