Method for using unidirectional plastic geogrid in retaining wall In the category of plastic geogrid, uniaxially stretched plastic geogrid has the problem of high uniaxial tensile strength and weak tensile strength in the other direction. Therefore, such products are often used in places where high strength is required in one direction, such as retaining walls and high-fill slopes.

The number of roads for retaining walls is quite numerous. An example of the use of geotechnical materials in one type of vertical retaining wall is illustrated.
In recent years, with the increasing value of land, reducing the land occupation of the project has become a long-term requirement for the benefit of the country and the people. In the railway and highway construction projects, there are more and more upright-type retaining blocks.
From the perspective of external structure, the vertical retaining wall can be divided into a panel retaining wall and a non-panel retaining wall. The basic construction process of the panel retaining wall and the non-panel retaining wall is generally the same, mainly: leveling the roadbed, layering filling Soil, layered laying uniaxially stretched plastic geogrid, layered and crushed, after the design elevation is capped. The difference lies in: 1. The panel retaining wall generally reaches an upright position close to 90 degrees, and the non-panel retaining wall reaches an upright degree of approximately 60 degrees. 2. In the case of the fascia retaining wall, a steel bar that can be traversed through the connection is preset on the panel, which facilitates the direct link between the geogrid and the panel, so that the tensile strength of the geogrid can be fully exerted; in the non-panel project, The outer part is generally made of woven bag filled with soil. The unidirectionally stretched plastic geogrid is tightened by the reverse wrapping of the woven bag, and each layer of woven bag is slightly staggered and continuously raised to form a stable slope structure. If some grass seeds suitable for greening are added to the woven bag, the wall will become a beautiful green belt after being made.
Construction of one-way stretched plastic geogrid retaining wall Note: Unidirectionally stretched plastic geogrid is divided into polypropylene plastic geogrid and polyethylene plastic geogrid according to the material. In the use of soil walls, plastic geogrids of both materials can be used, but polystyrene plastic geogrids have better creep strength than polypropylene plastic geogrids at the same tensile strength. If a polypropylene plastic geogrid is used, a higher tensile strength should be used. 2. The layered rolling must reach the specified degree of compaction. Large machines must not be used within 1.5 meters of the outside of the retaining wall. 3. If steel-plastic geogrid is used, the product with high strength of joint peeling force should be selected, preferably the steel-plastic composite geogrid with convex point.
