BLOCK FOR REINFORCED EARTH WALL

摘要

A block for constructing a retaining wall is provided to prevent the blocks from being slid according as the laminated projection and the combining hole are mutually interlocked. A block(B) for constructing a retaining wall is composed of a front surface(10) exposed to the outside; a rear surface contacted at the reinforcement earth body; laminated projections(32); an upper surface(30) formed with a combining hole(34) where the laminated projection is fitted and interlocked; a lower surface(40) contacted at the upper surface; and left and right surfaces(60) adjacent to left and right sides and contacted between the blocks. The laminated projections are each installed at both left and right sides and the rear center of the upper surface of the block. Pulling-up grooves(52,62) are installed in the block at the rear part of the left and right surfaces and extended from the upper surface to the lower surface. A U-shaped reinforcement insertion groove(36) is opened to the rear surface at the upper surface. A fracture groove(72) is formed at a wing unit(70) formed at both sides of the rear side of the block by the pulling-up grooves. The wing unit is detached along the fracture groove.
