Construction process of cable crane hoisting system
The invention discloses a construction process of a cable crane hoisting system, and belongs to the field of bridges. The construction process comprises the following steps of step (1), respectively carrying out the construction of foundation embedded parts of towers on both sides on transition piers on both sides of a bridge, and then assembling the towers on both sides and installing wind cableson the corresponding towers; step (2), installing cable saddles on the tops of the towers on both sides, and carrying out the construction of main anchors on both sides; step (3), installing a main bearing cable and installing a winch at the same time; step (4), carrying out the installation of a lifting trolley, a traction rope and a hoisting rope; and step (5), carrying out hoisting system inspection and trial hoisting. According to the scheme of the invention, the towers are erected on the tops of the bridge transition piers, the span of a cable system is reduced and the height of the towers is reduced; and the arrangement not only greatly saves the construction cost and speeds up the construction progress, but also ensures the construction safety of a cable crane used in a large-span,variable cross-section steel truss continuous rigid frame bridge, and the hoisting construction process is simple.
本发明公开了一种缆索吊机吊装系统的施工工艺，属于桥梁领域，其步骤为：（1）在桥梁两岸过渡墩上分别进行两岸塔架基础预埋件的施工，然后进行两岸塔架的拼装，并在相应塔架上安装风缆；（2）在两岸塔顶进行索鞍安装，并同时进行两岸主锚锭的施工；（3）进行主承重索安装并同时进行卷扬机的安装；（4）进行起重小车、牵引索、起重索的安装；（5）进行吊装系统检查并进行试吊，本方案中将塔架设于桥梁过渡墩的顶部，减少了缆索系统的跨度，降低了塔架的高度，此布置不仅大大的节约了施工成本，加快了施工进度，同时保障了索缆吊机应用于大跨径、变截面钢桁梁连续刚构桥中的施工安全，且该吊装施工过程简单。
