摘要： PROBLEM TO BE SOLVED: To provide a remedial method for a soil atmosphere utilizing a tank which has been established, said method cleaning a large amount of soil quickly and a soil washing equipment. SOLUTION: The inner part of a tank 1 that has been established is divided into a soil washing tank 10, a water/pollutant separation tank 20, a cleaning agent injection water tank 30 and a muddy water treatment tank 40. The pollutant 4 in a contaminated soil 2 is transferred to a washing water 5 by throwing/stirring a fixed amount of contaminated soil 2 around the tank 1 and the washing water 5 of the injection water tank 30 to a washing tank 10. A pollutant-containing water 8 is caused to flow into the separation tank 20 if the soil is precipitated, and a pollutant-containing water 8 is caused to flow into the separation tank 20 after the muddy water 7 comprising the contaminated soil 2 and the washing water 5 is separated into mud 9 and the pollutant-containing water 8 by transferring the muddy water 7 to a treatment tank 40, if the soil is not precipitated. The pollutant-containing water 8 is separated into the pollutant 4 and the water 6 at the separation tank 20, and then the mud 9, the pollutant 4 and the water 6 are discharged outside the tank 1 to returned a precipitation soil 3 of the washing tank 10 to the tank surrounding. A cycle from charging to returning for the required surrounding contaminated soil 2 is repeated.

摘要： PROBLEM TO BE SOLVED: To provide an air bubble entraining reclamation method and its device, which can easily cope with reclamation treatment ranging from small quantity to large quantity at a low cost. SOLUTION: Reclamation modules (M) each comprising an oil separating tank 11 into which contaminated soil (D) is fed and an oxidizing agent is poured for separating oil from the contaminated soil by air bubble entrainment, and a neutralizing and washing tank 21 for diluting and washing the alkaline components of the soil treated in the oil separating tank 11 are parallelly installed by the prescribed number of sets required for reclaiming contaminated soil. A central treatment device (C) is installed, which is provided with chemical tanks 13, 23 for storing chemicals for cleaning the oil separating tank 11 and the neutralizing and washing tank 21, and treatment devices 12, 22 for treating waste oil (P), wastewater (L), and waste liquid generated by reclamation treatment.

摘要： PROBLEM TO BE SOLVED: To provide an excavation method of unneeded buried items for not leaving a wall in the ground after removing the unneeded buried items.
SOLUTION: At the time of forming an excavation hole H in an excavation object area, a frozen pipe 1 is embedded around the excavation hole H and a frozen ground wall R is formed. The excavation of the excavation hole H is performed while preventing the inflow of groundwater by the frozen ground wall R. By attaching a liner plate 2 to the inner side face of the excavation hole H, the hole wall of the excavation hole H is protected. The excavation of the excavation hole H is ended, contaminated soil is removed, the excavation hole H is filled back with the soil of excellent quality, and then the frozen ground wall R is thawed.
