The "Monitoring Case Studies of the Impact on Railway Tracks" introduces examples of real-time monitoring of ground displacement at the surface and subsurface using the Observation King to ensure safe railway operations. The measuring instruments connected to the Observation King included a total station capable of measuring surface displacement and a "designed-type inclinometer" that can measure depth displacement both at the surface and deep underground. In areas where secondary disasters on slopes are a concern, real-time monitoring is required, making remote monitoring with the "designed-type inclinometer" effective and also cost-effective from the perspective of automatic observation. 【Features】 ■ Monitoring of subsurface using designed-type inclinometers ■ Proximity construction with railway tracks *For more details, please refer to the PDF document or feel free to contact us.

The "Monitoring Cases of Water Level and Water Quality" introduces construction examples conducted for safe tunnel construction in mountainous areas. We carried out groundwater level lowering work using the "Deep Well Method," and monitored the water level, pumping volume, and the water quality of the discharged groundwater. We also monitored the water levels of existing observation wells in the surrounding area. To eliminate cumbersome wiring work, we used "specific low-power wireless," achieving a reduction in work processes and costs. [Features] ■ Monitoring of groundwater levels and water quality ■ Reduction of work processes and costs through the use of wireless equipment *For more details, please refer to the PDF materials or feel free to contact us.

The case study titled "Monitoring Behavior of Steep Slope" is based on the Kumamoto earthquake that occurred in April 2016. To ensure a prompt emergency response to the rockfall on the national highway and to fully reopen the road, monitoring was conducted while implementing one-lane alternating traffic. The monitoring involved the installation of a "total station" on the opposite side of the collapsed slope, along with surveillance cameras positioned to provide a comprehensive view of the entire collapsed slope for real-time automatic monitoring. In steep slope areas, monitoring using a total station proved effective, allowing not only measurement data but also image verification, which enabled a cross-check to understand the behavior of the collapsed surface. [Features] ■ Response to sediment disasters caused by the Kumamoto earthquake ■ Monitoring of steep slopes using a total station *For more details, please refer to the PDF document or feel free to contact us.

The cut slope method is designed based on the hardness and weathering degree of the ground, geological structure, groundwater conditions, etc., identified during preliminary investigations, as well as the excavation slope and countermeasures. However, due to partial differences in weathering and geological structure that cannot be fully grasped during the survey, slopes often deform and can ultimately lead to collapse. Therefore, it is necessary to quickly detect any deformation at an early stage during cut slope construction and take emergency measures. Chuo Development Co., Ltd. supports safe and economical safety management through comprehensive construction monitoring services, including the arrangement and measurement of flexible measuring instruments and remote automatic monitoring.

When a disaster such as a landslide occurs on a slope along the road, even if the debris blocking the road is removed, the slope remains in a dangerous state with exposed earth, making it prone to secondary disasters until restoration work is completed. On the other hand, since vehicle passage is required as it serves as a regional artery, the temporary passage period until full restoration necessitates very high-level management. Chuo Development Co., Ltd. supports road management during disasters through comprehensive slope monitoring services, including monitoring with measuring instruments, real-time web distribution of data, alert email notifications, 24-hour surveillance, and slope inspections by technicians.

Natural and artificial slopes gradually change due to factors such as loosening and sliding. "Kantarou" is an inclination sensor developed with the aim of capturing these changes. It can also be used for monitoring changes in objects other than slopes, such as unstable rock masses and structures. The measurements taken by "Kantarou" are often aimed at ensuring the safety of preservation targets located below the slope during construction work or in preparation for secondary disasters. It is registered as a NETIS technology. 【Features】 ■ Captures inclination changes of slopes, etc. ■ Usable for monitoring changes in objects other than slopes, such as unstable rock masses and structures ■ Ensures the safety of preservation targets located below the slope during construction work or in preparation for secondary disasters *For more details, please request materials or view the PDF data from the download.

Currently, surveillance cameras are being installed along major rivers, reflecting an increased awareness of disaster prevention in river management. Additionally, in terms of information disclosure, there is a demand for easy-to-understand display methods for water level markers for residents. The high-brightness phosphorescent water level marker is a groundbreaking device that, unlike the conventional reflective type, absorbs ultraviolet light to store energy and emits light, making the scale of the water level marker visible without the need for auxiliary light sources in unexpected situations, thereby ensuring a minimum safety line.
