Information on disaster prevention, mitigation, and disaster response technologies for natural disasters.

basic information

**Features** ○ Geological survey for the construction of the Unzen Fugen-dake sediment control dam. Unzen Fugen-dake has caused significant damage due to pyroclastic flows and debris flows. We conducted a thorough investigation in the planned sediment control dam area of the waterless river, which is a restricted zone, ensuring both safety and technical aspects. ○ Sand ejection situation due to the Great Hanshin Earthquake in January 1995. Sand ejection due to ground liquefaction was observed in various locations, and our company conducted various surveys and analyses related to the recovery from the earthquake disaster. ○ Slope stabilization measures using free frames. This is the construction status of the road slopes in Kashiwabara Town, Hyogo Prefecture, for which our company carried out the design. ○ Gas pipeline network warning system during metropolitan area earthquakes. In earthquake disaster prevention, it is crucial to minimize damage to lifelines such as gas pipelines. This system detects a major earthquake instantly, shuts off gas supply, and minimizes secondary disasters such as fires, while also facilitating recovery. Our company developed liquefaction sensors for detection and contributed to the overall construction of the system. ● For more details, please contact us.
