Description
Technical field
The present invention relates to raising of a wreck technical fields, connect and set more particularly to a kind of backing girder steel for salvaging a sunken ship
It is standby.The backing girder steel threading method that the invention further relates to a kind of for salvaging a sunken ship.
Background technique
Very heavy the key link during being shipwreck raising integrally is worn in seabed, generally takes up entire refloating operation underwater operation
50% or more of time.With the increase of depth, underwater operation risk is bigger, the underwater operation time is longer, to greatly increase
Salvaging difficulty and construction cost are added.
The key link of raising of a wreck is that shipwreck bottom connects cable wire or backing girder steel.Wherein, cable wire is connected due to only needing
Drilling smaller aperture due, difficulty of construction connect small compared with girder steel.Mainly connecting mode has direct mechanical presses method, high pressure water flushing at present
Brush method and underwater directing bore method, these connect the seabottom geology that mode is primarily adapted for use in weak earthing.Wherein, direct mechanical presses
Method and the high pressure water method of washing away need the underwater handheld tool operation of diver, and artificial underwater operation amount is big, the time is long, its efficiency
It is low, risk is big.
Although underwater directing, which bores method, can be realized sea operation, but steel beam structure size is big, mostly square from great, shape
Shape, so that Directional Drilling Technology be made to be difficult to dig heavy caliber through hole at deep-sea.Main use directly pulls method or high pressure water at present
It washes away auxiliary to pull, direct dragging method fastens stretching rope in girder steel head end, then directly pulls from joist export direction, is
Dilatory force is reduced, can be tapered, streamlined etc. by the design of joist end, and install cutting tool additional.High pressure water washes away auxiliary and pulls
It is that high-pressure water nozzle is set in joist front end, front earthing is washed away using high pressure water.However, the self weight of large-tonnage shipwreck is larger,
It is often compacted the sea bed in its region of sinking, causes the supporting zone soil condition of shipwreck bottom comparatively dense.It is existing to use steel
The direct pushing tow of beam is difficult to efficiently complete hole excavation by the way of high pressure water auxiliary flush, especially meets with local hard
It is unable to complete and connects when geological condition (such as lithostratigraphy), and girder steel can not accurately rectify a deviation.It is soft that these are still only applicable to seabed
Weak earthing substrate connects distance not long situation, and is difficult to connect under fine and close and hard geology.In addition, in large-tonnage shipwreck
During globality is salvaged (such as tjemplon, oil tanker), often size is bigger for matched backing girder steel, and girder steel is self-possessed under water
Bigger, movement and pose adjustment are more difficult.
Summary of the invention
For at least some technical problems as described above, the present invention is directed to propose a kind of backing steel for salvaging a sunken ship
Beam threading equipment.The propulsion of development machine in the backing girder steel threading equipment connects synchronous implementation, one-pass molding with backing girder steel.
Backing girder steel connects aperture, propulsion, guiding of underwater operation part etc. and is all made of mechanization remote operation, to make diving operation
Amount, underwater operation intensity are greatly reduced, and the security performance for greatly improving construction efficiency, improving construction is reduced and applied
Work cost.In addition, excavating backing girder steel by development machine connects cavern, excavation hole diameter is big, and it is real-time to excavate the direction promoted
Controllably.Meanwhile development machine can also excavate fine and close or hard geology by the way that the cutter being arranged on host is broken, and it is suitable to expand geology
