ROTARY PILE PENETRATING APPARATUS

PROBLEM TO BE SOLVED: To provide a rotary pile penetrating apparatus which is light in entire weight, and can be transported by a trailer without disassembling the apparatus. SOLUTION: A first guide cylinder 5 is installed in parallel with an axial center of a steel pipe pile 1, at a location of an elevating frame 6 which is outside the installation location of an elevating cylinder 7, and a second guide cylinder 4 is installed on a base frame 2 so as to be arranged in the internal periphery of the first guide cylinder 5. Then, a horizontal jack 1 for adjusting the height of the base frame 2 is arranged on a coaxial cable of the second guide cylinder 4, and a fourth guide cylinder 11 is arranged on a coaxial cable of a chuck cylinder 9 at a location of the elevating frame 6 which is inside the installation location of the elevating cylinder 7. Further, a third guide cylinder 10 is installed on an upper frame and on the internal or external periphery of the fourth guide cylinder 11. In this manner, the rotary pile penetrating apparatus is constructed.
