Wuhan Wuhan Uses Spectral Technology to Realize Forest Soil Prediction
Crawler type piling rig,Solar piling drill rigs is widely used in photovoltaic, foundation drilling, it is most advanced hydraulic drilling rig for solar drilling application. The rig can be operated in very flexible way.
As per the emission standard which requires a quality and better emission diesel engine in most of European countries and North America,the customized-made PV piling rig will be the unique solution
The feed can be turned left and right in different angle to fit the variable application. The full coverage area for drilling is seriously considered to achieve extremely drilling position. For solar power station, Photovoltaic drilling, pile drilling and highway guardrail drilling as well as construction drilling is most suitable.
Solar pile driver has some unique design to has it to operate in every sharp slope area and in order to make operator a very vertical borehole in any position.
Yikyui PV pile driver has rotary boom with rotary platform. With this function, operator can drill in very accurate position with less moving of Pile drilling machine, which can save time and higher quality borehole.

Quickly, cheaply and accurately obtaining information on carbon (C) and nitrogen (N) content in soil is the basis and premise for the current assessment of soil quality and management of the global soil carbon pool revenue and expenditure, and the spatial heterogeneity of soil has increased people’s The difficulty and cost of dynamic monitoring of soil properties.
Forest soil is an important basis for regulating the carbon balance of terrestrial ecosystems. The use of near-field hyperspectral remote sensing technology to achieve fast, efficient, non-destructive, and cost-effective modeling of multi-level forest soil C and N content is expected to open up new avenues for current research on soil C and N dynamics and mapping. Helping to deepen the understanding of the spatial heterogeneity of soil C and N and influencing factors is of great significance for the management and sustainable management of forest soil carbon pools. However, due to the influence of the soil layer, the prediction ability of the hyperspectral inversion model of soil properties is reduced, which limits the application of the model.
Jiang Qinghu, assistant researcher at the Wuhan Botanical Garden of the Chinese Academy of Sciences under the guidance of researcher Liu Feng, used the soil of different layers in the mid-subtropics (Badaminggongshan) forest as an example to establish surface and subsurface soil organic carbon (SOC) and total nitrogen in the area using spectroscopic techniques. (TN) spectral inversion prediction model, so as to achieve rapid prediction of high heterogeneity forest SOC and TN. Among them, the R2 of the spectral model predicted by SOC is 0.79-0.90, and the R2 predicted by TN is 0.66-0.86. On the basis of this, it is difficult to implement the transferability between layers in the model. Using the spiking method and the weighted algorithm, this problem is solved successfully, and the transitivity of the predictive model is greatly improved. The development of this research provides potential for rapid acquisition of high heterogeneity soil property information.
The study was supported by the National Natural Science Foundation of China (31270515, 31470526) and the National Key Basic Research Development Plan (2014CB954004). The results were based on the estimation of soil organic carbon and total nitrogen in different soil layers using VNIR spectroscopy: Effects of spiking on model applicability. The question was published in Geoderma magazine.

Besides piling drilling, it can do blasting hole drilling for mining.
It is fully hydraulic control solar piling machine, it can has highest drilling efficiency for operator, especially for time limited project. And the key components are from top end brand, such as Deutz AG diesel engine,Cummins engine, Yuchai diesel engine,Permco pump,Eton motor, Parker hoses and Rexroth pump. All these key components can make sure solar pile driving Machine has longest lifetime and least break down.
The Photovoltaic rig`s drilling model can be selected from impact hammer to rotary head for different geological structure.
Photovoltaic pile driver is not only for photovoltaic or soloar piling drilling, it also can work for water drilling and foundation drilling etc. multi-functional drilling work.
