The geocell is a three-dimensional grid cell structure formed by reinforced HDPE material with ultrasonic welding. And it is a three-dimensional network after being ex- panded. Due to engineering needs, some holes are punched in the diaphragm. It is mainly divided into geocell, high-strength geocell, and honeycomb restraint sys- tem (Honeycomb restraint system: it is a three-dimensional network made of polymer broadband with ultrasonic welding, and the cells constitute a strong lateral restraints and stiffness structure by filling with materials such as sand, stone or concrete).
It is mainly used in foundation reinforcement, soft foundation treatment, steep slope protection, landslide prevention, load-bearing gravity hybrid wall, and it is especially suit- able for weathered mountain forests, deserts and swamps.
