Description

Technical Field

[0001] This utility model relates to the technical field of retaining walls or waterproof walls in water conservancy projects, and in particular to ecological sheet piles and sheet pile walls. Background Technology

[0002] Sheet piles, as an engineering component that combines soil retention, seepage prevention, and erosion resistance, have been widely used in riverbank protection, slope reinforcement, and other engineering projects. Their core design logic involves splicing single piles to form a continuous vertical retaining structure, relying on material strength and structural form to resist lateral earth pressure, water flow impact, or seepage, thus ensuring the stability of the engineering area. Currently, sheet pile structures focus on improving protective and load-bearing performance, but have limitations in ecological function, exhibiting weak ecological connectivity and poor habitat support capacity; in other words, sheet piles sever the ecological connection between water and soil. Utility Model Content

[0003] This utility model aims to overcome the problem of poor synergy between structural stability and ecological function of sheet piles in the prior art, and provides ecological sheet piles and sheet pile walls.

[0004] To achieve the above objectives, the present invention provides an ecological sheet pile, comprising a belly, wings, a groove, ribs, and a planting trough. The wings are connected to both sides of the belly, and the wings and the belly enclose the groove. At least one rib is provided in the groove, and the planting trough penetrates the belly and the rib.

[0005] In one embodiment, the planting trough is set at an angle to the length direction of the abdomen.

[0006] In one embodiment, the angle is less than or equal to 90°.

[0007] In one embodiment, the planting trough includes a first opening and a second opening, which are located at opposite ends of the planting trough. The first opening is opened on the upper surface of the rib, and the second opening is opened on the back of the abdomen. The first opening and the second opening are of different sizes.

[0008] In one embodiment, the first opening is formed on the upper surface of the rib near the edge of the abdomen.

[0009] In one embodiment, the angle between the upper surface of the rib and the upper abdomen is greater than or equal to 90° and less than or equal to 100°.

[0010] In one embodiment, the angle between the upper surface of the rib and the upper part of the abdomen is 90°.

[0011] In one embodiment, the thickness of the rib is less than or equal to the depth of the groove.

[0012] In one embodiment, the rib is provided with reinforcing ribs.

[0013] In one embodiment, the ecological sheet pile further includes a bottom, which is located at the bottom end of the ecological sheet pile, and the width of the upper and lower sides of the bottom is different, forming a pointed shape.

[0014] In one embodiment, the ecological sheet pile further includes a top, which is disposed in the groove and connected to the end of the belly.

[0015] In one embodiment, the ecological sheet pile is a U-shaped pile.

[0016] This utility model also provides a sheet pile wall, comprising a plurality of ecological sheet piles as described above, wherein adjacent ecological sheet piles are connected to form the sheet pile wall.

[0017] In summary, this utility model provides ecological sheet piles and sheet pile walls. By setting the ribs between the belly and the wings, and by creating vegetation trenches at an angle on the ribs and belly, this utility model provides space for plant cultivation, animal reproduction, and soil and water exchange. The angled trenches also promote water exchange efficiency and optimize the ecological function of the sheet piles.

[0026] To make the objectives and technical solutions of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] Example 1 This utility model discloses an ecological sheet pile, wherein the ecological sheet pile is provided with a steel cage to enhance the structural strength and is integrally formed by concrete casting. Figure 1 This is a schematic diagram of the sheet pile in this utility model, as shown. Figure 1 As shown, the ecological sheet pile includes a sheet pile body 1, which includes a belly 11, wings 12, and flanges 13. The wings 12 extend outwards from both sides of the belly 11, and the ends of the wings 12 extend outwards to form the flanges 13. Preferably, the extension direction of the wings 12 is at an angle α to the belly 11, where α is less than 180°; the extension direction of the flanges 13 is parallel to the belly 11. The cross-section of the ecological sheet pile is a U-shape formed by the belly 11, wings 12, and flanges 13. In other embodiments, to adapt to different installation environments, the cross-section of the sheet pile body 1 can also be elliptical, polygonal, irregular, or other shapes.

[0028] The flange 13 has a connecting portion 131 at its end, which is used to stably connect adjacent ecological sheet piles. When two adjacent ecological sheet piles are installed, the structures of the adjacent connecting portions 131 match each other. The connecting portion 131 can be a mortise and tenon joint structure to achieve rapid splicing and installation. The shape of the mortise and tenon joint structure includes, but is not limited to, a circle, a square, a polygon, an irregular shape, or other shapes.

[0029] The wing 12 and the belly 11 enclose a groove 14, and at least one rib 2 is provided at intervals along the length direction within the groove 14. The thickness L of the rib 2 is less than or equal to the depth H of the groove 14 (see...). Figure 2 The groove 14 is U-shaped; in other embodiments, the groove 14 can also be arc-shaped, irregularly shaped, or other shapes. The rib 2 serves a supporting function, effectively distributing the load on the sheet pile body 1, constraining the bending and shear deformation of the sheet pile body 1, and improving the bending resistance and stability of the structure. The rib 2 is installed within 1 / 2 of the pile length from the pile top. The rib 2 is provided with reinforcing ribs to ensure its load-bearing capacity, structural safety, durability, and improve the reliability of the ecological sheet pile.

[0030] The rib 2 is triangular prism-shaped, with its upper surface 21 and lower surface 22 intersecting. The angle between the upper surface 21 of the rib 2 and its upper part, the abdomen 11, is greater than or equal to 90° and less than or equal to 100°. Preferably, the lower surface 22 of the rib 2 is inclined to the abdomen 11, and the upper surface 21 of the rib 2 is perpendicular to the abdomen 11. This design facilitates demolding of the rib 2 and allows it to temporarily serve as an embedded ladder during construction or maintenance. The upper surface 21 of the rib 2 serves as the stepping surface of the ladder, eliminating the need for additional ladder members. This not only achieves synergistic optimization of structure and space, improving the adaptability of the ecological sheet pile in narrow working conditions, but also simplifies the overall structure and saves materials. Simultaneously, the inclined arrangement of the lower surface 22 of the rib 2 provides load dispersion for the force generated by stepping, avoiding stress concentration.

[0031] Combination Figure 2 and Figure 3 It is understood that the ecological sheet pile also includes a vegetation trough 3, which penetrates the abdomen 11 and the rib 2. The vegetation trough 3 provides space for plant planting, animal reproduction, and water and soil exchange. Preferably, the vegetation trough 3 is inclined, and the direction of the vegetation trough 3 is set at an angle β with the length direction of the abdomen 11, where the angle β is less than 90°. The inclined design of the vegetation trough 3 guides water to infiltrate and circulate obliquely, improving water exchange efficiency and contributing to water self-purification and soil moisture retention; moreover, the inclined angle facilitates processing and demolding, improving processing efficiency.

[0032] The planting trough 3 includes a first opening 31 and a second opening 32, which are located at opposite ends of the planting trough 3. The first opening 31 is located at the end of the planting trough 3 closer to the rib 2, and the second opening 32 is located at the end of the planting trough 3 closer to the abdomen 11. Further, the first opening 31 is located on the upper surface 21 of the rib 2, and the second opening 32 is located on the back of the abdomen 11. The first opening 31 and the second opening 32 have different heights, meaning the first opening 31 is higher than the second opening 32, and vice versa. When the first opening 31 is higher than the second opening 32, and the first opening 31 is a water inlet while the second opening 32 is a soil inlet, the ecological sheet pile is suitable for water replenishment and soil hydration or slope protection for loose soil. The vegetation trough 3 uses gravity to guide water from the higher water-adjacent side to the lower soil-adjacent side, actively replenishing soil moisture, preventing soil backflow, ensuring that external water bodies are not polluted by soil, and effectively mitigating water flow impact and maintaining soil structure. When the first opening 31 is higher than the second opening 32, and the first opening 31 is a soil inlet while the second opening 32 is a water inlet, the outlet water is higher than the inlet water, which helps prevent water flow from eroding and carrying away the soil behind the wall, effectively controlling soil erosion and providing habitat for amphibian breeding. When the position of the second opening 32 is higher than the position of the first opening 31, and the first opening 31 is a water outlet and the second opening 32 is a soil outlet, the ecological sheet pile is suitable for situations where the soil is flooded or the soil is soaked by backflow of water. The vegetation trough 3 uses gravity to guide the water from the higher soil side to the lower water side, which can quickly drain the water in the soil behind the pile, prevent waterlogging and protect the vegetation; and prevent backflow of external water and control soil moisture.

[0033] The rib 2 can be used to compensate for the structural performance loss caused by the planting trench 3, disperse stress concentration at the planting trench 3, and prevent cracking or breakage. Furthermore, the rib 2 is equipped with reinforcing ribs, which effectively compensate for the stiffness loss of the sheet pile caused by the planting trench 3, reduce lateral deformation, enhance force transmission capacity, and ensure the continuity of the sheet pile's load. The rib 2 and the planting trench 3 work together to achieve a balance between the safety and ecological requirements of the ecological sheet pile structure.

[0034] Furthermore, the sizes of the first opening 31 and the second opening 32 are not equal, thereby achieving flow difference control and balancing the inlet and outlet water efficiency.

[0035] Preferably, the first opening 31 is located on the upper surface 21 of the rib 2 near the edge of the abdomen 11 to facilitate water and soil exchange and reduce dead corners for accumulation.

[0036] The first opening 31 and the second opening 32 can be square holes, trapezoidal holes, circular holes, or other shapes.

[0037] Example 2 In this embodiment, as Figure 4 As shown, each rib 2 is provided with at least two planting troughs 3. The number of planting troughs 3 can be set according to different engineering scenarios.

[0038] Example 3 In another embodiment, such as Figure 5 As shown, the ecological sheet pile also includes a top 4, which is disposed in the groove 14 and connected to the end of the web 11. The top 4 is used to bear and transmit construction loads. Preferably, the lower end of the top 4 is provided with an inclined surface 41, which is connected to the first opening 31.

[0039] Example 4 In another embodiment, such as Figure 6 As shown, the ecological sheet pile also includes a bottom 5, which is located at the bottom end of the sheet pile body 1. The width of the upper and lower sides of the bottom 5 can be equal or unequal. When the width of the upper and lower sides of the bottom 5 is unequal, the bottom 5 forms a pointed shape, which facilitates embedding it into the ground during construction.

[0040] This utility model also provides a sheet pile wall, which includes a plurality of ecological sheet piles as described above, and adjacent ecological sheet piles are connected by a connecting part 131.

[0041] In summary, this utility model provides ecological sheet piles and sheet pile walls. By setting the ribs 2 between the belly portion 11 and the wing portion 12, and by obliquely opening the vegetation trenches 3 on the ribs 2 and the belly portion 11, this utility model provides space for plant cultivation, animal reproduction, and soil and water exchange. Furthermore, the oblique trenches promote water exchange efficiency and optimize the ecological function of the sheet piles. Simultaneously, the upper surface 21 of the ribs 2 is perpendicular to the belly portion 11, allowing the ribs 2 to temporarily serve as embedded ladders during construction or maintenance, improving the utilization efficiency of the sheet pile structure and expanding its applicable working conditions.
