Catwalk arrangement method for suspension bridge with four main cables and different sags
The invention discloses a catwalk arrangement method for a four-main-cable suspension bridge with different sags, and relates to the field of bridge engineering. The catwalk arrangement method comprises the following steps that the center-to-center distance between an inner main cable and an outer main cable on a single side on a transverse bridge is L, and the center-to-center distance is compared with a catwalk cross section design value; when the cross section of the catwalk is smaller than the design value of the cross section of the catwalk, a catwalk with the design value of the cross section of the catwalk is erected for each main cable, the part, located between the centers of the inner main cable and the outer main cable in the transverse bridge direction, of the catwalk is defined as a first catwalk, the remaining part is defined as a second catwalk, and the sum of the widths of the two first catwalks in the transverse bridge direction is smaller than L; main cable erecting devices are arranged on the second catwalk, and the main cable erecting devices of the inner main cable and the outer main cable on the single side form a traction system. The catwalk provided by the invention can meet the construction scenes with different distances between the inner main cable and the outer main cable, and can be used for constructing catwalks of four-main-cable suspension bridges with different sags.
本发明公开了一种不同垂度四主缆悬索桥的猫道布置方法，涉及桥梁工程领域。本发明的猫道布置方法包括以下步骤：单侧内外两根主缆在横桥上的中心间距为L，并与猫道横断面设计值对比；当小于猫道横断面设计值时，给每条主缆架设一条具有猫道横断面设计值的猫道，并将该猫道位于内外两根主缆在横桥向上的中心之间的部分定义为第一猫道，余下部分定义为第二猫道，其中，两个第一猫道在横桥向上的宽度和小于L；在第二猫道设置主缆架设装置，单侧内外两根主缆的主缆架设装置构成牵引系统。本发明的猫道可满足不同内外主缆间距的施工场景，并且可对于不同垂度四主缆悬索桥的猫道进行搭建。
