Abstract
The utility model discloses a cup-shaped concrete foundation of a wind power generation tower, which comprises a concrete cushion layer, wherein a cup-shaped concrete pier with a wide upper part and a narrow lower part is arranged on the concrete cushion layer; prestressed anchor rods are arranged in the cup-shaped concrete pier in a vertical direction; and the upper ends of the prestressed anchor rods are directly connected with the wind power generation tower. With the adoption of the cup-shaped concrete pier structure, side push resistance of soil, a foundation structure and deadweight of buried filling soil are utilized; a contact area between the top end of the cup-shaped concrete pier and a soil body is increased; and the cup-shaped concrete foundation has the characteristics of high load resistance, good stability and low construction cost.
Description
[technical field]
The utility model relates to generation power foundation of wind power, and especially a kind of glass of type concrete wind-force power generation column is basic.
[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 considering the 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 utility model namely proposes a kind of glass of type concrete wind-force power generation column for the problems referred to above research basic.
[utility model content]
It is basic that the technical problems to be solved in the utility model is to provide a kind of glass of type concrete wind-force power generation column, adopt cup type concrete pier structure, utilize anti-thruster ability and the foundation structure of soil and bury the deadweight of banketing, resist the working load of wind power generation stepped generation, and by increasing the contact area of cup type concrete pier top and the soil body, reach the effect that reduces foundation bottom horizontal movement and suffered ultimate load, have opposing load strong, connective stability is good, the characteristics that construction costs is low.
For solving the problems of the technologies described above, a kind of glass of type concrete wind-force power generation column of the utility model is basic, adopts following technical scheme:
A kind of glass of type concrete wind-force power generation column of the utility model is basic, comprise concrete cushion, described concrete cushion is provided with cup type concrete pier wide at the top and narrow at the bottom, and the inner vertical direction of described cup type concrete pier is provided with prestressed anchor, and described prestressed anchor directly is connected with wind power generation stepped.Adopt cup type concrete pier structure, the top increases the contact area with the soil body, can reduce the excavated volume to the ground degree of depth when construction, reduces construction costs; While cup type concrete pier structure, its opposing load is strong, and connective stability is good.
The inside of described cup type concrete pier also is provided with the reinforced steel vertical with prestressed anchor.
Also be provided with arrangement of reinforcement in described cup type concrete pier.The consumption of described prestressed anchor, reinforced steel and arrangement of reinforcement arranges according to the needs of site operation, to strengthen the structural strength of cup type concrete pier.
Be provided with cylindrical hole in the middle of described cup type concrete pier, satisfying requirement of strength simultaneously, can reduce construction costs, save material.
A kind of glass of type concrete wind-force power generation column of the utility model is basic, adopt cup type concrete pier structure, utilize anti-thruster ability and the foundation structure of soil and bury the deadweight of banketing, and by increasing the contact area of cup type concrete pier top and the soil body, has opposing load strong, good stability, the characteristics that construction costs is low.
[description of drawings]
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is sectional view of the present utility model.
[specific embodiment]
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
A kind of glass of type concrete wind-force power generation column of the utility model is basic, comprise concrete cushion 1, cup type concrete pier 2, and the prestressed anchor 3 that is located at glass type concrete pier 2 inside, the reinforced steel 4 vertical with prestressed anchor 3 also is provided with arrangement of reinforcement 6 in described cup type concrete pier 2, be provided with cylindrical hole 5 in the middle of described cup type concrete pier 2, this structure design can reduce construction costs satisfying requirement of strength simultaneously, saves material.
When constructing at the scene, first excavate ground, tamp and build one deck concrete cushion 1 at the ground basal part, then build out a glass type concrete pier 2 on concrete cushion 1.
Described prestressed anchor 3, the consumption of reinforced steel 4 and arrangement of reinforcement 6 arranges according to the actual requirement of engineering of this structure; Described prestressed anchor 3 is in the even annular array of circumferencial direction of cup type concrete pier 2, the quantity of prestressed anchor 3 with and the layout that arranges of annular mainly determined by wind power generation stepped load.In work progress, the peripheral parcel pvc pipe of described prestressed anchor 3 or other suitable tubular material that replaces, and the tubular material that guarantees parcel prestressed anchor 3 can not surpass the scope of cup type concrete pier 2 at vertical direction. described reinforced steel 4 is with equidistant evenly distributed at the vertical direction of prestressed anchor 3, guaranteeing that concrete material builds rear prestressed anchor 3 and keep vertically, and strengthen the structural strength of cup type concrete pier 2.
During connection, described prestressed anchor 3 upper ends directly are connected with wind power generation stepped.
