PRECAST CONCRETE RETAINING WALL BLOCK

摘要

PURPOSE: A precast concrete retaining wall block is provided to quickly and accurately assemble the front linearity and total level of the retaining wall block assembled and installed at the spot, to stably mount the lower end of the retaining wall block, and to easily perform sliding operations of the block for precisely setting the front linearity of the retaining wall. CONSTITUTION: A precast concrete retaining wall block(100) formed in an L shape or a reverse T shape is composed of a bottom plate(10) horizontally put on a base unit at which a retaining wall is mounted; a vertical wall(20) set up on the bottom plate; a plurality of nut pipes(11) vertically mounted at the bottom plate to hold the gravity center of the retaining wall block in balance; a plurality of leveling bolts(12) assembled to the nut pipes to vertically move and adjust the verticality and horizontality of the retaining wall block; and at least one concrete input port(13) arranged at the predetermined position of the bottom plate to vertically pass through the bottom plate. The lower side of the leveling bolt is contacted to the upside of the base unit to support load of the retaining wall block and formed in a round shape to point-contact to the upside of the base unit.
