[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 anti-pollution properties, 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.

[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 plastic-steel 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 plastic steel sheet pile is provided, including a sheet pile body 1 and a filter layer 2. At least one filter layer 2 is detachably provided on the side of the sheet pile body 1. The sheet pile body 1 is provided with a plurality of seepage holes 5. The filter layer 2 can cover the area where the seepage holes 5 are located. The filter layer 2 is water-permeable and breathable. Among them, the seepage holes 5 are preferably provided on the side of the sheet pile body 1 close to the water source, and the filter layer 2 is provided on the other side of the sheet pile body 1; the filter layer 2 can also be directly located in the seepage hole 5.

[0030] As an optional solution, in this embodiment, a filter layer 2 is inserted into the side surface of the sheet pile body 1 through a slot 3 .

[0031] As an optional solution, the slot 3 in this embodiment is a pair of C-shaped slots, wherein the C-shaped slots are surrounded by a sheet pile body 1 and an L-shaped or straight plate, leaving the middle part of the filter layer 2 empty to maximize the utilization of the filtration area of ​​the filter layer 2, and a bottom plate 8 is provided at the bottom of the two C-shaped slots to prevent the filter layer 2 from detaching and being damaged during construction.

[0032] As an optional solution, the filter layer 2 in this embodiment includes any one of geomembrane, non-woven fabric, geotextile, geosynthetics, geotechnical special materials, composite geomembrane, non-woven geotextile and woven geotextile; the filter layer 2 is bonded to the side of the sheet pile body 1 by hot pressing, so that the filter layer 2 and the sheet pile body 1 are bonded and not separated, and the surface is flat to avoid blistering during construction. The function of the filter layer 2 in this embodiment is mainly to prevent the occurrence of pipe bursts and soil flow, so that the infiltrated water will not take away the soil in the dam body or foundation when it flows out, and the replenishment and drainage relationship between groundwater and surface water is connected. At the same time, it can effectively prevent the occurrence of pipe bursts and avoid soil erosion; wherein, the filter layer 2 can also be directly bonded to the sheet pile body 1, or connected to the sheet pile body 1 by other connection and fixing methods.

[0033] As an optional solution, in this embodiment, a plurality of protective covers 4 are provided on the sheet pile body 1. The protective covers 4 are provided above the seepage holes 5 and are arranged one by one with the seepage holes 5. The protective covers 4 are provided with flow holes 6. The protective covers 4 in this embodiment become a bridge between groundwater and surface water, and at the same time improve the tensile, compressive and bending strengths of the water-permeable and air-permeable plastic steel sheet piles; the protective covers 4 and the seepage holes 5 can be arranged in a matrix or in a staggered arrangement, and the shape of the protective covers 4 can also be hemispherical, and then the flow holes 6 are punched.

[0034] As an optional solution, in this embodiment, the protective cover 4 is a U-shaped cover and the center line is set in the horizontal direction. Flow holes 6 are set on both sides of the U-shaped cover, so that the flow holes 6 on the left and right sides are opened in the horizontal direction, which changes the seepage direction of the original groundwater flow, thereby further preventing soil erosion caused by pipe bursts.

[0035] As an optional solution, in this embodiment, the protective cover 4, the flow hole 6 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.

[0036] As an optional solution, in this embodiment, the seepage hole 5 is a rectangular hole, a waist-shaped hole or an elliptical hole, and the flow hole 6 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 4 is rounded to facilitate the later pile construction and contact with the water flow; the seepage hole 5 is a strip-shaped long hole that can obtain more groundwater permeable area, and two flow holes 6 are set, which also allows groundwater to pass through the plastic steel sheet pile more quickly. Among them, the seepage hole 5 and the flow hole 6 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 and the flow hole 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 and the flow hole can be appropriately increased. If the soil particle grading encountered is poor, the opening density of the seepage hole and the flow hole can be appropriately increased, but the opening area of ​​the seepage hole and the flow hole needs to be reduced.

[0037] As an optional solution, in this embodiment, a plurality of vertical reinforcing ribs 7 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, and special-shaped sheet piles 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 buckle. Try to use flat surface punching, and attach Figure 1-Figure 3 Only a few shapes of sheet piles are listed for reference.

[0039] The permeable and breathable ecological plastic-steel sheet piles in this embodiment have a nested filter layer 2 that can connect groundwater and surface water, and can effectively prevent pipe bursts from causing soil and water loss; the protective cover 4 changes the direction of groundwater seepage, thereby preventing soil and water loss, and at the same time improving the tensile, compressive and bending strength of the plastic-steel sheet piles; the strip-shaped seepage holes 5 can obtain more groundwater permeability area, allowing groundwater to penetrate the plastic-steel 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.
