Description
Technical field
The present invention relates to a kind of armor, particularly about a kind of ocean composite soft tube tooth shape cross section resistance to compression armor.
Background technique
Traditional, conventional submarine pipeline is taking steel pipe as main, the construction, installation of entirety and follow-up maintenance work cycle, long expense was high, the flexible compound pipeline that Abroad in Recent Years rises because anticorrosive property is good, submarine topography landforms strong adaptability, laying speed is fast, expense is low, be difficult for wax deposition and the conveying that advantage starts to be applied to seabed oil, G&W such as can reuse comes up.Flexible compound pipeline comprises cohesiveencess composite soft tube and non-adhesive composite soft tube; Wherein, cohesiveencess composite soft tube is generally squeezed into one by polymeric layer and metal enhancement layer, after extrusion modling, makes the higher bonding strength of generation between polymer material layer and metal enhancement layer by special operation.Such flexible pipe is generally applied to short distance jumper pipe.Non-adhesive composite soft tube is to be combined by the mode of physics by polymer material layer and metal enhancement layer, and layer does not need to use chemical technology bonding with interlayer, and each interlayer carrys out transmitted load by friction and contact, and it is flexible better.Non-adhesive composite soft tube is generally used for the pipeline of long distance and high pressure and carries, and it is applied in ocean engineering more and more extensive to the conveying of crude oil or rock gas or water.Non-adhesive composite soft tube becomes the main flow structure in flexible pipe gradually, by framework layer, inside liner, resistance to compression armouring layer by layer, the composite pipe body structure that forms of the multilayer such as tension armor, external coating.Wherein resistance to compression armor mainly provides opposing radial force, and interlock formation by profile shapes, profile shapes has Z, C, X, T-shaped etc., resistance to compression armor becomes wide-angle to be entwined by profile shapes with tubular axis, winding angle is generally close to 90 degree, can provide larger circumferential force to press compared with imperial palace with opposing, inside liner is played to effect of contraction, prevent inside liner explosion.Resistance to compression armor has certain gap after being wound around between adjacent cross section, can ensure that like this flexible pipe has certain flexibility, and gap between adjacent sections is larger, the bending flexibility of this layer is better, but has also brought hidden danger simultaneously, because the increase in gap has caused the increase of its inside liner creep compliance, and in the time that bending is excessive or axial motion is excessive, motion between adjacent sections is excessive, has the possibility mutually skidding off between adjacent cross section, can cause the forfeiture of cross section interlocking function.
Summary of the invention
For the problems referred to above, the object of this invention is to provide a kind of can be in the situation that composite soft tube inside liner creep compliance be identical, strengthen the bending flexibility of resistance to compression armor, can effectively prevent the composite soft tube tooth shape cross section resistance to compression armor that resistance to compression armor adjacent sections skids off mutually simultaneously.
For achieving the above object, the present invention takes following technological scheme: a kind of composite soft tube tooth shape cross section resistance to compression armor, it is characterized in that: it adopts profile shapes to be wound around interlocking and forms, the Wei Yazhuan cross section, cross section of described profile shapes, this cross section comprises a girder, described girder comprises the first diapire and the second diapire along its length, the two ends of described the second diapire have been wholely set respectively an end dentation structure to the same side, be arranged at intervals with two middle part dentation structures on described the second diapire between two described end dentation structures; Described middle part dentation structure forms end sunk area between the described end dentation structure being adjacent; Between two described middle part dentation structures, form medial recess region; Two described end dentation structures are all to the same side bending, and include an outer side wall, a madial wall and an increment face; The outer side wall of described end dentation structure adopts arc angle of attachment to connect with being connected of the first diapire of described girder; The increment face of described end dentation structure connects with also all adopting arc angle of attachment being connected of described outer side wall and madial wall; The madial wall of described end dentation structure connects with also adopting arc angle of attachment being connected of the second diapire of described girder; Two described middle part dentation structures include two sidewalls and an increment face; The increment face of described middle part dentation structure adopts arc angle of attachment to connect with being connected of two described sidewalls; Two described sidewalls with being connected of the second diapire of described girder also adopt arc angle of attachment to connect; In the end sunk area of described profile shapes, insert the middle part dentation structure of an adjacent described profile shapes, and have certain interval; In the medial recess region of described profile shapes, insert the end dentation structure of two adjacent described profile shapes, and have certain interval; Adjacent described profile shapes is engaged.
