Construction method for lower tower column of large-dip-angle variable-cross-section ultrahigh cable bent tower
The invention provides a construction method for a lower tower column of a large-dip-angle variable-cross-section ultrahigh cable bent tower. The construction method comprises the steps that S1, a transition section and a vertical section of the lower tower column of the cable bent tower are constructed through a creeping formwork process; the cable bent tower comprises a lower tower column, and the lower tower column comprises a transition section, a vertical section, a small-dip-angle section and a large-dip-angle section from bottom to top; s2, a small-dip-angle section of the lower tower column is constructed by adopting a steel rollover formwork and creeping formwork combined process; and S3, the large-dip-angle section of the lower tower column is constructed through the combined technology of a steel rollover formwork, a hanging frame and a creeping formwork. Different construction technologies are adopted for different positions of the lower tower column, the line type of the tower column is guaranteed, meanwhile, turnover use of formworks can be increased as much as possible, the construction cost is reduced, and the construction efficiency is improved.
本发明提供一种大倾角变截面超高索塔下塔柱的施工方法，包括：S1、采用爬模工艺施工索塔的下塔柱的过渡段和竖直段；其中，索塔包括下塔柱，下塔柱自下而上包括过渡段、竖直段、小倾角段以及大倾角段；S2、采用钢翻模+爬模的组合工艺施工下塔柱的小倾角段；S3、采用钢翻模+挂架+爬模的组合工艺施工下塔柱的大倾角段。本发明对下塔柱不同位置采用不同的施工工艺，在保证塔柱线型的同时，能够尽可能增加模板的周转使用，减少施工成本，提高施工效率。
