Description
Technical Field
[0001] The invention relates to the technical field of pile foundations, and in particular to a pile foundation with a shock-absorbing function. Background Art
[0002] The pile foundation is also called the pile foundation, which is composed of the pile and the cap connected to the top of the pile. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Building pile foundations are usually low cap pile foundations.
[0003] At present, when the foundation piles are sunk, the foundation piles are hoisted into the foundation pit by a crane. After the foundation piles are hoisted in, the staff are required to straighten the foundation piles to prevent the foundation piles from tilting due to the uneven bottom of the foundation pit, which affects their use. This not only reduces the overall work efficiency, but also the foundation piles have a certain weight, which makes it troublesome for the staff to adjust the foundation piles. Moreover, when the foundation piles are placed in the foundation pit, they are easily hit in the foundation pit due to their own weight, causing damage to the foundation piles. For this reason, we propose a foundation pile with a shock-absorbing function. Summary of the invention

[0022] A through hole is formed on the surface of the sleeve 31 for the anchor rod 34 to pass through. When the sleeve 31 rotates, the sleeve 31 can contact the anchor rod 34 through the inner side of the through hole on the surface, so that the anchor rod 34 is vertical compared to the foundation pile 1.
[0023] The auxiliary member 35 includes a resisting rod 351, which penetrates the anchor rod 34 and is slidably connected to the anchor rod 34. A pull rod 352 is fixed to the side of the resisting rod 351 away from the slider 32. A spring 353 is fixed to the end of the pull rod 352 away from the resisting rod 351. The end of the spring 353 away from the pull rod 352 is fixed to the inner wall of the anchor rod 34. A support rod 354 is hinged on the surface of the pull rod 352. The end of the support rod 354 away from the pull rod 352 is hinged to the insertion rod 355.
