Geotextile yekudhonza mvura

Tsananguro pfupi:

- Drainage geotextile rudzi rwezvinhu zve geosynthetic, izvo zvinonyanya kushandiswa muhurongwa hwekubvisa mvura muinjiniya yezvivakwa uye engineering ye geotechnical. Inogona kubvisa mvura kubva muvhu zvinobudirira uye zvakare kuita basa rekusefa uye kuparadzanisa. Inyanzvi yekugadzira inoshanda zvakawanda.

Ruzivo rweChigadzirwa

- Drainage geotextile rudzi rwezvinhu zve geosynthetic, izvo zvinonyanya kushandiswa muhurongwa hwekubvisa mvura muinjiniya yezvivakwa uye engineering ye geotechnical. Inogona kubvisa mvura kubva muvhu zvinobudirira uye zvakare kuita basa rekusefa uye kuparadzanisa. Inyanzvi yekugadzira inoshanda zvakawanda.

Nheyo yeKudhonza Mvura
- Kuyerera kwemvura kubva mugeotextile kunonyanya kuenderana nechimiro cheburi rayo uye kupindira kwayo. Kune maburi madiki akawanda mukati mayo, uye maburi aya akabatana kuti aumbe network yakaoma yemigero yekuyerera kwemvura.
- Kana mvura iri muvhu, pasi pesimba regiravhiti kana musiyano wekumanikidzwa (sekumanikidzwa kwemvura, kumanikidzwa kwekubuda kwemvura, nezvimwewo), mvura inopinda mukati me geotextile kuburikidza nemaburi e geotextile. Zvadaro, mvura inoyerera nemumigero yekudhonza mvura mukati me geotextile uye pakupedzisira inotungamirwa kunzvimbo yekubuditsa mvura, senge mapaipi ekudhonza mvura, zvirongo zvekudhonza mvura, nezvimwewo.
- Semuenzaniso, mu subgrade drainage system, mvura yepasi inopinda mu drainage geotextile pasi pesimba rekusiyana kwekumanikidzwa, uye mvura yacho inotakurwa kuenda kumapombi emvura ari padivi pemugwagwa kuburikidza ne geotextile, nokudaro ichiburitsa mvura iri pasi pe subgrade.

Hunhu hweKushanda
- Kushanda Kwemvura Yakachena
  - Geotextile yemvura ine mwero wepamusoro wekuyerera kwemvura uye inogona kuburitsa mvura nekukurumidza. Mwero wayo wekuyerera kwemvura unowanzo kuyerwa nemwero wepamusoro wekuyerera. Kana mwero wepamusoro wekuyerera kwemvura wakakura, kumhanya kwemvura kunokurumidza. Kazhinji, mwero wepamusoro wekuyerera kwemvura yemvura yegeotextile unogona kusvika pahukuru hwe10⁻² - 10⁻³ cm/s, izvo zvinoita kuti ikwanise kusangana nezvinodiwa zvakasiyana zvemvura.
  - Inogonawo kuchengetedza kushanda zvakanaka kwemvura inoyerera pasi pekumanikidzwa kwakati. Semuenzaniso, kana mugwagwa wakadzika pasi pemutoro wemotokari, geotextile yemvura inoyerera inogona kuramba ichiyerera zvakanaka uye haizovhari nzira dzemvura inoyerera nekuda kwekumanikidzwa.
- Kushanda Kwekusefa
  - Pakunoburitsa mvura, geotextile inoburitsa mvura inogona kusefa zvidimbu zvevhu zvinobudirira. Inogona kuvharira zvidimbu zvidiki (zvakaita sevhu, ivhu, nezvimwewo) zviri muvhu kuti zvisapinde mumigero yekubuditsa mvura uye kudzivirira nzira yekubuditsa mvura kuti isavhare. Kushanda kwayo mukusefa kunowanikwa nekudzora saizi yemaburi uye chimiro chemaburi egeotextile.
  - Kazhinji, saizi yepore yakaenzana (O₉₅) inoshandiswa kuyera mashandiro ekusefa kwegeotextile. Iyi parameter inomiririra kukosha kwakanyanya kwe95% yedhayamita yeparticle inogona kupfuura nepageotextile. Saizi yepore yakaenzana yakakodzera inogona kuve nechokwadi chekuti mvura nezvinhu zvakanyungudutswa mumvura chete ndizvo zvinogona kupfuura, ukuwo zvidimbu zvevhu zvichibatwa.
- Zvivakwa zveMichina
  - Geotextile yemvura ine simba rekudhonza uye simba rekudhonza uye inogona kutsungirira kudhonza uye kubvaruka panguva yekuvaka. Simba rekudhonza rinowanzova pakati pe1 - 10 kN/m, izvo zvinoita kuti isatyoke nyore panguva yekuisa nekushandisa.
  - Inoshanda zvakanaka pakudzivirira kuboorwa uye inogona kuramba kuboorwa kana ikasangana nezvinhu zvakapinza (senge matombo, midzi, nezvimwewo) uye kudzivirira kuparadzwa kwemigero yekudonhedza mvura.
- Kugara kwenguva refu uye Kuramba Kuora
  - Sezvo geotextile yemvura ichiwanzosangana nemamiriro akasiyana-siyana ekunze, inogara kwenguva refu. Nekukanganiswa nemwaranzi ye ultraviolet, shanduko yekupisa, kukurwa kwemakemikari nezvimwe zvinhu, inogona kuramba ichishanda zvakanaka.
  - Inotsungirira zvakanaka zvinhu zvakaita seasidhi nealkali, uye inogona kushanda zvakanaka ingave muvhu rine acid kana alkali. Semuenzaniso, muhurongwa hwemvura huri pasi pevhu hwepaki yemaindasitiri emakemikari, geotextile yemvura inogona kuramba kukanganiswa nemvura yakasviba yemakemikari uye kuona kuti nzira yemvura inoyerera inoramba ichishanda zvakanaka.

Maitiro Ekushandisa
- Uinjiniya hweMigwagwa neNjanji
  - Panyaya yekudhonza mvura pasi pevhu, geotextile yemvura inogona kuiswa pasi kana pamawere evhu kuti ibudise mvura yepasi pevhu nemvura pamusoro pemugwagwa. Izvi zvinobatsira kudzivirira kudhonza mvura pasi pevhu kubva kuzvirwere zvinokonzerwa nekuungana kwemvura, zvakaita sechando nekudzikira kwemvura.
  - Mukugadzira madziro ekuchengetedza migwagwa nenjanji, drainage geotextile inogona kushandiswa sesefa uye kuiswa kumashure kwemadziro ekuchengetedza madziro kuti ibudise mvura iri seri kwemadziro uye kudzivirira kurasikirwa kwevhu, zvichiita kuti madziro ekuchengetedza madziro agare akasimba.
- Uinjiniya hweKuchengetedza Mvura
  - Munzvimbo dzinoshandiswa mvura - dzimba dzinochengetedza mvura dzakadai semadhamu nemadhamu, dhamu remvura rinogona kushandiswa kuburitsa mvura inobuda mukati medhamu kana mudhamu, kuderedza kumanikidzwa kwemvura uye kugadzirisa kugadzikana kwechivako.
  - Murwizi - mahombekombe erwizi - injiniya yekudzivirira, drainage geotextile inogona kushandiswa senzira yekudhonza mvura uye sefa yekudurura mvura yakaungana mumativi erwizi uye kudzivirira ivhu remativi erwizi kuti risakukurwa nemvura yerwizi.
- Uinjiniya hwekuvaka
  - Munzvimbo dzisingapindi mvura uye dzinoburitsa mvura mudzimba dzepasi, nzvimbo dzinoyerera mvura dzinogona kushandiswa senzira yekuwedzera mvura pamwe chete nenzvimbo isingapindi mvura. Inogona kuburitsa mvura pasi pevhu rakatenderedza imba uye kudzivirira pasi kuti pasanyorove kana kuzara nemvura.
  - Mukugadzira madhiraivha emvura pasi penheyo, madhiraivha emvura anogona kuiswa pasi penheyo kuti abudise mvura pasi penheyo uye kuvandudza mamiriro ekumanikidzwa kwenheyo.
- Uinjiniya hweMarara
  - Pasi nepamawere emarara, nzvimbo dzinoshandiswa kuchera mvura dzinogona kushandiswa kuunganidza nekuburitsa mvura inobuda mumarara inobuda nekuora kwemarara. Izvi zvakakosha zvikuru pakudzivirira kubuda kwemarara uye kuchengetedza nharaunda.
  - Inogona zvakare kushandiswa pamwe chete nezvimwe zvinhu zve geotechnical (zvakadai se geomembranes) kugadzira nzira yekubvisa mvura yakawanda uye nzira inodzivirira kuyerera kwemvura kuti iparare marara.
