[0002] Currently, steel pipe piles are widely used in bridges and temporary building structures, including but not limited to key structures such as steel trestle bridges over water, bridge cap beams, and cast-in-place scaffolding. The primary load-bearing deformation of steel pipe pile foundations is compressive buckling, and the performance evaluation indicators are critical load and local stress. Therefore, the deviation of the butt joint axis, the included angle, and the mechanical properties of the circumferential weld of the steel pipe piles are very important.

The device is used for steel pipe piles that are horizontally and rotatably mounted on a roller frame. It includes a support beam that horizontally passes through the steel pipe pile, with supports fixed to the ground at both ends. A traveling trolley that moves along the axial direction of the steel pipe pile is mounted on the support beam. A positioning element that can swing along the axial direction of the steel pipe pile is installed on the traveling trolley. The positioning element extends towards the inner wall of the steel pipe pile, and its end has a roller that rotatably abuts against the inner wall of the steel pipe pile.
