Generally refers to the tip of the prestressed pipe pile. It is used for the foundation construction of the prestressed concrete pipe pile and the front end of the pipe pile. It is installed on the pipe pile to guide and block the pipe pile when the pipe pile sinks.
Generally, in the construction of prefabricated piles, the pile tip is welded at the pile head and the pile body is brought into the soil to avoid the pile head damage and pile body tilt (verticality control), and the pile body can enter the bearing layer well.
The form of pile tip changed and derived different shapes and specifications with different geology and use methods.
