Description
Technical field
The utility model relates to wind generator facility, particularly a kind of offshore wind turbine steel work basis.
Background technology
Wind-power electricity generation is a green energy resource technology with fastest developing speed in the world, landwid electric field build fast-developing in, it has been observed that some restrictions that the land Wind Power Utilization is suffered, problems such as, noise pollution big as floor space.Oversea wind aboundresources, Oversea wind power generation are influenced by noise, birds and the less-restrictive of problem such as Electromagnetic Interference, and it does not take land land resources, does not relate to problems such as land acquisition.Have, the variation of marine wind speed with altitude is less again, does not therefore need to set up very high support tower, thereby can reduce the cost of offshore wind generating group.Also have, marine turbulence intensity is low, and sea level frictional force is less, and the fatigue load that acts on the wind power generating set reduces, thereby can prolong the application life of wind-powered electricity generation unit.
Because above plurality of advantages, the ocean will become a wind-power market that develops rapidly.Deposits in Eastern Coastal China depth of water 50m is vast with interior oceanic area, and it is very near apart from power load center (the flourishing power shortages of coastal economy district), full-fledged along with the offshore wind farm field technology, wind-powered electricity generation will become the important energy source source of Deposits in Eastern Coastal China area sustainable development.
The basis of wind-powered electricity generation unit is the important ring that marine wind electric field is built, and the blower foundation of using mainly contains following two kinds of forms at present:
One, steel pipe single pile basis
As the basis, top connects the blower fan king-post by single steel pipe on steel pipe single pile basis.The diameter of stake is decided according to the size of load, generally about 3～5m.The degree of depth of inserting sea bed is relevant with soil condition, can perhaps be holed on sea bed by hydraulic hammer or vibrating hammer injection sea bed.
The load on basis is bigger because blower fan is passed to, and the steel using amount on steel pipe single pile basis is bigger, and cost of materials is higher; Simultaneously, because single diameter of steel tube is thick, weight is big, needs specialized apparatus during construction, operating expenses is higher; In addition, to washing away sensitivity, need carry out the protection against erosion protection at sea bed and basic joint.
Two, many pile concretes basis
Many pile concretes basis is made up of the stake of many coagulation great soil groups or steel pipe pile and steel concrete cushion cap.The top king-post is connected with the steel embedded part of steel concrete cushion cap.The basis of this form generally is used for the blower foundation on land.
Many opposing upper loads are adopted on many pile concretes basis, in addition in the material concrete than great, though can save certain cost of materials than steel pipe single pile basis, but when being used for offshore wind turbine foundation, cause site operation very complicated: to be concreting, need peripheral on construction ground steel sheet pile or the whole heavy tube (cofferdam) beaten, form the operating space of sealing, constantly draw water simultaneously.Concrete is transported to on-the-spot difficulty, and on-the-spot pile sinking, concreting and maintenance complexity cause the working measure expense high, and construction period is longer simultaneously, and the engineering time of single blower foundation was at 4～5 months.Therefore, the overall economic efficiency of many pile concretes scheme is not good.
The utility model content
Task of the present utility model provides a kind of offshore wind turbine steel work basis, it has solved the existing problem in above-mentioned prior art steel pipe single pile basis and many pile concretes basis by the new steel structure basis that is applicable to offshore wind turbine foundation that stake of steel pipe class and conversion steel work are formed.
Technical solution of the present utility model is as follows:
A kind of offshore wind turbine steel work basis, it comprises the stake of steel pipe class, the quantity of described steel pipe class stake at the conversion steel work of the top of steel pipe class stake connection as cushion cap, is installed blower fan king-post on the top of conversion steel work more than two.
The stake of described steel pipe class is straight stake.
The stake of described steel pipe class is a taper pile.
Described conversion steel work is real abdomen formula conversion steel work.
Described conversion steel work is a lattice conversion steel work.
The stake of described steel pipe class is the round steel pile tube.
The stake of described steel pipe class is the square steel pile tube.
The stake of described steel pipe class is the polygon steel pile tube.
The stake of described steel pipe class is the steel tube concrete pile of interior concrete placing.
The stake of described steel pipe class is the concrete-filled steel tubular hollow stake.
Offshore wind turbine steel work of the present utility model basis is made up of stake of steel pipe class and conversion steel work, this novel offshore wind turbine foundation system is applicable to the blower fan unit of building shallow sea and intertidal zone in, especially blower fan unit in intertidal zone is used this base form, and its advantage is more outstanding.
Many steel pipe piles of the present utility model add conversion steel work foundational system to be compared with existing blower foundation form, has following advantage:
1, easy construction, quick.
The pile sinking speed of on-the-spot piling bar is very fast; The conversion steel work can be transported to on-the-spot the installation at produce in factory.Can adopt bolt to be connected between conversion steel work and the piling bar, the field Welding amount is little, and speed of application is exceedingly fast, short construction period, and the working measure expense is low.
2, comprehensive benefit is good.
Because adopt many schemes, the piling steel using amount is reduced significantly than steel pipe single pile basis; Shorten significantly on the more pile concrete of construction period basis; The working measure expense reduces significantly.Therefore, at aspects such as comprehensive steel using amount, construction cost and construction periods, overall economic efficiency is good.
3, wave load is little.
Compare with many pile concretes basis, the steel structure member cross section is little, and it is corresponding less therefore to bear wave load, favourable to structure.
4, opposing blower fan king-post moment of flexure ability is strong.
Compare with steel pipe single pile and many pile concretes basis, the planar dimension of conversion steel work is easy to do greatly, after the spacing between many piles widens, makes this kind base form have the ability of stronger opposing blower fan king-post moment of flexure.
