Construction method of large-span cable-stayed bridge
The invention discloses a construction method of a large-span cable-stayed bridge, and belongs to the technical field of cable-stayed bridge construction. Vertically rotating the steel arch tower; wherein the step of vertically rotating the steel arch tower comprises a step of vertically rotating the steel arch tower; mounting a vertical rotating platform, mounting a vertical rotating tower frame, assembling the steel arch tower, and rotating the steel arch tower; wherein the steel arch towers are arranged on the two sides of the vertical rotating tower frame and are symmetrically arranged relative to the vertical rotating tower frame, vertical rotating oil cylinder sets are arranged on the vertical rotating tower frame, and the vertical rotating oil cylinder sets are symmetrically arranged relative to the vertical rotating tower frame; and the vertical rotating oil cylinder group is connected with the steel arch tower through a rotating cable. The technical problems that due to the fact that the two sets of steel arch towers are vertically rotated in place, the vertical rotation efficiency is low, and safety accidents are likely to happen due to uneven tower stress are solved, and the technical effects that the steel arch towers are synchronously and vertically rotated on the two sides of the vertical rotation tower, and the vertical rotation oil cylinders work cooperatively to improve safety are achieved.
本发明公开了一种大跨径斜拉桥的施工方法，属于斜拉桥施工技术领域，包括以下步骤：主梁施工；以及钢拱塔竖转；其中，所述钢拱塔竖转步骤包括；竖转平台安装，竖转塔架安装，钢拱塔拼装，以及钢拱塔转体；其中，所述钢拱塔设于竖转塔架的两侧且关于所述竖转塔架对称设置，所述竖转塔架上设有竖转油缸组，所述竖转油缸组关于所述竖转塔架对称设置；所述竖转油缸组经转体索与钢拱塔相连。本发明解决了分别将两组钢拱塔竖转到位导致竖转效率低以及因塔架受力不均易引发安全事故的技术问题，实现了将钢拱塔在竖转塔架的两侧同步进行竖转以及使竖转油缸协同进行工作以提高安全性的技术效果。
