Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering bank protection structure technology, and in particular to a cavity-reinforced imitation wood pile. Background Technology

[0002] In traditional water conservancy projects, wooden piles are often used for riverbank protection. Although they can extend the seepage path and reduce the seepage gradient to a certain extent, the use of wooden piles for riverbank protection has the following disadvantages: (1) Wooden piles are easily corroded by long-term immersion in river water, thus losing their protective function; (2) Termites are easily bred in the wooden piles, causing damage to the wooden piles; (3) Wood materials depend on forest resources, and the large-scale use of wooden piles can easily cause damage to the ecological environment.

[0003] Currently, some improved revetment structures have emerged in the market, such as plastic steel sheet piles, H-shaped prestressed concrete piles, and eco-bag slope protection. Among them, plastic steel sheet piles are widely used due to their advantages such as low cost, long service life, and high lateral stiffness. However, traditional plastic steel sheet piles are generally formed by connecting multiple hollow columnar bodies to ensure lateral stiffness. This type of structure faces significant defects in actual construction: due to uneven ground foundations or deviations in installation processes, slight misalignments can easily occur at the connection positions between components. As the pile length increases, the error accumulates step by step, leading to overall pile tilting and seriously affecting the verticality and stability of the structure. Especially in large-scale continuous laying scenarios, the cumulative deviation may be further amplified, even causing problems such as pile twisting and joint cracking, reducing structural strength. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a cavity-reinforced imitation wood pile, which has good shrinkage, elongation and deformation capabilities, can reduce installation errors and improve the overall structural strength.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0006] A cavity-reinforced imitation wood pile includes multiple hollow columnar bodies and connecting plates connected together, with the hollow columnar bodies and connecting plates arranged alternately. C-shaped joints and T-shaped joints are respectively provided on the hollow columnar bodies and / or connecting plates at both ends.

[0007] As a preferred embodiment, there are two hollow cylindrical bodies, which are connected together by a connecting plate. One hollow cylindrical body has a C-shaped connector on its outer side, and the other hollow cylindrical body has a T-shaped connector on its outer side.

[0008] As a preferred embodiment, the hollow column has a notch on one side, and the profiles on both sides of the notch are folded inward to form a limiting protrusion. The hollow column also has an inner connecting profile that crosses the notch, and the inner connecting profile and the limiting protrusion form a C-shaped joint.

[0009] As a preferred embodiment, the T-shaped connector includes an extension plate and an inner buckle arranged perpendicularly to each other, with the two inner buckles located on both sides of the extension plate.

[0010] As a preferred embodiment, the cross-sectional shape of the hollow columnar body is rectangular, triangular, trapezoidal, arc-shaped, circular, rhomboid, or hexagonal.

[0011] As a preferred embodiment, the connecting plate has the same cross-sectional shape as the hollow columnar body, and is open on one side to form a groove.

[0012] As a preferred embodiment, the outer surfaces of the hollow column and the connecting plate are provided with a wood-like coating texture.

[0013] As a preferred embodiment, the coating texture includes an underlayer, a texture layer, and a protective layer that are stacked and pasted together. The texture layer is a wood grain pattern, a stone grain pattern, or an abstract geometric pattern, and the protective layer is a high-strength polyethylene film.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention ensures lateral stiffness through multiple hollow columnar bodies and sets a retractable connecting plate between two adjacent hollow columnar bodies. During construction, the deformation of the connecting plate is finely adjusted to compensate for the installation error between adjacent piles, avoiding the accumulation of errors caused by traditional rigid connections. This ensures that the overall axis is aligned and prevents deviation during the construction of long-distance pile series. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] Example 1

[0032] like Figure 1 and Figure 2 As shown, a hollow reinforced imitation wood pile includes multiple hollow columnar bodies 1 and connecting plates 2 connected together, with the hollow columnar bodies 1 and connecting plates 2 alternately arranged. C-shaped joints 10 and T-shaped joints are respectively provided on the hollow columnar bodies 1 and / or connecting plates 2 at both ends. The connecting plates are more easily deformed than the hollow columnar bodies 1, which can buffer the stress caused by external loads (such as soil settlement and temperature deformation), reduce direct impact on the hollow columnar bodies 1, and lower the risk of cracking. At the same time, they can compensate for installation errors between adjacent piles, avoid the accumulation of errors caused by traditional rigid connections, and ensure overall axis alignment during long-distance pile series construction, preventing skewing. In addition, the C-shaped joints 10 and T-shaped joints at both ends can flexibly adapt to different connection angles (such as horizontal, vertical, or inclined), further offsetting the impact of local errors during construction on the overall structure.

[0033] As a further preferred embodiment: there are two hollow columnar bodies 1, and the two hollow columnar bodies 1 are connected together by a connecting plate 2. One hollow columnar body 1 has a C-shaped connector 10 on its outer side, and the other hollow columnar body 1 has a T-shaped connector on its outer side. By limiting the two hollow columnar bodies 1 and a single connecting plate 2 to form a standard unit, the long pile is divided into multiple independent and controllable short units; the overall transportation and installation are convenient, and only the connecting plates 2 between adjacent units need to be adjusted during on-site splicing, avoiding the cumulative errors in the overall transportation and installation of the long pile.

[0034] The specific structures of the C-shaped connector 10 and the T-shaped connector in this embodiment are as follows:

[0035] The hollow columnar body 1 has a notch 7 on one side, and the profiles on both sides of the notch 7 are folded inward to form a limiting ridge 6. The hollow columnar body 1 also has an inner connecting profile 5 that crosses the notch 7. The inner connecting profile 5 and the limiting ridge 6 form a C-shaped connector 10. The T-shaped connector includes an extension plate 3 and an inner buckle 4 that are arranged perpendicularly to each other. The two inner buckles 4 are located on both sides of the extension plate 3.

[0036] When C-shaped connector 10 and T-shaped connector are plugged in, there is a gap for movement. This gap allows the water channels on both sides of the imitation wood pile to be connected, and also enables lateral fine-tuning and angle deflection, thereby actively absorbing installation errors in each link and avoiding the accumulation of deviations.

[0037] In this embodiment, the hollow columnar body 1 has a trapezoidal cross-sectional shape, and the connecting plate 2 has the same cross-sectional shape as the hollow columnar body 1, with an opening on one side forming a groove. The impact strength of the open trapezoidal connecting plate is greater than or equal to 6 kJ / m. 2 The trapezoidal cross-section provides a larger lateral contact surface, which, in conjunction with the grooved structure of the connecting plate 2, enhances torsional resistance and prevents overall deflection of the pile due to local errors. The hollow columnar body also features staggered ecological holes on its sidewalls, enabling communication between the river channel and the riverbank soil while preventing soil erosion. The hollow columnar body can store soil and water, serving as a natural habitat for organisms and a source of plant nutrients, embodying the concept of ecological harmony in water management.

[0038] The outer surfaces of the hollow column 1 and the connecting plate 2 are provided with a wood-look film texture. The film texture includes a bottom layer, a texture layer, and a protective layer that are stacked and pasted together. The bottom layer is a uniform base layer with a thickness of 1-3 mm and the same material as the pile. The texture layer is prepared by 3D printing and has a height of 0.5-2 mm. The texture shape can be selected according to the surrounding environment, such as wood-look texture, stone-look texture, or abstract geometric shape. The protective layer is a high-strength polyethylene film with a thickness of 0.2-0.5 mm, which is used to protect the texture layer and enhance the surface wear resistance.

[0039] Bottom Layer: A high-adhesion material ensures a firm bond between the membrane and the substrate (hollow columnar body 1 and connecting plate 2, formed by high-temperature extrusion of PVC or synthetic polymer raw materials), preventing peeling. Textured Layer: A three-dimensional wood / stone grain pattern is created using 3D printing or heat transfer technology, closely resembling the feel and visual effect of natural materials. Protective Layer: A high-strength polyethylene film provides UV resistance (weather resistance), scratch resistance (abrasion resistance), and stain resistance, extending its service life. The wood-look membrane texture can be selected to coordinate with the surrounding environment, ensuring harmony between the revetment and its surroundings, showcasing the regional characteristics.

[0040] Through the above technical solution, this imitation wood pile can maintain high straightness and structural stability during construction in complex terrain, completely improving the deviation problem caused by cumulative errors in traditional solutions. Moreover, its overall shape is closer to the natural ecology, with good ecological and landscape features, and can be in harmony with the surrounding environment.

[0041] Example 2

[0042] This embodiment has the same overall structure as Embodiment 1, the only difference being that the cross-sectional shape of the hollow column 1 is semi-circular, and the connecting plate 2 is arc-shaped, as shown below. Figure 3 and Figure 4 As shown.

[0043] Example 3

[0044] This embodiment has the same overall structure as Embodiment 1, the only difference being that the cross-sectional shape of the hollow column 1 is a trapezoid with rounded corners and a rounded top, and the connecting plate 2 has the same cross-sectional shape as the hollow column 1, with an opening on one side forming a groove, as shown below. Figure 5 and Figure 6 As shown.

[0045] In other embodiments, the cross-sectional shape of the hollow column 1 can also be rectangular, triangular, trapezoidal, arc-shaped, circular, rhomboid, or hexagonal.
