Astm Standard Tsis Woven Geotextile
Nws yog lub siab - koob kev ua tau zoo- punched nruam filament geotextile tsim los ntawm polyester (PET) los yog polypropylene (PP) fibers. Nws yog tsim los rau kev sib cais, pom, kev tso dej, kev txhawb nqa, thiab kev tiv thaiv hauv kev tsim vaj tsev, kev cog qoob loo, kev tsim kho, thiab kev ua haujlwm hydraulic.
Engineering Nonwoven Geotextile rau Infrastructure
Qhov txuas txuas txuas ntxiv no tsis yog woven geotextile yog tsim los siv cov koob tshaj - xuas nrig ntaus thev naus laus zis, tsim lub siab - lub zog peb - qhov loj me ntawm cov qauv. Nws muab cov hydraulic conductivity zoo heev, pom kev ruaj ntseg, thiab kev ua haujlwm ntawm cov khoom siv kho qhov muag.
Nws yog dav siv nyob rau hauv kev tiv thaiv cov dej khib nyiab, txoj kev loj subgrade reinforcement, railway foundation stabilization, dam filtration layers, thiab coastal protection structures.
