Description
Technical field
The utility model belongs to wind turbine tower field, is specifically related to a kind of tower foundation for wind-power electricity generation precast concrete pylon.
Background technology
The sternness of global energy anxiety and amblent air temperature problem, impels the development and utilization of various countries' pay attention to day by day to regenerative resources such as wind energies.The wind speed of hinterland is conventionally much lower than coastal area, for the wind energy turbine set in low wind speed area in giving provides more generated energy, there are two kinds of main selections in blower fan supplier: they both can select to install the blower fan with larger wind wheel, also can be not having transformed unit to be arranged on higher wind tower.The selection of high tower only need increase appropriate investment, just can significantly improve power stage.Because limitation and the cost of steel tower material behavior have determined the inevitable of high concrete pylon, the cast-in-situ concrete pylon construction period is longer, is difficult to meet wind field rapid construction requirement, and precast concrete pylon arises at the historic moment.
Concrete blower fan pylon comprises whole concrete pylon and steel+concrete mixing pylon, and whole concrete pylon structure has that size is large and weight is large, transports and lift long in time limit, cost is large, and rigidity is large, and power performance is good, the features such as anti-fatigue performance is good, the low and good endurance of maintenance cost; Steel+concrete mixing pylon has, and size is less, weight is less, convenient transportation, the feature such as hoisting cost is low, and the duration is short.Precast concrete pylon is connected with tower foundation, because tower foundation adopts cast-in-place concrete structure mostly, be subject to the impact of wind field mal-condition, cannot ensure the planeness of basic end face, therefore, adopt the form that transition member is set, by adjusting the planeness of transition member, dock with the concrete pylon on top, to ensure the required precision of pylon and base water plane.Visible, transition member is the key that ensures pylon and basic good contact, adopts this kind of precast concrete transition member, has balance adjustment convenient, fast, and the advantages such as precision height.
Utility model content
The purpose of this utility model is to provide a kind of tower foundation coordinating with concrete pylon, improves splicing prefabricated components precision, accelerates the assembled progress of prefabricated units, saves time, and construction method is simple, a kind of pylon of easy construction and basic type of attachment.
The purpose of this utility model is achieved in that a kind of tower foundation for wind-power electricity generation precast concrete pylon, tower foundation lower interior is built the supporting steel frame flushing with tower foundation soffit, tower foundation upper interior build with tower foundation upper surface flush and with the annular connecting elements of pylon soffit adaptation, lateral adjustments jack and vertical adjustment jack are installed between described supporting steel frame and annular connecting elements.
Described supporting steel frame is made up of supporting steel frame one and supporting steel frame two; Described lateral adjustments jack is fixed on the side of annular connecting elements and is supported on supporting steel frame one, and vertical adjustment jack is fixed on the bottom of annular connecting elements and is supported on supporting steel frame two.
Described supporting steel frame has three groups at least, and is uniformly distributed around the center of circle of annular connecting elements below.
On described annular connecting elements, be evenly equipped with prestress hole.
technique effect of the present utility model and advantage:
The utility model ensures that by annular syndeton is set pylon and basis are connected into entirety, then ensure that by grouting form member forms entirety.Arrange connecting elements can ensure pylon with basis good connection, accelerate component assembly progress, improve merging precision, construction method is simple, convenient, save the time, ensured that prestressing with bond rope anchor head is well connected with basis with external prestressing tendon anchor head, has stronger actual application value simultaneously.
