Construction method for overall erection of catwalk bearing cable of suspension bridge
The invention relates to a construction method for integrally erecting catwalk bearing cables of a suspension bridge, which comprises the following steps of: S1, placing a plurality of first catwalk bearing cable trays in front of a north anchorage, drawing out first catwalk bearing cables on the first catwalk bearing cable trays, anchoring the first catwalk bearing cables on first anchor beams in sequence, arranging a first winch at the bottom of a north cable tower, and arranging a second winch at the bottom of the north cable tower; the first anchor beam is dragged to the bottom of the north cable tower through a first winch; and S2, a plurality of second catwalk bearing cable trays are placed in front of a south side anchorage, second catwalk bearing cables on the second catwalk bearing cable trays are pulled out and are sequentially anchored to a second anchor beam, a second winch is arranged at the bottom of a south side cable tower, and a second winch is used for pulling the second anchor beam to the bottom of the south side cable tower. A reciprocating traction system does not need to be arranged, the catwalk bearing cable erecting speed is high, the construction efficiency is high, and the construction period can be remarkably shortened.
本发明是一种悬索桥猫道承重索整体架设的施工方法，包括以下步骤：S1、将若干第一猫道承重索索盘安放在北侧锚碇前，抽出第一猫道承重索索盘上的第一猫道承重索，按顺序依次锚固于第一锚梁上，在北侧索塔底设置第一卷扬机，用第一卷杨机牵引第一锚梁至北侧索塔底；S2、将若干第二猫道承重索索盘安放在南侧锚碇前，抽出第二猫道承重索索盘上的第二猫道承重索，按顺序依次锚固于第二锚梁上，在南侧索塔底设置第二卷扬机，用第二卷杨机牵引第二锚梁至南侧索塔底。本发明无需布设往复牵引系统，猫道承重索架设速度快，施工效率高，可显著减少工期。
