The purpose of this utility model provides the submerged wreck software of a kind of intensity height, easy to control, easy anchoring, convenient transportation, big 100 cubic meters of displacement and salvages air bag.

The purpose of this utility model realizes in the following manner, the profile that to make with rubber or polyamine fat elastic composite is oval lantern shape software air bag, be fixed on by upper cover, on the air bag core that low head is formed, reducing valve is installed on upper cover, inflation is chewed and hoisting ring, also reducing valve can be installed on the low head, inflation is chewed and hoisting ring, during use hoisting ring and shipwreck are anchored at together, the inflation chew with repair ship on Air compressor join, its effect is identical with salvage pontoon, but compare with the floating drum of the same row water yield, has volume little (when not inflating), in light weight, easily make, cost is low, easily transportation, withstanding corrosion, easy to store, easy to use, construction is fast, advantages such as safety of operation, especially construction is fast, low and the safety of operation of cost is the key that can shipwreck salvage construction.This software salvage air bag since when not inflating volume very little, a ship can load and transport tens simultaneously.
