Description
Technical field
The present invention relates to a kind of photovoltaic plant being built in flyash field ground, can effectively utilize idle pulverized coal ash place to build place as photovoltaic, significantly the spending of reduction construction land.
Background technology
Pulverized coal ash receives to catch the thin ash got off from the flue gas after coal combustion, and component difference is larger.The pulverized coal ash collected is delivered to pipeline again with high pressure water flushing row by power plant, and this wet row's technique defines ash lagoon.In engineering, pulverized coal ash as material fill characteristic and compacting checking and appraising comes into one's own.
The ash quantity that power plants is discharged every year has reached more than one hundred million ton, in every industrial residue discharge capacity occupy the 4th, be wherein utilized less than 1/5th.China's ash storage yard of power plant floor space about 120,000 mu, occupies second in various waste material floor space.Along with the increase of installed capacity, the expansion utilization of fire coal low in calories and the raising of ash disposal efficiency, the pulverized coal ash discharged from now on will increase substantially.At present, some breaks rules and regulations to enter rivers,lakes and seas, due to the needs of environmental protection, must seasoning get up in the recent period, and therefore total seasoning amount increases more.So a large amount of pulverized coal ash seasonings to be got up, not only busy at putting up installations, and still likely contaminated environment, once accident also can affect the normal life of neighbouring resident.Therefore, the purposes of developing pulverized coal ash, and the seasoning problem properly settling pulverized coal ash has become outstanding socioeconomic problem all.
Why pulverized coal ash place is difficult to by engineering construction is utilized, mainly because pulverized coal ash has the engineering mechanics property being different from general soil.Fly ash grain composition is similar to flour sand, has high, the high liquid limit of void ratio, feature that natural density is low, has cohesive strength time unsaturated; After pulverized coal ash immersion, its intensity significantly reduces; In addition, pulverized coal ash easily causes environmental pollution, and soil layer has corrosivity, also makes the utilization in pulverized coal ash place comparatively difficult.
Current Domestic builds photovoltaic generation project in a large number, and photovoltaic project floor space is general very large, not high to the utilization ratio in place, discarded grey field is used as photovoltaic generation place, can reduces expropriation of land, increase economic efficiency.In addition, because the deadweight of solar components support is comparatively light, in arranged in arrays, all less to the requirement of place bearing capacity, perhaps just in time compensate for the shortcoming of pulverized coal ash place engineering properties difference.
Summary of the invention
The object of this invention is to provide a kind of photovoltaic plant being built in flyash field ground.
In order to achieve the above object, the invention provides a kind of photovoltaic plant being built in flyash field ground, comprise photovoltaic group string, box-type substation and inverter, it is characterized in that, described photovoltaic group string is located on secondary joist, secondary joist is located on main joist, main joist is located on column, column is located on photovoltaic group string basis, described box-type substation and inverter are located on box type transformer substation base and inverter basis respectively, wherein, described photovoltaic group string basis, box type transformer substation base and inverter basis are located in pulverized coal ash place.
Preferably, described photovoltaic group string basis is bar shaped.
More preferably, the buried depth d on described photovoltaic group string basis is 0.5m-0.6m.
Preferably, the connection between described photovoltaic group string and secondary joist is that point connects.
More preferably, described point connects employing spring and cushions.
Compared with prior art, the invention has the beneficial effects as follows:
The key construction being built in flyash field photovoltaic plant on the ground of the present invention is built directly in undressed flyash field on the ground, open up the purposes in pulverized coal ash place, and save and build expropriation of land needed for photovoltaic plant or leased land expense, improve economic benefit.

Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
Embodiment
A kind of photovoltaic plant being built in flyash field ground, comprise photovoltaic group string 4, box-type substation and inverter, as depicted in figs. 1 and 2, described photovoltaic group string 4 is located on secondary joist 7, secondary joist 7 is located on main joist 6, main joist 6 is located on column 5, column 5 is located on photovoltaic group string basis 1, described box-type substation and inverter are located on box type transformer substation base 2 as shown in Figure 3 and Figure 4 and inverter basis 3 as shown in Figure 5 and Figure 6 respectively, wherein, described photovoltaic group string basis 1, box type transformer substation base 2 and inverter basis 3 are located in pulverized coal ash place.Described photovoltaic group string basis 1 is bar shaped.The buried depth d on described photovoltaic group string basis 1 is 5m.Connection between described photovoltaic group string 4 and secondary joist 7 is that point connects.Described point connects employing spring and cushions.
The buried depth on described photovoltaic group string basis 1 is more shallow, the better soil layer in Flyash Layer top layer can be made full use of (during construction, top layer need through precipitation, be exposed to the sun, natural consolidation) bearing capacity is higher, quantities is little, differential settlement is less, connection between photovoltaic group string 4 and secondary joist 7 adopts spring to cushion, and differential settlement is little for the adverse effect of support and photovoltaic panel.
The method of construction of above-mentioned photovoltaic plant is:
