The invention discloses an anchor rod reinforced composite retaining wall and a construction method. The anchor rod reinforced composite retaining wall comprises retaining wall panels, a retaining wall cap stone, a retaining wall foundation, a structural grille and geogrid interlayer filled earth behind the wall, and further comprises inverted filters arranged and abutted on the back surface of the retaining wall panels, and inverted wrapped layers composed of geogrid inclusion bodies, and a matched procession type limit anchor rod. The retaining wall panel is of a reinforced concrete composite panel, rib columns to increase the overall strength of a wall surface are arranged on the surface, penetrating retaining wall planes and anchor rod leading holes to limit angles of the anchor rod are arranged on the upper part of the rib columns, connection parts of reinforced materials are arranged on the back of the wall at intervals, geogrids behind the wall are divided into main structural grilles and sub-structure grilles, the main structure grilles penetrating through the inverted filters are directly connected with the back of the wall through the connection parts of the back of the wall, the sub-structure grilles between every two adjacent main reinforced layers is laid in an inverted wrapped mode, and the effect of reinforcing soil bodies is achieved by the inflection of the materials with a good inclusion water permeability.
Description
technical field [0001] The invention relates to an anchor bolt reinforced composite retaining wall and a construction method thereof, which belong to the technical fields of roads, railways, and rock and soil. Background technique [0002] Since the 21st century, reinforced soil technology has been widely used in the field of geotechnical engineering. With the continuous development of construction level, the application field of this new technology has been expanding. In particular, reinforced earth retaining walls are widely used in roads, railways, bridges, municipal and other fields due to their small footprint, low price, convenient construction, beautiful appearance and good seismic performance. [0003] The general reinforced soil retaining wall is composed of three parts: the face plate, the reinforcement material and the filling between the reinforcement materials. The lateral pressure generated by the self-weight of the fill soil and other external loads acts on th...
