守谷商会 of Nagano City used 3D-printed blocks at a worksite and shortened the construction period for a gravity retaining wall at a water distribution reservoir site in Iizuna from approximately 2 weeks to 1 month to about 2 days.
守谷商会 (Nagano City) carried out construction at a worksite in Iizuna using 3D-printed blocks designed to follow the site's terrain. The project involved installing a gravity retaining wall on the premises of a water distribution reservoir.
The use of 3D-printed blocks improved the fit of components to the site's shape and was said to have shortened the construction period compared with conventional concrete products. The construction period had been expected to be approximately 2 weeks to 1 month, but a shortening effect is expected.
オーイケ (Yamagata Village, Higashichikuma District), a manufacturer of concrete products, was responsible for producing the blocks, and the supply and installation of 3D-printed components at the site are believed to have proceeded. The technology may be considered for use at similar worksites in the future.
