[0002] A pile foundation refers to a deep foundation consisting of a pile and a pile cap (referred to as the cap) connected to the pile top, or a single pile foundation consisting of a column connected to the pile base. Pile foundations are an ancient type of foundation. Pile construction technology has undergone thousands of years of development. Pile foundation materials and types, as well as pile-driving machinery and construction methods, have all undergone significant advancements, forming a modern foundation engineering system. In certain situations, the use of pile foundations can significantly reduce construction site workload and material consumption. Application No. CN202121834468.2 discloses a special-shaped pile cap structure with prestressed steel bars. The cap comprises a special-shaped cap, a cross-section pile body, and a tapered pile head. The special-shaped cap is triangular, with prestressed high-strength steel bars placed in the middle. The cross-section of the special-shaped pile is improved by the special-shaped pile body. However, the structure is complex, with curved surfaces and cavities, which require cumbersome processing. The manufacturing process is complex, increasing manufacturing costs. Therefore, we have introduced a pile cap structure. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] See also Figures 1-4 , the utility model provides a technical solution:

[0022] A pile foundation pedestal structure includes a pedestal body 1, wherein an upper structure 2 is mounted and connected to the upper end of the pedestal body 1, and three pile mechanisms 3 are mounted and connected to the lower end of the pedestal body 1. The three pile mechanisms 3 are distributed in an equilateral triangle.

[0023] In this embodiment, the pile body mechanism 3 includes a pile body 31, and three steel plates 32 are fixedly connected to the outer surface of the pile body 31. The three steel plates 32 are distributed in an equidistant ring. A number of columns 34 are inserted and fixedly connected to the three steel plates 32. A number of through holes 33 are opened on the three steel plates 32. The lower end of the pile body 31 and the lower ends of the three steel plates 32 are jointly fixedly connected to a pile head 35; the pile head 35 is a structure that is wide at the top and narrow at the bottom; a number of through holes 33 and a number of columns 34 are staggered; the pile body 31 and the three steel plates 32 are jointly installed at the lower end of the base body 1; the diameter of the upper end of the pile head 35 is larger than the diameter of the pile body 31.

[0024] Through the above solution: the three steel plates 32 form support for the pile body 31, thereby improving the strength of the pile body 31. After backfilling, the backfill fills the through holes 33 opened on the steel plates 32, and cooperates with the several columns 34 on the steel plates 32 to improve the tensile resistance of the pile body 31.

[0025] It should be noted that the present invention describes a pile foundation pedestal structure, which enhances the overall structural strength of the pile body 31 by installing three steel plates 32 evenly distributed in a ring shape on the outer surface of the pile body 31. It effectively resists the lateral pressure from the surrounding soil layer and the potential risk of deformation. A number of through holes 33 and a number of columns 34 are provided on the three steel plates 32. The existence of the through holes 33 allows the backfill material to penetrate smoothly and fill the gaps tightly. Once the backfill solidifies, it forms an inseparable whole with the pile body 32, greatly improving the overall stability. The setting of the columns 34, which penetrate deep into the backfill material, provides the pile body 31 with additional grip and pull-out resistance, further ensuring the stability of the pile body under complex geological conditions. Its structure is simple and clear, and does not require complicated processing procedures, thereby effectively reducing the manufacturing cost, making this type of pile show excellent adaptability in areas where the soil structure is not dense enough, such as beaches and artificial islands.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
