Description

[0002] At present, suction anchors are used as mooring devices for ocean engineering deep water mooring, and the suction anchor, also known as a suction bucket, is a cylindrical structure with an open bottom and a closed top, and a water pumping hole is arranged at the top of the bucket, which sinks and penetrates by self-weight and negative pressure formed after pumping, and bears the load of the upper structure after reaching the designated position. The installation of the suction anchor does not require special piling equipment, and the lightweight pump block construction is simple, which can adapt to deep water and ultra-deep water areas. With the same structure, if the load of the upper part is supported, it is also called a suction pile, which has the function of migration.

[0003] The suction bucket structure is generally more than 4m in diameter and more than 5m in height, and a steel plate with a thickness of more than 20mm is used for rolling, but the rolled steel plate needs a large-scale plate rolling machine, and the vertical ring lengthening or horizontal ring lengthening on site has the problem of difficult control of roundness, and the roundness measurement of large-size structure is also very difficult. If the roundness exceeds the standard, the suction bucket cannot be sunk to the designated position by negative pressure, and serious consequences such as oval deformation instability will occur. If the roundness is corrected, a strong steel manufacturing meter-shaped or H-shaped inner support is needed, and the installation and removal of the tooling will cause uncontrollable structural deformation. Therefore, how to reduce the deformation of the suction bucket and ensure that the installation requirements are met after manufacturing is a difficult problem in the manufacturing of the suction bucket.
