[0002] Plastic steel sheet piles are a new type of water conservancy material that can be used for river bank protection, waterway bank protection, hydraulic construction anti-seepage and other projects. They have strong tensile strength, compressive strength, bending strength, and strong impact resistance. Plastic steel sheet piles are made of high molecular resin polymers, which have good performance in corrosion resistance, UV resistance, corrosion resistance, weather resistance, oxidation resistance, ant resistance, frost resistance and high temperature resistance. The material composition of plastic steel sheet piles is stable, does not contain heavy metals and various plasticizers, is not affected by climate and water quality, has pollution resistance, and does not contain toxic and harmful substances. Because plastic steel sheet piles are convenient and fast to construct, occupy less space, and have no maintenance costs in the later stage, they provide a more environmentally optimized and cost-effective option for river and water environment management.

[0003] Traditional plastic steel sheet piles do not have water-permeable holes, which have good anti-seepage properties, but at the same time they also block the connectivity between groundwater and surface water, and block the replenishment and drainage relationship between groundwater and surface water. Although the existing plastic steel sheet piles with circular water-permeable holes can open up the connection between groundwater and surface water, the existing circular water-permeable hole structure is prone to pipe bursts, causing soil erosion, and seriously affecting the safety of the river.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide a water-permeable and breathable ecological sheet pile to solve the problems existing in the prior art, so that the plastic-steel sheet pile is water-permeable and breathable without causing soil erosion.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1 to 6 As shown, in this embodiment, a water-permeable and breathable ecological sheet pile is provided, including a sheet pile body 1 and a seepage hole 3. The sheet pile body 1 is provided with a plurality of seepage holes 3, and a protective cover 2 is provided on the seepage hole 3. The protective cover 2 is water-permeable and breathable. The protective cover 2 and the seepage hole 3 in this embodiment become a bridge between groundwater and surface water, making the sheet pile body 1 water-permeable and breathable, and "breathing", while the protective cover 2 also improves the tensile, compressive and bending strengths of the water-permeable and breathable plastic steel sheet pile.

[0030] As an optional solution, in this embodiment, the protective cover 2 is located on the same side of the sheet pile body 1, which has a neat appearance and is easy to process.

[0031] As an optional solution, in this embodiment, the seepage holes 3 and the protective cover 2 are arranged in a matrix or staggered on the flat side of the sheet pile body 1. The protective cover 2 and the seepage holes 3 can be arranged in a matrix, a single row, multiple rows, or rows staggered. Figures 4 to 5 As shown, it is sufficient as long as they can be evenly distributed on the flat side surface of the sheet pile body 1 according to the template.

[0032] As an optional solution, in this embodiment, the protective cover 2 is arranged above the seepage holes 3 and is arranged one-to-one with the seepage holes 3, and the protective cover 2 is provided with flow holes 4. The shape of the protective cover 2 can also be hemispherical, and then the flow holes 4 are punched.

[0033] As an optional solution, in this embodiment, the protective cover 2 is a U-shaped cover with the center line set in the horizontal direction, and the edges and corners are rounded to be more rounded, which is convenient for construction and molding. Flow holes 4 are set on both sides of the U-shaped cover, so that the flow holes 4 on the left and right sides are opened in the horizontal direction, which changes the seepage direction of the original groundwater flow (downward), thereby further preventing soil erosion caused by pipe bursts.

[0034] As an optional solution, in this embodiment, the protective cover 2, the flow hole 4 and the sheet pile body 1 are stamped into one piece without welding points, and the manufacturing process is simple and the strength is reliable.

[0035] As an optional solution, in this embodiment, the seepage hole 3 is a rectangular hole, a waist-shaped hole or an elliptical hole, and the flow hole 4 is a rectangular hole, a waist-shaped hole, an elliptical hole, a semicircular hole or a special-shaped hole. In this embodiment, the edge of the protective cover 2 is rounded to facilitate the later pile construction and contact with the water flow; the seepage hole 3 is a strip-shaped long hole that can obtain more groundwater permeable area, and two flow holes 4 are set, which also allows groundwater to pass through the ecological sheet pile more quickly. Among them, the seepage hole 3 and the flow hole 4 can be set in shape and opening area according to demand, and can also be set in shape according to process requirements. The opening area of ​​the seepage hole 3 and the flow hole 4 can be adjusted according to the actual situation of the soil particle grading. If the soil particle grading encountered is good, the opening area of ​​the seepage hole 3 and the flow hole 4 can be appropriately increased. If the soil particle grading encountered is poor, the opening density of the seepage hole 3 and the flow hole 4 can be appropriately increased, but the opening area of ​​the seepage hole 3 and the flow hole 4 needs to be reduced.

[0036] As an optional solution, the material of the sheet pile body 1 in this embodiment includes any one of plastic steel, aluminum-plastic plate, carbon fiber, and aluminum alloy, which is strong and sturdy, easy to shape, and will not rust. In this embodiment, plastic steel material is preferred, so that the sheet pile body 1 is extruded and formed by environmentally friendly polymer reinforced composite materials.

[0037] As an optional solution, in this embodiment, a plurality of vertical reinforcing ribs 5 are provided on the sheet pile body 1 to improve the tensile, compressive and bending strengths of the water-permeable and air-permeable plastic steel sheet pile.

[0038] As an optional solution, the sheet pile body 1 in this embodiment includes M-type sheet piles, F-type sheet piles, Z-type sheet piles, U-type and FH-type sheet piles. Both ends of the sheet piles of various types can be provided with a snap-on structure for connection according to conventional operations in the field, and sheet piles of special shapes can also be customized according to construction requirements. The sheet pile body 1 in this embodiment can be applied to various types of sheet piles, and it is sufficient to avoid opening holes at the snap-on locations. It is best to use flat surface punching, and attach Figure 1-Figure 3 Only a few shapes of sheet piles are listed for reference.

[0039] The water-permeable and breathable ecological sheet piles in this embodiment can effectively prevent pipe bursts from causing soil erosion; the protective cover 2 changes the direction of groundwater seepage, thereby preventing soil erosion, while improving the tensile, compressive and bending strength of the plastic-steel sheet piles; the strip-shaped seepage holes 3 can obtain more groundwater permeability area, allowing groundwater to penetrate the ecological sheet piles more quickly.

[0040] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
