Construction method for hollow lower tower column with embedded steel ring of cable bent tower
The invention relates to a construction method for a hollow lower tower column with an embedded steel ring of a cable bent tower. The construction method comprises the following steps: constructing a pile foundation and a bearing platform; construction of concrete vibration and strike-off moving hanging brackets is poured in a segmented mode; constructing a first section of a lower tower column of the cable bent tower; constructing a second section of the lower tower column of the cable bent tower; constructing a third section of the lower tower column of the cable bent tower; and constructing the fourth section of the lower tower column of the cable bent tower. The construction method has the beneficial effects that the formwork adopts the segmental steel formwork, the lower tower column steel formwork is designed to be of a truss structure, one section of formwork is installed as an upper layer tower column construction platform after steel bar binding construction is completed, the construction platform does not need to be independently built, and the construction efficiency is effectively improved; an embedded steel ring annular pull connection stabilizing system, an anti-deformation inner support and an embedded steel ring bag water filling ballasting system are combined, and it is effectively ensured that an embedded steel ring does not float upwards when concrete is poured; the lower tower column is poured in sections, and poured concrete is vibrated and stricken in sections, so that smooth construction of the hollow lower tower column with the embedded steel ring in the cable bent tower is effectively guaranteed.
本发明涉及一种索塔内嵌钢圈镂空下塔柱的施工方法，包括步骤：桩基与承台施工；分节浇筑混凝土振捣与刮平移动吊架施工；索塔下塔柱第一节段施工；索塔下塔柱第二节段施工；索塔下塔柱第三节段施工；索塔下塔柱第四节段施工。本发明的有益效果是：模板采用分节段钢模，下塔柱钢模设计为桁架结构，钢筋绑扎每施工完一段安装一节模板作为上层塔柱施工平台，无需单独搭建施工平台，有效提高了施工效率；联合采用内嵌钢圈环向拉接稳固体系+防变形内支撑、内嵌钢圈囊袋灌水压重体系，有效确保了在浇筑混凝土时内嵌钢圈不上浮；下塔柱分节浇筑、浇筑混凝土分节振捣与刮平有效保证了索塔内嵌钢圈镂空下塔柱的顺利施工。
