This document was first published in.2003 and this is the first revision.IntroductionGeocell has a unique three-dimensional structure and has outstanding engineering performance in specific application environments. The strips made of the material are connected to each other through welding, fusion, injection molding and mortise and tenon processes, and after unfolding, they are quadrilateral or polygonal honeycomb-shaped three-dimensional Grid structure. Geocell height, grid size, and strip thickness have an important impact on the engineering application of geocells. In the process, geocells of different specifications, materials and node structures can be combined with soil, sand, stone and other fillers to form geocells of different strengths and thicknesses. These composites can be placed at the required location according to the requirements of the project to reinforce the foundation, strengthen the roadbed, protect the slope, build retaining Earth walls, etc. Geosynthetics Plastic Geocell1 ScopeThis document specifies the classification and naming, materials, requirements, inspection rules, marking, packaging, storage and transportation of plastic geocells. The corresponding test methods were developed. This document is applicable to polyethylene, polypropylene, polyethylene terephthalate (hereinafter referred to as "polyester") as the main raw materials, adding necessary The production, use and sale of plastic geocells, which are made into strips through appropriate processing and then connected by various methods.2 Normative referencesThe contents of the following documents constitute essential clauses of this document through normative references in this document.
