PURPOSE:To improve safety of a pile driving work and to improve working efficiency, by a method wherein a platform with a crane is placed on precast piles through a running device, and after driving of the pile with the aid of a crane is completed, the platform is moved in a running state. CONSTITUTION:Running devices 5a and 5b are respectively spanned between 2 sets of precast piles 3a, and a platform 6 is placed on the running devices 5a and 5b. A crane 7, hanging and vertically conveying a pile and hanging and holding a hammer 4, is disposed to a platform 6. After driving of the pile 3b is completed, another running device is spanned between piles 3b, and the platform 6 is moved forward through driving of the running devices 5a and 5b. After the platform 6 is supported to the piles 3b through another running device, the running device 5b is removed. This causes supporting of the platform 6 to the piles, resulting in improvement of safety of a pile driving work, and improvement of working efficiency. |
