Abstract
The invention discloses a tower foundation of a wind driven generator on land, which adopts the tower foundation of the wind driven generator combining a gravity type extended base and a single-column, comprehensively utilizes the lateral thrust resistance of landfill soil, the structure of the lateral thrust resistance and the dead weight of the landfill soil to bear the dead weight and the overturning load of the tower of the wind driven generator, and has the characteristics of strong bearing capacity, simple structure, convenient construction and economic construction cost.
Description
[technical field]
The present invention relates to building field, especially a kind of tower foundation that is used for the wind-driven generator of land.
[background technology]
At present, the tower foundation of the wind-driven generator of land comprises gravity spread footing, beam and slab type basis or independent pillar basis.Main deadweight and the overturning moment thereof that utilizes bigger foundation bed to bear wind-driven generator and pylon of gravity spread footing and beam and slab type basis; Insert in the foundation soil on independent pillar basis, utilizes the anti-side-thrust opposing wind-driven generator of foundation soil and the overturning moment of pylon.Continuous increase along with the wind-power electricity generation acc power; The volume of wind-driven generator and pylon and weight thereof are also along with increase; The also corresponding increase of load that the tower foundation of wind-driven generator is suffered, gravity expanded type basis and beam and slab type basis then need increase the base plate diameter with the bigger overturning moment of opposing.For this gravity spread footing, the section area that must increase thickness of slab or beam is to satisfy the anti-shearing and moment of flexure requirement of structure; Independent pillar basis then need increase the landfill degree of depth, and with the bigger overturning moment of opposing, but darker ground has increased the field engineering amount, thereby increases construction costs.
[summary of the invention]
The technical problem that the present invention will solve provides a kind of tower foundation that adopts the wind-driven generator that the gravity spread footing combines with insulated column; The anti-thruster ability that has fully utilized landfill soil is born the deadweight of wind-driven generator tower frame and the load that topples thereof with the deadweight of its structure and landfill soil; It is strong to have supporting capacity; Simple in structure, the characteristics of easy construction and construction costs economy.
For solving the problems of the technologies described above; A kind of tower foundation that is used for the wind-driven generator of land of the present invention comprises the gravity spread footing, and said gravity spread footing is provided with the insulated column that cross section is toroidal; Said gravity spread footing is for mixing the earth base plate; Said insulated column is for mixing the earth bar construction, and said insulated column inside comprises that some prestressed anchors and several and prestressed anchor constitute the reinforced steel of steel work, and said prestressed anchor is provided with and stretches out the link that the insulated column top is used to connect pylon; Said reinforced steel is for being parallel to the insulated column cross section, and the annular ring that is fixedly connected with prestressed anchor; The distributed number of said prestressed anchor and reinforced steel is determined by the environment on basis and the size and the load thereof of insulated column.
Junction between said gravity spread footing and the insulated column is provided with the semi girder of the some insulated columns that are circularly and evenly distributed and are surrounded on; Said semi girder bottom is connected with the gravity spread footing; Said semi girder sidewall is connected with insulated column; Be fixedly connected with the edge girder between said semi girder is adjacent, said edge girder is fixedly connected into polygonized structure; According to condition of construction at the scene, said semi girder can be preferred 4 or 5 or 6 or 8 four kinds.
The bearing capacity of gravity of said gravity spread footing dependence own and following soil for sleeping in comes axial force and the moment of flexure of role-taking in gravity spread footing top, and horizontal force is born by the frictional resistance of gravity spread footing and the soil for sleeping in below it; Native horizontal bearing capacity of landfill carried suffered horizontal loading and moment of flexure around said insulated column relied on it.
A kind of tower foundation that is used for the wind-driven generator of land of the present invention; Adopt gravity spread footing and insulated column structure combining; The anti-thruster ability that has fully utilized landfill soil is born the deadweight of wind-driven generator tower frame and the load that topples thereof with the deadweight of its structure and landfill soil; It is strong to have supporting capacity, simple in structure, the characteristics of easy construction and construction costs economy.
