Construction method of cable-first and beam-second segment hoisting self-anchored suspension bridge
The invention discloses a construction method of a cable-first and beam-second segment hoisting self-anchored suspension bridge. The construction method comprises the following steps: firstly, constructing a bridge tower and a transition pier, and erecting a side span full framing and a temporary pier; erecting side span stiffening beams on the full framing and the temporary pier and connecting into a whole, and installing temporary connecting structures between the side span stiffening beams and the bridge tower; erecting a main beam and a sling; hoisting mid-span stiffening beams, and connecting the mid-span stiffening beams into a whole after hoisting is completed; and carrying out system conversion, and completing follow-up construction of the self-anchored suspension bridge. According to the construction method, operation is easy and convenient, monitoring is facilitated, a main beam is installed based on an unstressed state, multiple construction schemes can be derived, the advantages of the large-span self-anchored suspension bridge with a underbridge navigation requirement can be brought into play, and the problem that temporary navigation cannot be achieved due to support method construction is solved; and compared with a traditional beam-first and cable-second method, the cable-first and beam-second segment hoisting self-anchored suspension bridge is simple and easy to construct, and the competitiveness of the large-span self-anchored suspension bridge can be further improved.
本发明公开了一种先缆后梁的节段吊装自锚式悬索桥施工方法，首先施工桥塔、过渡墩，搭设边跨满堂支架和临时墩；将边跨加劲梁架设至满堂支架以及临时墩上，并连成整体，安装边跨加劲梁与桥塔之间的临时连接构造；架设主梁，吊索；吊装中跨加劲梁，吊装完成后连成整体；体系转换，完成自锚式悬索桥后续施工。本发明施工方法操作简便、利于监控，基于无应力状态安装主梁，可衍生出多种施工方案，有利于发挥大跨度、有桥下通航要求的自锚式悬索桥的优势，解决了因支架法施工导致的无法临时通航问题；与传统先梁后缆法相比，本发明先缆后梁的节段吊装自锚式悬索桥施工简单易行，可以进一步提升大跨度自锚式悬索桥的竞争力。
