Geogrid reinforced wall and construction method thereof

The invention provides a geogrid reinforced wall and a construction method thereof. The geogrid reinforced wall comprises a surface layer system and a geogrid reinforced soil body and is characterized in that the other side surface of the geogrid reinforced soil body, which is opposite to the surface layer system, is leaned on a hard slope surface; the hard slope surface is provided with an anchor rod drilled hole; an anchor rod is inserted and fixed in the anchor rod drilled hole; and the geogrid is connected together with the anchor rod by a connecting component. The construction method comprises the following steps: (1) digging of foundation earthwork; (2) construction of a strip foundation; (3) construction of an anchor rod anchoring structure; (4) construction of the connecting component between the geogrid and the anchor rod; and (5) construction of a geogrid reinforcing structure. The invention solves the problem of limitation on space of a reinforcing field; the geogrid reinforced wall adopting a flexible retaining structure can be constructed in regions which are narrow in field, are limited in space and contain rocks and native-state hard soil; the geogrid reinforced wall and the construction method thereof have high construction efficiency and are low in cost; and the wall has a firm and stable structure.
