Description
Technical field
This utility model is related to a kind of marine wind electric field single-pile foundation.
Background technology
Domestic marine wind electric field through exploration for many years and related engineering practice, the offshore wind turbine foundation bag of successful Application
Include single-pile foundation, catheterostat basis（Various patterns）, High-Rise Pile Cap Foundation, the foundation pattern such as low pile cap basis.In general,
Comprehensive country's marine wind electric field physical condition and construction ability, single-pile foundation is a kind of common offshore wind power foundation pattern,
Europe is also widely applied, and this is due to the characteristics of which has low cost, easy construction and short construction period, being to throw at present
The foundation pattern of capital's highly desirable employing when marine wind electric field is built.
Current country's marine wind electric field sea region with to the north of is that the European offshore wind park condition of representative is compared with certain
Difference, European North Sea Regional Geological Conditions are that have a preferable bearing capacity sea bed as representative with sand, coarse sand, sand gravel, and I
State Jiangsu, Zhejiang, Hebei are with weak soil（Superficial layer is with mud, muck soil, bury）Based on stratum；Guangdong, Fujian, the Liao Dynasty
Peace Shandong with superficial layer weak soil, bottom be basement rock to represent stratum, and affected by typhoon, frost etc., tidal range change greatly, wave
It is higher, there is certain difference with European offshore wind park marine environmental conditions, and single-pile foundation be by side soil pressure come
Opposing Wind turbines load, it is using the frictional force opposing vertical load between stake and soil, higher to the requirement of sea bed geological conditions, because
And it is not suitable for the marine wind electric field of sea bed complex geologic conditions.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of marine wind electric field single-pile foundation, can be applied to various
The marine wind electric field of sea bed complex geologic conditions.
In order to solve above-mentioned technical problem, the technical scheme is that：A kind of marine wind electric field single-pile foundation, including list
Pile pipe, single pile pipe are vertically supported in closely knit layer surface through bottom silt layer, have been inserted into internal model steel cylinder in single pile pipe, in single pile
Gap between pipe and internal model steel cylinder has been inserted into many steel-pipe piles, steel-pipe pile lower end insertion seabed dense layer or strongly weathered sand-rock
It is interior, wire basket and maritime concrete are provided with and internal model steel cylinder between on the inside of single pile pipe.
Each steel-pipe pile is uniformly distributed around internal model steel cylinder axis.
An annular end cap moving up and down is cased with outside single pile pipe, the end cap is made up of polylith limb, each lobe
Pass through screw detachable connection between piece.
The beneficial effects of the utility model are：The present invention combines the principle of many pile tubes, by single pile and hard base basis or batholith
Basis is connected, and had both remained the characteristic that stake is wiped in the stake that singly rubs, and the characteristics of have a clump of piles again, had saved the investment of marine wind electric field, while contracting
The short construction period of marine wind electric field, it is possible to use implement by having equipped with construction technology, it is adaptable to all kinds of sea beds ground
The marine wind electric field of matter complicated condition, and construction method is simple, it is not necessary to Special Equipment is used, operating expenses is low.
Description of the drawings
The present invention is described further below in conjunction with the accompanying drawings：
Fig. 1 is the cross-sectional view of the following embodiments of this utility model 1,
Fig. 2 is the generalized section at A-A in Fig. 1,
Fig. 3 is the cross-sectional view of the following embodiments of this utility model 2,
Fig. 4 is the generalized section at B-B in Fig. 3.

Specific embodiment
Embodiment 1：
As illustrated in fig. 1 and 2：A kind of marine wind electric field single-pile foundation, including single pile pipe 1,1 top surface of single pile pipe and blower fan tower barrel
Connection, single pile pipe 1 are vertically supported in closely knit layer surface through bottom silt layer, have been inserted into internal model steel cylinder 2 in single pile pipe 1,
Gap between single pile pipe 1 and inner membrance steel cylinder has been inserted into many steel-pipe piles 3,3 lower end of steel-pipe pile insertion seabed dense layer or strong
In weathered rock formation, wire basket and maritime concrete are provided with and internal model steel cylinder 2 between on the inside of single pile pipe 1, reaching will be single in bottom
The purpose that pile pipe is fixedly connected with steel-pipe pile.
Each steel-pipe pile 3 is uniformly distributed around 2 axis of internal model steel cylinder.
A kind of construction method of marine wind electric field single-pile foundation, comprises the steps：
The first step, piling construction is carried out first by pile hammer, single pile pipe 1 is driven piles to dense layer table through mud
Face, now single pile pipe 1 cannot continue piling by dense layer, both cannot be by the use of dense layer as supporting course；
Second step, using the basic erection construction platform of single pile pipe 1, using multiple steel-pipe piles 3 drive piles on the inside of single pile pipe 1 to
Projected depth, such as weak weathered stratum, can adopt 3 embedding rock construction technology of steel-pipe pile, and both steel-pipe pile 3 was driven piles after projected depth,
To 3 concrete perfusion of steel-pipe pile；
3rd step, 1 bottom sea bed debris of cleaning single pile pipe, then core insert steel cylinder 2, on the inside of single pile pipe 1 and internal model steel
Between cylinder 2 after lower wire basket, maritime concrete 4 is poured, single pile pipe 1 is fixedly connected with steel-pipe pile 3.
The present invention combines the principle of many pile tubes, the characteristics of being driven piles by fragmentation strong-weathered rock using steel-pipe pile 3, by single pile
1 is connected with hard base basis or batholith basis, had both been remained the characteristic that stake is wiped in the stake that singly rubs, and the characteristics of have a clump of piles again, had been saved sea turn
The investment of electric field, while shortening the construction period of marine wind electric field, it is possible to use implement by having equipped with construction technology,
Suitable for the marine wind electric field of all kinds of sea bed complex geologic conditions, and construction method is simple, it is not necessary to uses Special Equipment, applies
Expenses of labour is low.
Embodiment 2：
The present embodiment is the further improvement made on the basis of embodiment 1, specially：As shown in Figures 3 and 4, in list
An annular end cap 6 moving up and down is cased with outside pile pipe 1, the end cap 6 is made up of polylith limb 61, between each limb 61
By screw detachable connection.Drive piles to closely knit layer surface in single pile pipe 1, end cap 6 can be enclosed within outside single pile pipe 1, be allowed
End cap 6 sinks to seabed along 1 outer wall of single pile pipe, the piling of end cap 6 is pressed in mud or closely knit layer surface, is that single pile pipe 1 is provided
Support, prevent single pile pipe 1 from inclining.When mounted, can fetching each piece of limb 61, to be looped around single pile pipe 1 peripheral, will by screw
Each limb 61 connects integral.
