Njengoba ingaphezulu le-steel-plastic geogrid lidlulela kuphethini elimaholoholo elivamile, libhekene nokumelana nokucindezeleka okukhulu kanye nokungqubuzana nokugcwaliswa, okukhawulela ukugunda, ukucindezelwa kwezinhlangothi kanye nokuphakanyiswa kwenhlabathi yesisekelo iyonke. Ngenxa yokuqina okuphezulu komcamelo wenhlabathi oqinisiwe, kuyasiza ekusakazeni nasekudluliseleni okufanayo komthwalo wesisekelo esiphezulu, futhi usakazwa phezu kongqimba lomhlabathi othambile olunomthamo omuhle wokuthwala. Ngakho-ke, yini ukusetshenziswa kwama-geogrid epulasitiki ensimbi ekumbondelekeni kwe-asphalt?
Ngenxa yokusebenza kwayo okuhle kakhulu, ngemva kokuguqulwa kwendawo kanye nokwelashwa kokumboza, izakhiwo ezingaphezulu zensimbi nepulasitiki zishintshile, izakhiwo ezihlanganisiwe zensimbi ziye zathuthukiswa, futhi ukumelana nokugqoka kanye nokumelana kwe-shear kwe-matrix kuye kwathuthukiswa kakhulu.ngcono. I-geogrid yepulasitiki yensimbi ekhiqizwe umkhiqizi we-plastic geogrid yensimbi ingadlala indima ebalulekile uma isetshenziswa ekumbondeleni kwetiyela.
Lapho izinga lokushisa liphezulu, ingaphezulu le-asphalt pavement lithambile futhi linamathela; ngaphansi kwesenzo somthwalo wemoto, indawo ye-asphalt ayikwazi ukubuyela esimweni sayo sangaphambilini. Ngemuva kokususwa komthwalo, ukuguqulwa kwepulasitiki kwenzeka. I-deformation yepulasitiki yenziwa ngaphansi kwethonya lokuqoqwa njalo nokugoqa okuphindaphindiwe kwezimoto ngesikhathi se-estrus. Ku-asphalt pavement, i-plastic geogrid yensimbi ingasabalalisa ingcindezi nengcindezi eqinile, futhi yakhe indawo yebhafa phakathi kwakho kokubili. Ukucindezeleka akushintshi ngokuzumayo kodwa kancane kancane, okunciphisa umonakalo we-asphalt pavement obangelwa ukushintsha okungazelelwe kokucindezeleka. Ngesikhathi esifanayo, ukuphakama okuphansi kunciphisa ukuchezuka komgwaqo futhi kuqinisekisa ukuthi umgwaqo ngeke udlule ukuguqulwa ngokweqile.
I-geogrid yepulasitiki yensimbi iyinto enkulu ye-geosynthetic. Inezici eziyingqayizivele nokusebenza ngempumelelo uma kuqhathaniswa namanye ama-geosynthetics. Ama-geogrid avame ukusetshenziselwa ukuqinisa izakhiwo zenhlabathi eziqinisiwe noma izinto eziyinhlanganisela. I-geogrid yensimbi-yepulasitiki yenziwe ngocingo lwensimbi olunamandla amakhulu ngokwelashwa okukhethekile, futhi idluliselwa ebhandeni eliqinile elihlanganisiwe elinamandla amakhulu eligcizelelwe phezulu ngezithasiselo ezifana ne-polyethylene noma i-polypropylene. Leli bhande elilodwa lilukiwe noma liboshiwe ebangeni elithile ngobude nangokuphambana, futhi amalunga alo ashiselwe ubuchwepheshe obukhethekile bokuqinisa nokubopha. I-geogrid eqinisiwe.
