1. Ngokumalunga nokusetyenziswa kwale mveliso ye-geotextile, indima yayo ephambili kukusebenza njengesithintelo kunye nolwazi lokucoca ukwahlula umhlaba ngokusisigxina emanzini, ekugqibeleni ukuthintela ukuqokelelwa koxinzelelo lwamanzi, kwaye emva koko uthintele umsebenzi wamanzi ekwenzeni i-corrosion.Ii-geotextiles zikwasetyenziswa ngokufanelekileyo ukwandisa imveliso yezityalo, iigadi, kunye nezindlu zokugcina izityalo.Iimpawu zabo zokukhusela zinciphisa imfuno yomsebenzi wezandla kwi-pesticides, kwaye unamathele kumda omncinci.
Ukongeza, ii-geotextile ezinxulumene ne-geotextile zisebenza njengezithintelo ezizimeleyo zamanzi omhlaba kunye nedatha yokucoca, ekugqibeleni ithintele ukuqokelelwa koxinzelelo lwamanzi, kwaye emva koko ithintele umsebenzi wamanzi ekubeni wenze umhlwa.
Isenzeko sokuba i-strain ye-filament geotextile iyanda ngokuqhubekayo kunye nexesha phantsi kwesenzo sokuqina samandla angaphandle azinzileyo kuthiwa yi-creep.Xa isetyenziswe kwiiprojekthi ezidlala indima yokucoca, ukukhupha amanzi, kunye nomqobo, i-filament geotextile ngokukhawuleza ixhomekeke kumandla angaphandle azinzileyo.Ngoko ke, iimpawu ze-pupation ze-filament geotextile zithathwa njengesalathisi sokukhetha ilaphu.I-filament geotextile idlala indima yokuqinisa, Iimpawu zayo ze-creep zinempembelelo ebalulekileyo kwisiphumo sayo sokuqinisa.I-filament geotextiles isetyenziselwa ukuqinisa i-embankments kwiziseko ezithambileyo.I-filament geotextiles iphantsi komlinganiselo othile woxinzelelo.Emva kwexesha elithile, i-filament geotextile idlula i-deformation ebalulekileyo, enokuchaphazela ukuzinza kwe-embankment.Inxalenye yomonakalo inokuthi yenzeke, njenge-deformation egqithisa ukuhlukana kwayo, kunye ne-filament geotextile cracks, enokubangela umonakalo opheleleyo kwi-embankment.Kwiiprojekthi ezinjalo, ngokuqhelekileyo kuthatha iminyaka emi-5 ukuya kwe-7 ukuhlanganisa isiseko esithambileyo.Ngeli xesha, i-creep ye-filament geotextile ayikwazi ukudlula ixabiso elicwangcisiweyo.
Ukusetyenziswa ngokuchanekileyo kunesiphumo esihle.
Kwaye ukusetyenziswa kwe-geotextiles kwiiprojekthi zokugcinwa kwamanzi kunempembelelo enhle kakhulu, kuba olu hlobo lwezinto eziphathekayo lunokuqhuba kakuhle kwamanzi, ixesha elide lokusetyenziswa, kwaye linokwethenjelwa ngokwemiqathango yokuqina.
Olu hlobo lwemveliso lunokwenza umjelo ozinikeleyo wokukhupha amanzi ngaphakathi kobunzima bomhlaba, onokuqinisekisa ukukhutshelwa ngokuchanekileyo kolwelo olugqithisileyo kunye neegesi ezithile ngexesha lokususwa kwenye inkunkuma.Oku kunokuthintela iintsalela ngaphakathi kobunzima bomhlaba kwaye kube nempembelelo ethile kwisakhiwo sobunzima bomhlaba.Oku akuchaphazeli nje kuphela ubume bobunzima bomhlaba, kodwa kunokuba nempembelelo ebalulekileyo kwimveliso elandelayo.
Kumhlaba, ngexesha lokusetyenziswa kwemveliso, kunokuthintela kwakhona ukuguqulwa komhlaba, oluncedo kakhulu ekuphuculeni ukuchasana kwe-deformation.Kwezinye iiprojekthi zokwakha, ukusetyenziswa kwe-geotextiles kunokunyusa ukuzinza kwezakhiwo.
Ngaphezu koko, i-geotextile ikwaluncedo kakhulu ekuphuculeni umgangatho wobunzima bomhlaba, obunokuqinisekisa ukuba ubunzima bomhlaba bunokuba bugudileyo ngexesha lokwakhiwa, kwaye ubunzima bomhlaba bunokukhupha ezinye izinto ezilahlwayo ukubathintela ukuba bangahlali ngaphakathi kobunzima bomhlaba, okubangela ukuba umhlaba ube mfiliba. kwimpembelelo kwisakhiwo sobunzima bomhlaba.
Ngapha koko, iimveliso ze-geotextile ezingangeni manzi ezifana ne-filament geotextile ziqhele ukusetyenziswa kwimveliso, kuba ukungena komoya kunye nokungena kwamanzi kulunge kakhulu, kwaye zithandwa kakhulu ngamashishini.Umphumo wabo ongenamanzi uthandwa kakhulu ngabavelisi.
Ukuba imathiriyeli ekrwada esetyenziselwa imveliso ikhethekile kwaye ezinye ii-polypropylene okanye ii-polyester fibers zisetyenziswa njengamafutha, isiphumo sokunganyangeki kwe-corrosion nayo ibaluleke kakhulu, enokuphucula amandla emveliso okuxhathisa ukubola kwaye ithintele ukubonakala komhlwa kwezinye izinto. emhlabeni.
Ii-geotextiles ziqhele ukusetyenziswa kwiiprojekthi ezininzi zobunjineli boluntu ukunceda kwimveliso yazo, njengoko zinokonyusa amandla okuqina kunye nokumelana noguquko lomhlaba.
Enyanisweni, olu hlobo lwe-geotextile engenamanzi lusetyenziswa ngokubanzi, kungekhona kuphela kwiiprojekthi zokugcinwa kwamanzi, kodwa nakwezinye iiprojekthi zokuthutha umzila wesitimela eziqhelekileyo, kunye nokwakhiwa, ukuqinisekisa ukuba umphumo wemveliso unokuqatshelwa ngumenzi.
