Intangiriro n'ibisabwa mu bwubatsi bw'igitambaro kidakingirwa amazi cya sodium bentonite

Igitambaro kidapfa amazi kibyimba ni ubwoko bw'ibikoresho bya geosynthetic byihariye bikoreshwa mu gukumira amazi ava mu biyaga by'ubukorano, aho imyanda ijugunywa, muri gareji zo munsi y'ubutaka, mu busitani bwo hejuru, mu bisenge, mu bigega, mu bubiko bw'amavuta n'ahantu ho kubika imyanda. Gikozwe muri bentonite ishingiye kuri sodium ibyimba byinshi yuzuye hagati y'imyenda yihariye ya geotextile n'indi idafunze. Umutambaro wa bentonite urinda amazi ukorwa hakoreshejwe uburyo bwo gukubita urushinge ushobora gukora ahantu henshi hato hafite fibre. Uduce twa Bentonite ntidushobora gutembera mu cyerekezo kimwe. Iyo uhuye n'amazi, urwego rumwe kandi rufite ubucucike bwinshi bwa colloidal rukorwa muri uwo mutambaro.

Ibiranga Ibicuruzwa:

Igipimo cy'imikorere n'igiciro kiri hejuru kandi gifite ubushobozi bwo gukora ibintu byinshi bitandukanye. Ingano y'ibicuruzwa ishobora kugera kuri metero 6, ibi bikaba byongera cyane imikorere myiza y'inyubako.

Ingano y'ikoreshwa n'amategeko agenga ikoreshwa: Bikwiriye ubuyobozi bw'umujyi (Imyanda), kubungabunga amazi, kurengera ibidukikije, ibikorwa byo kurinda amazi mu kiyaga n'inyubako zikorerwamo ibikorwa byo kwirinda amazi munsi y'ubutaka no gukumira amazi.

Ibisabwa mu bwubatsi:

1. Mbere yo gukora igitambaro cya bentonite kidapfa amazi, urwego rw'ibanze rugomba kugenzurwa. Urwego rw'ibanze rugomba kuba rudafunze kandi rudafite ibinogo, amazi, amabuye, imizi n'ibindi bintu bityaye.

2. Mu gihe cyo gufata no kubaka igitambaro cya bentonite kidapfa amazi, guhinda no gutera ingaruka bigomba kwirindwa uko bishoboka kose, kandi ikirenge kinini cy'igitambaro kigomba kwirindwa. Ni byiza kugishyira ahantu hamwe.

3. Muri GCL Nyuma yo kuyishyiraho no kuyishyiramo, imirimo yo kuyisubiza inyuma igomba gukorwa vuba bishoboka. Iyo ikoranye na HDPE. Imbuto ya geomembrane igomba gushyirwaho kaburimbo no kuyisudira ku gihe kugira ngo idatoha cyangwa ngo ivunike bitewe n'imvura.

Uburyo bwo kwirinda amazi ni ubu: agace ka bentonite gashingiye kuri sodium katoranijwe mu gitambaro cyo kwirinda amazi cya bentonite gashobora kwaguka inshuro zirenga 24 iyo kashyizwe mu mazi, bigatuma gakora sisitemu imwe ya colloidal ifite ubukana bwinshi kandi itakaza ubushobozi bwo kuyungurura. Mu gihe habayeho urwego rubiri rwa geotextile, bentonite ihinduka kuva ku ihindagurika ijya kwaguka neza, kandi ingaruka zo kwaguka k'amazi kenshi ni uko urwego rwa bentonite ubwarwo ruhinduka rukibyimba, bityo rukagira ingaruka zo kwirinda amazi.
