Description

Technical Field

[0001] This utility model relates to the field of positioning and anti-deviation devices, and in particular to a pile foundation positioning and anti-deviation device for pile foundation engineering. Background Technology

[0002] As one of the core technologies in the modern construction field, pile foundation engineering undertakes the important task of improving the bearing capacity and stability of building foundations. At present, pile foundation construction generally adopts various pile types such as bored piles and precast piles to adapt to different geological conditions and engineering needs. However, in the actual construction process, the positioning accuracy and verticality control of pile foundations are still one of the technical difficulties.

[0003] Existing pile foundation positioning and anti-deviation devices for pile foundation engineering typically employ methods such as the jacking method and static pressure pile supplementation. The jacking method applies horizontal thrust to reset the pile column, which is suitable for pile columns with a small degree of deviation. The static pressure pile supplementation method compensates for the bearing capacity loss caused by deviation by adding additional pile foundations, which is suitable for occasions with a large degree of deviation or where it is necessary to increase the bearing capacity.

[0004] On the one hand, existing pile foundation positioning and anti-deviation devices typically use multi-directional, multi-layer steel pipes to maintain the stability of the grouting sleeve. The labor cost of installation is relatively high, and it is impossible to quickly clamp grouting sleeves of different diameters and keep the sleeve vertically stable during descent. On the other hand, existing pile foundation positioning and anti-deviation devices require additional steel plates to be laid around the device to prevent it from sinking in muddy areas. It is impossible to reduce the number of steel plates used and the cost by manually extending the stress points of the device. Therefore, a pile foundation positioning and anti-deviation device for pile foundation engineering is proposed to solve the above problems. Utility Model Content

[0032] Reference Figures 1-3 This utility model provides an embodiment of a pile foundation positioning and anti-deviation device for pile foundation engineering, including a positioning base 1. The positioning base 1 is used to conform to the soil surface or be suspended above the top surface of the pile foundation to increase the stability of the device. A level bubble can be set to adjust the horizontal stability of the positioning base 1. A fixing frame 2 is fixedly connected to the top of the outer wall of the positioning base 1. The fixing frame 2 is used to fix two sets of sliding rods 3 to keep the positioning base 1 horizontal. There are two sets of fixing frames 2. Sliding rods 3 are fixedly connected between the two sets of fixing frames 2. The sliding rods 3 are used to keep the sliders 4 moving stably. Sliding blocks 4 are slidably connected to the outer wall of the sliding rods 3. There are four sliders 4 in total, two sets on each side, to improve the clamping stability of the positioning plate 5. There are two sets of sliders 4.

A connecting rod 7 is hinged to the middle of the outer wall of the connecting rod 6. When the connecting rod 7 drives the turntable 8 to rotate through the limiting component, it drives the connecting rod 7 to make a fan-shaped unfolding motion along the hinge of the connecting rod 6, so that the turntable 8 rotates and drives the connecting rod 6 to move accordingly. The turntable 8 is hinged to the end of the outer wall of the connecting rod 7. The turntable 8 is used to change the rotation angle through the limiting component, so that the connecting rod 7 drives the connecting rod 6 to move inward. The outer wall of the turntable 8 is connected to the limiting plate 9 through the limiting component. The limiting plate 9 is used to provide the center point for the opposing clamping of the positioning plate 5, so that the grouting sleeve is kept in the center position. The outer wall of the turntable 8 is slidably connected to the back of the outer wall of the limiting plate 9. The bottom of the outer wall of the limiting plate 9 is fixedly connected to the top of the outer wall of the positioning base 1.

[0033] Reference Figures 2-4An extension plate 10 is rotatably connected to the inner wall of the side of the positioning base 1. Four sets of extension plates 10 are provided to increase the support position and support points of the positioning base 1, preventing it from sinking into the soil. An auxiliary groove 11 is provided on the inner wall of the end of the extension plate 10. The auxiliary groove 11 is used to engage with an auxiliary block 14 to maintain the stable up-and-down movement of the fixing rod 13. A fixing rod 13 is elastically connected to the inner wall of the end of the extension plate 10 via a return spring 12. The fixing rod 13 is used for external manual release of the limit, facilitating manual unfolding of the extension plate 10. An auxiliary block 14 is fixedly connected to the bottom of the outer wall of the fixing rod 13. The auxiliary block 14 engages with the auxiliary groove 11 to maintain the stable movement of the fixing rod 13, while allowing the extension plate 10 to rotate with the fixing rod 13. A fixing block 15 is fixedly connected to the middle of the outer wall of the fixing rod 13. The fixing block 15 engages with a fixing groove 16 to fix the angle of the fixing rod 13. The top of the outer wall of the positioning base 1 is provided with a fixing groove 16. The fixing groove 16 is provided with two sets of right angles for locking the fixing block 15 to fix the extension plate 10 when it is unfolded and stored. The number can be changed according to actual needs to achieve the effect of fixing the extension plate 10 at multiple angles. One end of the return spring 12 is fixedly connected to the bottom of the inner wall of the end of the extension plate 10, and the other end of the return spring 12 is fixedly connected to the bottom of the outer wall of the fixing rod 13. Through the opposing pressing force between the return spring 12 and the extension plate 10, the fixing block 15 is always locked on the inner wall of the fixing groove 16 without being affected by external force. The outer wall of the fixing rod 13 is slidably connected to the inner wall of the end of the extension plate 10 and the top inner wall of the positioning base 1. The outer wall of the auxiliary block 14 is slidably connected to the inner wall of the auxiliary groove 11, and the outer wall of the fixing block 15 is locked on the inner wall of the fixing groove 16.

[0034] Reference Figures 3-5The limiting component includes a rotating shaft 17, which provides a support point and rotation origin for the turntable 8. The bottom end of the outer wall of the rotating shaft 17 is fixedly connected to the center of the outer wall of the turntable 8. A directional block 18 is fixedly connected to the outer wall of the rotating shaft 17, which engages with the directional groove 21 to keep the limiting frame 20 moving stably. The top end of the outer wall of the rotating shaft 17 is elastically connected to the limiting frame 20 via a limiting spring 19. The limiting frame 20 is used to release the limiting from the outside. A handle is provided on the outer wall for easy manual rotation. The inner wall of the limiting frame 20 has a directional groove 21, which engages with the directional block 18 to keep the limiting frame 20 moving stably while allowing the rotating shaft 17 to rotate with the limiting frame 20. A limiting block 22 is fixedly connected to the bottom end of the outer wall of the limiting frame 20, which engages with the limiting groove 23 to fix the turntable. The rotation angle of 8 is such that a limiting groove 23 is opened at the top of the outer wall of the limiting plate 9. Several sets of limiting grooves 23 are provided for multiple locking of the limiting block 22 to fix the clamping distance of the positioning plate 5. One end of the limiting spring 19 is fixedly connected to the top of the outer wall of the rotating shaft 17, and the other end of the limiting spring 19 is fixedly connected to the top of the inner wall of the limiting frame 20. Through the opposing extrusion force between the limiting spring 19 and the rotating shaft 17, the limiting block 22 is always locked on the inner wall of the limiting groove 23 without being affected by external force. The outer wall of the rotating shaft 17 passes through and is slidably connected to the inner wall of the limiting plate 9. The outer wall of the directional block 18 is slidably connected to the inner wall of the directional groove 21. The inner wall of the limiting frame 20 is slidably connected to the outer wall of the rotating shaft 17. The end of the outer wall of the limiting block 22 is locked on the inner wall of the limiting groove 23.

[0035] Working principle: When the pile sleeve is kept stable and descending vertically, the limiting frame 20 is manually pulled to move the limiting block 22 out of the limiting groove 23 to release the limitation. Then, the limiting frame 20 is rotated to drive the rotating shaft 17 to rotate. The rotating shaft 17 drives the turntable 8 to rotate. The turntable 8 then drives the connecting rod 7 to make a fan-shaped unfolding motion along the hinge of the connecting rod 6, so that the connecting rod 6 moves laterally with the rotation angle of the turntable 8. The connecting rod 6 drives the slider 4 to move inward along the sliding rod 3. Then, the slider 4 drives the positioning plate 5 to contact the pile sleeve, and then pushes the limiting frame 20 inward to make the limiting block 22 spring back into the corresponding limiting groove 23, so that the pile sleeve keeps vertically downward and achieves the effect of preventing pile foundation positioning deviation.

[0036] When positioning the pile foundation on muddy ground, the fixing block 15 is disengaged from the fixing groove 16 by manually pulling the fixing rod 13 to release the limit. Then, the fixing rod 13 is rotated to extend the extension plate 10 outward. Then the fixing rod 13 is released, and the fixing block 15 is snapped back into the fixing groove 16 by the return spring 12. This increases the support area of ​​the positioning base 1 and prevents the positioning base 1 from sinking into the mud and causing damage.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
