PRECAST BLOCK WALL, CANTILEVERED SLAB BRIDGE USING PRECAST BLOCK WALL AND CONSTRUCTION METHOD THEREOF

摘要

PURPOSE: A precast block wall, a cantilevered slab bridge using the precast block wall, and a construction method thereof are provided to prevent the deformation of a retaining wall due to the differential settlement of a back fill section by unifying the movement of blocks for forming into a bearing wall. CONSTITUTION: A precast block wall comprises a front wall(110), an internal pillar(120), reinforced earth(130), and a reinforcing material(140). The front wall is made of the layers of precast blocks equipped with a hollow part on the top of a foundation(101). The hollow part is embedded with the internal pillar. The rear side of the front wall is filled with the reinforced earth. The rear side of the front wall is horizontally installed with the reinforcing material according to the layered height of the precast blocks. The front wall alternately forms each layer in order to fit the hollow part and groove of the precast block. The internal pillar is equipped with re-bars(121) in the hollow part and filled with mortar(122).
