[0036] Such as Figure 1As shown in the figure, a curved sheet pile 1 includes a pile body 11 and a connection end 12. The first surface of the pile body 11 is an arc surface, and the second surface is a flat surface. When wave and wave elimination are required, the first surface faces outward, and the arc surface serves as the water-facing surface; when water passage or flood discharge is required, the second surface faces outward, and the flat surface serves as the water-facing surface. The connection ends 12 are respectively arranged at both ends of the pile body 11 to facilitate the connection of adjacent curved sheet piles 1.

[0037] Specifically, the curved sheet pile 1 simultaneously has the performance effects of a corrugated pile and a flat pile. When used as a flat pile, that is, when the second surface serves as the water-facing surface, the first surface faces inward, increasing the flexibility of the curved sheet pile 1 and enhancing the bending and shear resistance performance.

[0038] Specifically, the first surface of the pile body 11 can be made to have a wood-like effect, and the second surface of the pile body 11 can be made to have a stone-like effect, which is used to enhance the landscape effect of the urban river channel.

[0039] As Figure 1 shown in the figure, the edge of the first surface of the pile body 11 is formed by connecting a first side 111, a second side 112, and a third side 113. The two end points of the first side 111 are respectively connected to the second side 112 and the third side 113. The first side 111, the second side 112, and the third side 113 can be arcs, and the tangents at the connection points of the second side 112 and the third side 113 with the first side 111 coincide; the edge of the second surface of the pile body 11 is set as a fourth side 114, and the fourth side 114 is a straight line.

[0040] Specifically, the first side 111 is a sector arc. Using a sector arc for the first side 111 reduces the visual heaviness of the pile body 11 compared to a semi-circular arc, making the overall appearance more harmonious, reducing costs, and at the same time, the roughness ratio of the curved sheet pile 1 is lower.

[0041] Specifically, the two end points of the second side 112 and the third side 113 are respectively connected to the end points of the first side 111 and the edge end points of the connection end 12 to protect the connection end 12.

[0042] Specifically, as Figure 2 shown in the figure, the second side 112 and the third side 113 can also be broken lines.

[0043] Furthermore, the second side 112 and the third side 113 can also be oblique lines.

[0044] The fitting surface of the connection end 12 can be the flat surface of the original end, or a first interface 121 and a second interface 122 can be respectively arranged on the original end of the connection end 12. The first interface 121 and the second interface 122 can be mutually fitting male and female tenons or abutting platforms for controlling soil leakage.

[0045] Specifically, polypropylene fibers or glass fibers can be incorporated into the first interface 121 and the second interface 122 to enhance the strength of the arc-shaped sheet pile 1.

[0046] Please refer to Figure 1 and Figure 3 Taking the cross-section of the arc-shaped sheet pile 1 as a reference, the transverse length of the first side 111 part is set as a, the longitudinal length of the first surface is set as b, the transverse length from the end point of the first side 111 to the original end point of the connection end 12 on the same side is set as c, the longitudinal length of the second side 112 part is set as d, and the transverse length between the original end points of the connection end 12 is set as L.

[0047] Specifically, the transverse length a of the first side 111 part and the transverse length c from the end point of the first side 111 to the original end point of the connection end 12 on the same side satisfy c≥1 / 2a; the longitudinal length d of the second side 112 part and the longitudinal length b of the first surface satisfy d≥1 / 2b, the transverse length a of the first side 111 part and the longitudinal length d of the second side 112 part satisfy d≤1 / 2a; the transverse length a of the first side 111 part and the longitudinal length b of the first surface satisfy a>b.

[0048] Furthermore, the transverse length L between the transverse length a of the first side 111 part and the original end point of the connection end 12 is ≥2a.

[0049] As Figure 4 shown, the arc-shaped sheet pile 1 may further include a cavity 13 and a rib plate 14. The cavity 13 is opened in the pile body 11 to reduce production costs; a plurality of rib plates 14 are installed in the cavity 13 to protect the main stress-bearing position of the arc-shaped sheet pile 1 and enhance the compressive and tensile capacities of the arc-shaped sheet pile 1.

[0050] Specifically, when the transverse length a of the first side 111 part is greater than 10 cm, the rib plate 14 is provided in the cavity 13.

[0051] Specifically, the spacing between adjacent rib plates 14 is greater than 20 cm.

[0052] The arc-shaped sheet pile 1 may further include a filler 15. The filler 15 is filled in the cavity 13. The filler 15 can be filled in sections, and concrete is poured to fill the voids to reduce the self-weight of the arc-shaped sheet pile 1.

The side edge of the inclined bracing plate 16 coincides with the first surface, and the edge of the other side is an oblique line, connecting the two end points of the second side 112 or the third side 113. The inclined bracing plate 16 protects the connection end 12 and enhances the bending and flexural strength of the arc-shaped sheet pile 1, increasing the soil retaining width.

[0054] Specifically, the included angle formed by the upper and lower surfaces of the inclined bracing plate 16 is an acute angle.

[0055] Specifically, the inclined bracing plate 16 can effectively improve the wave dissipation rate, improve the mechanical properties, and can also serve as a climbing aid when the first surface is the water-facing surface, facilitating personnel climbing operations and rescue in case of falling into the water.

[0056] Specifically, when the second side 112 is an oblique line, the inclined bracing plate 16 is not provided.

[0057] Please combine Figure 5 and Figure 6 , the arc-shaped sheet pile 1 may further include a first hole 17. The first hole 17 is opened at the top or bottom of the pile body 11. The first hole 17 is a blind hole with a depth less than 50 cm. The first hole 17 can be used as a lifting hole, a pre-embedded hole for railings, or a vegetation hole.

[0058] The arc-shaped sheet pile 1 may further include second holes 18. A plurality of the second holes 18 are opened on the first surface and the second surface of the arc-shaped sheet pile 1. The second holes 18 are symmetrically arranged, facilitating lifting and demolding and water permeability.

[0059] The arc-shaped sheet pile 1 may further include a ladder 19. The ladder 19 is arranged on the second surface of the pile body 11. The ladder 19 can be an outward convex type with a trapezoidal cross-section or an inward concave type. When the second surface is the water-facing surface, it facilitates personnel climbing operations and rescue in case of falling into the water.

[0060] As Figure 7As shown in the figure, the steel bar framework 2 is located inside the arc-shaped sheet pile 1. The steel bar framework 2 includes a first horizontal bar 21, a second horizontal bar 22, inclined bars 23 and longitudinal bars 24. The first horizontal bar 21 is located within the part of the first side 111. The second horizontal bar 22 is located within the part of the fourth side 114. The inclined bars 23 connect the first horizontal bar 21 and the second horizontal bar 22 and are located within the part of the second side 112 and the part of the third side 113. The first horizontal bar 21, the second horizontal bar 22 and the inclined bars 23 are connected to form a closed arc trapezoid. A plurality of the longitudinal bars 24 connect the two end faces in the vertical direction, and the ends of the longitudinal bars 24 are fixed on the first horizontal bar 21, the second horizontal bar 22, the inclined bars 23, and the connection points of the first horizontal bar 21, the second horizontal bar 22 and the inclined bars 23.

[0061] Specifically, the first horizontal bar 21, the second horizontal bar 22 and the inclined bars 23 are arc-shaped steel bars.

[0062] Further, the first horizontal bar 21, the second horizontal bar 22 and the inclined bars 23 are spiral stirrups.

[0063] As Figure 8 shown in the figure, when the arc-shaped sheet pile 1 is provided with the inclined rib plate 16, the steel bar framework 2 further includes a reinforcing bar 25. The reinforcing bar 25 is a broken line, one end of which is connected to the end point of the second horizontal bar 22, and the other end is fixed on the inclined bar 23 through the inclined rib plate 16. The longitudinal bar 24 is provided at the connection point of the reinforcing bar 25 and the inclined bar 23.

[0064] In summary, the arc surface of the arc-shaped sheet pile proposed by the present utility model is used for wave dissipation and wave elimination when it is the water-facing surface, and is used for water passing or flood discharge when the plane is the water-facing surface. At the same time, it takes into account the advantages and uses of corrugated piles and flat sheet piles, has good bending and shear resistance performance, and reduces the amount of steel bars used; by designing the internal cavity structure or filling structure, the production cost is reduced, and the self-weight of the arc-shaped sheet pile is reduced; rib plates are arranged in the cavity and symmetrical inclined rib plates are arranged on the two surfaces of the arc-shaped sheet pile to protect the main stress positions, and the steel bar framework is set as an arc trapezoid structure, with good stress performance and enhanced bending and folding strength of the arc-shaped sheet pile.
