The progress of science has led to the continuous emergence of new materials, which provides more possibilities for improving engineering quality and reducing engineering costs. Among them, HDPE (high density polyethylene) geocell, as an important geosynthetic material, has been widely used in the fields of foundation reinforcement, slope protection, desert treatment and so on because of its unique structure and properties.
HDPE geocell is a three-dimensional mesh structure material, which has high strength, corrosion resistance, aging resistance and good mechanical properties. According to civil engineering expert Professor Zhang pointed out: "HDPE geocell can effectively improve the bearing capacity of the foundation, reduce the settlement of the roadbed, and extend the service life of the road." In practical engineering, for example, HDPE geocell is used in the construction of a highway to treat soft soil foundation. The results show that the bearing capacity of the foundation is significantly improved and the stability of the subgrade is strengthened after the addition of the geoglage.
In addition, compared with the traditional slope protection method, the slope laid by HDPE geocell has higher vegetation coverage and stronger resistance to rain erosion. Dr Li, an environmental scientist, said: "HDPE geocell can help plant roots grow, form a stable ecological slope protection, and play a positive role in preventing soil erosion."
Combined with relevant research data at home and abroad, the application of HDPE geocell on sandy ground also shows obvious advantages. In a study of desert highway construction, HDPE geocell is used to fix sand layer. The results show that this method can effectively prevent dune movement, reduce wind erosion, and ensure the stable operation of the road.
