Technical Field
The invention relates to the field of sunken ship salvage, in particular to a method for integrally salvaging sunken ships by a bottom-supporting steel beam.
Background
In the salvaging construction of the marine sunken ship, the sunken ship is often in a turned over or lying state, and the salvaging difficulty is high as a whole due to the weakness of the ship side structure. Normally, the ship which is not sinking is integrally salvaged, and the ship needs to be wrenched first and then salvaged. However, in some special cases, the sunken ship lying on one side needs to be integrally salvaged so as not to damage the sunken ship.
In view of the weakness of the side structure, it is necessary to make a large-sized supporting steel beam for supporting the weight of the hull with the side, and to share the weight of the hull with the steel beam and to support the weight of the sunken ship with the steel beam. The method adopts steel beams to support the ship body, and the weight of the ship body is dispersed on one steel beam. The weight of the ship body is dispersed on a larger area, so that the local strength of the ship body is smaller, the ship body is better protected, and the damage to the structure of the ship body is avoided. Generally, steel beams which are well attached to the profile of the ship body are adopted for supporting the weight of the ship body of the sunken ship, hoisting eye plates are arranged at two ends of the steel beams, and fishing hoisting steel wire ropes are connected to the eye plates at two sides. And the sunken ship is integrally lifted to salvage out water through the lifting steel beam.
