Cable-stayed bridge cable tower construction method
The invention belongs to the technical field of cable-stayed bridge cable tower construction, and relates to a cable-stayed bridge cable tower construction method. Positioning the stiff skeleton: processing the stiff skeleton to a set size on a processing site, then positioning on site, and putting the bottom surface of the stiff skeleton in place according to the axis of the existing concrete surface; controlling the top surface: hanging a plumb bob on the axis of the top surface of the stiff skeleton, adjusting the inclination of the plumb bob to coincide with the projection of the axis of the top surface of the stiff skeleton of the constructed section, roughly fixing the stiff skeleton, then erecting an instrument on control points on both banks of a river bank, measuring coordinates of longitudinal and transverse axis points of the stiff skeleton by using a coordinate method, and comparing the coordinates with a set value; the stiff skeleton is adjusted according to the difference value, the longitudinal axis and the transverse axis of the stiff skeleton are measured, and the stiff skeleton is reinforced after positioning of the stiff skeleton is completed. According to the cable-stayed bridge cable tower construction method, the steps are simple, cable-stayed bridge cable tower construction can be conveniently and rapidly completed, errors are reduced, the cable-stayed bridge cable tower operation precision is improved, and the overall construction quality of a cable-stayed bridge is guaranteed.
本发明属于斜拉桥索塔施工技术领域的斜拉桥索塔施工方法。劲性骨架定位：在加工场地将劲性骨架加工到设定尺寸，然后现场定位，劲性骨架底面根据已有混凝土面的轴线就位；顶面的控制是在劲性骨架顶面轴线悬挂垂球，通过调整垂球倾斜度与已施工完毕节段劲性骨架顶面轴线的投影重合，粗略固定劲性骨架，然后架仪器于河堤两岸的控制点，用坐标法测定劲性骨架的纵横轴线点坐标，并与设定值进行比较，根据差值对劲性骨架进行调整，并测设出劲性骨架的纵横向轴线，劲性骨架定位完成后再对劲性骨架进行加固。本发明所述的斜拉桥索塔施工方法，步骤简单，能够方便快捷完成斜拉桥索塔施工，降低误差，提高斜拉桥索塔作业精度，保障斜拉桥整体施工质量。
