<p>The present invention relates to an excavation apparatus to install precast concrete (PC) boxes, and the main purpose of the present invention is to bury the PC boxes in the ground without blocking the roads and to prevent the PC boxes from breaking while they are handled by means of a crane. The excavation apparatus to install the PC boxes comprises: a main body which includes an end cap provided on an interior place at a certain distance apart from the quadrangular tubular front; at least one vibration device radially provided on the front interior of the main body to make excavation easy; and a transport device provided to transport the stuffs produced from the excavation. Accordingly, the excavation apparatus to install the PC boxes allows the PC boxes to be buried in the ground without blocking a road, prevents them from breaking while they are handled by means of the crane, and dispenses with bed excavation and refilling processes; thereby increasing productivity of the excavation.</p> |
