公路分离立交桥整体升高施工要点

Construction Points of Higher Separation Highway Overpasses the Overall

随着社会的进步及更多新材料、新工艺的出现,在提高质量的同时又减少了投资。而桥梁顶升技术就是其中一项成熟的科技含量较高的施工工艺。该技术的最大优点是缩短施工周期,避免重复投资,具有良好的社会和经济效应。论文通过桥梁顶升工艺解决桥下净空不足的问题,通过设置反力系统、限位系统、顶升施力系统和监测系统对梁体整体进行顶升。

With the progress of the society, more new materials and new processes appear, while improving the quality and reducing the investment. And the bridge top liR tecimoingy is one of the mature technology content high construction technology. The best advantage of this technique is to shorten the construction period and avoid repeated investment, which has good social and economic effects. This paper is to solve the problem of shortage of clearance under bridge by lifting technology of bridge, and the overall lifting ofbeem body is carried out by setting the anti-force system, the limit system, the top lift force system and the monitoring system.
