Abstract

The invention discloses a self-elevating platform pile inserting device comprising a composite pile shoe and a method. The pile inserting device comprises a child pile shoe, the child pile shoe is arranged under a mother pile shoe, the child pile shoe is connected with the mother pile shoe through a pile leg, the pile leg is provided with a washing device, the washing device is provided with a nozzle, and the nozzle is arranged between the child pile shoe and the mother pile shoe. A filtering structure is arranged at the bottom of the washing device. According to the pile inserting device and method of the self-elevating platform, the large load generated in the positioning process of the pile shoe is effectively reduced, the design and manufacturing cost of the pile shoe is optimized, and meanwhile, compared with a conventional pile shoe device, the positioning capacity is greatly improved.

Description

technical field [0001] The invention relates to a self-elevating platform piling device and method with a composite spud can, and belongs to the technical field of ships and marine engineering. Background technique [0002] Generally speaking, during the migration process of the self-elevating platform, the mud needs to be discharged, and then the legs are lifted. After the migration is completed, the legs are lowered again, and the mud is discharged with spud shoes. [0003] In order to obtain a more reliable grip of the pile foundation, the jack-up platform generally deeps the spud cans into the hard mud layer. In the actual design process, considering the safety of the spud cans, the design is generally conservative, which greatly improves the On the other hand, due to the uncertainty of ocean currents, the pile legs are subject to multi-directional ocean current loads, and the grip of conventional spud cans is prone to failure under multi-directional ocean current loads,...
