Description

Technical Field

[0001] This utility model relates to the field of pipe pile structure technology, specifically a corrosion-resistant concrete pipe pile structure. Background Technology

[0002] Concrete pipe piles are structural elements commonly used in pile foundation engineering. They are cylindrical structures made of prestressed concrete. Concrete pipe piles are typically prestressed by prestressed steel bars or tendons inserted at the top to enhance the pile's load-bearing capacity and resistance to deformation.

[0003] During installation, pipe piles are erected and moved to the installation area using lifting equipment. The pipe piles are then aligned with the mounting base and supported. Welding equipment is then used to weld the pipe piles to the mounting base. After welding, the pipe piles are removed from the lifting equipment. Although this method is safe and reliable, it takes a long time to use the lifting equipment. When multiple pipe piles need to be installed, it will delay the installation time of other pipe piles. Therefore, a corrosion-resistant concrete pipe pile structure is proposed. Utility Model Content
