| description | The invention relates to a processing method of a hyperboloid template of a variable cross-section cylindrical pier, which comprises the following steps of: bending a plurality of strip-shaped steel plates into semicircles along the longitudinal direction, sequentially welding a plurality of semicircular steel plate strips into a whole along the transverse direction according to the height of a pouring section of a pier column, and assembling the plurality of steel plates according to the longitudinal curvature of the section of the pier column by adopting a straight method instead of a curved method, forming a hyperboloid template; a weld joint on the inner wall of the double-curved-surface template is ground and flattened; a layer of putty is brushed along the weld joint of the inner wall of the formwork, the pits are densely filled with the putty, and after the putty is hard dry, the putty is polished to be flat; and then the inner wall of each template is coated with template paint, and the template can b |
