Bidirectional plastic geogrid is a geosynthetic material made of high polymer materials, mainly processed through extrusion, planking, punching, and longitudinal and transverse stretching processes. The following is a detailed introduction to the bidirectional plastic geogrid:

1、 Materials and Manufacturing

Material: The bidirectional plastic geogrid mainly uses synthetic resins such as polypropylene (PP), polyvinyl chloride (PVC), or polyethylene (PE) as raw materials.

Manufacturing process: These raw materials are first extruded into sheets, then punched, and finally subjected to longitudinal and transverse stretching under heating conditions to form geogrids with square or rectangular grids.

2、 Features and advantages

1. High strength: The biaxial stretching process enables geogrids to have high tensile strength in both longitudinal and transverse directions.

2. Corrosion resistance: the acid resistance, alkali resistance and corrosion resistance can be improved by adding anti-aging materials such as carbon black.

3. Durability: It has good anti-aging performance and long service life.

4. Lightweight: The geogrid is lightweight and easy to transport and install.

5. Soil fixation effect: closely combined with the soil, it can effectively fix the soil, prevent soil loss and landslides.

3、 Application field

Bidirectional plastic geogrids are widely used in various civil engineering projects, including but not limited to:

1. Reinforcement of embankments and roadbeds: Improving the bearing capacity and stability of the foundation.

2. Slope protection: prevent soil erosion and landslides.

3. Wall reinforcement: Enhance the stability of the wall.

4. Foundation reinforcement for large airports, parking lots, docks, freight yards, etc.: Suitable for large-area permanent bearing foundations.

4、 Precautions and Maintenance

1. Specification selection: Select appropriate specifications and models of geogrids according to the actual needs of the project.

2. Construction specifications: During the construction process, construction should be strictly carried out in accordance with relevant specifications to ensure construction quality and project effectiveness.
