[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-7 This utility model provides a technical solution: A rotary drilling and grouting pile construction device includes a workbench 1 with a circular opening 8 at the top. Mounting plates 2 are fixedly installed on the top of the workbench 1 on both sides of the circular opening 8. Drive components 3 are installed on the side walls of the two sets of mounting plates 2. Driving components 3 are respectively equipped with a sludge suction pipe 4 and a water pipe 7. The other end of the sludge suction pipe 4 and the water pipe 7 are connected to a corresponding extraction device. The drive components 3 are connected to a linkage component 5. A connecting pipe 12 is fixedly connected to one end of the sludge suction pipe 4 and the water pipe 7. A rectangular cover 15 is fixedly installed on the outer wall of the connecting pipe 12. Telescopic components 10 are installed on the outer walls of the rectangular cover 15 on both sides. The telescopic components 10 are connected to a sliding component 16. A rotating component 17 is installed between the outer wall of the connecting pipe 12 and the inner wall of the rectangular cover 15. The rotating component 17 is connected to a mixing component 14. A steel cable 6 is fixedly installed on the top of the rectangular cover 15. The other end of the steel cable 6 is connected to a retraction device.

[0021] Furthermore, the drive assembly 3 includes a motor 33, which is fixed to the side wall of a set of mounting plates 2. The output end of the motor 33 extends through to the rear side of the mounting plate 2, and a take-up roller 31 is fixedly installed at the output end of the motor 33. A take-up roller 32 is rotatably connected to the rear side of another set of mounting plates 2. A linkage assembly 5 is installed between the rear sides of the take-up roller 31 and the take-up roller 32. The inside of the take-up roller 31 and the take-up roller 32 are respectively wound and connected to the sewage suction pipe 4 and the water pipe 7. When the output end of the motor 33 drives the take-up roller 31 to rotate, the linkage assembly 5 will drive the take-up roller 32 to rotate as well, so that the sewage suction pipe 4 and the water pipe 7 can be retracted and extended at the same time.

[0022] Furthermore, the linkage component 5 includes a pulley 51, which is fixedly installed on the outer rear side of the take-up roller 32. The pulley 52 is also fixedly installed on the outer rear side of the take-up roller 31. A belt 53 is installed between the pulley 51 and the pulley 52. ​​The motor 33 drives the take-up roller 31 to rotate, and the pulley 52 rotates through the belt 53.

[0023] Furthermore, flanges 11 are fixedly installed at the top of the connecting pipe 12 and the bottom of the suction pipe 4. Several sets of bolts and fasteners are installed between the two sets of flanges 11. Loosening the bolts and fasteners makes it easy to disassemble the suction pipe 4 and the connecting pipe 12.

[0024] Furthermore, the telescopic component 10 includes a circular tube 102. Two sets of circular tubes 102 are respectively fixed to the outer walls of the left and right sides of the rectangular cover 15. A circular rod 101 is inserted into the inner wall of the opening at the other end of the two sets of circular tubes 102. The other end of the circular rod 101 is connected to the sliding component 16. A bolt 103 passes through the outer wall of the outlet of the circular tube 102 and is threadedly connected to the circular tube 102. The circular rod 101 is slid on the inner wall of the circular tube 102 so that the sliding component 16 is in contact with the inner wall of the injection hole. Then the bolt 103 is tightened so that the bottom of the bolt is in contact with the bottom of the circular rod 101.

[0025] Furthermore, the sliding assembly 16 includes a mounting bracket 161, which is fixedly connected to the other end of the round rod 101, and a guide wheel 162 is rotatably connected to the inner wall of the mounting bracket 161.

[0026] The guide wheel 162 is slidably connected to the inner wall of the injection hole, thereby ensuring that the rectangular cover 15 avoids shaking when moving inside the injection hole and always remains stable.

[0027] Furthermore, the rotating assembly 17 includes a second motor 171, which is fixed to the top of the rectangular cover 15. A gear 172 is fixedly installed at the output end of the second motor 171. A gear ring 173 is rotatably connected to the lower outer wall of the connecting pipe 12. The gear 172 and the gear ring 173 are meshed and connected. The bottom of the gear ring 173 is connected to the stirring assembly 14.

[0028] The output end of motor 171 drives gear 172 to rotate, which in turn drives the mixing assembly 14 to rotate through the gear ring 173, thus breaking up the soil at the bottom of the injection hole.

[0029] Furthermore, the mixing assembly 14 includes mixing rods 142, and several sets of mixing rods 142 are evenly fixed at the bottom of the toothed ring 173. Each set of mixing rods 142 has a mixing blade 141 fixedly installed on the lower outer wall. While the toothed ring 173 rotates, the mixing rods 142 will continuously mix the soil and water through the mixing blades 141 to form a mixed slurry, which is convenient for the sewage suction pipe 4 to extract.

[0030] Furthermore, a filter sleeve 13 is fixedly installed at the bottom of the connecting pipe 12. The filter sleeve 13 is used to prevent stones in the mud from entering the suction pipe 4.

[0031] Furthermore, a control device 9 is fixedly installed on the side wall of the workbench 1. The control device 9 is electrically connected to the motor 171. The control device 9 is a PLC controller used to control the operation of the motor 171.

[0032] Working principle: First, the sliding component 16 is brought into contact with the inner wall of the grouting hole by the telescopic component 10. Then, the rectangular cover 15 is sent into the grouting hole through the circular opening 8 by the external extension device via the steel cable 6. Then, the drive component 3 extends the sewage suction pipe 4 continuously. At the same time, the linkage component 5 drives the other drive component 3 to extend the water pipe 7 as well. When the rectangular cover 15 is lowered to the bottom of the grouting pile, the water pipe 7 injects water into the bottom of the grouting pile. Then, the rotating component 17 drives the mixing component 14 to mix the soil and water until mud is formed. Then, the sewage suction pipe 4 pumps the mud to the outside of the grouting pile.
