Plastiki geogrid rudzi rutsva rwepolymer zvinhu zvakagadzirwa munharaunda yanhasi. Mushure me bidirectional directional kutambanudza, zvinyorwa zvine yunifomu refu uye transverse tensile simba, yakanaka ductility, yakanyanya kuneta kuramba uye kuita kwakanaka. Mukuchengetedza dhizaini yekudzivirira, zvinodikanwa kunyatso tarisa uye kusarudza zvinhu zvine kuomarara mameseji uye yunifomu particle size. Nezve jecha cushion yekuchenesa svikiro uye jecha rakaomarara, madhaka ari pasi pe5%, chinangwa ndechekugadzira chiteshi chemvura.
Plastiki geogrid inogadzirwa neyepamusoro molecular polymer kneading, kugadzira ndiro, uye kutambanudza kureba uye nechemberi mushure mekubaya. Izvo zvinhu zvine simba rakakura rekusimba mune yelongitudinal uye yakachinjika mafambiro, uye chimiro chinogona kupawo mutoro unoshanda uye wakasununguka wakanakira kupindirana system muvhu, uye inoshandiswa pakusimbisa hwaro hwekuremerwa kwehukuru.
Nekuda kwekuti mapurasitiki geogrids akanganiswa nemamiriro ekunze, mainjiniya epasi pevhu anofanirwa kufunga zvakanyanya kukuvadza kwemvura yepasi, uye kutora nzira dzinoshanda dzekudzivirira kunyura kwemvura yepasi, ngura uye kukuvara. Kana nguva yemvura yasvika, kusaenzana kwepamusoro pemugwagwa kana kuunganidzwa kwemvura kunofanira kugadziriswa uye kupedzwa nenguva. Mabasa mazhinji ekongiri anoratidzwa kumhepo, kwete kunyudzwa mumvura.
Iyo yenzira mbiri yepurasitiki geogrid inoshandiswa sedhiri pamwe chete nejecha cushion kana kuzadza layer. Iyi layer ine kuomarara kwakasiyana kubva paroadbed uye hwaro kana hwaro hwakapfava. Ndiyo inochinjika raft hwaro hwe embankment uye drainage chiteshi chenheyo uye ivhu rakapfava. Mvura yakawandisa inogona kurasikirwa kuburikidza negrid infiltration, kusanganiswa kwezvinhu zvakasiyana-siyana, saka, nheyo deformation iyunifomu, uye kusiyanisa kugadzirisa kuduku.
