Nhanganyaya uye zvinodiwa zvekuvaka zve sodium bentonite isina mvura blanket

Gumbeze risingapindi mvura rinozvimba imhando yezvinhu zve geosynthetic zvinoshandiswa kudzivirira kudonha kwemvura mumadziva ekugadzira, nzvimbo dzekurasira marara, magaraji epasi pevhu, minda yedenga, madziva, nzvimbo dzekuchengetera mafuta uye nzvimbo dzemakemikari. Yakagadzirwa ne bentonite ine sodium yakazvimba yakawanda yakazadzwa pakati pemachira e geotextile akakosha uye asina kurukwa. Bentonite inodzivirira kudonha kwemvura yakagadzirwa nenzira yekubaya netsono inogona kugadzira nzvimbo diki dzakawanda dzefiber. Bentonite particles haigone kuyerera ichienda kune rimwe divi. Painosangana nemvura, layer ye colloidal isina mvura yakafanana uye ine density high-density inoumbwa mumeti.

Zvimiro zveChigadzirwa:

Mutengo wepamusoro uye kushanda kwakawanda. Rudzi rwechigadzirwa runogona kusvika mamita matanhatu, izvo zvinovandudza zvikuru kushanda kwechivakwa.

Mashandisirwo azvo uye mamiriro ekushandiswa: Zvakakodzera hutungamiriri hwemaguta (Kuisa marara), kuchengetedza mvura, kuchengetedzwa kwezvakatipoteredza, mapurojekiti ekudzivirira mvura pasi pevhu uye ekudzivirira kudonha kwemvura.

Zvinodiwa pakuvaka:

1. Musati magadzira jira risingapindi mvura rebentonite, jira repasi rinofanira kuongororwa. Rutivi rwepasi runofanira kunge rwakatsetseka uye rwakati sandara, rusina makomba, mvura, matombo, midzi nezvimwe zvinhu zvakapinza.

2. Pakubata nekugadzira jira rekudzivirira mvura rebentonite, kudedera nekukanganisa kunofanira kudzivirirwa zvakanyanya sezvinobvira, uye kukombama kukuru kwemuviri wejira kunofanira kudzivirirwa. Zvakanaka kuriisa panzvimbo imwe chete.

3. MuGCL Mushure mekuiswa nekugamuchirwa, basa rekugadzirisa madziro rinofanira kuitwa nekukurumidza sezvinobvira. Kana zvikashandiswa pamwe chete HDPE. Geomembrane inofanira kugadzirwa nematombo uye kusungirirwa panguva yakakodzera kudzivirira kuti isanyorove kana kuputsika nemvura.

Nzira yekudzivirira mvura ndeiyi: bentonite ine sodium-based particle bentonite inosarudzwa pagumbeze rekudzivirira mvura rebentonite inogona kukura kanopfuura makumi maviri nemana kana yaiswa mumvura, zvichiita kuti igadzire system yakafanana ye colloidal ine viscosity yakakura uye kurasikirwa kwakaderera kwekusefa. Pasi pekudziviswa kwezvikamu zviviri zve geotextile, bentonite inoshanduka kubva pakusagadzikana kuenda pakuwedzera kwakarongeka, uye mhedzisiro yekuwedzera kunwa mvura nguva dzose ndeyekuti bentonite layer pachayo inova yakaoma, nokudaro iine simba rekudzivirira mvura.
