(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).
