RETAINING WALL STRUCTURE USING PERMANENT ANCHOR AND PRECAST CONCRETE PANEL, AND CONSTRUCTION METHOD OF RETAINING WALL FOR IMPROVING RESISTING POWER AGAINST EARTH PRESSURE ADDED ON PRECAST CONCRETE PANEL

摘要

PURPOSE: A construction method and a structure of a retaining wall using a permanent anchor and a precast concrete panel are provided to improve the resisting power against the earth pressure added on a precast concrete panel by fixing a permanent anchor to the ground and to restrain the movement of the ground by the improved resisting power. CONSTITUTION: The construction method for a retaining wall(100) using a permanent anchor and a precast concrete panel comprises the steps of: leveling up the ground along a boundary for constructing the retaining wall(100), then cutting off an inclined ground; locating a panel(130) provided with a hollow(131) on the leveled ground(111); perforating the inclined ground(113) to gradually be inclined downward toward the inside of the inclined ground(113) against the horizontal direction of the earth pressure added on the panel(130); inserting an anchor(120) into a perforated-inserting hole of the inclined ground(113), then anchoring the rear end of an anchor(120) to the inserting hole of the inclined ground(113); tensioning the anchor(120); fixing the front part of the tensioned anchor(120) to the panel(130); and banking up between the panel(130) and the inclined ground(113).
