Description

Technical Field

[0001] The utility model relates to the technical field of marine engineering construction, in particular to a modular pile leg quick fixing tool. Background Art

[0002] In an offshore engineering platform, the role of the pile legs is to support the offshore engineering platform. As offshore engineering develops into deeper waters, during the use of the pile legs, it may happen that the original pile legs can no longer meet the depth requirements of the ocean. Currently, when replacing longer pile legs, the entire pile leg is usually replaced directly. The replacement cost and manufacturing cost of the pile legs are too high, and the process is more time-consuming and inefficient, which cannot meet the needs of offshore engineering.

[0003] At present, modular assembly pile leg technology is used to extend the length of the pile legs. For example, Chinese Patent Publication (Announcement) No. CN115627806A discloses a pile leg lengthening process, which is a method of obtaining a combined pile leg by cutting the original pile leg and docking and welding it with the new pile leg to be lengthened. Although the above method can extend the length of the pile leg to a certain extent, the need to cut the original pile leg affects the original installation stability and self-strength of the original pile leg to a certain extent. This undoubtedly increases the workload of the pile leg extension and the self-strength quality, making it impossible to achieve rapid installation, and cannot effectively reduce construction costs and improve the economy and applicability of the pile leg.
