Conversion method for supporting.
Background technology
At present, single tube is wind power generation stepped is connected with bottom reinforcement bars concrete foundation frequently with pre- in reinforced concrete foundation
Bury foundation ring, top tower is connected realization with foundation ring by flange.However, because foundation ring length of embedment is shallow, and be non-pre-
Stress structure, top tower is connected using foundation ring and base foundation has following defect：The basic existing reinforcing bar of ring region has again
Foundation ring is strengthened, and region below only has reinforcing bar, because strength and stiffness mutation causes because caused by concrete hardening contraction and stress
Crack is concentrated between foundation ring and bottom plate, fracture width increase；Foundation ring isolates inside and outside concrete, due to steel and concrete
Two kinds of material property differences, thermal coefficient of expansion is different, deformation can not be coordinated, and temperature action, load work, frost heave action etc. make basis
The gap of ring and concrete is continuously increased, and deteriorates both anchorage effects；Under blower fan reciprocating fatigue load action, foundation ring connection
Region distress in concrete, gap are continuously increased development, and then foundation ring vibrated, rocked in base concrete, produce to mixed
Coagulate the percussion of soil.
The project problems that cause to have put into operation of stress defect existing for the connection of basis gradually break out, and have a strong impact on the fortune of blower fan
Row quality and safe for operation.
The content of the invention
It is an object of the invention to provide a kind of conversion method for supporting for being used to reinforce blower foundation connection, can be used for
Build up the reinforcing for the item base ring Joint failure that puts into operation.
A kind of conversion method for supporting for being used to reinforce blower foundation connection proposed by the present invention, the conversion method for supporting lead to
The realization of conversion support component is crossed, the conversion support component is by foundation ring 1, concrete stub 2, foundation ring slit region 3 and conversion
The composition of support 4, the foundation ring 1 insert concrete stub 2, basic circumferential weld are provided between the foundation ring 1 and concrete stub 2
Gap area 3；When connecting setting conversion support 4 to basis, comprise the following steps that：
（1）The both sides for being located at the inside points of concrete stub 2 in foundation ring 1 drill through some grout holes 5, lead to the grout hole 5
Foundation ring slit region 3；
（2）By grout hole 5 to the pressure grouting of foundation ring slit region 3, foundation ring slit region 3 and grout hole 5 is set to be stuffed entirely with completely
High-strength grouting material；
（3）Several vertical drillings 6 of arrangement in the outside of foundation ring 1, vertical 6 bottoms that drill are drilled into foundation ring 1；Then vertically boring
Arrangement conversion support 4 in hole 6, and the gap grouting 7 between vertical drilling 6 and conversion support 4 of constructing；4 lower ends of conversion support top
Tight foundation ring 1, the major part of foundation ring 1 is forced through conversion support 4 and be transferred to the top Elevated section concrete 9 of stub 2, reduce
The stress concentration of the bottom of foundation ring 1, improve the bearing capacity and anti-fatigue performance of concrete；
（4）Vertical bar planting 8 is arranged in the top surface of concrete stub 2 and increases concrete 9.
In the present invention, the conversion support 4 is made up of steel member 10 and the end plate 11 being welded at the top of steel member, end plate 11
Expose the certain altitude of concrete stub 2, be anchored in and increase in concrete 9.
The beneficial effects of the present invention are：
1. a kind of conversion method for supporting for being used to reinforce blower foundation connection proposed by the present invention, simple in construction, reasonable stress can
For being completed the reinforcing for the item base ring Joint failure that puts into operation.
2. conversion support is set, foundation ring is largely forced through conversion support and be transferred to Elevated section at the top of stub
Concrete, reduce the stress concentration of foundation ring bottom, improve the bearing capacity and anti-fatigue performance of concrete.
3. the present invention is used to be completed the reinforcing for the item base ring Joint failure that puts into operation, thickeies ring beam with reference to top and arrange
Apply, the buried depth of foundation ring can be increased, improve binding effect of the concrete to foundation ring, and do not destroy original structure.
4. simple operation of the present invention, easy for construction.
Brief description of the drawings
Fig. 1 connects front view for basis of the present invention.
Fig. 2 is the front view that the present invention applies.
Fig. 3 is the top view that the present invention applies.
Label in figure：Ring based on 1,2 be ring slit region based on concrete stub, 3,4 be to change support, 5 as grouting
Hole, 6 for vertical drilling, 7 be gap grouting, 8 be vertical bar planting, 9 for increase concrete, 10 be steel member, 11 be end plate.
Embodiment
The present invention is further illustrated below by embodiment combination accompanying drawing.
Embodiment 1：
As shown in figure 1, during basic Joint failure, between foundation ring 1 and concrete stub 2, foundation ring gap area 3 is produced.
When the present invention is applied to reinforce blower foundation connection, it is located at the two of the inside points of concrete stub 2 in foundation ring 1 first
Sidetracking takes some grout holes 5, the grout hole 5 is led to foundation ring slit region 3；Then by grout hole 5 to foundation ring gap
