Amakariso ya Bentonite adapfa amazi/amatasi adapfa amazi
Ibisobanuro bigufi:
I. Ibisobanuro by'ibicuruzwa: Ubuso bw'igice ≥ 4000g/㎡, ubugari bwa metero 4-6.
II. Ibiranga imikorere
Ugereranyije n'ibumba rito, rifite ibyiza nko kuba rito, uburemere bworoshye, ubworoherane bwiza, ubushobozi bwo gukora neza, imbaraga nyinshi zo gukata, uburyo bworoshye bwo kubaka, no kwihutisha guturwa mu buryo butaringaniye.
Izina ry’amabuye y’agaciro rya bentonite ni montmorillonite. Bentonite karemano igabanyijemo ibice bibiri bitewe n’imiterere yayo: ishingiye kuri sodium n’ishingiye kuri kalisiyumu. Bentonite ifite umwihariko wo kubyimba iyo ihuye n’amazi. Muri rusange, bentonite ishingiye kuri kalisiyumu ikura ikagera ku ngano eshatu gusa iyo yijimye, mu gihe bentonite ishingiye kuri sodium yinjiza uburemere bwayo inshuro eshanu mu mazi, ikagera ku ngano irenga 15-17 y’umwimerere wayo. Gufunga bentonite ishingiye kuri sodium hagati y’ibice bibiri by’ibikoresho bya geosynthetic bitanga uburinzi n’imbaraga, biha GCL imbaraga zimwe na zimwe zo gukata.
III. Gukoresha ibicuruzwa
Uburingiti butagira amazi bwa Benton ni ibikoresho bya geosynthetic byihariye byagenewe gukumira amazi mu biyaga by’ubukorano n’amazi, aho imyanda ijugunywa, muri gareji zo munsi y’ubutaka, mu busitani bwo hejuru y’inzu, mu bidendezi, mu bubiko bw’amavuta, no mu bubiko bw’ibinyabutabire. Bigizwe na bentonite nini cyane ishingiye kuri sodium yuzuye hagati y’imyenda yakozwe mu buryo bwihariye ya geotextile n’itarimo ubudodo. Umutambara wo kwirinda amazi wa bentonite, ukorwa hakoreshejwe uburyo bwo gupfumura urushinge, ukora ahantu hanini hato hanini hato, ukabuza uduce twa bentonite gutembera mu cyerekezo kimwe. Iyo uhuye n’amazi, ukora urwego rumwe, rumeze nk’urwa gel rwinshi rudapfa amazi ruri muri uwo mutambara, bikarinda amazi kuva.
