Kana tichitaura pamusoro pebasa refirimu repurasitiki mukuvharidzira kwemvura uye kupisa kwekushisa, tinofanira kutanga tafunga nezvepasi pasi firimu.Iri rudzi rwe geomembrane ine mukurumbira nekuita kwayo kwakanaka uye inogona kushandiswa mumapurojekiti mazhinji epasi madhamu kana migero.Zvichida tichaona machira asina kuruka muzviitiko zvakawanda.Geomembrane inongova pfupi fiber kemikari zvinhu.
Geomembrane inogona kuwedzerwa kusvika pamwero wakati uye inogona kushandiswa munzvimbo dzakawanda.Mushure mokunge geomembrane yakabatanidzwa nefirimu yepurasitiki, tinoti hutano hwepakutanga hwefirimu yepurasitiki inogona kunyatsogadziriswa, uye inogonawo kusangana nezvimwe zvatinoda.Nyaya iyi inowanzonzi geomembrane.Kana zvinhu zvacho zvawedzerwa, simba rekukwenya rekusangana kwepamusoro rinogona kuwedzerwa, uye chidziviriro chekudzivirira chinogona kuumba nyika yakagadzikana.
Geomembrane inonyanya ipfupi fiber kemikari zvinhu
Uye zvakare, iyo geomembrane inogona kuramba imwe yekunze kemikari maitiro ekuita uye ine yakanaka corrosion resistance.Kunyangwe munzvimbo yakasimba yeasidhi, mamwe maitiro e geomembrane anogona kuchengetedzwa kwenguva yakareba.Kazhinji kutaura, geomembrane zvinhu zvinotya zvakanyanya acidic, alkaline kana munyu nharaunda.Kana iwe uchida kushandisa mulch, zviri nani kuiisa munzvimbo isina zuva rakananga.
Nekuti inogona kurebesa hupenyu hwesevhisi yegeomembrane uye kudzivirira chiedza chakachengetwa zvinhu, nenzira iyi chete iyo geomembrane inogona kudzivirira kuita kwemakemikari.Nguva refu yezuva inogona kuwedzera tembiricha yepasi peiyo geomembrane, saka zvinozoita kuti chimiro chegeomembrane chitsemuke.Zvinogona kunge zvisingaoneki kuti pane musiyano mukuru, asi chaizvoizvo, chimiro che geomembrane chakachinja.
Nekuvandudzwa kwehupfumi, kushandiswa kwegeomembrane uye geotextile kwakawedzera uye kwakawedzera, kunyanya kushandiswa mukugadzira nzvimbo, sewage treatment plant, kudzivirira madhamu seepage, subway project nemamwe mapurojekiti.Ndeupi musiyano uripo pakati pe geomembrane uye geotextile kana uchishandisa geotextile?Ngatitarisei.
Ndiko, maitiro akasiyana:
1. Hunhu hwe geomembrane:
Geomembrane imhando yeanti-seepage zvinhu zvinoumbwa nefirimu repurasitiki uye jira risiri rakarukwa.Iyo anti-seepage performance yezvinhu zvitsva geomembrane inonyanya kuenderana ne-anti-seepage kuita kwefirimu repurasitiki.
1) Iyo ine yakanakisa kuramba kune kwezvakatipoteredza kusagadzikana kupaza uye kemikari corrosion.
2) Yakakura tembiricha renji uye hupenyu hurefu hwebasa.
3) Iyo anti-seepage uye drainage sisitimu yakagadzirirwa kuita pane yemuchina muviri uye ine mabasa ekuzviparadzanisa nevamwe nekusimbisa.
4) High composite simba, high peel simba uye yakanaka puncture kuramba.
5) Yakasimba yekudhonza mvura, hombe friction coefficient uye diki mutsara wekuwedzera coefficient.
2. Zvimiro zve geotextile
Geotextiles, anozivikanwawo sema geotextiles, anogoneka geosynthetics akagadzirwa neshinda dzakagadzirwa nevanhu, tsono kana mabraids.Geotextile rudzi rutsva rwe geosynthetics.Chigadzirwa chakapedzwa ijira, kazhinji 4-6 metres yakafara uye 50-100 metres kureba.Geotextiles yakakamurwa kuita geotextiles uye isiri-yakarukwa geotextiles.
1) Parizvino, mafiber ekugadzira anoshandiswa mukugadzira geotextile anonyanya kusanganisira polyamide fiber, polyester fiber, polypropylene fiber, polypropylene fiber, nezvimwe, izvo zvese zvine kuvigwa kwakasimba uye kusagadzikana kwekuora.
2) Geotextile imhando yezvinhu zvinopindika zvine zvakanaka kusefa uye mabasa ekuzviparadzanisa nevamwe.
3) Nonwoven geotextile ine yakanaka dhiraivha kuita nekuda kweiyo fluffy chimiro.
4) Geotextile ine yakanaka puncture kuramba, saka ine yakanaka kuchengetedza kuita.
5) Geotextile ine yakanaka friction coefficient uye tensile simba, uye ine kuita kwe geotextile kusimbisa.
2 Kusiyana kwemvura kupinza:
Geomembrane haipindike, nepo geotextile inopindika.
3 Zvinhu zvakasiyana:
Geomembranes mahwendefa ehukobvu hwakasiyana akagadzirwa neakakwira molecular resin kana rabha nekudziisa extrusion kana blow molding.Iwo mamembrane asingapindiki akagadzirwa nepamusoro uye yakaderera density polyethylene, EVA, etc. Geotextiles ipolyester, acrylic, etc. Machira asina kurukwa anogadzirwa nekuruka, zvipfeko zvekadhi kana machira akarukwa nemuchina, machira asiri akarukwa kana kuruka, polyester, polypropylene, acrylic. fiber, naironi, nezvimwewo.
4. Musiyano wekuita:
Geotextiles ane kusefa kwakanaka, kudhiraivha, kuzviparadzanisa nevamwe, kusimbisa, kudzivirira kudonha uye kuchengetedza mabasa, uye ane huremu huremu, akakwira mukusimba kwesimba, akanaka mumhepo permeability, yakakwirira mukupisa uye kuramba kuchembera.
Geomembrane ipolymer kemikari inochinjika zvinhu ine diki chaiyo giravhiti, yakasimba ductility, yakasimba deformation inochinjika, corrosion resistance, kushomeka kwekushisa uye kumira kwakanaka kwechando.
Zvinangwa zvakasiyana:
Geotextiles anonyanya kushandiswa kusimbisa, kuzviparadzanisa nevamwe, kudhiraivha, kusefa uye kudzivirira.
Geomembrane inonyanya kushandiswa kuisa chisimbiso, kupatsanura, kudzivirira seepage uye kudzivirira kuparuka.
