Description
Technical field
The present invention relates to one kind construction basis, more particularly to a kind of foundation structure of wind-driven generator.
Background technology
Wind-driven generator is the device for converting wind energy into electric energy, and what is utilized due to it is natural wind energy, therefore with state
Energetically promotion of the family to energy-conserving and environment-protective, is increasingly valued by people and utilizes.
At present, the foundation main for installing wind power generating set on the ground will have following three types：
1st, solid gravity basis, this basis keeps stabilization completely by conducting oneself with dignity or loading native stone on this basis,
Concrete amount is more, and foundation excavation and native stone backfill amount are big, and this basis has stronger anti-pressure ability, but antidumping moment of flexure energy
Power is relatively low.
2nd, branch post fixing type basis, this basis is the method using excavating or drill, and imbeds ground by the pile tube of major diameter
Under, its antidumping moment of flexure ability depends primarily on the depth of pile tube injection underground.Reinforcing bar must be allocated in pile tube, and is poured at the scene
Build concrete.Although this basis construction cost is higher, difficulty of construction is larger, and plinth has stronger anti-pressure ability and antidumping
Moment of flexure ability.
3rd, grillage beam type basis, the cantilever beam stake on this basis is stretched out outward by concrete foundation, forms groined type, this
Plant structural excavation and backfill stone amount is less, but still need to pour a large amount of concrete at the scene, its antidumping moment of flexure ability receives base
The restriction of plinth area.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of simple structure, easy construction, short construction period, resistance to compression energy
Power and the strong foundation structure of wind-driven generator of antidumping moment of flexure ability.
To solve the above problems, the present invention is adopted the following technical scheme that：
A kind of foundation structure of wind-driven generator involved in the present invention, including：
One foundation ditch, the foundation ditch excavates to be formed on the ground, and it is concentric and circumference uniform distribution that foundation ditch bottom surface is provided with least three circles
Pile tube jack, for installing pile tube；
Many support pile tubes, are inserted respectively into two circle pile tube jacks of inner side and are fixed by filling concrete,
Its upper end is above ground level, for the installation support of the wind-driven generator that is connected；
Many reinforcing pile tubes, are inserted respectively into the pile tube jack on the outside of support pile tube and solid by filling concrete
Fixed, its upper end is higher than foundation ditch bottom surface, for the stake of reinforcing machine seat pipe；
Steel reinforcement cage, fixation is cast in foundation ditch, and the support pile tube and reinforcing pile tube are passed by steel reinforcement cage and mutually welded
Connect, for connecting support pile tube and reinforcing pile tube；
The installation support lower end is affixed with the upper end of the support pile tube, installs the fixation of support bottom and is cast on foundation ditch
In the concrete boss of side.
Used as further preferred, the foundation depth is 1~2M.
Used as further preferred, the installation support is by upper head plate, bottom plate and is connected between upper and lower end plate along circle
The connection tubing string of Zhou Junbu is constituted.
Used as further preferred, the support pile tube upper end is through the bottom plate for installing support and passes through adpting flange respectively
Welded with support is installed.
Used as further preferred, the steel reinforcement cage is that it is highly smaller by the hollow cylinder rack of reinforcement welding
In the depth of foundation ditch.
Used as further preferred, the height of the concrete boss is 500-800mm, and the support pile tube upper end is through peace
100~the 200mm of bottom plate of installation seat.
Used as further preferred, depth of the pile tube jack bottom apart from foundation ditch bottom surface is 6-8M.
As further preferred, the support pile tube and the height and weight of the quantity according to wind-driven generator of pile tube are reinforced
It is determined that and being proportional relation.
The beneficial effects of the invention are as follows：Simple structure, easy construction, short construction period, anti-pressure ability and antidumping moment of flexure
Ability is strong；Because support pile tube bottom is inserted and secured in pile tube jack, support pile tube upper end is affixed with installation support, and pours
Build in concrete boss, therefore support will can be installed and be firmly fixed on ground；Pass through reinforcing bar due to reinforcing pile tube upper end
Cage is affixed with support pile tube, therefore, it is possible to the firmness of reinforcing machine seat pipe stake, improves the anti-pressure ability and antidumping moment of flexure on basis
Ability.
