斐济瑞瓦河供水工程取水口钢板桩围堰施工技术

Construction Technology of Steel Sheet Pile Cofferdam at the Intake of the Rewa River Water Supply Project in Fiji

钢板桩围堰因其具有施工快捷方便、防渗效果良好等优点,已被广泛应用于水中围堰施工。钢板桩作为一种临时支护结构通过一定的咬合连接措施使其抗弯强度符合设计要求,与围堰共同作用形成围挡结构,对其应用情况进行研究具有重要的意义。以斐济瑞瓦河供水工程取水口钢板桩围堰施工为例对钢板桩围堰的设计与施工进行了探讨。

The steel sheet pile cofferdam has been widely used in water cofferdam construction because of its advantages of quick and convenient construction and good anti-seepage effect.As a temporary supporting structure,the steel sheet pile can make the bending strength meet the design requirements through certain joint measures,and form the enclosure structure together with the cofferdam.It is of great significance to study its application.Take as an example the construction of steel sheet pile cofferdam at the intake of the water supply project of Rewa River in Fiji,this paper discusses the design and construction of steel sheet pile cofferdam.
