Busto aan biyuhu lahayn oo isku jira Bentonite
Soo bandhigida alaabta:
Bustada aan biyaha lahayn ee Bentonite Composite waa qalab geosynthetic ah oo gaar ah oo loo isticmaalo harooyinka macmalka ah iyo sifooyinka biyaha, meelaha qashin-qubka, garaashyada dhulka hoostiisa ah, jardiinooyinka saqafka, barkadaha, bakhaarada saliidda iyo qashinka kiimikada, iwm. iyo dhar aan tolmo lahayn oo u dhexeeya habka irbadda-ku-dhufashada ee gogosha bentonite ee aan la taaban karin waxay samayn kartaa meelo badan oo fiber yar, waa Qaybaha bentonite uma qulquli karaan sida jihada. Marka biyaha la kulmo, lakabka cufnaanta sare ee jeel-u eg ee aan biyaha lahayn ayaa lagu sameeyay sariirta, taasoo si wax ku ool ah uga hortagaysa daadinta biyaha.
Astaamaha Alaabta:
1, Waxay leedahay sifooyin aad u fiican oo aan biyuhu lahayn iyo kuwa aan la taaban karin, cadaadiska hydrostatic impermeable ilaa 1.0MPa ama ka badan, permeability 5 × 10-11cm / s, unit bed bentonite tayada 5kg / ㎡, bentonite waa alaabta dabiiciga ah ee dabiiciga ah, ma noqon doono falcelinta gabowga, adkeysiga wanaagsan; oo aan wax saameyn xun ku yeelan doonin deegaanka waa walxo deegaan ahaan u wanaagsan;.
2, Waxay leedahay dhammaan sifooyinka qalabka geotextile, sida kala-soocidda, xoojinta, ilaalinta, sifeynta, iwm., dhismuhu waa sahlan yahay oo aan xaddidnayn heerkulka deegaanka dhismaha, 0 ℃ hoos ayaa sidoo kale la dhisi karaa. dhismuhu si fudud u jiifi buste-biyoodka GCL oo si siman dhulka u dhigay, dhisme toosan ama badheedh ah, oo leh ciddiyo iyo weel si ay u hagaajiyaan, iyo dhabta hadba sida loo baahdo;.
3, Si fudud loo dayactiro; xitaa ka dib dhamaadka biyo-celinta (seepage), sida dhaawaca shilalka ah ee lakabka biyuhu, ilaa inta qaybta jaban ee dayactirka fudud, waxaad dib u heli kartaa waxqabadka asalka ah ee biyuhu.
4, Marka la eego waxqabadka sare ilaa saamiga qiimaha, isticmaalka aad u ballaaran.
