U-shaped steel sheet pile, also known as Larsen steel sheet pile, is a widely used type of steel sheet pile. The shape of U-shaped steel sheet pile presents a "U" shape, consisting of a longitudinal thin plate and two parallel edge plates. This design gives U-shaped steel sheet piles high strength and stability.

Steel sheet pile construction is simple, with a short construction period, and can quickly complete engineering tasks such as foundation pit support and cofferdam. During the construction process, steel sheet piles can be reused, improving material utilization and reducing engineering costs. On temporary structures, steel sheet piles can be used for retaining soil, water, and sand in projects such as mountain sealing, temporary bank expansion, flow interruption, bridge and cofferdam construction, and temporary trench excavation for large pipeline laying.
