Description

A kind of fan platform installation foundation
Technical field
It the utility model is related to wind power engineering technical field, and in particular to a kind of fan platform installation foundation.
Background technology
At present, the land blower foundation commonly used both at home and abroad uses reinforced concrete spread foundation more, and common form includes:Circle The big plate basis of shape expanded type, circular rib mat foundation, polygon rib beam type basis, prestressed anchor basis, prestressed bolt base Plinth and prestressed bolt anchor rod foundation etc..These base forms still fall within traditional circular table or column type gravity-type basis, Base form is single, it is impossible to different topographic and geologic conditions is adapted to, and base concrete dosage is big, from great;Although in advance should Power anchor rod foundation, prestressed bolt basis and prestressed bolt anchor rod foundation, by applying prestressing force to crab-bolt or anchor pole, are realized Blower fan tower barrel is reliably connected with basic and ground, but blower fan still has together with basis one under the effect of larger moment load The risk toppled is acted, its basic concrete amount of the crab-bolt used at present is excessive, and its stability is bad, and the time is easy for a long time Cause to rupture;It is located in the wind power plant of mountain area or hilly country, blower fan is arranged on rock foundation mostly, is presently used for rock Blower foundation on stone ground mainly has two kinds of forms of ordinary reinforced concrete spread foundation and Rock Bolt Foundation.
(1) ordinary reinforced concrete spread foundation:During construction, the larger-size base in chassis is excavated first on rock foundation Hole, then by concreting in foundation ditch, forming spread foundation, spread foundation diameter is up to 15-30 rice, highly up to 3-5 rice, Need a large amount of armored concrete of about 300-500 cubic meters to pour to form.Spread foundation can only lean on the scale of construction and buried depth band on basis Tilting moment is resisted in the deadweight and backfill soil pressure come.Although such a basic engineering experience is ripe, easy for construction, excavate Amount is big, and backfill is more.When this kind of basis is used for fractured rock ground, still there is larger superiority.But such as run into engineering rock mass point Level for it is harder and above, complete and the above rock foundation when, not only quantities is big, greatly and can also be dug motionless because of excavated volume Cause duration problem and equipment attrition problem.In addition, conventional foundation side's amount is big, the engineering time of disposable continuous placing is completed It is long, but Changes in weather fast day and night temperature in mountain region is larger, wind power plant road conditions difference easily freeze, cause concrete mix, Easily gone wrong in conveying, casting process.The construction cost of ordinary reinforced concrete spread foundation, construction quality, duration, environmental protection etc. Drawback highlights.
(2) Rock Bolt Foundation.Rock Bolt Foundation undertakes the tension between basis and rock foundation by anchor pole, Key dimension and buried depth are effectively reduced, considerably reduces quantities.Existing Rock Bolt Foundation includes foundation ring, reinforcing bar Concrete plummer, the tension anchor pole for being secured to connection, the anchor pole are uniformly arranged in armored concrete plummer bottom periphery One end is located in rock foundation, and the other end is located in armored concrete plummer, holds rock foundation by anchor pole and is mixed with reinforcing bar Native plummer is coagulated, a series of problems for solving ordinary reinforced concrete spread foundation.But because anchor pole is direct embedment base In plinth concrete and rock foundation, only after anchor pole and basis start to produce disengagement and between basement rock and anchor pole it is closely knit sting it is next, It anchor pole is started tension and extend gradual Developed fiber strength generation pulling force.This segment length is difficult to determine and is difficult to control, and adds Fatigue Load, tower tilt problem may occur in actual motion.
Thus more or less all there are some, it is necessary to change in both the above basis.
Utility model content
The purpose of this utility model provides a kind of fan platform installation foundation, solves one in above-mentioned prior art problem It is or multiple.
According to a kind of fan platform installation foundation of the present utility model, including reinforced concrete foundation, located at the reinforcing bar Concrete foundation bed course below concrete foundation, the prestressed bolt located at the reinforced concrete foundation and located at the steel The concave part on reinforced concrete basis, the concave part are provided with connecting plate, and it is solid that some connections are installed with the connecting plate Fixed pole, the bar that is connected sequentially passes through the connecting plate, reinforced concrete foundation and concrete foundation bed course, described pre- Stress crab-bolt lower end is reserved with installing space, and the installing space is located in the reinforced concrete foundation inside.
A kind of fan platform installation foundation provided by the utility model, it is simple in construction, it is easy for installation, by being mixed in reinforcing bar Solidifying earth foundation surrounding installs reserved basis additional, and is fixedly installed in reinforced concrete foundation by drawstring, this blower fan can be put down Platform installation foundation is applied to many adverse circumstances, such as mountain area, hills area, and played further by the bar that is connected Stablizing effect, a kind of stability of fan platform installation foundation can be effectively increased, and reinforced concrete foundation need not occupy a lot Area it is ensured that the stability of blower fan, the dosage of concrete greatly reduce, saved material, cost is lower.
In some embodiments, the perisporium of reinforced concrete foundation four is equipped with suspension ring, and the suspension ring, which are provided with, to be drawn Rope, the drawstring other end are fixedly installed in reserved basis.
Brief description of the drawings
Fig. 1 is a kind of a kind of structural representation of fan platform installation foundation of embodiment of the present utility model.
Embodiment
With reference to Figure of description, the utility model is described in more detail.
As shown in fig. 1, a kind of fan platform installation foundation, including reinforced concrete foundation 1, it is installed on armored concrete The concrete foundation bed course 2 of the lower section of basis 1, it is installed on the prestressed bolt 3 of the reinforced concrete foundation 1 and is opened in steel The concave part 4 on reinforced concrete basis 1, the effect of concrete foundation bed course 2 cause total basis to beat jail, are easy to pour steel Reinforced concrete basis 1, the middle part top end face of reinforced concrete foundation 1 are provided with concave part 4, pass through the sides of pouring such as bolt at concave part 4 Formula is installed with connecting plate 5, and some bars 6 that are connected are installed with by flange or bolt on connecting plate 5, and connection is solid Fixed pole 6 sequentially passes through connecting plate 5, reinforced concrete foundation 1 and concrete foundation bed course 2, and deep insertion soil or rock downwards In layer, lithosphere, then need first to be punched with drilling machine in this way, is inserted into the bar 6 that is connected, and in gap casting concrete, Wherein, be connected bar 6 upper end be no more than reinforced concrete foundation 1 upper surface, it is pre- in the lower end of prestressed bolt 3 Installing space 7 is left, installing space 7 is located in the inside of reinforced concrete foundation 1, and the effect for being reserved with installing space 7 is Maintenance personal is facilitated to install or change the flange of the lower end of prestressed bolt 3.
