AI Technical Summary
Technical Problem
Traditional formwork technology is inefficient and poses high safety risks in the construction of hollow piers, and ordinary climbing formwork technology cannot solve the problem of diameter variation in hollow pier structures.
Method used
By adopting a variable diameter climbing formwork system and a circular arc template, the curvature of the plates can be adjusted to adapt to any variable diameter position of the hollow pier. Combined with the design of the steel profiles and adjusting screws, the hollow pier can be cast in place.
Benefits of technology
It improves the safety and efficiency of hollow pier construction, can adapt to any diameter change position of hollow pier, and achieves efficient mold-forming and casting.

Abstract
The utility model discloses a variable-diameter creeping formwork system of an ultrahigh aqueduct hollow pier, an arc formwork and an adjusting plate of the arc formwork, and relates to the technical field of building construction. At least one base is transversely arranged on the outer side face of the adjusting plate; adjusting lead screws are hinged to the two side edges of the adjusting plate. When one base is arranged, the two adjusting lead screws are located on the two sides of the base respectively and hinged to the base. When the number of the bases is multiple, the two adjusting lead screws are hinged to the bases close to the outermost sides of the adjusting lead screws correspondingly; the length of the adjusting screw rod is variable; and the length of the adjusting screw rod is changed so as to change the radian of the adjusting plate. By the adoption of the scheme, the adjusting plates with the corresponding size and number can be selected, the radian can be changed, the adjusting device can be matched with any reducing position of the hollow pier, and die assembly pouring of the hollow pier is achieved.
