Description

Technical Field

[0001] This utility model relates to the field of pile foundation technology, specifically to a low-settlement, high-bearing-capacity pile foundation structure. Background Technology

[0002] Pile foundations are a common type of foundation engineering structure used to support buildings or other engineering structures. They mainly consist of a series of piles vertically embedded in the ground. A pile is a long, narrow concrete, reinforced concrete, or steel component formed by drilling or excavating holes in the ground and then pouring concrete into them.

[0003] The utility model patent application with publication number "CN219952016U" discloses a pile foundation structure, which mainly consists of a pile cap body, a sinking cylinder, a cone head, a rectangular shell, a rectangular threaded tube, and a threaded column. This technical solution operates by rotating the threaded column, causing the rectangular threaded tube to move downward under the limitation of the rectangular shell. The rectangular shell then pushes the cone block to slide outward in the inner cavity of the U-shaped shell through a push arm, causing the cone block to embed itself into the soil. This increases the friction between the sinking cylinder and the ground, effectively preventing the sinking cylinder from slipping off the ground, thereby ensuring the stability of the pile cone body and achieving the goal of high stability.

[0004] The pile foundation structure disclosed in the aforementioned document has the following defects: During use, the pile foundation structure is operated by rotating the threaded column, causing the rectangular threaded tube to move downward under the constraint of the rectangular shell. The rectangular shell then pushes the cone block to slide outward in the inner cavity of the U-shaped shell through the push arm, causing the cone block to embed itself in the soil. This increases the friction between the sinking cylinder and the ground, effectively preventing the sinking cylinder from slipping off the ground and thus ensuring the stability of the pile cone body. However, this pile foundation structure cannot support the pile cone. Over long-term use, due to the accumulation of time and the pressure from the superstructure, the pile foundation will tilt at an angle when it settles downward.

[0005] Therefore, it can be seen that the existing pile foundation structure does not have a good supporting effect, and it is necessary to improve the existing shortcomings and provide a pile foundation structure with low settlement and high bearing capacity. Utility Model Content

[0006] The purpose of this invention is to provide a low-settlement, high-bearing-capacity pile foundation structure to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a low-settlement, high-bearing-load pile foundation structure, comprising pile foundation concrete, a pile cap concrete on the upper surface of the pile foundation concrete, a base concrete on the upper surface of the pile cap concrete, two sets of support components on the outer surface of the base concrete, each support component including a base, a groove on the upper surface of the base, a first slider slidably connected inside the groove, a first connecting block hinged to the upper surface of the first slider, a support plate fitted onto the outer surface of the base concrete, a second connecting block hinged to the outer surface of the support plate, and a support rod between the first connecting block and the second connecting block.

[0009] Furthermore, the upper surface of the base is provided with several threaded holes, and the upper surface of the first slider is provided with a connecting plate.

[0010] Furthermore, the peripheral surface of the pile foundation concrete is provided with several barbs.

[0011] Furthermore, the upper surface of the concrete foundation is provided with an installation groove, and the lower surface of the base is provided with an installation block, which is installed in conjunction with the installation groove.

[0012] Furthermore, the upper surface of the base is provided with a through groove, and a second slider is slidably connected inside the through groove. The upper surface of the second slider is provided with a support frame, and the upper surface of the support frame is provided with a mounting hole. One end of the mounting hole passes through the second slider and extends downward. A threaded rod is threadedly connected inside the mounting hole, and a rotating handle is installed at one end of the threaded rod.

[0013] Furthermore, a limiting groove is formed on the inner surface of the through groove, a limiting block is provided on the outer surface of the second slider, the limiting block is slidably connected inside the limiting groove, and a side plate is installed at one end of the base.

[0014] This utility model has the following beneficial effects:

[0015] (1) This utility model tightens the bolts on the two sets of connecting plates so that the bolts are installed in the corresponding threaded holes, thereby fixing the two first sliders in the corresponding sliding grooves. Then, the two support plates are attached to the outer surface of the foundation concrete. The two support plates are fixed together by the cooperation of the screw and nut, which can complete the support of the foundation concrete. This avoids the pile foundation from tilting at an angle when it settles downwards due to the accumulation of time and the pressure of the building above during long-term use, thus achieving a better support effect.

[0016] (2) This utility model moves the support frame in the through groove to adjust the position of the threaded rod. After the position of the threaded rod is adjusted, the rotating handle is turned so that the rotating handle drives the threaded rod to rotate, so that the threaded rod moves downward in the installation hole and inserts into the ground, increasing the connection of the base to the soil and reducing the settlement of the pile foundation, thus achieving a better anti-settlement effect.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 As shown, this utility model is a low-settlement, high-bearing pile foundation structure, including a pile foundation concrete 1, a pile cap concrete 2 on the upper surface of the pile foundation concrete 1, a base concrete 3 on the upper surface of the pile cap concrete 2, and two sets of support components 4 on the outer surface of the base concrete 3. The support components 4 include a base 401, a groove 402 on the upper surface of the base 401, a first slider 403 slidably connected inside the groove 402, a first connecting block 404 hinged to the upper surface of the first slider 403, a support plate 405 fitted on the outer surface of the base concrete 3, a second connecting block 406 hinged to the outer surface of the support plate 405, and a support rod 407 between the first connecting block 404 and the second connecting block 406.

[0027] The inner surface of the support plate 405 is provided with a rubber pad;

[0028] By tightening the bolts on the two sets of connecting plates 409, the bolts are installed in the corresponding threaded holes 408, thereby fixing the two first sliders 403 in the corresponding sliding grooves 402. Then, the two support plates 405 are attached to the outer surface of the foundation concrete 2, so that the rubber pads are in contact with the foundation concrete 2. The two support plates 405 are fixed together by the use of screws and nuts, thus completing the support for the base concrete 3. When the base concrete 3 settles, it will drive the support plates 405 to move downward. At this time, the friction of the rubber pads will block the downward movement. At the same time, the support rod 407 can distribute the downward gravity on the base 401, thereby dispersing the force and reducing settlement.

[0029] By loosening the bolts on the connecting plate 409, the first slider 403 can slide in the groove 402, thereby adjusting the position and angle of the support rod 407. This allows the support plate 405 to effectively contact the base concrete 3 at different heights, thus providing support and reinforcement for the base concrete 3 at different heights and achieving a good practical effect.

[0030] The upper surface of the base 401 is also provided with several threaded holes 408, and the upper surface of the first slider 403 is provided with a connecting plate 409.

[0031] Several barbs 5 are provided on the periphery of the concrete pile foundation 1;

[0032] By setting multiple barbs 5, the concrete pile 1 can be installed more stably and firmly in the ground, thereby improving the stability of the pile foundation;

[0033] The upper surface of the concrete foundation 2 is provided with an installation groove 201, and the lower surface of the base 401 is provided with an installation block 4010, which is installed in the installation groove 201.

[0034] The upper surface of the base 401 is also provided with a through groove 4011. The second slider 4012 is slidably connected inside the through groove 4011. The upper surface of the second slider 4012 is provided with a support frame 4013. The upper surface of the support frame 4013 is provided with a mounting hole. One end of the mounting hole passes through the second slider 4012 and extends downward. The inside of the mounting hole is threadedly connected with a threaded rod 4014. One end of the threaded rod 4014 is equipped with a rotating handle 4015.

[0035] By moving the support frame 4013, the support frame 4013 can move within the through groove 4011, thereby adjusting the position of the threaded rod 4014. After the position of the threaded rod 4014 is adjusted, the rotating handle 4015 is turned, causing the rotating handle 4015 to drive the threaded rod 4014 to rotate, so that the threaded rod 4014 moves downward within the mounting hole, allowing the threaded rod 4014 to be inserted into the ground, increasing the connection of the base 401 to the soil, and also reducing the settlement of the pile foundation, thus achieving a better anti-settlement effect.

[0036] A limiting groove is provided on the inner surface of the through groove 4011, and a limiting block 4016 is provided on the outer surface of the second slider 4012. The limiting block 4016 is slidably connected inside the limiting groove, and a side plate 4017 is installed at one end of the base 401.

[0037] By using the limit block 4016 in conjunction with the limit groove, the second slider 4012 can be prevented from disengaging from the through groove 4011, thus achieving a good limiting effect.

[0038] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
