PROBLEM TO BE SOLVED: To eliminate a dislocation or a separation for providing the quickness of a work by attaining a surely combined state, provide a retaining wall block combination structure improving free-standing stability and enhancing the safety of the work, and further provide a retaining wall construction method capable of reducing construction cost. ;SOLUTION: Retaining wall blocks 3 are spread all over a slope S along a road, a river, a coast, a railroad track or the like in both vertical and horizontal directions for the coverage thereof. In this case, the upper and lower surfaces of each retaining wall block 3 are inclined at the prescribed angle with a horizontal plane, and a combining projection 7 is formed on the upper surface of the retaining wall block 3, so as to be vertically extended and projected. Furthermore, a combining recess 8 is formed on the lower surface of the retaining wall block 3 so as to be coupled to the combining projection 7, and through-holes 10 are formed on the combining projection 7 and recess 8. In addition, a drain pipe 11 is laid so as to penetrate the through-holes 10 of the combining projection 7 and recess 8 kept in such a state as coupled to each other.;COPYRIGHT: (C)1998,JPO
