Description

Technical Field

[0001] The present application relates to the technical field of pipe piles, and in particular to a composite reinforced concrete pipe pile. Background Art

[0002] In the field of civil engineering, concrete pipe piles, as an important basic engineering material, are widely used in various types of construction, bridges, highways, ports and other engineering projects.

[0003] An existing patent (publication number: CN219772954U) discloses a corrosion-resistant steel composite prestressed concrete pipe pile, comprising a concrete pipe pile and a first screw. A protective device is installed on the outer wall of the concrete pipe pile, and a connecting device is installed below the concrete pipe pile. A first corrosion-resistant layer can be applied to the inner wall of the concrete pipe pile to improve its corrosion resistance. Second and third corrosion-resistant layers are then applied to the outer wall of the steel mesh layer. This double-layer corrosion-resistant structure provides corrosion protection for the outer wall of the concrete pipe pile. Even when the concrete pipe pile is used in coastal areas or strata with high salinity, it is less susceptible to corrosion from chloride and sulfate ions in the environment, thereby extending the overall service life of the concrete pipe pile.

[0004] However, during the use of the above-mentioned pipe piles, under some special geological conditions, such as soft soil foundations or occasions where large vertical loads need to be borne, the pull-out resistance of the concrete pipe piles is directly related to the safety and stability of the project. However, the structural design of the above-mentioned corrosion-resistant steel composite prestressed concrete pipe piles does not fully consider the improvement of the pull-out resistance, which may lead to insufficient pull-out resistance in actual application, thereby affecting the quality and safety of the project. Utility Model Content

[0005] In response to the deficiencies in the prior art, the present application provides a composite reinforced concrete pipe pile, which has the advantages of being easy to produce and having good pull-out resistance, and solves the problems raised in the background art.

[0006] To achieve the above-mentioned object, the present application provides the following technical solution: a composite reinforced concrete pipe pile, comprising a pile body, wherein a steel cage is provided inside the pile body, wherein the steel cage comprises a plurality of steel strands and annular steel wires;

[0007] An inner base layer is provided inside the pile body, an outer base layer is provided on the outer surface of the inner base layer, the steel cage is embedded in the inner base layer, the inner walls of the left and right ends of the pile body are provided with internal threads, the left and right ends of the pile body are threadedly connected to pile heads, the sides of the two pile heads close to each other are rotatably connected to pull plates, the sides of the two pull plates close to each other are fixedly connected to a plurality of circumferentially arranged hanging rings, each of the two steel strands is fixedly connected to a hook at both ends, and each of the hooks is hooked with the hanging ring close to it.

[0008] The above solution, through the anti-slip treatment on the outer surface of the pile body and the variable-section cylindrical pile body design, effectively increases the friction between the pile body and the soil, optimizes the stress state of the pile body in the soil, and significantly improves the pull-out resistance of the concrete pipe pile. It is particularly suitable for soft soil foundations or situations that need to withstand large vertical loads, enhancing the safety and stability of the project. The internal reinforcement cage, including multiple equally spaced circular steel strands and annular steel reinforcing wires, ensures the uniform distribution of the reinforcement cage within the pile body. This design not only improves the bending, compression, and shear resistance of the pile body, but also makes the pile body structure more stable and able to withstand greater external forces. The pile head design adopts an internal thread connection and a hexagonal groove structure, making the installation and removal of the pile head more convenient, not only improving construction efficiency but also reducing the error rate during the installation process, ensuring the quality and progress of the project. The inner base layer is made of high-strength concrete material, and the outer base layer is a glass fiber reinforced polymer composite layer, which effectively protects the pile body from external environmental erosion, such as chemical corrosion and physical wear, and extends its service life.

[0009] Furthermore, the plurality of steel strands are arranged in a circumferential manner with equal distances, each of the annular steel reinforcing wires is fixedly connected to each of the steel strands, and the plurality of annular steel reinforcing wires are arranged in a circumferential manner with equal distances.

[0010] Through the above scheme and the above arrangement, it is possible to ensure that the steel cage is evenly distributed inside the pile body, thereby improving the bending, compression and shearing resistance of the pile body and making the pile body structure more stable.

[0011] Furthermore, the inner base layer is made of high-strength concrete material.

[0012] Through the above scheme and the above arrangement, the internal strength and durability of the pile body can be enhanced, and the bearing capacity of the pile body can be improved.

[0013] Furthermore, the outer base layer is configured as a glass fiber reinforced polymer composite material layer.

[0014] The above solution can protect the pile body from external environmental erosion, such as chemical corrosion, physical wear and tear, and ultraviolet radiation, thereby significantly extending the service life of the pile body.

[0015] Furthermore, a group of casting holes are opened on the outer surface of the pile body.

[0016] Through the above scheme and the above arrangement, it is convenient to inject concrete into the interior of the pile body during the pouring process, ensuring that the interior of the pile body is densely filled and improving the overall performance of the pile body.

[0017] Furthermore, a hexagonal groove is provided on each side of the two pile heads that are away from each other.

[0018] Through the above solution and the above arrangement, it is convenient for the user to use a tool to rotate the pile head, thereby achieving rapid installation and removal of the pile head.

[0019] Furthermore, the outer surface of the pile body is treated with anti-slip treatment.

[0020] Through the above scheme and the above arrangement, the friction between the pile body and the soil can be increased, the pull-out resistance of the pile body can be improved, and the stability of the pile body in the soil can be ensured.

[0021] Furthermore, the pile body is configured as a variable-section cylindrical shape, and the pile body gradually increases in size from one end to the other, forming a tapered appearance.

[0022] Through the above scheme and the above arrangement, the stress state of the pile body in the soil can be optimized, and the bearing capacity and stability of the pile body can be improved.

[0023] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

It is particularly suitable for soft soil foundations or occasions that need to withstand large vertical loads, enhancing the safety and stability of the project. The internally arranged steel cage includes multiple steel strands and annular steel reinforcing wires arranged at equal distances, ensuring the uniform distribution of the steel cage inside the pile body. This design not only improves the bending, compression and shear resistance of the pile body, but also makes the pile body structure more stable and able to withstand greater external forces. The design of the pile head adopts an internal thread connection and a hexagonal groove structure, making the installation and removal of the pile head more convenient, not only improving construction efficiency, but also reducing the error rate during the installation process, ensuring the quality and progress of the project. The inner base layer is made of high-strength concrete material, and the outer base layer is set as a glass fiber reinforced polymer composite material layer, which effectively protects the pile body from external environmental erosion, such as chemical corrosion and physical wear, and increases the service life.

[0035] See also Figure 1 、 Figure 2 and Figure 3 The outer surface of the pile body 1 is provided with a group of pouring holes 9.

[0037] The working principle of the above embodiment is as follows: first, a steel cage 2 is provided inside the pile body 1 of the tubular pile, and the steel cage 2 is composed of a plurality of steel strands 201 and annular steel wires 202 arranged at equal distances in a circle.
