Zusammenfassung:	PURPOSE:To carry out simultaneous stable supplying of a number of excavation shafts and perform spliced piercing of them while avoiding increase of the device weight and size. CONSTITUTION:In a shaft accommodation device 14, excavation shafts 16 are accommodated in rows in the piercing arrangement direction and accommodating arrangement direction. One row of excavating shafts 16 in the piercing arrangement direction are held by a rod carrier 26 in the condition that their tops 16a are exposed to the over. This rod carrier 26 is run along a guide rail provided fore and aft on the shaft accommodation device 14, and thereby simultaneous supply of the excavation shafts 16 is conducted till the position of piercing made by a shaft piercing/drawout device 18 while they are put in parallel movement.
