Title: Hachiro Kubota: Innovator in Demolition Technology
Introduction
Hachiro Kubota is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of demolition technology, holding a total of 3 patents. His innovative methods focus on the destruction of brittle materials through unique hydration expansion techniques.
Latest Patents
Kubota's latest patents include a method of destroying a brittle body by hydration expansion. This method involves molding around an elastic tube or a plastic wire, which defines a charging hole. After removing the tube or fusing the heat-fusible member, an expandable splitting agent is charged into the hole and subjected to hydration expansion to destroy the brittle body. Another form of this invention includes a water-impermeable film that encloses the expandable splitting agent, which is buried in the brittle body and later activated to achieve demolition.
Additionally, he has developed an expansive demolition agent prepared by crushing clinker to create a powdered agent capable of hydrating and expanding within a drilled hole in brittle material. This agent is designed to effectively demolish the material while maintaining specific particle size requirements.
