Hdpe geocell is a new type of high-strength geosynthetic material that is currently popular both domestically and internationally. Hdpe geoecell is a three-dimensional mesh structure formed by high-strength welding of reinforced HDPE sheet material. Hdpe geocell has flexible expansion and contraction, can be transported and stacked, and can be stretched into a mesh during construction, filled with loose materials such as soil, gravel, and concrete, forming a structure with strong lateral restraint and high stiffness. Hdpe geocell has the characteristics of light material, wear resistance, stable chemical properties, resistance to light and oxygen aging, acid and alkali resistance, etc. Due to its high lateral restraint and anti slip, anti deformation, effective enhancement of roadbed bearing capacity and load dispersion, hdpe geocell is currently widely used in cushion layers, stable railway subgrades, stable road soft foundation treatment, support structures for pipelines and sewers, mixed retaining walls to prevent landslides and bear gravity, desert, beach and riverbed, riverbank management, etc.
