Currently, most bridges across rivers, seas and lakes are built with steel trestles as construction and transportation channels. However, the design length of trestles' steel pipe piles is generally long, some exceeding 50 meters. The existing construction method usually directly welds steel pipes in the front field, but this method has a slow construction speed and delays the construction time in the front field. Therefore, processing steel pipes in the back field and then transporting them to the front field for direct connection can improve construction efficiency, but if the steel pipe piles processed in the back field are transported to the front field for construction, it is a major technical problem in trestles construction. Summary of the invention

[0003] In order to solve the above problems, the purpose of the utility model is to provide a steel pipe pile that can be transported with a length of more than 50 meters, which is convenient for workers to transport the steel pipe piles processed in the back field to the front field for direct insertion. A single steel pipe pile can save at least 5 hours of welding time for steel pipe piles in the front field, greatly improving the construction speed of the front field, saving construction period, and the manufacturing process is simple and convenient, and the manufacturing cost is low.
