PURPOSE:To raise the efficiency of operations as well as to save manhours to be required by a method in which a bilaterally inclined connecting block having a projected T-shaped stay is formed on a back side where mirror portions inclined toward the front side are set in parallel and they are fitted with each other in upper and lower stages. CONSTITUTION:An oblong mirror face of reinforced concrete is inclined at about 45 deg. from the right upper side to the left lower side, and a flat plate stay 2 is projected from the back, side, and central positions of many right-handed inclined mirror portions 1a connected bilaterally. A slopped face inclined from the front end to the back end is formed on the upper and lower sides of a receiving portion 3 projected vertically in a sideways turned T-shaped form on the back end of the stay 2. The left-handed inclined block 6a is fitted with the upside of a footing block set on the foundation concrete placed on the ground, and left- and right-handed inclined blocks 6a are alternately fitted with each other in vertical stages to stack them up. The construction work can thus be simplified and the efficiency of operations can be enhanced.
