Steel sheet pile is widely used in civil engineering. Steel sheet pile has high strength and can withstand large lateral earth pressure and water pressure, which is suitable for deep foundation pit and river bank protection. Secondly, the construction efficiency is high, the installation speed is fast, which can shorten the construction period and reduce the cost. In addition, the steel sheet pile has excellent waterproof performance, which can effectively prevent water penetration and protect the surrounding environment. Finally, the steel sheet pile can be reused, strong adaptability, good corrosion resistance, suitable for use in harsh environments.
