Electric field fan basic reinforcing engineering.
Background technology
In recent years, with the Large scale construction of domestic wind power plant, land wind turbine（Wind power generating set）Basis has gradually appeared one
Relatively low a little problems, wherein concrete strength are one of most common problems.As time goes by, the wind-powered electricity generation of this problem is exposed
Apparent ascendant trend is presented in number, and problem is more and more prominent.Blower foundation will be in dangerous work after there is intensity defect
Make state, Wind turbines is made to be not normally functioning, influences wind power plant power benefit.The wind that existing defects are reinforced
Machine basis, the reinforcement means generally used at present are that high-strength grouting is reinforced, but it can only play blind and restore concrete original
There is intensity.When blower foundation itself concrete strength cannot meet design requirement, this method can not improve wind turbine
Base concrete bearing capacity.
Invention content
The object of the present invention is to provide a kind of reinforcement means of blower foundation, with solve presently, there are blower foundation coagulation
The problem of native low strength is to cause blower foundation bearing capacity of concrete-filled to be unsatisfactory for requiring.Concrete scheme is as follows.
A kind of reinforcement means of blower foundation, for reinforcing original blower foundation, original blower foundation includes round platform
Part and the column part right over the round platform part, the reinforcement means mainly include the following steps that：
1）On the inclined-plane of the round platform part and bore vertical bar planting hole on the upper surface of column part；
2）Vertical reinforcement is set in the vertical bar planting hole, radial reinforcing bar, at least partly institute are bound on the vertical reinforcement
Radial reinforcing bar is stated above the inclined-plane of the round platform part and above the upper surface of column part；
3）Template is set up outside the steel bar framework that the vertical reinforcement and the radial reinforcing bar are formed；
4）The casting concrete into the template is formed simultaneously newly-increased armored concrete girt strip and newly-increased armored concrete ring
Shape important actor, the armored concrete girt strip are located on the inclined-plane of the round platform part and along the radial direction of round platform part
Extend, the reinforced concrete circular important actor is located at the top of the column part and around bottom section tower.
The reinforcement means of the present invention makes newly-increased armored concrete girt strip by radial reinforcing bar and vertical reinforcement and increases newly
Reinforced concrete circular important actor and original blower foundation form an entirety, newly-increased reinforced concrete circular important actor improves
The anchorage depth of original blower foundation ring, newly-increased armored concrete girt strip enhance the sidewise restraint of original blower foundation
Power.It should be noted that radial direction here is not exactly perpendicularly to the radial direction of horizontal direction, but projection in the horizontal direction
It is radial as radial.
Further, the step 1）In further include step：Correspond to the round platform on the side of the column part
The partial vertical bar planting hole drill radial direction bar planting hole；The step 2）In further include step：At least partly described radial reinforcing bar
End be inserted into the radial bar planting hole.Newly-increased reinforcing bar can be significantly enhanced in the radial reinforcing bar being inserted into radial bar planting hole
The lateral stability of concrete girt strip improves the service life of newly-increased armored concrete girt strip.
Further, the quantity of the newly-increased armored concrete girt strip is more than or equal to 4, and is evenly distributed in the circle
Above the inclined-plane of platform part；Preferably, the quantity of the newly-increased armored concrete girt strip is 8, can preferably be enhanced in this way
While the lateral restriction of original blower foundation, the cost of construction is reduced.
Further, the newly-increased armored concrete girt strip and newly-increased reinforced concrete circular important actor use are more original
The higher leveled concrete of blower foundation strength grade of concrete.
Further, the spacing between the adjacent vertical bar planting hole is 300 ~ 800mm.
Further, the spacing between the adjacent radial bar planting hole is 200 ~ 300mm.
Further, a diameter of 20 ~ 25mm of the vertical reinforcement and the radial reinforcing bar.
Blower foundation reinforcement means provided by the invention has the following advantages：（1）Newly-increased armored concrete girt strip increases
The lateral restriction of original blower foundation.（2）Newly-increased reinforced concrete circular important actor increases original blower foundation ring
Anchorage depth.（3）Newly-increased armored concrete girt strip and newly-increased reinforced concrete circular important actor and original blower foundation shape
At an entirety, to share the external loads that original blower foundation cannot undertake completely.（4）The reinforcement means of the present invention has
Construction quickly, low cost, to original blower foundation without destroy, it is with good investment the features such as.
