Abstract: PURPOSE: A block for constructing a reinforced earth retaining wall is provided to keep the shape of a retaining wall in the same shape constructed initially by preventing an upper block from being pushed by earth pressure, to prevent a crack of a block caused by concentrated stress by dispersing stress by earth pressure. CONSTITUTION: A block for constructing a reinforced earth retaining wall comprises: a block body(20) containing a pair of oval pockets(26)(26') formed inward from both sides(24)(24') and a pin holding groove(27) formed to cross both sides(24)(24') on the lower side(23) of the block body(20) ; and a block connector(30) connecting upper and lower blocks constructed to be overlapped and containing a pair of oval couplers(31)(31') interposed to the pockets(26)(26') and connecting pins(32)(32') projected upward from the couplers(31)(31'), where the projected parts are interposed to the pin holding groove(27).
