Pneumatic Caissons
We, as the pioneer of the pneumatic caisson method in Japan, have our track records for more than 70 years in the field and constantly developed our technology responding to the contemporary requirements. Nowadays the pneumatic caisson technology is required to meet very deep and large scale underground development projects. We have steadily developed our technology to satisfy the current time needs.
Our pneumatic caisson technology features, among others, mechanized and/or unmanned excavation operation, safety control of pressurized air, noise and environmental control and so forth.
