Description

Technical Field

[0001] This invention relates to the field of plastic steel sheet pile technology, specifically a high-strength, fracture-resistant plastic steel sheet pile. Background Technology

[0002] Plastic steel sheet piles are a new type of reinforced composite material, which is formed by one-time extrusion in a special way. The appearance of the sheet pile is designed according to the basic physical principle, adopts a cross-sectional design with large moment of inertia, and is equipped with multi-directional convex and concave connectors to form a new type of continuous high-strength and high lateral bending resistance retaining structure.

[0003] Plastic steel sheet piles need to be buried in the soil during use. Existing plastic steel sheet piles are trapezoidal in shape so that multiple plastic steel sheet piles can be combined together. When plastic steel sheet piles are impacted, the plastic steel sheet piles outside the soil are prone to cracks or breakage after the impact, which reduces the service life of the plastic steel sheet piles. Summary of the Invention

[0004] The purpose of this invention is to provide a high-strength, fracture-resistant plastic steel sheet pile to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a high-strength, fracture-resistant plastic-steel sheet pile, comprising the plastic-steel sheet pile and further comprising:

The surface of the sliding frame is provided with two triangular frames, which are located at the ends of the positioning frame. The cylindrical rod passes through the positioning frame and extends to the outer end of the positioning frame.

[0011] Furthermore, the strength component includes a support rod, which is fixedly connected to the positioning frame.

A sliding block is fixedly connected to the inner wall of the plastic steel sheet pile, and a strength plate is fixedly connected to the surface of the slider. An elastic semi-circular frame is hinged to the surface of the strength plate.

[0012] A trapezoidal plate is fixedly connected to the end of the elastic semicircular frame away from the strength plate, and a recessed inclined plate is fixedly connected to the surface of the positioning frame.

[0013] Furthermore, the slider is slidably connected to the inner wall of the groove block, the strength plate is in contact with the inner wall of the plastic steel sheet pile, and there are two concave inclined plates. The two concave inclined plates are symmetrically arranged with the positioning frame as the center. The support rod is located at the end of the two concave inclined plates that are close to each other, and the trapezoidal plate is located on the lower surface of the strength plate.

[0014] Furthermore, the anti-compression component includes a limiting frame, which is fixedly connected to the inner wall of the plastic steel sheet pile. An elastic rod is sleeved on the inner wall of the limiting frame. The end of the elastic rod away from the limiting frame is hinged to an inclined rod. A movable frame is hinged to the surface of the inclined rod. A force-bearing frame is fixedly connected to the end of the movable frame away from the inclined rod. A transmission plate is fixedly connected to the surface of the force-bearing frame.

[0015] The surface of the force-bearing frame is provided with four transmission plates, the end of the inclined rod away from the pressure plate is hinged to the surface of the support rod, and the end of the force-bearing frame near the movable frame is provided with a through hole.

[0016] Furthermore, there are two inclined rods, which are symmetrically arranged around the support rod. The inclined rods pass through the concave inclined plate and extend to the outer end of the concave inclined plate.

[0017] Furthermore, the inclined rod is located at the center of the surface of the support rod, the inclined rod is located at the end of the support rod away from the elastic tripod, and the elastic rod is located at the center of the interior of the limiting frame.

[0018] Furthermore, the fixing component includes a fixing rod, which is fixedly connected to the end of the push frame. A circular hole rod is fixedly connected to the end of the fixing rod, and an elastic conical rod is slidably connected to the inner wall of the circular hole rod. An elastic sheet is hinged to the surface of the fixing rod, and the end of the elastic sheet away from the fixing rod is fixedly connected to the surface of the positioning frame.

[0019] The surface of the elastic sheet is fixedly connected to a push plate, and there are two push plates, which are symmetrically arranged with the positioning frame as the center.

[0020] Furthermore, the end of the round rod passes through the cylindrical frame and extends to the outer end of the cylindrical frame, the end of the fixed rod passes through the push frame and extends to the outer end of the push frame, and the elastic conical rod contacts the surface of the slide plate.

[0021] The present invention has the following beneficial effects:

[0022] This invention incorporates a strength component within the plastic-coated steel sheet pile. Located at the center of the sheet pile, the soil comes into contact with the strength component when it is buried, causing deformation. This strength component compresses and fixes the sheet pile, improving its resistance to breakage during operation. A compression-resistant component also exists within the sheet pile, moving towards the upper and lower ends of the pile as the strength component moves. This compression-resistant component further enhances the strength of the sheet pile outside the soil. A fixing component moves inward through the compression of the strength component, using soil pressure to fix the strength component, further increasing the sheet pile's resistance to breakage during use.

[0023] When the lower surface of the plastic steel sheet pile is buried, the soil will come into contact with the surface of the concave inclined plate. The concave inclined plate and the positioning frame will push the cylindrical rod to one end of the plastic steel sheet pile. When the cylindrical rod moves, it will push the slide to expand on the surface of the sliding plate through the tripod. The positioning frame will move towards the inner wall of the plastic steel sheet pile through the expansion of the slide. The support rod will use the compression of the cylindrical rod to push the slider to slide inside the sliding block through the elastic tripod. When the slider slides, it will compress the inner wall of the plastic steel sheet pile through the strength plate. The compression of the strength plate will improve the fracture resistance of the plastic steel sheet pile during use.

[0024] When the support rod of this invention moves towards the inner wall of the plastic steel sheet pile, the support rod pushes the pressure plate to move through the inclined rod. The two pressure plates move towards the upper and lower ends of the plastic steel sheet pile through the support rod. The pressure of the support rod contacts the plastic steel sheet pile through the pressure plate, improving the strength of the plastic steel sheet pile outside the soil. When the plastic steel sheet pile is buried, the soil enters the interior of the force frame through the through hole and contacts the surface of the transmission plate. The soil squeezes the force frame towards the inner wall of the plastic steel sheet pile, thereby improving the stability of the pressure plate during support.

[0025] When the support rod of this invention moves into the interior of the plastic steel sheet pile, the inclined rod pushes the round rod to move through the cylindrical frame, and the pusher uses the round rod to squeeze the fixed rod to move into the interior of the plastic steel sheet pile. The elastic conical rod is squeezed and contracted into the interior of the round hole rod by the sliding plate. When the elastic conical rod separates from the surface of the sliding plate, the elastic conical rod extends into the interior of the plastic steel sheet pile and contacts the inner wall of the plastic steel sheet pile by elasticity. The compression of the elastic conical rod by the sliding plate prevents the support rod from returning to its original position and improves the fracture resistance of the plastic steel sheet pile.

[0026] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figures 1-8 As shown, the present invention is a high-strength, fracture-resistant plastic steel sheet pile, comprising a plastic steel sheet pile 1, and further comprising:

[0040] The strength component 2 includes a sliding plate 13, which is fixedly connected to the inner wall of the plastic steel sheet pile 1. A slide frame 12 is slidably connected to the surface of the sliding plate 13, and a triangular frame 15 is sleeved on the surface of the slide frame 12. A cylindrical rod 16 is sleeved on the end of the triangular frame 15 away from the slide frame 12. This invention provides a strength component 2 inside the plastic steel sheet pile 1, located at the center of the interior of the plastic steel sheet pile 1. When the plastic steel sheet pile 1 is buried underground, the soil comes into contact with the strength component 2, causing it to deform. The strength component 2 then supports the plastic steel sheet pile 1. The sheet pile 1 is compressed and fixed to improve the fracture resistance of the plastic sheet pile 1 during operation. An anti-compression component 3 is set inside the plastic sheet pile 1. The anti-compression component 3 moves to the upper and lower ends of the plastic sheet pile 1 through the movement of the strength component 2. The anti-compression component 3 is used to improve the strength of the plastic sheet pile 1 outside the soil. The fixing component 4 moves into the plastic sheet pile 1 through the compression of the strength component 2. The strength component 2 is fixed by the pressure of the soil, which further increases the fracture resistance of the plastic sheet pile 1 during use. A positioning frame 10 is fixedly connected to the surface of the cylindrical rod 16.

[0041] The pressure-resistant component 3 includes a pressure plate 31, which is in contact with the inner wall of the plastic steel sheet pile 1. The pressure plate 31 has a single hinged diagonal bar 30 away from the plastic steel sheet pile 1.

[0042] The fixing component 4 includes a cylindrical frame 40, which is fixedly connected to the surface of the inclined rod 30. A round rod 41 is sleeved on the inner wall of the cylindrical frame 40, and a pusher 44 is sleeved on the surface of the round rod 41.

[0043] There are two slide plates 13, which are symmetrically arranged with the plastic steel sheet pile 1 as the center. Two tripods 15 are provided on the surface of the slide frame 12. The two tripods 15 are located at the ends of the positioning frame 10. The cylindrical rod 16 passes through the positioning frame 10 and extends to the outer end of the positioning frame 10.

[0044] The strength component 2 includes a support rod 17, which is fixedly connected to the positioning frame 10. An elastic triangular frame 18 is hinged to the surface of the support rod 17, and a slider 19 is hinged to the end of the elastic triangular frame 18 away from the support rod 17. A sliding block 20 is fixedly connected to the inner wall of the plastic steel sheet pile 1. When the lower surface of the plastic steel sheet pile 1 is buried, the soil will contact the surface of the concave inclined plate 11, and the concave inclined plate 11 and the positioning frame 10 will push the cylindrical rod 16 towards one end of the plastic steel sheet pile 1. During the movement, the cylindrical rod 16 moves through the triangular frame 1... 5. The slide 12 is pushed to expand on the surface of the slide plate 13. The positioning frame 10 moves towards the inner wall of the plastic steel sheet pile 1 through the expansion of the slide 12. The support rod 17 uses the compression of the cylindrical rod 16 to push the slider 19 to slide inside the slide block 20 through the elastic triangular frame 18. When the slider 19 slides, it compresses the inner wall of the plastic steel sheet pile 1 through the strength plate 23. The compression of the strength plate 23 improves the fracture resistance of the plastic steel sheet pile 1 during use. The surface of the slider 19 is fixedly connected to the strength plate 23, and the surface of the strength plate 23 is hinged to the elastic semi-circular frame 22.

[0045] A trapezoidal plate 14 is fixedly connected to the end of the elastic semicircular frame 22 away from the strength plate 23, and a recessed inclined plate 11 is fixedly connected to the surface of the positioning frame 10.

[0046] The slider 19 is slidably connected to the inner wall of the groove block 20, the strength plate 23 is in contact with the inner wall of the plastic steel sheet pile 1, there are two concave hole inclined plates 11, the two concave hole inclined plates 11 are symmetrically arranged with the positioning frame 10 as the center, the support rod 17 is located at the end of the two concave hole inclined plates 11 that are close to each other, and the trapezoidal plate 14 is located on the lower surface of the strength plate 23.

[0047] The pressure-resistant component 3 includes a limiting frame 33, which is fixedly connected to the inner wall of the plastic steel sheet pile 1. An elastic rod 32 is sleeved on the inner wall of the limiting frame 33. The end of the elastic rod 32 away from the limiting frame 33 is hinged to the inclined rod 30. A movable frame 34 is hinged to the surface of the inclined rod 30. When the support rod 17 moves toward the inner wall of the plastic steel sheet pile 1, the support rod 17 pushes the pressure plate 31 to move through the inclined rod 30. The two pressure plates 31 move toward the upper and lower ends of the plastic steel sheet pile 1 via the support rod 17. The pressure is applied through the pressure plate 31 to contact the plastic steel sheet pile 1, which increases the strength of the plastic steel sheet pile 1 outside the soil. When the plastic steel sheet pile 1 is buried, the soil enters the interior of the force frame 37 through the through hole 35 and contacts the surface of the transmission plate 36. The soil squeezes the force frame 37 to move towards the inner wall of the plastic steel sheet pile 1, thereby improving the stability of the pressure plate 31 when supporting. The end of the movable frame 34 away from the inclined bar 30 is fixedly connected to the force frame 37, and the surface of the force frame 37 is fixedly connected to the transmission plate 36.

[0048] The surface of the force-bearing frame 37 is provided with four transmission plates 36. The end of the diagonal bar 30 away from the pressure plate 31 is hinged to the surface of the support rod 17. The end of the force-bearing frame 37 near the movable frame 34 is provided with a through hole 35.

[0049] There are two inclined rods 30, which are symmetrically arranged with the support rod 17 as the center. The inclined rods 30 pass through the concave hole inclined plate 11 and extend to the outer end of the concave hole inclined plate 11.

[0050] The diagonal bar 30 is located at the center of the surface of the support rod 17, and the diagonal bar 30 is located at the end of the support rod 17 away from the elastic triangular frame 18. The elastic rod 32 is located at the center of the interior of the limiting frame 33.

[0051] The fixing component 4 includes a fixing rod 42, which is fixedly connected to the end of the pusher 44. A circular hole rod 43 is fixedly connected to the end of the fixing rod 42. An elastic conical rod 45 is slidably connected to the inner wall of the circular hole rod 43. An elastic sheet 47 is hinged to the surface of the fixing rod 42. When the support rod 17 moves into the plastic steel sheet pile 1, the inclined rod 30 pushes the circular rod 41 to move through the cylindrical frame 40. The pusher 44 uses the circular rod 41 to squeeze the fixing rod 42 to move into the plastic steel sheet pile 1. The elastic conical rod 45 is squeezed and contracted into the interior of the circular hole rod 43 by the sliding plate 13. When the elastic conical rod 45 separates from the surface of the sliding plate 13, the elastic conical rod 45 extends into the interior of the plastic steel sheet pile 1 and contacts the inner wall of the plastic steel sheet pile 1. The squeezing of the elastic conical rod 45 by the sliding plate 13 prevents the support rod 17 from resetting and improves the fracture resistance of the plastic steel sheet pile 1. The end of the elastic sheet 47 away from the fixing rod 42 is fixedly connected to the surface of the positioning frame 10.

[0052] A push plate 46 is fixedly connected to the surface of the elastic sheet 47. There are two push plates 46, which are symmetrically arranged with the positioning frame 10 as the center.

[0053] The end of the round rod 41 passes through the cylindrical frame 40 and extends to the outer end of the cylindrical frame 40, the end of the fixed rod 42 passes through the push frame 44 and extends to the outer end of the push frame 44, and the elastic conical rod 45 contacts the surface of the slide plate 13.

[0054] In use, a strength component 2 is installed inside the plastic steel sheet pile 1. The strength component 2 is located at the center of the plastic steel sheet pile 1. When the plastic steel sheet pile 1 is buried underground, the soil will come into contact with the strength component 2 and push the strength component 2 to deform. The strength component 2 compresses and fixes the plastic steel sheet pile 1, improving its fracture resistance during operation. A compression-resistant component 3 is installed inside the plastic steel sheet pile 1. The compression-resistant component 3 moves towards the upper and lower ends of the plastic steel sheet pile 1 by the movement of the strength component 2, thereby increasing the strength of the plastic steel sheet pile 1 outside the soil. The fixing component 4 moves into the plastic steel sheet pile 1 by the compression of the strength component 2. The pressure of the soil fixes the strength component 2, further increasing the fracture resistance of the plastic steel sheet pile 1 during use. When the lower surface of the plastic steel sheet pile 1 is buried, the soil will contact the surface of the concave inclined plate 11, and the concave inclined plate 11 and the positioning frame 10 will push the cylindrical rod 16 to one end of the plastic steel sheet pile 1. When the cylindrical rod 16 moves, it will push the slide 12 to expand on the surface of the slide plate 13 through the tripod 15. The positioning frame 10 will move towards the inner wall of the plastic steel sheet pile 1 through the expansion of the slide 12. The support rod 17 will use the compression of the cylindrical rod 16 to push the slider 19 to slide inside the slide block 20 through the elastic tripod 18. When the strength plate 23 compresses the inner wall of the plastic steel sheet pile 1, the compression of the strength plate 23 improves the fracture resistance of the plastic steel sheet pile 1 during use. When the support rod 17 moves towards the inner wall of the plastic steel sheet pile 1, the support rod 17 pushes the pressure plate 31 to move through the inclined rod 30. The two pressure plates 31 move towards the upper and lower ends of the plastic steel sheet pile 1 with the support rod 17. The pressure of the support rod 17 contacts the plastic steel sheet pile 1 through the pressure plate 31, improving the strength of the plastic steel sheet pile 1 outside the soil. When the plastic steel sheet pile 1 is buried, the soil enters the interior of the force frame 37 through the through hole 35 and contacts the surface of the transmission plate 36. The soil compresses the force frame 37 towards the inner wall of the plastic steel sheet pile 1. The support rod 17 moves into the plastic steel sheet pile 1, thereby improving the stability of the pressure plate 31 during support. When the support rod 17 moves into the plastic steel sheet pile 1, the inclined rod 30 pushes the round rod 41 to move through the cylindrical frame 40. The push frame 44 uses the round rod 41 to squeeze the fixed rod 42 to move into the plastic steel sheet pile 1. The elastic conical rod 45 is squeezed and contracted into the round hole rod 43 by the sliding plate 13. When the elastic conical rod 45 separates from the surface of the sliding plate 13, the elastic conical rod 45 extends into the interior of the plastic steel sheet pile 1 and contacts the inner wall of the plastic steel sheet pile 1. The sliding plate 13 squeezes the elastic conical rod 45 to prevent the support rod 17 from returning to its original position, thereby improving the fracture resistance of the plastic steel sheet pile 1.
