This is the Japan’s largest underpinning for constructing a new underground expressway, directly under the existing subway structure in service. The displacement controlling value of the subway structure was so small that the conventional technology cannot handle the situation. However, the technology development of the "Automatic control system for underpinning" and the "Underpinning construction equipment" overcome the difficulties and enabled the expressway structure to be safely completed The introduction of these newly developed technologies resulted in a drastic improvement in safety of under pinning work, and they are expected to be applied to similar future projects.
