[0022] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0023] A device for detecting the thickness of sediment in foundation construction, referring to... Figure 1 - Figure 5 The system includes a support platform 1. Three sets of adjusting columns 2 are installed in a circular array at equal intervals on the outside of the support platform 1. Expansion joints 3 are installed on the outer ring surface of the adjusting columns 2. A sliding groove 301 is opened on one side of the outer side of the expansion joint 3. A threaded rod 4 is installed on the outer side of the adjusting column 2 and inside the sliding groove 301. An adjusting nut 5 is installed on the outer ring surface of the threaded rod 4. A spherical block 6 is installed at the bottom of the expansion joint 3. A support block 7 is installed on the outside of the spherical block 6. A support plate 8 is installed at the bottom of the support block 7. A base 9 is installed at one end of the top of the support platform 1. A bubble level 10 is installed at one end of the top of the base 9. A protective cover 11 is installed on the top of the base 9 and outside the bubble level 10.

[0024] Reference Figure 1 - Figure 3The top end of the three sets of adjusting columns 2 is rotatably connected to the outside of the support platform 1, and the outer side of the adjusting column 2 is slidably connected to the inside of the telescopic joint 3, which facilitates the adjustment and expansion of the adjusting column 2, making the bottom support plate 8 more stable after contacting the ground. The slidable connection between the outer side of the adjusting column 2 and the inside of the telescopic joint 3 facilitates the height adjustment of the device, thereby enabling installation on uneven ground and ensuring the flatness of the support platform 1. The support platform 1 can be leveled. By rotating the adjusting nut 5 on the outside of the threaded rod 4, the telescopic joint 3 can be squeezed, thereby fixing the telescopic joint 3 to the outside of the adjusting column 2.

[0025] Reference Figure 1 - Figure 2 The outer side of the spherical block 6 is rotatably connected to the inner side of the support block 7. The spherical block 6 is movably installed inside the support block 7. The rotation of the spherical block 6 inside the support block 7 ensures that the support plate 8 can tilt synchronously and contact the ground when the ground tilts. Fixed cones 12 are symmetrically installed at both ends of the top of the support plate 8. One end of the bottom of the fixed cone 12 extends through the support plate 8 and below its bottom. The outer ring surface of the fixed cone 12 is threadedly connected to the inner side of the support plate 8. A handle 13 is installed on the top of the fixed cone 12. By rotating the handle 13, the fixed cone 12 is driven to rotate and descend into the soil. Two sets of fixed cones 12 are set on each support plate 8 to make the device more stable.

[0026] Reference Figure 1 and Figure 4 A vertical plate 14 is symmetrically installed on the top of the support platform 1. A guide wheel 15 is placed between the outer sides of the vertical plate 14. A traction rope 16 is installed on the guide wheel 15. One end of the traction rope 16 passes through the support platform 1 and a test needle 17 is installed thereon. The end of the traction rope 16 away from the test needle 17 is connected to an external traction device. By pulling the traction device, the test needle 17 can be accurately and stably inserted into the pile hole. Finally, the test needle 17 will transmit the test result to the external operating instrument on the ground.

[0027] Reference Figure 5 The base 9 has two symmetrical T-shaped grooves 901 on its two longer edges at the top. T-shaped sliders 18 are installed at both ends of the bottom of the protective cover 11 and inside the two T-shaped grooves 901. The outer side of the T-shaped sliders 18 is slidably connected to the inner sidewall of the T-shaped grooves 901, so that the protective cover 11 can slide freely along the T-shaped grooves 901. This allows the user to adjust the position of the protective cover 11 as needed. When not in use, the protective cover 11 can be slid to the outside of the bubble level 10 to protect it and prevent damage to the bubble level 10.

[0028] Reference Figure 5A protrusion 19 is installed on one end of the bubble level 10. A telescopic rod 20 is installed on the outside of the protrusion 19. A return spring 21 is installed on the outer ring surface of the telescopic rod 20. A connecting plate 22 is installed on the end of the telescopic rod 20 away from the protrusion 19. A positioning rod 23 is installed on the outer end of the connecting plate 22 away from the telescopic rod 20. A positioning hole 1101 is opened on one end of the protective cover 11. The inner wall size of the positioning hole 1101 is adapted to the outer ring size of the positioning rod 23. The telescopic rod 20 is extended and retracted by pulling the connecting plate 22. The return spring 21 provides a restoring force to ensure that the telescopic rod 20 can return to the initial position. The positioning rod 23 is installed on the outer end of the connecting plate 22 away from the telescopic rod 20. It is used to cooperate with the positioning hole 1101 on the protective cover 11 to fix the protective cover 11 on the outside of the bubble level 10 and prevent the protective cover 11 from sliding on its own.

[0029] The implementation principle of the device for detecting the thickness of sediment in foundation construction according to an embodiment of this application is as follows: When using the device, the top end of the three sets of adjusting columns 2 is rotatably connected to the outside of the support platform 1, and the outer side of the adjusting column 2 is slidably connected to the inside of the expansion joint 3, which facilitates the adjustment and expansion of the adjusting column 2, making the bottom support plate 8 more stable after contacting the ground. The slidable connection between the outer side of the adjusting column 2 and the inside of the expansion joint 3 facilitates the height adjustment of the device, thereby enabling installation on uneven ground and ensuring the flatness of the support platform 1. The support platform 1 can be leveled. The expansion joint 3 can be squeezed and fixed by rotating the adjusting nut 5 outside the threaded rod 4. The flatness of the support platform 1 can be observed by the bubble level 10. The spherical block 6 rotates inside the support block 7 to ensure that the support plate 8 can tilt and contact the ground synchronously when the ground is tilted. The fixed cone 12 is driven to rotate and descend into the soil by rotating the handle 13. Two sets of fixed cones 12 are set on each support plate 8 to make the device more stable. The end of the traction rope 16 away from the test needle 17 is connected to the outside. The traction device is connected to the traction rope 16. The end of the traction rope 16 away from the test needle 17 is connected to the external traction device. By pulling the traction device, the test needle 17 can be accurately and stably inserted into the pile hole. Finally, the test needle 17 will transmit the test result to the external operating instrument on the ground. The protective cover 11 can slide freely along the T-shaped slide groove 901, allowing the user to adjust the position of the protective cover 11 as needed. When not in use, the protective cover 11 can be slid outside the bubble level 10 to protect it and prevent damage to the bubble level 10. The connecting plate 22 enables the telescopic rod 20 to extend and retract, and the return spring 21 provides restoring force to ensure that the telescopic rod 20 can return to its initial position. A positioning rod 23 is installed on the outer end of the connecting plate 22 away from the telescopic rod 20. It is used to cooperate with the positioning hole 1101 on the protective cover 11 to fix the protective cover 11 to the outside of the bubble level 10, so as to prevent the protective cover 11 from sliding on its own and making the operation convenient. The external helix opening angle of the threaded rod 4 is 20 degrees, and the thread self-locking condition is calculated by the following formula: self-locking condition = friction coefficient * tan (helix angle) ≥ 1.
