Geomembrane inonyanya kushandiswa mumapurojekiti ekubvisa tsvina kubva mumarara, mapurojekiti emvura yemvura uye tsvina yetsvina.

Geomembrane, membrane yakagadzirwa nezvinhu zvepolymer, inoshandiswa munzvimbo dzakawanda, kunyanya mapurojekiti ekurasira marara anodzivirira kubuda kwemvura uye mvura yemvura uye tsvina, ine basa rayo rakanaka rekudzivirira mvura, kudzivirira kubuda kwemvura, kubvisa kunhuhwirira, kuunganidzwa kwebiogas, kudzivirira ngura uye hunhu hwekudzivirira kukwegura.

一. Hunhu hwepakutanga hwe geomembrane

Geomembrane chinhu chinodzivirira mvura chakavakirwa papolymer yakawanda yemamorekuru, polyethylene yakaderera (LDPE) Geomembrane, polyethylene yakawanda (HDPE) Geomembrane chinhu chine firimu ine simba rakawanda, inodzivirira ngura zvakanyanya, inodzivirira kukwegura zvakanyanya uye inodzivirira kubuda kwemvura. Chinhu chikuru chegeomembrane ndechekudzivirira kubuda kwemvura zvakanaka, izvo zvinogona kudzivirira kupinda kwemvura uye kudzivirira mvura yepasi nevhu kubva mukusvibiswa. Maitiro ekuvaka geomembrane ari nyore uye ari nyore kushandisa, izvo zvinogona kupfupisa nguva yekuvaka uye kuvandudza kushanda kwekuvaka. Inonyanya kushandiswa mumarara, nzvimbo yekuchengetera tsvina, nzira dzinodzivirira kubuda kwemvura, madhamu anodzivirira kubuda kwemvura uye subway engineering, nezvimwewo.

Kushandiswa kwegeomembrane mukudzivirira kubuda kwemarara

Mumapurojekiti ekuchengetedza nharaunda akadai senzvimbo dzekurasira marara, ma geomembrane, sezvikamu zvisingapindi mvura, anoita basa guru. Nekukurumidza kwekukura kwemaguta, kuraswa kwemarara kwave chikamu chakakosha chekutarisira maguta. Nzira dzechinyakare dzekurasira marara dzinowanzo kuve nenjodzi yekudonha kwemvura inosvibisa pasi pevhu nevhu, uye kushandiswa kwema geomembrane kunogadzirisa dambudziko iri zvinobudirira.

1. Kudzivirira kusvibiswa kwetsvina: Nekuisa ma geomembrane pasi uye kutenderedza dhaka, chidziviriro chakasimba chinodzivirira kunyura kwetsvina chinogadzirwa, icho chinodzivirira zvinobudirira kusvibiswa kwetsvina kuti isapinde mumvura yepasi nevhu uye inodzivirira kuchengetedzeka kwenharaunda yakapoteredza.
2. Kuvandudza kugadzikana kwenzvimbo yekurasira marara: Geomembrane haingoiti chete kuti irege kunyura, asiwo inovandudza kugadzikana kwenzvimbo yekurasira marara uye inodzivirira njodzi dzinogona kuitika dzakadai sekugara kwenheyo uye kudonha kwevhu kunokonzerwa nekuunganidzwa kwemvura inoyerera.
3. Deredza mari yekugadzirisa: Kushandiswa kwema geomembrane kunoderedza kudiwa kwekurapwa kwe leachate uye kunoderedza mari yekuchengetedza inotevera ukuwo kuchiwedzera hupenyu hwenzvimbo yekurasira marara.

Chimwe. Basa guru re geomembrane mumapurojekiti ekutsausa mvura yemvura uye tsvina yetsvina

Kubviswa kwemvura yemvura netsvina inzira yakakosha yekuvaka masisitimu emvura mumaguta, nechinangwa chekuunganidza, kutakura nekuchenesa mvura yemvura netsvina zvakasiyana kuti zvivandudze mashandisirwo akanaka ezviwanikwa zvemvura uye mamiriro enzvimbo yemvura. Geomembrane inoitawo basa guru muchirongwa ichi.

1. Kugona kuparadzanisa mvura yemvura netsvina zvinobudirira: Nekuisa ma geomembranes muzvikamu zvakakosha zvakaita sekutonga matangi, chikamu chekuparadzanisa pakati pemvura yemvura netsvina chinoumbwa kuitira kuti mvura yemvura isapinde mutsvina uye kuderedza mutoro wekugadzirisa tsvina nemitengo yekushandisa.
2. Kuvandudza hunhu hwemvura: Kushanda kwegeomembrane kunodzivirira kubuda kwemvura zvinobudirira kudzivirira zvinhu zvinokuvadza mutsvina kuti zvisapararire kunzvimbo dzakapoteredza, uye kunodzivirira kuchengetedzeka kwehunhu hwemvura yemvura yepasi pevhu.
3. Kugadzikana kwesisitimu kwakawedzerwa: Hunhu hwakasimba hwema geomembranes hunovabvumira kutsungirira migumisiro yechisikigo uye shanduko dzemamiriro ekunze, zvichiita kuti mvura yemvura uye masisitimu ekutsausa tsvina agare akasimba uye akavimbika.

Mafambiro ebudiriro yeramangwana

Nekuwedzera kweruzivo rwezvakatipoteredza uye kufambira mberi kwetekinoroji, kushandiswa kwema geomembranes mumarobho emarara anodzivirira kuyerera kwemvura uye mapurojekiti ekurasa mvura yemvura uye tsvina yetsvina kuchave kwakakura uye kwakadzama. Mune ramangwana, wedzera kushandiswa kwema geomembranes muminda yakawanda, yakadai sekudiridza kurima, kugadzirisa zvakatipoteredza, nezvimwewo, kuti ikurudzire kukura kwayo kumusika wakakura.

Mukupfupisa, ma geomembrane anoita basa guru mumabasa ekurasa marara asingasvibi mvura uye ekurasa mvura yemvura uye tsvina, pamwe chete nemabhenefiti awo akasiyana. Nekufambira mberi kwetekinoroji uye kuwedzera kwekushandiswa, ma geomembrane achaita basa rakakosha mukuchengetedzwa kwezvakatipoteredza mune ramangwana uye anobatsira mukuvaka nharaunda yemaguta ine girini uye inochengetedza nharaunda.
