Abstract
The utility model provides a marine wind power anti -floating pile with spiral pterygoid lamina, includes pile body and pterygoid lamina, and the pile body is the cavity stake, is equipped with the pterygoid lamina on the pile body inner wall, and the pterygoid lamina is spiral structure. Be equipped with the multiunit injected hole on the pile body lateral wall, the edge of a wing structure that is equipped with with the perpendicular setting of pile body is served at pile head no. 1 to the pile body, and edge of a wing structure is prismatic or pyramid, and edge of a wing structure is two at least. Through adopting above -mentioned structure, promoted the interior side resistance of pile foundation, it when filling the construction, has increased the combination degree between concrete and the pile body to carry out the later stage simultaneously, has improved the tensile ability of concrete, carrying out slip casting when construction, partial concrete makes and is connected through the concrete between pile body and the soil body in the soil body around the injected hole gets into the pile body outer wall, has greatly improved the withdrawal resistance of pile foundation, increased the frictional force and the anti - pulling capacity of pile body and secret soil layer, while and soil layer on every side produce synergism, can effectively improve the physics mechanical properties of low soil layer to increase substantially the bearing capacity and the frictional resistance of pile body.
Description
Technical field
This utility model relates to building field, particularly a kind of offshore wind farm uplift pile with spiral wing plate.
Background technology
In current offshore wind farm pile foundation, generally all use cylindrical stake.When typhoon, resist typhoon by stake deadweight and collateral resistance.When it has the drawback that when typhoon more than stake deadweight and collateral resistance, stake has the risk being pulled out, it is therefore necessary to improve present pile foundation, promotes offshore wind farm pile foundation resistance to plucking safety.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of offshore wind farm uplift pile with spiral wing plate, is applied in offshore wind farm pile foundation, it is possible to reach good effect, promotes offshore wind farm pile foundation resistance to plucking safety.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of offshore wind farm uplift pile with spiral wing plate, and including pile body and wing plate, pile body is hollow stake, and pile body inwall is provided with wing plate, and wing plate is sped structure.
In preferred scheme, described pile body sidewall is provided with organizes injected hole more.
In preferred scheme, described pile body is provided with flange structural vertically disposed with pile body on pile crown one end.
In preferred scheme, described flange structural is prismatic.
In preferred scheme, described flange structural is pyramid.
In preferred scheme, described flange structural at least two.
This novel provided a kind of offshore wind farm uplift pile with spiral wing plate, by adopting said structure, has the advantages that
(1) when adopting the pile-type of both ends open to construct, utilize the spiral wing plate structure that uplift pile inwall is provided with, promote the contact area of pile foundation and the soil body, thus promoting the interior collateral resistance of pile foundation, and when adopting the enclosed pile-type of pile crown to construct, spiral wing plate structure then can increase the conjugation between concrete and pile body in later stage pouring construction, to improve concrete resistance to tension；
(2) arranging on uplift pile sidewall and organize injected hole more, when carrying out mortar depositing construction, part concrete enters in the soil body around pile body outer wall through injected hole, makes to be connected by concrete between pile body with the soil body, drastically increases the withdrawal resistance of pile foundation；
(3) flange structural set by pile body pile crown end, add frictional force and the breakout capacity of pile body and sub-surface, produce synergism with the soil layer of surrounding simultaneously, the physico-mechanical properties of low soil layer can be effectively improved, and increase substantially bearing capacity and the frictional resistance of pile body.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of wing plate of the present utility model.
In figure: pile body 1, wing plate 2, injected hole 3, flange structural 4.
Detailed description of the invention
In figure, a kind of offshore wind farm uplift pile with spiral wing plate, including pile body 1 and wing plate 2, it is characterized in that: pile body 1 is hollow stake, and pile body 1 inwall is provided with wing plate 2, and wing plate 2 is sped structure.
In preferred scheme, described pile body 1 sidewall is provided with many group injected holes 3.Set injected hole, makes in carrying out mortar depositing construction step process, and concrete slurry can be entered in the soil body outside pile body by injected hole, the soil body and pile body is fixed, and promotes the overall pulling test power of pile foundation.
In preferred scheme, described pile body 1 is provided with flange structural 4 vertically disposed with pile body 1 on pile crown one end.Set flange structural 4, adds frictional force and the breakout capacity of pile body and sub-surface
In preferred scheme, described flange structural 4 is prismatic.
In preferred scheme, described flange structural 4 is pyramid.
In preferred scheme, described flange structural 4 at least two.
By adopting said structure, it is possible to effectively promote the extraction-resistant behavior of offshore wind farm pile foundation, it is ensured that stablizing of pile foundation, it is to avoid because of typhoon more than stake deadweight and collateral resistance, cause that the situation that pile foundation is pulled out occurs.
