Iingubo ezingangeni manzi zeBentonite/iimethi ezingangeni manzi

I. Iinkcukacha zeMveliso: Ubunzima bendawo yeyunithi ≥ 4000g/㎡, ububanzi yi-4-6m.

II. Iimpawu Zokusebenza

Xa ithelekiswa nee-clay liners ezixineneyo, ineenzuzo ezifana nomthamo omncinci, ubunzima obulula, ukuguquguquka okuhle, ukusebenza kakuhle koxinano, amandla aphezulu okucheba, ulwakhiwo olulula, kunye nokuzivumelanisa nokungalingani kokuhlala.

Igama le-mineralological le-bentonite yi-montmorillonite. I-bentonite yendalo yahlulwe kakhulu kwiindidi ezimbini ngokwendlela ebumbeke ngayo iikhemikhali: i-sodium-based kunye ne-calcium-based. I-Bentonite inophawu lokudumba xa idibana namanzi. Ngokubanzi, i-bentonite esekwe kwi-calcium iyanda ibe malunga ne-volume ephindwe kathathu kuphela xa idumba, ngelixa i-bentonite esekwe kwi-sodium ifunxa ubunzima bayo obuphindwe kahlanu emanzini, iyanda ibe ngaphezu kwe-15-17 volume yayo yokuqala. Ukutshixa i-bentonite esekwe kwi-sodium phakathi kweengqimba ezimbini zezinto ze-geosynthetic kubonelela ngokhuseleko kunye nokuqinisa, okunika i-GCL amandla athile okucheba ngokubanzi.

III. Ukusetyenziswa kweMveliso

Iingubo ezingangeni manzi zeBenton zizinto ezidityaniswe ne-geosynthetic ezenzelwe ngokukodwa ukuthintela ukuvuza kwamanzi kumachibi okwenziwa kunye neempawu zamanzi, kwiindawo zokulahla inkunkuma, kwiigaraji ezingaphantsi komhlaba, kwiigadi eziphahleni, kumadama okubhukuda, kwiindawo zokugcina ioyile, nakwiindawo zokugcina iikhemikhali. Ziqulathe i-bentonite esekwe kwi-sodium ebanzi kakhulu ezaliswe phakathi kwe-geotextile edibeneyo eyenziwe ngokukodwa kunye nelaphu elingalukwanga. I-bentonite manzi yokugquma amanzi, eyenziwe ngendlela yokubhoboza inaliti, yenza izithuba ezininzi ezincinci zefayibha, ithintela amasuntswana e-bentonite ukuba angahambi kwicala elinye. Xa idibana namanzi, yenza umaleko ofanayo, ofana nejeli ephezulu ngaphakathi kwi-mat, ithintela ngokufanelekileyo ukuvuza kwamanzi.
