公路工程桥梁下部结构装配化施工技术

Fabricated construction technology of bridge substructure in highway engineering

以金丽温高速公路东延线桥梁下部结构预制拼装工程为例,主要介绍了桥梁下部结构预制拼装技术在公路工程中的实际应用,主要包含构件预制、进场安装,过程控制要点,关键工序以及全产业链发展前景,并与传统现浇混凝土施工作了简要对比。

Taking the prefabrication and assembly project of bridge substructure on the East extension line of Jinliwen expressway as an example, this paper mainly introduces the application of bridge substructure precast assembly technology in highway engineering, mainly including component prefabrication, approach installation, process control points, key processes and the whole industry chain Prospects. A brief comparison with the traditional cast-in-place concrete construction work is also presented.
