Geotextile inonyanya kushandiswa kutsiva iyo yechinyakare granular zvinhu kuvaka inverted sefa uye muviri wemvura.Kana ichienzaniswa neyechinyakare inverted sefa uye muviri wemvura, ine hunhu hwehuremu huremu, kuenderera kwakanaka kwese, kuvaka kuri nyore, kusimba kwesimba, kurwisa ngura, kunaka kwekukura kwehutachiona hwehutachiona, hunyoro hunyoro, kubatana kwakanaka nevhu, kusimba kwepamusoro uye mamiriro ekunze. kuramba pasi pemvura kana muvhu, uye inoshamisa mashandiro ekushandisa Uye iyo geotextile inosanganawo nemamiriro ezvakajairwa inverted sefa zvinhu: 1 Kuchengetedza ivhu: kudzivirira kurasikirwa kwezvinhu zvevhu zvakachengetedzwa, zvichikonzera kuparara kwesepage, 2 Kupinda kwemvura: simbisa kuyerera kwemvura inoyerera. mvura, 3 Anti blocking pfuma: ona kuti haizovharirwe nevhu rakanaka.
Iyo geotextile ichapihwa chitupa chemhando yechigadzirwa kana ichinge yashandiswa, uye zviratidzo zvemuviri zvichayedzwa: misa pachikamu chechikamu, ukobvu, yakaenzana aperture, etc Mechanical indexes: simba rekusimba, kubvarura simba, simba rekubata, kuputika simba, kuputika. simba, kukweshana kwesimba rekubatana kwevhu, etc Zviratidzo zveHydraulic: vertical permeability coefficient, plane permeability coefficient, gradient ratio, etc Durability: kuchembera kuramba, kemikari kusaita ngura Muedzo uchaitwa nedhipatimendi rekuongorora zvemhando yepamusoro.Munguva yekuedzwa, zvinhu zvekuongorora zvakakodzera zvinogona kuwedzerwa kana kubviswa zvinoenderana nezvinodiwa zveprojekiti uye nezvinodiwa zvekuvaka, uye rondedzero yekuongorora yakadzama ichapihwa.
Munguva yekuisa geotextile, iyo yekubata kumeso inofanirwa kuchengetedzwa isina kujeka kusaenzana, matombo, midzi yemiti kana imwe tsvina inogona kukuvadza geotextile Kana uchiisa geotextile, haifanirwe kunge yakanyanya kusimba kudzivirira zvakanyanya deformation uye kubvaruka kweiyo geotextile panguva. kuvaka.Naizvozvo, zvinodikanwa kuchengetedza imwe mwero wekusimba.Kana zvichidikanwa, iyo geotextile inogona kuita kuti geotextile ive ne yunifomu kupeta Paunenge uchiisa geotextile: tanga waisa geotextile kubva kumusoro kwechikamu chekuputira zvichidzika, uye uiise bhuroka nebhuroka zvichienderana nenhamba.Upamhi hunopindirana pakati pemabhuroko i1m.Paunenge uchiisa musoro wakatenderera, nekuda kweiyo yepamusoro yakamanikana uye yakaderera yakafara, kutarisisa kwakanyanya kunofanirwa kubhadharwa kune yekuisa, nekungwarira kuvakwa kuchaitwa, uye hupamhi hwepamusoro pakati pemabhuroko huchasimbiswa. inofanirwa kubatwa nemazvo Kana tichiisa, isu tinofanirwa kuchengetedza kuenderera uye kusambopotsa kuisa Mushure mekunge geotextile yaiswa, haigone kuvhenekwa nezuva nekuti geotextile inogadzirwa nemakemikari fiber raw materials Kuvhenekerwa kwezuva kuchakuvadza simba, saka matanho ekudzivirira anofanira kunge ari. kutorwa.
Matanho edu ekudzivirira mukuvakwa kwe geotextile ndeaya: vhara geotextile yakavezwa nehuswa, iyo inovimbisa kuti geotextile haizooneswe nezuva, uye zvakare inoita basa riri nani mukudzivirira iyo geotextile yekuzovakwa kwematombo kwekupedzisira Kunyangwe kana iyo inodzivirira yehuswa mulch. inowedzerwa uye kugadzirwa kwematombo kunoitwa pane geotextile, iyo geotextile ichave yakanyatsochengetedzwa Uyezve, yakanakisa chirongwa chekuvaka ichasarudzwa nzira yekuvaka yematombo Nzira yedu yekuvaka ndeyekuti, nekuda kwehupamhi hwema mechanization yekuvaka. , dombo racho rinotakurwa nemarori emarara.Panguva yekuburutswa kwedombo, munhu akakosha anogadzwa kuti atungamire mota kuburitsa dombo, uye dombo rinoburutswa kunze kwemudzi wegedhi Iro bhuku rekufambisa tangi rinofanirwa kubatwa nekuchenjerera kudzivirira kukuvadza geotextile Kutanga, kukanda dombo rose pamwe chete. pasi pemugero we 0.5m.Panguva ino, vanhu vazhinji vanogona kukanda matombo pamwe chete nedombo pamusoro pechivharo zvakanyatsonaka.Mushure mokunge mugero wazara, fambisa matombo nemaoko nemukati wemukati wepasi dam foundation.Upamhi hwebwe hwakafanana neinodiwa nekugadzirwa.Ibwe rinofanira kusimudzwa zvakaenzana panguva yekuraswa kwebwe.Ibwe pamusoro pechivharo padivi pemutsetse wemukati hachizove chakanyanya kukwirira Kana yakanyanya kukwirira, haina kuchengetedzeka kune filament yakarukwa geotextile, uye inogona zvakare kutsvedza pasi, ichikonzera kukanganisa kune geotextile Naizvozvo, kutarisisa kwakanyanya kunofanirwa kubhadharwa.

① Dziviriro layer: ndiyo yekunze dhizaini inosangana nenyika yekunze.Yakagadzirirwa kuchengetedza kubva mukuyerera kwekunze kwekuyerera kwemvura kana masaisai, mamiriro ekunze uye kukukurwa kwevhu, kutonhora nekukuvadza mhete uye kudzivirira mwenje weultraviolet wezuva.Ukobvu hunowanzo 15-625px.
② Upper cushion: ndiyo nhanho yekuchinja pakati peyekudzivirira uye geomembrane.Sezvo chikamu chekudzivirira chiri kunyanya zvidimbu zvakakura zvezvinhu zvakashata uye zviri nyore kufamba, kana yakanyatsoiswa pa geomembrane, zviri nyore kukuvadza geomembrane.Nokudaro, mutsara wepamusoro unofanirwa kugadzirirwa zvakanaka.Kazhinji, kune jecha zvinhu zvematombo, uye ukobvu haufanire kunge uri pasi pe375px.
③ Geomembrane: ndiro dingindira rekudzivirira kudonha.Pamusoro pekudzivirira kwakavimbika kwekudzivirira, inofanirwawo kukwanisa kumira kumwe kushushikana kwekuvaka uye kusagadzikana kunokonzerwa nekugadziriswa kwemaitiro panguva yekushandiswa.Nokudaro, kunewo simba rinodiwa.Simba re geomembrane rakanangana nekukora kwayo, iyo inogona kutariswa kuburikidza ne theoretical calculation kana engineering ruzivo.
④ Lower cushion: yakaiswa pasi pe geomembrane, ine mabasa maviri: imwe ndeyekubvisa mvura uye gasi pasi pe membrane kuti ive nechokwadi chekugadzikana kwe geomembrane;imwe yacho ndeyekudzivirira geomembrane kubva pakukuvadzwa kwechitsigiro chekutsigira.
⑤ Chitsigiro chetsigiro: iyo geomembrane chinhu chinoshanduka, chinofanira kuiswa pane yakavimbika tsigiro layer, iyo inogona kuita geomembrane kushushikana zvakaenzana.
