Method for installing cable hoisting system of large-span deck type concrete-filled steel tube arch bridge
The invention discloses an installation method for a cable hoisting system of a large-span deck type concrete-filled steel tube arch bridge, which comprises the following steps of: S1, cable tower installation: determining a connection mode of a cable tower frame, assembling the cable tower into a whole from the ground, hoisting and installing the whole on a pier top, dividing a cable tower body into a left part and a right part, and respectively arranging the left part and the right part on a left cover beam and a right cover beam; s2, temporary traction installation: determining a pilot cable river-crossing method, and carrying out temporary traction installation; one end of the ventilation cable is fixed to the right bank, and the other end of the ventilation cable is movably connected with a left bank pulley block; s4, mounting a bearing cable: pulling one end of the bearing cable into the winch from the right bank, and mounting the other end on a left bank pulley block; and S5, permanent traction cable installation: the ends of the permanent traction cable form circulating connection at the ends of the left bank and the right bank. The method can meet the topographic conditions of in-situ platform erection of large-span overwater bridges, canyons and other bridges, breaks through the limitation of the topography and the like, saves the construction period, reduces the cost, and guarantees the construction safety.
本发明公开了一种大跨径上承式钢管混凝土拱桥缆索吊装系统安装方法，包括以下步骤：S1缆塔安装：确定缆塔塔架的连接方式，将缆塔由地面组拼成整件，整体起吊安装于墩顶，缆塔塔身分左右两幅，分别布置于左右两幅盖梁上；S2临时牵引安装：确定先导索过江方法，进行临时牵引安装；S3通风缆安装：所述通风缆一端固定于右岸，另一端与左岸滑轮组活动连接；S4承重索安装：承重索一端从右岸拉入卷扬机，另一端安装于左岸滑轮组上；S5永久牵引索安装：永久牵引索端在左岸和右岸的端头形成循环连接。本发明能够满足大跨径水上、峡谷等桥梁在原位搭设平台的地形条件，突破地形地势等限制，节约工期，降低成本，保障施工安全。
