Chiyambi ndi zofunikira zomangira za bulangeti losalowa madzi la sodium bentonite

Bulangeti losalowa madzi lotupa ndi mtundu wa zinthu zopangidwa ndi geosynthetic zomwe zimagwiritsidwa ntchito makamaka popewa kutayikira kwa madzi m'nyanja zopanga, malo otayira zinyalala, m'magalaji apansi panthaka, m'minda ya padenga, m'madziwe, m'malo osungira mafuta ndi m'mabwalo a mankhwala. Limapangidwa ndi bentonite yochokera ku sodium yotupa kwambiri yodzazidwa pakati pa nsalu zapadera za geotextile ndi nsalu zosalukidwa. Mpando wa bentonite woletsa kutuluka kwa madzi wopangidwa ndi njira yobowola singano ukhoza kupanga malo ang'onoang'ono ambiri a ulusi. Tinthu ta Bentonite sitingayende mbali imodzi. Mukakumana ndi madzi, wosanjikiza wosalowa madzi wa colloidal wofanana komanso wokhuthala kwambiri umapangidwa mu mphasa.

Zinthu Zogulitsa:

Chiŵerengero chapamwamba cha magwiridwe antchito ndi mtengo komanso chosinthasintha kwambiri. Mtundu wa zinthuzo umatha kufika mamita 6, zomwe zimapangitsa kuti ntchito yomanga ikhale yogwira mtima kwambiri.

Kukula kwa ntchito ndi mikhalidwe yogwiritsira ntchito: Yoyenera oyang'anira maboma (Kutaya zinyalala), Kusamalira madzi, kuteteza chilengedwe, nyanja yopangidwa ndi nyumba zotchingira madzi pansi pa nthaka komanso mapulojekiti oletsa madzi kulowa.

Zofunikira pa zomangamanga:

1. Musanapange bulangeti losalowa madzi la bentonite, gawo loyambira liyenera kuyang'aniridwa. Gawo loyambira liyenera kukhala losalala komanso lopanda mabowo, madzi, miyala, mizu ndi zinthu zina zakuthwa.

2. Pa nthawi yogwira ndi kupanga bulangeti losalowa madzi la bentonite, kugwedezeka ndi kugwedezeka kuyenera kupewedwa momwe zingathere, ndipo thupi la bulangeti liyenera kupewedwa kupindika kwakukulu. Ndi bwino kuliyika pamalo ake nthawi imodzi.

3. Mu GCL Pambuyo pokhazikitsa ndi kuvomereza, ntchito yobwezeretsa iyenera kuchitika mwachangu momwe zingathere. Ngati ikugwirizana ndi HDPE, geomembrane iyenera kukonzedwa ndi kulumikizidwa nthawi yake kuti isanyowe kapena kusweka ndi mvula.

Njira yothirira madzi ndi iyi: tinthu tating'onoting'ono tochokera ku sodium bentonite tomwe timasankhidwa kuti tigwiritsidwe ntchito pa bulangeti lothirira madzi la bentonite tingatambasulidwe nthawi zoposa 24 tikakumana ndi madzi, zomwe zimapangitsa kuti ikhale njira yofanana ya colloidal yokhala ndi kukhuthala kwakukulu komanso kutayika kochepa kwa kusefa. Pansi pa kuletsa zigawo ziwiri za geotextile, bentonite imasintha kuchoka pa kusokonezeka kupita pakukula mwadongosolo, ndipo zotsatira za kufalikira kosalekeza kwa madzi ndikuti gawo la bentonite lokha limakhala lolimba, motero limakhala ndi mphamvu yosalowa madzi.
