Abstract
The utility model relates to a partly inlay solid type raft board-like aerogenerator basis, this aerogenerator basis of its characterized in that is reinforced concrete cast in situ structure, and this structure includes soleplate, center pillar, a plurality of girder, and center pillar is at soleplate's center, and a plurality of girders are the edge of radial connection center pillar to soleplate, and there is the section of inlaying that stretches out soleplate bottom center pillar bottom. The utility model discloses at the during operation, the backfill jointly resists sliding, the power of toppling and each item internal force that upper portion eccentric load and structure dead weight arouse in embedded section, center pillar, foundation slab, foundation beam and the basis, reaches the purpose that reduces basic concrete engineering volume.
Description
Technical field
The utility model relates to wind energy development technical field, specifically a kind of part build-in type raft plate type wind generator foundation.
Background technology
Wind-driven generator is the TRT utilizing wind energy to promote blade rotation acquisition electric energy.Current wind-driven generator single-machine capacity increases gradually, and the engineering quantity of Conventional spread formula base concrete is larger.By adjusting basic build, making full use of the wedge action of top backfill weight and Foundation Rock Mass, the concrete work amount of blower foundation can be reduced.
Summary of the invention
The purpose of this utility model is to provide a kind of part build-in type raft plate type wind generator foundation, by by basic build-in in ground, utilize the build-in of rock mass to improve the stability of blower foundation.
The technical solution of the utility model is: a kind of part build-in type raft plate type wind generator foundation is reinforced concrete cast-in-situ structure, this structure comprises sole plate, center important actor, multiple girder, center important actor is at the center of sole plate, multiple girder radially connects the edge of center important actor to sole plate, and there is the fixed section stretching out sole plate zone center column bottom.
Linking beam is provided with between described multiple girders.
Girder, as main stress structure, is combined and is born top eccentric bending moment, horizontal thrust and dead load.
By the bottom build-in of wind driven generator base of the present utility model in basement rock, can improve the stability of blower foundation under various operation condition, embedding solid bottom can be in the important actor of base center the discharge ring or prestressed bolt composite member that are embedded with and are connected with top blower fan tower barrel; Sole plate is round reinforced concrete cast-in-situ structure, to keep the overturning or slip resistance analysis on whole basis, more than sole plate jointly resist the slippage that top fan loads and backfill heavily cause, power of toppling and every internal force to the girder of surrounding radiation and center important actor, sole plate, reach the object reducing base concrete engineering quantity.
Accompanying drawing explanation
Fig. 1 is the three-dimensional cutting structural representation of wind driven generator base of the present utility model.
Fig. 2 is wind driven generator base floor map of the present utility model.
Fig. 3 is the 1-1 sectional drawing in Fig. 2.
In figure, 1-fixed section, 2-center important actor, 3-sole plate, 4-girder, 5-linking beam.
Detailed description of the invention
As Figure 1-3, part build-in type raft plate type wind generator foundation of the present utility model is reinforced concrete cast-in-situ structure, this structure comprises sole plate 1, center important actor 2, multiple girder 4, center important actor is at the center of sole plate, multiple girder radially connects the edge of center important actor to sole plate, and there is the fixed section 1 stretching out sole plate zone center column bottom.Linking beam 5 is provided with between described multiple girders.It is a taper mesa-shaped that described center important actor stretches out sole plate part.Sole plate is round or polygon.Center important actor is round or polygonal, and the burying underground of built-in fitting that the size of important actor is connected with blower fan tower barrel according to inside requires to determine.
Sole plate following fixed section sidewall surrounding is combined completely with Foundation Rock Mass, and fixed section excavation build can be any build, and side excavation slope can be vertical cut or slope excavation, and the bottom of fixed section and basement rock are Full connected or part contact.
Install the discharge ring or prestressed anchor spigot that are connected with upper column cylinder in basis in advance, not shuttering during the fixed section concreting of bottom, carries out overall continuous placing afterwards.Bottom fixed section, center important actor, foundation bottom, girder form force structure jointly, opposing external loads.
