Njengoko umphezulu we-steel-plastic geogrid ufikelela kwipatheni eqhelekileyo erhabaxa, iphantsi koxinzelelo olukhulu kunye nokukhuhlana kunye nokuzaliswa, okunciphisa ukucheba, ukunyanzeliswa kwecala kunye nokuphakanyiswa komhlaba wesiseko ngokubanzi. Ngenxa yobunzima obuphezulu bomxokelelwano womhlaba oqinisiweyo, kukulungele ukusasazwa kunye nokuhanjiswa okufanayo komthwalo wesiseko esiphezulu, kwaye usasazwa kuluhlu olungaphantsi lomhlaba oluthambileyo olunomthamo omhle wokuthwala. Ke, yintoni ukusetyenziswa kwee-geogrids zentsimbi yentsimbi kwi-asphalt engaphezulu?
Ngenxa yokusebenza kwayo okugqwesileyo, emva kokuguqulwa komgangatho kunye nonyango lokugubungela, iipropati zentsimbi kunye neplastiki zitshintshile, iipropati ezidibeneyo zentsimbi ziphuculwe, kwaye ukuxhathisa ukugqoka kunye nokuxhatshazwa kwe-shear kwe-matrix kuye kwaphuculwa kakhulu.phucula. I-geogrid yeplastiki yensimbi eveliswe ngumvelisi we-geogrid yensimbi inokudlala indima ebalulekileyo xa isetyenziswe kwi-asphalt overlay.
Xa ubushushu buphezulu, umphezulu we-asphalt pavement uthambile kwaye uncangathi; phantsi kwesenzo somthwalo wesithuthi, indawo ye-asphalt ayikwazi ukubuyela kwimeko yangaphambili. Emva kokuba umthwalo ususiwe, ukuguqulwa kweplastiki kwenzeka. I-deformation yeplastiki yenziwe phantsi kweempembelelo zokuqokelela rhoqo kunye nokuphindaphinda ngokuphindaphindiweyo kwezithuthi ngexesha le-estrus. Kwipavumente ye-asphalt, i-geogrid yentsimbi yentsimbi inokusasaza uxinzelelo kunye noxinzelelo lwe-tensile, kwaye yenze indawo ye-buffer phakathi kwezi zimbini. Uxinzelelo alutshintshi ngokukhawuleza kodwa ngokuthe ngcembe, olunciphisa umonakalo we-asphalt pavement obangelwa utshintsho ngokukhawuleza loxinzelelo. Ngelo xesha, ubude obuphantsi bunciphisa ukuphambuka kwendlela kwaye iqinisekisa ukuba umgangatho wendlela awuyi kudlula ukuguqulwa okukhulu.
I-geogrid yentsimbi yentsimbi yeyona nto ibalulekileyo ye-geosynthetic. Ineempawu ezizodwa kunye nokusebenza kakuhle xa kuthelekiswa nezinye i-geosynthetics. Ii-geogrids zihlala zisetyenziselwa ukuqinisa izakhiwo zomhlaba eziqiniweyo okanye izinto ezidibeneyo. I-geogrid yensimbi-yeplastiki yenziwe ngocingo oluphezulu lwentsimbi ngonyango olukhethekileyo, kwaye ikhutshwe kwi-composite yebhanti yokuqina ephezulu kunye ne-embossing embossing ebusweni kunye nezongezo ezifana ne-polyethylene okanye i-polypropylene. Eli bhanti lilodwa lilukiwe okanye libotshwe kumgama othile ngobude nangokunqamlezileyo, kwaye amalungu ayo adityaniswe ngokuqiniswa okukhethekileyo kunye nobuchwepheshe bokudibanisa i-welding. Yigeogrid eyomeleziweyo.
