オクノコトー List of Products and Services

This construction method involves separating "topsoil" into grass roots, stems, and soil, and is a technology for reusing soil. More than 90% of the topsoil before separation can be utilized as fill material or backfill material. The rotating drum of the topsoil separation device has a "crushing area" and a "separation area," where the topsoil is crushed and then separated into soil and grass roots and stems. 【Features】 - Reduction in the number of transport vehicles to disposal sites and reduction in CO2 emissions - Applicable soil types include sandy topsoil and clayey topsoil (soil classification CL・ML) - By supplying a fixed amount from the soil hopper, the separation effect is enhanced and the amount of processed soil is stabilized - The rotating drum of the topsoil separation device has a "crushing area" and a "separation area" - Quicklime can be added simultaneously, allowing for soil quality improvement *For more details, please refer to the PDF materials or feel free to contact us.

This technology combines and processes two or three types of construction-generated soil with different soil properties through mixing treatment (particle size adjustment and strength improvement) to produce quality embankment materials suitable for various applications. By utilizing this technology, it is possible to effectively use "poor soil" that was previously disposed of, and since soil quality improvement is conducted between natural soils, there is no negative impact on the natural environment. 【Features】 - No possibility of leaching of alkaline components or hexavalent chromium, thus no adverse effects on the natural environment. - Generated soil can be recycled as embankment material. - Being homogeneous improves workability during embankment construction. - Usable immediately after mixing treatment. - Particle size adjustment and compaction allow for the construction of soil structures without issues related to re-excavation. *For more details, please refer to the PDF materials or feel free to contact us.
