Munyika yekuvaka, kushandiswa kwezvinhu zvemhando yepamusoro kwakakosha pakugara kwenguva refu uye kubudirira kweprojekiti. Kana zvasvika pakudzikamisa ivhu uye mvura, geotextiles ndiyo mhinduro yesarudzo, inopa simba repamusoro uye kusimba. A special type ofgeotextileinonzi sefa jira iri kuwedzera mukurumbira nokuda kwayo yepamusoro kusefa zvinhu, zvichiita kuti zvinobudirira kudzora kuyerera kwemvura uye kudzivirira kukukurwa kwevhu.
Filtration jira ndeye yakasarudzika musiyano we geotextile yakagadzirirwa kusefa yakanaka zvimedu kubva mumvura. Inowanzoshandiswa mumhando dzakasiyana-siyana dzekuvaka dzakadai sekugadzira migwagwa uye njanji, kuchengetedza madziro, madhamu uye marara. Basa guru rejira iri nderokuparadzanisa zvikamu zvevhu uye kupa chigadziko chakagadzikana chezvimwe zvinhu zvekuvaka.
Iyo yakasarudzika dhizaini yesefa jirainobvumira mvura kupfuura nepo ichidzivirira kutama kwezvikamu zvevhu. Iyi filtration process inodzivirira kuvhara uye kuchengetedza iyo hydraulic kugona kweiyo geotechnical system, kuve nechokwadi chekuenderera kuyerera kwemvura. Machira emusefa anoita basa rakakosha mukusimudzira kusimba kwechimiro nekudzivirira kukukurwa kwevhu uye kuchengetedza mvura yakachena.
Kugona kusefa kwejira resefa kunonyanya kubatsira kune epasi pevhu drainage masisitimu. Kana matombo kana dombo rakapwanyika richishandiswa sehwaro, rinodzivirira kuvhara uye rinobvumira mvura kupfuura yakasununguka. Iyo nzira inovimbisa kuti mvura yakawandisa inobviswa zvinobudirira kubva mumigwagwa, minda uye dzimwe nzvimbo dzakavakwa, nekudaro ichikurudzira kugadzikana uye kudzivirira kukanganisa kunokonzerwa nemvura.
Kuwedzera kune madhiraivha masisitimu, machira esefa anowanzoshandiswa sezvipatsanuri pakati pezvikamu zvakasiyana zvevhu. Inoshanda sechipingamupinyi chekudzivirira kusanganiswa kwevhu rakaoma uye rakanaka-grained, kubvisa njodzi yekusiyana kwekugadzirisa. Kuzviparadzanisa uku hakusi kungowedzera kuvimbika kwechimiro cheprojekti yekuvaka, inodzivirirawo zvakatipoteredza nekudzivirira zvakasvibiswa kubva pakutamira muvhu.
Pakusarudza jira resefa, zvakakosha kuti utarise zvinhu zvakaita seyekuyerera, permeability, uye kusimba. Mapurojekiti akasiyana anoda zvirevo zvakasiyana, uye kubvunzana neane ruzivo geotechnical injiniya kunogona kubatsira kuona yakanakisa sefa jira kune chaiyo application.
Mukupedzisa, geotextiles, uye mafirita machira kunyanya, anochinja-chinja uye akakosha mhinduro mumapurojekiti ekuvaka. Iyo yepamusoro yekusefa masimba inoita kuti ive sarudzo yakavimbika yekudzikamisa ivhu, madhiraini masisitimu uye kuchengetedza kwezvakatipoteredza. Nekunyatso kudzora kuyerera kwemvura uye kudzivirira kukukurwa kwevhu, jira remasefa rinoita kuti hupenyu hurefu uye kubudirira kwezvirongwa zvekuvaka.
