I-Geonet iyisakhiwo se-polymeric mesh se-three-dimensional esakhelwe ukuhlinzeka ngokuhambisa amanzi okuphezulu ngaphakathi kwenhlabathi kanye nezinhlelo ze-aggregate. Ngokungafani nezingqimba zokuhambisa amanzi ze-granular zendabuko ezincike ku-gravel noma kuma-sand blankets, i-geonet ihlinzeka ngokusebenza okuphezulu kwe-hydraulic ngenkathi ithatha ingxenye encane yesikhala nesisindo. Lesi sixazululo sokuhambisa amanzi se-geosynthetic sakhiwa ngokuhlanganisa noma ngokuluka izimbambo ze-polymer ezihlangana, ngokuvamile ezivela ku-high-density polyethylene (HDPE) noma i-polypropylene (PP), okudala inethiwekhi yemigudu evulekile ehambisa ngokushesha amanzi, i-leachate, noma igesi eduze kwendiza yayo. Ngenxa yokuthi ukuhlangana kwezimbambo kudala isikhala esingenalutho esimelana nokucindezelwa ngaphansi kwemithwalo yenhlabathi, i-geonet igcina ukudluliswa kwamanzi ngisho nalapho igqitshwe ekujuleni okukhulu ngaphansi kwemigwaqo, izindawo zokulahla udoti, noma izakhiwo ezibambayo. Onjiniyela bomphakathi kanye nabaklami be-geotechnical baye baphendukela kakhulu kubuchwepheshe be-geonet njengendlela esheshayo, ethembekile, futhi engabizi kakhulu kunezingqimba zokuhambisa amanzi ze-aggregate eziwugqinsi, okuyenza ibe yisisekelo sokuklama kwesimanje kokuhambisa amanzi kwe-geosynthetic.

Isakhiwo sangaphakathi se-geonet ejwayelekile sakhiwe amaqembu amabili emigqa ye-polymer ehambisanayo, eqondiswe nge-engeli komunye nomunye futhi ehlanganiswe ezindaweni zayo zokuhlangana, yakhe iphethini elingana nedayimane noma elingana nonxande elichaza izimbobo. Lesi sakhiwo se-bi-planar sinikeza into leyo ukuguquguquka kwayo okujwayelekile, okuyivumela ukuthi ihambisane nezingqimba ezingalingani kahle kuyilapho igcina indlela yokuhambisa amanzi eqhubekayo emhlabeni wayo. I-resin eyisisekelo esetshenziswa ekukhiqizeni i-geonet—ngokuvamile i-UV-stabilized HDPE noma inhlanganisela ye-PP—inikeza ukumelana okuhle kakhulu nokuhlaselwa ngamakhemikhali, ukubola kwezinto eziphilayo, nokuqhekeka kwengcindezi yemvelo phakathi namashumi eminyaka okuphila kwayo. Imikhiqizo eminingi ye-geonet iphinde ikhiqizwe ngesimo se-co-extruded esihlanganisa ungqimba lwe-nonwoven geotextile oluhlanganisiwe ohlangothini olulodwa noma kuzo zombili izinhlangothi, kwakhe i-geocomposite enikeza ukuhlunga, ukuhlukanisa, nokuhambisa amanzi emkhiqizweni owodwa. Ukuqonda lokhu kwakheka kwesakhiwo kubalulekile konjiniyela abadinga ukuqhathanisa amazinga okuhamba, ukumelana nokucindezelwa, nokuziphatha kwe-creep yesikhathi eside lapho baklama izinhlelo zokuhambisa amanzi. Ngokukhethwa kwezinto ezifanele, i-geonet ingasebenza ngempumelelo iminyaka engaphezu kwamashumi amahlanu ezinhlelweni ezinzima ezifana nokugcinwa kwemfucuza eqinile nokulawulwa kwamanzi angaphansi komhlaba.

Izinzuzo eziphawuleka kakhulu ze-geonet zisekhonweni layo eliphakeme lokuhambisa amanzi nokugeleza ngaphakathi kwendawo, okuvame ukudlula amandla okudlulisa amanzi ezingqimbeni zamatshe ngamanani amakhulu kakhulu ngeyunithi ngayinye yendawo yesiphambano. Amanzi noma i-leachate engena ku-geonet iyabanjwa futhi idluliselwe eceleni emiseleni evulekile, iyihambise ngokushesha ibheke emapayipini okuqoqa, emiseleni yaphansi, noma ezakhiweni zokuphuma ngaphandle kokuncika ekugelezweni okubangelwa amandla adonsela phansi emithonjeni enezimbotshana. Leli khono lokugeleza okuphezulu lihumusha ngqo ezinzuzweni zobunjiniyela bomphakathi ezilinganisekayo, okuhlanganisa ukukhipha amanzi ngokushesha ezindaweni ezingaphansi ezigcwele amanzi, ukunciphisa amandla e-hydrostatic uplift ngaphansi kwezinhlelo zomgwaqo, kanye nokususa ngempumelelo i-methane namanye amagesi akhiqizwa ezindaweni zokulahla imfucuza yomphakathi. Uma kuhlangene nendwangu yokuhlunga engelona i-woven ku-geonet geocomposite configuration, uhlelo luphinde luvimbele izinhlayiya zomhlabathi ezincane ukuthi zingangeni emgodini wokudonsa amanzi, luvikele ingqalasizinda yokuqoqa engezansi ekuminyaneni futhi lwandise izikhathi zokunakekela. I-geonet yokudonsa amanzi ehlolwe emkhakheni wangempela ngakho-ke inikeza iminyaka yokusebenza okuthembekile kwe-hydraulic ngenkathi abaklami bezakhiwo besizakala ngezigaba zomgwaqo ezincane kanye namaphrofayili aphelele asebenza kahle kakhulu.

Ngaphandle kokudonsa amanzi, i-geonet isebenza njengengqimba ephumelelayo yokuhlukanisa nokusabalalisa umthwalo, ikakhulukazi lapho ihlanganiswa ne-geocomposite assembly ene-geotextiles ehlanganiswe ngokushisa ebusweni obubodwa noma kokubili. Isakhiwo esihlanganisiwe sihlukanisa ngokomzimba ama-aggregate asisekelo ahlanzekile kwinhlabathi ebuthakathaka yomgogodla, siqede ukungcoliswa kwengqimba eyimbudumbudu futhi sigcine amandla ayo okuthwala umthwalo ngokuhamba kwesikhathi. Umongo we-geonet futhi unomthelela omncane wokuqinisa ngokudonsa, usabalalisa izingcindezi zasendaweni endaweni ebanzi futhi unciphisa ukuhlala okuhlukene ezimeni zenhlabathi ethambile. Ngokombono wezomnotho wephrojekthi, i-geonet inenzuzo enkulu yezindleko ngoba ithatha indawo yezendlalelo ezinobukhulu bezinto ezimbudumbudu ezilethwayo, inciphisa umthamo wokumba, futhi isheshisa izinhlelo zokwakha kakhulu. Ukufakwa kulula; amaroli angasatshalaliswa ngesandla noma ngomshini olula, anqunywe ngemimese ejwayelekile yokusebenza, futhi ahlanganiswe emaphethelweni awo; akukho mfuneko yokuqeqeshwa okukhethekile kweqembu noma imishini esindayo. Ukonga okunqwabelanayo ekuthuthweni kwezinto, amahora okusebenza, nokuqashwa kwemishini kuvame ukukhonjwa njengesizathu esiyinhloko sokuthi amaphrojekthi amaningi engqalasizinda manje acacise izindlela zokudonsa amanzi e-geosynthetic ngaphambi kwamadizayini ajwayelekile.

Ukuhlala isikhathi eside nokumelana namakhemikhali nakho kuyizinzuzo ezichazayo zemikhiqizo ye-geonet yekhwalithi, ikakhulukazi leyo eyenziwe nge-resin ye-HDPE ezinzile. Lawa ma-polymer amelana kakhulu nama-asidi, ama-alkali, amanzi anosawoti, ama-hydrocarbon, kanye nendawo enamakhemikhali anobudlova ekhiqizwa ngesikhathi sokubola kwemfucuza, ngakho-ke inethiwekhi yokudonsa amanzi ihlala isebenza isikhathi sonke sokuphila komklamo wephrojekthi. I-geonet eyakhiwe kahle iphinde imelane nokuhlaselwa kwezinto eziphilayo ezivela kuma-microbe, isikhunta, kanye nokungena kwezimpande, igcina izakhiwo zayo ze-hydraulic ngaphakathi kwamaseli okulahla imfucuza, izindawo zokukhipha amaminerali e-heap-leach, kanye namasimu ezolimo. Ukumelana nokugcina, okungukuthi, ikhono lezinto zokugwema ukuguquguquka okuncike esikhathini ngaphansi komthwalo oqhubekayo, kwakhiwa ngokucophelela kokukhethwa kokuqina kwe-resin, i-geometry yombambo, kanye nokulawulwa kwenqubo yokukhiqiza, ngakho-ke i-geonet igcina isakhiwo sayo esingenalutho ngisho ngaphansi kwenhlabathi ejulile yokumboza noma imithwalo yamaphoyinti egxilile. Abakhiqizi abaningi baqinisekisa lezi zici zesikhathi eside ngezindlela zokuhlola ezisheshisiwe, okunikeza abacacisi isiqiniseko sokuthi bakhetha umkhiqizo onomlando wokusebenza oqinisekisiwe. Ngakho-ke i-geonet ayiyona nje indlela yokudonsa amanzi eshibhile kodwa iyinto yobunjiniyela eqinile ngokwayo.

Ukuhlelwa kwamanzi emigwaqweni nasezindaweni ezihamba kuyo kumelela isigaba esisodwa esikhulu kunazo zonke sokusetshenziswa kwe-geonet, lapho ibamba khona amanzi angaphansi komhlaba futhi iwaqondise kude nesakhiwo somgwaqo ukuze kuvinjelwe ukuwohloka okungafanele. Ifakwa phakathi komhlabathi ongaphansi nesendlalelo esiyisisekelo, noma eduze kwezindonga zomsele eceleni komgwaqo, i-geonet yokuhlela amanzi iqoqa imvula engenile namanzi e-capillary bese iwathumela emiseleni yokuhlela amanzi emaphethelweni noma emiseleni yokubamba amanzi, igcina izendlalelo zesakhiwo zomile. Lesi senzo sokuhlela amanzi sinciphisa ngqo imiphumela yemijikelezo yokukhithika nokuncibilika, ukuguguleka kwezinhlayiya ezincane ezisuka esisekelweni, kanye nokukhuphuka kukadaka ogcwele amanzi phezulu ngokusebenzisa izihlanganisi zomgwaqo, konke lokhu okungafinyeza kakhulu isikhathi sokusebenza komgwaqo. Imigwaqo emikhulu, izindiza zezindiza, kanye nemigwaqo yomasipala konke kuyazuza ekufakeni isendlalelo se-geonet esiphambanayo noma eside ngaphansi kwesendlalelo esingaphezulu, lapho sisusa khona ngokuqhubekayo umswakama obungathambisa izendlalelo ezingaboshiwe. Ama-ejensi okugcina imigwaqo eNyakatho Melika naseYurophu abhale ukuncipha okukhulu kokuqhekeka, imigodi, kanye nokwehluleka komhlabathi ongaphansi ngemuva kokufaka kabusha izigaba ezimanzi ngezingubo zokuhlela amanzi ezivundlile ezakhiwe ngama-geonet anokugeleza okuphezulu.

I-Landfill engineering iyimakethe enkulu kakhulu yobuchwepheshe be-geonet, lapho yenza imisebenzi ebalulekile kukho kokubili ukutholwa kwe-leachate nezinhlelo zokukhipha igesi. Ngaphansi kwesisindo semfucuza, i-geonet yokudonsa amanzi ivamise ukufakwa ngaphezu kwe-geomembrane liner, ngokuvamile njengengxenye ye-geocomposite, ukuqoqa uketshezi olungena ngaphakathi kudoti futhi luludlulisele emachibini e-leachate nasemithonjeni yokumpompa. Ngasohlangothini lwesembozo sendawo yokulahla imfucuza, izingqimba ze-geonet zisetshenziselwa ukukhipha i-methane nezinye izingesi zokubola ziye kuma-collection headers kuyilapho futhi zidonsa amanzi emvula angena ohlelweni lokugcina lokuvala, ukuvimbela ukuqongelela kwengcindezi ye-hydrostatic esembozweni esingaphansi esingangenisi kalula. Amandla amakhulu okuhamba kwamanzi kanye nokumelana namakhemikhali kwe-HDPE geonet kuyenza ifaneleke kakhulu endaweni enzima yamangqamuzana okulahla imfucuza kamasipala nengozi, lapho ama-leachate anolaka kanye namazinga okushisa aphezulu kungabola ngokushesha izinto ezingaphansi. Abaklami bezindawo zokulahla imfucuza baphinde bacacise i-geonet emiseleni yokukhipha igesi, kuma-interlift drainage blankets, nasemisebeni yokunweba eqondile, ngayinye idinga indlela yokugeleza enokuthembeka namandla aphezulu ezindaweni eziminyene. Ukuze uthole incazelo ejulile yokuthi ama-geonet kanye nezingqimba zokuvimba ezihambisana nawo zisebenza kanjani ezindaweni zokuvalela, hlola i-Indawo Yokulahla Imfucuza ikhasi ku-Geofantex, elichaza ngokukhethwa komkhiqizo wezinhlelo zokuvimbela ukuvuza nokudonsa amanzi.

Ukuzinzisa umthambeka kanye nokukhipha amanzi odongeni olubambayo kuyizinto ezisetshenziswayo ezibaluleke ngokulinganayo, lapho i-geonet ivimbela ukunqwabelana ngokushesha komfutho wamanzi ngemuva kobuso besakhiwo noma ngaphakathi kwengqimba yomthambeka oqinisiwe. Lapho udonga olubambayo lungenakho ukukhipha amanzi okwanele, izingcindezi ze-hydrostatic zingaphinda kabili noma kathathu amandla asemaceleni okumele udonga lumelane nawo, okuholela kaningi ekuhlulekeni okuphelele noma ekususweni okukhulu kodonga nokuqhekeka ngokuhamba kwesikhathi. Ukufaka ingubo yokukhipha amanzi ye-geonet ngqo ebusweni bokugcwalisa, ngokuvamile kuhlangene ne-filter geotextile ukuvimbela izinhlayiya ezincane, kwakha indlela enokumelana okuphansi ukuze amanzi angaphansi komhlaba aphume ngezimbobo zokukhipha amanzi ezingxenyeni eziphansi. Umgomo ofanayo uyasebenza ezindongeni zomhlaba oqinisiwe ngomshini (MSE) kanye namathambeka omhlaba aqinisiwe, lapho amashidi e-geonet asongelwe evimba amanzi angaphansi komhlaba angena eceleni kwentaba yemvelo ngaphambi kokuba agcwalise indawo eqinisiwe. Impahla ye-geonet isetshenziswa kabanzi futhi ngaphansi kwezembozo zamathambeka anezimila zokulawula ukuguguleka kanye nezinhlelo zokukhipha amanzi zokuvikela, lapho iqoqa futhi isuse imvula engenayo, igcina ingubo yomhlaba evikelayo ingagcwalisiwe futhi ingathambekeli ekusheleleni. Konke lokhu kufakwa kususa isidingo samanzi aminyene e-chimney drain, okwenza kube lula kakhulu ukwakha ngemuva kwezakhiwo eziqondile neziyimfihlo.

EzoLimo kanye nezinhlelo zokukhipha amanzi emhlabathini ziqedela iphothifoliyo, kanti i-geonet ifakwa ngaphansi kwezinkundla zemidlalo, izindawo zegalofu eziluhlaza, izingadi zezihlahla, kanye namasimu ezitshalo abiza kakhulu ukuze kukhishwe umswakama omningi emhlabathini ngaso leso sikhathi lapho wakheka khona. Kulezi zimo i-geonet ivamise ukulalwa phezu komhlaba wemvelo ongaphansi, ngaphansi kongqimba lwesihlabathi noma inhlabathi engeziwe, ukuze kubanjwe amanzi adonswa amandla adonsela phansi okungenzeka ukuthi agcwalise izindawo zezimpande zezitshalo futhi abangele izifo noma ukuphelelwa umoya kwezimpande. Amanethiwekhi afanayo okukhipha amanzi e-geospace asetshenziswa ngaphansi phansi kwezindlu zokugcina izitshalo, izinkundla zamahhashi, kanye nezindawo zokuhlotshiswa kwendawo lapho amanzi amile kanye nezindawo ezithambile zingamukeleki. Ukukhipha amanzi ngaphansi komhlaba nge-geonet futhi kusekela ukulungiswa kwenhlabathi ethintekile usawoti ngokugeza usawoti onqwabelene ngaphansi kwendawo yezimpande ngokunisela ngezikhathi ezithile, okuwuhlelo oludinga ukusebenza okuqhubekayo kwe-hydraulic iminyaka eminingi. Izimayini nazo zisebenzisa amandla amakhulu okukhipha amanzi e-geonet ngaphansi kwezindawo zokuhluza i-heap-leach kanye nezindawo zokugcina izinsalela ukuze ziqoqe izixazululo ezikhulelwe futhi zigcine ukuzinza. Kuzo zonke lezi zinhlelo zokusebenza, ukuqedwa kwezingqimba ezijiyile ze-granular filter kwenza i-drainage geonet ibe yisixazululo esikhangayo nomaphi lapho indawo, isisindo, noma ezomnotho zibalulekile kuphrojekthi.

Ukukhetha i-geonet efanele kuqala ngokuhlola ngokucophelela izidingo ze-hydraulic, kusukela ku-design flow rate okufanele ithwalwe i-drainage plane ngaphansi kwezimo ezithile zomthwalo kanye ne-gradient okulindelekile emsebenzini. Wonke umkhiqizo we-geonet ushicilela amajika e-transmissivity achaza amandla okugeleza njengomsebenzi we-applied normal stress kanye ne-hydraulic gradient, ukuze abaklami bakwazi ukuqhathanisa ukusebenza kwesikhathi saselabhorethri yomkhiqizo nokugeleza kwabo okubaliwe okuvela emvuleni, emanzini angaphansi komhlaba, noma ekukhiqizweni kwe-leachate. Ukumelana nokugcwala amandla kuyipharamitha yesibili ye-hydraulic okufanele inakwe, njengoba i-geonet efakwe endaweni enenhlabathi eningi noma enezinto eziphilayo ingalahlekelwa kancane kancane amandla okugeleza uma izinhlayiya zayo ezincane ziqoqeka phakathi kwenethiwekhi yemigudu; ukuhlanganisa umongo ne-nonwoven geotextile enosayizi wokuvuleka ofanele kubhekana naleyo ngcuphe. Ukuhambisana kwamakhemikhali ne-leachate noma i-chemistry yamanzi angaphansi komhlaba, kuhlanganise ne-pH extremes kanye nosawoti oncibilikisiwe, nakho kufanele kuqinisekiswe ngaphambi kwesicaciso, futhi emisebenzini esemhlabathini othambile kakhulu, umuntu kufanele futhi acele idatha yokugeleza yesikhathi eside kumkhiqizi ngemva kwe-creep deformation ende kanye nokufukamela kwezinto eziphilayo. Abakhiqizi abanolwazi bashicilela amaphepha edatha aphelele analezi zindinganiso zokusebenza, futhi abahlinzeki abathembekile abafana ne-Geofantex bakwenza kutholakale kalula konjiniyela abaklami abangase babe abathengi.

Ngaphandle kwe-hydraulics, onjiniyela kufanele bahlole izici zomshini ze-geonet ekhethiwe, ikakhulukazi amandla okudonsa, ukweluleka lapho iphuka, nokuziphatha kwe-compressive creep, konke lokhu okunomthelela ekufakweni nasekusebenzeni kwesikhathi eside kwempahla. Amandla okudonsa alawula ukuthi ingakanani amandla i-geonet engawabekezelela ngesikhathi sokufakwa, ukuboshwa, nokuhla komhlaba okulandelayo, futhi amandla aphezulu anconywa ezinhlelweni ezisemithambekeni ewukhekheba noma phezu kwezisekelo ezithambile kakhulu lapho ukusekelwa okulinganayo kungabikho. Izici zokweluleka zembula ukuthi ingakanani ukuguquka kwesimo i-geonet engakwamukela ngaphambi kokuphuka, okubalulekile ikakhulukazi kuma-landfill caps ahlala ngokwehlukana noma kuma-expansive soil profiles. Amandla okucindezela nokumelana ne-creep kunquma ukugcinwa kobukhulu nomthamo womgodi ngaphansi kwamashumi eminyaka ingcindezi ye-overburden eqhubekayo, ngakho ukukhetha i-resin eqinile ne-rib profile ewugqinsi kubalulekile ezinhlelweni zokungcwaba ezijulile. Lapho ukuhlunga nokuhlukanisa nakho kudingeka, osonkontileka ngokuvamile bacacisa i-geonet geocomposite (inhlanganisela eboshiwe noma e-needle-punched enama-nonwoven geotextiles), okwenza lula ukuhamba kwezimpahla futhi kuqinisekise ukusebenza kokuhlunga nokudonsa ngokufakwa okukodwa; i-I-Geocomposite1 uhla lwemikhiqizo ku-Geofantex lukhombisa indlela lezi zendlalelo ezihlanganiswa ngayo. Ekugcineni, usayizi wembobo kanye nohlobo lwe-polymer kufanele kuhambisane nezimo zendawo; i-HDPE inikeza ukumelana namakhemikhali okuphezulu, kuyilapho izinhlobo ze-PP zinikeza ukuguquguquka futhi kwesinye isikhathi izindleko eziphansi, futhi izimbobo ezinkulu zinikeza ukugeleza okuphezulu kuyilapho ezincane zimelana kangcono nokungena kwenhlabathi.

Ukufakwa okufanele kuyisici esisodwa esibaluleke kakhulu esinquma ukuthi i-geonet isebenza ngokugcwele ngokwesimo sayo esiklanyelwe, futhi le nqubo iqala ngokulungiselelwa kahle kwesizinda kanye nokuhlolwa kwesisekelo somgwaqo. Indawo lapho i-geonet izohlala khona kufanele icindezelwe ngokwesimiso, ibe bushelelezi ngokwanele, futhi ingabi namatshe abukhali, izimpande eziqhumayo, imfucumfucu yokwakha, kanye nezinye izinto eziqhumayo ezingagwaza umgogodla wokudonsa amanzi ngesikhathi sokugcwalisa. Ngaphambi kokuvula impahla, ofaka kufanele aqinisekise ukuthi umthambeka wesisekelo ugeleza uya ezindaweni zokuqoqa ezihlosiwe, ngoba i-geonet idlulisa amanzi kuphela uma inendawo yokuphuma kanye nomthambeka oqondile wokuhambisa ukugeleza. Noma yiziphi izindawo ezigobhozayo noma ezinamanzi amile esisekelweni kufanele zilungiswe ngaphambi kokufakwa kwe-geonet, ngoba amanzi amile abambeke ngaphansi kwengubo enza ukuthi isakhiwo sokudonsa amanzi singabi nasidingo. Kuyaphinde kube ukuhlakanipha ukuqinisekisa ukuthi amapayipi okudonsa amanzi aseduze noma imisele yokudonsa amanzi isendaweni efanele futhi ihlungiwe ukuze amanzi aphuma ku-geonet abe nendlela engavinjelwe eya ohlelweni lokuqoqa, nokuthi inani kanye nebanga lamaphoyinti okuphuma kuhlangabezana nezibalo zomklami zokugeleza kwamanzi.

Izidingo zokweqa nokuhlanganisa zenziwa ngokulandela isiqondiso somkhiqizi kanye nencazelo yephrojekthi, ngokweqa okuvamile kwe-geonet okusukela kumasentimitha ambalwa emaphethelweni emiqulu kuya kumanani amakhulu lapho kulindeleke ukwehla kwenhlabathi. Emiklameni eminingi, amaphaneli aseduze amane aweqwe nje kanti iphaneli ephezulu ilele phezu kwephansi, okuqinisekisa ukuthi amanzi ageleza esuka kwelinye iphaneli aye kwelilandelayo esikhundleni sokuhlangabezana nomphetho obheke emuva, futhi ngezinye izikhathi lokhu kweqa kuboshwa ngezibopho zekhebula noma izikhonkwane ukuvimbela ukusuka endaweni. Lapho kusetshenziswa i-geocomposite ene-geotextiles ehlanganiswe ngokushisa, izingxenye zendwangu yokuhlunga ezindaweni zokweqa kufanele nazo zihlanganiswe ukuze inhlabathi ingakwazi ukudlula endaweni yokuhlangana emngceleni we-geotextile. Ukuma kwe-geonet nakho kufanele kuhlonishwe; nakuba ukugeleza ngaphakathi kwephaneli kungafani nhlobo kwemikhiqizo eminingi, abaklami ngezinye izikhathi bafaka into ngokuthi i-eksisi ende yamaphaneli ihambe ngokuphambene nokugeleza okuyinhloko kokudonsa amanzi, futhi amaphaneli kufanele aboshwe emaphethelweni awo aphezulu emithambekeni ukuvimbela ukugingqika ngesikhathi sokufakwa kwenhlabathi yokugcwalisa. Okokugcina, ingaphansi kwanoma iyiphi i-geotextile yokuhlunga kufanele igcinwe ihlanzekile enhlabathini nasothulini ngesikhathi sokugoqa, ngoba ukungcola konakalisa ngokushesha umsebenzi wokuhlunga; ukuvikela imiphetho yephaneli ngezikhwama zesihlabathi noma izikhonkwane phakathi nomsebenzi kuvimbela ukuphakama komoya nokusuka endaweni ngengozi.

Ukugwema ukulimala ngesikhathi sokugcwalisa umgodi kuyisiyalo sokugcina esibalulekile, ngoba ngisho ukufakwa kwe-geonet okuphelele kungonakaliswa yimishini yokwakha enganaki ebeka izinto zokugcwalisa ezinzima ngqo phezu kwendawo eveziwe. Ukugcwalisa kwokuqala kufanele kube ungqimba oluncane lwesihlabathi esihlanzekile, esiyindilinga noma amatshe amancane, kubekwe nge-dozer noma umgubasi osebenza esuka ku-geonet eya ngaphandle kunokushayela ngqo phezu kwezinto. Yonke imishini yokwakha kufanele igcine isembozo esincane sokugcwalisa okuxegayo ngaphansi kwemikhondo noma amathayi ayo ngaphambi kokuhamba phezu kwe-geonet, futhi noma yimaphi amatshe abukhali noma ama-quarry spalls kufanele ahlukaniswe ekuxhumaneni okuqondile nomgogodla we-geonet kusetshenziswa isivikelo se-geotextile cushion. Imishini yokucindezela kufanele isebenze ngendlela engadali amandla e-shear noma ukulayisha okukhomba esakhiweni sokudonsa amanzi, kusetshenziswa izindlela zokudlidliza ngokucophelela ukugwema ukuxova izimbambo ze-geonet eceleni. Izisebenzi kufanele futhi zilungise noma yikuphi ukusikwa noma ukudabuka okwenzekile ngokushesha ngokubeka isiqeshana se-geonet efanayo noma i-geocomposite esikhula okungenani unyawo olulodwa ngale kwendawo eyonakele kuzo zonke izinhlangothi. Ukuhlolwa okujwayelekile ngummeleli womnikazi esigabeni ngasinye sokufakwa kuzobamba amaphutha kusenesikhathi, kuvimbele ukususwa okubizayo nokuphazamisayo kwezingqimba zokugcwalisa eziqediwe kamuva ekwakheni.

I-Geofantex Geosynthetics yakhe idumela layo njengomhlinzeki womhlaba wonke ohamba phambili ngokuhlanganisa ukuqinisekiswa kwekhwalithi okuqinile nokulethwa okuthembekile ngempela, okwenza imikhiqizo yayo ye-geonet ibe yisinqumo esithembekile konjiniyela bomphakathi, bezemvelo, kanye nabezimayini.

Izitifiketi zempahla eziqinisekisiwe kanye nezinhlelo zokugcinwa kwamasampula zinikeza amaklayenti ukulandelela okuphelele kusukela ku-resin eluhlaza kuze kufike kumkhiqizo ophelile, izinga lokusobala elibalulekile kumaphrojekthi okulahla udoti noma kahulumeni adinga imibhalo. Ngenxa yokuthi ifekthri ilawula uchungechunge oluphelele lokukhiqiza kusukela ku-resin engenayo kuze kufike ekupakishweni kweroli yokugcina, i-Geofantex ingaqinisekisa ukuthi ama-geonet ayo e-HDPE ne-PP awanazo izinto ezingcolile ezisetshenzisiwe futhi akhiqizwa ngokulingana kwejiyometri okungaguquguquki, okuletha osayizi bamafasitela abafanayo kanye nobukhulu bezimbambo kuzo zonke izingxenye. Amaklayenti omhlaba wonke avamise ukuqinisekisa lezi zindinganiso ngokuhlolwa kwelabhorethri yabantu besithathu kanye nokuvakasha ezindaweni, futhi inkampani iphendula ngemininingwane ephelele yokusebenza uma iceliwe.

Ukusebenza kahle kwezohwebo kokusebenzisana ne-Geofantex nakho kuyakhanga ngokulinganayo, ngosayizi abenziwe ngokwezifiso kanye nezikhathi zokuhola ezisheshayo ezijwayelekile kumaphrojekthi anoma yisiphi isikali. Lapho abakhiqizi abaningi bekhawulela amaklayenti ebangeni elincane lobukhulu bemibhobho yesitokhi, i-Geofantex izosika i-geonet ibe nobubanzi nobude obuhambisana nephrojekthi, kunciphise kakhulu imfucuza yasendaweni kanye nezidingo zokugqagqana kuyilapho futhi kwenza lula umsebenzi wokufaka odinga abasebenzi abaningi. Iqembu losekelo lobuchwepheshe langaphakathi lisiza ekukhetheni umkhiqizo, ezibalweni ze-hydraulic, nasekuxazululeni izinkinga zokufaka, lihola osonkontileka ngemininingwane yokugqagqana, ukubambelela emithambekeni, nokuxhunywa kwezindawo zokuphuma ze-geonet ezinhlelweni zokuqoqa amapayipi; ithimba futhi lijabulela ukuphendula imibuzo mayelanaI-HDPE Geomembrane ukuhambisana, Izinto Zokulawula Ubumba ze-Geosynthetics, kanye nezinye izingqimba ze-liner ezisetshenziswa ohlelweni olufanayo. Isiqondiso sabo sisekelwe eminyakeni engamashumi eminingi yolwazi lwamaphrojekthi emigwaqweni, ezindaweni zokulahlwa kwemfucuza eqinile, emisebenzini yezimayini, kanye nokudonswa kwamanzi kwezolimo, ngakho-ke amaklayenti athola okungaphezu nje kwe-oda lokuthenga nokuthunyelwa kwempahla. Intengo yasefektri eqhudelanayo, ngaleso sikhathi, izuzisa kokubili osonkontileka abakhulu bengqalasizinda abathenga ngenqwaba kanye namaphrojekthi amancane akhethekile acela ama-roll ambalwa kuphela, namathimba ezokuthutha ecaphuna imali yokuthutha evumayo kuyo yonke imikhumbi emikhulu emhlabeni. Ukuze kutholakale ukuzethemba okwengeziwe, amaklayenti angaba yiklayenti angabuyekeza amakhono esikhungo kanye nomlando wenkampani ku-MAYELANA NATHI ikhasi futhi ubone ukuthi ikhwalithi yakwa-Geofantex isetshenziswa kanjani emndenini womkhiqizo obanzi, okuhlanganisa I-Geogrid ukuqinisa kanye I-Geocell izinhlelo zokuzinza ezivame ukuhlotshaniswa nezingqimba zokudonsa amanzi ze-geonet.

Ngaphandle kwempahla ngokwayo, ukukhetha i-Geofantex kusho ukuthola umlingani wobunjiniyela oziphendulayo ozokuma ngemuva komkhiqizo phakathi nomjikelezo wonke wokwakha nangale kwawo. Inkampani ikhuthaza amaklayenti ukuthi acele amasampula angaphambi kokuthunyelwa ukuze azihlolele wona, futhi yamukela isitifiketi somuntu wesithathu senqubo yayo yokukhiqiza, okubonisa indlela ebeka iklayenti phambili abancintisani abakhulu bakahulumeni abangavamile ukuyilandela. Wonke umklamo, kusukela ekulungiseni udonga olubambayo oluncane kuya esigabeni sokulahla imfucuza esingamamitha-skwele ayisigidi, uthola ukunakwa okufanayo okuqinile ekuhambisaneni nencazelo, ukupakisha okuvikela imiqulu ngesikhathi sokuthutha olwandle, kanye namadokhumenti okulethwa avula amasiko ngaphandle kokubambezeleka. Kubonjiniyela nosonkontileka ababhekana nezabelomali lapho yonke into ibalulekile, imodeli yasefektri ngqo ye-Geofantex isusa inzuzo yomhambisi esibalweni sentengo, ikhiqize ukonga kwangempela kwezindleko ngaphandle kokuyekethisa ikhwalithi ye-resin noma ukunemba kokukhiqiza. I-Geofantex izibeka njengomhlinzeki wezisombululo okhathalela umphumela wokufakwa ngakunye kwamanzi, hhayi nje inani ledola lomyalo, futhi uhlu lwayo olude lwamaklayenti aphindayo emikhakheni yemigwaqo, ukugcinwa kwamanzi, izimayini, kanye nokuvimbela ukungcola kukhuluma ngalokho kuzibophezela. Khuluma neqembu labo lobuchwepheshe ekuqaleni kwenqubo yakho yokuklama, futhi ochwepheshe babo bazocacisa izidingo zokugeleza, baqhathanise izakhiwo ze-geonet ezitholakalayo, futhi bancomise incazelo engabizi kakhulu yezimo zendawo yakho ezithile.

Ama-geonet geosynthetics ashintshe indlela onjiniyela abaphatha ngayo amanzi ngaphansi komhlaba, ehlinzeka ngokusebenza kokudonsa amanzi, ukuhlunga, nokuhlukanisa okwakungenakufezeka ngezinhlelo ezijwayelekile zezinto eziyimbudumbudu emashumini ambalwa eminyaka edlule. Izinzuzo zobuchwepheshe ezizakhela phakathi—amandla okudonsa amanzi angaphezulu kakhulu, ukumelana nokugxotshwa ngaphansi kokugqitshwa okujulile, ukuqina kwamakhemikhali kwe-HDPE ne-PP resins, kanye nokuncipha okukhulu kwesikhathi nezindleko zokwakha—kuyenza ibe yincazelo ezimisiwe yemigwaqo yesimanje, ukususwa kwe-landfill leachate nokuqoqwa kwegesi, ukudonsa amanzi emithambekeni, izinhlelo zokulawula ukuguguleka komhlaba, kanye nokuphathwa kwamanzi kwezolimo. Ukukhetha i-geonet efanele kudinga ukuhlaziywa ngokucophelela kwezidingo zokugeleza, amandla okugcwala isikhathi eside, izici zokudonsa nokukhasa, bese kuqhathaniswa nalezi nosayizi wamafasitela nezinhlobo ze-polymer ezinikezwa umkhiqizi othembekile. Ukufakwa okuhle kuyaphelelisa uchungechunge: ukulungiselela kahle kwesisekelo, ukubekwa okuhlelekile kokugqagqana nokuqondiswa kokudonsa amanzi, kanye nezinqubo zokugcwalisa ngomhlabathi ezivikelayo konke kugcina umsebenzi wamanzi owakhelwe isikhathi sokuphila kwempahla. I-Geofantex Geosynthetics isendaweni enhle yokuhlinzeka ngezinto ze-geonet, ama-geonet geocomposites, kanye namaphakethe aphelele okudonsa amanzi anezitifiketi zekhwalithi, ubukhulu obenziwe ngokwezifiso, ukugcwaliseka okusheshayo, kanye nokusekelwa kobuchwepheshe okusebenzayo okudingwa amaphrojekthi anoma yisiphi isikali. Ukuze uqhubeke phambili, xhumana neqembu le-Geofantex nge-Xhumana nathi ikhasi ukuze ucele isilinganiso esisemthethweni noma uhlele ukubonisana kwezobuchwepheshe; kungenjalo, eminye imininingwane yomkhiqizo kanye nezifundo zezimo zobunjiniyela zingatholakala nge- I-Drainage Geonet1 ikhasi lomkhiqizo nezinsiza eziwusizo ku- Ibhulogi ikhasi lasekhaya. Ukunikeza idatha yabo yokuklama, ulwazi lwe-gradation, kanye nempilo yesevisi elindelekile kuzovumela onjiniyela bakwa-Geofantex ukuthi bakhe iphakethe le-geonet elivikela ingqalasizinda yakho amashumi eminyaka kuyilapho liletha ukonga okulinganisekayo kuzo zombili izindleko nesikhathi sokwakha.
