AI Technical Summary
Traditional concrete pipe piles are not crack resistance and toughness when they withstand tensile, shear or impact loads, which can easily cause structural damage and failure; the connections of existing steel fiber concrete pipe piles are prone to shake and have low structural strength.
A steel fiber concrete pipe pile was designed, which used fastening rings and fastening bolts to enhance the connection stability, and a composite layer structure was set on the pipe pile, including the outer layer, the steel fiber reinforced layer, the concrete base layer and the inner layer. The steel fibers were evenly distributed to improve crack resistance and toughness.
By enhancing connection stability and improving structural strength, the connecting parts of the pipe piles are not easily loosened or broken when they bear external loads, which improves the reliability and safety of the overall structure; the composite layer structure disperses the stress more evenly, improving the load-bearing capacity and durability.
