摘要	PURPOSE: To establish a simple boring device by coupling a water pressure supply pipe to a control device of a thrust unit, and further to a hammer drill, and using a flush water for hammer bit as the power for driving the drill. CONSTITUTION: A water pressure supply pipe 6 is coupled with a thrust unit 10 equipped with a control device 14 having a rotary slide valve and a hydraulically driven hammer drill 1. Further the control device 14 and hammer drill 1 are connected together through a single pipe 5. The thrust unit 10 and hammer drill 1 are driven with a high pressure water fed from the supply pipe 6, which is used as flush water for drill bit 3 so that a release circuit is formed to eliminate necessity for any return pipe. Thereby the device is simplified and the operation is facilitated. COPYRIGHT: (C)1991,JPO
