Abstract
PURPOSE: To suppress the generation of vibration and noise as much as possible by an excavation method in which excavation is proceeded by inserting a pile into a casing to which a steel pile head whose lower end is provided with a spiral projection is attached.
CONSTITUTION: A hexagonal and conical head 1 is formed by attaching a steel plate 4 having a spiral projection 5 on its outside to a base 2 in a freely opening or closing manner by means of a hinged plate 6. The head 1 is attached to a casing 21, a pile 20 is inserted into the casing 21, a driving device 22 is connected to the top of the casing, and then the casing 21 is turned to advance excavation down to a given depth. The pile 20 is pressed on the bottom of the casing 21 by means of a pressing mechanism 24, a cement milk 25 is injected, the casing 21 is reversely turned, and a cap 7 is pushed out. Then, the cap 7 is left behind under the ground, the casing 21 is pulled up, and the space around the pile 20 is filled with the cement milk and solidified.
