Abstract
Description
Technical Field
[0001] The utility model relates to the field of plastic steel sheet piles, and specifically relates to a plastic steel sheet pile with an anti-breaking structure. Background Technique
[0002] In riverbank reinforcement and protection projects, traditional concrete retaining walls are often used to enhance the stability of riverbanks. However, concrete retaining walls have some obvious defects. On the one hand, the self-weight of concrete retaining walls is relatively large, requiring a high bearing capacity of the foundation. In some areas with poor geological conditions, the construction difficulty is great and the cost is high. On the other hand, the construction period of concrete retaining walls is relatively long, and it needs to go through multiple complex processes such as formwork installation, steel bar binding, concrete pouring and maintenance, which to a certain extent affects the project progress. In addition, once a concrete retaining wall is damaged, the repair difficulty is relatively large and the repair cost is also relatively high.
[0003] With the development of material science and engineering technology, plastic steel sheet piles have gradually come into people's view. However, ordinary plastic steel sheet piles have deficiencies in structural strength, especially in the bending parts, where they are prone to break due to excessive stress, resulting in their inability to effectively meet the requirements of projects such as riverbank reinforcement in practical applications and being difficult to replace concrete retaining walls to play the role of stabilizing riverbanks. Therefore, it is of great practical significance to develop a plastic steel sheet pile with good anti-breaking performance. Content of the Utility Model
[0004] The purpose of the utility model is to provide a plastic steel sheet pile with an anti-breaking structure to solve the problems put forward in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A plastic steel sheet pile with an anti-breaking structure, including a plastic steel sheet pile body. Connecting strips and connecting frames are integrally formed on both sides of the plastic steel sheet pile body respectively. The connecting strips and connecting frames are used to connect adjacent two plastic steel sheet pile bodies. Hoop plates are fixed at both ends of the plastic steel sheet pile body, and a reinforcing angle bar is fixed between the two hoop plates. The reinforcing angle bar is fixed at the bending part of the plastic steel sheet pile body.
[0006] Preferably, the connecting strip is in a "convex" shape strip, and the connecting frame is in a "C" shape strip. When adjacent two plastic steel sheet pile bodies are spliced, the connecting strip on one side of a plastic steel sheet pile body is inserted into the connecting frame on one side of another plastic steel sheet pile body. The heights of the plastic steel sheet pile body, the connecting strip and the connecting frame are equal.
[0007] Preferably, an embedding groove is opened on the surface of the connecting strip. The height of the embedding groove is equal to the height of the connecting strip. A rubber support strip is fixed inside the embedding groove. The width of the rubber support strip is smaller than the width of the embedding groove. A top support strip is fixed on one side of the rubber support strip. When the rubber support strip is in an initial state, the top support strip is pushed out of the embedding groove by the rubber support strip for a certain distance.
[0008] Preferably, the hoop plates are fixed at the internal corners at the ends of the plastic steel sheet pile body. The reinforcing angle bars are in the shape of "L" bars. There are multiple reinforcing angle bars, and the multiple reinforcing angle bars are respectively fixed at multiple bends at the internal corners of the plastic steel sheet pile body.
[0009] Preferably, reinforcing ribs are integrally formed at the external corner bends of the plastic steel sheet pile body.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] The plastic steel sheet pile with an anti-breakage structure proposed by the present utility model; "convex" shaped connecting bars and "C" shaped connecting frames are respectively arranged on both sides of the plastic steel sheet pile body. When adjacent plastic steel sheet piles are spliced, the connecting bars are inserted into the connecting frames. Meanwhile, mounting grooves are formed on the surfaces of the connecting bars, and rubber support bars are fixed in the mounting grooves. A top support bar is fixed on one side of the rubber support bar. When two plastic steel sheet piles are assembled end to end, the top support bar is squeezed into the mounting groove, and the rubber support bar is deformed under pressure and rebounds to push the top support bar against the inner side of the connecting frame, cooperating with the rubber support bar to form a buffer structure between the connecting bar and the connecting frame. This design makes the splicing of the connecting bar and the connecting frame more firm, effectively avoiding the loosening and separation between adjacent plastic steel sheet piles, and improving the stability of the entire plastic steel sheet pile structure.
[0012] Hoop plates are fixed at the internal corners at both ends of the plastic steel sheet pile body, and multiple "L" shaped reinforcing angle bars are respectively fixed at multiple bends at the internal corners of the plastic steel sheet pile body between the two hoop plates. The hoop plates and the reinforcing angle bars form an anti-breakage reinforcement framework. In addition, reinforcing ribs are integrally formed at the external corner bends of the plastic steel sheet pile body. These structural designs respectively play a reinforcing role at the internal and external corners of the plastic steel sheet pile body, can effectively disperse and bear stresses from different directions, avoid the bending phenomenon of the plastic steel sheet pile body when stressed, greatly improve the anti-breakage performance of the plastic steel sheet pile, and extend its service life.

[0020] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0021] Please refer to Figures 1-6 , the present utility model provides a technical solution: a plastic steel sheet pile with an anti-break structure, including a plastic steel sheet pile body 1. Connecting strips 2 and connecting frames 3 are integrally formed on both sides of the plastic steel sheet pile body 1 respectively. The connecting strips 2 and the connecting frames 3 are used to connect adjacent two plastic steel sheet pile bodies 1. The connecting strip 2 is in the shape of a "convex" strip, and the connecting frame 3 is in the shape of a "C" strip. When two adjacent plastic steel sheet pile bodies 1 are spliced, the connecting strip 2 on one side of one plastic steel sheet pile body 1 is inserted into the connecting frame 3 on one side of the other plastic steel sheet pile body 1. The heights of the plastic steel sheet pile body 1, the connecting strip 2 and the connecting frame 3 are equal. An embedding groove 4 is formed on the surface of the connecting strip 2. The height of the embedding groove 4 is equal to the height of the connecting strip 2. A rubber support strip 5 is fixed inside the embedding groove 4. The width of the rubber support strip 5 is smaller than the width of the embedding groove 4. A top support strip 6 is fixed on one side of the rubber support strip 5. When the rubber support strip 5 is in the initial state, the top support strip 6 is pushed out of the embedding groove 4 by the rubber support strip 5 for a certain distance. When the two plastic steel sheet pile bodies 1 are assembled end to end through the connecting strips 2 and the connecting frames 3, the top support strip 6 is squeezed into the embedding groove 4. At this time, the rubber support strip 5 is compressed and deformed, and the rubber support strip 5 rebounds to push the top support strip 6 against the inner side of the connecting frame 3, cooperating with the rubber support strip 5 to form a buffer structure between the connecting strip 2 and the connecting frame 3, so that the connection between the connecting strip 2 and the connecting frame 3 is firm.
[0022] Both ends of the plastic steel sheet pile body 1 are fixed with hoop plates 7, and reinforcing corner strips 8 are fixed between the two hoop plates 7. The reinforcing corner strips 8 are fixed at the bends of the plastic steel sheet pile body 1. The hoop plates 7 are fixed at the inside corners of the ends of the plastic steel sheet pile body 1. The reinforcing corner strips 8 are L-shaped strips, and multiple reinforcing corner strips 8 are provided. Multiple reinforcing corner strips 8 are fixed at multiple bends at the inside corners of the plastic steel sheet pile body 1. The outside corners of the plastic steel sheet pile body 1 are integrally formed with reinforcing ribs 9. The bending-resistant reinforcing skeleton formed by the hoop plates 7 and the reinforcing corner strips 8 plays a reinforcing role at the inside corners of the plastic steel sheet pile body 1, and the reinforcing ribs 9 play a reinforcing role at the outside corners of the plastic steel sheet pile body 1, preventing the plastic steel sheet pile body 1 from bending. Multiple plastic steel sheet pile bodies 1 are arranged and installed along the river channel to replace concrete retaining walls and enhance the stability of the riverbank.
[0023] Method for using PVC sheet piles with anti-breakage structure: Connect two PVC sheet piles end-to-end. Align the "U"-shaped connecting strip 2 on one side of the PVC sheet pile body 1 with the "C"-shaped connecting frame 3 on the other side of the PVC sheet pile body 1. Slowly insert the connecting strip 2 into the connecting frame 3. During insertion, the inner side of the connecting frame 3 will compress the top support strip 6, forcing it into the mounting groove 4. At this time, the rubber support strip 5 deforms under pressure. After the connecting strip 2 is fully inserted into the connecting frame 3, the rubber support strip 5 rebounds and pushes the top support strip 6, causing the top support strip 6 to rest against the inner side of the connecting frame 3. Together with the rubber support strip 5, they form a buffer structure between the connecting strip 2 and the connecting frame 3, ensuring a firm connection. Following this splicing method, connect multiple PVC sheet piles end-to-end to form a single structure. Arrange and install the spliced PVC sheet piles along the river channel to replace concrete retaining walls and enhance riverbank stability. During installation, ensure the plastic steel sheet piles are installed accurately and with the required verticality. Appropriate fixing methods (such as driving them into the ground or connecting them to other supporting structures) can be used to secure the plastic steel sheet piles according to actual project needs. During use, the flexural reinforcement framework formed by the hoop plates 7 and reinforcing corner strips 8 reinforces the internal corners of the plastic steel sheet pile body 1, while the reinforcing ribs 9 reinforce the external corners of the plastic steel sheet pile body 1. This effectively prevents bending of the plastic steel sheet pile body 1, ensuring the stability and reliability of the entire plastic steel sheet pile structure in river applications.
