Description
Technical field
The invention belongs to generation power foundation of wind power technical field of structures, and in particular to one kind is for reinforcing blower foundation connection
Conversion method for supporting.
Background technique
It is connect with bottom reinforcement bars concrete foundation currently, single tube is wind power generation stepped frequently with pre- in reinforced concrete foundation
Foundation ring, top tower and foundation ring is buried to realize by flanged joint.However, since foundation ring length of embedment is shallow, and be non-pre-
Stress structure connects top tower using foundation ring and base foundation has the following deficiencies: that the existing reinforcing bar of basic ring region has again
Foundation ring is reinforced, and following region only has reinforcing bar, causes to generate because of concrete hardening contraction and stress because of strength and stiffness mutation
Crack concentrates between foundation ring and bottom plate, and fracture width increases；Foundation ring isolates inside and outside concrete, due to steel and concrete
Two kinds of material property differences, thermal expansion coefficient is different, deformation cannot be coordinated, and temperature action, load work, frost heave action etc. make basis
The gap of ring and concrete is continuously increased, and deteriorates the anchorage effect of the two；Under blower reciprocating fatigue load action, foundation ring connection
Region distress in concrete, gap are continuously increased development, and then foundation ring is made to vibrate, rock in base concrete, generate to mixed
Coagulate the percussion of soil.
Basis connects the existing stress defect project problems that cause to have put into operation and gradually breaks out, and seriously affects the fortune of blower
Row quality and operational safety.
Summary of the invention
The purpose of the present invention is to provide a kind of for reinforcing the conversion method for supporting of blower foundation connection, can be used for
Build up the reinforcing for the item base ring Joint failure that puts into operation.
Proposed by the present invention a kind of for reinforcing the conversion method for supporting of blower foundation connection, the conversion method for supporting is logical
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
4 composition of support, the foundation ring 1 are inserted into concrete stub 2, and basic circumferential weld is equipped between the foundation ring 1 and concrete stub 2
Gap area 3；When connecting setting conversion support 4 to basis, the specific steps are as follows:
(1) several grout holes 5 are drilled through in the two sides that foundation ring 1 is located at 2 inner part of concrete stub, makes the grout hole 5
Lead to foundation ring slit region 3；
(2) fill out foundation ring slit region 3 and grout hole 5 all 3 pressure grouting of foundation ring slit region by grout hole 5
Full of high-strength grouting material；
(3) several vertical drillings 6 are arranged on the outside of foundation ring 1, vertical 6 bottoms that drill are drilled into foundation ring 1；Then perpendicular
The arrangement conversion support 4 into drilling 6, and the gap grouting 7 between vertical drilling 6 and conversion support 4 of constructing；Under conversion support 4
End holds out against foundation ring 1, so that foundation ring 1 is largely forced through conversion support 4 and is transferred to 2 top Elevated section concrete 9 of stub,
The stress for reducing 1 bottom of foundation ring is concentrated, and the bearing capacity and anti-fatigue performance of concrete are improved；
(4) vertical bar planting 8 is arranged in the top surface of concrete stub 2 and increase concrete 9.
In the present invention, the conversion support 4 is made of steel member 10 and the end plate 11 being welded at the top of steel member, end plate 11
Expose 2 certain altitude of concrete stub, is anchored in and increases in concrete 9.
The beneficial effects of the present invention are:
1. proposed by the present invention a kind of for reinforcing the conversion method for supporting of blower foundation connection, structure is simple, stress is closed
Reason can be used for being completed the reinforcing for the item base ring Joint failure that puts into operation.
2. when setting conversion support, making foundation ring largely be forced through conversion support and being transferred to Elevated section at the top of stub
Concrete, the stress for reducing foundation ring bottom are concentrated, and the bearing capacity and anti-fatigue performance of concrete are improved.
3. the present invention is for being completed the reinforcing for the item base ring Joint failure that puts into operation, ring beam is thickeied in conjunction with top and is arranged
It applies, the buried depth of foundation ring can be increased, improve concrete to the binding effect of foundation ring, and do not destroy original structure.
4. operation of the present invention is convenient, easy for construction.
Detailed description of the invention
Fig. 1 is that basis of the present invention connects main view.
Fig. 2 is the main view that the present invention applies.
Fig. 3 is the top view that the present invention applies.
Figure label: 1 it is basic ring, 2 is concrete stub, 3 is basic ring slit region, 4 is to convert 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.
Specific embodiment
The present invention is further illustrated below by embodiment combination attached drawing.
Embodiment 1:
As shown in Figure 1, between foundation ring 1 and concrete stub 2, generating foundation ring gap area when basic Joint failure
3。
When the present invention is applied to reinforce blower foundation connection, it is located at the two of 2 inner part of concrete stub in foundation ring 1 first
Sidetracking takes several grout holes 5, and the grout hole 5 is made to lead to foundation ring slit region 3；Then by grout hole 5 to foundation ring gap
3 pressure grouting of area makes foundation ring slit region 3 and grout hole 5 be stuffed entirely with full high-strength grouting material；Then the cloth on the outside of foundation ring
Several vertical drillings 6 are set, vertical 6 bottoms that drill are drilled into foundation ring 1；Then the arrangement conversion support 4 in vertical drilling 6, and
Gap grouting 7 between the vertical drilling 6 of construction and conversion support 4；Finally, arranging vertical bar planting 8 in the top surface of concrete stub 2
And increase concrete 9.The conversion support 4 is made of steel member 10 and the end plate 11 being welded at the top of steel member, and end plate 11 reveals
2 certain altitude of concrete stub out is anchored in and increases in concrete 9.
Implementation steps are as follows:
