摘　　要：介绍了地下连续墙"Ⅱ"型接头的设计方法、施工技术及相关技术措施,并应用于工程实例。工程中"Ⅱ"型接头与地下连续墙槽段分开施工,提高了新型接头地下连续墙的施工效率。"Ⅱ"型接头保留了工字钢接头绕流路径较长的优点,使得地下连续墙槽段连接处防渗性能较好。槽段全部按照闭合幅施工,地下连续墙的施工质量得到了保证,一定程度上克服了钢筋笼下放时易出现的卡笼现象。This paper mainly introduces the design guideline, construction techniques, relevant counter measures and an engineering application of Ⅱ-type joint of diap of joint can be separated from panels which improves the wall＇ hragm wall. The new construction method s efficiency of construction. The new type joint retains the advantage of a long flow path which makes the wall a good seepage performance. The new construction method ensures each panel of the diaphragm wall constructed as a closed panel which overcomes the reinforcing cage jammed when it lowered.
