文章结合某高速公路L1、L2、L4三座连续空心板梁互通式立交桥的支座更换施工为例,介绍小型千斤顶顶升桥梁上构进行支座更换时的施工步骤及施工工艺,为今后类似工程提供参考。
Taking the bearing replacement for continuous hollow slab beam interchanges L_1,L_2 and L_4 on one expressway as an example,the article introduces the construction procedure and process of bearing replacement with the superstructure lift by small jack,which provides reference for subsequent similar works.
