Description

Technical Field

[0001] The invention relates to the technical field of ecological environmental protection, and in particular to an ecological plastic-steel sheet pile. Background Art

[0002] Plastic steel sheet pile is a new type of water conservancy material, which can be used for river bank protection, waterway bank protection, hydraulic construction anti-seepage and other projects. Plastic steel sheet pile is a high molecular resin polymer, which performs well in corrosion resistance, UV resistance, corrosion resistance, weather resistance, oxidation resistance, ant resistance, frost resistance and high temperature resistance. Plastic steel sheet pile has strong tensile strength, compressive strength, bending strength, and strong impact resistance. The material composition of plastic steel sheet pile is stable, does not contain heavy metal substances and various plasticizers, is not affected by climate and water quality, has anti-pollution properties, and does not contain toxic and harmful substances. The construction is convenient and fast, takes up little space, and has no maintenance cost in the later stage. It provides an economical and environmentally more optimized option for river and water environment management.

[0003] Traditional plastic steel sheet piles have no water-permeable holes or circular water-permeable holes. When no water-permeable holes are set, plastic steel sheet piles have better 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; when circular water-permeable holes are set, the connection between groundwater and surface water can be opened, but it is easy to cause pipe bursts, causing soil erosion and seriously affecting the safety of the river.

DETAILED DESCRIPTION

[0027] 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.

[0028] The purpose of the present invention is to provide an ecological plastic-steel sheet pile to solve the problems existing in the above-mentioned prior art, to ensure water permeability and air permeability, and to prevent soil erosion.

[0029] 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.

[0030] like Figures 1 to 7 As shown, this embodiment provides an ecological plastic steel sheet pile, including: a main body 1 and a filter layer 3, one side of the main body 1 is provided with a plurality of fish scale-shaped water-permeable and air-permeable hole structures 2, the fish scale-shaped water-permeable and air-permeable hole structures 2 can make the two sides of the main body 1 connected, and the filter layer 3 is located on the other side of the main body 1. One side of the ecological plastic steel sheet pile is soil, and the other side of the ecological plastic steel sheet pile is the water-facing side. The water in the soil can be discharged into the water-facing side through the fish scale-shaped water-permeable and air-permeable hole structure 2. The fish scale-shaped water-permeable and air-permeable hole structure 2 is used in conjunction with the filter layer 3 to filter soil samples and prevent soil and water loss.

[0031] Specifically, in the present embodiment, the fish-scale-shaped water-permeable and air-permeable pore structure 2 is integrally formed with the main body 1 by stamping, a cavity is formed inside the fish-scale-shaped water-permeable and air-permeable pore structure 2, an opening 4 is formed between the upper end of the fish-scale-shaped water-permeable and air-permeable pore structure 2 and the main body 1, and a through hole is provided at the corresponding position of the main body 1 and the fish-scale-shaped water-permeable and air-permeable pore structure 2, and the opening 4, the cavity and the through hole are connected in sequence. In the present embodiment, the opening 4 is arranged upward, and the particles in the soil side need to overcome gravity to pass through the opening 4. Therefore, the particles in the soil side are not easy to flow out from the soil side to the water-facing side, thereby preventing soil and water loss. The fish-scale-shaped water-permeable and air-permeable pores in the present embodiment can obtain a large groundwater permeable area, so that groundwater can pass through the ecological plastic steel sheet pile more quickly.

[0032] In this embodiment, the fish scale-shaped water-permeable and air-permeable pore structure 2 is a curved surface protruding toward one side of the main body 1, that is, the fish scale-shaped water-permeable and air-permeable pore structure 2 protrudes toward the side away from the soil, preferably a quarter sphere or a quarter ellipsoid, that is, the inner surface and the outer surface of the fish scale-shaped water-permeable and air-permeable pore structure 2 are both quarter spheres or quarter ellipsoids. When water contacts the scale-shaped water-permeable and air-permeable pore structure, the water flows along the arc surface, and the flow condition is good. In addition, the fish scale-shaped water-permeable and air-permeable pore structure 2 is a curved surface, which improves the strength compared with directly opening holes on the main body 1. The height, outer curved surface, and opening degree of the top opening 4 of the fish scale-shaped water-permeable and air-permeable pore structure 2 can be adjusted according to the actual situation of the soil particle gradation.

[0033] In this embodiment, the shape of the through hole is the same as the shape of the projection of the fish-scale water-permeable and air-permeable pore structure 2 on the main body 1. For example, when the outer wall of the fish-scale water-permeable and air-permeable pore structure 2 and the inner wall of the fish-scale water-permeable and air-permeable pore structure 2 are both quarter-spherical surfaces, the shape of the through hole is semicircular. When the outer wall of the fish-scale water-permeable and air-permeable pore structure 2 and the inner wall of the fish-scale water-permeable and air-permeable pore structure 2 are both quarter-ellipsoidal surfaces, the shape of the through hole is semi-elliptical, and a semi-ellipse is half of an ellipse.

[0034] In this embodiment, the position of the filter layer 3 corresponds to the position of the fish-scale-shaped water-permeable and breathable pore structure 2; a first clamping structure 5 and a second clamping structure 6 are provided on one side of the main body 1, and the main body 1, the first clamping structure 5 and the second clamping structure 6 form a groove for placing the filter layer 3. The filter layer 3 is arranged on one side of the main body 1 through the first clamping structure 5 and the second clamping structure 6. A protrusion is provided at the lower end of the main body 1 and the corresponding position of the filter layer 3 to avoid changes in the position of the filter layer 3 when the ecological plastic steel plate is inserted.

[0035] In this embodiment, the filter layer 3 is one or more of geomembrane, non-woven fabric, geotextile, geosynthetics, geotechnical special materials, composite geomembrane, non-woven geotextile, and woven geotextile. The material of the filter layer 3 includes but is not limited to the above materials.

[0036] In this embodiment, a plurality of groups of fish-scale water-permeable and air-permeable hole structures 2 are provided on the main body 1, each group of fish-scale water-permeable and air-permeable hole structures 2 includes at least one column of fish-scale water-permeable and air-permeable hole structures 2, each column of fish-scale water-permeable and air-permeable hole structures 2 includes a plurality of fish-scale water-permeable and air-permeable hole structures 2, and the plurality of fish-scale water-permeable and air-permeable hole structures 2 extend along the height direction of the main body 1. The fish-scale water-permeable and air-permeable hole structures 2 in adjacent rows in each group of fish-scale water-permeable and air-permeable hole structures 2 are arranged one by one or staggered.

[0037] In this embodiment, the cross-sectional shape of the main body 1 is M-shaped, F-shaped or Z-shaped, and the cross-sectional shape of the main body 1 includes but is not limited to the above-mentioned types. A number of parallel reinforcing rib structures 7 are arranged on the main body 1, and each group of fish-scale-shaped water-permeable and air-permeable pore structures 2 is arranged between adjacent reinforcing rib structures 7; a first connecting structure 8 is arranged at one end of the main body 1, and a second connecting structure 9 is arranged at the other end of the main body 1. The first connecting structure 8 and the second connecting structure 9 are matched to achieve the connection of adjacent ecological plastic steel sheet piles. The cross-sectional shape of the first connecting structure 8 is C-shaped, and the cross-sectional shape of the second connecting structure 9 is H-shaped or T-shaped, or the cross-sectional shape of the first connecting structure 8 is H-shaped or T-shaped, and the cross-sectional shape of the second connecting structure 9 is C-shaped.

[0038] The ecological plastic steel sheet piles of this embodiment solve the problem that the traditional ecological plastic steel sheet piles are impermeable and breathable, and the problem that the circular permeable and breathable holes reduce the rigidity of the sheet piles and are prone to pipe bursts and soil erosion.

[0039] The ecological plastic steel sheet pile of this embodiment can connect groundwater (soil side) with surface water (water-facing side), and at the same time improve the tensile, compressive and bending strength of the plastic steel sheet pile. The fish scale-shaped water-permeable and air-permeable openings 4 on the ecological plastic steel sheet pile are all facing upward, changing the direction of groundwater seepage, thereby preventing soil and water loss; the nested filter layer 3 can effectively prevent pipe bursts from causing soil and water loss.

[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.
