Rapid construction method for municipal flyover
The invention relates to the technical field of municipal traffic engineering, and discloses a rapid construction method of a municipal flyover. According to the rapid construction method of the municipal flyover, the main bridge section is constructed firstly, and the approach bridge section is constructed later for coordinated construction. The steel box girders and the concrete box girders are prefabricated without on-site formwork pouring forming, the pouring process and the forming time are reduced, the construction progress is fast, and the construction period is short; waste caused by difficult recovery of excessive consumables during on-site formwork pouring is avoided, and the construction cost is reduced; the prefabricated steel box girder and the prefabricated concrete box girder are installed on the main bridge section concrete cover beam and the approach bridge section concrete cover beam through a movable crane in the mode that the front section and the rear section are oppositely hoisted, the movable construction hoisting area is wide, the construction difficulty is low, and the safety is high.
本发明涉及市政交通工程技术领域，公开了一种市政立交桥快速施工方法。本申请的市政立交桥快速施工方法，采用主桥段先施工，引桥段后施工方式协调施工。钢箱梁和砼箱梁均采用预制方式无需现场支模浇灌成型，减少浇灌过程和成型时间，施工进度快工期短；避免现场支模浇灌过多耗材不易回收造成浪费，降低施工成本；用可移动式吊车将预制钢箱梁和预制砼箱梁采用前后段对吊的方法分别安装在主桥段砼盖梁上和引桥段砼盖梁上，移动施工吊装区域广阔，施工难度低安全性高。
