Under-road cavity exploration services

Overview

Currently, it is said that more than 3,000 incidents of road cave-ins occur annually in Japan. Many such incidents are caused by the deterioration of underground pipes, such as sewage pipes and rainwater pipes. This is because water leaks into the ground from broken pipes or loose joints, which erodes the surrounding ground and creates cavities that cause cave-ins. If a road caves in, there is a danger of serious accidents involving falling people and vehicles. Furthermore, firefighting and rescue activities will be greatly hindered if roads become unusable in an emergency, such as an accident or disaster.
By using exploration vehicles equipped with ground penetrating radar for detecting cavities under roads, OYO Corporation provides a service to prevent cave-ins by using non-destructive methods to detect cavities under roads.

Features

Scans cavities inside roads at intervals of 2.5 cm even at 80km / h

Underground radar is a technology that can identify dangerous voids and buried pipes by irradiating electromagnetic waves from above roads. Our voids exploration vehicles can investigate the road at a high density of only 2.5cm intervals even when driving at speeds of 80 km per hour.
