GRAVITY TYPE PRECAST RETAINING WALL FOR HAVING SHEAR KEY AND STEEL PILE

摘要

PURPOSE: A gravity type precast retaining wall with a shear key and a steel pipe is provided to increase coherence between a cutting area and a precast retaining wall and to increase coherence between the precast retaining walls using a shear key. CONSTITUTION: A gravity type precast retaining wall with a shear key comprises a main body, a vertical wall, a first shear key(130), a second shear key(140), a guide tube, and an anchor guide tube. The vertical wall is integrated and expanded from the inner center of the incline of the main body to a bottom surface side. The first shear key, made of steel material in a hollow shape, is projected from the upper surface of an incline at the same angel as the incline. The second shear key is made of steel material in a hollow shape. The guide tube, made of synthetic resin or the metal material, is inserted between the first shear key and the second shear key at the same angle as the incline. The anchor guide tube passes through the vertical wall.
