Embodiment Construction

[0032] Below with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the role and working principle of the various parts, etc., will be further described. detailed description of the .

[0033] Such as Figure 1-4 Shown, this salvage method comprises the following steps:

[0034] (1) Explore the situation of the sunken ship 1, and clean up the surrounding obstacles that hinder the salvage of the sunken ship 1;

[0035] (2) ROV or diving survey the structure of the pre-welded position of the hoisting eye plate on the sunken ship, and conduct analysis and evaluation to determine the welding position;

[0036] (3) if figure 1 As shown, arrange the eye plate to be welded on the underwater dry welding equipment, lower the dry welding equipment 2, weld the eye plate 3 on the pre-designed position, ...

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...
