Description

Technical Field

[0001] This application relates to the field of water conservancy projects, and particularly to a polymer pile and a protection structure. Background Art

[0002] Vertical piles are a type of basic material used in the construction and water conservancy industries and can be used to construct riverbank protection, foundation pit support, etc. In the prior art, vertical piles are used in combination with each other. However, when subjected to the scouring of water waves, the acting force at the combined position of the vertical piles is greater. Due to the small structural strength and low tensile strength of the vertical piles, it is difficult to improve the service life of the vertical piles. Currently, polymers are used to manufacture vertical piles to improve the tensile strength.

[0003] The cross-sectional shape of the polymer piles in the prior art can be a U-shaped structure or a circular structure, imitating the cross-section and outer surface of L-shaped steel sheet piles and wooden piles. However, in the process of manufacturing polymer piles, only the manufacturing cost is considered, and the actual structural strength is not taken into account, resulting in a general structural strength of the polymer piles, making it difficult for the polymer piles to be popularized.

[0050] The embodiments of the present application will be specifically described below with reference to the accompanying drawings.

[0051] In some embodiments of the present application, referring to Figures 1-5 As shown, a polymer pile is provided, including: a pile body 10, and a polymer material layer is coated on the outer surface of the pile body 10. By covering the surface of the pile body 10 with a polymer material layer, the wear resistance and corrosion resistance of the pile body 10 are improved, thereby enhancing the resistance of the polymer pile to the external environment. Specifically, the pile body 10 includes a main body, a hollow cavity is provided inside the main body of the pile body 10, and a support structure is provided in the cavity. By providing a support structure inside the main body of the pile body 10, the purpose of improving the structural strength of the pile body 10 is achieved.

[0052] The main body of the pile body 10 in the above embodiment is composed of a first transverse unit 110, a second transverse unit 120 and a vertical unit 140. Among them, the first transverse unit 110 and the second transverse unit 120 are arranged at intervals. At the same time, the first transverse unit 110 and the second transverse unit 120 are connected by the vertical unit 140 to form a whole, that is, the first transverse unit 110, the vertical unit 140, and the second transverse unit 120 are connected in sequence, so that the outer contour shape of the main body of the pile body 10 is in an I shape. Exemplarily, the first transverse unit 110, the second transverse unit 120 and the vertical unit 140 are formed by an integral combination method.

[0053] The first horizontal unit 110 has a first facade 111 and a second facade 112 that are oppositely arranged. The vertical unit 140 is connected to the first facade 111. A buckle 113 is provided on one side adjacent to the first facade 111, and a bayonet 114 adapted to the buckle 113 is provided on the other side adjacent to the first facade 111. In a specific embodiment, the buckles 113 and bayonets 114 on the two polymer piles are connected by snap-fitting to realize the connection of the two polymer piles.

[0054] However, the polymer material is applied to the outer surface of the pile body 10 to improve the durability of the pile body 10, and the internal structural strength of the pile body 10 still mainly depends on the outer wall of the pile body under the polymer material layer. Therefore, in this embodiment, reinforcing ribs 130 are provided at least in the upper and lower wings of the pile body 10 and in the buckle 113. When the above-mentioned polymer pile is applied to the protective structure, the upper wing part of the pile body 10 is installed on the soil-facing surface 30, and the buckles 113 and bayonets 114 are provided on the lower wing part.

[0055] Combined with this solution, during the use of the protective structure, when subjected to external force impacts (external force impacts include water flow, wind force or human factors), there is a tendency for relative displacement between the polymer piles. Since the two polymer piles are connected by the buckles 113 and bayonets 114, and the upper wing part of the pile body 10 is blocked by the soil-facing surface 30, the relative displacement of the polymer piles is restricted to maintain the integrity of the protective structure. However, this also results in relatively concentrated stresses on the buckles 113 and bayonets 114, as well as the lower wing and the upper wing part of the pile body 10 that are respectively close to the buckles 113 and bayonets 114, making them more prone to breakage.

[0056] In this application, reinforcing ribs 130 are provided in the areas of stress concentration on the polymer pile to improve the structural strength of the stress concentration areas on the polymer pile, thereby avoiding over-fatigue breakage.

[0057] Compared with the existing polymer material piles, using reinforcing ribs 130 to reinforce the areas of stress concentration on the polymer pile can appropriately reduce the use of polymer materials on the premise of improving the strength of the polymer pile structure, thereby reducing the manufacturing cost and facilitating the popularization of the above-mentioned polymer piles and the protective structures composed of the above-mentioned polymer piles. Exemplarily, the material of the reinforcing ribs 130 can be any one of asbestos fiber, metal fiber, ceramic fiber, single crystal, and nylon fiber.

[0058] It can be understood that the upper and lower wings of the pile body 10 are respectively the parts where the second transverse unit 120 and the first transverse unit 110 protrude from the vertical unit 140. The widths of the first transverse unit 110 and the second transverse unit 120 are both greater than the width of the vertical unit 140, and the width of the first transverse unit 110 is greater than the width of the second transverse unit 120. Among them, the width of the first transverse unit 110 can be understood as the maximum interception width of the polymer pile. The width directions of the second transverse unit 120 and the vertical unit 140 are arranged parallel to the width direction of the first transverse unit 110. Specifically, for the upper and lower wings of the pile body 10, the parts where the second transverse unit 120 and the first transverse unit 110 protrude from the outer wall surface of the vertical unit 140 are the upper wing blocks 120 and the lower wing blocks. The outer wall surface of the vertical unit 140 can be the two reference planes serving as the measurement reference for the width of the vertical unit 140.

[0059] Furthermore, the present application also provides a protection structure, including at least two polymer piles in the above examples. Multiple polymer piles are arranged in a straight line direction. Adjacent two polymer piles are clamped and connected through the cooperation of a buckle 113 and a bayonet 114, and the second facades 112 of multiple polymer piles are arranged on the same side. After the protection structure is installed on the river bank, the second facade 112 faces the water-facing surface 20. In contrast, the first facade 112 faces the soil-facing surface 30, and the second transverse unit 120 is installed in the soil-facing surface 30.

[0060] It can be understood that the above polymer piles are not limited to being used for river bank protection, but can also be used in common construction projects such as foundation pit support and underground anti-seepage.

[0061] Even further, the first transverse unit 110 has a first cavity 1101 inside, the second transverse unit 120 has a second cavity 1201 inside, and the vertical unit 140 has a communication cavity 1401 inside. The first cavity 1101, the communication cavity 1401, and the second cavity 1201 are sequentially connected to form an I-shaped cavity. Specifically in this solution, a hollow cavity is formed inside the main body of the pile body 10. The contour of the cavity is concentric with the outer contour of the pile body 10, so that the cross-sectional shape of the main body of the pile body 10 is annular, and the reinforcing ribs 130 are embedded in the thin walls of the upper and lower wings of the pile body 10.

[0062] More specifically, the first transverse unit 110 and the second transverse unit 120 form two opposite lower wing blocks with the two side faces, and the buckle 113 and the bayonet 114 are respectively arranged on the two lower wing blocks. The reinforcing ribs 130 are arranged on one side of the lower wing block close to the side face, and the reinforcing ribs 130 located inside the lower wing block extend into the buckle 113. Among them, the side face of the first transverse unit 110 is the plane where the measurement reference for the maximum interception width of the first transverse unit 110 is located.

[0063] Furthermore, the first cavity 1101 communicates with the bayonet 114. A hook portion is provided on one side surface of the main body of the pile body 10. The hook portion includes a first hook portion 1111 and a second hook portion 1121. The first hook portion 1111 and the second hook portion 1121 are arranged with a gap therebetween, and the first hook portion 1111 and the second hook portion 1121 are symmetrically arranged. In this solution, the wall surface on one side surface bends towards the inside of the first cavity 1101 to form the hook portion, so that the hook portion extends towards the first cavity 1101. That is, both the first hook portion 1111 and the second hook portion 1121 extend into the first cavity 1101, and the gap between the first hook portion 1111 and the second hook portion 1121 serves as the bayonet 114.

[0064] In addition, the buckle 113 includes a fixed cap portion 1131 and a root portion 1132. The fixed cap portion 1131 is connected to the side surface of the main body of the pile body 10 through the root portion 1132. The fixed cap portion 1131, the root portion 1132 and the side surface form two symmetrically arranged receiving grooves, and the hook portion is received in the receiving grooves. The fixed cap portion 1131 extends into the first cavity 1101, while the root portion 1132 is retained in the gap between the first hook portion 1111 and the second hook portion 1121.

[0065] In a specific embodiment, as shown in Figure 6 The shape of the fixed cap portion 1131 is semi-circular, and the width of the fixed cap portion 1131 is greater than the distance between the first hook portion 1111 and the second hook portion 1121. When the fixed cap portion 1131 extends into the first cavity 1101, the first hook portion 1111 and the second hook portion 1121 abut against the fixed cap portion 1131 to restrict the fixed cap portion 1131 from withdrawing from the first cavity 1101, so as to ensure the connection stability of the two polymer piles.

[0066] In the above embodiment, the root portion 1132 is in interference fit or transition fit with the bayonet 114 to reduce the gap between the root portion 1132 and the hook portion, thereby improving the sealing performance at the connection between the root portion and the bayonet 114. When multiple polymer piles are spliced into a protective structure and installed on the river bank, it is difficult for river water to pass between the two polymer piles, thus playing a role in water stopping.

[0067] It should be noted that the shape of the fixed cap portion 1131 includes but is not limited to semi-circular. The fixed cap portion 1131 can also be of special shape, and the fixed cap portion 1131 can be connected to the first hook portion 1111 and the second hook portion 112 by means of mortise and tenon. For example, the fixed cap portion has an arc-shaped protrusion to match the concave space formed at the bending portions of the first hook portion 1111 and the second hook portion 1121, so as to improve the connection stability of the two polymer piles by increasing the contact area. The first hook portion 1111, the second hook portion 1121 and the fixed cap portion are connected by means of mortise and tenon to realize the connection of the two I-shaped piles.

[0068] In some embodiments of the present application, a support structure is disposed inside the cavity of the main body of the pile 10 to improve the structural strength of the polymer pile. In some specific embodiments, a filling layer unit 150 is provided inside the cavity of the main body of the pile 10, and the inside of the filling layer unit 150 is in a grid shape. Exemplarily, the filling layer unit 150 has a honeycomb structure. The filling layer unit 150 is filled inside the cavity of the main body of the pile 10, and the filling layer unit 150 contacts the inner wall surfaces of the other cavities except where the bayonet 114 is provided. The filling layer unit 150 plays a supporting role to improve the strength of the polymer pile, and the grid design can minimize the use of manufacturing materials.

[0069] In some other specific embodiments, a support plate 115 is provided inside the cavity. By means of the support plate 115 provided inside the cavity, the structural strength of the polymer pile frame is improved. Refer to Figures 7-9 As shown, the specific layout mode of the support plate 115 inside the cavity includes:

[0070] At least two support plates 115 are provided inside the first cavity 1101 of the first lateral unit 110. Both support plates 115 are connected to the inner wall surfaces where the first vertical surface 111 and the second vertical surface 112 are located, and the support plates 115 are respectively disposed close to the buckle 113 and the bayonet 114. The first cavity 1101 is separated into a first sub-cavity 1102 and a second sub-cavity 1103 located on both sides via the two support plates 115. Among them, the first sub-cavity 1102 is disposed close to the buckle 113, and the second sub-cavity 1103 is disposed close to the bayonet 114, that is, the bayonet 114 communicates with the second sub-cavity 1103. In addition, a support plate 115 is also provided inside the communication cavity 1401 of the vertical unit 140, and the support plate 115 is connected to the inner wall surfaces of the two opposite walls of the vertical unit 140.

[0071] Furthermore, the arrangement position of the support plate 115 inside the first cavity 1101 is adapted to the reinforcing rib 130 disposed inside the first lateral unit 110. Specifically, the reinforcing ribs 130 inside the first lateral unit 110 are distributed on both side surfaces and in partial positions of the first vertical surface 111 and the second vertical surface 112. In this solution, the reinforcing ribs 130 on the first vertical surface 111 and the second vertical surface 112 extend from the corresponding side surfaces to be flush with the adjacent support plate 115, and the reinforcing ribs 130 and the support plate 115 are used to ensure the strength of the structures of the first sub-cavity 1102 and the second sub-cavity 1103.

[0072] The surface of the second vertical surface 112 is arc-shaped, and decorative stripes are provided on the surface of the second vertical surface 112. The surface of the second vertical surface 112 is processed into an arc shape, so that the polymer pile can simulate a wooden pile in a river revetment, which can not only improve the ecology of the river and the lake surface, but also improve the aesthetic degree of the protection structure.

[0073] In some embodiments of the present application, a plurality of decorative stripe grooves 1122 are further formed on the surface of the second facade 112. The plurality of stripe grooves 1122 are evenly arranged along the arc on the second facade 112, and the stripe grooves 1122 extend through the two opposite end faces of the polymer pile along the length direction of the polymer pile. Wherein, the length direction of the polymer pile is the vertical direction after the polymer pile is installed, that is, the direction perpendicular to the horizontal plane.

[0074] It can be understood that the decorative stripes include but are not limited to arranging the stripe grooves 1122. The second facade 112 can also form a wood-like texture or other common decorative textures through wood grain imitation treatment as decorative stripes.

[0075] The above embodiments are used to further illustrate the present application, but do not limit the present application to these specific embodiments. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be understood to be within the protection scope of the present application.
