Title: Tadao Sugimoto: Innovative Solutions for Underground Structures
Introduction
Tadao Sugimoto, a distinguished inventor based in Nagoya, Japan, has made significant contributions to the field of civil engineering through his innovative patents. With a total of 2 patents to his name, Sugimoto has developed methods that enhance the safety and reliability of underground structures in conditions prone to liquefaction.
Latest Patents
Sugimoto's latest patents address the challenges posed by high water permeability in soils susceptible to liquefaction. His first patent outlines a method of protecting underground structures by forming a conglomerate layer horizontally on a base ground which easily liquefies. A bottom plate is constructed on this conglomerate layer, and several drainpipes extend from the layer through the bottom plate to effectively drain excessive pore water, ensuring stability.
The second patented method focuses on protecting structures built on such ground. It involves creating a conglomerate layer in soil with high water permeability, where an underground base of the structure is constructed atop this layer. Similar to his first invention, drainpipes are extended from the conglomerate layer through the base, communicating with the surface to manage pore water pressure and enhance the structure's integrity during seismic events.
Career Highlights
