Four years have passed since the Great East Japan Earthquake, which killed thousands of people and damaged many properties. Japanese, as well as people around the world, vividly remember the deadly natural disaster, with some of the destroyed areas in the Tohoku region still unrestored.
While municipalities in Japan are working on projects to reduce disaster risks in preparation for possible huge earthquakes and tsunami, the "Implant Structure," which Giken Ltd. promotes and practices, is garnering attention.
An Implant Structure is a resilient infrastructure in which preformed structural components, each of which is very sturdy, are pressed deep into the ground on site by various Silent Pilers. The structure is effectively integrated with the earth, and carries horizontal and vertical loads, using the "size of section" and "depth of penetration." As a result, it is highly resistant to ground displacement caused by the motion of earthquakes, tsunami and other external forces, serving as a resilient disaster-prevention infrastructure.
