Space cable special-shaped steel tower self-anchored suspension bridge and construction method thereof
The invention relates to a space cable special-shaped steel tower self-anchored suspension bridge and a construction method thereof, and belongs to the technical field of bridge construction. Comprising the following steps: S1, dividing a construction area; s2, bridge construction; s3, tower column construction; s4, closure is conducted; s5, catwalk and main cable erection; s6, converting a main cable system; s7, the main cable is fixed, a cable clamp and a permanent suspender are installed on the main cable after the step S6 is completed, and system conversion is completed; the transverse top support comprises two top rods and a supporting rod, the supporting rod is a hollow shaft body, stepped holes are formed in the two ends of the supporting rod, stepped shafts are arranged at one ends of the top rods, threads are arranged on the stepped shafts, the intervals of the threads are sequentially reduced along steps, threads matched with the stepped shafts are arranged on the stepped holes, and the two top rods are in threaded connection with the stepped holes through the stepped shafts respectively. The space self-anchored suspension bridge solves the problem that an existing space self-anchored suspension bridge is large in construction difficulty due to the influence of large system transformation deformation.
本发明涉及一种空间缆异型钢塔自锚式悬索桥及其施工方法，属于桥梁施工技术领域。包括以下步骤：S1：划分施工区；S2：桥梁施工；S3：塔柱施工；S4：合龙；S5：猫道和主缆架设；S6：主缆体系转换；S7：固定主缆，在步骤S6完成后在主缆上安装索夹和永久吊杆，完成体系转换；横向顶撑包括两顶杆和支撑杆，支撑杆为中空轴体且两端均开设有阶梯孔，顶杆的一端开设有阶梯轴，阶梯轴上设有螺纹且螺纹间距沿着阶梯依次减少，阶梯孔上设有与阶梯轴相匹配的螺纹，两顶杆分别通过阶梯轴与阶梯孔螺纹连接，本发明解决了现有的空间自锚式悬索桥在体系转换变形大的影响导致施工难度大的问题。
