Hydraulic creeping formwork construction method for tower column of arched single-tower cable-stayed bridge
The invention provides a hydraulic creeping formwork construction method for a tower column of a circular-arch-shaped single-tower cable-stayed bridge. The hydraulic creeping formwork construction method comprises the following steps that S1, foundation segments are divided; s2, the nth foundation section is poured; s3, the (n + 1) th basic section is poured; s4, demolding the (n + 1) th basic section, driving the climbing operation platform to climb to the (n + 1) th basic section by using power of the hydraulic system, and then driving the template to approach the tower column; s5, the (n + 2) th foundation section is poured; repeatedly demolding and lifting the climbing operation platform on the (n + 2) th foundation section, and sequentially completing the pouring of the (n + 2 + m) th foundation section; wherein the formwork is kept to be gradually inclined along with the change of the inclination rate of the tower column, and the climbing operation platform is kept to be in a horizontal state all the time. The technical problems that in the prior art, the inclination degree of a formwork system cannot be accurately controlled, and changes of the axis and the section of a tower column of a formwork cannot be adapted are solved.
本发明提供了一种圆拱形独塔斜拉桥塔柱液压爬模施工方法，包括以下步骤：S1、划分基础节段；S2、浇筑第n节基础节段；S3、浇筑第n+1节基础节段；S4、第n+1节基础节段脱模，利用液压系统的动力驱动爬升操作平台爬升至第n+1节基础节段上，再驱动模板靠近塔柱；S5、浇筑第n+2节基础节段；在第n+2节基础节段上重复脱模和提升爬升操作平台，依次完成对第n+2+m节基础节段的浇筑；其中，保持模板随塔柱的倾斜率变化而逐渐倾斜，并保持爬升操作平台一直处于水平状态。本发明解决了现有技术中存在的无法精确控制模板系统的倾斜度，无法适应模板的塔柱轴线及截面的变化的技术问题。
