[0018] A pair of circular columns 2 are connected to the top of the box pile 1. The bottoms of the two circular columns 2 are welded to both sides of the box pile 1 along its length, with their bottoms touching. The tops of the two circular columns 2 slope outwards, forming a Y-shape with the sides of the box pile 1. Support plates 24 are provided on both sides of the box pile 1 along its length, extending along the length of the box pile 1 and connecting the circular columns 2 and the box pile 1. During installation, the circular columns 2 are hoisted to their corresponding positions using a tower crane and then welded to the bottom box column.

[0019] The circular column 2 comprises a first column body 21 at the upper portion and a second column body 22 at the lower portion, the first column body 21 and the second column body 22 are internally provided with a connecting column, the connecting position of the first column body 21 and the second column body 22 is provided with a plurality of connecting plates 23 arranged along the circumferential direction, the connecting plates 23 extend along the axial direction of the circular column 2, and the two ends of the connecting plates 23 are connected to the first column body 21 and the second column body 22 respectively.
