Research on Jakago technology being promoted by a research team of Professor Tadashi Hara of the Department of Natural Sciences, Faculty of Education and Research, Kochi University, Professor Hiroshi Nakazawa of the Department of Civil Engineering, Shizuoka University of Science and Technology, and Professor Daisuke Suetsugu of the Faculty of Engineering, Miyazaki University. And the efforts for dissemination received the Excellence Award at the STI for SDGs Awards of the Japan Science and Technology Agency.
The gabion technology that the team is working on researching and disseminating is a construction method in which structures filled with stones are stacked in a reinforcing bar cage and used in various civil engineering works such as retaining walls on roads.It is a traditional civil engineering technology, and although it is not the latest method, it is expected to spread to developing countries where the development of disaster prevention infrastructure is delayed because it can procure materials at low cost and does not require so high technical ability for construction. Has been done.
The team quantitatively analyzed the seismic resistance of the gabion, clarified it with scientific knowledge, selected materials to improve the seismic resistance, specified the design and construction method, and made efforts to spread it not only in Japan but also overseas. ..
The STI for SDGs Award is an award given to outstanding efforts to solve social issues using Science, Technology and Innovation (STI), and was established by the Japan Science and Technology Agency in FY2019.The team's award was highly evaluated for its high sustainability of gabion technology and the fact that it can be constructed with the participation of residents amid the increasing number of large-scale disasters such as floods.
