Abstract
The utility model discloses an offshore wind power rock-socketed single pile foundation, comprising a main body, an anti-collision component, a sacrificial anode, a lifting lug and an external platform, wherein the main body is a cylinder, the anti-collision component is arranged at the sea level of the surface of the main body, the sacrificial anode is arranged on the surface of the main body and is arranged under the sea level, the main body is provided with the lifting lug, and the main body above the sea level is provided with the external platform. The offshore wind power rock-socketed single pile foundation has the beneficial effects that a single pile foundation is arranged when rock exists, the process is optimized, and the construction cost is reduced greatly.
Description
Technical field
The utility model relates to the basic engineering of offshore wind farm industry, relates in particular to a kind of offshore wind farm embedding rock formula single pile basis.
Background technology
The intertidal zone is between the high and low tidal level of spring tide, the area that is submerged and exposes with tiding.According to preresearch estimates, the intertidal zone annual mean wind speed can reach the 6-7 meter per second, so possesses utilizable wind energy in the intertidal zone.For the intertidal belt wind electric engineering, it is mainly concerned with the construction on wind-powered electricity generation unit basis.
The maximum difference of Oversea wind power generation and land wind-power electricity generation is both residing positions; Because the basis of offshore wind farm unit is in the sea; Increased many extra load and uncertain factor, thereby design is comparatively complicated, form of structure is the variation owing to different sea situations also.What the fixed basis of offshore wind farm unit was the most frequently used has 3 kinds: single pile formula, gravity and triangle posture.Single pile formula basis is simple in structure and easy for installation because of it, is present commonplace form.But for the marine site that has thicker rock stratum, the requirement of use can not be satisfied in the conventional formula of squeezing into single pile basis.
Therefore, need provide a kind of offshore wind farm embedding rock formula single pile basis to address the above problem in the prior art.
The utility model content
In order to address this problem; The utility model discloses a kind of offshore wind farm embedding rock formula single pile basis; Said single pile basis comprises main body, crashproof member, sacrificial anode, hanger and outer platform, and said main body is a cylinder, and said crashproof member is arranged on the place, sea level on the surface of said main body; Said sacrificial anode is arranged on the surface of said main body; And it is arranged under the said sea level, and said main body is provided with said hanger, and the said main body on the said sea level is provided with said outer platform.
Preferably, said sacrificial anode is a polylith.
Preferably, between the said main body and batholith under the sea bed, and the set inside of said main body has the grout compartment.
Preferably, the external surface of said main body is provided with cable conduit and cat ladder.
The offshore wind farm embedding rock formula single pile basis of the utility model has solved the problem that the single pile basis is set when having the rock stratum, has optimized technology, has reduced construction cost greatly.
In the utility model content part, introduced the notion of a series of reduced forms, this will further explain in specific embodiment part.The utility model content part does not also mean that key feature and the essential features that will attempt to limit technical scheme required for protection, does not more mean that the protection domain of attempting to confirm technical scheme required for protection.
Below in conjunction with accompanying drawing, specify the advantage and the characteristic of the utility model.
Description of drawings
Fig. 1 is the sketch map according to the offshore wind farm embedding rock formula single pile basis of an embodiment of the utility model.
The specific embodiment
In the description hereinafter, provided a large amount of concrete details and the utility model has been understood more completely so that provide.Yet, it will be apparent to one skilled in the art that the utility model can need not one or more these details and be able to enforcement.In other example,, describe for technical characterictics more well known in the art for fear of obscuring with the utility model.
In order thoroughly to understand the utility model, detailed structure will be proposed in following description.Obviously, the execution of the utility model is not limited to the specific details that those skilled in the art has the knack of.The preferred embodiment of the utility model is described in detail as follows, yet except these were described in detail, the utility model can also have other embodiments.
Below in conjunction with accompanying drawing the embodiment of the utility model is done detailed description.
With reference to figure 1, be sketch map according to the offshore wind farm embedding rock formula single pile basis of an embodiment of the utility model.The single pile basis of the utility model comprises main body 1, crashproof member 2, sacrificial anode 3, hanger 4, outer platform 5.Wherein main body 1 is a cylinder, and crashproof member 2 is arranged on the surface of main body 1, and it is arranged near the sea level 11.Sacrificial anode 3 also is arranged on the surface of main body 1, and it is arranged under the sea level 11.Preferably, polylith sacrificial anode 3 can be set.On main body 1, also be provided with hanger 4, the single pile basis lifted with convenient.On the main body on the sea level 11 1, also be provided with outer platform 5.Cable conduit and cat ladder 7 can also be set on the external surface of main body 1.
Between main body under the sea bed 12 1 and batholith, and the inside of main body 1 also is provided with grout compartment 6, in order to the single pile basis is fixed.
When this single pile basis is set; At first adopt dredge boat to remove the mud on sea bed basement rock surface, utilize slewing drilling machine or percussive drill at the basement rock pore-forming, the diameter in this hole for example can be 5-6 rice; Dark 8-10 rice; Behind the pore-forming big single pile basis is sunk in the hole, and adjusted the pile body verticality simultaneously, and to utilizing the high-grade concrete cast in the stake and between pile body and the batholith.
The offshore wind farm embedding rock formula single pile basis of the utility model has solved the problem that the single pile basis is set when having the rock stratum, has optimized technology, has reduced construction cost greatly.
The utility model is illustrated through the foregoing description, but should be understood that, the foregoing description just is used for for example and illustrative purposes, but not is intended to the utility model is limited in the described scope of embodiments.It will be understood by those skilled in the art that in addition; The utility model is not limited to the foregoing description; Instruction according to the utility model can also be made more kinds of variants and modifications, and these variants and modifications all drop in the utility model scope required for protection.The protection domain of the utility model is defined by appended claims book and equivalent scope thereof.
