Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a support structure for pile foundations. Background Technology

[0002] Pile foundations are a common foundation engineering technique used to increase the bearing capacity or stability of soil. When the bearing capacity of underground soil is low or the soil is loose, pile foundations can provide more reliable support by penetrating deeper into more stable soil or rock layers. For high-rise buildings, large bridges, overpasses, dams and other structures with large loads, pile foundations can effectively distribute the load, reduce the bearing pressure of the foundation, and ensure the stability and safety of the structure. The use of pile foundations can reduce structural damage and deformation caused by foundation settlement.

[0003] A search revealed that patent number "CN216108588U" states that "This utility model relates to the field of construction, specifically a support structure for pile foundations, including a foundation, a pile cap movably connected to the top of the foundation, a pile column fixedly connected to the bottom of the pile cap, a rotating groove formed on the top of the pile cap, a bearing embedded in the inner wall of the rotating groove, and a rotating rod fixedly connected to the inner ring of the bearing. This utility model, by setting up a foundation, pile cap, fixed column, first spring, and support plate, connects the first spring to the support plate. The first spring is in a compressed state, and its elastic force applies downward pressure to the pile cap, making the contact between the pile cap and the top of the foundation more compact. This achieves a supporting function for the device, preventing it from failing to provide adequate support on sloping ground, thus expanding the device's application range and greatly..." This significantly improves the practicality of the device, thereby effectively increasing its utilization rate. In use, it consists of a foundation, a pile cap, a fixed column, a first spring, and a support plate. The first spring is connected to the support plate, and when compressed, its elastic force applies downward pressure to the pile cap, ensuring a tighter contact between the pile cap and the top of the foundation. This provides support and prevents the device from failing to provide adequate support on sloping ground, thus expanding its application range and greatly improving its practicality and utilization rate. However, the device's pile foundation balance support structure is difficult to disassemble and replace, and it primarily provides bottom support, lacking a higher external auxiliary support structure and sufficient stability to maintain the balance and limiting support for the retaining piles.

[0023] Example 1

[0024] Please see Figure 1-4As shown, this utility model provides a technical solution: a support structure for pile foundation, including a pile body 1 and a fixing mechanism 2, wherein the fixing mechanism 2 is installed on the outer side of the pile body 1.

[0025] The fixation mechanism 2 includes a clamping component 21, a fixing component 22, a rotating component 23, an extension component 24, and a locking component 25. The clamping component 21 is installed on the outside of the pile body 1, the fixing component 22 is installed on the top of the clamping component 21, the rotating component 23 is installed on one side of the clamping component 21, the extension component 24 is installed on the inside of the rotating component 23, and the locking component 25 is installed at one end of the extension component 24.

[0026] Furthermore, the clamping assembly 21 includes an elastic friction pad 211 and an arc plate 212. The elastic friction pad 211 abuts against the outer side of the pile body 1, and the arc plate 212 is bonded to the other side of the elastic friction pad 211. The elastic friction pad 211 increases the friction force, and the arc plate 212 provides a connection support relationship for other components.

[0027] Furthermore, the fixing component 22 includes a support plate 221 and a limiting screw 222. The top end of the arc plate 212 is fixedly connected to the support plate 221, and the two sides of the support plate 221 are threadedly connected to the limiting screw 222. The two sets of support plates 221 are connected by the limiting screw 222, which facilitates disassembly and assembly and can adapt to the clamping range according to the different diameters of the pile body 1.

[0028] Furthermore, the rotating assembly 23 includes a slide 231 and a limiting hole 232. The slide 231 is rotatably connected to one side of the arc plate 212 via a shaft. The limiting hole 232 is provided on the surface of the slide 231. The support angle is adjusted by the rotation structure of the slide 231 and the arc plate 212. The limiting hole 232 facilitates the slide 231 to fix the limiting rod 252.

[0029] Furthermore, the extension assembly 24 includes an extension rod 241 and a sleeve rod 242. The extension rod 241 is slidably connected to the inner side of the carriage 231, and the sleeve rod 242 is fixedly connected to one end of the extension rod 241. The extension rod 241 extends the support length to adapt to different ground levels, and the sleeve rod 242 prevents the limiting rod 252 from shifting.

[0030] Furthermore, the locking assembly 25 includes a spring 251 and a limiting rod 252. The spring 251 is fixedly connected to the inner side of the sleeve rod 242. One end of the spring 251 is fixedly connected to the limiting rod 252. The spring 251 pushes the limiting rod 252 through the limiting hole 232, so that the limiting rod 252 is fixed in position with the slide 231.

[0031] Example 2

[0032] Please see Figure 2As shown in the first embodiment, as another implementation of this utility model, the other end of the extension rod 241 is equipped with a ground spike assembly 3. The ground spike assembly 3 includes a connecting block 31 and a cone 32. The other end of the extension rod 241 is threadedly connected to the connecting block 31, and the other end of the connecting block 31 is fixedly connected to the cone 32. The threaded structure between the connecting block 31 and the extension rod 241 facilitates disassembly and assembly, and the cone 32 is driven into the ground for stable support.

[0033] Furthermore, an auxiliary component 4 is installed on the outside of the connecting block 31. The auxiliary component 4 includes a plate 41 and a friction plate 42. The plate 41 is rotatably connected to the outside of the connecting block 31 via a shaft. The friction plate 42 is attached to the bottom of the plate 41. The four sets of plates 41 rotate outward to fit against the external ground. The friction plate 42 increases the friction and strengthens the stability of the support.

[0034] Working principle: First, a pile foundation support structure is moved to the working position. In use, the first step is to place two sets of elastic friction pads 211 against the outside of the pile body 1 in opposite directions. The two sets of support plates 221 are displaced in opposite directions by the limiting screw 222, so that the two sets of arc plates 212 clamp the pile body 1. The second step is to adjust the support angle by rotating the slide 231 and the arc plate 212. Press the limiting rod 252 to disengage it from the limiting hole 232. Stretch the extension rod 241 to adjust the support length. Without external force, the spring 251 pushes the limiting rod 252 through the limiting hole 232, so that the position of the limiting rod 252 and the slide 231 is fixed. The third step is to facilitate disassembly and assembly by the threaded structure of the connecting block 31 and the extension rod 241. The cone 32 is driven into the ground to stabilize the support. The fourth step is to rotate the four sets of plates 41 outward to fit against the external ground. The friction plate 42 increases the friction and strengthens the stability of the support. This completes the use process of the pile foundation support structure.
