Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a prefabricated multi-pile foundation structure. Background Art

[0002] In the traditional construction industry, the design and construction of foundations are crucial links that directly affect the stability and safety of building structures. For large or high-rise buildings, especially in areas with complex geological conditions and high bearing capacity requirements, how to effectively enhance the bearing capacity and stability of the foundation has become an urgent problem to be solved.

[0003] In traditional pile foundation structures, pile structures are mostly cylindrical structures. When subjected to external loads, they are prone to slippage or settlement, affecting the overall stability of the building. To this end, we proposed a prefabricated multi-pile foundation structure, which increases the contact area between each group of pile components and the soil layer by setting serrated convex strips on the outside of the pile structure, thereby increasing the friction between the two, obtaining better grip, and reducing the risk of pile slippage. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a prefabricated multi-pile foundation structure, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a prefabricated multi-pile foundation structure, comprising:

[0006] Pile body components, multiple groups of pile body components are circumferentially distributed with equal spacing;

[0007] The convex strips are respectively fixed on the outer surface of the pile body of each pile body assembly, and each group of the convex strips has a serrated structure. The contact area between each pile body assembly and the soil layer is increased by the multiple groups of convex strips, thereby increasing the friction between the two, obtaining better grip, and reducing the risk of pile body slippage.

[0008] Furthermore, the prefabricated multi-pile foundation structure further comprises:

[0009] A cap assembly, wherein the cap assembly is arranged on the upper part of the plurality of pile assembly groups;

[0010] Nuts, multiple groups of nuts are threadedly connected to the upper parts of multiple groups of pile body components, and the base assembly and the multiple groups of pile body components form a fixed structure through the multiple groups of nuts.

[0011] Furthermore, the pile assembly comprises:

[0012] The prefabricated pile consists of a pile head, a pile body and a pile tip. The pile body is a cylindrical structure, and the pile head and the pile tip are conical structures. The diameter of the pile head is larger than the diameter of the pile body to increase the contact area between the pile head and the soil layer and improve the bearing capacity.

[0013] Furthermore, the pile assembly also includes:

[0014] A connecting groove, wherein the connecting groove is provided on the upper part of the prefabricated pile;

[0015] The screw rod is fixed inside the precast pile, and the free end of the screw rod extends above the precast pile. Each set of nuts is threadedly connected to the outside of the screw rod.

[0016] Furthermore, the platform assembly includes:

[0017] A prefabricated cap, the bottom end of which is in contact with the top ends of the plurality of groups of prefabricated piles;

[0018] Connecting blocks, multiple groups of connecting blocks are fixed at the lower part of the prefabricated support, and are circular and evenly spaced. The prefabricated support and the multiple groups of connecting blocks are an integrated structure. The multiple groups of connecting blocks are respectively located inside the multiple groups of connecting grooves, and have matching sizes.

[0019] Furthermore, the platform assembly also includes:

[0020] Through holes, multiple groups of through holes are opened on the prefabricated support platform and multiple groups of connecting blocks, and the free ends of the multiple groups of screw rods pass through the multiple groups of through holes respectively.

[0021] Compared with the above-mentioned background technology, the prefabricated multi-pile foundation structure provided by the present application includes a pile body assembly, a convex strip, a base assembly and a nut. The serrated convex strip can increase the contact area between the pile body assembly and the soil layer, thereby increasing the friction between the two. This increased friction helps the pile body assembly to obtain better grip in the soil layer, and when bearing external loads, it can more stably transfer the load to the soil layer, thereby reducing the possibility of slippage of the pile body assembly.

[0022] The utility model provides a prefabricated multi-pile foundation structure. Compared with the prior art, it has the following beneficial effects:

[0023] 1. A prefabricated multi-pile foundation structure, which effectively increases the contact area between the pile body assembly and the soil layer by arranging serrated convex strips on the outside of the prefabricated piles, thereby increasing the friction between the two, so that the pile body assembly can obtain better grip in the soil layer, and when bearing external loads, it can more stably transfer the load to the soil layer, significantly reducing the possibility of slippage of the pile body assembly and improving the bearing capacity and stability of the foundation.

[0024] 2. A prefabricated multi-pile foundation structure adopts modular component design such as pile body components, base components and nuts, so that the entire structure can be easily prefabricated in the factory, reducing the difficulty and complexity of on-site construction and facilitating transportation. Through simple bolt connection, the base components and multiple groups of pile body components can be quickly assembled and disassembled, which greatly improves construction efficiency and reduces construction costs.
