摘要
结合兰州新区新建大口径(3 m)钢波纹管安装雨水管道工程,介绍了管道的施工流程,对其挖基、施工放样、基础垫层的填筑、管道拼接涂刷沥青、打密封胶以及管道回填等管道拼装的关键技术进行了阐述,可为类似工程提供借鉴.
According to rainwater pipeline installation with large diameter(3 m)steel corrugated pipe in the Lanzhou New District,the paper reflected the convenience of steel corrugated pipe installation process,and introduced some key technologies including digging—foundation,lofting,filling the cushion,splicing pipeline,coating asphalt,sealant and pipeline backfill.It could provide reference for the similar engineering.
