description PROBLEM TO BE SOLVED: To eliminate the need for the selection of a place because a low bed type turning device is used, to simply exchange and use screw drilling and down the hole hammer drilling quickly and to efficiently excavate a ground by using an excavation means fitted for the ground and geology. SOLUTION: The turning device 1, to which a center-hole revolution body 5 in which an engaging section for a clutch conducting common engagement with a casing 3 and a screw blade 20 is formed to the internal surface of a hole is mounted, is installed, and a down the hole hammer 2 and an auger screw 18 are set to the turning device 1 in an exchangeable manner as required and excavation is conducted.
