| Abstract |
Soil and sand of various kinds occurred in earth excavation and land development stage of the construction project can be utilized in various ways according to its kind. The soil and sand occurred in such construction work is classified as waste in the current waste management law; however, it is used in many ways in various kinds of construction work in reality since it contains less foreign substance and the specific physical characteristics possible to use as banking material is secured. However, considerable amount of soil and sand polluted with oil due to oil leakage and intentional discharge of waste oil among the soil and sand from construction work is occurringfrom oil storage facilities or other facilities installed underground. If such polluted soil and sand is used as banking material, heavy metal and etc. may be worried about flowing out and affecting the land environment for the long period of time. Therefore, it is restricted in the country with Waste Management Law. Several methods possible to use such polluted soil and sand have been suggested and the statistic of the Ministry of Environment says that enormousquantity of polluted soil and sand occurs amounting to 27% of the total quantity of soil and sand occurrence in reality. It is considered greatly contributable to the conservation of national land environment if it is reused, therefore, the method for treatment of oil polluted soil and sand is currently required. Accordingly, the purpose of this research is to reuse waste soil and sand as refilling material for pipeline construction work by suggesting the method for reusing oil polluted waste soil and sand in order to reutilize the waste soil and sand polluted from oil after examining and analyzing the purification characteristics according to the rate of addition of washing solution and the time for washing. |
