Fabricated Geomembrane Institute (FGI) ku yunivesite ya Illinois ku Urbana-Champaign inapereka Mphotho ziwiri za Fabricated Geomembrane Engineering Innovation Awards pamsonkhano wawo wazaka ziwiri womwe uli ku Houston, Texas, pa Feb. 12, 2019, pa Msonkhano wa Geosynthetics wa 2019.Mphotho yachiwiri, 2019 Engineering Innovation Award for Outstanding Fabricated Geomembrane Project, idaperekedwa kwa Hull & Associates Inc. chifukwa cha projekiti ya Montour Ash Landfill-Contact Water Basin.

Coal combustion Residuals (CCRs) ndi zinthu zomwe zimadza chifukwa cha kuyaka kwa malasha pamalo opangira magetsi omwe ali ndi makampani othandizira komanso opanga magetsi.Ma CCR nthawi zambiri amasungidwa m'malo otsekeka ngati matope onyowa kapena m'malo otayirapo ngati ma CCR owuma.Mtundu umodzi wa CCR, phulusa la ntchentche, ukhoza kugwiritsidwa ntchito mopindulitsa mu konkire.Nthawi zina, phulusa la ntchentche limatha kuchotsedwa m'madayi owuma kuti agwiritse ntchito bwino.Pokonzekera kukolola phulusa la ntchentche kuchokera pamalo otayirapo otsekedwa omwe analipo ku Montour Power Plant, beseni lamadzi lolumikizana linamangidwa mu 2018 kumunsi kwa dambo.Malo olumikizirana madzi adapangidwa kuti azitha kuyang'anira madzi olumikizana omwe amapangidwa pamene madzi olumikizana ndi madzi awuluka amawuluka phulusa panthawi yokolola.Chilolezo choyambirira cha beseni chinali ndi makina opangidwa ndi geosynthetic liner opangidwa kuchokera pansi mpaka pamwamba: gawo la engineering lomwe lili ndi underdrain system, geosynthetic clay liner (GCL), 60-mil textured high density polyethylene (HDPE) geomembrane, yopanda nsalu. khushoni geotextile, ndi wosanjikiza miyala yoteteza.

Hull & Associates Inc. ya ku Toledo, Ohio, inakonza mabeseni oti azitha kuyendetsa madzi osefukira omwe amayembekezeredwa kuchokera ku mphepo yamkuntho yazaka 25 kapena maola 24, komanso kusungirako kwakanthawi zinthu zilizonse zodzaza ndi zidole mkati mwa beseni.Asanamangidwe makina opangira makina ophatikizika, Owens Corning ndi CQA Solutions adalumikizana ndi Hull kuti apereke lingaliro la kugwiritsa ntchito RhinoMat Reinforced Composite Geomembrane (RCG) ngati chotchinga chinyezi pakati pa underdrain ndi GCL kuthandiza ntchito yomanga chifukwa cha mvula yambiri yomwe idagwa. zikuchitika m'dera.Pofuna kuwonetsetsa kuti mawonekedwe a RhinoMat ndi GCL sangabweretse chiwopsezo chokhazikika komanso kuti akwaniritse zofunikira, Hull adayambitsa kuyesa kumeta ubweya wa zinthuzo asanamangidwe.Mayesowa adawonetsa kuti zidazo zitha kukhala zokhazikika ndi 4H: 1V m'mbali mwa beseni.Mapangidwe a beseni lamadzi olumikizana ndi pafupifupi maekala 1.9 m'derali, okhala ndi 4H: 1V mbali zotsetsereka komanso kuya kwa pafupifupi mapazi 11.Kupanga kwa fakitale ya RhinoMat geomembrane kunapangitsa kuti mapanelo anayi apangidwe, atatu omwe anali ofanana kukula kwake, ndipo anali ndi masikweya mozungulira (mamita 160 170).Gulu lachinayi linapangidwa kukhala 120 mapazi 155 rectangle.Mapanelo adapangidwa kuti azitha kuyika bwino komanso momwe angatumizire kuti akhazikike mosavuta kutengera kasinthidwe ka beseni komwe akufuna komanso kuchepetsa kusoka ndi kuyesa.

Kuyika kwa RhinoMat geomembrane kunayamba pafupifupi 8: 00 am m'mawa wa July 21, 2018. Mapanelo onse anayi adayikidwa ndikuyikidwa muzitsulo za nangula masana pa tsikulo, pogwiritsa ntchito gulu la anthu a 11.Mvula yamkuntho ya mainchesi 0.5 inayamba pafupifupi 12:00 pm masanawa ndipo inaletsa kuwotcherera kulikonse kwa tsikulo.

Komabe, RhinoMat yomwe idatumizidwa idateteza gawo lopangidwa ndi injiniya, ndikuletsa kuwonongeka kwa dongosolo lomwe lidawonekera kale.Pa July 22, 2018, besenilo linali lodzaza pang’ono ndi mvula.Madzi amayenera kuponyedwa kuchokera m'beseni kuti atsimikize kuti m'mphepete mwake muli owuma kuti amalize nsonga zitatu zolumikizira.Misoko iyi ikamalizidwa, idayesedwa mosawononga, ndipo adayika nsapato kuzungulira mapaipi awiri olowera.Kuyika kwa RhinoMat kudamalizidwa masana pa Julayi 22, 2018, patatsala maola ochepa kuti mvula ichitike.

Sabata ya July 23, 2018, inabweretsa mvula yopitirira masentimita 11 ku Washingtonville, Pa., kudera la Washingtonville, Pa.Kuyika mwachangu kwa RhinoMat geomembrane yopangidwa pa Julayi 21 ndi 22 kunapereka chitetezo kwa malo opangidwa ndi injiniya ndi underdrain mu beseni, zomwe zikadawonongeka mpaka pakumanganso kofunikira, komanso kupitilira $100,000 pokonzanso.RhinoMat inapirira kugwa kwa mvula ndipo inagwira ntchito ngati chotchinga chinyezi chambiri mkati mwa chigawo cha liner cha kapangidwe ka beseni.Ichi ndi chitsanzo cha ubwino wapamwamba kwambiri ndi kutumizidwa mofulumira kwa ma geomembranes opangidwa ndi ma geomembranes opangidwa ndi ma geomembranes opangidwa angathandizire kuthetsa zovuta zomanga, komanso kukwaniritsa zolinga ndi zovomerezeka.
