[0031] When the present invention is in use, the electrical equipment in the device is powered by an external power supply through a wire. The device controls the electrical equipment in the device by setting a control system. The method of installing the telescopic column 17 into the fixed column 1 is an existing mature technology, so it will not be described in detail. When the device is in use, as the bored pile continues to dig deeper, the inner wall of the bored pile will be like Fig.11 The concrete retaining wall 51 is installed on the inner wall of the bored pile in the manner shown. As the bored pile continues to dig deeper, the device adopts the following method: Fig.11 The installation method shown is mounted on the top of the concrete retaining wall 51. By adjusting the telescopic column 17, the device can be mounted on concrete retaining walls 51 of different sizes. When the device is not in use, the second rotating motor 22 drives the connecting rod 21 to rotate, so that the first fixed rod 24 rotates to be horizontal with the fixed column 1. When the device is in use, the fan 45 is started to blow air into the interior of the bored pile, thereby increasing the air circulation inside the bored pile. Reinforcing ribs are provided at the bottom of the second protective plate 3 and the fourth protective plate 13.

[0032] After the device is set up, the second rotating motor 22 drives the connecting rod 21 to rotate, so that the first fixing rod 24 rotates to Figure 1 In the state shown, the threaded rod 8 is driven to rotate by the first rotating motor 11, so that the sliding block 9 slides inside the first slot 7, thereby moving the first protective plate 2 to a preset position to protect the workers inside the bored pile; the movable design of the first protective plate 2 on the top of the fixed column 1 allows the first protective plate 2 to not only be adjusted in position according to different pile holes, thereby increasing the protective effect of the device on the workers, but also, during use, the device moves the first protective plate 2 to one end of the fixed column 1, which makes it convenient for the workers to maintain and overhaul the device, thereby increasing the ease of use of the device.

[0033] The third protective plate 12 and the fourth protective plate 13 in the device are optional parts. When the size of the bored pile does not reach the preset size, the third protective plate 12 and the fourth protective plate 13 are not installed. The fixing bolts installed in the first fixing hole 15 and the second fixing hole 16 can be taken out to complete the disassembly of the first protective plate 2, the second protective plate 3 and the third protective plate 12, the fourth protective plate 13. Conversely, the installation of the four can be completed; when the third protective plate 12, the fourth protective plate 13 are installed with the first protective plate 2, the second protective plate 3, the first positioning plate 43 and the second positioning plate 44 are not fixedly connected. When the third protective plate 12, the fourth protective plate 13 and the first protective plate 2, the second protective plate 3 are not installed, the first positioning plate 43 and the second positioning plate 44 are fixedly connected by bolts; Through this installation method, the first protective plate 2 and the second protective plate 3 can not only increase the protection effect for the workers through the double-layer design, but also the device is located on the upper layer of the bored pile, and when taking a break during the project, the second protective plate 3 is driven to rotate by the third rotating motor 46. After the second protective plate 3 rotates to the preset position, the second protective plate 3 is lowered to the preset position by the first electric extension rod 42 being retracted downward, so that the first protective plate 2 and the second protective plate 3 form a protective cover on the top of the bored pile. Through this operation method, protection can be formed above the bored pile when work is stopped to prevent people from falling into the bored pile, thereby increasing the safety of the device. When the third protective plate 12 and the fourth protective plate 13 are installed, the fourth protective plate 13 is driven to rotate by the fourth rotating motor 50 and the second electric extension rod 47 is used to lift and lower the device, so as to complete the operation of the device, thereby increasing the convenience of using the device.

[0034] During construction, the first fixing rod 24 is rotated to Figure 1 The first electric lifting rod 36 drives the first fixed rod 24 to move downward to the preset position, and the second electric slider 26 slides in the second slide groove 25 to make the movable rod 27 rotate to a position away from the first protective plate 2. Move to a preset position on the first fixed rod 24, and then adjust the position of the clamping plate 33 by sliding the third electric slider 32 in the third slide groove 31, so that the two clamping plates 33 are adjusted to a state where they can abut against the outside of the lifting bucket. Then, when the lifting bucket is lifted upward to the preset height, the clamping plates 33 abut and clamp against the outside of the lifting bucket, and the second fixed rod 30 maintains a rising speed synchronized with the lifting bucket so that the clamping plates 33 are always in a state of abutting and clamping the lifting bucket. Through this operation method, it can play a stabilizing auxiliary role when the lifting bucket rises to a preset height position, increase the stability of the lifting bucket when it is lifted upward, and prevent the lifting bucket from shaking when it is lifted to a high place, and the soil debris inside the lifting bucket from falling, affecting the safety of the staff.

[0035] During the construction of the bored pile, the workers do not enter the interior of the bored pile. Then the first fixed rod 24 is adjusted to a downward vertical state, and the rotating rod 28 is adjusted to a horizontal state. At this time, the second fixed rod 30 is driven to rotate by the second rotating motor 39, so that the arc plate 34 is rotated to the side facing the inner wall of the bored pile. Then, through the movement of the connecting rod 21 on the second auxiliary rod 18, combined with the third rotating motor 35 to drive the connecting plate 23 to rotate and the second electric lifting rod 38 to drive the rotating rod 28 to extend, the arc plate 34 can squeeze the inner wall of the bored pile. Through this operation, the soil on the inner wall of the upper section of the bored pile can be compacted, which is convenient for the workers to install the concrete retaining wall 51 later.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
