A restored and reinforced scarp and its structure and restoring and reinforcing structure for a scarp is provided. The scarp comprises of the following: the scarp surface under restoration is cleaned, and a pit (an excavation) is created. The bottom of the pit is filled with mineral soil and is compacted as a foundation of a retaining wall. A protective filter made from draining mineral soil is installed on the foothill of the scarp, where the protective filter is surrounded by draining geotextile. The geogrid is placed on the surface of the regressed scarp and then anchored to the soil of the scarp by tensile ropes. A rigid support, such as a crib (grillage), is created on the protective filter and batter piles are driven under the rigid support. Then the retaining wall is constructed, consisting of layers of compacted soil that are surrounded by draining geotextile. The retaining wall is covered by erosion control mats, anchored to the draining geotextile of the soil layers of the retaining wall. Protrusion in the scarp is covered with large granite boulders or concrete elements. |
