Nws feem ntau yog siv rau kev kho mob tiv thaiv seepage ntawm cov pas dej thiab cov kwj dej ntws, thiab kev kho mob tiv thaiv kev ua qias tuaj ntawm cov khib nyiab pov tseg.
Cov Khoom Piav Qhia
Cov geomembrane sib xyaw yog cov khoom siv tsis muaj dej uas muaj geotextile thiab geomembrane, uas feem ntau yog siv rau kev tsis muaj dej nkag. Cov geomembrane sib xyaw yog muab faib ua ib daim ntaub thiab ib daim nyias nyias thiab ob daim ntaub thiab ib daim nyias nyias, nrog rau qhov dav dav ntawm 4-6m, qhov hnyav ntawm 200-1500g / m2, cov cim qhia kev ua tau zoo ntawm lub cev thiab lub tshuab xws li tensile, tear resistance thiab ru tsev tawg. Nws tuaj yeem ua tau raws li qhov xav tau ntawm kev txuag dej, kev tswj hwm hauv nroog, kev tsim kho, kev thauj mus los, subway, qhov av thiab lwm yam kev tsim kho vaj tse. Vim yog kev xaiv cov ntaub ntawv polymer thiab ntxiv cov neeg sawv cev tiv thaiv kev laus hauv cov txheej txheem ntau lawm, nws tuaj yeem siv rau hauv qhov chaw kub tsis zoo.
Vaj tse
