Kodi ntchito ya Geotextile ndi chiyani? Geotextile ndi geosynthetic zinthu zomwe zimatha kulowa mkati mwaukadaulo woluka, zomwe zimakhala ngati nsalu, zomwe zimadziwikanso kuti geotextile. Makhalidwe ake akuluakulu ndi kulemera kopepuka, kupitilira kwabwino konse, kumanga kosavuta, kulimba kwamphamvu kwambiri, komanso kukana dzimbiri. Ma geotextiles amagawidwanso kukhala olukageotextilesndi ma geotextile omwe sanalukidwe. Zoyambazo zimalukidwa kuchokera ku ulusi umodzi kapena zingapo za silika, kapena zolukidwa kuchokera ku ulusi wathyathyathya wodulidwa kuchokera ku mafilimu oonda; Chomalizacho chimapangidwa ndi ulusi waufupi kapena ulusi wopota wopopedwa wautali womwe umayikidwa mwachisawawa mumagulu, omwe kenako amakulungidwa mwamakina (kubayidwa ndi singano), kumangirizidwa motenthetsera, kapena kumangiriridwa ndi mankhwala.

Kodi udindo waGeotextile?:
(1) Kudzipatula pakati pa zinthu zosiyanasiyana
Pakati pa msewu ndi maziko; Pakati pa njanji subgrade ndi ballast; Pakati pa malo otayirapo nthaka ndi tsinde lamwala lophwanyika; Pakati pa geomembrane ndi mchenga ngalande wosanjikiza; Pakati pa maziko ndi mpanda nthaka; Pakati pa maziko nthaka ndi maziko milu; Pansi pa misewu, malo oimikapo magalimoto, ndi malo ochitira masewera; Pakati bwino graded fyuluta ndi ngalande zigawo; Pakati pa madera osiyanasiyana a madamu apansi; Amagwiritsidwa ntchito pakati pa zigawo zatsopano ndi zakale za asphalt.
(2) Zolimbitsa ndi zoteteza
Amagwiritsidwa ntchito pamaziko ofewa a mizati, njanji, malo otayirapo, ndi malo amasewera; Amagwiritsidwa ntchito popanga ma phukusi a geotechnical; Kulimbitsa matanthwe, madamu a nthaka, ndi otsetsereka; Monga kulimbikitsa maziko kumadera a karst; Kupititsa patsogolo mphamvu yobereka ya maziko osaya; Kulimbikitsa pa maziko mulu kapu; Pewani nembanemba ya geotextile kuti isabooledwe ndi nthaka yapansi; Pewani zonyansa kapena zigawo za miyala m'nthaka kuti zisaboole geomembrane; Chifukwa cha kukana kwamphamvu kwambiri, zimatha kubweretsa kukhazikika kotsetsereka pamagulu a geomembranes.
(3) Sefa mmbuyo
Pansi pa mwala wosweka wa msewu pamwamba ndi bwalo la ndege msewu kapena pansi njanji ballast; Pansi pa miyala ngalande wosanjikiza; Pansi pansi perforated ngalande mipope; Pansi pa malo otayirapo nthaka omwe amapanga leachate; Kutetezageotextilemaukonde kuti tinthu tating'ono ting'onoting'ono zisalowe; Tetezanigeosyntheticzinthu zoteteza kuti tinthu tating'ono ting'onoting'ono zisalowe.

(4) Ngalande
Monga ofukula ndi yopingasa ngalande ngalande madamu lapansi; Kukhetsa kopingasa kwa mpanda woponderezedwa kale pansi pa maziko ofewa; Monga chotchinga chosanjikiza cha madzi apansi panthaka kuti akwere m'malo ovuta kuzizira; Capillary chotchinga wosanjikiza kwa otaya saline alkali njira mu nthaka youma; Monga m'munsi wosanjikiza wa articulated konkire chipika chitetezo otsetsereka.
