Description
Technical field
The utility model is specifically related to a kind of epoxy resin carbon steel concrete composite pillar for marine environment.
Background technique
Wind energy is as a kind of clean renewable energy, the just attention increasingly by countries in the world.Nearly ten years, global
Annual installed capacity of wind-driven power rate of rise is 20%-30%, and world's wind-powered electricity generation is just developed with swift and violent speed.It is guided in national policy
Under, China's Oversea wind power generation is also widely used and develops, and total installation of generating capacity has ranked first in the world.Sea turn at present
Power machine is mostly deployed in from the closer shallow sea water of seashore.But the support construction of most of marine windmill will be chronically at badly
Marine environment in, the effects of bearing complicated sea, wave, stream.The long-term period effects of these load and the coupling between them
Effect is closed, the vibration of structure can be caused to reduce the fatigue life of structure, in some instances it may even be possible to cause sea turn motor significantly
Movement directly results in structure destruction, can bring and seriously threaten to the safe and reliable operation of wind energy conversion system, need to give and pay close attention to.
Vortex-induced vibration is the principal element that sea turn motor structural fatigue destroys all the time, and extra large for a long time
One of the problem of having much challenge in foreign engineering.With the increase of the depth of water, it is tight that the vortex-induced vibration problem of structure becomes more acute
Can lead to wind energy conversion system unstability, collapsing for weight, causes heavy losses.
Utility model content
The purpose of the utility model is to overcome prior art defects, provide a kind of epoxy resin carbon for marine environment
Plain steel concrete composite pillar.
The specific technical solution of the utility model is as follows:
A kind of epoxy resin carbon steel concrete composite pillar for marine environment, including a core concrete column, one
Carbon steel tubing and an epoxy resin pipe；
Core concrete column filling adapts in carbon steel tubing, makes core concrete column by carbon steel tubing operative constraint,
The bearing capacity ability of core concrete is improved, while supports carbon steel tubing by core concrete column, prevents carbon steel
Indent yield failure occurs for pipe, improves the stability bearing capacity of carbon steel tubing；
Epoxy resin pipe is paperwrapped in the outside wall surface of carbon steel tubing in the shape of a spiral and is impulsed with the whirlpool being effectively relieved in marine environment
It is dynamic.
The beneficial effects of the utility model are: the utility model includes a core concrete column, a carbon steel tubing and a ring
Oxygen pitch tube can be effectively relieved the vortex-induced vibration in ocean, have compared to the component of existing marine windmill support construction
Economic and corrosion resistant advantage.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the cross-sectional view of the utility model.
Specific embodiment
The technical solution of the utility model is further detailed below by way of specific embodiment combination attached drawing and
Description.
As illustrated in fig. 1 and 2, a kind of epoxy resin carbon steel concrete composite pillar for marine environment, including a core
Heart concrete column 1, a carbon steel tubing 2 and an epoxy resin pipe 3；
The core concrete column 1 filling adapts in carbon steel tubing 2, keeps core concrete column 1 effective about by carbon steel tubing 2
Beam, improves the bearing capacity ability of core core concrete column 1, while making carbon steel tubing 2 by 1, core concrete column
Support prevents carbon steel tubing 2 from indent yield failure occurs, and improves the stability bearing capacity of carbon steel tubing 2, wherein the material of carbon steel tubing 2
Matter specification is Q235；
Swash in the whirlpool that epoxy resin pipe 3 is paperwrapped in the outside wall surface of carbon steel tubing 2 in the shape of a spiral to be effectively relieved in marine environment
Vibration, screw pitch take 5~17.5D, a height of 0.15D~0.25D of spiral shell, and wherein D indicates the outer diameter of carbon steel tubing, while epoxy resin pipe
With preferable corrosion resistance, to improve the service life of structure.
The utility model the production method is as follows:
(1) material prepares: the carbon steel tubing of different specifications and helical form epoxy resin pipe are cut to identical set
Length is counted, respectively as carbon steel tubing 2 and surface layer helical form epoxy resin pipe 3.The wherein outer surface of carbon steel tubing 2 and surface layer spiral shell
The inner surface for revolving shape epoxy resin pipe 3 carries out smooth processing.
(2) casing is handled: surface layer helical form epoxy resin pipe 3 is inserted in carbon steel tubing 2, surface layer epoxy resin pipe and internal layer
It is bonded between carbon steel tubing with adhesive, to form multiple tube.
(3) plastic processing is compound: carrying out temperature-room type plasticity processing processing, plastic processing as early as possible after casing processing is completed
When total wall thickness reduction between 20%~80%, rolling pass subtracts as needed for 1~6 passage, the wall thickness of last a time
Thin rate is 10%, and plastic processing tup angle of feed is 90 °, and discharging speed is between 1~5m/min.
(4) finishing is handled, and the tube surfaces after plastic processing can generate many rough hammerings, therefore apply 1
Drawing of the gage variation during a pass reduction between 5%~25% improves the dimensional accuracy and surface quality of tubing；Most afterwards through inside and outside
Surface clean, cutting head cutting tail obtain multiple tube finished product.
(5) concreting: by design proportion mixing concrete, so that the intensity of concrete between C30-C40, can fit
When adding water-reducing agent and mineral additive, to enhance the anti-corrosion capability of concrete.Concrete is inserted carbon by upright multiple tube
2 inside of steel pipe, and abundant vibration compacting, to form core concrete column 1.
(6) it concrete curing: will make by core concrete column 1, carbon steel tubing 2 and surface layer helical form epoxy resin
The composite component that pipe 3 is constituted carries out maintenance processing according to concrete related specifications.
The above, the only preferred embodiment of the utility model, therefore, it cannot be limited according to, and the utility model is implemented
Range, i.e., equivalent changes and modifications made according to the scope of the patent of the utility model and the content of the manual should still belong to practical
It is novel cover in the range of.
