Abstract
PURPOSE: To exactly remove an under pile by a method in which a steel material is inserted down to the under pile of existing concrete joint pile, the lower end of the steel material is fixed to the under pile by cement mortar, etc., and the steel material is drawn out.
CONSTITUTION: The ground is excavated until the head of a pile A is exposed, the hollow portions of the pile are connected with each other in case where the joints of the pile A is closed by concrete, etc. Then, a drawing steel material 2 is inserted into the hollow portion of the lower pile A, and a mortar, e.g., expansive concrete, etc., is injected. At the same time, an injection pipe 3 is inserted and the drawing steel material is fixed to the under pile A1 as the motor 4 hardens while drawing out the injection pipe 3. Furthermore, a steel pipe 5 is inserted by driving into the ground surrounding the pile A for separation. After the processes, the upper pile A2 is first drawn out, the drawing steel material 2 is then pulled, the lower pile A1 is removed, and the pipe 5 is drawn out while back filling the hole.
