Abstract
The invention discloses a seaborne wind-power suction type ring-shaped base which comprises an inner side wall, an outer side wall, a top cover and storehouse dividing plates, wherein the inner side wall and the outer side wall are barrel-shaped structures which are coaxially arranged; a top cover is arranged on the top of the inner side wall and the top of the outer side wall to cover a gap between the inner side wall and the outer side wall; and the storehouse dividing plates are arranged at equal distance between the inner side wall and the outer side wall for dividing a part between the inner side wall and the outer side wall into at least two equal-area branch storehouses. Construction cost of the seaborne wind-power suction type ring-shaped base is reduced, base materials are reduced in case of guaranteeing base bearing force; and moreover, through the split storehouse type structure, the base levelness is kept in a sinking process.
Description
Technical field
The invention belongs to offshore wind power foundation engineering field, especially a kind of offshore wind farm suction type ring-type basis.
Background technology
Wind energy on the sea, as a kind of reproducible clean energy resource, becomes the new direction alleviating global energy anxiety situation.But
It is that the important component part offshore wind power foundation as offshore wind generating has construction cost height, offshore construction and peace
The features such as dress difficulty is big.Blower fan belongs to high-rise structure, and bearing huge moment of flexure, to be that offshore wind power foundation is different from other common
The key character of architecture basics.The base form of offshore wind farm mainly has：Gravity type foundation, single-pile foundation, High-Rise Pile Cap Foundation,
The base forms such as suction type bucket foundation, tripod basis.Gravity type foundation installation cost is low, but need to carry out pre- place to sea bed
Reason；Need the mobile basis of jumbo.Single-pile foundation simple production process, installation experience enriches, and difficulty of construction is big, by sea bed and wind
Machine weight is big.High-Rise Pile Cap Foundation is made up of foundation pile and top cushion cap, can use, but structure is totally inclined in soft soil foundation
Thickness, deadweight is larger.The suction type cylinder of suction type bucket foundation steel and concrete structure or steel construction is it is adaptable to sand, cohesive soil or silt
Shale soil, easy for installation, low cost, but be not suitable for washing away sea bed, lithology sea bed and compressible muddy sea bed.Tripod
Basis is made up of three leg jackets, builds and easy construction, need not do any sea bed and prepare, but be unsuitable for sea bed and there is big face
The ground of long-pending rock.Steel frustum space frame is constituted again on jacket basis, and intensity is high, and installation noise is little, lightweight, but structure
Complicated；Involve great expense；The lower fatiguability of wave effect lost efficacy, and compared with traditional marine structure basis, not only will bear enough
Vertical load, still suffer from big moment of flexure and larger horizontal force action.What blower fan was affected by under conditions of work is not only
The effect of dead load, but the dynamic action of three-dimensional, so, offshore wind power foundation has the complexity of loading characteristic and does not know
Property, these can affect the type selecting of offshore wind power foundation.
Content of the invention
The invention provides a kind of offshore wind farm suction type ring-type basis, this foundation structure pattern simple it is easy at sea
Construction, reduces construction cost, warehouse separated type structure can make this basis keep base water Pingdu in sinking watching.
The present invention is achieved by the following technical solutions：
A kind of offshore wind farm suction type ring-type basis, including madial wall, lateral wall, top cover and point storehouse plate, madial wall is with outward
Side wall is the tubular structure being coaxially disposed, and top cover is arranged at the top of madial wall and lateral wall, cover madial wall and lateral wall it
Between space, being placed equidistant a point storehouse plate between madial wall and lateral wall will be divided at least two between madial wall and lateral wall
Point storehouse of homalographic, the height on offshore wind farm suction type ring-type basis is 6～15m, a diameter of 15～35m of madial wall, thickness
For 300～400mm, a diameter of 25～40m of lateral wall, thickness is 300～400mm.
And, a kind of described offshore wind farm suction type ring-type basis is steel construction or reinforced concrete structure.
And, described the highly preferred of offshore wind farm suction type ring-type basis is 8～10m.
And, the diameter of described madial wall is preferably 20～30m.
And, the diameter of described lateral wall is preferably 20～30m.
And, the thickness of described madial wall is preferably 330～370mm.
And, the thickness of described lateral wall is preferably 330～370mm.
And, the quantity in described point storehouse is preferably 6～12, and point storehouse plate thickness is 20～30mm.
Compared with prior art, the invention has the beneficial effects as follows：A kind of offshore wind farm suction type ring-type basis reduces suction
The construction cost of power formula wind power foundation, reduces basic materials in the case of ensureing foundation bearing capacity, in terms of vertical bearing capacity,
End resistance and collateral resistance are carried by madial wall, lateral wall and a point storehouse plate, and warehouse separated type structure can make this basis in sinking watching
Keep base water Pingdu.
