Variable-width tower-penetrating four-amplitude catwalk structure of high-low four-main-cable suspension bridge and construction method of variable-width tower-penetrating four-amplitude catwalk structure
The invention provides a widening tower-penetrating four-amplitude catwalk structure of a high-low four-main-cable suspension bridge and a construction method. The widening tower-penetrating four-amplitude catwalk structure comprises a high-low four-amplitude catwalk structure, a catwalk widening structure, a catwalk tower-penetrating structure and a wind-resistant and impact-resistant system. The line shape of the four-amplitude catwalk structure is completely matched with the line shape of four high-low main cables, the inner catwalk and the outer catwalk are independently arranged to form a plurality of working faces, and the four-amplitude catwalk structure can well adapt to the line shape change of the main cables during construction of the upper structure of the suspension bridge with the four high-low main cables; a variable cross-section catwalk structure is adopted, the cross section of a near-tower-area catwalk is converted into a narrow catwalk cross section, and the problems that the transverse distance between inner and outer catwalks is small, and space interference is caused are solved. The catwalk section is integrally symmetrical, and the overall safety is high; a catwalk tower penetrating structure is adopted, the tower top operation space is not occupied, and the problem that the tower top operation space of a high-low four-main-cable suspension bridge is insufficient is solved; a wind-resistant and impact-resistant system with a vibration control cable and an anti-collision device is adopted, the wind-resistant and impact-resistant performance of the high-low four-amplitude catwalk structure is integrally improved, and the problem of collision caused by wind is solved.
本发明提供了高低四主缆悬索桥的变宽穿塔四幅式猫道结构及施工方法，包括高低四幅式猫道结构、猫道变宽结构、猫道穿塔结构和抗风防冲击系统；四幅式猫道结构的线形完全匹配高低四主缆线形，内外侧猫道独立设置，形成多个作业面，可以很好地适应高低四主缆悬索桥上部结构施工时主缆线形变化；采用了变截面猫道结构，近塔区猫道截面转化为窄猫道截面，解决了内外侧猫道横向间距小、空间干涉问题。猫道截面整体对称，总体安全性高；采用了猫道穿塔结构，不占用塔顶作业空间，解决了高低四主缆悬索桥塔顶作业空间不足的难题；采用了制振索+防撞装置的抗风防冲击系统，整体提高了高低四幅猫道结构的抗风抗冲击性能，解决了风致碰撞问题。
