A retaining wall block is provided to extend service life and to increase constructability by piling up blocks bodies using coupling projections and coupling grooves and attaching an exterior body on the block body using adhesives. The retaining wall block(100) contains a block portion(110) and an exterior portion(120). The block portion contains a coupling projection(113) formed at a right angle to the center of an exterior plane(112) formed on the outside of a block body(111) piled in a crossing direction to form a retaining wall, plural coupling grooves(115) formed on the upper part of the block body, coupling pins(114) inserted to the coupling grooves to be projected upward and a long coupling groove formed on the lower part of the block body and fitted with the coupling pin, and the exterior portion contains a fixing groove(123) formed on an exterior body(121) attached to the exterior plane of the block portion to be coupled in the corresponded shape to the coupling projection of the block portion and an adhesion joint(122) formed on the rear of the exterior body to be attached on the exterior plane of the block body. |
