Abstract
The utility model relates to a foundation pressure-bearing beam plate type wind power generation tower foundation, which belongs to foundation structure of wind power generation towers. A concrete cushion layer is ring-shaped, a cushion plate is embedded in the ring-shaped concrete cushion layer, the cushion layer is provided with a concrete foundation bottom plate, the middle of the foundation bottom plate is provided with a ring-shaped concrete column pier, edge small beams are arranged close to the edge positions of the foundation bottom plate, and the column pier is connected with the edge small beams through cantilever beams to form a structure in the shape of *. Two adjacent edge small beams are connected through the cantilever beams to form a ring, an anchor bolt end of the column pier is connected with a foundation lower anchor plate, and the other end of the pier column is connected with a tower barrel. The foundation pressure-bearing beam plate type wind power generation tower foundation adopts the *-shaped beam to reduce engineering quantity of foundation concrete. Pressure-bearing area of the foundation and the groundwork is reduced, pressure stress of the ring-shaped cushion layer is increased, and pulling force of a foundation bottom face caused by bending moment of upper portion structures is resisted, thereby reducing the foundation bottom area. Foundation ring type connection of the tower barrel of the wind power generation tower and the foundation is changed into the pre-stress anchor bolt type connection. Rigid connection of the tower barrel and the foundation is guaranteed, and steel using quantity is reduced.
Description
Technical field
The utility model relates to a kind of pressure on foundation beam and slab type generation power foundation of wind power, belongs to wind power generation stepped foundation structure.
Background technology
Wind power generation stepped in basis on the hard foundation soil at present more adopts independent spread footings, this independent spread footing is made up of encorbelment base plate, stub and discharge ring of basis.Independent spread footing matches with suitable foundation condition can reach resistance to compression bearing capacity preferably, so in the housing construction base for post, employing is arranged more.But for wind power generation stepped, if it were not for pressure but moment of flexure, so the anti-pressure ability of traditional independent spread footing is had a surplus, bending resistance is not enough, thereby has caused the bigger waste of basic engineering to the active force master on basis for superstructure.
Existing wind power generation stepped independent spread footing adopts thickening degree cantilevered plate as sole plate more, because the basic plane size is big, the length of encorbelmenting of plate is big, and the stressed back of outrigger base structure effect is very big, so the basis is uneconomical, invests bigger.
Summary of the invention
The purpose of the utility model is to provide a kind of pressure on foundation beam and slab type generation power foundation of wind power that strengthens bending resistance.
The utility model comprises: concrete cushion, concrete foundation base plate, semi girder, edge girder, concrete stub, prestressing force crab-bolt, soft backing plate, and concrete cushion is annular, and annular bed course center is embedded with soft backing plate; Bed course and soft backing plate are provided with concrete foundation base plate; The middle part of concrete foundation base plate is provided with annular concrete stub, and the concrete foundation base plate place of keeping to the side is provided with the edge girder, in order to strengthen bending resistance; The concrete stub is connected through semi girder with the edge girder; Form the M shape structure, two edge girders that face mutually link together through semi girder, form annular; Evenly bury the prestressing force crab-bolt in the concrete stub underground, prestressing force crab-bolt one end is connected with basic anchor slab down, and the other end is connected with the tower tube.
Said soft backing plate adopts foamed polystyrene board.
Edge girder and semi girder are respectively 8.
Semi girder of the utility model and stub and edge girder,
The utility model earlier with the annular concrete cushion in the intracardiac soft backing plate of inlaying contact; Increase along with compressive stress; Soft backing plate sink; Concrete foundation base plate is contacted with the annular concrete bed course, and soft backing plate is a liner, can not make sole plate center and ground transmit compressive stress.Because the basis reduces with the actual bearing area of ground, the compressive stress on the basic annular compression face has increased, and can be used for resisting the pull out force that the superstructure moment of flexure causes foundation bed, thereby reduces foundation ' s bottom area.
The utility model as main bending resistance component, and surrounds the base center tube of wind-power electricity generation Tata tube with rice word depth of beam with beam, to reduce the engineering quantity of base concrete.
The utility model changes wind-power electricity generation Tata tube and being connected by basic ring type of basis into prestressing force crab-bolt formula.Guarantee tower tube and basic being rigidly connected, reduced steel using amount, also simplified the construction of this part simultaneously.
