APPARATUS FOR DETECTING SOIL POLLUTION IN SUBSURFACE

摘要

According to the present invention, an underground soil contamination detection apparatus comprises: a perforated pipe buried in the surroundings of an underground facility where a leakage is predicted; a tube connected to the perforated pipe and is extended to the ground; a suction pump installed in the ground to suck underground gas by providing a negative pressure to the perforated pipe through the tube; and a gas analyzing device which analyzes the underground gas provided by the suction pump.
