JFEミネラル 環境プロジェクト部
In March 2021, we received notification from the Independent Administrative Institution Railway Construction and Transport Facility Maintenance Support Organization regarding the results of the public recruitment for "Construction Methods (Materials) to Reduce Shinkansen Railway Construction Costs."
The JiT mat was evaluated positively in all selection criteria of novelty, versatility, and effectiveness.
- It has a proven track record in other projects and is considered a novel technology applicable to the acceptance sites for excavated soil in Shinkansen construction.
- It is believed to have a certain level of versatility in tunnel construction for the Shinkansen.
- It is expected to be effectively utilized not only at the acceptance sites for excavated soil but also in temporary storage areas within yards during emergencies.
- Compared to water-proofing containment methods and other adsorption mat methods, it is expected to have cost advantages.
The JiT mat is a convenient mat that adsorbs heavy metals from leachate and prevents the spread of contamination. Since its development in 2015, it has been used across the country, from Hokkaido in the north to Kyushu in the south, in public works such as tunnel construction and dredging, as well as various environmental conservation efforts by private companies.
We will continue to provide technologies and materials that can be of assistance in various fields, starting with Shinkansen construction projects.
