I-Geotechnical mat yokuvimbela ukugeleza kwesiteshi nokukhipha amanzi
Isingeniso Somkhiqizo:
I-Geo textile mat iwuhlobo olusha lwe-geo synthetic material eyenziwe nge-mesh ehlanganisiwe futhi ebekiwe yemicu engahlelekile.Inokumelana nokucindezela okuphezulu, ukuminyana okuphezulu kokuvuleka futhi ineqoqo lamanzi eliyindilinga kanye nemisebenzi yokukhipha amanzi evundlile.Isakhiwo siwumgogodla we-geo we-geo enezinhlangothi ezintathu ezinezindwangu ze-geo ezingalukiwe ezinezimbobo emaceleni omabili.I-geo mesh core enezinhlangothi ezintathu idonsa amanzi angaphansi komhlaba ngokushesha futhi inohlelo lwayo lokulungisa izimbotshana, oluvimba amanzi e-capillary ngaphansi kwemithwalo ephezulu.Isebenza futhi njengokuqinisa isithiyo.
Izici Zomkhiqizo:
1. Ukumelana nokucindezela okuphezulu, ukuminyana kwemigodi ephezulu evulekile, nokuqoqwa kwamanzi okuyindilinga kanye nomsebenzi wokudonsa amanzi ovundlile.
2. Ngemuva kokuthi i-geotextile mat ihlanganiswe ne-geotextile engeyona eyelukiwe, ingaqoqa amanzi emvula angena ngongqimba lwesembozo senhlabathi noma indle ekhishwa egcekeni ngokwalo ngaphansi koqweqwe lwekhava evaliwe, futhi isebenzise umsebenzi wayo oyingqayizivele wokudonsa amanzi ukukhipha i-geotextile mat sandwich layer ngendlela ehlelekile ngokwezidingo zobunjiniyela, ngaphandle kokwenza udaka.Ngakho-ke, ingagwema inkinga yokushelela okungenzeka ngenxa yokumuncwa kwamanzi kongqimba lwekhava yenhlabathi.
3. I-Geomat mat ayikwazi nje ukukhipha amanzi, kodwa futhi ikhiphe igesi ye-methane ekhiqizwa ukuvutshelwa emhlabathini (ikakhulukazi imfucuza yemfucuza), efanelekile ngokukhethekile ukusetshenziswa endaweni yokulahla.
4. I-geotechnical mat kanye nesicelo esihlanganisiwe se-HDPE, ngesikhathi esifanayo singadlala indima enhle ekuvikeleni ulwelwesi lwe-HDPE ekubhobhozweni.
Ukucaciswa:

Isicelo:
Isetshenziswa kakhulu ekuvimbeleni ukugeleza kwesiteshi kanye nokukhipha amanzi, ukugeleza komzila wesitimela nothelawayeka, ukuhlehla kokuhlunga kokugcina.
izindonga, ukugeleza kwamanzi kanye nokuvimbela umswakama wezakhiwo ezingaphansi komhlaba, izindawo zokuhlanza indle, izindawo zokulahla imfucumfucu kanye namanye amaphrojekthi.
