Geotextiles (tseem hu ua non-woven fabrics) raws li cov khoom siv lim tau siv ntau dua hauv kev txuag dej, tshwj xeeb hauv cov dej num, kev tsim kho dej, thiab cov dej ua haujlwm.
Raws li cov khoom siv lim tshiab, geotextile ua si lub luag haujlwm tseem ceeb hauv kev tiv thaiv-seepage hauv dej kev txuag dej num. Rau nws daim ntawv thov, qhov kev xaiv xaiv ncaj qha rau kev nyab xeeb thiab kev lag luam hauv kev tsim kho engineering.
Kev tsim qauv tsim thiab kev tsim kho ntawm geotextile raws li cov khoom siv lim yuav tsum muaj peb txoj haujlwm ntawm kev tuav dej, permeability thiab tiv thaiv thaiv, thiab nws lub zog yuav tsum ua tau raws li cov cai. Hauv kev xyaum, cov ntsiab lus hauv qab no yog qhib rau kev sib tham.
(1) Geotextiles muaj ntau hom thiab qhov tshwj xeeb, thiab lawv cov av khaws cia, permeability, thiab tiv thaiv cov khoom thaiv yog qhov sib txawv. Raws li cov ntawv thov engineering tej yam xwm txheej, cov yam ntxwv ntawm kev tiv thaiv av, particle muaj pes tsawg leeg thiab seepage yam ntxwv ntawm cov tsis xav tau raug hloov mus rau qhov chaw geotextile. Nyob rau tam sim no, cov ntawv thov tshwj xeeb thiab xaiv ntawm geotextile hauv engineering feem ntau tsis sib txawv los ntawm cov xwm txheej saum toj no.
(2) Geotextiles raug rau cov xwm txheej tsis sib luag thaum siv, thiab raug nruj, nrawm, kua muag, thiab tawg thaum lub sijhawm tsim thiab tsheb thauj mus los. Geotextiles yuav tsum muaj qee lub zog kom ua tau raws li cov cai saum toj no.
(3) Hauv cov qauv duab thiab cov lus qhia tam sim no, feem ntau tsuas yog g / m 2 yog qhov yuav tsum tau ua, thiab tsis tshua muaj hais txog qhov tseem ceeb tshaj qhov ua tau zoo ntawm kev lim dej thiab qhov ntsuas lub zog.
