摘要： PROBLEM TO BE SOLVED: To prevent the diffusion of vaporized mercury into the air and the inhalation of mercury vapor by operators. SOLUTION: In a method for preventing mercury vaporization, water is sprayed to mercury-polluted soil spreading in a polluted area 1 by using a hose 2 as shown in Fig. (a), water content of the mercury-polluted soil is increased and a water film is formed on the surface of granules of the mercury-polluted soil. Next, the mercury-polluted soil in the polluted area 1 where the water film is formed is dug/removed by using a backhoe and others as shown in Fig. (b). In this way by spraying water to the mercury-polluted soil spreading in the polluted area 1 by using the hose 2 to increase the water content and to form the water film on the surface of granules of the mercury-polluted soil, the mercury in the granules is out of contact with the air and the mercury remains in the granules to control its gasification. Finally, as shown in Fig. (c), earth 4 of good quality is added in the space 3 formed by digging. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To treat a volatile organic chlorine compound in situ even in the case where the inside of a contaminated soil is a cohesive ground and a concentration of the volatile organic chlorine compound is high.
SOLUTION: The in situ treatment apparatus 1 is almost constituted by an earth auger 4 as a mixing/stirring means in which a helical stirring blade 3 is mounted around a hollow shaft 2 and an excavation blade 11 is mounted to a tip end of the hollow shaft; and a power source 6 installed on a ground. The earth auger stirs and mixes the contaminated soil area 8 contaminated by a harmful volatile organic chlorine compound such as trichloroethylene and tetrachloroethylene spread in the ground 7. A conductive plate material 10 is buried in the contaminated soil area 8 so as to be arranged opposed to the earth auger 4. One terminal of the above power source 6 is electrically connected to the conductive plate material and the other terminal is electrically connected to the earth auger 4 constituted of a conductor.

摘要： PROBLEM TO BE SOLVED: To reduce a manufacturing cost without requiring a broad site near a tunnel opening. SOLUTION: A back filling grout material G is prepared by using water W, bentonite B, a hardening retarder Z, hydraulic cement C and a fine aggregate s. The grout material G is divided into bentonite slurry s and mortar M and they are respectively prepared at each different place. For the slurry S, a slurry- preparing apparatus 12 is installed neat the opening of the tunnel 10 to be constructed, and it is prepared here. The mortar M is prepared by using the cement C, the fine aggregate s and water at a ready mixing concrete factory. The mortar M is stored in a drum 18 capable of mixing and stirring and carried to the construction site of the tunnel 10. A specific amount of the hardening retarder Z and the slurry S stored in a tank 12d are added to the mortar M carried by a wagon 18. By rotating the drum 18 at a high speed, the mortar M and the slurry S are mixed and stirred to prepare the back filling grout material G.
