I-Geotechnical mat yokuvimbela ukugeleza kwesiteshi kanye 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 ezinezimbobo ezingalukiwe eziboshiwe nhlangothi zombili. 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 njengesivimbelo sokuqiniswa.
Izici Zomkhiqizo:
1. Ukumelana nokucindezela okuphezulu, ukuminyana kwemigodi evulekile ephezulu, nokuqoqwa kwamanzi okuyindilinga kanye nomsebenzi wokudonsa amanzi ovundlile.
2. Ngemuva kokuthi i-geotextile mat ihlanganiswe ne-geotextile engalukiwe, ingaqoqa amanzi emvula angena ngongqimba lwesembozo senhlabathi noma indle ekhishwa egcekeni ngokwalo ngaphansi koqweqwe lwekhava evaliwe, futhi isebenzise umsebenzi wayo oyingqayizivele wokudonsa amanzi ukuze ikhiphe 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 ukudonsa amanzi kuphela, kodwa futhi ikhiphe igesi ye-methane ekhiqizwa ukuvutshelwa emhlabathini (ikakhulukazi imfucuza yemfucuza), efanelekile ngokukhethekile ekusetshenzisweni kwe-landfill.
4. I-geotechnical mat kanye ne-HDPE ehlanganisiwe yohlelo lokusebenza, ngesikhathi esifanayo ingadlala indima enhle ekuvikeleni ulwelwesi lwe-HDPE ekubhobhozweni.
Ukucaciswa:

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