[0022] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figures 1-5 shown, the present utility model provides a layered settlement instrument, including an outer tube 1. Two groups of limiting holes 4 are penetrated and opened on the inner wall of the outer tube 1. An inner tube 2 is arranged inside the outer tube 1. A plurality of moving seats 8 are slidably installed on the outer wall of the inner tube 2. Two limiting grooves 10 are opened on both outer sides of the plurality of moving seats 8. A first spring 11 is fixedly installed on the inner walls of the two limiting grooves 10. One end of the first spring 11 is fixedly installed with a limiting member 12. Two support plates 13 are fixedly installed on the tops of the plurality of moving seats 8. A threaded rod 14 is rotatably installed on the opposite sides of the two support plates 13. One end of the threaded rod 14 penetrates through the support plate 13 and is fixedly installed with a grip 16. Two sliding plates 17 are threadedly connected to the outer wall of the threaded rod 14. Clamping plates 18 are fixedly installed on the opposite sides of the two sliding plates 17. A limiting rod 15 is fixedly installed between the two support plates 13. The limiting rod 15 penetrates through the two sliding plates 17 and is slidably connected to the two sliding plates 17. A plurality of settlement rings 3 are slidably installed on the outer wall of the outer tube 1.

[0025] The overall effect achieved by the entire Embodiment 1 is that during use, according to the soil layer depth of the target area, the staff pulls the moving seat 8, and the moving seat 8 moves up and down along the inner tube 2 until it reaches a suitable position. Then the staff rotates the grip 16, and the threaded rod 14 rotates, thereby driving the two sliding plates 17 to approach each other. The clamping plate 18 contacts the inner tube 2, and the moving seat 8 is fixed. Then when the staff inserts the inner tube 2 into the outer tube 1, the inclined surface of the limiting member 12 contacts the inner wall of the outer tube 1 and is squeezed into the limiting groove 10. When the limiting member 12 moves beside the target limiting hole 4, the limiting member 12 passes through the limiting hole 4 under the elastic force of the first spring 11. Finally, the staff sets the settlement ring 3 on the outer wall of the outer tube 1 and moves it between the two limiting members 12. In this way, the position of the settlement ring 3 can be adjusted according to the soil layer depth in different places.

[0026] Embodiment 2, as Figures 1-5 shown, further, two storage grooves 19 are opened inside the outer tube 1. Electromagnets 20 are fixedly installed on the inner walls of the two storage grooves 19.

[0027] Further, a plurality of uniformly distributed fixing grooves 21 are formed in the inner walls of the two storage grooves 19. A plurality of uniformly distributed second springs 22 are fixedly installed at one end of the electromagnet 20 close to the storage groove 19. A baffle 23 is fixedly installed at one end of each of the plurality of second springs 22. The elastic force of the first spring 11 is greater than that of the second spring 22, and the force exerted by the settling ring 3 on the inclined surface of the limiting member 12 is not sufficient to overcome the elastic force of the first spring 11, preventing the limiting member 12 from being pushed into the limiting groove 10 by the settling ring 3 and the baffle 23.

[0028] Further, two fixing plates 6 are fixedly installed on the outer wall of the inner tube 2. A fixing rod 7 is fixedly installed between the two fixing plates 6. The fixing rod 7 passes through a plurality of moving seats 8 and is slidably connected to the moving seats 8 to prevent the moving seats 8 from rotating.

[0029] Further, two positioning holes 9 are formed through the inner walls of the plurality of moving seats 8. A plurality of uniformly distributed positioning grooves 5 are formed in the outer wall of the inner tube 2. When fixing the moving seat 8, the staff member pulls the moving seat 8 according to the soil layer depth until the two positioning holes 9 move beside the target positioning groove 5, which is convenient for the staff member to position.

[0030] Further, the outer walls of the plurality of baffles 23 are respectively in contact with the inner walls of the plurality of fixing grooves 21 to prevent the baffles 23 from tilting when moving.

[0031] Further, two sections of threads with opposite textures are provided on the threaded rod 14. The threaded rod 14 is respectively connected to the two sliding plates 17 through the two sections of threads with opposite textures.

[0032] The overall effect achieved by the entire Embodiment 2 is that when installing the inner tube 2, the staff member activates the electromagnet 20. The iron baffle 23 moves towards the electromagnet 20 under the attraction force and no longer blocks the limiting hole 4. The second spring 22 is compressed. When the limiting member 12 passes through the limiting hole 4, the staff member turns off the electromagnet 20. The baffle 23 moves under the elastic force of the second spring 22. Four of the baffles 23 are blocked by the limiting member 12, and the other baffles 23 cover the limiting holes 4 again to prevent the filler from entering the outer tube 1.

[0033] Working principle: When in use, according to the soil layer depth in the target area, the staff pulls the moving seat 8, and the moving seat 8 moves up and down along the inner tube 2 until it reaches a suitable position. Then the staff rotates the grip 16, the threaded rod 14 rotates, and further drives the two sliding plates 17 to approach each other. The clamping plate 18 contacts the inner tube 2, and the moving seat 8 is fixed. Then when the staff inserts the inner tube 2 into the outer tube 1, the inclined surface of the limiting member 12 contacts the inner wall of the outer tube 1 and is squeezed into the limiting groove 10. When the limiting member 12 moves beside the target limiting hole 4, the limiting member 12 passes through the limiting hole 4 under the elastic force of the first spring 11. Finally, the staff sets the settlement ring 3 on the outer wall of the outer tube 1 and moves it between the two limiting members 12. In this way, the position of the settlement ring 3 can be adjusted according to the soil layer depth in different places. Then the staff puts the outer tube 1 into the drill hole and fills the drill hole with filler. After filling, the staff rotates the inner tube 2, and the inclined surface of the limiting member 12 contacts the inner wall of the limiting hole 4 and enters the limiting groove 10. The settlement ring 3 will not be blocked on the outer tube 1 and can settle with the settlement of the soil body. When installing the inner tube 2, the staff activates the electromagnet 20, and the iron baffle 23 moves towards the electromagnet 20 under the attraction force, no longer blocking the limiting hole 4, and the second spring 22 is compressed. When the limiting member 12 passes through the limiting hole 4, the staff turns off the electromagnet 20, and the baffle 23 moves under the elastic force of the second spring 22. Four of the baffles 23 are blocked by the limiting member 12, and the other baffles 23 cover the limiting hole 4 again to prevent the filler from entering the inside of the outer tube 1.

[0034] The above is only the preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
