To provide a loading implement for a rapid loading test of a pile, which does not require a large-scale apparatus as in a case of a heavy weight drop method, hardly causes noises nor ground vibrations, and has no need of using a cushioning material.
The loading implement 1 is placed on a pile head to execute the rapid loading test of the pile. The loading implement 1 has a case 2, in which an upper chamber 4 and a lower chamber 5 are formed by demarcation, both chambers communicating with each other via a small hole 3. The lower face of the upper chamber 4 is an annular sloped surface 6 which slopes down from the outer periphery side to the small hole 3, while the upper face of the lower chamber 5 is an annular sloped surface 7 which slopes up from the outer periphery side to the small hole 3. The case 2 contains a number of weight materials, such as weight balls 8, which fall from the upper chamber 4 into the lower chamber 5 through the small hole 3 one after another, and is provided with a slidable shutter 10 for opening/closing the small hole 3.
