Construction method of asymmetric cantilever beam of cable-stayed bridge
The invention relates to a construction method of an asymmetric cantilever beam of a cable-stayed bridge. The construction method comprises the following steps: constructing a mid-span 0 # block and a side-span 0 # block on a tower column; a middle-span 1 # block and a side-span 1 # block are respectively mounted on a bracket based on the tower column; a bridge deck crane is installed on the mid-span 1 # block, and a guy cable hanging basket is installed on the side-span 1 # block; the mid-span is assembled through the deck crane till the mid-span is folded, and balance weight is achieved through the balance weight type tension-compression auxiliary piers on the side span sides; and the side spans are spliced through the guyed hanging baskets till the side spans are folded, and balance weight is achieved through the unbalanced weight modules on the middle span side. After the 1 # block of the side span and the middle span is installed, a guy cable hanging basket is installed on the side span side, and a bridge deck crane is installed on the middle span side, so that all the sections of the side span main beam and the middle span main beam can be constructed at the same time, stay cables can be installed at the same time, and it is guaranteed that the stresses of the stay cables on the corresponding sections are the same; therefore, the stability and linetype of the bridge during and after the construction process of the cable-stayed bridge are ensured.
本发明涉及一种斜拉桥不对称悬臂梁的施工方法，包括以下步骤：在塔柱上施工中跨0#块和边跨0#块；基于塔柱的托架分别安装中跨1#块和边跨1#块；在所述中跨1#块上安装桥面吊机，在所述边跨1#块上安装牵索挂篮；利用所述桥面吊机拼装中跨直至中跨合拢，利用边跨侧的配重式拉压辅助墩实现平衡配重；利用所述牵索挂篮拼装边跨直至边跨合拢，利用中跨侧的不平衡配重模块实现平衡配重。在边跨和中跨的1#块安装完成之后，则在边跨侧安装牵索挂篮，中跨侧安装桥面吊机，进而使得边跨主梁和中跨主梁每一节块都能够同时施工且斜拉索也能同时安装，保证了相对应节块上斜拉索的应力相同，以保证斜拉桥施工过程中和之后桥梁的稳定性和线型。
