At the site in the southern Shinshu area of Nagano Prefecture, the wall of the public road leading to a private residence has collapsed severely, necessitating restoration work. Due to the steep slope involved in the wall construction, this system was installed to ensure the safety of the workers. The construction period was approximately three months. Although there were some changes in strain values due to earthquakes, heavy rain, and snowfall, the work was completed safely without exceeding the pre-set values. This site has the system installed independently, but in some cases, safety can be further enhanced by using it in conjunction with devices such as "strain gauges." 【System Installed This Time】 ■ Monitoring Device ■ Rotating Light (with Buzzer) ■ Tripod ■ Setting and Monitoring Software ■ Strain Sensors 1m × 3 units *For more details, please refer to the PDF document or feel free to contact us.

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 *For more details, please refer to the PDF document or feel free to contact us.

At the construction site of the agricultural road improvement project next to the expressway in Yamanashi Prefecture, the slope has very soft soil, posing risks, and it was difficult to install the extensometer. This system was installed for the purpose of "monitoring the safety of workers involved with heavy machinery" because it can be set up quickly and easily. During work, the sound of heavy machinery makes it hard to hear alarms, so we placed the "alarm device" and "rotating light" at a high position, allowing all workers to easily detect danger at a glance. [Case Study] - Agricultural road improvement project site next to the expressway - The slope next to the construction site has steep and soft soil, making it prone to collapse - The rotating light is installed at a high position, making it visible to workers from a distance *For more details, please refer to the PDF document or feel free to contact us.

This is one of the large-scale landslide countermeasure construction sites that occurred due to the Iwate-Miyagi inland earthquake in June 2008. Currently, green space construction, embankment work, and road improvement work are being carried out. This system was installed to monitor the safety of workers involved with heavy machinery and other equipment. The "strain sensor" is characterized by its ease of installation. It is lightweight and compact, making it easy to transport, allowing a single worker to set it up. The site has soft soil, which allowed for smooth penetration. [Case Study] ■ Large-scale landslide countermeasure construction site ■ Installed to monitor the safety of workers involved with heavy machinery and other equipment *For more details, please refer to the PDF document or feel free to contact us.

At the "Highway Slope Restoration Work" site on Awaji Island, a slope deformation monitoring system has been installed for safety measures during construction. The installation was carried out by two workers, using a dedicated pre-boring machine for penetration, with four locations buried from the top. The alarm device was placed in the lower left so that it is visible from the road. Although the site conditions were poor, the installation was completed in about three hours. [Case Details] - The installation locations are a total of four, numbered No. 1 to 4. - The cable length is 100m, routed along the left side (using the top of the intrusion prevention fence). - The rotating light of the monitoring device was adjusted to a higher setting using a tripod. - The alert level is set to medium, and the alarm duration is set to 15 seconds. *For more details, please refer to the PDF document or feel free to contact us.
