Emsebenzini wokwakha wobunjiniyela, sifinyeze izici zokwakha zama-geogrid:
1. Indawo yokwakha ye-geogrid: Kudingeka ukuthi ihlanganiswe futhi ibekwe ileveli, ngendlela evundlile, futhi isuse izinto ezicijile neziphumela ngaphandle.
2. Ukwendlaleka kwe-geogrid: Endaweni eyisicaba futhi ehlangene, indlela yokucindezeleka eyinhloko (longitudinal) ye-geogrid efakiwe kufanele ibe yi-perpendicular eya e-eksisi yomugqa, futhi ukubeka kufanele kube isicaba, kungabi nemibimbi, futhi kufanele kuqinise kangangoba kungenzeka.Kulungiswe ngokufaka nokucindezela umhlaba netshe, isiqondiso esiyinhloko sokucindezeleka kwegridi ebekiwe kungcono ubude obugcwele ngaphandle kwamalunga, futhi ukuxhumana phakathi kobubanzi kungaboshwa ngesandla futhi kudlulele, ububanzi obudlulayo bungabi ngaphansi kuka-10cm.Uma igridi ifakwe izingqimba ezingaphezu kwezimbili, amalunga phakathi kwezingqimba kufanele anyakaze.Ngemuva kwendawo enkulu yokufakwa okuncane, ukuqina kwayo kufanele kulungiswe ngokuphelele.Ngemva kokumboza ungqimba lwenhlabathi nangaphambi kokugingqika, igridi kufanele iphinde igxiliswe ngamandla abantu noma imishini, ngamandla afanayo, ukuze igridi ibe sesimweni sokucindezeleka esiqondile emhlabathini.
3. Ukukhethwa kokugcwalisa ngemva kokufaka i-geogrid: Isigcwalisi sizokhethwa ngokuvumelana nezidingo zokuklama.Ukuzijwayeza kufakazele ukuthi yonke inhlabathi eqandisiwe, inhlabathi yexhaphozi, udoti wasendlini, inhlabathi kashoki, kanye ne-diatomite ingasetshenziswa njengezigcwalisi.Kodwa-ke, inhlabathi ewubhuqu kanye nenhlabathi yesihlabathi inezakhiwo ezizinzile zemishini futhi ithintwa kancane ngokuqukethwe kwamanzi, ngakho-ke kufanele ikhethwe.Usayizi wezinhlayiyana zokugcwalisa akumele ube mkhulu kuno-15cm, futhi ukunaka kuzokhokhwa ekulawuleni ukugreda kwesigcwalisi ukuze kuqinisekiswe isisindo sokuhlanganisa.
4. Ukugandaywa nokuminyanisa kwezihluthulelo zokhiye ngemva kokuqedwa kwe-geogrid: Uma i-geogrid ibekwa futhi ibekwe endaweni efanele, kufanele igcwaliswe futhi imbozwe ngesikhathi esifanele.Isikhathi sokuchayeka akufanele sidlule amahora angama-48.Ngaphandle kwalokho, indlela yenqubo yokugeleza yokugcwalisa ngemuva ngenkathi ubeka ingamukelwa.Gcoba isigcwalisi kuzo zombili iziphetho kuqala, lungisa igridi, bese uqhubekela phambili uye maphakathi.Ukulandelana okugoqayo kusuka ezinhlangothini zombili kuya phakathi.Ngesikhathi sokugoqa, i-roller ayimelani nokuxhumana okuqondile nezinto zokuqinisa, futhi izimoto ngokuvamile azivunyelwe ukushayela emizimbeni yokuqinisa engahlanganisiwe ukuze kugwenywe ukukhishwa kwezinto zokuqinisa.I-degree compaction degree ingu-20-30cm.Ukuminyanisa kufanele kuhlangabezane nezidingo zokuklama, okuphinde kube yisihluthulelo sempumelelo yobunjiniyela bomhlaba obuqinisiwe.
5. Izinyathelo zokugcina zokwelashwa zokuvimbela nokukhipha amanzi: Ebunjiniyela benhlabathi obuqinisiwe, kuyadingeka ukwenza umsebenzi omuhle wokuhlanza amanzi ngaphakathi nangaphandle kodonga;Vikela izinyawo zakho futhi uvimbele ukuguguleka.Izihlungi kanye nezinyathelo zokudonsa amanzi kufanele zihlinzekwe ngobuningi benhlabathi, futhi uma kunesidingo, amapayipi e-geotextile kanye namapayipi avuzayo (noma imisele eyimpumputhe) izohlinzekwa.Ukuthuthwa kwamanzi kuzoqhutshwa ngokudonsa, ngaphandle kokuvinjelwa, ngaphandle kwalokho izingozi ezifihliwe zingase ziphakame.
