Ama-geogrids asephenduke ingxenye ebalulekile emsebenzini wanamuhla wobunjiniyela bomphakathi, enikeza ukuqiniswa okubalulekile kwezakhiwo zomhlabathi, izindonga zokugcina, imithambeka, nemigwaqo. Nokho, impumelelo yanoma yimuphi umsebenzi we-geogrid ayincikile nje kuphela ekhwalithini yezinto ezisetshenziswayo kodwa ekuqineni kokufakwa kwayo. Ngisho ne-geogrid yezinga eliphezulu kakhulu ngeke isebenze kahle uma izinqubo ezinhle zokufaka zingalandelwa, okuholela ekwehlulekeni okubizayo nasekulimaleni kobuqotho besakhiwo. Konjiniyela nosonkontileka abasebenza nezixazululo ezivela ku-Geofantex Geosynthetics, ukuqonda lezi zinkinga ezivamile nezixazululo zazo kubalulekile ekuphileni isikhathi eside kwephrojekthi. Lo mhlahlandlela obanzi uhlola izinselele ezivame kakhulu zokufaka i-geogrid ezitholakala ezindaweni zokwakha futhi unikeza izixazululo ezisebenzayo zokunqoba lezi zinselele. Kusukela ekulungiseleleni i-subgrade kuya ezindleleni zokubamba, isigaba ngasinye sidinga ukunaka okucophelelayo kwemininingwane. Ekupheleni kwalesi sihloko, uzobe usunolwazi oludingekayo ukuze uqinisekise ukuthi iphrojekthi yakho elandelayo izuza ekusebenzeni okuphezulu kokuqiniswa. Imininingwane eyabiwe lapha isuselwa ezindinganisweni zemboni kanye nezinzuzo ezithile zobunjiniyela ezinikezwa imikhiqizo ye-Geofantex.

Enye yamaphutha avame kakhulu ngesikhathi sokufakwa kwe-geogrid ukunganaki ukulungiswa kahle kwesisekelo somhlabathi (subgrade). Isisekelo somhlabathi kufanele silungiswe kahle, sicindezelwe, futhi singabi namatshe amakhulu, imfucumfucu, noma izinto eziphilayo ezingabangela ukusabalalisa kwengcindezi okungalingani. Lapho kufakwa i-geogrid yokwakhiwa komgwaqo, osonkontileka kwesinye isikhathi bacabanga ukuthi umhlabathi okhona wanele, kodwa kamuva bathola ukuthi izindawo ezithambile noma ukugoba kuholele ekuhlukaniseni kokugcina (differential settlement) nokuqhekeka komgwaqo. Uphenyo olufanele lwesiza kufanele luhlanganise ukuhlukaniswa komhlabathi, ukuhlolwa komswakama, nokuhlolwa kokucindezela ukuze kutholakale izimo eziyisisekelo. Isisekelo somhlabathi kufanele sihlolwe ngokugoqwa (proof-rolled) ukuze kutholakale izindawo ezibuthakathaka ezifihlekile ezidinga umsebenzi wokulungisa noma ukuqiniswa okwengeziwe. Ezinhlelweni zokuqiniswa komhlabathi, amandla okuthwala isisekelo kufanele aqinisekiswe ukuze kugwenywe ukungazinzi okuphelele. I-Geofantex incoma ubuncane bokujula kokulungiswa kwesisekelo esingama-150 mm, ngokucindezela okungenani okungama-95% wokuminyana okujwayelekile kwe-Proctor. Ukukhipha amanzi kungenye into ebalulekile okufanele icatshangwe — amanzi ami angathambisa isisekelo futhi anciphise ukuxhumana kokungqubuzana phakathi komhlabathi ne-geogrid. Uma kukhona amanzi angaphansi komhlabathi, kufanele kufakwe ungqimba lokukhipha amanzi olusemaceleni noma uhlelo lwe-geocomposite lokukhipha amanzi ngaphansi kwendawo yokuqinisa. Ngaphandle kwalezi zinyathelo zokulungiselela, ngisho ne-geogrid ye-polyester eqine kakhulu izohluleka ukusebenza ngendlela ehlosiwe, futhi sonke isakhiwo singaba sengozini yokwehluleka ngaphambi kwesikhathi. Khumbula ukuthi i-geogrid isebenza ngokuphumelela kuphela ngokuya ngesisekelo esiyiphethe, ngakho ukutshala isikhathi ekulungiseni isisekelo somhlabathi kuletha inzuzo enkulu kuso sonke isikhathi sokuphila kwephrojekthi.

Ukungahambisani nokufinyaniswa okunganele yizinkinga ezivamile eziphazamisa indlela yokudlulisa umthwalo kuma-geogrid. Uma i-geogrid ingahambisani nomkhombandlela oyinhloko wokucindezeleka, amandla ayo okudonsa awasetshenziswa ngokugcwele, okuholela ekuqiniseni okungasebenzi kahle nokunokwenzeka kokuguquka kwesimo. Ngesikhathi sokufakwa, imiqulu ye-geogrid kufanele ibekwe ukuze umkhombandlela oyinhloko wokuqinisa uhambisane namandla okudonsa alindelekile — ngokuvamile uqondane nobuso bodonga olugodlayo noma ulandele umugqa omude womgwaqo. Emaphrojekthini abandakanya ama-geogrid e-Geofantex PP biaxial, ukuma okufanele kubaluleke nakakhulu ngoba impahla inikeza amandla alinganayo kuyo yomibili imikhombandlela yomshini nokunqamulayo, kodwa kuphela uma ibekwe kahle. Ukufinyanisa kubaluleke ngokulinganayo; i-geogrid engafinyaniswanga ayikwazi ukukhiqiza ukucindezeleka kokudonsa okudingekayo kuze kube yilapho kusenzeka ukunwebeka okukhulu, okushaya phansi inhloso yokuqinisa kusenesikhathi. Osonkontileka kufanele basebenzise ukufinyanisa ngezandla noma ngensimbi yokufinyanisa, basuse imibimbi futhi baqinisekise ukuthi i-geogrid ilele ngokuyisicaba phezu komhlabathi ongaphansi. I-Geofantex incoma amandla okufinyanisa afinyelela ku-1–2% wokunwebeka ku-geogrid, okuqinisekiswa ngokuqondisa okubonakalayo kwezimbambo. Inqubo yokufaka i-geogrid ngokufinyaniswa okufanele iphinde ivimbele ukwakheka kwamagagasi noma ukugoqeka okudala izikhala ekugcwalisweni okungaphezulu. Emithambekeni nasezindongeni eziwumqansa, ukufakwa kwezikhonkwane zesikhashana ngezikhathi ezihlukaniswe ngamamitha 1.0 kuya ku-1.5 kusiza ukugcina ukufinyanisa ngenkathi kufakwa umhlabathi wokugcwalisa. Uma ukufinyanisa kunganakwa, inhlabathi eqinisiwe ingase ibhekane nokuguquka okweqile komzimba ngaphansi komthwalo, okuholela ekwehlulekeni kokusebenza kahle.

Enye inselele ebalulekile ngesikhathi sokufakwa kwe-geogrid ukuphatha ukuhlangana nokuhlanganiswa phakathi kwamaroli asondelene. Lapho iphrojekthi idinga ukuqiniswa okuqhubekayo endaweni ebanzi, amajoyinti aba amaphuzu abuthaka uma engaklanywa kahle futhi enziwe kahle. Ibanga lokuhlangana elidingekayo lincike emandleni okudonsa kwento, ubukhulu bemithwalo esetshenziswayo, kanye nezimo zengaphansi komhlaba. Ezinhlelweni ezijwayelekile zomgwaqo nomgwaqo ezingaphansi eziqinile, ukuhlangana okuncane okungu-300 mm kuyindinganiso, kuyilapho izindawo ezingaphansi ezithambile zingadinga ukuhlangana okufika ku-600 mm noma ngaphezulu. Imikhiqizo ye-GEOFANTEX polyester geogrid, eyaziwa nge-modulus yayo ephezulu nokukhasa okuphansi, isebenza kahle kakhulu lapho ukuhlangana kubekwe ezindaweni ezinengcindezi ephansi, kude nezindawo ezibucayi ezingaphansi kwamasondo noma imithwalo yesakhiwo. Ukuhlanganiswa ngomshini kusetshenziswa izikhonkwane, izikhonkwane, noma izixhumi ezikhethekile kuyanconywa lapho idizayini idinga ukudluliswa okugcwele komthwalo kulo lonke ijoyinti, ngoba ukuhlangana nje okulula kungenzeka kungathuthukisi amandla aphelele okudonsa. Kubalulekile ukulandela imihlahlandlela yomkhiqizi yokuhlanganisa ngokucacile — i-GEOFANTEX ihlinzeka ngamatafula anemininingwane yokuhlangana nedatha yamandla okuxhumana kuhlobo ngalunye lwe-geogrid yayo. Ukuqondiswa kokuhlangana nakho kubalulekile; i-roll ekhuphuka ihla yonke indlela kufanele ihlangane ne-roll ehla emthambekeni ukuze amandla adluliselwe ngaphandle kokuphakamisa ijoyinti. Uma ukuhlanganiswa kwenziwa ngokungalungile, ungqimba lokuqinisa lusebenza njengamashidi ahlukene, angaxhunyiwe, futhi umhlabathi ungahlukana ejoyintini, okuholela ekwehlulekeni kwendawo ethile. Ukuhlela ngokucophelela ukwakheka kwe-roll ngaphambi kokufakwa kunciphisa inani lokuhlanganiswa futhi kuqinisekisa ukuthi kubekwe ezindaweni ezingabalulekile kakhulu.

Ama-geogrid ngokuvamile enziwa ngezinto zepholima ezifana ne-polypropylene noma i-polyester, okuthi, nakuba aqinile ekuqineni, angaba sengozini yokubhobozwa nokusikwa izinto ezicijile ezisemgwaqweni ongaphansi noma ekugcwalisweni. Amadwala acijile, izingcezu zikakhonkolo eziphukile, ngisho namathuluzi okwakha angaklwebha noma asike izimbambo ngazinye, kunciphisa indawo enqamulelayo futhi kwenze buthaka ukuqiniswa kukonke. Ngesikhathi sokufakwa, abasebenzi bangahamba ngqo phezu kwe-geogrid namabhuzu anetshe elingaphakathi, okudala umonakalo omncane oqongelelwa ngokuhamba kwesikhathi. Ukunciphisa lezi zingozi, i-Gefantex incoma ukusetshenziswa kongqimba oluvikelayo lwesihlabathi noma i-fine aggregate — ngokuvamile ubukhulu obungu-50 kuya ku-100 mm — olubekwa ngaphansi nangaphezulu kwe-geogrid. Lolu ngqimba lokugudluza luhlukanisa i-geogrid ezinhlayiyeni eziyizingodo futhi lusabalalisa imithwalo yamaphoyinti ngokulinganayo. Uma isabelomali sephrojekthi noma isheduli ingavumeli ungqimba oluhlukile lokuvikela, ukukhetha i-geogrid enesisindo esinzima enezimbambo eziwugqinsi kunganikeza ukumelana nokubhobozwa okungokwemvelo. Isibonelo, ama-geogrid e-Geofantex PP biaxial atholakala ngamazinga amaningi okudonsa, okuvumela onjiniyela ukuthi bakhethe inketho eqinile ezimweni ezinzima zendawo. Ukuhlolwa okuvamile okubonakalayo ngesikhathi sokugcwaliswa kubalulekile; noma yiziphi izingxenye ezilimele kufanele zisikwe futhi zifakwe isiqephu esingqamuzanayo sohlobo olufanayo lwe-geogrid, esinwebela okungenani u-300 mm ngale kwendawo elimele kuzo zonke izinhlangothi. Ukuhamba kwemishini ngqo phezu kwe-geogrid eveziwe kungenye imbangela enkulu yokubhobozwa — izimoto zokwakha akufanele neze zishayele phezu kwe-geogrid engavikelwe, futhi kufanele kugcinwe ukumbozwa okuncane okungu-150 mm ngaphambi kokuvumela noma yiziphi izimoto ezinamasondo. Ngokubhekana nezingozi zokubhobozwa ngokuqhubekayo, osonkontileka balondoloza amandla aphelele e-geogrid futhi bagweme ukukhubazeka okucashile okungabeka engcupheni iphrojekthi eqediwe.

Ukubambelela kwama-geogrid emaphethelweni ezindawo eziqinisiwe kubalulekile ekuthuthukiseni amandla okudonsa nokuvimbela ukwehluleka kokukhishwa. Ezinsizeni zodonga lokugcina umhlabathi nethambeka eliwumqansa, ubude bokubambelela obunganele emsileni wokuqinisa kuyiphutha elivamile elingaholela ekuweni okuyinhlekelele. Ubude bokufakwa obudingekayo buncike kumfutho womhlabathi ongenhla, amandla okushelela komhlabathi, kanye ne-coefficient yokungqubuzana phakathi kwe-geogrid nomhlabathi. Emgwaqweni ojwayelekile we-granular backfill, i-GEOFANTEX incoma ubude bokubambelela obuncane obungu-1.0 mitha ngemuva kwendiza yokwehluleka engaba khona, kuqinisekiswe ngokuhlolwa kokukhishwa kwe-pullout endaweni ethile lapho izimo zephrojekthi zibucayi. Izinqubo zokubeka nokucindezela umhlabathi wokugcwalisa zibalulekile ngokufanayo — umhlabathi kufanele ubekwe ngezingqimba ezixekethile ezingama-150 kuya ku-200 mm futhi ucindezelwe ekuqineni okucacisiwe ngaphambi kokuba kufakwe ungqimba olulandelayo. Imishini yokucindezela esindayo akufanele isondele ngaphansi kwamamitha angu-0.5 ubuso bodonga noma onqenqemeni lwethambeka ukuze kugwenywe ukususwa kwe-geogrid. Ukucindezela ngokweqile ngqo phezu kwe-geogrid kungadala ukulimala kwezimbambo nokunwebeka kwangaphambi kwesikhathi, kuyilapho ukucindezela okungaphelele kushiya izikhala ezivumela ukunyakaza komhlabathi. I-GEOFANTEX ihlinzeka ngamashidi obuchwepheshe acacisa amandla aphezulu avunyelwe okucindezela kuhlobo ngalunye lwe-geogrid, iqinisekisa ukuthi osonkontileka bangafinyelela izinhloso zokuqina ngaphandle kokulimaza ukuqinisa. Umhlabathi wokugcwalisa ngokwawo kufanele ube nezinhlanganisela ezinhle, ukhiphe amanzi kalula, futhi ungabi nezinhlayiya ezinkulu kuno-50 mm ukuze kugwenywe ukugxila kwengcindezi endaweni ethile. Emhlabathini onamathelayo, izinhlinzeko zokukhipha amanzi ezifana nongqimba lwe-geocomposite drainage ngemuva kobuso bodonga ziyadingeka ukuze kuvinjelwe ukwakheka kwengcindezi ye-hydrostatic engadudula i-geogrid iye ngaphandle. Ukubambelela okufanele nezinqubo eziqinisekisiwe zokugcwalisa kuguqula i-geogrid isuka eshidini elilula ibe yinto ehlanganisiwe ethwala umthwalo ngaphakathi kwesakhiwo somhlabathi oqinisiwe, inikeze uzinzo lwesikhathi eside ngisho nangaphansi kwemithwalo yokuzamazama komhlaba neye-hydraulic.

Yonke indawo yokwakha iveza isimo sehlabathi esihlukile, izidingo zomthwalo, kanye nezici zemvelo, okwenza izixazululo ze-geogrid ezifanayo zinganele emisebenzini eyinkimbinkimbi. I-Geofantex Geosynthetics ibhekana nalesi nselelo ngokunikeza uhlu oluhlukahlukene lwemikhiqizo ye-geogrid eklanyelwe izinhlelo ezithile, okuhlanganisa ama-PP biaxial geogrids, ama-polyester geogrids, kanye nezinhlobo ezikhethekile zokuqinisa umhlabathi nokulawula ukuguguleka komhlabathi. Emisebenzini ebandakanya i-geogrid yokwakhiwa kwemigwaqo ezindaweni ezinomhlabathi othambile, ama-PP biaxial geogrids akwa-Geofantex anikeza amandla e-isotropic tensile asakaza imithwalo yezimoto endaweni ebanzi, anciphisa ukuguguleka kwemigwaqo futhi andise impilo yomgwaqo. Ezindaweni zezindonga zokugcina umhlabathi kanye nemithambeka emikhulu lapho kulindeleke imithwalo ephezulu eqhubekayo, ama-polyester geogrids akwa-Geofantex anikeza ukumelana nokunwebeka okukhethekile kanye namandla edizayini yesikhathi eside, aqinisekisa ukusebenza okuthembekile iminyaka eminingi. Inkampani futhi inikeza ububanzi nobude be-roll obungokwezifiso ukuze kuncishiswe ukumosheka kanye nokunciphisa inani lokuhlanganiswa endaweni, ibhekane ngqo nezinselelo zokugqagqana nokulinganisa okukhulunywe ngazo ngaphambilini. Wonke umkhiqizo we-geogrid wakwa-Geofantex udlula ukuhlolwa okuqinile kokulawula ikhwalithi, okuhlanganisa ukuqinisekiswa kwamandla e-tensile, ukuhlolwa kokusebenza kahle kokuhlanganisa, kanye nokuhlolwa kokuqina ngaphansi kokuchayeka elangeni nasezindaweni ezinamakhemikhali. Usizo lobunjiniyela luyatholakala ukusiza osonkontileka ekukhetheni uhlobo lwe-geogrid olufanele kanye nezinga elisezingeni elifanele ngokusekelwe kuzingqimba ezithile zendawo ezifana ne-pH yomhlabathi, amakhemikhali amanzi angaphansi komhlabathi, kanye nempilo yedizayini. Ngokusebenzisa amandla okwenza ngokwezifiso kwa-Geofantex, amaqembu omsebenzi angathuthukisa kokubili ukusebenza nezindleko, agweme izingibe zokusebenzisa izinto ezijwayelekile ezingaklanyelwe kahle (ezingabangela ukwehluleka) noma eziklanyelwe ngokweqile (ezimoshayo isabelomali). Ngezidingo ezikhethekile, i-Geofantex ingakwazi nokukhiqiza ama-geogrids ngosayizi wokuvula noma ubunjiniyela be-rib obuklanyelwe ukuthuthukisa ukuhlangana nezinhlanganisela ezithile zamatshe, kukhuliswe ukusebenza okuhlangene phakathi komhlabathi nokuqiniswa.

Ukufakwa kwe-geogrid okuyimpumelelo kudinga ukuqonda okuphelele kwe-mechanics yenhlabathi, izici zezinto, kanye nezinqubo zokwakha ezithile zendawo. Izinselelo ezidingidwa kulesi sihloko — kusukela ekulungiseni isisekelo nokuqondanisa kuya ekwakhiweni kokugqagqana, ukuvimbela ukubhoboza, nokufaka amatshe — zonke ziyalawuleka ngokuhlela ngokucophelela nokulandela izindlela eziqinisekisiwe. I-Geofantex Ama-Geosyntheticsisekela imboni hhayi nje ngemikhiqizo yegridi yomhlaba esezingeni eliphezulu kodwa futhi ngobuchwepheshe obudingekayo ukuze kuqinisekiswe ukufakwa okulungile. Ngokukhetha uhlobo olufanele lwe-geogrid kusetshenziswa ngalunye futhi kulandele izinqubo zokufaka ezinconyiwe, osonkontileka bangathola ukuqiniswa kwenhlabathi okuqhubekayo nokonga izindleko okumelana nesikhathi. Noma ngabe uqinisa umgwaqo, wakha udonga lokugcina, noma uqinisa ithambeka, izimiso ezishiwo lapha zizokusiza ugweme amaphutha avamile futhi ulethe iphrojekthi ehlangabezana noma edlula okulindelekile ekwakhiweni.
