Geotextilesngamalaphu avuzayo athi, xa esetyenziswa ngokudityaniswa nomhlaba, abe nako ukwahlula, ukuhluza, ukuqinisa, ukukhusela okanye ukukhupha amanzi.Ngokuqhelekileyo zenziwe nge-polypropylene okanye i-polyester, amalaphu e-geotextile eza kwiindlela ezintathu ezisisiseko: ezilukiweyo (ezifana nebhegi ye-imeyile), inaliti ehlatywayo (efana nokuziva), okanye ibhondi yobushushu (efana ne-ayini ye-ayini).
Ii-geotextile composites ziye zaziswa kwaye iimveliso ezifana ne-geogrids kunye ne-meshes ziye zaphuhliswa.I-Geotextiles yomelele, kwaye iyakwazi ukuthambisa ukuwa ukuba umntu uyawa.Ngokubanzi, ezi zixhobo zibizwa ngokuba yi-geosynthetics kunye noqwalaselo ngalunye-i-geonets, i-geosynthetic clay liners, i-geogrids, i-geotextile tubes, kunye nezinye-zinokuvelisa izibonelelo kwi-geotechnical kunye noyilo lobunjineli bokusingqongileyo.
Imbali
Ngamalaphu e-geotextile asetyenziswa rhoqo kwiindawo ezisebenzayo zanamhlanje, kunzima ukukholelwa ukuba le teknoloji ayizange ibekho kumashumi asibhozo eminyaka eyadlulayo.Le teknoloji iqhele ukusetyenziselwa ukwahlula iileya zomhlaba, kwaye iye yajika yaba lishishini leebhiliyoni zeedola.
I-Geotextiles ekuqaleni yayijongwe ukuba ibe yenye indawo kwizihluzi zomhlaba wegranular.Eyoqobo, kwaye isasetyenziswa ngamanye amaxesha, igama le-geotextiles ngamalaphu okucoca.Umsebenzi waqala ngeminyaka yoo-1950 kunye no-RJ Barrett esebenzisa i-geotextiles ngasemva kweendonga zolwandle zekhonkrithi ezibekwe ngaphambili, phantsi kweebhloko zokulawula ukhukuliseko lwekhonkrithi, ngaphantsi kwe-riprap enkulu yamatye, nakwezinye iimeko zolawulo lokhukuliseko.Wasebenzisa izitayile ezahlukeneyo zamalaphu e-monofilament elukiweyo, zonke ziphawulwa ngepesenti ephezulu yendawo evulekileyo (eyohluka ukusuka kwi-6 ukuya kwi-30%).Uxoxe ngesidingo sokungena okwaneleyo kunye nokugcinwa komhlaba, kunye namandla okwaneleyo elaphu kunye nobude obufanelekileyo kwaye usete ithoni yokusetyenziswa kwe-geotextile kwiimeko zokuhluza.
Usetyenziso
I-Geotextiles kunye neemveliso ezinxulumene nazo zinezicelo ezininzi kwaye ngoku zixhasa izicelo ezininzi zobunjineli boluntu kubandakanya iindlela, amabala eenqwelomoya, oololiwe, ii-ebankments, izakhiwo zokugcina, amadama, imijelo, amadama, ukhuseleko lwebhanki, ubunjineli bonxweme kunye neendawo zokwakha i-silt ucingo okanye i-geotube.
Ngokuqhelekileyo i-geotextiles ibekwe kwindawo yoxinzelelo ukuqinisa umhlaba.Ii-geotextiles zikwasetyenziselwa ukuxhobisa iindunduma zentlabathi ukukhusela ipropathi eselunxwemeni elunxwemeni kwizaqhwithi, intshukumo yamaza kunye nezikhukhula.Isikhongozeli esikhulu esizaliswe yintlabathi (i-SFC) ngaphakathi kwenkqubo yeengqumba zentlabathi ithintela ukhukuliseko lwesiphango ekubeni luqhubele ngaphaya kwe-SFC.Ukusebenzisa iyunithi ethambekileyo kunetyhubhu enye kuphelisa ukuhlazeka okwenzakalisayo.
Iimanuwali zolawulo lokhukuliseko zihlomla malunga nokusebenza kweemilo ezithambekileyo, ezinyathelweyo ekudambiseni umonakalo wokhukuliseko lonxweme olusuka kwiinkqwithela.Iiyunithi ezizaliswe yisanti ye-Geotextile zibonelela ngesisombululo "esithambileyo" sezixhobo zokukhusela indawo ephezulu.I-Geotextiles isetyenziswa njengokulinganisa ukuzinzisa ukuhamba kwimijelo yomlambo kunye ne-swales.
I-Geotextiles inokuphucula amandla omhlaba ngexabiso eliphantsi kunezikhonkwane zomhlaba eziqhelekileyo.Ukongezelela, i-geotextiles ivumela ukutyala kwiindawo ezinqabileyo, ukukhusela ngakumbi ukuthambeka.
I-Geotextiles isetyenziselwe ukukhusela ifossil hominid footprints yaseLaetoli eTanzania kukhukuliseko, imvula, kunye neengcambu zemithi.
Ekwakheni ukudilizwa, amalaphu e-geotextile adityaniswe nocingo lwentsimbi yokubiyela anokuqulatha inkunkuma eqhumayo.
