Abstract
The invention discloses a wind power tower foundation with an inverted frustum and an independent column combined. A concrete inverted frustum and a concrete independent column combined form is used, and the lateral thrust resistance and the foundation structure of earth and the dead weight of filled earth are used simultaneously to resist working loads produced by a wind power tower. And the contact surface of the concrete inverted frustum with the concrete independent column is increased, so that horizontal displacement and born ultimate loads of the foundation bottom are reduced. The wind power tower foundation with the inverted frustum and the independent column combined has the advantages of being high in load resistance, good in stability and low in project manufacture cost.
Description
[technical field]
The present invention relates to generation power foundation of wind power, especially the inversed taper platform generation power foundation of wind power of being combined with insulated column.
[background technology]
Land wind power generation stepped basis is beam and slab type basis and board-like independent spread footing mostly at present.Although its construction technology is ripe, also has a lot of problems: lack the passive earth pressure of consideration foundation soil side to the effect on basis, need larger base plate diameter resist overturning moment; Need section area or the thickness of slab of the larger beam of design to go to satisfy basic shear-stable requirement.
The insulated column basis also becomes the main optional type of generation power foundation of wind power.It greatly reduces reinforcing bar and concrete consumption, but also needs larger buried depth to satisfy the designing requirement of tower cylinder, namely wants more excavated volume, and this has just increased the cost of engineering.
The present invention namely proposes the generation power foundation of wind power that inversed taper platform is combined with insulated column for the problems referred to above research.
[summary of the invention]
The technical problem to be solved in the present invention provides the generation power foundation of wind power that inversed taper platform is combined with insulated column, adopt the concrete inversed taper platform to combine with the concrete insulated column, utilize simultaneously anti-thruster ability and the foundation structure of soil and buried the deadweight of banketing, resist the working load of wind power generation stepped generation, and by increasing the contact area of concrete inversed taper platform and the soil body, reach the effect that reduces foundation bottom horizontal movement and suffered ultimate load, it is strong to have the load resistance, good stability, the characteristics that construction costs is low.
For solving the problems of the technologies described above, the generation power foundation of wind power that inversed taper platform of the present invention is combined with insulated column, adopt following technical scheme:
The generation power foundation of wind power that inversed taper platform of the present invention is combined with insulated column, comprise concrete cushion, described concrete cushion is provided with the concrete insulated column, described concrete insulated column is provided with the concrete inversed taper platform, the inner vertical direction of described concrete insulated column is provided with prestressed anchor, and described prestressed anchor upper end directly is connected with wind power generation stepped.
Described concrete inversed taper platform is circular cone structure or frustum of a pyramid structure, and wherein frustum of a pyramid structure comprises hexagonal pyramid platform structure or eight frustum of a pyramid structures.The preferred circular cone structure of the present invention.
Described concrete insulated column inside also is provided with and prestressed anchor reinforced steel connected vertically.Be provided with cylindrical hole in the described concrete insulated column.
The generation power foundation of wind power that inversed taper platform of the present invention is combined with insulated column, the form that adopts the concrete inversed taper platform to combine with the concrete insulated column, utilize simultaneously anti-thruster ability and the foundation structure of soil and buried the deadweight of banketing, resist the working load of wind power generation stepped generation, and by increasing the contact area of concrete inversed taper platform and the soil body, reach the effect that reduces foundation bottom horizontal movement and suffered ultimate load, it is strong to have the load resistance, good stability, the characteristics that construction costs is low.

[specific embodiment]
Below in conjunction with accompanying drawing embodiments of the present invention are elaborated.
A kind of glass of type concrete of the present invention wind-force power generation column basis, comprise concrete cushion 1, concrete insulated column 2, concrete inversed taper platform 3, and the prestressed anchor 4 that is located at concrete insulated column 2 inner vertical directions, and the reinforced steel 5 vertical with prestressed anchor 4.Described concrete inversed taper platform 3 is circular cone structure or frustum of a pyramid structure, and wherein frustum of a pyramid structure comprises hexagonal pyramid platform and eight frustum of a pyramid structures.The preferred circular cone structure of the present invention.
When constructing at the scene, excavate first ground, in ground basal part compacting and build one deck concrete cushion 1, then build out concrete insulated column 2 at concrete cushion 1, backfill inversed taper platform bottom excavation soil, at concrete insulated column 2 top concreting inversed taper platforms 3, described concrete insulated column 2 and the 3 formed by integrally casting moulding of concrete inversed taper platform are provided with cylindrical hole 6 in the described concrete insulated column 2 again.
The consumption of described prestressed anchor 4, reinforced steel 5 arranges according to the actual requirement of engineering of this structure; Described prestressed anchor 4 is in the even annular array of the circumferencial direction of concrete insulated column 2, the quantity of prestressed anchor 4 with and the layout that arranges of annular mainly determined by wind power generation stepped load.In the work progress, described prestressed anchor 4 peripheral parcel pvc pipes or other are fit to the tubular material of replacement.Described reinforced steel 5 is built rear prestressed anchor 4 and is kept vertically to guarantee concrete material, and add the structural strength of reinforced concrete insulated column 2 with equidistant evenly distributed at the vertical direction of prestressed anchor 4.During connection, described prestressed anchor 4 upper ends directly are connected with wind power generation stepped.
