[0002] A pile foundation is a deep foundation consisting of piles and a pile cap connecting the pile tops, or a single pile foundation consisting of a column connected to the piles. If the entire pile is embedded in the soil and the bottom of the pile cap is in contact with the soil, it is called a low-pile-cap pile foundation; if the upper part of the pile is exposed above the ground and the bottom of the pile cap is above the ground, it is called a high-pile-cap pile foundation. Building pile foundations are usually low-pile-cap pile foundations. Pile foundations are widely used in high-rise buildings.

[0003] In existing technologies, when providing support for buildings with large spans, it is necessary to provide support through pile foundations. Pile foundations can transfer the load of the building to a deep and stable foundation. By utilizing the characteristic of pile foundations being buried deep underground, they can withstand vertical pressure, horizontal force and uplift force, ensuring the safety and durability of the building structure under large spans.

[0004] However, when providing support through pile foundations, the support is provided to the building by driving the pile foundations to a certain depth. As the pressure on the building increases, the side friction of the pile foundations may decrease, and the load borne by the pile foundations may not be effectively transferred to the surrounding soil, leading to an increase in the settlement of the pile foundations or even uneven settlement.

[0007] In a preferred embodiment, the protective mechanism includes an anti-collision shell, a back plate is provided on one side of the anti-collision shell, and one side of the anti-collision shell contacts one side of the back plate.

[0008] In a preferred embodiment, a rectangular cavity is provided at one end of the back plate, and one end of the back plate is fixedly connected to one end of the rectangular cavity. One end of the rectangular cavity is in contact with one end of the anti-collision shell, and the anti-collision shell covers the outer side of one end of the lead screw.

[0009] In a preferred embodiment, the bottom side of the inner frame is slidably connected to the inside of the rectangular cavity, and the inner wall of the rectangular cavity is threadedly connected to the outer side of the lead screw.

[0010] In a preferred embodiment, a splicing ring is provided on one side of the rectangular cavity, and one side of the rectangular cavity is fixedly connected to one end of the splicing ring. An arc-shaped plate is provided on one inner wall of the splicing ring, and one inner wall of the splicing ring is rotatably connected to one end of the arc-shaped plate. A rod is provided on the inner wall of the arc-shaped plate, and the inner wall of the arc-shaped plate is slidably connected to the outer side of the rod.

[0011] In a preferred embodiment, a connecting rod is provided on one side of the insertion rod, and one side of the insertion rod is fixedly connected to one end of the connecting rod. The outer side of the connecting rod is slidably connected through the inner wall of the arc-shaped plate.

[0025] Example 1

[0026] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: a building pile foundation anti-settlement support structure, including an anti-settlement mechanism 1, a protective mechanism 2 at one end of the anti-settlement mechanism 1, the anti-settlement mechanism 1 including a pile foundation body 11, a fixing ring 12 on the outer side of the pile foundation body 11, the outer side of the pile foundation body 11 being fixedly connected to the inner side of the fixing ring 12, a fixing plate 13 on the inner wall of the fixing ring 12, the inner wall of the fixing ring 12 being fixedly connected to the outer side of one end of the fixing plate 13, a support rod 14 on the inner side of the fixing plate 13, the inner side of the fixing plate 13 being rotatably connected to the top end of the support rod 14, an inner frame 16 on the bottom end of the support rod 14, the bottom end of the support rod 14 being rotatably connected to the inner side of the inner frame 16, a screw rod 17 on one end of the inner frame 16, one end of the inner frame 16 being rotatably connected to one end of the screw rod 17, a sliding connection between the bottom side of the inner frame 16 and the interior of a rectangular cavity 18, a threaded connection between the inner wall of the rectangular cavity 18 and the outer side of the screw rod 17, and a side surface of one end of the rectangular cavity 18 being provided with The assembly includes a splicing ring 19. One side of a rectangular cavity 18 is fixedly connected to one end of the splicing ring 19. An arc-shaped plate 110 is provided on one inner wall of the splicing ring 19, and one end of the arc-shaped plate 110 is rotatably connected to the inner wall of the splicing ring 19. An insertion rod 111 is provided inside the arc-shaped plate 110, and the inside of the arc-shaped plate 110 is slidably connected to the outside of the insertion rod 111. A connecting rod 112 is provided on one side of the insertion rod 111, and one end of the insertion rod 111 is fixedly connected to one end of the connecting rod 112. The outer side of the connecting rod 112 is slidably connected to the inner wall of the arc plate 110. One end of the connecting rod 112 is provided with a side plate 113. One end of the connecting rod 112 is fixedly connected to one side of the side plate 113. One side of the side plate 113 is slidably contacted with the outer arc surface of the arc plate 110. The top end of the support rod 14 is provided with a positioning pin 15. The top end of the support rod 14 is connected to the outer side of the positioning pin 15. The outer side of the positioning pin 15 is connected to the inner wall of the fixing plate 13.

[0027] In this embodiment, when using this type of building pile foundation anti-settlement support structure, firstly, a fixing ring 12 is installed on the outside of the pile foundation body 11. The fixing ring 12 and the pile foundation body 11 are integrated using a mold. A fixing plate 13 is designed on the inner wall of the fixing ring 12. The fixing plate 13 serves as a connector between the support rod 14 and the fixing ring 12. The strength of the fixing plate 13 is generally higher than that of the fixing ring 12. Therefore, by contacting the top of the support rod 14 with the inner side of the fixing plate 13, and with communicating holes on the support rod 14 and the fixing plate 13, the positioning pin 15 is passed through the fixing plate 13 and the support rod 14 to complete the structural connection. An inner frame 16 is designed at the bottom of the support rod 14. The bottom of the support rod 14 is connected to the inner side of the inner frame 16 by a bearing. A rectangular cavity 18 is slidably connected to the outer side of the 6. The inner frame 16 can slide short distance inside the rectangular cavity 18. Then, by turning the lead screw 17, the lead screw 17 and the rectangular cavity 18 are threaded together. At the same time, the inner frame 16 slides, causing the support rod 14 to change angle. After the lead screw 17 stops, the angle of the support rod 14 can be fixed. Since the angle of the support rod 14 is fixed, when the pile foundation body 11 is under pressure, the support rod 14 will bear part of the pressure. At the same time, the support rod 14 is located on the ground, while the pile foundation body 11 is located in the soil. The pressure on the pile foundation body 11 is distributed to the ground support structure. By utilizing the rigid support and fixed angle characteristics of the support rod 14, the vertical pressure is transformed into a cooperative force between the support rod 14 and the pile foundation body 11.

[0028] A splicing ring 19 is installed on the outer side of one end of the rectangular cavity 18. There are two splicing rings 19, which are connected by bolts so that the two splicing rings 19 form a ring when they are joined together. The splicing ring 19 contacts the ground, which can enhance the contact stability with the ground. At the same time, the symmetry of the ring structure can be used to distribute the pressure transmitted by the support rod 14 evenly on the ground surface. An arc plate 110 is designed on the inner wall of one side of the splicing ring 19. By unfolding the arc plate 110, the contact area with the ground is increased, reducing the unit pressure on the ground. Furthermore, an insertion rod 111 is installed on the inner wall of the arc plate 110. The insertion rod 111 is fixedly connected to the side plate 113 through the connecting rod 112. Then, after the arc plate 110 is unfolded, the side plate 113 is subjected to downward pressure, which causes the insertion rod 111 to enter the soil. The soil friction is used to enhance the pull-out resistance and lateral displacement resistance of the entire support structure.

[0029] Example 2

[0030] like Figure 1As shown, the protective mechanism 2 includes an anti-collision shell 21. A back plate 22 is provided on one side of the anti-collision shell 21. One side of the anti-collision shell 21 contacts one side of the back plate 22. A rectangular cavity 18 is provided at one end of the back plate 22. One end of the back plate 22 is fixedly connected to one end of the rectangular cavity 18. One end of the rectangular cavity 18 contacts one end of the anti-collision shell 21. The anti-collision shell 21 covers the outside of one end of the lead screw 17.

[0031] In this embodiment, since the lead screw 17 is installed in the rectangular cavity 18, a back plate 22 is fixedly connected to one end of the rectangular cavity 18, and an anti-contact shell 21 is designed on one side of the back plate 22. By aligning the anti-contact shell 21 with the lead screw 17 and then moving it in the corresponding manner, the anti-contact shell 21 comes into contact with the back plate 22. At the same time, the anti-contact shell 21 covers the turning end of the lead screw 17. At this time, the back plate 22 and the anti-contact shell 21 are connected by bolts to form a closed protective structure for the lead screw 17, preventing construction personnel from accidentally touching the lead screw 17 and causing it to loosen, which would reduce the pressure resistance of the support rod 14.

[0032] Working principle:

[0033] like Figure 1 - Figure 4 As shown, by contacting the top of the support rod 14 with the inner side of the fixing plate 13, and the support rod 14 and the fixing plate 13 having communicating holes, the structural connection is completed by passing the positioning pin 15 through the fixing plate 13 and the support rod 14. By turning the screw rod 17, the screw rod 17 and the rectangular cavity 18 are threaded together, and the inner frame 16 slides, causing the support rod 14 to change angle. After the screw rod 17 stops, the angle change of the support rod 14 can be fixed. Since the angle of the support rod 14 is fixed, when the pile foundation body 11 is under pressure, the support rod 14 will bear part of the pressure, distributing the pressure on the pile foundation body 11 to the ground. Secondly, by unfolding the arc plate 110 inside the splicing ring 19, the contact area with the ground is increased. Finally, pressure is applied to the side plate 113 to insert the rod 111 into the soil, thus fixing the overall structure.

[0034] By aligning the anti-collision shell 21 with the lead screw 17 and then moving it in the corresponding manner, the anti-collision shell 21 comes into contact with the back plate 22. At the same time, the anti-collision shell 21 covers the turning end of the lead screw 17. Then, by using bolts to connect the back plate 22 and the anti-collision shell 21, a closed protective structure for the lead screw 17 is formed, preventing construction personnel from accidentally touching the lead screw 17 and causing it to loosen.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
