摘要
在公路改建和桥梁养护中,支座的更换改造已成为亟需解决的问题。本文从方案比选、施工准备工作、施工作业等方面简要介绍了无支架超薄型液压整体顶升更换支座法,以资借鉴。
How to change bridge abutments needs to be solved during road reconstruction and bridge maintenance. It is introduced for reference in this paper on the method of ultra-thin integral hydraulic jacking without support by schemes comparison, preparation and construction.
