It is fixed, it ensure that the normal use and service life of wind turbine.
The technical scheme is that：
A kind of installation method of blower foundation ring, has specifically included following steps：
（1）, it is first that basic ring support embedded part and lower rebar mesh sheet is secured according to air door direction location and installation, check true
Recognize errorless after-pouring concrete cushion；After the completion of pouring, the center of blower foundation center line and foundation ring support element is measured,
The absolute altitude of three pre-embedded steel slabs in bed course is measured using automatic compensated level again, calculates the height of three pre-embedded steel slabs in bed course
Difference adjusts three support adjusting rods according to the height difference of three built-in fittings, foundation ring apical side height, pacifies the support adjusting rod of each point
Upper plane after dress is on same absolute altitude, blower foundation tower door mark direction and in 90 ° to 135 ° angles of prevailing wind direction；
（2）, foundation ring is sling into certain altitude degree with crane after, slowly rotate foundation ring, make 0 point of foundation ring label towards wind
Then machine basis tower door direction connects three support adjusting rods and three foundation bolts, is directed at corresponding exact position just
Position, while fastening support adjusting rod and foundation ring connecting screw and reach defined moment values；1 self leveling is equipped with during installation
Spirit level carries out tracking observation measurement, detects the height of equally distributed 12 points of foundation ring upper flange, the highest point and the lowest point
The difference of level value is no more than 1mm, if it exceeds the angle that should be then turned by accurately calculating three support adjusting rods, passes through jack
Coordinate three support adjusting rods, and readjust spirit level, detect again, measurement is so repeated with adjusting, until making
The levelness of foundation ring is controlled within the scope of defined；
（3）, after bed course reaches intensity value, by drawing snap the line on bed course, mark reinforcement location line, reinforcing bar sole plate connects
Head mutually staggers, and has been bound in the upper and lower mesh sheet reinforcing bar of sole plate, has set up steel pipe frame, for brace foundation master in work progress
Beam steel, while bind basic beam steel；
（4）, foundation forms using sizing punching block assembling, with the punching block slab supporting processed in advance, template after the completion of reinforcing bar
Seam will paste sponge strip mortar leakage prevention, and circular arc is made hoop and reinforced using reinforcing bar or steel pipe, is vertically reinforced with steel pipe and flitch, under
Portion's fulcrum spacing is not more than 60cm, and top fulcrum spacing is not more than 90cm spacing；
（5）, reinforcing bar be laid with and complete and after the completion of template support, casting concrete has been poured using periphery before concrete placings
Concrete is to the effect solid base ring of reinforcing bar, because base thickness is larger, vibration compacting during to ensure that lower floor pours is pouring lower floor
During concrete, the personnel of pouring, which should enter in steel reinforcement cage, vibrates.
Reinforcing bar, electric instrument built-in pipe are checked before the foundation forms molding, ensures reinforcing bar, electric instrument built-in pipe exhaustive, position
Put it is accurate, firmly install.
The sizing punching block surface smear interleaving agent, and the distortionless deformation of appearance, sticking two-faced adhesive tape band at form joint
With mortar leakage prevention.
Advantages of the present invention：
The installation steps of foundation ring of the present invention include basic embedded part installation, blinding layer pours, basic ring support is installed,
Foundation ring installation, foundation forms peace, reinforcement foundation binding and base concrete pour, and the design and installation of each installation steps are equal
It ensure that the intensity of foundation ring and the stability of mounting structure.
