Kugwiritsa Ntchito Geomembranes
Pamalo otayirako zinyalala omwe ndi ochezeka ndi chilengedwe: Masamba amtundu wa geotextile amatha kugwiritsidwa ntchito m'ma projekiti monga madambo a leachate ndi madzi amvula ndi zimbudzi zotsekera zimbudzi za malo otayiramo.
Zida za anti-seepage geomembrane zotayira zinyalala: HDPE yochuluka kwambiri # geomembrane #, zinthu za polima, mphamvu zambiri, moyo wautali wautumiki, komanso kutalika kwakukulu.
Mafotokozedwe apamwamba a polyethylene geomembrane: M'lifupi nthawi zambiri ndi 6m, ndipo makulidwe akhoza makonda pakati pa 0.1mm ndi 3.0mm.
Muyenera kudziwa cholinga cha geomembrane yofunika poyamba.Mitundu yosiyanasiyana ya geomembrane ili ndi katundu ndi makhalidwe osiyanasiyana, monga madzi, kupuma, kuzizira, kukalamba, ndi zina. Pokhapokha mutatsimikiza cholinga chomwe mungasankhe mankhwala oyenera.
Ma geomembranes amagawidwa m'magulu otsatirawa kutengera zinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito:
Membala wamba wa anti-seepage, nembanemba yakale yotsutsana ndi seepage (GB/T 17643-1998);
Mtundu watsopano wa anti-seepage membrane (GB/T17643-2011) GH-1 ndi GH-2S ndi wokonda zachilengedwe, pomwe nembanemba ya anti-seepage (CJ/T 234-2006) ili ndi ukadaulo wofananira ndi muyezo waku America. GM-13;
High density polyethylene geomembrane, monga chinthu chofunikira chotsutsana ndi ma geosynthetic, ndichofunikira pachitetezo cha chilengedwe komanso kudzipatula.M'mapulojekiti odana ndi chilengedwe, amalepheretsa madzi otayira ndi zinyalala kuti asalowe m'madzi apansi ndi kuipitsa.Itha kugwiritsidwanso ntchito pakuyika zigawo zosasunthika kuti madzi asalowemo.
Njira zopangira geomembrane:
Kukonzekera kugwirizana mkulu-kachulukidwe polyethylene geomembrane kwa kutayirapo malo: Musanayambe unsembe wa geomembrane, m'pofunika kuyeretsa malo yomanga kuonetsetsa yosalala pamwamba popanda protrusions kapena lakuthwa zinthu kupewa kuwononga geomembrane.
Masitepe oyika nembanemba ya geotextile: Yalani nembanemba ya geotextile pamalo omangapo, okhala ndi m'mphepete mwake pafupifupi 15cm, ndikukonzekera kulumikizana ndi makina owotcherera otentha otentha.
