The sensor measures movement in the soil! It helps determine whether something is "moving" or "stopped"!
In the mountain conservation construction site in the Tohoku region in 2011, a landslide occurred due to the earthquake and heavy rain from two years prior, causing the dam to collapse.
Although repair work on the dam was carried out, the soil at the site was very soft and posed dangers, making it difficult to install the displacement gauges.
This system was installed with the purpose of monitoring the safety of workers involved with heavy machinery.
In addition to "two rotating lights" and "alarms," a "large siren" was also used, making it easier for workers, who might have difficulty hearing the alarms due to the noise of the machinery, to detect danger. The strain sensors are reinstalled and used as the construction site moves.
[Case Study]
■ Mountain conservation construction site in the Tohoku region
■ Soft and easily collapsible soil
■ Monitoring devices (2 units) and a large siren (1 unit) were installed
■ Sensors were also buried upstream, with extended cables connected to the monitoring devices
