Description

Technical Field

[0001] This utility model relates to a combined hollow plastic steel sheet pile, which is mainly used in water conservancy construction, municipal engineering, and port construction, such as coastline protection, land reclamation, pond cofferdams, offshore wind power foundation pits, roadbed protection, building foundation pits, soft soil, and scenarios requiring acid and salt resistance. Depending on the waterproofing requirements of the application scenario, plastic steel sheet piles with or without sealing strips can be selected. Background Technology

[0002] Existing plastic steel sheet piles are mostly single-piece structures, which are easy to bend, have low strength, and are shallow in the ground. When using them, multiple plastic steel sheet piles need to be connected and installed together. Moreover, the connectors and the main body of the sheet pile are mostly integrated structures, which makes the entire plastic steel sheet pile large in size and inconvenient to transport. Utility Model Content

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: This combined hollow plastic steel sheet pile includes a sheet pile body and independent connecting parts. Adjacent sheet pile bodies are connected by independent connecting parts. Its structural features are: the sheet pile body and the independent connecting parts are separate structures; the sheet pile body is integral and hollow; a first connecting ear and a second connecting ear are respectively provided on both sides of the sheet pile body; the first connecting ear and the second connecting ear in adjacent sheet pile bodies are connected by independent connecting parts. This design offers low maintenance costs, convenient replacement of independent connecting parts, and allows for the extension of the distance between two sheet pile bodies without changing the sheet pile body itself, resulting in more flexible combinations.

[0005] Furthermore, the independent connector is provided with a third connecting ear and a fourth connecting ear on both sides, the first connecting ear is connected to the fourth connecting ear, and the second connecting ear is connected to the third connecting ear.

[0006] Furthermore, the sheet pile body is provided with reinforcing ribs.
