谈高速公路互通式立交桥连续梁现浇施工技术

On construction technique of cast-in-situ continuous beam of interchange overpasses along expressway

依托京新项目乌力吉互通A匝道桥连续梁工程实例,从支架搭设、模板安装、混凝土工程、预应力施工等方面,对高速公路互通式立交桥连续梁的施工工艺进行了阐述,通过采用该施工工艺,缩短了施工工期,节约了人员和机械设备的投入,取得了良好的经济及社会效益。

Based on the continuous beam of Uliji Interchange A Ramp Bridge of Jingxin Program,the paper illustrates the construction craft for the continuous beams at interchange overpass bridge along expressways from the support erection,installation of formwork,concrete projects,and prestressed construction,and indicates the construction craft can shorten the construction period,save the investment in personnel and mechanic equipment,so as to achieve better economic and social benefits.
