Geotechnical lev rau channel seepage tiv thaiv thiab ntws
Khoom Taw Qhia:
Geo textile lev yog ib yam tshiab ntawm geo hluavtaws cov khoom ua los ntawm fused thiab nteg mesh ntawm disordered filaments.Nws muaj kev kub siab ua haujlwm, siab ceev ntawm qhov qhib thiab muaj tag nrho cov dej sib sau ua ke thiab kab rov tav ua haujlwm.Cov qauv yog peb-dimensional geo membrane core nrog koob-punched perforated non-woven geo textiles ntawm ob sab.Qhov peb-dimensional geo mesh core ntws dej hauv av sai sai thiab muaj lub pore txij nkawm ntawm nws tus kheej, uas thaiv cov dej capillary nyob rau hauv siab loads.Nws kuj ua raws li kev thaiv kev thaiv.
Khoom nta:
1. Muaj kev kub siab kuj, siab qhib qhov ntom ntom, nrog txhua-taws kev sau dej thiab kab kab rov tav kev ua haujlwm.
2. Tom qab geotextile lev yog compounded nrog non-woven geotextile, nws muaj peev xwm sau cov dej nag nkag los ntawm cov av npog txheej los yog cov dej phwj tawm los ntawm lub vaj nws tus kheej nyob rau hauv lub faus kaw npog txheej, thiab siv nws tshwj xeeb tso kua dej muaj nuj nqi kom tso tawm los ntawm lub vaj. geotextile lev sandwich txheej nyob rau hauv ib qho kev txiav txim raws li cov kev xav tau ntawm engineering, tsis muaj silting.Yog li ntawd, nws tuaj yeem zam qhov teeb meem zawv zawg vim qhov dej nqus dej saturation ntawm cov av npog txheej.
3. Geomat lev tuaj yeem tsis tsuas yog ntws dej, tab sis kuj tso cov roj methane uas tsim los ntawm fermentation hauv cov av (tshwj xeeb tshaj yog cov khib nyiab pov tseg), uas yog tshwj xeeb tshaj yog haum rau kev siv hauv kev pov tseg.
4. geotechnical lev thiab HDPE ua ke daim ntawv thov, tib lub sijhawm tuaj yeem ua lub luag haujlwm zoo hauv kev tiv thaiv HDPE membrane los ntawm kev sib tsoo.

Daim ntawv thov:
Nws yog dav siv nyob rau hauv channel seepage tiv thaiv thiab kua dej, roadbed ntws ntawm railways thiab txoj kev loj, rov qab pom ntawm khaws cia.
cov phab ntsa, cov kua dej thiab cov dej noo tiv thaiv cov vaj tse hauv av, cov chaw kho dej phwj tuaj, cov chaw pov tseg thiab lwm cov haujlwm.
