Mu nthawi yomwe mapulojekiti oteteza zomangamanga ndi zachilengedwe akukumana ndi zofunikira kwambiri kuti zisalowerere, ma geomembrane amagwira ntchito ngati "zipangizo zofunika kwambiri zowongolera madzi"; magwiridwe antchito awo ndi kuyenerera kwawo kumatsimikizira mwachindunji chitetezo ndi ubwino wa chilengedwe wa pulojekiti. Pogwiritsa ntchito zaka zambiri zaukadaulo wosonkhanitsidwa komanso kafukufuku ndi chitukuko cha zochitika zinazake, Shandong Hongyue Environmental Engineering Co., Ltd. yawona zinthu zake za geomembrane zikugwiritsiridwa ntchito kwambiri m'magawo oposa khumi ndi awiri—kuphatikizapo kusamalira madzi, kuteteza chilengedwe, mayendedwe, ndi ulimi. Podziwika ndi "kusalowerera kwawo kwambiri, kukana nyengo, komanso kuyika kosavuta," zinthuzi zimapanga bwino "mzere woteteza pansi pa nthaka" wolimba wa mapulojekiti osiyanasiyana aukadaulo.
Mzere wa zinthu za geomembrane wa Shandong Hongyue Environmental umayang'ana kwambiri ma geomembrane a HDPE (High-Density Polyethylene), okhala ndi mitundu yosiyanasiyana monga ma nembanemba osalala, okhala ndi mawonekedwe, komanso ophatikizika. Ndi makulidwe a 0.2 mm mpaka 3.0 mm, zinthuzi zimagwirizana ndi muyezo wa dziko lonse wa GB/T17643-2011. Kuchuluka kwa madzi omwe amalowa m'nthaka kumafika 1 × 10⁻¹² cm/s—kofanana ndi kuchuluka kwa madzi olowa m'nthaka kwa ma milliliters 0.0001 okha pa sikweya sentimita pachaka—koposa kwambiri zofunikira zamakampani zowongolera madzi olowa m'nthaka. Kuphatikiza apo, zinthuzi zimaphatikizidwa ndi zinthu zotsutsana ndi ukalamba komanso zowonjezera zosagwira UV, zomwe zimathandiza kuti zinthu zizigwira ntchito bwino m'malo osiyanasiyana kuyambira -70°C mpaka 110°C. Zimasonyeza kukana kwambiri dzimbiri kuchokera ku ma acid ndi alkali okhuthala, zimakhala ndi mphamvu yokoka yoposa 18 MPa, ndipo zimatha kupirira mapangidwe ovuta a geological komanso nyengo yovuta.
Mu ntchito ya uinjiniya wa zachilengedwe, ma geomembrane amagwira ntchito ngati "chotchinga chachikulu pakuletsa ndi kuwongolera kuipitsidwa kwa madzi." Ma geomembrane a HDPE a Hongyue Environmental agwiritsidwa ntchito bwino m'mapulojekiti ambiri otayira zinyalala—kuphatikizapo Gawo Lachiwiri la Chifeng Central Urban Area Waste Treatment Center ndi Yueyang Domestic Waste Incineration Power Generation Project. Kudzera mu kapangidwe ka "membrane yosalowa madzi kawiri komanso ma geomembrane ophatikizika", machitidwe awa amaletsa kulowa kwa leachate ya zinyalala, motero amaletsa kuipitsidwa kwa nthaka ndi madzi apansi panthaka. M'mapulojekiti a malo oyeretsera madzi a zinyalala, ma geomembrane awa amagwiritsidwa ntchito pomanga maiwe osalowa madzi ndi zitsime zotayira madzi; kuyang'anira kotsatira komwe kumachitika kwa zaka zitatu kwawonetsa kuti palibe malo otayira madzi, motero kuchita gawo lofunikira pakuwonetsetsa kuti madzi a zinyalala oyeretsedwa akwaniritsa miyezo yoyendetsera kutulutsa madzi.
Uinjiniya wosamalira madzi ndi chimodzi mwa zinthu zofunika kwambiri pakugwiritsa ntchito ma geomembrane. Mu Yongtaichuan Irrigation Diversion and Storage Reservoir Project ku Jingtai County, Gansu Province, geomembrane ya HDPE yokhuthala 1.5mm yoperekedwa ndi Hongyue Environmental Protection idachita gawo lofunika kwambiri. Kudzera mu kapangidwe kake komwe kamagwiritsa ntchito "mawonekedwe apamwamba kuti akonze kukangana," nembanembayo imaletsa kutsetsereka m'malo otsetsereka a dziwe; nthawi yomweyo, mphamvu yake yayikulu yolimba imalola kuti igwirizane ndi maziko osalingana, potero kuonetsetsa kuti madzi osungiramo dziwe ali otetezeka komanso odalirika. Kuphatikiza apo, chinthuchi chagwiritsidwa ntchito bwino m'mapulojekiti ena osiyanasiyana, kuphatikiza zigawo zoletsa kusefukira kwa madzi za Eastern Route of the South-to-North Water Diversion Project ndi machitidwe oletsa kusefukira kwa madzi a Beijing-Shanghai High-Speed Railway. Mu ntchito zokhudzana ndi kukonzanso njira zamtsinje ndi kulimbitsa embankment, geomembrane imagwira ntchito ziwiri - kupereka mphamvu zoletsa kusefukira ndi kusefukira kumbuyo - motero kuchepetsa kukokoloka kwa nthaka ndikuwonjezera kukhazikika kwa polojekiti yonse.
Mu ntchito ya uinjiniya wa mayendedwe, ma geomembrane amagwira ntchito ngati "chishango choteteza" pamipanda ya misewu. Pakumanga misewu yayikulu ndi njanji, ma geomembrane a Hongyue Environmental Protection amagwiritsidwa ntchito ngati zigawo zoteteza madzi kuti zisalowe pansi kuti zisawonongeke ndi madzi apansi panthaka omwe amakwera, pomwe nthawi yomweyo amateteza ku kufewa kwa madzi apansi panthaka chifukwa cha kulowa kwa madzi amvula. Mu projekiti yokongoletsa malo ya Huanglong Expressway, ma geomembrane adagwiritsidwa ntchito limodzi ndi ma geotextiles; kugwiritsa ntchito kophatikizana kumeneku sikunangotsimikizira kukhazikika kwa kapangidwe ka subgrade komanso kunathandizira kutulutsa madzi kwa zomera zomwe zili pamwamba pake, potero kukwaniritsa zolinga ziwiri za "chitetezo cha uinjiniya ndi kukongola kwa chilengedwe."
Mu gawo la ulimi ndi ulimi wa nsomba, ma geomembranes aonekera ngati "chida champhamvu chochepetsera ndalama ndikuwonjezera magwiridwe antchito." Pomanga malo oberekera nkhumba 10,500 ku Tangyin, Henan Province, geomembrane yakuda ya HDPE ya Hongyue Environmental Protection yokwana 0.5mm idayikidwa kuti iteteze mpweya wa biogas kuti usalowe. Pogwiritsa ntchito kusinthasintha kwake kwabwino komanso kukana dzimbiri, nembanembayo imatsimikizira kusonkhanitsa bwino kwa biogas pomwe nthawi yomweyo imaletsa kutuluka kwa zinyalala za ziweto komanso kuipitsidwa kwa nthaka. Pantchito zaulimi wa nsomba, ma geomembranes amagwiritsidwa ntchito poteteza malo otsetsereka ndi pansi pa dziwe; kugwiritsa ntchito kumeneku kungachepetse kutayika kwa madzi ndi 30%, kuthandizira kupewa kufalikira kwa matenda a nsomba, komanso pomaliza pake kuthandiza alimi a nsomba kuwonjezera ndalama zawo.
Kupatula pa zochitika zomwe zatchulidwa pamwambapa, ma geomembrane a Hongyue Environmental Protection amagwiritsidwanso ntchito kwambiri m'magawo osiyanasiyana apadera, kuphatikiza machitidwe oletsa kutuluka kwa madzi m'madziwe a migodi, mipanda ya ngalande zapansi panthaka, ndi njira zotetezera madzi m'minda ya padenga. Kampaniyo imapereka ntchito zodula zomwe zimagwirizana ndi zofunikira za polojekitiyi ndipo imasunga gulu la akatswiri aukadaulo kuti lipereke chitsogozo chomanga pamalopo. Mwa kupereka ntchito yonse, kuyambira "kupereka zinthu" mpaka "chithandizo chaukadaulo" - Hongyue Environmental Protection imatsimikizira magwiridwe antchito abwino kwambiri oletsa kutuluka kwa madzi a polojekiti iliyonse yaukadaulo yomwe imathandizira. Pogwiritsa ntchito njira zawo zokhazikika komanso zofananira, zinthu za geomembrane za Shandong Hongyue Environmental Protection zafika m'mizinda yayikulu ndi yapakatikati yoposa 40 ku China, ndipo kutumiza kunja kufalikira kumadera monga Europe, America, ndi Australia. Popita patsogolo, pamene mapulojekiti oteteza zachilengedwe ndi zomangamanga akupitilira kupita patsogolo, Hongyue Environmental Protection ipitiliza kuyang'ana kwambiri pakusintha ukadaulo woletsa kulowa kwa madzi—kulimbitsa “mizere yoteteza pansi pa nthaka” pamapulojekiti ambiri—potero imathandizira chitukuko chogwirizana cha zomangamanga zobiriwira komanso kusunga zachilengedwe.
