In operation, in the initial state, the driving sleeve 23 slides along the guide rail 11 under the action of its own gravity and only the bottom end of the inclined surface of the main frame 1. The clutch controller 26 is located at the rear side of the tightening pin 231, then the driving motor 3 is started, and since the tightening pin 231 and the hollow drill rod 24 are in a disengaged state at the time, the hollow drill rod 24 does not rotate along with the rotation of the driving sleeve 23, and the hollow drill rod 24 is extended forwards under the action of the threaded matching relationship between the driving sleeve 23 and the hollow drill rod 24 until the drill bit 25 at the front end of the hollow drill rod 24 contacts the ground. At this time, the hollow drill rod 24 will not extend forward under the action of the ground, but the driving sleeve 23 still continues to rotate under the driving action of the driving motor 3, so that the driving sleeve 23 will move upward along the hollow drill rod 24 until the driving sleeve 23 moves to the top end of the inclined plane of the main frame body 1, and in the process, the operator needs to push the clutch controller 26 to move upward together, and in the moving process, it is ensured that the clutch controller 26 is always located behind the tightening pin 231. After the driving sleeve 23 moves to the top end of the inclined surface of the main frame 1, the clutch controller 26 is pushed downwards until the tightening pin 231 is tightened on the hollow drill rod 24 under the action of the tapered surface of the wedge ring 262, at this time, the hollow drill rod 24 and the driving sleeve 23 are relatively fixed to form a rigid whole, so that the hollow drill rod 24 rotates along with the rotation of the driving sleeve 23, and the drill 25 performs a drilling function on the ground. As the drilling process continues, the hollow drill rod 24 and the driving sleeve 23 move forward together as a unit until they reach the bottom end of the inclined surface of the main frame body 1, i.e., the state shown in fig. 19. Then, the clutch controller 26 is released, and the tightening pin 231 is disengaged from the hollow drill rod 24 by the spring 232, i.e., the state shown in fig. 20. At this time, the rotation of the hollow drill rod 24 is stopped, and the driving sleeve 23 is still rotated by the driving motor 3, so that the driving sleeve 23 is moved upward along the hollow drill rod 24 again until the driving sleeve 23 is moved to the top end of the inclined surface of the main frame 1, i.e. the state shown in fig. 21. The above steps are repeated in a circulating way until the requirement of the excavation depth of the motor road junction is reached.
