Method for assembling large-section rectangular prefabricated box culvert
The invention relates to a large-section rectangular prefabricated box culvert assembling method which comprises the steps that (1) matched construction is adopted in rectangular box culvert prefabrication, and integral module subsection prefabrication is adopted; (2) a prefabricated rectangular box culvert is installed, polytetrafluoroethylene plates with various thicknesses are used for being lined on the foundation bottom face and the longitudinal joints of the prefabricated rectangular box culvert, and the perpendicularity and the elevation of the upper section and the lower section of theprefabricated rectangular box culvert are finely adjusted; and (3), longitudinal sections of the prefabricated box culvert are fastened through prestress, so that circular seams between the sectionsare tightly attached. the prefabricated box culvert construction method has the advantages that the matching precision is high, the construction is safe, the construction period of a construction siteis greatly shortened, and the problem that the traffic needs to be quickly recovered in the urban road box culvert construction is solved.
本发明涉及一种大断面矩形预制箱涵拼装方法，包括：1)矩形箱涵预制采用匹配施工，以及采用整体模块分段预制；2)预制矩形箱涵的安装，并利用各厚度四氟板衬垫于预制矩形箱涵的基础底面、纵缝处，微调预制矩形箱涵上下节段垂直度及标高；3)预制箱涵纵向节段采用预应力紧固，使节段间环缝密贴。本发明匹配精度高、施工安全、施工现场工期大幅缩短，解决城市道路箱涵施工需快速恢复交通的难题。
