[0026] Example 2:

[0027] On the basis of embodiment 1, the present invention is as follows Figure 1 、 Figure 2 、 Figure 3 and Figure 5As shown, it is disclosed that the middle end of the accommodating hole 2 is fixedly connected with a fixing column 13, the middle end of the anti-pullout pin rod 9 is provided with a guide groove 14, the surface of the fixing column 13 is movably connected to the surface of the guide groove 14, and the four sides of the top of the pile body 1 are fixedly connected with positioning columns 19, the surface of the pile cap 3 is movably connected to the surface of the positioning columns 19, the top of the positioning columns 19 is threadedly connected with a fixing bolt 4, and the top of the pile cap 3 is movably connected to the upper end of the fixing bolt 4. The number of accommodating holes 2, rotating plates 10 and anti-pullout pin rods 9 are all eight.

[0028] In this technical solution, the purpose of guiding the anti-pullout pin rod 9 is achieved by setting the fixing column 13 and the guide groove 14, thereby preventing the anti-pullout pin rod 9 from being offset during the movement. The purpose of positioning and installing the pile cap 3 and the pile body 1 is achieved by setting the positioning column 19 and the fixing bolt 4.

[0029] Example 3:

[0030] On the basis of embodiment 1, the present invention is as follows Figure 1 、 Figure 2 and Figure 4 As shown, it is disclosed that a warning light 6 is fixedly installed on the left end of the top of the pile cap 3, a magnetic plate 12 is fixedly connected to the upper end of the front surface of the rotating shaft 11, and a support plate 8 is movably connected to the upper end of the rotating shaft 11 and below the magnetic plate 12 through a bearing. The left side of the support plate 8 is fixedly connected to the upper end of the left side of the inner cavity of the pile body 1, and the left end of the top of the support plate 8 is fixedly connected to the fixed box 7. The right side of the fixed box 7 is movably connected to the movable frame 20, and a magnetic control switch 15 is fixedly installed on the middle end of the right side of the movable frame 20. Both ends of the right side of the movable frame 20 are movably connected to the ball bearing 16, and the right side of the ball bearing 16 is movably connected to the surface of the rotating shaft 11. Both ends of the left side of the movable frame 20 are movably connected to the guide slide bar 17, and the left side of the guide slide bar 17 is fixedly connected to the left side of the inner cavity of the fixed box 7. The middle end of the left side of the movable frame 20 is fixedly connected to the support spring 18, and the left side of the support spring 18 is fixedly connected to the middle end of the left side of the inner cavity of the fixed box 7.

[0031] In the present technical solution, the purpose of supporting the upper end of the rotating shaft 11 is achieved by setting the support plate 8, so as to prevent the rotating shaft 11 from tilting due to the rotation force. The setting of the ball 16 can support it between the movable frame 20 and the rotating shaft 11, effectively preventing the magnetic switch 15 from contacting the surface of the rotating shaft 11 and causing wear. By setting the prompt light 6, the magnetic plate 12, the fixed box 7, the movable frame 20 and the magnetic switch 15, when the rotating shaft 11 and the rotating plate 10 rotate and drive the anti-pull pin rod 9 to extend outside the pile body 1, the magnetic plate 12 can be driven to rotate until the center lines of the rotating shaft 11, the rotating plate 10 and the anti-pull pin rod 9 can coincide under the action of rotation, so that the magnetic plate 12 can be in the magnetic control position under the action of rotation. The right side of the switch 15, and under the action of the magnetic force of the magnetic plate 12, the contacts inside the magnetic control switch 15 are closed, and the circuit of the warning light 6 is connected and lights up, so that the personnel can be effectively prompted to stop operating the static drive 5 to work, so as to avoid the personnel continuing to operate the static drive 5 to cause the rotating shaft 11 and the rotating plate 10 to rotate, and cause the anti-pullout pin rod 9 to retreat to the inside of the pile body 1, which brings great convenience to the personnel's use and operation. Through the setting of the guide slide bar 17, the purpose of guiding the left end of the movable frame 20 is achieved, and the movable frame 20 is prevented from tilting during the movement. Through the setting of the support spring 18, a thrust can be generated on the movable frame 20 during use, so that the ball 16 can maintain contact with the rotating shaft 11.

[0032] The working principle of the present invention is as follows: in combination with the design of the pile foundation of the building, the site is leveled and the positioning and laying out are carried out, and the pile body 1 is implanted by static pressure according to the positioning. When the pile body 1 reaches the designed elevation, the pile pressure is stopped, and then the static driver 5 controls the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 can drive the rotating plate 10 to rotate. While the rotating plate 10 rotates, it can push the anti-pullout pin rod 9 to move through the hinge, so that the anti-pullout pin rod 9 can extend to the outside of the pile body 1 through the accommodating hole 2, and the anti-pullout pin rod 9 can be inserted into the soil foundation around the pile body 1, until the rotating shaft 11 causes the center lines of the rotating plate 10 and the anti-pullout pin rod 9 to coincide with each other under the action of the rotation. At this time, the depth of the anti-pullout pin rod 9 inserted into the soil foundation reaches the maximum, so that the anti-pullout pin rod 9 can be effectively reinforced between the pile body 1 and the soil foundation, greatly improving the anti-pullout performance and bearing strength of the pile body 1 during use, and because the overall construction method is simple, the construction period is greatly shortened, and the efficiency of the construction operation is improved.
