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.

The construction of steel sheet piles reduces the amount of soil excavation and the use of cement concrete, effectively protecting land resources and reducing environmental damage. At the same time, the recycling and utilization of steel sheet piles also conforms to the concept of green environmental protection. In flood control and disaster relief, steel sheet piles can be used for tasks such as flood control, collapse prevention, and quicksand prevention. Their timeliness and effectiveness provide strong support for disaster relief work.
