1 treatment Ubuvuzi bwa asfalt bwatewe hejuru yumuvuduko ukabije wa geogrid
Ubuso bwa geogrid bwinjijwemo ubwikorezi bwumuvuduko ukabije wogukoresha geogrid. Asfalt yatewe inda-yifata-y-igitutu-yunvikana hejuru ya geogrid nicyo kintu nyamukuru cya geosintetike ya geogrid. Ugereranije nubundi geosynthetike, HDPE geomembrane yerekana neza ukuri kwayo ningirakamaro. Geogrid ikoreshwa nkibikoresho byongera imbaraga zubutaka bwubatswe cyangwa ibikoresho byubaka bya aluminium alloy geotextile.

Geogrid igabanyijemo ibyiciro bine: geogrid ya plastike, ibyuma bya pulasitiki geogrid, fibre fibre geogrid na fibre fibre polyester geogrid. Geogrid ya plastike ni urukiramende rwose cyangwa urukiramende rwa polymer rwibikoresho byakozwe no kogosha buhoro buhoro. Ukurikije icyerekezo cyo gukuramo icyerekezo mugihe cyo gukoporora, irashobora kugabanywamo ubwoko bubiri: kogosha inzira imwe hamwe nuburyo bubiri.
Nugukubita umwobo kuri plaque zimwe na zimwe zatewe no gusohora, hanyuma ugasunika imbere icyerekezo kirambuye munsi yo gukonja. Iyo ibice bya geotextile bigera kuri 10% yubunini bwumuzingo, dukeneye gukora igice cyangiritse, hanyuma tugahuza imiraba ibiri yisi hafi. Mubyongeyeho, niba icyuho kiri hejuru yubuso kigera kuri 10% yubunini bwumuzingo, umuzingo wa geotextile ugomba kuvaho ugasimbuzwa umuzingo mushya. Ibikoresho byo gutwika bikoreshwa na geogrid geomembrane mu ruganda nyuma yubuvuzi byibasiwe n uruganda rukora ibikoresho bya asfalt.
Buri fibre irapfundikijwe rwose kandi irahujwe rwose na asfalt, kugirango tumenye neza ko ikirahuri cya fibre geogrid murwego rwa asfalt kitazacibwa mubintu bya asfalt, ariko bihujwe neza. Geogrid igomba gushyirwa kumurongo woroshye wo hasi ukurikije ingano yangiritse. Uzuza amasomo yo hejuru ntashobora gutobora imyanda ya geogrid. Iyo geogrid ishyizwe, umuvuduko wumuyaga uba mwinshi cyane kugirango wambukiranya umurongo wo hagati winkombe. Geogrid yashyizwe igihe kirekire. Gushyira bigomba gukomera kugirango birinde inkeke, kugoreka cyangwa gutobora.
Geogrid ihujwe mu buryo butambitse nuburyo bwo guhuzagurika, kandi ubunini bwo kugenda ntiburenga 20cm. Geogrid imaze gushyirwaho, gushyira intoki hejuru yuzuza ibyiciro byo hejuru bigomba guhita byuzuzwa kugirango birinde izuba umwaka wose. Noneho kora ubwikorezi bwibikoresho, kuringaniza no kuzunguruka. Gukora imashini no kuzunguruka bikorwa kuva kumpande zombi kugera kumpande zombi, kandi kuzunguruka bikorwa kuva kumpande zombi kugera kumpande zombi, kandi ubwitonzi burakomeza kugirango bigerweho burundu.
2 、 Geogrid ifite imbaraga zingana nicyuma cyoroheje
Geogrid itondekanya molekile ndende ya hydrocarubone ya polymer mumurongo ugororotse ugana icyerekezo kirambuye binyuze muburyo bwikoranabuhanga budasanzwe. Imbaraga zihuza iminyururu ya molekile irashimangirwa cyane, bityo ifite imbaraga zingana cyane no kuramba. Kurugero, imbaraga zingana zingana inshuro 5-10 kurenza iyo mbere yo kurambura, kandi kurambura ni 10% - 15% hejuru yibyo mbere yo kurambura. Imbaraga zo guhuza ibice muri gride ziriyongera, kandi coefficente yo guterana yiyongera cyane. Turashobora kuvuga ko mubintu byinshi bya geosintetike, imbaraga zingana za geogrid nizo zisumba izindi zose, kandi imbaraga zacyo zingana hafi yicyuma cyoroheje. Usibye imbaraga zayo zikomeye, geogrid nayo ifite igihe kirekire, kubera ko ibikoresho bya geogrid bikozwe muri plastike nyinshi ya polyethylene cyangwa polypropilene nkibikoresho fatizo nyamukuru, kandi bikubiyemo inyongeramusaruro zirwanya ubusaza nka UV na karubone umukara, zishobora irinde isuri yumuti kama nka aside, alkali, umunyu, inzoga, lisansi na UV. Dukurikije amakuru afatika, ubuzima bwa serivisi ya geogrid yakozwe nabakora geogrid irashobora kugera kumyaka 120 mugihe cy'ubushyuhe busanzwe no gushushanya imitwaro yemewe. Birumvikana ko impamvu ituma geogrid ikoreshwa cyane nuko geogride yasobanuwe hepfo ifite ibintu byiza biranga. Mu mushinga wo gutunganya ahantu hahanamye, geocell ya plastike yumushinga wa geogrid, nyuma ya geocell imaze kwagurwa no gukingurwa, ikerekana ubuki bwubuki butatu bwa geocell, kandi bwuzuza geocell isi n amabuye cyangwa ibikoresho bya beto kugirango bibe imiterere ifite inzitizi zikomeye kandi gukomera gukomeye kugirango bigire ingaruka zihamye kumurongo. Irashobora kandi guhinga ibimera bimwe na bimwe, cyangwa ibihuru bito hamwe n’ibindi bimera muri geogrid, bigakora ibinyuranyo bitandukanye bya fibre fibre ni ibintu nyamukuru bya geosintetike, bifite imikorere ningaruka ugereranije nibindi bikoresho bya geosintetike. Ikirahuri cya fibre ya fibre ikoreshwa muburyo bwo gushimangira ubutaka bwubatswe cyangwa ibikoresho
