[0031] When drilling a hole on a water-sensitive soft rock slope, the drilling depth should be below the potential sliding surface of the slope. After the drilling is completed, the pile body 1 is placed in the drilled hole, and then the traction rope 2 11 is pulled to move the sliding sleeve 6 connected to the traction rope 2 11 upward.

In addition, when the sliding sleeve 6 connected to the traction rope 2 11 moves upward, under the action of the traction rope 1 10, the sliding sleeve 6 at the bottom moves downward, so that the connecting rod 2 5 in the limiting structure at the bottom drives the connecting rod 1 4 to rotate around the hinge seat 3, and the angle between the connecting rod 2 5 and the connecting rod 1 4 decreases, and the connecting rod 2 5 and the connecting rod 1 4 are in an outward expansion state. During the movement of the sliding sleeve 6, when the sliding sleeve 6 contacts the wedge-shaped locking block 12, the wedge-shaped locking block 12 is pressed into the limiting sliding groove 13 under the action of the sliding sleeve 6. When the sliding sleeve 6 is no longer in contact with the wedge-shaped locking block 12, the wedge-shaped locking block 12 pops out again under the action of the spring 14, so that the wedge-shaped locking block 12 limits the sliding sleeve 6, so that the connecting rod 2 5 and the connecting rod 1 4 are always in an outwardly extended state. Then pour mortar into the drilled hole.
