Bustayaal biyuhu aanay bentonite lahayn/roogag biyuhu aanay celin karin
Sharaxaad Gaaban:
I. Tilmaamaha Badeecada: Cufnaanta bedka cutubka ≥ 4000g/㎡, ballac 4-6m.
II. Astaamaha Shaqada
Marka la barbardhigo dahaarka dhoobada ee isku dhafan, waxay leedahay faa'iidooyin sida mug yar, miisaan fudud, dabacsanaan wanaagsan, waxqabad cufnaan wanaagsan, xoog xiirid sare, dhismo fudud, iyo la qabsi la'aan degitaan aan sinnayn.
Magaca macdanta ee bentonite waa montmorillonite. Bentonite-ka dabiiciga ah waxaa inta badan loo qaybiyaa laba qaybood iyadoo loo eegayo qaab-dhismeedkiisa kiimikada: ku salaysan sodium iyo ku salaysan calcium. Bentonite wuxuu leeyahay astaamaha bararka marka uu la xiriiro biyaha. Guud ahaan, bentonite-ka ku salaysan calcium wuxuu ku fidaa qiyaastii saddex jeer mugga u gaarka ah marka uu bararo, halka bentonite-ka ku salaysan sodium uu nuugo shan jeer miisaankiisa biyaha, isagoo ku fidaya in ka badan 15-17 jeer mugga asalka ah. Xidhitaanka bentonite-ka ku salaysan sodium inta u dhaxaysa laba lakab oo walxo geosynthetic ah waxay bixisaa ilaalin iyo xoojin, taasoo siinaysa GCL xoog guud oo goyn ah.
III. Codsiga Badeecada
Busteyaasha biyaha celiya ee Benton waa agabyo geosynthetic ah oo si gaar ah loogu talagalay ka hortagga wasakhda harooyinka macmalka ah iyo sifooyinka biyaha, meelaha qashinka lagu shubo, garaashyada dhulka hoostiisa mara, beeraha saqafka sare, barkadaha, bakhaarrada saliidda, iyo meelaha kaydinta kiimikada. Waxay ka kooban yihiin bentonite ku salaysan sodium oo aad u ballaaran oo lagu buuxiyay maro geotextile ah oo si gaar ah loo sameeyay iyo kuwa aan tolnayn. Derbiga biyaha celiya ee bentonite, oo lagu sameeyay habka feeraha irbadda, wuxuu sameeyaa meelo badan oo yar yar oo fiber ah, taasoo ka hortagaysa in walxaha bentonite ay hal jiho u socdaan. Marka ay la kulmaan biyaha, waxay samaysaa lakab biyo celiya oo isku mid ah oo u eg jel oo cufnaan sare leh oo ku jira roogga, taasoo si wax ku ool ah uga hortagaysa daadashada biyaha.
