(54) A block for constructing reinforced earth wall


(57) Disclosed is a block for the construction of a reinforced soil segmental retaining wall. The block includes a front surface (20), a rear surface (20), left and right lateral surfaces (30 and 30'), an upper surface (40) having a pair of left and right reinforcement insertion grooves (44), and a lower surface (50) opposite to the upper surface (40). A pair of anchor pin insertion bores (h) extend vertically at left and right sides of the upper and lower surfaces (40 and 50) so that anchor pins (P) are inserted therethrough to connect vertically neighbouring blocks. Also, a pair of through-passages (60) extend vertically from the upper surface (40) to the lower surface (50) to be laterally spaced apart from each other by interposing a partition (52). The through-passages (60) are located to lock the anchor pins (P) inserted through the anchor pin insertion bores (h) of overlying blocks. The reinforcement insertion grooves (44) are located at opposite sides of the through-passages (60) so that the leading end of the reinforcement (80) is directly fitted through the insertion grooves (44) while coming into contact with front ends of the through-passages (60). Another reinforcement insertion groove (44') is formed along the front end of the partition (62) so that the middle portion of the reinforcement (80) is fitted to allow the reinforcement (80) to extend rearward through the reinforcement insertion grooves (44).
