[0002] A sheet pile refers to a plate-shaped pile driven into a foundation to resist horizontal pressure and water pressure. The sheet pile is mainly used for cofferdams or seepage prevention in water conservancy projects. Common sheet piles are wood sheet piles and steel sheet piles. At present, in river revetment engineering construction, prefabricated concrete sheet piles are a common revetment structure material.
