Claims

[Scope of utility model registration request]

The hollow pile head 11 is held at the lower end of the holding member 20, and the pile 1 is held through the holding member 20.
A pile embedding device for burying a pile 10 in an excavated hole 1 includes a pressure contact member 30 inserted from the holding member 20 into the hollow pile head 11, and a pressure contact member 30 that expands and contracts in the radial direction of the pile 10. The pile embedding device is characterized in that it is provided with an operating means 40 for pressing the pressing member 30 against the inner surface of the pile head 11 and releasing the pressing member 30.
