Embodiment Construction

[0043] The present invention is described in detail below in conjunction with the accompanying drawings:

[0044] see Figure 1-Figure 4 , an embodiment of a concrete panel reinforced retaining wall of the present invention includes a surface layer and a geogrid reinforced wall body, the surface layer is an integral cast-in-place concrete panel 1, and the bottom of the integral cast-in-place concrete panel 1 A concrete strip foundation 8 is provided, and the geogrid reinforced wall is a back-packed geogrid reinforced wall, and the back-packed geogrid reinforced wall and the integral cast-in-place concrete panel are 1 are connected together by steel mesh 2 and pre-embedded anchoring steel 3.

[0045] The above-mentioned return-packed geogrid reinforced wall is formed by alternately pressing 4 layers of geogrid and filler layers. The 4th floor of the geogrid adopts one-way geogrid, and the upper and lower one-way geogrids 4 are connected by connecting rods 9.

Abstract

The invention provides a concrete panel reinforced retaining wall and a construction method of the concrete panel reinforced retaining wall. The concrete panel reinforced retaining wall comprises a surface layer and a geogrid reinforced wall body, and is characterized in that the surface layer is an integrated cast-in-place concrete panel, a concrete strip foundation is arranged at the bottom of the cast-in-place concrete panel, the geogrid reinforced wall body is a wrapped-face geogrid reinforced wall body, and the wrapped-face geogrid reinforced wall body and the integrated cast-in-place concrete panel are connected together through a reinforcing mesh and embedded anchor bars. The construction method includes the steps of foundation earth excavation, construction of the strip foundation on the base of a slope, construction of the reinforced retaining wall and construction of the cast-in-place concrete panel. The concrete panel reinforced retaining wall integrates advantages of a wrapped-face reinforced retaining wall and a panel-type reinforced retaining wall, and is high in integral rigidity, not prone to horizontal deformation and suitable for the conditions that the retaining wall is large in height and gradient and a slope surface faces water. The concrete panel reinforced retaining wall has the advantages of being high in stability, high in construction speed, good in anti-shake performance, wide in application range and the like.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, in particular to a concrete panel reinforcement [0002] Retaining wall and construction method thereof. Background technique [0003] For a long time, the traditional geogrid reinforced retaining wall generally adopts two forms of wrapping reinforced retaining wall (greening) and modular reinforced retaining wall (non-greening). [0004] Wrap-around reinforced retaining wall (greening) refers to a reinforced retaining wall formed by wrapping slope fill with geogrid. This form of reinforced retaining wall connects the upper and lower geogrids together with connecting rods. , so that the entire reinforced retaining wall forms a whole, with good integrity. However, the panel stiffness of this type of retaining wall is approximately zero, and its design range is limited by the slope (generally, the slope should not be greater than 70°). [0005] Modular reinforced retaining wall ...
