1. The pile length is easy to adjust. The length of steel sheet piles can be lengthened or cut as needed.
2. Connector connection is very simple. It can be welded by electric welding, which is simple to operate, high in strength and safe to use.
3. The amount of abandoned soil is small and has little impact on adjacent buildings (structures). Due to the opening at the lower end of the pile, soil will be squeezed into the pile tube when the pile is driven. Compared with actual piles, the amount of soil squeezed is greatly reduced, causing little disturbance to the surrounding foundation, avoiding soil uplift, and greatly reducing the effects of vertical displacement and horizontal displacement of the pile top.
