Applications/Examples of results

Investigations targeting "soft rock" ground, which has intermediate properties between soil and rock, have become more common in construction projects across various regions. In projects involving such ground, there are numerous issues unique to soft rock that cannot be addressed using knowledge and methods derived from soil or conventional hard rock formations. Therefore, there is a need for testing instruments to appropriately evaluate the properties of soft rock. This device is an optimal testing instrument for managing tests at construction sites involving such soft rock ground.
