Method for erecting curved steel truss cable-stayed bridge
The invention provides an erection method of a curved steel truss cable-stayed bridge, and relates to the technical field of bridge erection, the erection method of the curved steel truss cable-stayed bridge comprises the following steps: installing two tower cranes, and installing a swivel system through the two tower cranes; symmetrically and synchronously hoisting pier top steel beams on the suspended splicing bracket through two tower cranes; symmetrically and synchronously hoisting a preset number of steel beam sections along the two sides of the pier top steel beam through two tower cranes, and synchronously mounting a preset number of steel tower sections above the pier top steel beam; two deck cranes are installed through the two tower cranes; and the remaining steel beam sections are symmetrically and synchronously hoisted through the two deck cranes, the remaining steel tower sections are synchronously installed above the pier top steel beams, and the stay cables at the corresponding positions are hung and tensioned when each steel beam section is hoisted. Compared with the prior art, tower and beam synchronous construction can be achieved, bridging equipment is fully utilized, and the erecting efficiency of the steel truss cable-stayed bridge is improved.
本发明提供了一种曲线钢桁斜拉桥的架设方法，涉及桥梁架设技术领域，曲线钢桁斜拉桥的架设方法包括安装两台塔吊，并且通过两台塔吊安装转体系统；通过两台塔吊在悬拼支架上对称同步吊装墩顶钢梁；通过两台塔吊沿墩顶钢梁两侧对称同步吊装预设数量的钢梁节段，并且在墩顶钢梁上方同步安装预设数量的钢塔节段；通过两台塔吊安装两台桥面吊机；通过两台桥面吊机对称同步吊装剩余钢梁节段，并且在墩顶钢梁上方同步安装剩余数量的钢塔节段，每吊装一个钢梁节段挂设相应位置的斜拉索并进行张拉。本发明相比于现有技术，可以塔梁同步施工，且架桥设备得到充分利用，提高了钢桁斜拉桥的架设效率。
