What is a geocell?

Geocell is a kind of high molecular polymer. It is a geosynthetic material that is welded back and forth by HDPE sheet polymer or high-strength polypropylene sheet (PP) through high-strength welding points. Because of its high-strength tensile and compressive capabilities, and its convenient transportation and simple construction, the most important thing is that it can save a lot of earthwork in the roadbed reinforcement and repair, and it is an ideal geosynthetic material.

Geocell size specifications

Geocells are divided into two types: ordinary geocells and high-strength geocells. The tensile strength of ordinary sheets is not less than 23MPa, and the tensile strength at the solder joints is not less than 100N/CM, while the high-strength geocell is a piece of The tensile strength of the material is not less than 200MPa, and the tensile strength of the solder joint is not less than 150N/CM. The thickness of its HDPE or polypropylene (PP) sheet has a thickness of 1 and the error does not exceed 0.05, where 1 thickness refers to a thickness of 1 mm. General geocells are divided into several specifications such as 5 cm high, 8 cm high, 10 cm high, 15 cm high, and 20 cm high. They all comply with the national standard of GB/T 19274-2003.

It is reported that as early as the 1970s and 1980s in Europe and the United States, geocells were widely used in roadbeds, slope protection, river courses and desert engineering and other fields, and were unanimously recognized and praised by GRI-GM13 (International Geotechnical Association). With the rapid development of our country's economy, and at the same time vigorously developing transportation network construction and urban construction, geocells play an irreplaceable role in engineering, and the most important.
