Abstract
Box culverts are common small structures in highway engineering. According to domestic and foreign practical experience in recent years, component factory prefabrication combined with on-site assembly can effectively improve production efficiency and construction quality. It will become the main trend in the box culvert structure and gradually replace the traditional cast-in-place process. Based on the project of 03A design section of Daqing to Guangzhou Expressway, this paper expounds in detail the assembly process and key operation points of prefabricated components. It also compared with the traditional culvert construction technique, which demonstrates the superiority of prefabricated box culvert assembly technology.
