Izinyathelo zokuqapha ukwakhiwa nokufakwa kwama-geomembranes kumachibi ama-tailings

Izindaba

Ukusika nokuthutha: Ngokusekelwe kumarekhodi okulinganisa wendawo yokubeka, rekhoda inombolo yenqwaba ye-geomembrane esikiwe bese uyihambisa endaweni yokubeka ngokwenombolo. Qaphela, ungayidonsi noma uyidonse ngenkani i-geomembrane ngesikhathi sokuthutha ukuze ugweme izinto ezicijile ukuthi zingayibhobozi.

i-geombrane
Ukwakhiwa nokufakwa kwe-geomembrane laying:
I-1) Kufanele idlulele ukusuka phansi iye endaweni ephakeme, ngaphandle kokudonsa ngokuqinile, ishiye umkhawulo we-1.50% wokucwila kwendawo kanye nokwelula. Uma kucatshangelwa isimo sangempela salo msebenzi, umthambeka uzobekwa ngokulandelana phezulu ukuya phansi.
2) Amajoyinti e-longitudinal amafreyimu ancikene akufanele abe kulayini ovundlile ofanayo futhi kufanele anyakaziswe ngaphezu kuka-1M ukusuka kwelinye.
3) Ijoyinti le-longitudinal kufanele okungenani libe yi-1.50m kude nonyawo lwedamu kanye nonyawo olugobile, futhi kufanele lubekwe endaweni eyisicaba.
4) Qala ngengemuva elingemuva le-slope kuqala.
I-5) Uma ubeka umthambeko, isiqondiso sefilimu kufanele sihambisane ngokuyisisekelo nomugqa we-slope.
Ukubeka i-Slope: Ngaphambi kokubeka i-geomembrane ephikisana nokuphuma emthambekeni, indawo yokubeka kufanele ihlolwe futhi ikalwe. Ngokusekelwe kusayizi olinganisiwe, ulwelwesi olunganqamuki olufana nosayizi wendawo yokugcina impahla kufanele luthuthwe luyiswe esigabeni sokuqala somsele wokuhlanganisa. Ngesikhathi sokubeka, indlela elula "yokusunduza nokubeka" kusukela phezulu kuya phansi kufanele yamukelwe ngokuvumelana nezimo zangempela esizeni. Endaweni emise okwefeni, kufanele isikwe ngokufanelekile ukuze kuqinisekiswe ukuthi zombili iziphetho ezingenhla nezingezansi zibambelele ngokuqinile.

i-geombrane.
Ukubeka phansi: Ngaphambi kokubeka i-geomembrane ephikisana ne-seepage, indawo yokubeka kufanele ihlolwe futhi ilinganiswe. Ngokusekelwe kusayizi olinganisiwe, ulwelwesi olumelene nokubonakala kwekhasi olufana nosayizi wendawo yokugcina impahla kufanele luhanjiswe endaweni ehambisanayo. Lapho ibeka, iphushwa ngesandla ibheke endaweni ethile. Ukuqondanisa nokuqondanisa: Ukubekwa kwe-geomembrane ye-HDPE, kungakhathaliseki ukuthi kumithambeka noma phansi kwesayithi, kufanele kube bushelelezi futhi kuqonde, kugweme imibimbi nama-ripples, ukuze kuqondiswe futhi kuqondiswe ama-geomembranes amabili. Ububanzi bokugqagqana buvamise ukuba ngu-10cm nhlangothi zombili ngokwezidingo zokuklama.
Ukucindezela ifilimu: Sebenzisa amasaka esihlabathi ukuze ucindezele ngesikhathi i-geomembrane ye-HDPE eqondanisiwe futhi eqondaniswe ukuze uvimbele umoya nokudonsa.
Ukubeka emgodini okusetshenzwa kulengwa kuzo: Inani elithile le-anti-sepage membrane kufanele ligcinwe phezulu komsele okusetshenzwa kulengwa kuzo ngokwezidingo zokuklama ukuze kulungiselelwe ukucwila nokunwetshwa kwendawo.
Ijoyinti le-longitudinal: Ingxenye ekhuphukayo ingaphezulu, ingxenye eyehlayo ingezansi, futhi kunobude bokugqagqana obanele=15cm. Ngemuva kokwamukelwa kwe-bentonite pad laying, indawo ibekwe ngesandla ngendlela ethile.
