Construction method of steel-concrete composite beam of basket arch bridge
The invention discloses a construction method for a steel-concrete composite beam of a basket arch bridge, which belongs to the technical field of arch bridge construction and comprises the following steps: firstly, assembling steel beam sections on site, and during placement, the length direction of the steel beam sections is along the longitudinal direction of the bridge; transporting the steel beam sections from the site to a bridge by adopting a single cable crane; the steel beam sections are lowered to a transport ship through a basket arch midspan side gap, the transport ship turns around to the position where the steel beams are to be erected, and the installation direction of the steel beam sections is adjusted; then, two cable cranes are adopted to be connected with the two lifting points on the steel beam section correspondingly, and double-crane lifting installation is conducted after the installation angle is adjusted; construction of the steel beam sections is completed, and installation of the bridge deck is completed through a crane. According to the construction method, the steel beam sections are transported into the bridge from the site through the single cable crane, a transport ship does not need to transport water from the land, and therefore the problem that when water transport cannot be conducted on a steel beam machining field of the small-span basket arch bridge, steel beam hoisting is difficult is solved.
本发明公开了一种提篮拱桥钢混组合梁施工方法，属于拱桥施工技术领域，包括以下步骤：首先现场组拼钢梁节段，摆放时，钢梁节段的长度方向沿着桥梁的纵向；采用单个缆索吊将钢梁节段从现场运至桥中；利用提篮拱跨中侧边空隙将钢梁节段下放至运输船上，运输船掉头至钢梁待架设位置并调整钢梁节段的安装方向；然后采用两个缆索吊分别连接钢梁节段上的两个吊点，调整好安装角度后进行双机提升安装；钢梁节段施工完成，通过吊机完成桥面板的安装。本发明施工方法通过采用单个缆索吊将钢梁节段从现场运至桥中，运输船无需从陆地下水，由此解决了对于小跨度提篮拱桥的钢梁加工场无法进行水上运输时，钢梁吊装较为困难的问题。
