桶基平台负压沉贯施工机具的研究与应用

Study of the Machinery Equipment for Bucket Foundation Suction Penetration and Its Application in the Engineering

桶形基础采用负压沉贯方法施工 ,初始入泥和倾斜控制成为制约桶形基础平台应用于浅水区的重要环节。通过分析沉贯、倾斜调整机理 ,设计了 1种负压沉贯施工机具 ,并成功应用于CB2 0 B桶形基础平台的海上安装 ,对浅水区桶形基础平台施工机具研究开发具有指导意义。

If the suction penetration method is used for the bucket foundation construction, the initial penetration into mud and the inclination control become two main restrictive factors for the bucket foundation platform to be used in the shallow water area. Based on the analysis of the penetration and inclination adjustment mechanism, a machinery equipment for the suction penetration construction was designed and successfully applied in installing the CB20B bucket foundation platform at sea, which will be instructive to the development of the machinery equipment for bucket foundation platform suction penetration in the shallow water area.
