翼形接头管在地下连续墙码头的应用

Application of Wing Joint Pipe in the Underground Continuous Wall Wharf

集围护、防渗、承重等多重作用于一身的地下连续墙结构在港航、城市高层建筑、地铁等深基坑工程建设中发挥道重要作用,接头是地连墙质量相对薄弱的环节,对保证地连墙刚度、强度及防渗起着重要作用。本文以唐山港京唐港区26#~27#集装箱码头为例,通过翼形接头管的应用及水下探摸等技术手段验收手段,阐述其使用效果,以期对类似工程施工有一定的指导作用。

Underground continuous wall contains enclosure, anti-seepage and load-bearing＇s feature; it is the structure playing an important role in deep foundation excavation of port and waterway, urban high-rise buildings and metro construction. The joint of underground continuous wall is the relative weak part, which is the critical part for anti-seepage and stiffness＇ s prove. The following paper expounds the application of wing joint pipe in Tangshan Port Jing Tang District 26#~27# container berth. The acceptance of application effect is via underwater detection to guide the further project construction.
