Geomembrane ya kompositi imagwiritsidwa ntchito kwambiri muukadaulo woletsa ngalande.M'zaka zaposachedwa, kugwiritsiridwa ntchito kwakukulu ndi mphamvu ya deta ya geotechnical decomposition mu engineering civil, makamaka pakuwongolera kusefukira kwa madzi ndi ntchito zopulumutsira mwadzidzidzi, kwachititsa chidwi kwambiri ndi akatswiri odziwa zaumisiri.Ponena za njira zogwiritsira ntchito zidziwitso zakuwola kwa geotechnical, boma lapereka njira zokhazikika zopewera kusefera, kusefera, kukhetsa madzi, kulimbitsa, ndi chitetezo, zomwe zikufulumizitsa kwambiri kukweza ndi kugwiritsa ntchito deta yatsopano.Izi zakhala zikugwiritsidwa ntchito kwambiri m'mapulojekiti oteteza ngalande m'madera othirira.Kutengera chiphunzitso cha zomangamanga pamodzi, pepalali likukamba za njira zogwiritsira ntchito geomembrane yophatikizika.

Composite geomembrane ndi gulu la geomembrane lopangidwa ndi kutentha mbali imodzi kapena zonse za nembanemba mu uvuni wa infrared, kukanikiza geotextile ndi geomembrane palimodzi kudzera pa chogudubuza chowongolera.Ndi kupita patsogolo kwaukadaulo wantchito, palinso njira ina yopangira geomembrane yamagulu.Mkhalidwewu umaphatikizapo nsalu imodzi ndi filimu imodzi, nsalu ziwiri ndi filimu imodzi, ndi filimu ziwiri ndi nsalu imodzi.
Monga gawo loteteza la geomembrane, geotextile imalepheretsa wosanjikiza woteteza komanso wosasunthika kuti usawonongeke.Kuti muchepetse cheza cha ultraviolet ndikuwonjezera magwiridwe antchito, ndikofunikira kugwiritsa ntchito njira yoyikira.
Pomanga, choyamba gwiritsani ntchito mchenga kapena dongo lokhala ndi mainchesi ang'onoang'ono kuti muwongole maziko a maziko, ndiyeno ikani geomembrane.Geomembrane sayenera kutambasulidwa mwamphamvu kwambiri, mbali zonse ziwiri zokwiriridwa m'nthaka mumpangidwe wamalata.Pomaliza, gwiritsani ntchito mchenga kapena dongo kuti muyale mtunda wa 10cm pa geomembrane yoyalapo.Mangani miyala ya 20-30cm (kapena midadada ya konkire) ngati yotchinga kuti isakokoloke.Pakumanga, kuyesayesa kuyenera kuchitidwa kuti miyala isamenye molakwika geomembrane, makamaka kuyimitsa kumanga kwa chishango ndikuyika nembanemba.Kulumikizana pakati pa geomembrane yophatikizika ndi zozungulira zozungulira kuyenera kulumikizidwa ndi mabawuti ocheperako ndi mikanda yachitsulo, ndipo cholumikiziracho chiyenera kuphimbidwa ndi emulsified asphalt (2mm wandiweyani) kuti amangirire kuti asatayike.
Chochitika chomanga
(1) Mtundu wokwiriridwa uyenera kutengedwa kuti ugwiritsidwe ntchito: makulidwe ophimba asakhale ochepera 30cm.
(2) Dongosolo lokonzedwanso la anti-seepage liyenera kukhala ndi khushoni, anti-seepage layer, transition layer, ndi chishango.
(3) Nthaka iyenera kukhala yofewa kuti ipewe kukhazikika kosagwirizana ndi ming'alu, ndipo turf ndi mizu yamitengo yomwe ili m'malo osalowererapo iyenera kuchotsedwa.Ikani mchenga kapena dongo lokhala ndi tinthu tating'onoting'ono ngati malo oteteza pamwamba pa nembanemba.
(4) Poyala, geomembrane sayenera kukoka mwamphamvu kwambiri.Ndi bwino kuti muyike malekezero onse mu nthaka corrugated mawonekedwe.Kuonjezera apo, pogwirizanitsa ndi deta yolimba, kuwonjezereka kwina ndi kutsika kuyenera kusungidwa.
(5) Pakumanga, ndikofunikira kuteteza miyala ndi zinthu zolemetsa kuti zisamenye molakwika geomembrane, kupanga ndikuyika nembanemba, ndikuphimba gawo loteteza.
