Technique for Promotion of SMH Plan (Bridge Inspection Support System)

Input support such as inspection position using position recognition technology

We have developed a system that automatically acquires structure information etc. from the position information of the inspector using GPS and multifunctional sensor and reflects the inspection data entered at inspection at the inspection management system. Utilizing this system enables efficient on-site inspection work.

Variational evaluation support using large-capacity image analysis technology

We developed a system that supports similar deformation data by presenting similar deformation data in the past to deformed data acquired by inspection.
In addition, by automatically accumulating judgment information of experts, it will be possible to visualize judgment know-how and to efficiently train judges.

Adhesion method of carbon fiber sheet

Although corrosion of steel bridges is often caused in part, general repair using steel plates requires dedicated equipment and specialized technicians even for local repairs, and repair costs are extremely high and expensive. Therefore, we developed a steel girder repairing method using carbon fiber sheet which can repair cheaply even with localized corrosion. This makes it possible to efficiently repair steel girders with simple equipment.
