Izingubo zokulala ezingangeni manzi ze-Bentonite/omata abangangeni manzi
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.

Ingubo yesamente yokuvikela ukuvuza kwamanzi eHongyue
Ingubo yesimende yokuvikela ukuthambeka iwuhlobo olusha lwezinto zokuvikela, ezisetshenziswa kakhulu emigwaqweni yasemthambekeni, emfuleni, ekuvikeleni ulwandle nakwamanye amaphrojekthi ukuvimbela ukuguguleka kwenhlabathi kanye nomonakalo womthambekeni. Yenziwe kakhulu ngesimende, indwangu elukiwe kanye nendwangu ye-polyester kanye nezinye izinto ngokucubungula okukhethekile.

Ibhodi lokukhipha amanzi eliwuhlobo lweshidi
Ibhodi lokukhipha amanzi eliwuhlobo lweshidi liwuhlobo lwezinto zokwenziwa kwe-geosynthetic ezisetshenziselwa ukukhipha amanzi. Ngokuvamile lenziwe ngepulasitiki, irabha noma ezinye izinto ze-polymer futhi lisesimeni esifana neshidi. Ubuso balo bunezimo ezikhethekile noma ama-protrusions okwenza imisele yokukhipha amanzi, engaqondisa amanzi ngempumelelo ukusuka endaweni eyodwa kuya kwenye. Livame ukusetshenziswa ezinhlelweni zokukhipha amanzi ezakhiweni, zikamasipala, zengadi kanye neminye imikhakha yobunjiniyela.
