I-Geogrid yePlastiki
Inkcazo emfutshane:
- Yenziwe kakhulu ngezinto zepolymer eziphezulu ezifana ne-polypropylene (PP) okanye i-polyethylene (PE). Ngokubonakalayo, inesakhiwo esifana negridi. Esi sakhiwo segridi senziwe ngeenkqubo ezithile zokuvelisa. Ngokubanzi, izinto eziluhlaza zepolymer zenziwa kuqala zibe yipleyiti, emva koko ngeenkqubo ezifana nokubhoboza nokusolula, i-geogrid enegridi eqhelekileyo ekugqibeleni yenziwa. Imilo yegridi ingaba sisikwere, ibe yingxande, ibe yidayimani, njl. Ubungakanani begridi kunye nobukhulu be-geogrid buyahluka ngokweemfuno ezithile zobunjineli kunye nemigangatho yokuvelisa.

Iimpawu zokusebenza
1. Iipropati zoomatshini
Inamandla okutsalwa aphezulu. I-geogrid yeplastiki eyoluliweyo ngokulinganayo inamandla okutsalwa ngokukodwa kwicala lokutsalwa kwaye inokumelana namandla amakhulu okutsalwa ngaphandle kokuqhekeka. Umzekelo, amandla okutsalwa kwezinye ii-geogrid eziyoluliweyo ngokulinganayo zinokufikelela ngaphezu kwe-100kN ngemitha, nto leyo eyenza ukuba ibe ntle kakhulu ekuqiniseni iziseko kunye nokuthintela ukufuduka komhlaba ecaleni.
I-geogrid yeplastiki eyoluliweyo kabini inamandla okutsalwa kabini alungeleleneyo kwaye inokusasaza ngempumelelo uxinzelelo. Inokuba nefuthe lokuthintela umhlaba ngaxeshanye kuzo zombini iindlela ezinde nezinqamlezileyo, iphucula ukuthembeka kunye nokuzinza kobunzima bomhlaba.
2. Ukumelana nokugqwala
Ngenxa yokuba izinto zayo eziphambili ziyi-polymers ezifana ne-polypropylene okanye i-polyethylene, inokunyamezelana kakuhle neekhemikhali ezifana nee-asidi kunye ne-alkalis. Kwezinye iindawo zomhlaba ezine-asidi ephezulu okanye i-alkalinity okanye iindawo apho izinto zeekhemikhali zinokuvuza khona, i-geogrid yeplastiki inokugcina uzinzo lwayo lokusebenza kwaye ayizukonakala ngenxa yokubola kweekhemikhali, ngaloo ndlela iqinisekisa uzinzo lwexesha elide lweprojekthi.
3. Ukumelana nokukrala
Umphezulu wayo uthambile, kodwa inokumelana nokukrweleka okuthile. Ngexesha lenkqubo yokwakha, nokuba ikhuhlana namasuntswana omhlaba kunye nezixhobo zokwakha, ayizukugugika lula kwaye inokuqinisekisa ukuba ulwakhiwo kunye nokusebenza kwe-geogrid akuchaphazeleki. Ngaphezu koko, inokumelana nokukrweleka nokukrweleka kwamasuntswana omhlaba ngexesha lokusetyenziswa ixesha elide.
4. Ukusebenza kokukhupha amanzi
Ulwakhiwo olufana ne-mesh lwe-geogrid yeplastiki luluncedo ekutsaleni amanzi. Kwezinye iiprojekthi zonyango lwesiseko ezifuna ukukhupha amanzi, lunokusebenza njengomjelo wokukhupha amanzi, luvumela amanzi angaphantsi komhlaba okanye amanzi angaphezulu ukuba aphume kwiimbobo ze-geogrid, lunciphise uxinzelelo lwamanzi kwimbobo emhlabeni kwaye lonyuse amandla okucheba komhlaba.
Iindawo zoSetyenziso
1. Ubunjineli beNdlela
Isetyenziswa kakhulu ekuqiniseni iindlela ezinkulu, oololiwe, kunye nezinye iindlela. Ukubeka i-geogrid yeplastiki ezantsi kwe-subgrade kunokunyusa amandla okuthwala kwe-subgrade kwaye kunciphise ukuhlala okungalinganiyo kwe-subgrade. Ingakumbi kwicandelo le-subgrade ethambileyo, inokusasaza ngempumelelo umthwalo wesithuthi othunyelwa kumphezulu wendlela, ithintele ukuphuma ecaleni komhlaba we-subgrade, kwaye iphucule ubomi benkonzo kunye nentuthuzelo yokuqhuba yendlela.
2. Ubunjineli boKhuseleko lweSlope
Isetyenziselwa ukuqinisa nokukhusela amathambeka. Ngokufaka i-geogrid kumhlaba othambekayo, ukuzinza komhlaba okuchasene nokutyibilika kunokwandiswa. Amandla okungqubana phakathi kwawo nomhlaba anokuthintela umhlaba ekutyibilikeni phantsi kumphezulu wethambeka, kwaye anokudlulisa umthwalo ophezulu wethambeka uye ngaphakathi komzimba wethambeka, okwenza ukuba ithambeka lihlale lizinzile xa lichaphazeleka zizinto zangaphandle ezifana nemvula - ukukhuhlana kwamanzi kunye neenyikima.
3. Ubunjineli bodonga olugcina izinto
Ukubeka i-geogrid yeplastiki kwi-backfill emva kodonga lokugcina izinto kunokunciphisa uxinzelelo olusecaleni lwe-backfill eludongeni lokugcina izinto. Ukusebenzisana phakathi kwe-geogrid kunye ne-backfill kwenza ukuba i-backfill ibe yinto epheleleyo, kwaye inxalenye yoxinzelelo olusecaleni lwe-backfill iguqulwa ibe yi-tensile force ye-geogrid, ngaloo ndlela kunciphisa umthwalo othwalwa ludonga lokugcina izinto kwaye kunciphisa ubungakanani besakhiwo kunye neendleko zodonga lokugcina izinto.
