Origami bridge helps with natural disasters

His mastery of the art of origami helped scientists from Hiroshima University to develop an original design for a mobile bridge. The development team led by Dr. Ichiro Iroh demonstrated a working model of the 4th version of the mobile bridge by throwing it across the Hongo River in Fukuyama City. The show was held as part of a symposium of the Japanese Society of Civil Engineers.

For deployment, the structure does not require the construction of a foundation or the presence of lifting mechanisms. When folded, the mobile bridge is transported on a trailer, and if necessary, it unfolds like an accordion-folded paper tape. The process of organizing the crossing takes less than an hour, which is critical when carrying out rescue and recovery operations in the centers of natural disasters.

It took a little over five minutes to organize the crossing of the Hongo River, after which the bridge was ready to move across it. The design is recognized as the lightest and fastest to install in the world. Dr. Iroh and his team intend to use similar structures to strengthen old bridges and organize a ferry while they are being renovated.
