These case studies highlight how GeoSitter's monitoring instruments, data management software and hydraulic jacks for pile load test excel in a number of projects.
In order to achieve unmanned and real-time automated monitoring of dams, Geositt introduces a reservoir dam monitoring system. The reservoir dam safety monitoring system collects data on dam settlement, inclination, water pressure, and dam shape characteristics. By acquiring, organizing, and analyzing various information, the system conducts a safety assessment of the dam, verifies the accuracy of calculation parameters for controlling the safe operation of the dam, evaluates the practicality of calculation methods, and provides feedback on the correctness of construction methods. This aids management personnel in making accurate and rapid disaster warnings and forecasts, ensuring the safety of people's lives and property.
