[0003] In the single-pile manufacturing process, due to its huge size, it often needs to be manufactured in sections, and then welded for closing-up butt joint at the construction site or wharf. The geometric precision (mainly including circumference, diameter, roundness, ovality and end face flatness) of the closing-up opening is one of the most critical factors for determining the closing-up welding quality, structural integrity and service safety.

[0004] The existing measurement method is generally that an operator uses a long steel tape to manually measure the circumference along the end inner wall or outer wall of the closing-up opening, which is extremely low in efficiency and difficult to guarantee precision. SUMMARY
