Background technique
At present, pipeline under the ocean usually adopts the outer structure that sets gradually anticorrosive coat, thermal insulation layer, external protection coating and concrete weighted coating of pipe in steel, and usually the degree of depth be 60 meters with interior diving zone use.Because what thermal insulation layer adopted in the said structure is rigid polyurethane foam, for obtaining comparatively desirable heat insulation effect, its density is generally 80～100kg/m
3, compressive strength 0.65～0.85Mpa.When the depth of water surpasses 60 meters, hydrostatic pressing can occur and be higher than the compressive strength of thermal insulating material own, the phenomenon that causes the thermal insulation layer foam structure to be crushed, thereby thermal conductivity raises, thermal insulation property reduces, and therefore, the monolayer heat-insulating pipe of said structure is not suitable for the depth of water to be used greater than 60 meters seabed.
In addition, if the hard polyurethane foams thermal insulation layer of said structure directly is exposed in the briny environment, form wet wadded jacket effect easily under hydraulic action, be embodied in the thermal insulation layer abscess into water that breaks, thermal conductivity raises rapidly, insulation failure.So the hard polyurethane foams thermal insulation layer of said structure can not directly contact with water, external protection coating must be set for it.
Simultaneously, because concrete weighted coating itself does not have waterproof action, so the hard polyurethane foams thermal insulation layer of said structure can not directly combine with concrete weighted coating, the external protection coating that band spirality cutting or rough surface need additionally be set combines with concrete.
The model utility content
To be solved in the utility model is seabed insulation counterweight conveyance conduit complex structure in the prior art, can only be applicable to 60 meters technical problems with interior diving zone, provide a kind of rational in infrastructure, make and simply, not to be with external protection coating, maximumly be suitable for a kind of ocean engineering that the depth of water can reach 3000m with wet type insulation counterweight conveyance conduit.
In order to solve the problems of the technologies described above, the utility model is achieved by following technological scheme:
A kind of ocean engineering is incubated the counterweight conveyance conduit with wet type, comprise the steel body, the outer surface of described steel body is coated with clinkery epoxy powder anticorrosive coat, wet type composite polyurethane elastic body heat preservation layer and concrete weighted coating successively, and described wet type composite polyurethane elastic body heat preservation layer is the polyurethane elastomer coating that is filled with hollow polymer microballon or hollow glass microbead.
