Abstract
The utility model discloses a jacket fan foundation connecting piece which comprises a jacket. A connecting piece steel pipe is sleeved outside a jacket top steel pipe, steel blocks are fixed on a jacket top steel pipe outer wall and/or a connecting piece steel pipe inner wall, and grouting materials are filled in a gap between the jacket top steel pipe and the connecting piece steel pipe. The lower end of the connecting piece steel pipe is provided with a sealing ring, and a fan tower is sleeved outside the connecting piece steel pipe. The jacket fan foundation connecting piece can guarantee precise leveling on top of the connecting piece steel pipe, meets hoisting requirements of an upper portion fan high-rise structure, and enables a jacket fan foundation to be popularized and applied to the offshore wind plant field.
Description
Technical field
The utility model relates to the jacket blower foundation, particularly a kind of jacket blower foundation connector.
Background technology
Obtained in oil platform, the offshore lighthouse construction at sea of jacket basis using widely.It is reported, China in the Bohai Sea, the offshore oil jacket set up of East Sea depth of water 15m～80m marine site all adopts the jacket basis.Wind energy turbine set basic engineering field at sea, large when single-machine capacity, when the depth of water is darker, compare the blower foundation of other pattern, jacket basis pattern has clear superiority at aspects such as structural shape, construction costs, construction speeds.
At present, the structural shape of the jacket blower foundation of general marine wind electric field is: lifting sinking jacket, stake is squeezed in the sea bed along the firm sleeve pipe on jacket basis, between the firm sleeve pipe on stake and jacket basis, pour into High Strength Non-shrinking Filling Material, carry out the leveling of jacket top.This structure is better in the usable condition in the non-basement rock of deep water marine site, puts in place but the jacket top is difficult to accurate leveling.According to the requirement of top blower fan tall and slender structure lifting, very high to the levelness requirement at jacket top, the leveling at jacket top is directly connected to the safety of top blower fan tall and slender structure, may cause toppling of top blower fan tall and slender structure.And jacket basis wind-engaging, wave, the impact of the continual drive marine such as trend, in the middle of the basis itself is in always and rocks, existing construction equipment and construction technology can only be carried out coarse balance to the jacket top, its precision does not reach the requirement of blower fan lifting fully, though make the jacket blower foundation have certain advantage in wind energy turbine set basic engineering field at sea, but the very difficult difficult problem of top blower fan tall and slender structure lifting that exists the jacket top to be difficult to accurate leveling and cause, therefore solve the problem of the accurate leveling in jacket top, can make the jacket blower foundation be promoted and use in the wind energy turbine set field at sea.
Summary of the invention
Technical problem to be solved in the utility model is, not enough for prior art, a kind of jacket blower foundation connector is provided, the accurate leveling at the existing jacket blower foundation top of solution is hard problem very, satisfy the lifting requirements of top blower fan tall and slender structure, make the jacket top accurately leveling put in place.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of jacket blower foundation connector, comprise jacket, jacket top steel pipe outer cover has the connector steel pipe, be fixed with bloom on jacket top outer wall of steel pipe and/or the connector steel pipe inner wall, be filled with grouting material in the space between jacket top steel pipe and the connector steel pipe, connector steel pipe lower end is provided with joint ring, and connector steel pipe overcoat has blower fan tower barrel.
As preferred version, described bloom scribbles the hemispherical bloom of strong viscosity polyester material for the surface.
As preferred version, described grouting material is High Strength Non-shrinking Filling Material.
As preferred version, the bloom on jacket top outer wall of steel pipe and the connector steel pipe inner wall is interspersed.
The hemispherical steel functional mainly contains 2 points: the one, and can be effectively that the force transmission of top blower fan tall and slender structure is basic to jacket; The 2nd, the hemispherical bloom has the intensity advantages of higher, can improve the structural strength of connector.
High Strength Non-shrinking Filling Material is a kind of liquid material, has the advantages such as high, the large fluidised form of intensity, microdilatancy, and can condense into rapidly the solid shape.By the effect of High Strength Non-shrinking Filling Material, connector steel pipe, hemispherical bloom, jacket top steel pipe are linked to be one, make connector and jacket blower foundation be linked to be integral body, guarantee that stressed property and the intensity of total is not affected.
Compared with prior art, the beneficial effects of the utility model are: because the joint ring of connector can be according to the inclined degree of jacket top steel pipe, mode by welding is adjusted accordingly, therefore can guarantee the accurate leveling of connector steel pipe top, reach the lifting requirements of top blower fan tall and slender structure, make the jacket blower foundation be promoted and use in the wind energy turbine set field at sea.

The specific embodiment
As shown in Figures 2 and 3, the utility model one embodiment comprises jacket, jacket top steel pipe 2 outer cover have connector steel pipe 1, be fixed with the hemispherical bloom 4 that the surface scribbles strong viscosity polyester material on jacket top steel pipe 2 outer walls and connector steel pipe 1 inwall, be filled with the rising sun KX of section series High Strength Non-shrinking Filling Material 3 in the space between jacket top steel pipe 2 and the connector steel pipe 1, connector steel pipe 1 lower end is provided with joint ring 5, and connector steel pipe overcoat has blower fan tower barrel.
Joint ring plays vital effect in whole connector, can the problem that be related to the accurate leveling in jacket blower foundation top solve smoothly, the welding of joint ring is adjusted according to the inclined degree of jacket top steel pipe, guarantee that joint ring is in the state of abswolute level, the lower end of connector steel pipe is welded on the joint ring.
The hemispherical bloom is owing to its shape and welding position, and function mainly contains 2 points: the one, and can be effectively that the force transmission of top blower fan tall and slender structure is basic to jacket; The 2nd, the hemispherical bloom has the intensity advantages of higher, can improve the structural strength of connector.The effect that the hemispherical bloom is interspersed is as follows: have be easy to fill grouting material, be more conducive to the top force transmission to substructure, improve the advantages such as ability that whole connector bears vertical shearing power.
High Strength Non-shrinking Filling Material is a kind of liquid material, has the advantages such as high, the large fluidised form of intensity, microdilatancy, and can condense into rapidly the solid shape.By the effect of High Strength Non-shrinking Filling Material, connector steel pipe, hemispherical bloom, jacket top steel pipe are linked to be one, make connector and jacket blower foundation be linked to be integral body, guarantee that stressed property and the intensity of total is not affected.
