PROBLEM TO BE SOLVED: To provide a laying method of a concrete block which can improve safety when forming a concrete block on a bank slope and perform efficient installation.SOLUTION: A first slope concrete block 11 has a substantially-rectangular flat shape consisting of an upper face, a lower face and four side faces. Height adjusting tools 21a and 21b are screwed on the bottom face of the first slope concrete block 11, a horizontal adjusting tool 22a is screwed to the lower side face of the first slope concrete block 11, and a downward protruding part 26a with a trapezoidal shape in a plan view is formed on the lower part of the upper side face so as to protrude upwardly. With a laying method of a concrete block having this configuration, safety is improved and efficient height setting can be performed because the height adjusting tools 21a and 21b are screwed to the lower face of the first slope concrete block 11 at the time of placement on leveling concrete 69 on a bank slope. |
