Non-vibration tunnel excavation method and non-vibration tunnel excavator

摘要

The present invention discloses a non-vibration tunnel excavation method and a vibration-free tunnel excavation apparatus. The present invention relates to a tunnel excavation method for excavating a tunnel of a tunnel, which is simple and inexpensive and can be easily excavated without causing noise, because it is installed in a heavy equipment such as a fork- And a non-vibration tunnel excavation apparatus. The above object of the present invention can be achieved by an airbag apparatus comprising: an arm engaging portion engaged with a front end of an arm of a construction heavy equipment such as a forklra; a bearing portion rotatably engaged with the arm engaging portion; And a crushing blade installed in the support cage in a floating state by a connecting means such as a chain or a steel rope and provided with a crushing blade for crushing the rock mass. A step of boring a horizontal hole close to the horizontal, a step of bringing the tunnel excavation part including the arm coupling part provided to be coupled to the arm of the forklain into close proximity to the horizontally perforated horizontal hole, Rotating the crushing part at a predetermined angle through the bearing part to rotate the horizontal hole and the center so as to be in contact with each other; A step of inserting an extending blade of a distal end portion of a rock fracture portion in a horizontal hole in which the center is rotated in a proper manner, cutting the rock bed so as to drop a rock bed divided into a lower portion of the tunnel by expanding an extending blade of the inserted tip portion, And collecting the rock mass with construction equipment and taking it out.
