The Geoce1l is a 3--D structural honeycomb body.Which is n1ade of polymer through continuous hot-working method. Itis used In strengthening soft soil bed----when the thick basic layer is laid While the project is short of soil aggregate. It can powerfullyrestrict the side displacement ofaggregate and further Srengthen the bed and also meet the requirement of load--carrying capacity of the bed with limit aggregate. The Geoce1l is used in protecting the slope sur-face--wl1en planting grass is used to protect the slope where the ag-gregate is not easy to stay because of ful1 weathering .Itls simp1e in overlap between flaky materials and fast in construction.There are little holes in the connections of flaky materials and they are good for flowing water smoothly
