Izingubo zokulala ezingangeni manzi ze-Bentonite/omata abangangeni manzi
Incazelo emfushane:
I. Imininingwane Yomkhiqizo: Ubunzima bendawo yeyunithi ≥ 4000g/㎡, ububanzi 4-6m.
II. Izici Zokusebenza
Uma kuqhathaniswa nama-clay liner ahlanganisiwe, inezinzuzo ezifana nomthamo omncane, isisindo esincane, ukuguquguquka okuhle, ukusebenza kahle kobuningi, amandla aphezulu okusika, ukwakhiwa okulula, kanye nokuzivumelanisa nezimo nokulingana.
Igama le-mineralological le-bentonite yi-montmorillonite. I-bentonite yemvelo ihlukaniswe kakhulu ngezigaba ezimbili ngokuya ngokwakheka kwayo kwamakhemikhali: esekelwe ku-sodium kanye nesekelwe ku-calcium. I-Bentonite inezici zokuvuvukala lapho ithintana namanzi. Ngokuvamile, i-bentonite esekelwe ku-calcium ikhula ibe cishe kathathu kuphela ngomthamo wayo lapho ivuvukala, kuyilapho i-bentonite esekelwe ku-sodium imunca isisindo sayo ngokuphindwe kahlanu emanzini, ikhula ibe ngaphezu kwezikhathi eziyi-15-17 ngomthamo wayo wokuqala. Ukuvala i-bentonite esekelwe ku-sodium phakathi kwezingqimba ezimbili zezinto zokwenziwa kwe-geo kunikeza isivikelo nokuqinisa, okunikeza i-GCL amandla athile okusika.
III. Isicelo Somkhiqizo
Izingubo zokulala ezingangeni manzi zeBenton ziyizinto zokwenziwa kwe-geosynthetic ezenzelwe ngqo ukuvimbela ukuvuza kwamanzi emachibini okwenziwa kanye nasezicini zamanzi, ezindaweni zokulahla udoti, emagaraji angaphansi komhlaba, ezingadini eziphahleni, emachibini okubhukuda, ezindaweni zokugcina uwoyela, nasezindaweni zokugcina amakhemikhali. Ziqukethe i-bentonite ebanzi kakhulu esekelwe ku-sodium egcwele phakathi kwendwangu ye-geotextile ehlanganisiwe eyenziwe ngokukhethekile kanye nendwangu engalukiwe. Umata wokuvimbela amanzi we-bentonite, owenziwe ngendlela yokubhoboza inaliti, wakha izikhala eziningi ezincane zefayibha, uvimbela izinhlayiya ze-bentonite ukuthi zingagelezi ohlangothini olulodwa. Lapho zithintana namanzi, zakha ungqimba olungangeni manzi olufana nejeli ngaphakathi komata, okuvimbela ngempumelelo ukuvuza kwamanzi.
