浅谈膜袋砂围堰的施工

Discussion on Construction of Membrane-bag Sand Cofferdam

膜袋砂围堰经过多年的发展,已经成为比较成熟的一项施工技术,该方法施工过程简单、工期短、造价低、取材方便,固结好之后的膜袋砂围堰堰体比较稳定,密实度高,沉降小,防浪效果好。比较适合沿海低海拔低水头、粉细砂资源丰富、容易开采运输的地区。该文根据膜袋砂围堰在珠海水利工程实际施工做简要概述,提出相关建议,可为膜袋砂围堰在沿海水利工程的设计施工应用提供借鉴。

Over years of development, membrane-bag sand cofferdam has become a mature construction technique with simple construction process, short construction period, low cost and easily-obtained materials. The consolidated membrane-bag sand cofferdam has high stability and compactness, little settlement and good wave-resistant effects. It is suitable for coastal areas with low altitude, low waterhead, rich fine sand resources and easy mining and transportation. This paper provides a brief overview of the actual construction of membrane-bag sand cofferdam in Zhuhai Water Conservancy Project and made some relevant suggestions, hoping to help the design and construction application of membrane-bag sand cofferdam in water conservancy projects in coastal areas.
