围堰防渗墙技术在港口干施工中的应用

Application of Diaphragm Wall Structure & Cofferdam in Dry Construction of Marine Port

介绍了围堰防渗墙技术在汉班托塔海港工程中的应用情况,从施工、监测方面详细论述采用围堰防渗墙围成基坑形成干作业环境后,在基坑内开挖港池,建造码头形成大海港的全过程。围堰防渗墙工艺在该港的成功应用,说明了干施工建造海港是可行的,为以后应用该工艺提供了借鉴。

This article introduces the construction technology of diaphragm wall structure ＆ cofferdam for application in Hambantota Port and discusses in detail in terms of construction, monitoring. The port applies diaphragm wall structure ＆ cof- ferdam to form dry construction condition. Basin excavation and pier building form marine port in the dry foundation. Under the condition, the marine port makes a great success. Dry construction is feasible to the construction of marine port and pro- vides a reference for future applications of the technology.
