Background technology

Wind energy is just increasingly paid attention to as a kind of clean regenerative resource by countries in the world.Nearly ten years, it is 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 the shallow sea water nearer from seashore.But the support construction of most of marine windmill will be chronically at badly Marine environment in, the effects that 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 so as 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 serious threat 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 challenge being had much 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 Leading 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 basalt fibre for marine environment Steel reinforced concrete composite pillar.

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 basalt fibre steel reinforced concrete composite pillar for marine environment, including a core Cardioid steel concrete column 1, a basalt fibre pipe 2 and a basalt fiber tendons 3；

The Core Steel Reinforced Concrete 1 filling is adapted in basalt fibre pipe 2, makes Core Steel Reinforced Concrete 1 profound Military 2 operative constraint of rock fibre pipe, improves the bearing capacity ability of Core Steel Reinforced Concrete 1, while makes basalt fibre Pipe 2 is supported by Core Steel Reinforced Concrete 1, prevents basalt fibre pipe 2 from indent yield failure occurs, and improves basalt fibre pipe 2 stability bearing capacity；

Basalt fiber tendons 3 are paperwrapped in the outside wall surface of basalt fibre pipe 2 effectively to alleviate in marine environment in the shape of a spiral Vortex-induced vibration, while basalt fibre has that intensity is high, durability is good and the advantages of corrosion resistance, so as to improve the longevity of structure Life, so as to improve the service life of structure, above-mentioned spiral helicine design parameter is as follows：Screw pitch takes 5~17.5D, and a height of 0.15D of spiral shell~ 0.25D, wherein D represent the outer diameter of basalt fibre pipe.

Core Steel Reinforced Concrete 1 includes concrete column ontology 10 and is embedded in the shaped steel 11 that cross section therein is Y shape. Specifically, the shaped steel 11 includes identical first support plate 111 of size, the second support plate 112 and third support plate 113, first support plate 111st, the second support plate 112 and third support plate 113 are formed the cross section of the Y shape of shaped steel 11 with 120 degree of angle two-by-two.

The production method of the utility model is as follows：

(1) material prepares：By basalt fibre continuous winding on the mold of certain diameter, while add in polymerization gluing Agent after basalt tube forming, it from mold is unloaded, that is, basalt fibre pipe 2 has been made, to basalt fibre pipe 2 The inner surface and the outer surface carries out smooth processing.Basalt fiber tendons 3 are wrapped in outside basalt fibre pipe 2.

(2) shaped steel welds：First support plate 111, the second support plate 112 and third support plate 113 are welded with 120 degree of angle two-by-two Form the cross section of the Y shape of shaped steel 11.

(3) concreting：Shaped steel 11 is uprightly fixed, housing basalt fibre pipe 2.Mixing concrete is matched by design, Strength grade can be properly added water-reducing agent and mineral additive between C30-C40, to improve the anti-corrosion capability of concrete. Concrete is inserted between shaped steel 11 and basalt fibre pipe 2, and abundant vibration compacting, so as to form Core Steel Reinforced Concrete 1。

(4) concrete curing：It will make by 1 basalt fibre pipe 2 of shaped steel Core Steel Reinforced Concrete and basalt The composite component that fiber bar 3 is formed carries out maintenance processing according to concrete related specifications.

The preferred embodiment of the above, only the utility model, therefore the utility model implementation cannot be limited according to this Range, i.e., the equivalent changes and modifications made according to the utility model patent range and description all should still belong to this practicality It is novel cover in the range of.
