摘要
针对复杂地况、超大水深充填袋围堰施工问题,阐述围堰袋体定位、充填、下沉控制工艺。采用打设钢管桩、定位充填袋、水下吹填施工工艺,在曹妃甸煤码头工程中完成平均水深20 m、长度150 m的围堰施工,为类似工程提供借鉴。
Aiming at the problem of complicated conditions and ultra deep water filling bag cofferdam construction, this paper introduces bag body positioning, cofferdam filling and subsidence control technology. Using design of steel pipe pile positioning, positioning water filling bag, underwater filling process, it is completed the cofferdam construction with an average depth of 20 m and 150 m in length in Caofeidian coal terminal project, which can provide the reference for the similar engineering construction.
