Embodiment Construction

[0035] The present invention is described in detail below in conjunction with accompanying drawing;

[0036] see Figure 1-Figure 5 , an embodiment of a geogrid-reinforced wall of the present invention, comprising a surface system and a geogrid-reinforced soil body, the geogrid-reinforced soil body is composed of 12 layers of geogrid laid horizontally and a backfill filler layer 11 are alternately pressed together. The other side of the geogrid-reinforced soil opposite to the surface system leans against the hard slope surface 10, and the hard slope surface 10 is provided with a number of anchor drills that are substantially perpendicular to the surface of the hard slope surface 10. hole 17, the hole diameter of the bolt hole 17 is 50-100mm, and the distance between the adjacent bolts 9 is 60-250cm. The anchor rod 9 is inserted into the anchor rod borehole 17 and fixed by cement mortar 16, and the geogrid 12 and the anchor rod 9 are connected together through a connecting me...

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...
