Description

A kind of Refloatation method of marine shipwreck

One, technical field

The invention discloses a kind of Refloatation method of shipwreck, belong to marine wreck salvage field of engineering technology.

Two, background technology

The traditional wreck salvage method that generally adopts in current China salvage system mainly contains: batten down draws water, the draining of calming the anger, floating drum is lifted floating, crane barge is lifted the combination of floating or above method, stressed size can't accuracy control on each stress point of shipwreck for the tradition Refloatation method, the shipwreck unbalance stress causes longitudinal strength not meet the demands easily and causes the hull distortion, the uncontrollable steel rope that also causes easily of local pressure size is reined in the into situation of hull, and hoisting depth is uncontrollable in the floating process, because calm the anger with in the pump process, it is imponderable having produced the much buoyancy of lifting, and gas can expand in the floating process, ascending velocity when having quickened floating, cause the floating process more uncontrollable, its salvaging cycle is long, efficient is low, the cost height.

Two, summary of the invention

Purpose of the present invention is intended to overcome the deficiency of above-mentioned prior art, discloses a kind of operating efficiency height, salvages low, applied widely, the safe and reliable marine wreck salvage method of cost.

For achieving the above object, the present invention is achieved in that a kind of Refloatation method of marine shipwreck, its special character is, be to utilize many jacks whiles of computer controlled or the independent stressed shipwreck that promotes, be specially, arrange two barges in the shipwreck both sides, the steel rope of pocket being crossed the shipwreck hull bottom is connected adaptor union on the barge by the guide wheel bearing, the other end of adaptor union connects steel strand, steel strand couple together by reaction frame and jack, per two jacks connect a hydraulic power unit, hydraulic power unit on two barges is connected to computer control system jointly, afterwards, utilizes pretension to carry out pretension with the elevator system and the steel rope of jack pair per pass steel rope position, stressed and stroke to every jack in control system promotes or playback as required synchronously, to realize that lifting of shipwreck is floating or it is heavy to put.

The good effect that compared with the prior art the present invention has is, (1), broken through traditional fishing process, for wreck salvage provide a kind of and traditional handicraft than applied widely, reliability is high, safe, fireballing Refloatation method; (2), the wreck salvage engineering is brought in " digitalisation engineering " by traditional " fuzzy engineering ", traditional wreck salvage method, as raising with salvage pontoons, we can't know the stressed of every steel wire, can't accurately calculate and control the floading condition of shipwreck, even the buoyancy that provides of every floating drum what are all can't know, but let us of the present invention can be clear that the pulling force of each jack, promptly every steel wire is stressed.What is more important can be adjusted the stressed of any steel wire at any time, can adjust the displacement of every steel wire at any time, even can add on one ton of one ton of ground, and one ton of one ton of ground subtracts; Can one millimeter one draw in the least, can one millimeter one millimeter ground pine, but stressed accuracy control during salvaging, shipwreck hoisting depth may command; (3), greatly reduce diver's work capacity, thereby greatly reduce the work drowned security risk, make the work may command more that becomes, the duration is more secure, the work that this up-to-date technology need be finished many scripts under water " moves " and waterbornely comes.In the raising with salvage pontoons method, diver's lag pile under water is necessary, but in the current refloating operation, the connection of big steel wire has reduced diver's underwater operation amount but above deck, makes work become more controlled, and the duration is more secure; (4), fishing operation efficient improves greatly, with traditional Refloatation method relatively, efficient obviously improves, attack and elevator system install crossing by end steel rope for main time only use during salvaging, only needs especially during floating just could in about 1 day; (5), the salvaging cost is low; (6), it is big always to lift buoyancy, the crane barge maximum power of hanging can reach 5000 tons in the market, need up to ten thousand tons shipwreck obviously powerless for lifting buoyancy, and be subjected to the suspension hook quantity limitation, when arranging the floating steel rope, can run into bigger difficulty, and Refloatation method of the present invention is not subjected to the influence of these factors fully, and lifting the buoyancy size can increase arbitrarily by increasing elevator system, and the floating steel rope can be arranged arbitrarily as required.
