Lub luag haujlwm ntawm Geotextile yog dab tsi? Geotextile yog cov khoom siv geosynthetic permeable tsim los ntawm kev siv tshuab xaws, uas yog nyob rau hauv daim ntaub, los yog geotextile. Nws cov yam ntxwv tseem ceeb yog lub teeb yuag, zoo tag nrho txuas ntxiv, kev tsim kho yooj yim, siab tensile zog, thiab corrosion kuj. Geotextiles tau muab faib ua wovengeotextilesthiab non-woven geotextiles. Cov qub yog woven los ntawm ib leeg los yog ntau cov ntaub ntawm cov lo lo ntxhuav, los yog woven los ntawm ca filaments txiav los ntawm nyias zaj duab xis; Cov tom kawg yog tsim los ntawm luv fibers los yog tshuaj tsuag spun ntev fibers randomly nteg rau hauv flocs, uas yog ces mechanically qhwv (needle punched), thermally bonded, los yog chemically bonded.
Dab tsi yog lub luag haujlwm ntawmGeotextile?:
(1) Kev sib cais ntawm cov khoom sib txawv
Nruab nrab ntawm roadbed thiab foundation; Nruab nrab ntawm railway subgrade thiab ballast; Nruab nrab ntawm qhov chaw pov tseg thiab lub hauv paus pob zeb crushed; Nruab nrab ntawm cov geomembrane thiab cov xuab zeb ntws txheej; Nruab nrab ntawm lub hauv paus thiab embankment av; Nruab nrab ntawm lub hauv paus av thiab lub hauv paus pawg; Hauv qab kev taug kev, chaw nres tsheb, thiab chaw ua kis las; Nruab nrab ntawm cov lim dej tsis zoo thiab cov txheej txheem dej; Nruab nrab ntawm thaj chaw sib txawv ntawm lub ntiaj teb dams; Siv cov txheej txheem tshiab thiab qub asphalt.
(2) Cov khoom siv txhawb zog thiab kev tiv thaiv
Siv rau ntawm lub hauv paus mos ntawm embankments, railways, landfills, thiab chaw ua si; Siv los ua cov pob khoom geotechnical; Txhim kho rau embankments, av dams, thiab slopes; Raws li lub hauv paus kev txhawb nqa hauv thaj chaw karst; Txhim kho cov kabmob muaj peev xwm ntawm cov hauv paus ntiav; Kev txhawb zog ntawm lub hauv paus pawg cap; Tiv thaiv cov geotextile membrane los ntawm punctured los ntawm lub hauv paus av; Tiv thaiv impurities lossis pob zeb txheej hauv qhov chaw pov tseg los ntawm punctureing geomembrane; Vim muaj kev sib txhuam siab, nws tuaj yeem ua rau txoj kab nqes zoo dua ntawm kev sib xyaw geomembranes.
(3) Rov qab pom
Nyob rau hauv lub pob zeb crushed ntawm txoj kev nto thiab tshav dav hlau txoj kev los yog nyob rau hauv railway ballast; Nyob ib ncig ntawm lub pob zeb dej txheej; Nyob ib ncig ntawm underground perforated cov kav dej; Hauv qab qhov chaw pov tseg uas tsim cov kua qaub; Tiv thaiv tusgeotextilenetwork tiv thaiv cov av los ntawm invading; Tiv thaivgeosyntheticcov ntaub ntawv los tiv thaiv av hais los ntawm invading.
(4) Cov dej ntws tawm
Raws li txoj kab ntsug thiab kab rov tav rau lub ntiaj teb dams; Kab rov tav ntws ntawm pre pressed embankment hauv qab ntawm lub hauv paus mos; Raws li ib qho kev thaiv txheej rau cov dej hauv av capillary kom nce nyob rau hauv cov cheeb tsam rhiab heev; Capillary barrier txheej rau ntws ntawm saline alkali tov nyob rau hauv qhuav av; Raws li lub hauv paus txheej ntawm articulated qhob thaiv txoj kab nqes kev tiv thaiv.
