摘要： PURPOSE:To shorten a driving time of a pile, by a method wherein, after a steel pipe pile is vertically self-erected at a vibro chucking self-erecting base, a vibro hammer is attached to the upper end of the pile through the medium of a chucking guide. CONSTITUTION:After a looped wire 2 is stretched around a long steel pipe pile 1 and is engaged with a hook 4 of a crane 8, the pile 1 is hung down by means of a crane 3 to carry it to a vibro chucking self-erecting base 5 to vertically self- erect it. A chuck 7 located to the lower end of a vibro hammer 6 is hung down to the upper end of the pile 1, and the pile 1 is mounted to the hammer 6 through a chuck guide. After the hammer 6 and the pile 1 are hung down by means of the crane 3 and are carried to a pre-excavated hole 9 previously excavated to hang it down thereinto, the pile 1 is driven with the aid of the hammer 6.

摘要： PURPOSE:To enable even the hoop of a large size to be easily bent and secured to the outside circumference of main reinforcing steel by slewing a knuckle plate around the axis by way of links by a hydraulic cylinder. CONSTITUTION:A hoop B which is bent to a hook shape at one end is hooked to main reinforcing steel A, and is wound, after which the other end is bent and is secured to the other main reinforcing steel A. In this case, a hook fitting 12 is set to the reinforcing steel A in the end position of the hoop B and the reinforcing steel A adjacent to this reinforcing steel A, and the end of a knuckle plate 9 or a roller 11 is placed along the end of the hoop B. Next, a hydraulic cylinder 3 is operated to push out a rod 21a and oscillate it with a link 5 and axis 4 as a fulcrum. The stroke of the cylinder 3 is then increased by the link 5 and is transmitted to a link 7 without giving any undue force to the projecting direction of a rod 2 to slew the plate 9 around the axis 8, thereby bending the hoop B on the outside circumference of the reinforcing steel A at a normal angle and detaining the same thereto.
