PURPOSE:To completely stop the flow of water by a method in which a water- impermeable sheet is inserted into an excavated trench filled with mud water and doubled with a water-impermeable sheet with a locking bag to seal up the trench and solidify it. CONSTITUTION:A trench 9 for one cycle is excavated and filled with mud water 10. A water-impermeable sheet 1 is inserted into the trench 9 filled with mud water, and the female coupler 3 of a water-impermeable sheet 6 with a locking bag 7 is matched with the upside of a male coupler 2 of the sheet 1, and the sheet 6 is inserted. A grout 8 is injected into the bag 7 to seal up the trench 9 and a grout 11 is injected into the space A partitioned by the bag 7 and hardened. The construction efficiency can thus be raised without the use of the conventional steel partition plate and locking pipe.
