Abstract
The invention relates to a submarine pipeline buckle arrestor with spiral side plates, belonging to the technical field of submarine pipeline facility laying. The submarine pipeline buckle arrestor is used for protecting a submarine pipeline and comprises two shells with identical size and structure, and each shell is a semicircular ring with a variable section. The two shells are both provided with eye plates stretching outward, and the eye plates are used for connecting the two shells through bolts. The outer diameter of each shell axially varies, the two shells are connected through a transition slope, two ends of the two shells are thick, the middle parts of the two shells are thin, and the external surfaces of the middle parts of the shells are fixedly provided with spiral side plates. After the two shells are connected into a circular column with a variable section, the spiral side plates in the middle parts are mutually engaged to form a spiral structure. Meanwhile, the invention also relates to a fixing method of the buckle arrestor. The buckle arrestor can effectively prevent the propagation of buckles of the submarine pipeline, ensures the integrity of the integral submarine pipeline and also greatly reduces economic losses caused by structural damages due to local buckles of the submarine pipeline.

Technical field
The invention belongs to the technical field in the submarine pipeline facility process of deployment, be specifically related to a kind of device that can effectively prevent the propagation of submarine pipeline flexing and suppress the vortex-induced vibration of pipeline.
Background technique
At sea in the process of deployment, the pipeline between pipe laying barge and the seabed exists one section quite long suspended span to submarine pipeline usually, and the length of suspended span is not only relevant with the depth of water, and is subjected to the influence of laying construction load and various complex environments.Can be subjected to some obstacle in the pipe laying process makes pipeline produce excessive bending deflection; After pipe laying is finished, because other external force effects such as collision of falling objects such as anchor and sea bed produce cripling equally.This cripling is in case take place, because of the effect that is subjected to outside hydrostatic pressure easily along the vertical bamboo telegraph of pipeline, finally cause the overall structure inefficacy of pipeline, seriously hinder pipeline and move normally.
In addition, undersea pipe-laying is in uneven sea bed surface, and under the acting in conjunction of factors such as ocean current, morning and evening tides, some zone on the laying route of pipeline pipeline takes place easily is exposed on the ocean bottom soil and forms unsettled section.Under the long term of environmental load, unsettled section easily come-up or lateral buckling and vortex-induced vibration takes place and lost efficacy.
Therefore, the buckle propagation of submarine pipeline and vortex-induced vibration bring enormous economic loss to the exploitation of offshore oil and rock gas, prevent that buckle propagation and vortex-induced vibration from having great importance for submarine pipeline engineering.
Usually take to buckle into modes such as cylindrical steel ring or winding around and reach the anti-bend effect at pipeline external surface.But shortcomings such as the ubiquity consumptive material is many, cost is high, construction process complexity.The method that suppresses vortex-induced vibration by peripheral hardware large volume flow guide device has increased construction cost, has improved the laying difficulty of pipeline simultaneously.At present, also not integrating the device that prevents buckle propagation and suppress vortex-induced vibration occurs.
Summary of the invention
The objective of the invention is to overcome the deficiency on the prior art, provide and effectively to prevent buckle propagation and the device that suppresses vortex-induced vibration, and provide a kind of making of this device and the method for on submarine pipeline, installing, take proper construction technology, reduce cost, effectively the buckle propagation and the vortex-induced vibration of control submarine pipeline are realized the unification of Economy and Security.
The technical solution used in the present invention is as follows: a kind of submarine pipeline buckle arrestor with the spiral side plate; be used to protect submarine pipeline; comprise two housings that size is identical with structure; each housing is respectively the semi-round ring shape of variable cross section; two housings all are provided with overhanging eye plate; described eye plate is used for connecting two housings by bolt; external diameter changes vertically and connects by crossing the inclined-plane; two ends are thicker; the middle part is thinner; housing middle part outer surface is fixed with the spiral side plate, and after two housings connected into the circular cylinder of a variable cross section, the spiral side plate at middle part coincide mutually and forms same helix structure.
As preferred implementation, the internal diameter of described two housings is got the external diameter of described submarine pipeline, length is got 1.5-2 doubly to described submarine pipeline external diameter, the thickness of two end portions or get 2.5-3.5 doubly to the wall thickness of described submarine pipeline is perhaps chosen according to the thickness of the outer concrete weighted coating of described submarine pipeline; The thickness at housing middle part is got the doubly wall thickness of the submarine pipeline of protecting of 1-1.5, and the height of spiral side plate is got the height on transition inclined-plane.
The present invention provides a kind of fixation method of above-mentioned submarine pipeline buckle arrestor simultaneously, comprise the following steps: a housing is close on the pipe surface, according to the identical mode consistent in eye plate position it is docked with another housing, pass eye plate by bolt then two housings are fixed on the pipeline with the sense of rotation of spiral side plate.
The invention provides a kind of device that prevents the submarine pipeline buckle propagation and suppress vortex-induced vibration, have the following advantages for existing technology: (1) the present invention can effectively prevent the propagation after the submarine pipeline generation flexing, guarantee the integrity of submarine pipeline integral body, keep away and reduce greatly that submarine pipeline causes structural damage by cripling and the economic loss that causes.(2) be provided with the spiral side plate at the buckle arrestor intermediate portion, when the come-up flexing took place submarine pipeline, buckle arrestor can apply certain disturbance and change reynolds' number when preventing buckle propagation to incoming flow, make flowing state enter turbulence state in advance, reach the effect that suppresses vortex-induced vibration.(3) every lobe hull shape of buckle arrestor is identical, can produce in batches by a mould, has simplified manufacturing process, has reduced manufacture cost.(4) do not influencing under the prerequisite that prevents buckle propagation effect and inhibition vortex-induced vibration, the buckle arrestor intermediate portion to lower recess, can be saved rolled steel dosage by chamfered transition like this, reaches economically viable effect.(5) mounting process of buckle arrestor is simple, can install by production line, increases work efficiency, and reduces construction cost.
