<p>PURPOSE: An excavation system using water-jet and an excavation method using the same are provided to effectively prevent impact, vibration, and noise caused by blasting in an excavation process and increase stability of a tunnel by minimizing damage zones. CONSTITUTION: An excavation system using water-jet includes a movement unit(100), multi-joint robot arms(200), a water jet nozzle(300), a supply unit(400), and a control unit(500). The movement unit can move forth and back in an excavated direction on an excavated target section. The multi-joint robot arms are loaded on the movement unit. The water jet nozzle is mounted on the front end of the multi-joint robot arms. The supply unit supplies high pressure water to the water jet nozzle. The control unit controls the movement unit, the robot arms, and the water jet nozzle.</p> |
