Damping stay cable construction method of double-tower double-cable-plane steel-concrete composite beam cable-stayed bridge
The invention relates to a damping stay cable construction method of a double-tower double-cable-plane steel-concrete composite beam cable-stayed bridge, and belongs to the technical field of stay cable construction. S1, stay cable prefabrication; s2, determining the position of a cable hole; s3, mounting a cable guide pipe; s4, cable releasing construction is conducted; s5, hanging cable construction at the beam end and the tower end; s6, tensioning construction of the stay cable is conducted; the cable guide pipe comprises a guide pipe, a fixed pipe, an electromagnet, a connecting ring and an extrusion ring, the connecting ring is made of a flexible material, the connecting ring is a hollow circular ring and is filled with an expansion plastic anchoring agent, an outer ring of the connecting ring is connected with the inner side wall of the fixed pipe, and an inner ring of the connecting ring is connected with the outer side wall of the guide pipe; the electromagnet is mounted on the inner side wall of the connecting ring and close to one side of the fixed pipe; the extrusion ring slides in the connecting ring and is electromagnetically connected with the electromagnet; the problem that in the construction process of the stay cable, the mounting position of the cable guide pipe is prone to positioning deviation, and consequently the stay cable is abraded in the tensioning process is solved.
本发明涉及一种双塔双索面钢混组合梁斜拉桥的减震斜拉索施工方法，属于斜拉索施工技术领域。S1：斜拉索预制；S2：索孔位置确定；S3：索导管安装；S4：放索施工；S5：梁端和塔端挂索施工；S6：斜拉索的张拉施工；索导管包括导向管、固定管、电磁铁、连接环和挤压环，连接环由柔性材料构成，连接环为空心圆环且连接环内填充有膨胀塑料锚固剂，连接环的外环与固定管内侧壁连接，内环与导向管的外侧壁连接，电磁铁安装于连接环内侧壁并靠近于固定管的一侧，挤压环滑动连接环内并与电磁铁电磁连接；本发明解决了斜拉索在施工过程中索导管的安装位置极易出现定位偏差而导致斜拉索在进行张拉过程中出现磨损的问题。
