Magumbeze eBentonite asingapindi mvura/mameti asingapindi mvura
Tsananguro pfupi:
I. Magadzirirwo eChigadzirwa: Huremu hwenzvimbo yechikamu ≥ 4000g/㎡, upamhi 4-6m.
II. Hunhu hweMashandiro
Kana tichienzanisa nemapuranga evhu akamanikana, ane zvakanakira zvakaita sehurefu hudiki, huremu hwakareruka, kuchinjika kwakanaka, kushanda zvakanaka kwehuremu, simba guru rekuchekerera, kuvakwa kuri nyore, uye kugona kuchinjika kuti zvisapararire.
Zita rekuti bentonite rine minerals ndi montmorillonite. Bentonite yechisikigo yakakamurwa kuita mapoka maviri zvichienderana nekugadzirwa kwayo kwemakemikari: sodium-based uye calcium-based. Bentonite ine hunhu hwekuzvimba kana yasangana nemvura. Kazhinji, bentonite ine calcium inowedzera kusvika pahuwandu hwayo katatu chete kana yazvimba, nepo bentonite ine sodium-based inopinza huremu hwayo kashanu mumvura, ichikura kusvika pahuwandu hwayo hwepakutanga kanopfuura ka15-17. Kuvhara bentonite ine sodium-based pakati pezvikamu zviviri zve geosynthetic material kunopa dziviriro nekusimbisa, zvichipa GCL simba rakati rekucheka.
III. Kushandiswa Kwechigadzirwa
Magumbeze asingapindi mvura eBenton zvinhu zvakagadzirwa kuti zvidzivirire kudonha kwemvura mumadhamu ekugadzira uye munzvimbo dzinowanikwa mvura, nzvimbo dzekurasira marara, magaraji epasi pevhu, minda yedenga, madziva, nzvimbo dzekuchengetera mafuta, nenzvimbo dzekuchengetera makemikari. Izvi zvinosanganisira bentonite yakakura kwazvo ine sodium yakazadzwa pakati pemachira ekugadzira akagadzirwa zvakasiyana uye asina kurukwa. Bentonite yekudzivirira mvura, inogadzirwa uchishandisa nzira yekuboora netsono, inoumba nzvimbo diki dzakawanda dzefiber, ichidzivirira zvidimbu zvebentonite kuti zvisayerere munzira imwe chete. Kana yasangana nemvura, inoumba layer yakafanana, yakaita segel yakawanda mukati memeti, ichidzivirira kubuda kwemvura zvinobudirira.
