| Application of Stainless Steel for Dori-kamu Foundation-Making Method (Foundations
for Solar Panel Mounts) |
 |
|

Reason for selection:
Dori-kamu Foundation-Making Method is a method using steel containers loaded with heavy substances like stones and soil as the foundations for solar panel mounts, which can be placed irrespective of the environment and conditions of the ground. Dori-kamu method has such advantages as omission of soil/stratum surveys and shortened construction time over the common practice using pilings.
The mega-solar system shown in the pictures was installed in a coastal area subjected to chloride attack and considering the corrosion resistance and durability required of the material, stainless steel has been adopted for the first time. Of various stainless steel types, NSSC FWR Series (Equivalent to SUS430LX), a resource-saving type, has been selected, which, along with the generation of renewable solar energy, is expected to make huge contributions to reduce burdens on social environment.
The combination of the Dori-kamu method and the selection of stainless steel type suited to withstand any given corrosive environment will make it possible to install a solar power generation system where it was extremely difficult with conventional construction methods. Thus, the demand for the Dori-kamu foundation preparation method using stainless steel is expected to rise in the future. |
