This is a sunken construction where square materials are built into concrete foundation blocks and gravel is poured in.
In recent years, the method of "multi-natural river development," which does not use concrete (invisible methods), has been promoted in various regions, resulting in significant effects on the conservation and restoration of habitats for diverse organisms living by the water and natural landscapes. On the other hand, riverbank protection methods are required to have comprehensive functions, including flood disaster prevention and environmental measures. To this end, Toho Giken Co., Ltd. has been working on the development and dissemination of various methods and products under the "TG-style multi-natural riverbank series," with the guidance and cooperation of related parties, and has achieved implementation results in rivers across the country. The "TG-style sunken bed method" is a sunken bed construction that combines concrete foundation blocks with natural wooden lattice materials.
