A prefabricated precast concrete culvert is provided to decrease the process of assembly of a PC culvert remarkably by arranging an anchorage of the starting point parallel to an anchorage of the end point. A prefabricated precast concrete culvert comprises a culvert, a wedge cone(2) having a wedge hole whose cross section is contracted gradually, and a pipe installed to the contraction section of the wedge hole to form a steel wire insertion hole, wherein the wedge cone includes wedge holes(17,27) formed parallel to the wedge hole and having the cross section expanded gradually, wedges(11,21) arranged in the wedge holes, elastic members(12,23) applying elastic force to the wedge toward the contraction section of the wedge holes, and a finish plate closing up the expansion section of the wedge holes. |
