Busto aan biyuhu lahayn oo ka kooban Bentonite
Soo bandhigida alaabta:
Busta-biyoodka 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, bakhaarrada saliidda iyo qashinka kiimikada, iwm. iyo dhar aan tolmo lahayn oo u dhexeeya habka irbadda-feeryo galay derin bentonite impermeable samayn kartaa badan oo bannaan fiber yar yar, waa qayb bentonite ma 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 doonto 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 ℃ hoose 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, fududahay in la dayactiro;xitaa ka dib dhamaadka biyo-celinta (seepage), sida dhaawaca shil ee lakabka biyuhu, ilaa inta qaybta jaban ee dayactirka fudud, waxaad dib u heli kartaa waxqabadka asalka ah ee biyuhu.
4, Waxqabadka marka la eego heerka sare ee saamiga, isticmaalka aad u ballaaran.
