Abstract: PROBLEM TO BE SOLVED: To provide a method for freezing and removing polluted soil, for making block-shaped frozen soil by utilizing a freezing technique and sealing the volatilization of a harmful substance or the malodor of waste with ice to more reduce an environmental risk than before while enhancing the removal/feed-out efficiency of polluted soil.
SOLUTION: This method for freezing and removing polluted soil has a cooling pipe arranging process for arranging cooling pipes in polluted soil, in which a pollutant is present, so as to make the distances between the center parts of the cooling pipes equal, a cooling process for supplying a freezing medium to the cooling pipes to form discontinuous frozen soil comprising the surface part of non-frozen soil and the remainder of frozen soil around the cooling pipes, and a frozen soil removing process for taking out the frozen part of discontinuous frozen soil to the surface of the ground.

Abstract: PROBLEM TO BE SOLVED: To efficiently polish both of a polishing surface with small recesses and a flat polishing surface by a hand-held nonwoven polishing sheet. SOLUTION: The nonwoven polishing sheet comprises: fibers sterically and undirectionally collected and joined at their intersection points to have 3-20 mm thicknesses; and abrasive grains attached in spaces among the fibers from the surface toward the inside. The sheet is flexible and cut to such a size as to be hand-held for polishing a polishing object. Further, the sheet is formed with a plurality of notched lines 2 arranged linearly at predetermined pitches in such a manner that the notched lines 2 pass in the surface or through both the surfaces. The sheet is folded back with the notched lines 2 as folding lines, thereby to polish the object with the cutting surfaces 3 exposed along the folding lines. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To provide an earth retaining cut-off structure and an earth retaining cut-off method capable of very safely carrying out work of a widening section by enhancing freezing force (shearing force) and freezing separation resistance force in an abutting section of an earth retaining cut-off wall of frozen soil and tunnel lining materials to prevent the collapse of the earth retaining cut-off wall and the deformation and displacement of the lining materials.
SOLUTION: Shield holes 1 and 1 are bored in parallel with each other. The earth retaining cut-off wall 2 of frozen soil is formed between the shield holes 1 and 1. Both ends 2a and 2a of the earth retaining cut-off wall 2 are respectively abutted on skin plates 3a of steel shelled segments 3 installed as the lining materials of the shield holes 1 and 1. Dowels 4 are projected to the abutting section of both ends 2a and 2a of the earth retaining cut-off wall 2 and the skin plates 3a of the steel shelled segments 3.
