This material has the advantages of high strength, good durability, corrosion resistance, etc., so it has broad application potential in engineering construction. In particular, in water conservancy projects, high-strength plastic steel sheet piles are mostly used for cofferdams or seepage prevention, and can also be used as permanent earth-retaining structures. In waterway engineering, the application research of high-strength plastic steel sheet piles shows that its high strength, good durability, corrosion resistance, etc. make it an optimal material for waterway engineering construction. In addition, in the field of ecological revetment, high-strength plastic steel sheet piles are widely used in the construction of ecological revetment due to their environmental protection, economic efficiency, etc., while supporting plant growth and fish habitat, promoting the maintenance of ecological balance.

[0003] Although high-strength plastic steel sheet piles have the advantages of light weight, high strength, corrosion resistance, and strong weather resistance, they still have a gap in hardness compared to manganese steel. This means that plastic steel sheet piles may not be as effective as manganese steel in resisting damage when faced with high-strength impacts.

[0004] When high-strength plastic steel sheet piles are installed, they are sent into the ground through a guide clamp. However, when encountering complex underground geology, such as stones, underground cement mixing piles, etc., the plastic steel sheet piles are prone to bending, resulting in breakage.

[0005] As disclosed in patent CN112482412A, a high-strength plastic steel sheet pile and its construction method are provided. The high-strength plastic steel sheet pile body is integrally formed, and C-shaped and T-shaped locks are arranged on both sides of the body. Adjacent high-strength plastic steel sheet pile bodies are connected through the C-shaped and T-shaped locks. The construction method includes the following steps: S1, guide groove installation; S2, clamping and sending pile plate; S3, fixing plastic steel sheet pile; S4, C, T-shaped lock connection; S5, pile sending and calibration; S6, removing the pile plate; S7, head compression; S8, dredging and filling; S8, hydrophilic platform pouring. However, when encountering hard objects such as stones and underground cement mixing piles during construction, the plastic steel sheet piles are prone to bending. UTILITY MODEL CONTENTS
