Hari itandukaniro rinini hagati ya geogrid y’icyerekezo kimwe na geogrid y’icyerekezo bibiri mu buryo bwinshi. Ibi bikurikira ni ibanze rirambuye rya siyansi ikunzwe:
1Icyerekezo cy'imbaraga n'ubushobozi bwo gutwara imizigo:
Undirectional geogrid: Ikiranga cyayo cy'ingenzi ni uko ubushobozi bwayo bwo kwihanganira imizigo mu cyerekezo kimwe gusa, ni ukuvuga ko ikwiriye cyane cyane gutwara imbaraga z'ubutaka mu cyerekezo kitambitse, ibyo bikaba bigira ingaruka zikomeye ku buryo ubutaka buguma mu buryo buhamye. Ubusanzwe, izo grille zihuza inkoni z'inkingi n'ubutaka bw'inkingi kugira ngo zongere ubushobozi bwazo bwo gutwara imizigo no kuyirinda.
Geogrid ya Biaxial: Igaragaza ubushobozi bwo gutwara imizigo bwinshi kandi ishobora kwihanganira imizigo yaba igororotse cyangwa ihagaze. Imiterere yayo yo gutwara imizigo mu mpande zombi ituma ikoreshwa cyane mu rwego rwo gukomeza ubutaka no kubukomeza, cyane cyane ikwiriye inyubako nini, imirimo yo gutunganya ubutaka n'ibikorwa remezo.
2 Imiterere n'Imikorere:
Geogrid y’icyerekezo kimwe: ikozwe muri polymeri nini cyane (nka PP cyangwa HDPE) Nk’ibikoresho by’ibanze, ikorwa hakoreshejwe uburyo bwo kunanura uniaxial. Muri ubu buryo, molekile z’uruhererekane rwa polymeri zihindurirwa icyerekezo kandi zigashyirwa ku murongo kugira ngo zikore imiterere miremire y’urusobe rw’inyuma rufite imbaraga nyinshi n’imbaraga nyinshi z’udutsiko, kandi imbaraga zo kunanura zishobora kugera kuri 100-200 Mpa, hafi y’urwego rw’icyuma cyoroshye.
Geogrid ya Biaxial: Hashingiwe ku kurambura uniaxial, irushaho kurambuka mu cyerekezo gihagaze, kugira ngo igire imbaraga nyinshi zo gukurura haba mu cyerekezo kirekire ndetse no mu cyerekezo cyayo. Iyi miterere ishobora gutanga uburyo bwiza bwo gutwara imbaraga no gukwirakwiza mu butaka, kandi ikongera cyane ubushobozi bwo gutwara bw'ifatizo.
3 Ahantu ho gushyira mu bikorwa:
Unidirectional geogrid: Kubera imbaraga zayo zo gukomera no koroshya kubaka, ikoreshwa cyane mu gushimangira ishingiro ryoroshye, gukomeza sima cyangwa inzira za kaburimbo, gukomeza imisozi y’inkombe n’inkuta zirinda ibidukikije n’indi mirima. Byongeye kandi, yanagize uruhare runini mu gucunga imyanda no gukumira isuri y’ubutaka.
Imiterere y’ubutaka: Kubera imiterere yayo yo gutwara imizigo mu cyerekezo cy’ibiri n’imbaraga nyinshi, ikwiriye cyane ahantu hanini kandi hagoye h’ubuhanga, nko gukomeza inzira z’umuhanda n’inzira z’umuhanda mu mihanda minini, gari ya moshi, n’ibibuga by’indege, gukomeza ishingiro ry’aho imodoka nini zihagarara n’aho imizigo ikorera, no gukomeza kurinda imihanda no gushimangira imiyoboro y’amabuye y’agaciro, n’ibindi.
Muri make, hari itandukaniro rinini hagati ya geogrid y’icyerekezo kimwe n’iy’icyerekezo cy’imipaka ibiri mu bijyanye n’icyerekezo cy’imihangayiko, ubushobozi bwo gutwara imizigo, imikorere y’imiterere n’ibice bikoreshwa. Amahitamo agomba gusuzumwa hakurikijwe ibikenewe mu buhanga bwihariye.
