Hdpe geocell is a civil engineering material formed by connecting sheets in a certain way, which has a three-dimensional mesh structure, vertical reinforcement effect, and effective overall confinement effect. It can ensure the minimum filling height in certain special sections to the greatest extent possible, and make the filling have high-quality strength and stiffness. The connection of geocells usually takes the form of riveting, plugging, welding, etc. The application of riveting and plug-in compartments has improved the strength of the connection points in geotechnical compartments. However, due to the use of metal connectors, they are prone to corrosion and their service life is affected in practical use. Although welded compartments have no metal connections, their welding strength is relatively low, which also has its own limitations.
