Description
Technical field
The present invention relates to generation power foundation of wind power reinforcement technique field, and in particular to a kind of foundation ring Rock Bolt Foundation.
Background technology
Wind-power electricity generation is as field of renewable energy is the most ripe, generating of most large-scale development and business development condition
One of mode, turn into the important directions of Renewable Energy Development gradually, particularly in the Inner Mongol, Gansu, Xinjiang, Hebei and river
The planning of the abundant regional 6 ten million KW level wind power bases of the wind energy resourceses such as Soviet Union, also fully demonstrate the bright prospects of wind-powered electricity generation cause.
But with the large-scale development of wind power plant, difficulties and problems of the blower fan in process of construction have also obtained progressively exposing, wherein it
One is exactly the degree of stability of blower foundation, anti-pulling degree.
Blower foundation be by steel loop and coagulation local soil type into steel-concrete combined structure, blower foundation ring is the important of blower foundation
Part, huge wind-force effect will be unavoidably born as the tower body of supporting construction and basis, and blower foundation ring will be held
By all kinds of loads for passing to basis by steel loop from blower fan pylon.
Wind-power market has certain occupation rate to flush type tower barrel base at home at present.However, the embedment of foundation ring is deep
Degree is limited by depth of foundation, causes buried section buried foundation excessively shallow, only about 0.3~0.4 times of blower fan tower barrel diameter.
And according to《Code for design of steel structures》(GB50017-2003) the 8.4.15 articles, plug-in type suspension column insertion minimum-depth is 1.5d (d
For the external diameter of tubular pillar), and practical basis ring length of embedment is only 0.3d~0.4d far less than 1.5d.Due to foundation ring embedment
The depth, the bending resistance that foundation ring side force provides is than relatively limited.It can be led during this excessively shallow length of embedment in foundation ring basis
The destruction caused by because of fatigue load of cause foundation ring, the crack of structure safety is had an impact at the part of basis embedment.As
A kind of special steel reinforced concrete structure, foundation ring and concrete, due to two kinds of material property differences, become during carrying
Shape can not be harmonious.Under the repeated action of fatigue load, the bond stress between foundation ring and concrete disappears with vibration
Lose, disengaged between foundation ring and basis；Under tower compression percussion local failure occurs for leeward side surface of base concrete.
In using foundation ring basis, foundation ring and basic connection effect are poor, can make when load is larger foundation ring from
Foundation ring is extracted in basis, while the reinforcing bar being connected with foundation ring is pulled off.Therefore, it is necessary on the basis of prior art
On, design research and development are a kind of reasonable in design, the foundation ring basis of firm stable.
The content of the invention
It is an object of the invention to provide a kind of foundation ring Rock Bolt Foundation, has reasonable in design, firm stable etc.
The foundation ring Rock Bolt Foundation of advantage.
The purpose of the present invention is to be achieved through the following technical solutions：
A kind of foundation ring Rock Bolt Foundation, including the foundation ring basis formed by concrete are mixed on the outside of it with being sleeved on
Solidifying soil padding, the foundation ring basis and concrete cushion are columned solid construction, the top on the foundation ring basis
Provided with foundation ring, steel reinforcement cage is fixed with inside and outside the foundation ring, is set between the steel reinforcement cage and concrete cushion
There is middle steel form, the inner side setting-in of the steel reinforcement cage is provided with interior steel form, in using foundation ring basis, foundation ring and basis
Connection effect is poor, when load is larger foundation ring can be made to be extracted from foundation ring basis, while the reinforcing bar being connected with foundation ring is equal
Being pulled off, this structure significantly improves the globality on basis, and internal layer template firmly binds round foundation ring in cylinder with middle level template,
The anti-side rigidity of foundation ring surrounding concrete, while the reinforcing of steel reinforcement cage are improved, the depth of burying of foundation ring is added, also increases
The contact area of foundation ring and concrete, improve the steadiness and pull resistance of foundation ring.
Further, as one kind can embodiment, the outer sheath of the concrete cushion is equiped with outer steel mould plate, described
Concrete cushion is provided with along the equally distributed high-strength grouting post of its bottom surface extension, is mixed described in the high-strength grouting post vertical connection
Soil padding is coagulated, an anchor pole is coaxially disposed in the high-strength grouting post, the anchor pole is through the concrete cushion and passes through pressure
Power grouting is fixed in the high-strength grouting post.
Further, as one kind can embodiment, be additionally provided with and some surround the interior equally distributed transverse direction of steel form
Support bar, the transverse support bar extend transversely through the interior steel form, and the transverse support bar has sequentially passed through interior from inside to outside
Steel form, foundation ring, middle steel form, concrete cushion, outer steel mould plate, transverse support bar is the concrete separated by middle steel form
Connection, monolithic concrete structure is formed, transverse support bar passes through the hole reserved in the side of foundation ring, improves the anti-of foundation ring
Ability is pulled out, while plays the effect of the stress cage bar of tension resistance, both ends remove colligation from using circular bloom substitution bending reinforcing steel bar
Process, reduce the duration, save reinforcing bar amount, easily form the production of Standard capacity metaplasia.
Further, as one kind can embodiment, the steel reinforcement cage includes the transverse direction that is welded to connect with the foundation ring
Reinforcing bar, the equal vertical connection longitudinal reinforcement in both ends of the transverse steel.
Further, as one kind can embodiment, in addition to multiple steel hoops, the multiple steel hoop cover respectively
Mounted in the outside of the longitudinal reinforcement and inner side.
Further, as one kind can embodiment, between the transverse steel, longitudinal reinforcement, multiple steel hoops
It is welded to connect.
Further, as one kind can embodiment, the outer steel mould plate, middle steel form and interior steel form are ripple
Cylinder, outer steel mould plate, middle steel form are assemblied to form with interior steel form by multiple subtemplates.
Further, as one kind can embodiment, the cylinder cushion cap by C35-C40 labels coagulation local soil type into
Concrete support structure.
Beneficial effects of the present invention are：
1st, the present invention increases the connection of foundation ring and base concrete by the equal welded reinforcement cage inside and outside foundation ring
Property, the depth of burying of foundation ring is also increased, to improve the steadiness that foundation ring is embedded in foundation ring basis, adds basis
