PURPOSE: A space continuity non-constructive ground investigating system is provided to efficiently and promptly perform a ground investigation work by easily moving an oscillating apparatus and an isolating apparatus, and improve the reliability of data by sensing elastic acoustic waves at several places. CONSTITUTION: A space continuity non-constructive ground investigating system includes a tripod(20) setting a hit position of the ground, a hitting element(42) installed at the tripod and hitting the ground for generating elastic acoustic waves, a winding machine(50) winding the hitting element, a sensor mounted at a movable truck for sensing the elastic acoustic waves generated by a hit of the hitting element, a pressing element contacting the sensor to the ground with a predetermined force, and a guide element guiding the lifting of the sensor.
