Hot-rolled steel sheet piles mainly have three shapes: U-shaped steel sheet piles, Z-shaped steel sheet piles and linear steel sheet piles, as shown in Figure 1. Among them, Z-shaped steel sheet piles and linear steel sheet piles are relatively complicated in production, processing and installation. The price is 1/3 higher than that of U-shaped steel sheet piles.

Steel sheet pile construction adopts vibration pile sinking construction, erecting single-layer double-sided guide frames, and screen-type driving method to drive steel sheet piles.
