Case7
The world’s largest underground space
- Contribution to the Hyper-Kamiokande -
In November 2022, excavation work for the main cavern of the Hyper-Kamiokande experiment, which follows from the Kamiokande and Super-Kamiokande experiments that led to the Nobel Prize in Physics, began in Kamioka-cho, Hida City, Gifu Prefecture.
The Hyper-Kamiokande experiment is an international collaborative research project with the goal of understanding the evolution of the universe and the fundamental laws of elementary particles.
As a design consulting company, TEPSCO has abundant experience and technical expertise in integrated information-based design technology, which encompasses the geological assessment, analysis, design, and cavern monitoring techniques we have developed through the construction of large-scale underground caverns for purposes such as underground power plants and LPG storage. In the context of the Hyper-Kamiokande excavation project, which involves the creation of the world’s largest underground space, we are collaborating with our client to make technical proposals on design and construction that place a premium on safety, reliability, and cost efficiency. Working hand in hand with the construction companies, we are contributing to laying the groundwork for technological innovation through this project.
