[0002] A deep foundation (see figure) consisting of a pile and a pile cap connected to the top of the pile (referred to as the cap) or a single pile foundation connected by a column and a pile foundation is referred to as a pile foundation. 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. Pile foundations are widely used in high-rise buildings.

[0003] A Chinese patent discloses a pile foundation (authorization announcement number CN218346231U), which includes: a hollow pile body, with openings on both sides of the pile body; wings arranged in the openings, the shape of the wings matches the shape of the openings, and the bottom edge of the wings is hinged to the bottom edge of the openings through hinges, and protruding struts are arranged on the surfaces of the two wings facing each other; and a pile driving head arranged in the inner cavity of the pile body and located above the two struts, when the pile driving head moves downward, the pile driving head can squeeze the struts outward to make the two wings unfold outward. After the pile foundation is driven into the soil layer, the wings on both sides of the pile body are unfolded and embedded in the soil layer, which increases the resistance when the pile body is pulled up, thereby increasing the pull-out resistance of the pile foundation and improving the stability of the pile foundation.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: since the pile foundation is buried below the ground, the contact area between the bottom of the pile foundation and the ground is small, which will affect the bearing capacity of the pile foundation, and the weight that the pile foundation currently bears is relatively strong, so settlement problems are prone to occur, which makes the building structure prone to quality problems when in use. Utility Model Content

[0005] The technical problem to be solved by the utility model is that in the prior art, the pile foundation has the disadvantages of being heavy in weight bearing and having a small contact area with the ground, which makes it easy to sink. For this reason, we propose a pile foundation anti-sinking device.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a pile foundation anti-settling device, including a base plate, a pile basic body is fixedly installed inside the base plate, both sides of the base plate are fixedly connected with fixing frames, the inside of the fixing frames are rotatably connected with a first rotating shaft, the surface of the first rotating shaft is fixedly connected with a rotating plate, the inside of the rotating plate is slidably connected with a sliding rod, the top of the sliding rod is fixedly connected with a nail plate, the bottom of the sliding rod is fixedly connected with a supporting seat, the bottom end of the supporting seat is provided with steel spikes, and the number of the steel spikes is several and evenly distributed on the bottom of the supporting seat.

[0007] Preferably, the front end of the fixing frame is fixedly connected to a fixing rod, the surface of the fixing rod is slidably connected to a connecting plate, the end of the connecting plate away from the fixing rod is fixedly connected to a connecting rod, the end of the connecting rod away from the connecting plate is fixedly connected to a clamping block, and the inner wall of the clamping block is plugged into the surface of the rotating plate.

[0008] Preferably, the surfaces of the fixing rods are slidably connected with tension springs, the ends of the tension springs close to the fixing frame are fixedly connected to the fixing frame, and the ends of the tension springs away from the fixing frame are fixedly connected to the connecting plate.

[0009] Preferably, one end of the fixing rod away from the fixing frame is fixedly connected to a limiting plate, and the limiting plate is circular in shape.

[0010] Preferably, a clamping ring is provided on the surface of the pile basic body, and the interior of the front end and the rear end of the clamping ring are rotatably connected to the support rod, and a fixing seat is provided on the top of the base plate. The number of the fixing seats is four and they are evenly distributed on the top of the base plate, and one end of the fixing seat close to the support rod is fixedly connected to a second rotating shaft, and the surface of the second rotating shaft is rotatably connected to the interior of the support rod.

[0011] Preferably, the internal thread of the fixing seat is connected with a bolt, and the top of the bolt is fixedly connected with a nut.

[0012] Technical effects and advantages of the utility model:

[0021] Reference Figure 1-4 As shown, the utility model provides a technical solution: a pile foundation anti-settling device, including a base plate 1, a pile basic body 2 is fixedly installed inside the base plate 1, both sides of the base plate 1 are fixedly connected with a fixing frame 3, the inside of the fixing frame 3 is rotatably connected with a first rotating shaft 4, the surface of the first rotating shaft 4 is fixedly connected with a rotating plate 5, the inside of the rotating plate 5 is slidably connected with a sliding rod 6, the top of the sliding rod 6 is fixedly connected with a nail plate 7, the bottom of the sliding rod 6 is fixedly connected with a supporting seat 8, the bottom end of the supporting seat 8 is provided with steel spikes 9, and the number of steel spikes 9 is several and evenly distributed at the bottom of the supporting seat 8.

[0022] The following is a detailed description of the specific settings and functions of the positioning mechanism and the anti-deviation mechanism.

[0023] Reference Figure 1 , Figure 2As shown, in this embodiment: the user drives the sliding rod 6 to rotate inside the fixing frame 3 by pulling the rotating plate 5, so that the supporting seat 8 drives the steel spike 9 to be inserted into the ground. By inserting the steel spike 9 into the ground, the contact surface between the pile basic body 2 and the soil can be increased through the supporting seat 8, thereby increasing the support for the pile basic body 2, avoiding the pile basic body 2 from sinking due to the reduction of the friction between the pile basic body 2 and the soil, thereby effectively enhancing the stability of the placement of the pile basic body 2, and convenient to use. The front end of the fixing frame 3 is fixedly connected with a fixing rod 10, and the surface of the fixing rod 10 is slidably connected with a connecting plate 11, and the end of the connecting plate 11 away from the fixing rod 10 is fixedly connected with a connecting rod 12, and the end of the connecting rod 12 away from the connecting plate 11 is fixedly connected with a clamping block 13, and the inner wall of the clamping block 13 is plugged into the surface of the rotating plate 5. By setting structures such as the connecting plate 11, the connecting rod 12, and the clamping block 13, The horizontal position of the rotating plate 5 is effectively limited, and the surface of the fixing rod 10 is slidably connected with a tension spring 14, and the end of the tension spring 14 close to the fixing frame 3 is fixedly connected to the fixing frame 3, and the end of the tension spring 14 away from the fixing frame 3 is fixedly connected to the connecting plate 11. By setting the tension spring 14, when the user pulls the connecting plate 11 to drive the connecting rod 12 to move, the block 13 is driven to move at the same time, and the tension spring 14 starts to accumulate force. When the rotating plate 5 needs to be limited, the rebound force of the tension spring 14 drives the connecting plate 11 to push the connecting rod 12 to pull the block 13 to plug the rotating plate 5, which greatly saves manpower. The end of the fixing rod 10 away from the fixing frame 3 is fixedly connected to the limiting plate 15, and the shape of the limiting plate 15 is circular. By setting the limiting plate 15, the connecting plate 11 is prevented from falling off when the surface of the fixing rod 10 moves, thereby improving the stability of the device.

[0024] Reference Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment: a clamping ring 16 is provided on the surface of the pile basic body 2, and the front and rear ends of the clamping ring 16 are rotatably connected to the inside of the support rod 17, and a fixing seat 18 is provided on the top of the base plate 1. The number of the fixing seats 18 is four and they are evenly distributed on the top of the base plate 1, and the ends of the fixing seats 18 close to the support rod 17 are fixedly connected to the second rotating shaft 19, and the surface of the second rotating shaft 19 is rotatably connected to the inside of the support rod 17. By arranging structures such as the clamping ring 16, the support rod 17, and the fixing seat 18, the supporting capacity of the pile basic body 2 is improved, and at the same time, the vertical direction of the pile basic body 2 is prevented from being offset, which can increase the stability and load-bearing capacity of the device, and has a certain anti-deformation effect. The internal thread of the fixing seat 18 is connected with a bolt 20, and the top of the bolt 20 is fixedly connected with a nut 21. By arranging the structure of the bolt 20 and the nut 21, the fixing seat 18 is fixed to make the device more stable.

[0025] The practical working principle of the present invention is that the user drives the sliding rod 6 to rotate inside the fixing frame 3 by pulling the rotating plate 5, so that the supporting seat 8 drives the steel spike 9 to be inserted into the ground. By inserting the steel spike 9 into the ground, the contact surface between the pile basic body 2 and the soil can be increased through the supporting seat 8, thereby increasing the support for the pile basic body 2, avoiding the pile basic body 2 from sinking due to the reduction of the friction between the pile basic body 2 and the soil, thereby effectively enhancing the stability of the pile basic body 2. It is easy to use, and the horizontal position of the rotating plate 5 is effectively limited by setting structures such as the connecting plate 11, the connecting rod 12, and the clamping block 13. By setting the tension spring 14, when the user pulls the connecting plate 11 to drive the connecting rod 12 to move, the clamping block 13 is also driven to move. The tension spring 14 begins to accumulate force. When the rotating plate 5 needs to be limited, the rebound force of the tension spring 14 drives the connecting plate 11 to push the connecting rod 12 to pull the block 13 to plug the rotating plate 5, which greatly saves manpower. By setting the limiting plate 15, the connecting plate 11 is prevented from falling off when moving on the surface of the fixing rod 10, and the stability of the device is improved. By setting structures such as the retaining ring 16, the support rod 17, and the fixing seat 18, the supporting capacity of the pile basic body 2 is improved, and at the same time, the vertical direction of the pile basic body 2 is prevented from being offset, which can increase the stability and load-bearing capacity of the device and has a certain anti-deformation effect. By setting the structure of the bolt 20 and the nut 21, the fixing seat 18 is fixed to make the device more stable.
