Chii basa reGeotextile?Geotextile chinhu chinopindika che geosynthetic chinogadzirwa nehunyanzvi hwekuruka, chiri muchimiro chejira, inozivikanwawo se geotextile.Hunhu hwayo hukuru huremu huremu, kuenderera kwakanaka kwese, kuvakwa kuri nyore, kusimba kwakakwira, uye kusagadzikana kwekuora.Geotextiles inopatsanurwazve kuita yakarukwageotextilesuye isina-yakarukwa geotextiles.Iyo yekutanga yakarukwa kubva kune imwe chete kana yakawanda tambo yesirika, kana yakarukwa kubva paflat filaments yakachekwa kubva kumafirimu matete;Yekupedzisira inoumbwa neshinda pfupi kana pfapfaidzo yakaruka mafiinzi marefu zvisina tsarukano akaiswa mumaflocs, ayo anobva aputirwa nemuchina (tsono yakabayiwa), inosungwa nemafuta, kana kusungwa nemakemikari.
Basa reiGeotextile?:
(1) Kuzviparadzanisa pakati pezvinhu zvakasiyana
Pakati penzira nenheyo;Pakati penjanji subgrade uye ballast;Pakati pekurasirwa marara nechigadziko chematombo;Pakati pe geomembrane uye sandy drainage layer;Pakati penheyo uye ivhu rekusimudzira;Pakati penheyo ivhu uye nheyo mirwi;Pasi penzira, nzvimbo dzekupaka, uye nzvimbo dzemitambo;Pakati pemasefa asina kukwenenzverwa nemadrainage layers;Pakati penzvimbo dzakasiyana dzemadhamu evhu;Inoshandiswa pakati pezvitsva uye zvekare asphalt layer.
(2) Kusimbisa uye kuchengetedza zvinhu
Inoshandiswa panheyo dzakapfava dzemaembankments, njanji, nzvimbo dzekurasira marara, nenzvimbo dzemitambo;Inoshandiswa kugadzira geotechnical mapakeji;Kusimbiswa kwemateru, madhamu evhu, uye materu;Sekusimbisa hwaro munzvimbo dzekarst;Kuvandudza simba rekutakura kwenheyo dzisina kudzika;Kusimbisa panheyo murwi chivharo;Dzivirira geotextile membrane kubva pakubayiwa nevhu repasi;Dzivirira tsvina kana matombo mudhishi kubva pakubaya geomembrane;Nekuda kwekupokana kwakanyanya, zvinogona kutungamira kune kugadzikana kurinani kwemateru pacomposite geomembranes.
(3) Reverse kusefa
Pasi pechigadziko chedombo chakapwanyika chemugwagwa uye mugwagwa weairport kana pasi pechitima ballast;Yakapoteredza gravel drainage layer;Around underground perforated drainage pombi;Pasi penzvimbo yekurasira ivhu inoburitsa leachate;Dzivirirageotextilenetwork kudzivirira zvimedu zvevhu kubva pakupinda;Dzivirirageosyntheticzvinhu zvekudzivirira zvidimbu zvevhu kuti zvisapinde.
(4) Drainage
Seyakamira uye yakatwasuka drainage system yemadhamu evhu;Horizontal drainage ye pre yakatsikirirwa embankment pasi panheyo yakapfava;Sechivhariso chemvura yepasi pevhu capillary kukwira munzvimbo dzinonzwa chando;Capillary barrier layer yekuyerera kwesaline alkali solution munyika yakaoma;Sechigadziko chepasi che articulated concrete block slope protection.
