Abstract

PURPOSE: To discharge permeated water to a sloped surface for preventing the disruption of the surface layer of the ground by laying a mat whose back layer is composed of a water-impermeable material in a slightly inclined and stepwise manner on the sloped surface when the sloped surface is formed by embedding the surface soil layer.
CONSTITUTION: In case where the foundation of the pier of a steel tower for power transmission line is constructed into a sloped form, a pit for the foundation of the pier is excavated in the slope and then the foundation is constructed. Afterwards, when the pit is embedded with soil, a mat 1 consisting of a nonwoven fabric mat body 1a having water-permeable pores and a water-impermeable mat 1b provided on the back of the mat body 1a is laid on the slope in stepwise manner from the lower part of the slope by turning its water-impermeable mat 1b downwards in such a way as to discharge permeated water to the outside of the slope, and then the sloped surface is back-filled with soil.
