Abstract
The invention provides a fan base built in a rock foundation. The fan base comprises a base pit on the rock foundation, wherein the sectional area of the base pit decreases from top to bottom; reinforced concrete is poured into the base pit to form a reinforced concrete body. The fan base further comprises a fan base ring, wherein the axis of the fan base ring is positioned in the vertical direction, and the lower portion of the fan base ring is built in the reinforced concrete body. The fan base built in the rock foundation is safe and reliable in structure, capable of reducing floor area, small in reinforced concrete consumption, and capable of greatly reducing construction cost. Furthermore, due to the fact that the structural shape of the reinforced concrete body in the fan base only needs to be changed, and other procedures are not needed, the construction process is simple.
Description
Technical field
The present invention relates to the blower foundation of a kind of build-in in rock foundation.
Background technology
Blower fan is that China is called for short the custom of gas compression and gas conveying machinery, and usually said blower fan comprises ventilation fan, blast fan, wind-driven generator.The blower foundation the present invention relates to refers in particular to wind driven generator base.
Wind-driven generator need to adopt blower foundation to be fixed on large ground, and the blower foundation that is arranged at present rock foundation mostly adopts expanded type reinforced concrete foundation.Stable in order to ensure blower foundation, avoid basis to come to nothing, sole plate size is larger.The blower fan of general single-machine capacity 2MW, hub height 80m, sole plate diameter reaches about 20m, the about 500m of concrete needing
3.Along with wind-powered electricity generation single-machine capacity constantly increases, the size on expanded type basis will continue to increase.Will bring following problem thus:
(1) the permanent floor space of blower foundation is large, increases and builds expropriation of land difficulty;
(2) difficulty of construction is large, and the disposable continuous pouring engineering time is long, generally over 14 hours;
(3) construction quality is difficult to control, and during winter construction of mass concrete, the heat of hydration, cushion cap be outside, and to produce the phenomenons such as temperature difference crack be all in work progress, to be difficult to the difficult problem avoiding and be difficult to deal carefully with;
(4) the concrete work consumption of blower foundation is large, increase of investment.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide the blower foundation of a kind of build-in in rock foundation, for solving the problem that prior art blower foundation floor space is large, concrete work consumption is large, difficulty of construction is large and construction quality is restive.
For achieving the above object and other relevant objects, the invention provides the blower foundation of a kind of build-in in rock foundation, comprise a foundation ditch on rock foundation, the cross-sectional area of foundation ditch progressively reduces from top to bottom; In foundation ditch, build steel concrete and form reinforced concrete body; It also comprises blower foundation ring, and the axis of blower foundation ring is positioned at vertical direction, and the bottom of blower foundation ring is embedded in reinforced concrete body.
Excavate the foundation ditch that cross-sectional area progressively reduces from top to bottom, then build steel concrete, make reinforced concrete body and rock foundation build-in form integral body, jointly stressed, structural safety is reliable; Due to foundation ditch from top to bottom cross-sectional area progressively reduce, reduced concrete amount and floor space.
Preferably, blower foundation ring by they sup-port the bottom at foundation ditch.
Preferably, the bottom of foundation ditch is provided with one deck plain concrete cushion layer.
Preferably, reinforced concrete body comprise with rock foundation build under all-in-one-piece, water building body and with under water building body and build fixed body on all-in-one-piece, under water the upper surface elevation of building body lower than the surperficial elevation of rock foundation, the soffit area of upper fixed body is less than down the upper surface area of watering building body, and the upper surface elevation of upper fixed body is higher than the surperficial elevation of rock foundation.Further preferred, under water the backfill formation backfill soil body in the space that the inner surface of the upper surface of building body, the side of upper fixed body and foundation ditch forms, the upper surface of the backfill soil body and the surface of rock foundation are positioned in same level.The backfill soil body covers on reinforced concrete body, played as the effect of whole blower foundation ballast, and to the protection of blower foundation be convenient to green manure.
Preferably, the inner surface of foundation ditch is that upper periphery diameter is greater than the round table-like of lower periphery diameter.Further preferred, the excavation slope of foundation ditch is slope.The foundation ditch of this shape is convenient to operation in excavation of foundation pit and foundation ditch.
As mentioned above, the blower foundation of build-in of the present invention in rock foundation, has following beneficial effect:
The blower foundation of this build-in in rock foundation, structural safety is reliable, saves land area, and concrete amount is little, has had significantly and reduce in construction costs; And construction technology is simple, only need to change the planform of the reinforced concrete body in blower foundation, do not need to increase other operation.
