地下连续墙刚性排插接头技术研究

Research on Rigid Plug⁃in Joint Technology of Underground Continuous Wall

通过研究地下连续墙钢筋笼和钢箱作为受力结构、钢箱与钢筋笼刚性连接、连接采用排插式方法等一系列施工技术研究实现刚性排插接头工艺,有效避免混凝土绕流,提高地下连续墙接头的止水效果及受力性能。研究结果表明,随着超大超深基坑的实施,刚性排插接头技术在大型工程中具有广泛应用的潜力。

By studying a series of construction techniques such as the steel cage and steel box of the underground continuous wall as the stress structure,the rigid connection between the steel box and the steel cage,and the connection using the row⁃type method,the rigid row⁃type joint process is realized,which effectively avoids the concrete flow and improves the water⁃stopping effect and stress performance of the underground continuous wall joint.The research results show that with the implementation of super⁃large and super⁃deep foundation excavation,the rigid joint technology has the potential to be widely used in large⁃scale projects.
