Abstract

An air hammer drill device suitable for drilling a large diameter bore through a hard bed rock. The air hammer drill device is detachably provided at the bottom end portion (16) thereof with a plurality of bits (18), so that damaged bits are replaceable, thereby proving to be highly economical. Furthermore, the bits (18) are mounted to the bottom end portion (16) of the air hammer drill device through intermediate members (24, 34), whereby no shock waves from a piston ram are imparted to the members 34. Further, the bits (18) may be provided at the bottom end portion of the air hammer drill device (16) in a manner to be able to expand or shrink the boring diameter, whereby a simultaneous casing process and a shield process are carried out by use of this air hammer drill device. <IMAGE>
