Description
Technical field
The utility model is related to photovoltaic bracket technical field, especially a kind of scalable piling bar of novel static pressure.
Background technology
National Energy Board gives out information title on the 2nd, and by the end of the year 2015, Chinese photovoltaic generation adds up installed capacity
43.18GWp, as the country that global Photovoltaic generation installed capacity is maximum.Wherein, photovoltaic plant 37.12GWp, it is distributed
6.06GWp, the kilowatt hour of annual electricity generating capacity 39200000000.
Data display, 15,130,000 kilowatts of adding new capacity in 2015 completes the newly-increased grid-connected installation 1500 of 2015 years
It is more than ten thousand kilowatts of target, a quarter for accounting for the newly-increased installation in the whole world.Wherein large-scale ground power station project is more used pre-
/ the form such as stake is buried, is fixed by bolt with stake.Support and component etc. will not be caused with sleety weather to hinder to damage blowing
Mistake does not interfere with the generating of its own yet.
Ground photovoltaic bracket installs the main distinction in fixed form, according to the current feelings that photovoltaic plant is built both at home and abroad
Condition, power plant bracket system technique for fixing scheme mainly has three classes, as follows：
Scheme one, pre-buried scheme：Earth excavation is carried out in advance, and built-in fitting is implanted into soil by cast-in-place concrete, it is early
Phase this form is using more.
Scheme two, spiral ground pile：Screw pile is implanted into soil by this programme by supporting machine, and construction cost is higher, unfavorable
In popularization and application.
Scheme three, precast static pressure pile：By pre-cast concrete stake, prefabricated pile is implanted into special-purpose machinery depended on pressure when to be used
In soil.
The defect of scheme one：This programme long construction period, built-in fitting need to individually excavate pre-buried, and earth volume is larger.
Scheme two, the problem defect of scheme three：The characteristics such as corrosive nature, high density, frost heaving resistant, wind resistance, will strictly consider stake
Bearing capacity and service life.Spiral ground pile, prefabricated pile etc. are in corrosion resistance, fitful wind, surface soil high humidity, and adhesion strength is not
Enough wait under specified conditions, easily betide situations such as pile foundation departs from, influence generating equipment safety, and then influence power plant normally to produce.
