[0015] The following will be further described in detail through specific embodiments:

[0016] The reference numerals in the accompanying drawings of the instruction manual include: support column 1, telescopic column 2, upright column 3, protective plate 4, telescopic plate 5, sliding column 6, connecting rod 7, sliding block 8, base plate 9, and pulley 10.

[0017] The basic implementation examples are as follows: Figs. 1-2 As shown: A safety protection device for the borehole opening of a bored pile includes four columns 3, which form a square. Each of the four columns 3 is hinged to a pulley 10 at its bottom. A telescopic column 2 is provided between two adjacent columns 3. Support columns 1 are sleeved at both ends of the telescopic column 2. The support columns 1 and the telescopic columns 2 are slidably connected. The end of the support column 1 away from the telescopic column 2 is fixedly connected to the side wall of the column 3. The support columns 1 and the telescopic columns 2 form a square and are parallel to the ground.

[0018] Each of the four telescopic columns 2 is equipped with a telescopic plate 5. Both ends of the telescopic plate 5 are fitted with protective plates 4. The protective plates 4 are “∟” shaped. The right-angled ends of the outer side of the protective plates 4 are fixedly connected to the column 3. The ends of two adjacent telescopic plates 5 are slidably connected to the same protective plate 4. The four protective plates 4 can form a square. The right-angled ends of the outer side of the four protective plates 4 are fixedly connected to the adjacent column 3. The inner side of the support column 1 extends to the bottom of the protective plate 4 and is fixedly connected to it. A driving mechanism is provided at the center of the four protective plates 4. The driving mechanism includes a sliding column 6 and a sliding block 8. The sliding column 6 is fixedly connected to the center of the device. A base plate 9 is fixedly connected to the lower part of the sliding column 6. The sliding block 8 is slidably connected to the sliding column 6. Two connecting rods 7 are provided between the sliding block 8 and the protective plate 4. One end of the connecting rod 7 is hinged to the sliding block 8, and the other end is hinged to the inner wall of the protective plate 4. A linear motor is fixedly connected to the sliding block 8.

[0019] The protective plate 4 and the telescopic plate 5 are made of steel plates or steel bars welded into a frame.

[0020] The specific implementation process is as follows: When in use, start the linear motor, drive the sliding block 8 to rise along the sliding column 6, drive the connecting rod 7 to deflect, so that the other end of the connecting rod 7 drives the protective plate 4 to move closer to the sliding column 6. At this time, the protective plate 4 and the sleeved telescopic plate 5 slide relative to each other, so that the telescopic plate 5 slides into the interior of the protective plate 4, and drives the column 3 and the support column 1 to shift, so that the telescopic column 2 slides into the support column 1, while the column 3 moves closer to the center under the drive of the pulley 10, completing the shrinking operation, reducing the distance between the protective plates 4, so that the size of the square enclosed by the protective device is slightly larger than the diameter of the pile hole to be blocked, and vice versa, the square enclosed by the protective plates 4 can be enlarged.
