摘要

PURPOSE: A retaining wall construction block, an assembled reinforced earth retaining wall built by the blocks and a construction method thereof are provided to cut down the material and construction cost by lightening the block, to reinforce a retaining wall body structurally after construction, and to repair a damaged part of the retaining wall easily. CONSTITUTION: A retaining wall construction block is composed of a front side(10) forming the surface of a retaining wall and a rear side contacting to the reinforced earth; left and right sides(30,30') having uneven combining units(32,32') corresponding to each other to uneven-combine the adjacent blocks; an upside(40) having stiffener-inserting grooves(44) formed in front and rear sides and fitted with a stiffener or an anchor for connecting the stiffener; a lower side corresponding to the upside; connection pin-inserting holes(h1) arranged on the upside and the lower side to combine connection pins between upper and lower blocks; a fixing groove(46) horizontally formed in the front both sides of the stiffener-inserting groove of the upside to fix the stiffener or the anchor; and pull-up pin inserting holes(h2) penetrated on the upside and lower side to insert pull-up pins for pulling up plural blocks at the same time. The connection pin-inserting holes are formed at left and right sides and the pull-up pin inserting holes are in the central part of the upside and lower side respectively.
