Abstract
First, a dredger digs some interval below the stem of the sunk boat. Then, a thin steel cable is threaded via the interval and is drawn back and forth by two towboats to expand the interval. After that, a thick steel cable is threaded via the interval. In this way, several thick steel cables are made to tie the sunk boat. The sunk boat is floated by several inflated drum tied to the thick steel cables. The salvaging method is simple and efficient.
Description
At present, domestic wreck salvage technology is to slip into the seabed by the diver earlier to find the shipwreck orientation, then makes a mark, again by diver's operation under water, silt below the shipwreck is dug out, under shipwreck, fastened some roads wirerope then, fixed the iron tympanites, water was arranged in the tympanites at per pass wirerope two ends, inflate draining after fastening, tympanites is under buoyancy function, and come-up emerges shipwreck, is dragged to required place then; This method, diver's operation under water for a long time, not only arduous, also dangerous, and bit by bit silt is scooped away under water by the diver, dig out some roads and pass the beneath through hole of hull, this work capacity is very heavy, often do not reach and dig through, because wind wave action, filled and led up again very soon, cause that all that has been achieved is spoiled, salvage a shipwreck in this way and often want some months even a few year, need expend a large amount of manpower and materials, get half the result with twice the effort.
The object of the present invention is to provide a kind of method of salvaging a sunken ship with wire hawser button method, this Refloatation method adopts operation at sea, no matter the water level depth, also no matter shipwreck tonnage size, as long as wire hawser can meet the demands, the people can salvage ship in water surface operation.
The present invention realizes that by following step this method comprises that the towboat of two band winchs, a dredger, a thick chain, two finer wire hawsers, some thicker wire hawsers, two sign ball floats, several big tympanites and steel weigh down; The sign ball float is used for indicating the water surface site of shipwreck head and the tail, and big tympanites is used for shipwreck is hauled out the water surface; Dig out by the silt of dredger earlier the bow bottom of shipwreck, expose some centimetres of bow bottoms, two towboats are positioned at shipwreck stern rear, distance is greater than shipwreck ship string width between two ships, article one, finer wire hawser two ends are positioned on the winch of two towboats, steel weighed down be tethered in the middle of the finer wire hawser, sink under water, by the diver it is enclosed within the gap, bottom of shipwreck bow, taking off steel weighs down, take turns dragsaw by the winch on two towboats, the finer wire hawser is pulled to hull bottom is a certain to be needed on the position, two towboats are by above shipwreck then, the distance of two towboats is still greater than the beam of shipwreck, wherein a towboat is fastened a end at the finer wire hawser with thick chain, another finer wire hawser is fastened the other end at thick chain, another towboat draws article one finer wire hawser in, thick chain is passed from the shipwreck bottom, be positioned at hull bottom, the winch of two towboats continues dragsaw in turn then, hull bottom is opened up out a space, thicker wire hawser one end is lain in the place that knots of article one finer wire hawser and thick chain, draw second finer wire hawser and thick chain in, thicker wire hawser setting fastening one end is passed under shipwreck, and setting fastening one end is not positioned at the original side of shipwreck, unties the thicker wire hawser, horizontal old in the shipwreck bottom, article one finer wire hawser is still reined in the shipwreck bottom; The continuation of two towboats is advanced to the shipwreck caudal directions and is cast anchor, and continues pulling finer wire hawser, repeats prior process, finally forms some thicker wire hawsers alow.
After adopting this method, alleviated diver's work capacity and danger greatly, the time of will salvaging simultaneously is by some months or foreshortened to tens days in several years, and required appropriate litigation fees is low, and thing half merit position is the simplest and the most direct in the wreck salvage work, successful method.
Be described in further details below in conjunction with drawings and the specific embodiments.
Fig. 1 is the scheme drawing of sign ball float of the present invention;
Fig. 2 is towboat of the present invention and dredger position view;
Fig. 3 is towboat of the present invention and thick chain position view;
Fig. 4 is the position view of thicker wire hawser of the present invention and iron tympanites;
As seen from Figure 1, dive into the water by the diver earlier, find out the head and the tail of shipwreck 1, fix sign ball float 2 and 3 then, sign ball float 2 and 3 is determined the position of shipwreck 1 on the water surface, dredger 9 is positioned at stem the place ahead of shipwreck 1, the shipwreck bow is indicated that promptly the silt under the ball float 3 digs out 10-20 centimetre, expose hull bottom, as shown in Figure 2, if the depth of water also can adopt explosive explosion under water, silt is blown, expose the hull bottom front portion, fasten the long finer wire hawser 5 of 20 millimeters of diameters between two towboats 6 and 7 and fasten respectively on the winch of two towboats 6 and 7, by the diver one steel is weighed down and fasten in the middle of the finer wire hawser, sink under water, be enclosed within shipwreck 1 and sink to the bottom the position of exposing, as shown in Figure 2; The steel bob is taken off, two towboats 6 and 7 are shifted to the shipwreck caudal directions, distance is greater than the beam of shipwreck 1 between two ships, with 5 tensions of finer wire hawser, make rope 5 and water surface angle at 45, shown in Figure 2, two ships 6 and 7 the winch pine and tight of taking turns then, drive finer wire hawser 5 dragsaw back and forth, finer wire hawser 5 is drawn in the bottom of shipwreck 1 rapidly, and two towboats 6 and 7 are drawn close to the top of shipwreck 1 then, two ships distance is still wide greater than the string of shipwreck 1, make finer wire hawser 1 be positioned at vertical plane surface, towboat 7 is fastened a end at finer wire hawser 5 with a thick chain 4, and another finer wire hawser 8 is fastened the other end at thick chain 4, towboat 6 draws finer wire hawser 5 in, thick chain 4 is passed from shipwreck 1 bottom, be positioned at hull bottom, the length of thick chain 4 should be greater than the twice of depositing in water, can both surface in so thick chain two ends, dragsaw is widened the hull bottom space, as shown in Figure 3 then; The coarse-wire rope 10 of a 60-100 millimeter is tied up to the place that knots of finer wire hawser 5 and thick chain 4, the length of thicker wire hawser 10 also should be greater than depth of water twice, towboat 7 draws finer wire hawser 8 in, pull an end of thicker wire hawser 10 setting fastenings into opposite side from the bottom of shipwreck 1, and setting fastening one end is not still stayed an original side, ship 7 is untied thicker wire hawser 10, then thicker wire hawser 10 is horizontal old in hull bottom, and the place of knotting of fine flexible steel wire 5 and thick chain 4 is positioned on the towboat 7, finer wire hawser 5 is still reined in the bottom at shipwreck 1, so far, article one thicker wire hawser 1 has been put on; Two towboats 6 and 7 are shifted to the rear of shipwreck 1 then, continue pulling finer wire hawser 5, repeat prior process, and another root thicker wire hawser 10 is crossed in the bottom of shipwreck 1; Go down successively, form some in the bottom of shipwreck 1 at last, shown in Figure 4; In whole work, the winch at finer wire hawser 5 two ends is action simultaneously always, and one of a pine is tight, and finer wire hawser 5 is tightly reined in shipwreck 1 bottom; By the diver water-filled iron tympanites 11 is fixed at some thicker wire hawser 10 two ends at last, water is discharged in inflation, then the iron tympanites tightly leans against on the ship string of shipwreck 1, under buoyancy function, some iron tympanites 11 emerge shipwreck 1, by towboat it is dragged to the predetermined area, fishing job is all finished.
Adopt this method to salvage one 500 tonnage carrier and one 800 tonnage barge at present.
