PURPOSE : A contaminated ground purifying system and a method for the same are provided to easily extract contaminants from a contaminated space under the ground.CONSTITUTION : A contaminated ground purifying system(10) includes an underground manhole, an injection unit(100), an extraction unit(200), an injection line, and an extraction line. The injection unit includes at least one horizontal injection well(110) and injection pump(120). The extraction unit includes at least one horizontal extraction well and vacuum pump(230). The horizontal injection well is arranged in an empty space of the underground manhole, and is horizontally buried under the ground. The horizontal injection well includes a first horizontal injection well with a first perforated case and a first spraying unit. Pores are formed on one outer circumference of the first perforated case. The first spraying unit is installed in the first perforated case and sprays purified air into a contaminated space under the ground. The horizontal extraction well is arranged in the empty space of the underground manhole and horizontally buried under the ground. The horizontal extraction well includes a first extraction well with a first perforated case and a first extraction unit. Both perforated cases are horizontally buried toward the underground while probing underground water. The injection line and the extraction line are arranged in the empty space of the underground manhole.COPYRIGHT KIPO 2013
