Lower tower column tension-compression structure for cable bent tower and method thereof
The invention discloses a lower tower column tension-compression structure for a cable bent tower and a method thereof. A driving pull rod and a supporting rod are arranged at the position of a lowertower column of the cable bent tower which is prone to deformation. When the lower tower column of the cable bent tower is constructed; the bottom of the lower tower column of the cable bent tower ismounted on the top surface of a bearing platform; the slope of the outer side surface of the lower tower column of the cable bent tower is 1/4.356; an auxiliary pull rod is arranged at the position, away from the top face of the bearing platform by 9 m, in a tower column of the cable bent tower, the auxiliary pull rod is composed of phi s15.2 mm high-strength low-relaxation steel strands, and allthe phi s15.2 mm high-strength low-relaxation steel strands are wrapped by a steel pipe. In combination with the method, the defects that in the prior art, the strength of a support for construction of the lower cross beam of the cable bent tower and the convenience of construction are insufficient, no treatment measure exists for the position, prone to deformation, of the lower tower column of the cable bent tower, and the deformation resistance of the lower tower column is poor are effectively overcome.
一种用于索塔的下塔柱拉压结构及其方法，包括在容易出现变形的索塔的下塔柱的位置设置有主动拉杆和撑杆。所述索塔的下塔柱施工时，所述索塔的下塔柱的底部安装在承台的顶面，所述索塔的下塔柱的外侧面的斜率为1/4.356，所述索塔的塔柱内距承台顶面距离为9m的位置上设置有副拉杆，所述副拉杆为采用Фs15.2mm高强低松弛钢绞线组成的拉杆，所有的Фs15.2mm高强低松弛钢绞线由一钢管外包。结合其方法有效避免了现有技术中针对索塔的下横梁施工用的支架的强度和针对施工的便利性很不足、对索塔的下塔柱容易出现变形的地方没有任何处理措施使得其抗变形能力不佳的缺陷。
