Geogrid yakakura geosynthetic zvinhu, ine yakasarudzika mashandiro uye kugona zvichienzaniswa nezvimwegeosyntheticzvinhu.Inowanzo shandiswa sekusimbisa kune yakasimbiswa ivhu zvimiro kana composite zvinhu.Geogrids akakamurwa kuita zvikamu zvina: epurasitiki geogrids, simbi epurasitiki geogrids, girazi faibha geogrids, uye polyester warp yakarukwa polyester geogrids.Grille igridi ine mativi maviri kana matatu-dimensional grid ine humwe hurefu hwakagadzirwa ne thermoplastic kana kuumbwa yakakwirira polymer zvinhu zvakaita sepolypropylene uye polyvinyl chloride.Kana ichishandiswa muinjiniya yehurumende, inonzi geogrid.
Nekuda kwekuoma kwakashata uye deformability, simende kongiri pavement inopinda munzvimbo isina kuenzana yekugara, iyo inoshandura mamiriro ekushushikana uye mamiriro ekushanda, inowedzera kushushikana kwemukati kwekongiri zvidhinha, zvichitungamira kune yakakuvadzwa kongiri zvidhinha uye kuderedza hupenyu hwekongiri pavement.
Nzira yekugadzirisa dambudziko iri uye kudzivirira kukanganisa kwemugwagwa?Hunhu hwakanakisa hwegeogridsuye kurapwa kwakakosha kwepamusoro kune mhedzisiro mitatu.Chekutanga, kuisa ma geogrids kunowedzera kusimba kwese kwechigadziko pane lime ivhu pamusoro peiyo base layer.Wobva wapfapfaidza the layer ye hydrothermal asphalt heavy oil (oiri kana binder layer), iyo inogona kunyatso kudzivirira kukukurwa kwemvura inonaya lime ivhu pamusoro peiyo base material layer, nokudaro kuwedzera hupenyu hwelime ivhu.Chechipiri,geogridsinogona kunyatso kudzivirira kutsemuka pasimende pavement inokonzerwa nekuderera kwekushisa shrinkage nekuda kwekuneta kwemadota epasi uye ivhu.
Geogrid yakasimbiswa kongiri inogona kushanda senhengo inosimbisa yekongiri yayo yakasimbiswa, uye kushushikana kwemutoro wemumugwagwa kunogona kupararira zvakaenzana kudzivirira kuputsika kwekuratidzira, nekudaro vachiwedzera hupenyu hwesevhisi yekongiri yakarongwa.
