Kushandiswa kweFilament Geotextiles muRailway Engineering

inonyanya kuzivikanwa ndeyekushandiswa kwefilament geotextile mumigwagwa mikuru.Muchokwadi, inoshandiswawo zvakanyanya muinjiniya yechitima.Uye zvakare, filament geotextile zvinhu zvagara zvichinyatsozivikanwa mune njanji engineering application.Iyo yekumisikidzwa kwe geotextile ichatemerwa pane saiti, uye hunhu hunodiwa hauzove pasi pe200g/㎡.Chitupa chekutumira chichaongororwa.Iyo geotextile inofanirwa kuendeswa muimba yekuchengetera zvinhu, uye haizoonekwe nezuva mumhepo yakashama.Iyo geotextile yakachengetwa kweanopfuura mwedzi mitanhatu haifanirwe kushandiswa.Iyo geotextile haizove neyakachinjika mubatanidzwa, uye kureba kunopindirana kureba hakuzove pasi pe1m. Iyo yekuisa ichave yakati sandara uye yakanyatso zorora.Mushure mekuisa iyo geotextile pagravel layer, tarisa kana gumbo repamakumbo rakakora.Paunenge uchidururira uye uchipwanya mutsara wekongiri wakajeka, dzivirira dhaka kuti risapinde mumatombo.Panguva yekudururwa uye kuputika kwebheti slab, tarisa chikamu chepombi yemvura nechikamu.Dredge uye bvisa sundries chero nguva.Filament geotextile yagara iri yedu yatinoda mumapurojekiti asingapindi mvura uye anopesana nepeji, nekuti inogoneka geosynthetics yakagadzirwa neshinda dzekugadzira kuburikidza nekubaya tsono kana kuruka.
Chigadzirwa chakapedzwa chiri muchimiro chejira, nehupamhi hwese 2-6.2 metres uye huremu hwe180-670 g/㎡.Panguva imwecheteyo, ine yakanakisa kusefa, yekuzviparadzanisa nevamwe, kusimbisa uye kudzivirira, yakakwirira tensile simba, yakanaka permeability, yakakwirira tembiricha kuramba, nechando kuramba, kuchembera kuramba, corrosion kuramba uye mamwe maitiro akanaka ekuita.Uye zvakare, iyo filament geotextile pachayo ine machira akanaka emucheka uye kunamatira kwakanaka, Sezvo iyo fiber iri nyoro, ine kumwe kuramba kubvarura, anti-seepage membrane simba uye yakanaka deformation inogoneka, pamwe neakanaka dhizaini rendege.Nzvimbo yakapfava ine mapeji akawanda ine friction coefficient yakanaka, iyo inogona kuwedzera kusungirirwa kwezvikamu zvevhu, kudzivirira kurasikirwa kwezvikamu zvakanaka uye kubvisa mvura yakawandisa panguva imwe chete.Nzvimbo yakapfava ine simba rakanaka rekudzivirira.Naizvozvo, iyo filament geotextile yakashandiswa zvakanyanya muinjiniya yechitima, uye yakawana mabhenefiti ekudzikisa mutengo uye nani mhando.Mumakore achangopfuura, filament geotextile ndechimwe chezvigadzirwa zvepamusoro-soro zvinogadzirwa kubva ku pure polyester raw materials.Inoshandiswa uye inovakwa zvinoenderana nezvinodiwa zveinjiniya yechitima, uye mhedzisiro yacho inocherechedzwa zvichibva paruzivo rwekushandisa kwenguva refu.Kubva pakuvandudzwa kweinjiniya yechitima nefilament geotextile, indasitiri yechitima yeChina yanga ichikura nekumhanya.Chitima chepamusoro chinomhanya chinoshandisa chimwe chezvinhu zvinonyanya kukosha mune isingapindiki uye isina mvura geotextiles.
