[ZEROSAI Case Study] Concrete Structure Repair Work

Repair work under the expressway, technical proposal, creativity and ingenuity, concrete placement quality control.

【Operating Environment】 N sensors are installed on-site to observe rain, wind, temperature, and humidity in real-time. Additionally, since there is no power supply on-site, operations are conducted using solar power equipment. 【Purpose of Introduction】 - Since work is being carried out within scaffolding, it is necessary to manage the temperature and humidity inside the scaffolding rather than the outside air temperature. Therefore, only a hygrometer is installed inside the scaffolding to manage the quality of the concrete. - Rapid information sharing with workers is facilitated through email notifications. - Observation data is utilized as supporting documentation. 【Operating Method】 - A hygrometer with built-in communication functionality is installed in the designated slab area to collect real-time observation data, thereby managing the quality of the concrete within the scaffolding. - Project management is conducted by utilizing forecast data from long-term, short-term, and ultra-short-term perspectives. - In the event of exceeding the standard values of weather forecasts or N sensor observation values, email notifications are sent to workers to alert them, enabling prompt action and preemptive measures. - Observation data can be output as PDF files for daily and monthly reports, which can be directly used as supporting documentation.
