IMPERVIOUS METHOD FOR SLOPE FACE

摘要

PROBLEM TO BE SOLVED: To improve the working efficiency of the impervious works and provide an impervious method for a slope face of which the impervious sheet is not broken by stones in the stones and sands fed afterwards as conventional cases by integrating the impervious sheet with sand bags and simultaneously laying them together on the slope face. SOLUTION: Sand bag mats 2 are fixed onto the upper face of an impervious sheet 1 and the impervious sheet is fixed by a string or the like onto a base for stretching the sheet coinsided with the shape of the slope face and the whole body is suspended down onto a specified place of the slope face and further, slurry-state sand is filled in the sand bag mat 2.
