Description

Technical Field

[0001] This utility model relates to the field of pile cap technology, and in particular to a pile cap for foundation treatment to prevent settlement. Background Technology

[0002] A pile cap is a structure placed on top of a pile, typically in the shape of an enlarged disc. Its main function is to concentrate and transfer the load of the pile to the surrounding soil, ensuring the stability of the pile foundation. The pile cap is an important part of building foundation engineering. During the construction of building pile foundations, the presence of the pile cap effectively transfers the load of the pile to the foundation soil, thereby improving the stability and safety of the entire structure.

[0003] As a key component connecting the pile foundation to the superstructure, the installation quality and subsequent maintenance of pile caps directly affect the stability of the foundation. However, traditional pile caps are mostly integral cast-in-place structures, requiring on-site formwork, vibration, and curing during construction. Installation positioning relies on manual measurement, resulting in low construction efficiency. Furthermore, for existing building settlement repair, traditional pile caps cannot be disassembled or stacked, requiring complete replacement after foundation excavation. This leads to long maintenance cycles, complex operations, high costs, and the potential for secondary disturbance to surrounding structures. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a foundation treatment pile cap for preventing settlement, which aims to improve the problems of cumbersome construction steps, long cycle, long maintenance time and high maintenance cost of traditional pile caps.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foundation treatment pile cap for preventing settlement, comprising a first pile cap, wherein multiple fixing rings are fixedly connected to the outer wall of the first pile cap, multiple sliders are slidably connected to the inner wall of the fixing rings, a spring is provided on one side of the sliders, a slot is provided on the inner wall of the fixing rings, a rotating shaft and a connecting rod are slidably connected to the inner wall of the sliders, a fixing block is slidably connected to the outer wall of the connecting rod, a limit block is fixedly connected to the outer wall of the fixing block, a second pile cap is slidably connected to the outer wall of the first pile cap, multiple positioning grooves are provided on the outer wall of the fixing rings, and a buffer assembly is provided on the outer wall of the fixing rings.

[0006] Preferably, the buffer assembly includes a buffer layer, the outer wall of the buffer layer is fixedly connected to the outer wall of the fixing ring, the outer wall of the fixing ring is provided with a plurality of alloy springs, the outer wall of the fixing ring is slidably connected with a connecting block, and the outer wall of the fixing ring is fixedly connected with a limit cylinder.

[0007] Preferably, a plurality of the alloy springs are disposed on the outer wall of the connecting block, the inner wall of the connecting block is threadedly connected to a post, and the outer wall of the connecting block is slidably connected to the inner wall of the limiting cylinder.

[0008] Preferably, the outer wall of the buffer layer is slidably connected to the outer wall of the connecting block.

[0009] Preferably, the spring is disposed on the inner wall of the fixed ring, and the outer wall of the slider is slidably connected to the inner wall of the slot and the positioning slot.

[0010] Preferably, the outer walls of the fixing block and the limiting block are fixedly connected to the inner wall of the fixing ring.

[0011] Preferably, the outer wall of one of the rotating shafts is slidably connected to the inner wall of the fixing block, and the outer walls of the plurality of rotating shafts are slidably connected to the inner wall of the connecting rod.

[0012] Preferably, the outer walls of both the first and second pile caps are fixedly connected to multiple steel plates, and the outer wall of the second pile cap is fixedly connected to multiple fixing rings, with the outer walls of the multiple fixing rings slidably connected together.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the positioning groove enables the rapid positioning of the first and second pile caps, reducing installation difficulty. After squeezing the slider to compress the spring, the second pile cap is inserted into the inner wall of the first pile cap through the slider and the limiting groove.

Through the cooperation of multiple fixing rings and multiple steel plates, the contact area between the pile cap and the foundation soil is increased, the friction is increased, thereby reducing the pressure on the foundation soil and distributing the pressure more evenly. The buffer layer and multiple alloy springs work together to absorb the impact force, reduce the impact force, avoid the pile cap cracking caused by rigid transmission, and improve the bearing stability of the foundation and the impact resistance of the structure.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-5 This utility model provides an embodiment of a foundation treatment pile cap for preventing settlement, comprising a first pile cap 1, a plurality of fixing rings 2 fixedly connected to the outer wall of the first pile cap 1, a plurality of sliders 8 slidably connected to the inner wall of the fixing rings 2, a spring 9 provided on one side of each slider 8, a groove 10 formed in the inner wall of the fixing rings 2, a rotating shaft 11 and a connecting rod 12 slidably connected to the inner wall of the sliders 8, a fixing block 13 slidably connected to the outer wall of the connecting rod 12, a limit block 14 fixedly connected to the outer wall of the fixing block 13, a second pile cap 4 slidably connected to the outer wall of the first pile cap 1, and a plurality of positioning... The outer wall of the groove 15 and the fixing ring 2 is provided with a buffer assembly; the spring 9 is provided on the inner wall of the fixing ring 2; the outer wall of the slider 8 is slidably connected to the inner wall of the slot 10 and the positioning groove 15; the outer walls of the fixing block 13 and the limiting block 14 are fixedly connected to the inner wall of the fixing ring 2; the outer wall of one of the rotating shafts 11 is slidably connected to the inner wall of the fixing block 13, and the outer walls of multiple rotating shafts 11 are slidably connected to the inner wall of the connecting rod 12; the outer walls of the first pile cap 1 and the second pile cap 4 are both fixedly connected to multiple steel plates 3, the outer wall of the second pile cap 4 is fixedly connected to multiple fixing rings 2, and the outer walls of multiple fixing rings 2 are slidably connected together.

[0026] Specifically, both the first pile cap 1 and the second pile cap 4 have a fixing ring 2 fixedly connected to their outer walls. During installation, the slider 8 is squeezed to compress the spring 9, causing the slider 8 to slide into the fixing ring 2. Through the cooperation of multiple rotating shafts 11, connecting rods 12, fixing blocks 13, and limiting blocks 14, the slider 8 is limited, ensuring that it is engaged in the slot 10, thus improving the stability of the connection. Then, the fixing ring 2 of the second pile cap 4 is aligned and inserted into the positioning groove 15 of the fixing ring 2 of the first pile cap 1 via the slider 8. The positioning groove 15 enables quick positioning, reducing the difficulty of installation. Then, the slider 8 is released. After block 8, the spring 9 pushes the slider 8 from the inner wall of the fixed ring 2 into the slot 10 of the other fixed ring 2, locking the two fixed rings 2 together, completing the quick connection and locking of the first pile cap 1 and the second pile cap 4. When the building settles and needs repair, the pile caps can be stacked through the connecting components. The stacking method can flexibly increase the number of pile caps according to the foundation settlement. On the one hand, it replaces the traditional complicated repair steps, improves efficiency, and shortens the construction cycle. On the other hand, it solves the problem of difficult repair of existing building settlement, improves maintenance efficiency, and reduces maintenance costs.

[0027] Reference Figure 1 , Figure 2 and Figure 6 The buffer assembly includes a buffer layer 16, the outer wall of which is fixedly connected to the outer wall of a fixing ring 2. The outer wall of the fixing ring 2 is provided with multiple alloy springs 7. A connecting block 5 is slidably connected to the outer wall of the fixing ring 2. A limiting cylinder is fixedly connected to the outer wall of the fixing ring 2. Multiple alloy springs 7 are provided on the outer wall of the connecting block 5. A post 6 is threadedly connected to the inner wall of the connecting block 5. The outer wall of the connecting block 5 is slidably connected to the inner wall of the limiting cylinder. The outer wall of the buffer layer 16 is slidably connected to the outer wall of the connecting block 5.

[0028] Specifically, by increasing the contact area with the foundation soil through the fixing ring 2 and steel plate 3 on the outer wall of the first pile cap 1 and the second pile cap 4, the pressure is dispersed over a wider range, reducing the pressure of the foundation soil. The buffer layer 16 is fixed to the outer wall of the fixing ring 2 of the first pile cap 1 and slidably connected to the connecting block 5. When the pile foundation is impacted, the connecting block 5 is compressed by multiple alloy springs 7, causing the connecting block 5 to slide on the outer wall of the buffer layer 16. At the same time, the connecting block 5 will slide on the inner wall of the limiting cylinder, which limits the movement. The impact force causes the buffer layer 16 to undergo elastic deformation, absorbing the impact force. Meanwhile, the multiple alloy springs 7 on the outer wall of the connecting block 5 deform together with the buffer layer 16, further absorbing the remaining impact force through elastic deformation. With the cooperation of the buffer layer 16 and the alloy springs 7, the impact force transmitted to the pile column 6 is reduced to a minimum, avoiding pile cap cracking caused by rigid impact, extending the service life of the pile cap and reducing the maintenance frequency.

[0029] Working principle: This utility model mainly consists of a first pile cap 1, a second pile cap 4, and a pile column 6. Multiple fixing rings 2 are fixed to the outer wall of the first pile cap 1. Multiple positioning grooves 15 are provided on the outer wall of each fixing ring 2. These positioning grooves 15 facilitate quick positioning and reduce installation difficulty. By squeezing the slider 8 and compressing the spring 9, the spring 9 gains spring force, allowing the slider 8 to slide to the inner wall of the fixing ring 2. Then, the slider 8 of the second pile cap 4 is inserted into the first pile cap 1 through the positioning groove 15. Releasing the slider 8 allows it to return to its original position under the rebound force of the spring 9, sliding from the inner wall of one fixing ring 2 to the inner wall of the other, locking the two fixing rings 2 together. This achieves the locking of the first pile cap 1 and the second pile cap 4. Through the connecting components, pile caps can be stacked, shortening the construction cycle and solving the problem of difficult-to-repair settlement in existing buildings, improving maintenance efficiency and reducing maintenance costs.

[0030] This invention utilizes multiple fixing rings 2 and multiple steel plates 3 on the outer walls of the first pile cap 1 and the second pile cap 4. The cooperation of the fixing rings 2 and steel plates 3 increases the friction with the foundation soil, dispersing the pressure over a wider area and thus reducing the soil pressure. Furthermore, by setting a buffer layer 16 on the outer wall of the first pile cap 1, the buffer layer 16 can absorb the impact force through elastic deformation when the pile foundation is impacted. Simultaneously, multiple alloy springs 7 cooperate, and then the connecting block 5 transmits the impact force to the pile column 6. At this point, the impact force is minimized, thus avoiding pile cap cracking caused by rigid transmission, reducing structural vibration, and improving the foundation bearing stability and structural impact resistance.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
