Self-anchored toothed grid reinforced retaining wall structure and reinforcing method thereof

Abstract

The invention discloses a self-anchored toothed grid reinforced retaining wall structure and a reinforcing method thereof. A plurality of layers of toothed grating reinforcement units are horizontallyarranged, each toothed grating reinforcement unit comprises an L-shaped reinforcing mesh and toothed gratings, a horizontal reinforcing mesh of the L-shaped reinforcing mesh extends into a soil filling layer, a vertical reinforcing mesh of the L-shaped reinforcing mesh is tightly attached to the side slope, the upper end of the vertical reinforcing mesh is connected with one end of the horizontally-arranged toothed grating through fasteners, and the other end of the toothed grating is fixed to the soil filling layer through short anchor piles in a self-anchored mode; the toothed grating is provided with a plurality of toothed ribs arranged in parallel, the toothed ribs are parallel to the side slope, and the section shapes of the toothed ribs are in a smooth transition shape with a narrowupper part and a wide lower part. The self-anchored toothed grid reinforced retaining wall structure is good in structural integrity, high in slope stability, low in manufacturing cost, wide in application range and convenient to construct, and materials are saved.

Description

technical field [0001] The invention belongs to the technical field of building structures, and relates to a self-anchored toothed grid-reinforced retaining wall structure and a reinforcement method thereof, which can be applied to roadbed filling. Background technique [0002] Reinforced earth retaining walls are widely used in the field of road engineering. The basic principle is to resist part of the sliding force through the friction between the filler and the reinforcement, so as to maintain the stability of the roadbed. At present, the commonly used reinforced retaining wall is composed of wall panels, reinforcement materials and filling soil, and can also be supplemented by other support forms such as anchor rods. [0003] Existing reinforced retaining walls usually have the following deficiencies: [0004] 1. The traditional geogrid usually can only rely on the interface friction between it and the filling to resist the sliding force, but its working mechanism deter...

AI Technical Summary

Problems solved by technology

[0004] 1. The traditional geogrid usually can only rely on the interface friction between it and the filling to resist the sliding force, but its working mechanism determines that the resistance it can provide is very limited, and it may be necessary to add additional anti-skid facilities

[0005] 2. The connection between the common L-shaped reinforced panel and the reinforcement is generally set at the rear edge of the bottom of the panel. This connection method is vulnerable to hidden damage caused by the layered compaction of the filling, resulting in fracture

[0006] 3. The surface of the retaining wall after completion is usually covered by cement panels, which not only affects the appearance, but also has not fully exploited its ecological value
