Isubiramo ryibanze ryimikorere ya Geosynthetic-ishimangirwa na Gari ya moshi

Inkuru bitarenze Ukuboza 2018

Mu bihe byashize, amashyirahamwe ya gari ya moshi kwisi yose yitabaje gukoresha geosynthetike nkigisubizo gito gihenze kugirango ballast ihindurwe.Muri iyi myumvire, ubushakashatsi bwimbitse bwakozwe ku isi hose kugirango harebwe imikorere ya ballast ya geosynthetic-yongerewe imbaraga mu bihe bitandukanye byo gupakira.Uru rupapuro rusuzuma inyungu zinyuranye inganda za gari ya moshi zishobora kugeraho kubera imbaraga za geosintetike.Isubiramo ry'ubuvanganzo ryerekana ko geogrid ifata ikwirakwizwa rya ballast, igabanya urugero rwo gutura burundu kandi igabanya ibice byacitse.Geogrid nayo yabonetse kugirango igabanye urugero rwo kwikuramo volumetric muri ballast.Muri rusange kunoza imikorere bitewe na geogrid byagaragaye ko ari imikorere yimikorere yimikorere (φ).Byongeye kandi, ubushakashatsi bwanagaragaje uruhare rwinyongera rwa geogride mukugabanya inzira zitandukanye no kugabanya imihangayiko kurwego rwo hejuru.Geosynthetike wasangaga ari ingirakamaro mugihe inzira zihagaze kuri subgrades yoroshye.Byongeye kandi, inyungu za geosynthetike muguhagarika ballast wasangaga ziri hejuru cyane iyo zashyizwe muri ballast.Ahantu heza hashyirwa geosynthetike havuzwe nabashakashatsi benshi ko bagera kuri mm 200-250 munsi ya sofit yo kuryama kugirango uburebure bwa ballast busanzwe bwa mm 300-350.Iperereza ryinshi ryakozwe hamwe na gahunda yo gusubiza mu buzima busanzwe kandi ryemeje uruhare rwa geosynthetics / geogride mu guhagarika inzira bityo bigafasha mu gukuraho umuvuduko ukabije washyizweho mbere, no kongera igihe hagati y’ibikorwa byo kubungabunga.
