Abstract

PURPOSE: To reduce required power through minimization of resistance generated at digging holes by repeating a method wherein along with consecutive digging of holes by a device for digging, underground-steel materials are inserted and buried in the holes made in such a consecutive order on the occasion of successive laying of steel materials such as sheet piles in the ground.
CONSTITUTION: On a leader 7 erected in the front of a platform car 6 equipped with a device 5 for laying steel materials in the ground, a device 8' for digging holes prepared by setting an auger 4' inside of a casing pipe 3' is mounted as capable of going up and down and auger 4' is rotated by transmitted power. A laying hole A' is dug only by the auger 4' in the state that a sheet pile 1' is not fitted to a joint 9, and next, the leader 7 being shifted at a set distance, a hole B' bordering on the hole A' is dug out. Then, the auger 4' being pulled out from the hole B' and the leader 7 being shifted at the set distance, another pile 1' is fitted to the joint 9, and after that a hole C' is dug adjacently to the hole B'. At the same time, the pile 1', being engaged with the preceeding pile 1', is inserted into the hole B'. After digging is completed, the joint 9 is separated and the pile 1' is buried.
