Polankhula za udindo wa filimu ya pulasitiki muzitsulo zoteteza madzi komanso kutentha, choyamba tiyenera kuganizira za filimu yapadziko lapansi yosasunthika.Mtundu woterewu wa geomembrane ndiwotchuka chifukwa chakuchita bwino kwambiri ndipo utha kugwiritsidwa ntchito m'ma projekiti ambiri a madamu kapena ngalande.Mwinamwake tidzawona nsalu zopanda nsalu nthawi zambiri.Geomembrane kwenikweni ndi chinthu chachifupi cha fiber.
Geomembrane ikhoza kukulitsidwa kumlingo wina ndipo ingagwiritsidwe ntchito m'malo ambiri.Pambuyo pa geomembrane ikuphatikizidwa ndi filimu ya pulasitiki, timanena kuti khalidwe la filimu yoyambirira ya pulasitiki ikhoza kukonzedwa bwino, komanso ingathe kukwaniritsa zosowa zathu zambiri.Izi nthawi zambiri zimatchedwa geomembrane.Pamene zinthuzo zikuwonjezeredwa, mphamvu yotsutsana ya malo okhudzana ndi kukhudzana imatha kuwonjezeka, ndipo gawo lotetezera likhoza kupanga dziko lokhazikika.
Geomembrane ndi chinthu chachifupi chopangidwa ndi fiber
Kuphatikiza apo, geomembrane imatha kukana makina ena akunja amadzimadzi ndipo imakhala ndi kukana kwa dzimbiri.Ngakhale m'malo a asidi amphamvu, mitundu ina ya geomembrane imatha kusungidwa kwa nthawi yayitali.Nthawi zambiri, zida za geomembrane zimawopa kwambiri malo okhala acidic, amchere kapena amchere.Ngati mukufuna kugwiritsa ntchito mulch, ndi bwino kuziyika pamalo opanda dzuwa.
Chifukwa imatha kutalikitsa moyo wautumiki wa geomembrane ndikupewa zinthu zosungidwa zowala, mwa njira iyi yokha geomembrane ingapeweretu mankhwala.Kuwala kwa dzuwa kwa nthawi yayitali kumatha kukulitsa kutentha kwa geomembrane, motero kumapangitsa kuti geomembrane ikhale yosweka.Zingawonekere kuti pali kusiyana kwakukulu, koma kwenikweni, chikhalidwe cha geomembrane chasintha.
Ndi chitukuko cha zachuma, kugwiritsa ntchito geomembrane ndi geotextile ndikokulirakulira, komwe kumagwiritsidwa ntchito kwambiri pokonza malo, malo osungiramo zimbudzi, kuteteza madamu, ntchito zapansi panthaka ndi ntchito zina.Kodi pali kusiyana kotani pakati pa geomembrane ndi geotextile mukamagwiritsa ntchito geotextile?Tiyeni tione.
Ndiko kuti, makhalidwe osiyanasiyana:
1. Makhalidwe a geomembrane:
Geomembrane ndi mtundu wa zinthu zotsutsana ndi seepage zopangidwa ndi filimu yapulasitiki ndi nsalu zopanda nsalu.Kuchita kwa anti-seepage kwa zinthu zatsopano za geomembrane makamaka kumadalira machitidwe odana ndi seepage a filimu yapulasitiki.
1) Imalimbana kwambiri ndi kuwonongeka kwa chilengedwe komanso kuwonongeka kwa mankhwala.
2) Kutentha kwakukulu ndi moyo wautali wautumiki.
3) Anti-seepage ndi drainage system imayikidwa kuti igwire ntchito pamakina ndipo imakhala ndi ntchito zodzipatula komanso kulimbikitsa.
4) Mphamvu zophatikizika kwambiri, kulimba kwa peel komanso kukana kwabwino.
5) Kuchulukirachulukira kwamphamvu, kugundana kwakukulu komanso kocheperako kakang'ono kakukulitsa.
2. Zinthu za geotextile
Ma geotextiles, omwe amadziwikanso kuti geotextiles, ndi ma geosynthetics opangidwa ndi anthu opangidwa ndi ulusi wopangidwa ndi anthu, singano kapena malungo.Geotextile ndi mtundu watsopano wa geosynthetics.Chomalizidwa ndi nsalu, nthawi zambiri 4-6 mamita m'lifupi ndi 50-100 mamita kutalika.Ma geotextiles amagawidwa kukhala ma geotextiles ndi osaluka geotextiles.
1) Pakalipano, ulusi wopangidwa ndi geotextile umaphatikizapo ulusi wa polyamide, ulusi wa poliyesitala, ulusi wa polypropylene, ulusi wa polypropylene, ndi zina zotere, zonse zomwe zimakhala ndi maliro amphamvu komanso kukana dzimbiri.
2) Geotextile ndi mtundu wazinthu zomwe zimatha kulowa mkati zokhala ndi kusefa kwabwino komanso kudzipatula.
3) Nonwoven geotextile imakhala ndi ngalande zabwino chifukwa cha mawonekedwe ake opepuka.
4) Geotextile ili ndi kukana kwabwino kwa puncture, kotero imakhala ndi chitetezo chabwino.
5) Geotextile ili ndi friction coefficient yabwino komanso mphamvu yolimba, ndipo imakhala ndi magwiridwe antchito a geotextile reinforcement.
2 Kusiyanasiyana kwamadzi kupitilira:
Geomembrane ndi yosasunthika, pamene geotextile ndi yotheka.
3 Zida zosiyanasiyana:
Ma geomembrane ndi mbale za makulidwe osiyanasiyana opangidwa ndi utomoni wapamwamba kwambiri wa mamolekyulu kapena mphira potenthetsa extrusion kapena kuwomba.Iwo ndi nembanemba impermeable zopangidwa ndi mkulu ndi otsika kachulukidwe polyethylene, EVA, etc. Geotextiles ndi poliyesitala, akiliriki, etc. Non nsalu nsalu kukonzedwa ndi kupota, zovala khadi kapena makina nsalu nsalu, sanali nsalu nsalu kapena kupota, poliyesitala, polypropylene, akiliriki. fiber, nayiloni, etc.
4. Kusiyana kwa magwiridwe antchito:
Ma geotextiles ali ndi kusefa kwabwino, kukhetsa madzi, kudzipatula, kulimbikitsa, kuteteza ndi kuteteza masamba, ndipo ndi opepuka, olimba mwamphamvu, abwino mumlengalenga, kutentha kwambiri komanso kukana kukalamba.
Geomembrane ndi polima mankhwala flexible zinthu ndi pang'ono mphamvu yokoka, ductility wamphamvu, amphamvu mapindikidwe kusinthasintha, kukana dzimbiri, kutsika kutentha kukana ndi kukana chisanu.
Zolinga zosiyanasiyana:
Geotextiles amagwiritsidwa ntchito makamaka kulimbikitsa, kudzipatula, ngalande, kusefera ndi kuteteza.
Geomembrane imagwiritsidwa ntchito makamaka kusindikiza, kugawa, kupewa kutulutsa madzi komanso kupewa ming'alu.
