In-situ Bridge Placing Technology without Support for Small and Medium Bridges

中小桥无支架原位浇筑桥梁技术,在一定程度上简化了预制梁的预制、运、装等环节,有效降低施工成本,减少安全风险,缩短工期,在一定程度上是值得推广使用的。但又受限于应用条件,故此法多用于乡道、场内道路或者等级外公路等规模小的工程中,或条件相符的独立中小桥工程中,在高速和高等级公路施工中,一般桥梁工程规模较大,采用工厂化生产施工反而对施工质量和成本控制较为有利。

The technology of cast-in-situ bridge without support for medium and small bridges simplifies the precast,transport and installation of prefabricated beams to a certain extent,reduces construction costs,reduces safety risks and shortens construction period.To a certain extent,it is worth popularizing.However,it is limited by application conditions,so this method is mostly used in small-scale projects such as rural roads,on-site roads or off-grade highways,or in independent small and medium-sized bridge projects with matching conditions.Generally,in the construction of highway and high-grade highway,the scale of bridge projects is large.Instead,it is advantageous to the construction quality and cost control to adopt factory production construction.
