COMBINATION STRUCTURE OF PRECAST PANEL FOR PAVEMENT AND ITS METHOD

摘要

PURPOSE: A structure and a method for coupling precast panels for road pavement are provided to prevent damage to a panel body when the panel body is conveyed and installed. CONSTITUTION: A structure for coupling precast panels for road pavement comprises panel bodies(11a,11b) and coupling units(20). The panel bodies are installed in a road. The coupling units are installed in the panel bodies so that the panel bodies can be coupled to the other panel bodies. Each coupling unit comprises a first pipe(30), a second pipe(40), a connection bar(50), and a grouting material. The first pipes are installed in the inner edge of the panel bodies and have injection ports(31). The injection ports are upward extended. The second pipes are installed in the inner edge of the other panel bodies. The connection bars inserted into the first and second pipes. The first and second pipes and the injection ports are filled with the grouting material.
