Geogrid reinforced wall and construction method thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the field of geotechnical technology, and in particular relates to a geogrid-reinforced wall and a construction method thereof. Background technique [0002] In the current construction of highways, railways, mines, foundation pits, municipal projects, etc., different retaining structures are used due to different geological conditions. The retaining structures used for excavating slopes in engineering can be divided into two categories: rigid retaining structures and flexible retaining structures. [0003] Rigid retaining structures refer to masonry structures (gravity retaining walls, anti-slide piles, flake walls, etc.), supplemented by other necessary comprehensive treatment schemes. For rigid retaining structures, low retaining structures such as masonry rubble and gravity retaining walls are bulky and require more masonry (generally less than 8m in height); reinforced concrete cantilever and buttress retaining walls (gen...
