Abstract

The invention discloses a salvage method based on underwater welding, which belongs to the technical field of salvage. The salvage method adopts the welding of a stressed eye plate on the hull of an underwater sunken ship, and connects the lifting steel wire with the stressed eye plate. The hoisting wire lifts the wreck out of the water. The method avoids the low-efficiency and difficult-to-construction link of the existing shipwreck salvage method running through the sunken ship, and can realize the salvage task of any sea bottom quality. In addition, for underwater sunken ships that are not sitting upright, this method can realize underwater straightening operations. Therefore, this salvage method has less requirements on the attitude of underwater shipwrecks, and has a wider range of applications in the salvage industry. The application of this technology can Significantly reduce the salvage cost and shorten the salvage period.

Description

technical field

[0001] The present invention relates to the technical field of salvage, in particular, the present invention relates to a salvage method based on underwater welding. Background technique

[0002] The traditional salvage method is to achieve the purpose of salvage by threading the salvage jack at the bottom of the shipwreck. For a long time, breaking through the jack has been the most influential construction link in salvage construction. Recently, through unremitting efforts in industry and colleges and universities, batch after batch of mechanical equipment for breaking through jacks has been developed. However, for complex seabed bottoms, related equipment has great limitations, especially for hard seabeds, the existing jacking equipment cannot effectively deal with it.

[0003] The weld quality and reliability of the traditional underwater wet welding method are not high, and it is not suitable for the welding of underwater stress components. With the d...
