[0002] Pile foundation is a deep foundation composed of piles and caps, which is widely used in various types of construction and bridge projects. Pile foundation has the advantages of high bearing capacity, good stability, small and uniform settlement, etc. However, in some cases, such as loose foundation treatment, high compressibility of foundation soil layer, insufficient bearing capacity of foundation, etc., the pile foundation may have uneven settlement problems. The pile foundation settlement reinforcement jacking and leveling structure can realize the reinforcement and leveling of the pile foundation, improve the bearing capacity and stability of the pile foundation, reduce the settlement at the same time, and ensure the safety and use function of the building or bridge.

[0003] The existing pile foundation settlement reinforcement jacking and leveling structure has low leveling efficiency and is difficult to respond to foundation settlement quickly and effectively, which directly causes the upper structure to sink or tilt, posing a serious threat to the stability and safety of the building. Secondly, due to the lack of modular or detachable design of the leveling structure, it faces great challenges in later maintenance or replacement of parts, which not only increases maintenance costs and time, but is also likely to cause unnecessary delays to the progress of the entire project. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0029] Refer to the figure Figure 1-5 , which is the first embodiment of the utility model, and provides a pile foundation settlement reinforcement jacking and leveling structure, including a pile column 1, a bearing platform 2 is arranged on the top of the pile column 1, and also includes:

[0030] A fixing mechanism 3, which is arranged below the carrying platform 2;

[0031] An adaptive leveling mechanism 4, which is arranged at the bottom of the fixing mechanism 3;

[0032] The active leveling mechanism 5 is arranged at the bottom of the fixing mechanism 3 , and a guide mechanism 8 is arranged on the side of the active leveling mechanism 5 .

[0033] Specifically, a pile end bearing layer 6 is provided at the bottom end of the pile column 1 , a soft soil reinforcement layer 7 is provided below the bearing platform 2 , and both the adaptive leveling mechanism 4 and the active leveling mechanism 5 are located above the soft soil reinforcement layer 7 .

[0034] Furthermore: pile column 1, as the foundation of the entire structure, goes deep into the ground and directly bears the weight of the superstructure. The bearing platform 2 is a connecting component between the superstructure and the pile column 1, ensuring that the load of the superstructure can be evenly transferred to the pile column 1.

[0035] Specifically, the fixing mechanism 3 includes a fixing ring 301 sleeved on the outside of the pile column 1, the fixing ring 301 is composed of a left ring 302 and a right ring 303, the bottom of the left ring 302 and the right ring 303 are fixedly installed with a fixing sleeve 304, the top of the left ring 302, the right ring 303 and the supporting platform 2 are all provided with a threaded hole 305, and the internal thread of the threaded hole 305 is connected with a bolt 306.

[0036] Furthermore, the fixing mechanism 3 fixes the left ring 302 and the right ring 303 on the bearing platform 2 through bolts 306, and can also fix the entire leveling structure on the pile column 1 to ensure that it will not be displaced or fall off during operation.

[0037] Specifically, a slot 307 is formed on the side of the left ring 302 , and an insertion rod 308 is fixedly installed on the side of the right ring 303 , and the insertion rod 308 is inserted into the inside of the slot 307 .

[0038] Furthermore: the slot 307 is an open slot provided on the side of the left ring 302, and its size and shape match the insertion rod 308. When the left ring 302 and the right ring 303 need to be connected, the insertion rod 308 will be inserted into the slot 307. Through a simple insertion and matching method, a stable connection between the left ring 302 and the right ring 303 is achieved, and it is convenient for the user to disassemble the fixing mechanism 3.

[0039] Specifically, the adaptive leveling mechanism 4 includes a sleeve rod 401 fixedly installed at the bottom of the fixing ring 301, a piston rod 402 is slidably installed inside the sleeve rod 401, a support plate 403 is fixedly installed at the bottom of the piston rod 402, and the support plate 403 is placed above the soft soil reinforcement layer 7. A support spring 404 is sleeved on the outer side of the sleeve rod 401, and the support spring 404 is located between the fixing ring 301 and the support plate 403.

[0040] Furthermore: the adaptive leveling mechanism 4 can automatically compensate for the settlement of the foundation to a certain extent and maintain the stability of the superstructure. When the foundation settles, the fixing ring 301 will drop accordingly. At this time, the support spring 404 will be compressed and generate an upward elastic force, thereby pushing the fixing ring 301 up to achieve automatic leveling.

[0041] Specifically, the active leveling mechanism 5 includes an annular guide rail 501 fixedly installed at the bottom of the fixed ring 301, a slider 502 is slidably installed on the outer side of the annular guide rail 501, a fixed block 503 is fixedly installed at the bottom of the slider 502, a hydraulic rod 504 is fixedly installed at the bottom of the fixed block 503, and a lifting block 505 is fixedly installed at the bottom of the hydraulic rod 504.

[0042] Furthermore: when the adaptive leveling mechanism 4 cannot meet the leveling requirements, the active leveling mechanism 5 can intervene to accurately adjust the height and level of the superstructure by controlling the extension and retraction of the hydraulic rod 504 to ensure that it can maintain a stable level under various working conditions. The annular guide rail 501 provides a stable sliding track for the slider 502 to ensure the stability and accuracy of the slider 502 during the leveling process. The lifting block 505 contacts the foundation and compensates for the unevenness of the foundation through its lifting and lowering movement to achieve the leveling function.

[0043] Specifically, the guide mechanism 8 includes a guide rod 801 fixedly installed on the side of the fixed block 503 , and also includes a slide groove 802 opened on the side of the fixed sleeve 304 , and the end of the guide rod 801 is slidably installed inside the slide groove 802 .

[0044] Furthermore: the guide mechanism 8 is used to limit the movement trajectory of the slider 502 on the annular guide rail 501 to prevent it from deviating or falling off. The guide mechanism 8 realizes the stable sliding of the slider 502 on the annular guide rail 501 through the cooperation of the guide rod 801 and the slide groove 802, thereby ensuring the stability and reliability of the active leveling mechanism 5 during movement, so that it can work accurately and stably.

[0045] Working principle:

[0046] When in use, the fixing mechanism 3 is quickly assembled into a complete fixing ring 301 by the left ring 302 and the right ring 303 through the precise cooperation of the slot 307 and the plug rod 308, and then the fixing ring 301 is accurately sleeved on the outside of the pile column 1; by means of the threaded connection of the bolt 306, the left ring 302, the right ring 303 and the bearing platform 2 are firmly fixed together to ensure that the entire leveling structure is stably attached to the pile column 1; when the foundation settles, the fixing ring 301 sinks synchronously with the pile column 1; at this time, the sleeve rod 401 will descend together with the direction of the piston rod 402, and the support spring 404 will be compressed and generate a reverse elastic force, which pushes the fixing ring 301 to move upward, thereby It automatically compensates for the settlement of the foundation to a certain extent, and effectively maintains the stability of the superstructure; if the automatic compensation ability of the adaptive leveling mechanism 4 is not enough to meet the leveling demand, the active leveling mechanism 5 will be started immediately; by moving the slider 502, adjusting the hydraulic rod 504 to a suitable position, and by accurately controlling the extension and retraction of the hydraulic rod 504, the jacking block 505 is driven to support the foundation, thereby generating a reverse thrust; at the same time, the guide rod 801 is firmly fixed to the side of the fixed block 503, and its end slides stably in the slide groove 802, ensuring that the slider 502 moves smoothly and stably on the annular guide rail 501, effectively preventing it from deflecting or falling off, and further improving the accuracy and reliability of the active leveling mechanism 5.

[0047] In summary: through the clever cooperation of the two leveling mechanisms, various challenges of foundation settlement can be more calmly dealt with to ensure the stability and safety of the building. Through the design of the adaptive leveling mechanism 4, the settlement of the foundation can be automatically compensated. Through the compression and rebound of the support spring 404, the stability of the upper structure can be maintained in real time. This automatic leveling mechanism not only responds quickly, but also can effectively alleviate the impact of foundation changes on the building. However, when the foundation settlement exceeds the compensation capacity of the adaptive leveling mechanism 4, the active leveling mechanism 5 will quickly intervene. With its powerful hydraulic system and precise control system, it can compensate for the settlement of the foundation. The foundation is accurately lifted and leveled to ensure that the building returns to a horizontal state. The combination of this dual mechanism not only greatly improves the leveling efficiency and stability, but also enhances the adaptability and reliability of the entire leveling structure. In addition, through the modular setting of the fixing mechanism 3, the entire leveling structure can be quickly and firmly fixed on the pile 1. This installation method is not only simple and fast, but also ensures the stability of the leveling structure during the construction process. At the same time, the detachable design of the fixing mechanism 3 also greatly improves the flexibility and reusability of the structure, which is convenient for construction and maintenance, and effectively reduces resource waste and environmental pollution.
