摘要
南昌市某高架桥工程中钻孔灌注桩及墩柱钢筋连接采用直螺纹连接技术,接头质量稳定,大大加快了施工进度,节约了钢材,获得了良好的经济、社会效益。本文介绍了其工艺原理、工艺流程以及操作要点。
The straight thread connection technology is employed for the cast in-situ piling pile and pier column reinforcing bar connection in Nanchang-located a viaduct project. The connector is stable in quality, which greatly speeds up the construction sched- ule, saves steels and thus obtains remarkable economic benefits and social benefits. The process principle, process flow and operating rules are presented in this paper.
