PURPOSE: To eliminate degradation of stabilizing liquid facilitate in use building-in and connecting work of a water cut-off sheet, improve wokability and water cut-off ability, and utilize a part of a water cut-off wall as a pumping well. ;CONSTITUTION: A drilled groove 6 is formed in the ground while using wall stabilizing liquid 5, and a bag body 1 which is provided with the length actually corresponding to the depth of the groove, provided with respective male and female connecting metal fittings 2a, 2b on both side parts, and made of a liquid impermeable sheet, is built in against the drilled groove 6 in the contracted condition. Thereafter, filler is injected into the bag body 1, and a continuous cut-off wall W wrapped by liquid impermeable sheet is built in the drilled groove 6. At connecting parts of the water cut-off walls W, a vertical hole space P is formed in the depth direction by means of the connecting metal fittings 2a, 2b, and the vertical hole space P is utilized as a pumping well.;COPYRIGHT: (C)1994,JPO&Japio
