Geocell is a mesh structure formed by high-strength HDPE or PP copolymer broadband, which is welded or riveted by strong force It can stretch and fold freely during transportation, and when in use, it can be opened and filled with soil, rock or concrete materials, forming a structure with strong lateral restraint and high stiffness It can be used as a cushion layer to increase the bearing capacity of weak foundations, and can also be laid on slopes to form slope protection structures. It can also be used to construct retaining structures, reinforce foundations, and protect railway slopes The application of geosynthetic materials in highways is becoming increasingly widespread. Practice has proven that geosynthetic cells are a new type of highway construction material with more advantages, strong practicality, suitable price, and good application effects compared to other geosynthetic materials
