1. high quality (high strength, light weight, good water insulation); 2. simple construction, shortened construction period; 3. good durability, life expectancy of 20-50 years; 4. inexpensive construction cost; 5. good interchangeability, can be reused 3-5 times; 6. construction of significant environmental protection, a large amount of reduction in the amount of soil extraction and concrete use, and effective protection of land resources 7. disaster relief and emergency relief, such as flood control, collapse, quicksand. The construction has significant environmental protection effect, which reduces the amount of soil extraction and the use of concrete, and protects the land resources effectively; 7. The timeliness of disaster relief and rescue is strong, such as flood control, landslide, subsidence, quicksand.

Steel sheet pile driving method is generally categorized into individual driving method, double-walled purlin insertion method and segmental re-driving method. The steel sheet pile driving method is suitable for steel sheet pile support construction with pile length less than 10m and low engineering requirements.
