Title:
CONSTRUCTION METHOD FOR IMPERVIOUS WALL
Document Type and Number:
Japanese Patent JP3240394
Kind Code:
B2
Abstract:
PURPOSE: To increase imperviousness and facilitate the connection work of impervious sheets by making the impervious sheets in double construction and connecting them in a large shaft in which grooves are connected.
CONSTITUTION: Multiple grooves 1 are excavated in the ground longitudinally at specified intervals. Also impervious sheets 2 folded into two parts are erected in the grooves 1 with their folded parts faced downward. Solidifying material 3 is filled between the impervious sheets 2 to construct impervious walls 31. In this case, the impervious sheets 2 are fitted closely into the wall sides of the grooves 1. Next, a sunk buried holes 4 are excavate at the ends of the impervious walls 31, and shaft can bodies 5 are sunk installed in them. Solidifying materials 6 are filled into the surrounding areas of the shaft can bodies 5. The gates 51 of the shaft can bodies 5 are opened, and the impervious sheets 2 are pulled out from the impervious walls 31. The impervious sheets 2 of the adjacent impervious walls 31 are connected. Finally solidifying materials are filled into the shaft can bodies 5 to connect the impervious walls 31 and 31.
