Abstract

PURPOSE:To enable formation of a large-diametered consolidated sand pile by us of a small-diametered hollow pipe by consolidation of sand in vertical direction and consolidation of sand in horizontal direction. CONSTITUTION:In the lower portion of a hollow pipe 1 for forming a sand pile, there is disposed an impact rotation generator 7 which transmits impact rotational forces to an impeller drive shaft 11 intermittently by use of compressed air 6. The impeller 10 has a plurality of arch-shaped vanes and projects from the lower end of the pipe 1. The generator 7 comprises an air motor 15, rotary frames 26a and 26b, a drive shaft 25 fitted with a projection plate 27, an impact element 35 fitted to a pin 34, and the like. The work is conducted by rotating the impeller 10 by the high-speed rotation of the air motor 15, while applying intermittent impacts to the impeller 10.
