发明名称 A ROCK SPLIT DEVICE WITH NO-VIBRATION CONDITION USING FLUID PRESSURE
摘要 A rock split device with no-vibration condition using fluid pressure is provided to improve workability and reduce construction cost by simultaneously inflating various tubes using high fluid pressure. A rock split device with no-vibration condition comprises an element(100) which is installed in an inner side of a thruhole. The element(100) generates inflation pressure as fluid pressure is applied thereto. The element(100) includes a fluid supply pipe, a plurality of tubes(130) and a fixture member. The tubes(130) are installed on the fluid supply pipe and spaced apart from each other. The fixture member includes a connection rod, and a first fixing unit and a second fixing unit. The first fixing unit generates frictional force at one surface of the connection rod.
