I-Fabricated Geomembrane Institute (FGI) eNyuvesi yase-Illinois e-Urbana-Champaign yethule Imiklomelo emibili Ye-Fabricated Geomembrane Engineering Innovation phakathi nomhlangano wayo waminyaka yonke wobulungu e-Houston, e-Texas, ngo-Feb. 12, 2019, eNgqungqutheleni ye-Geosynthetics ka-2019.Umklomelo wesibili, i-2019 Engineering Innovation Award for Outstanding Fabricated Geomembrane Project, yanikezwa i-Hull & Associates Inc. ngephrojekthi ye-Montour Ash Landfill-Contact Water Basin.

I-Coal combustion Residuals (CCRs) iwumkhiqizo wokushiswa kwamalahle ezimbonini zikagesi eziphethwe yizinkampani ezisizayo kanye nabakhiqizi bamandla.Ama-CCR ngokuvamile agcinwa ngaphakathi kokuvinjelwa okungaphezulu njengodaka olumanzi noma ezindaweni zokulahla phansi njengama-CCR omile.Olunye uhlobo lwe-CCR, umlotha wempukane, lungasetshenziselwa ukusetshenziswa okunenzuzo kukhonkolo.Kwezinye izimo, umlotha wempukane ungase ukhishwe ezindaweni zokulahla imfucumfucu ezomile ukuze zisetshenziswe ngokunenzuzo.Ukulungiselela ukuvunwa komlotha wezimpukane endaweni yokulahla imfucumfucu evaliwe e-Montour Power Plant, kwakhiwa umgodi wokuxhuma amanzi ngo-2018 ezansi nomfula.Isitsha samanzi okuthintana naye sakhiwe ukuze kulawuleke amanzi okuthintana azokhiqizwa lapho amanzi angaphezulu evezwa umlotha wempukane ngesikhathi sokuvuna.Isicelo sokuqala semvume yomcengezi sasihlanganisa isistimu ye-geosynthetic liner eyinhlanganisela ehlanganisa, ukusuka phansi kuye phezulu: i-subgrade yobunjiniyela enesistimu ye-underdrain, i-geosynthetic clay liner (GCL), 60-mil textured high density polyethylene (HDPE) geomembrane, non-woven. i-cushion geotextile, kanye nongqimba lwamatshe oluvikelayo.

I-Hull & Associates Inc. yase-Toledo, e-Ohio, ilungise idizayini yokugezela ukuze kulawuleke ukugeleza okulindeleke kusukela emcimbini wesiphepho esithatha iminyaka engama-25/amahora angu-24, kuyilapho futhi ihlinzeka ngokugcinwa kwesikhashana kwanoma iyiphi impahla egcwele inzika ngaphakathi komcengezi.Ngaphambi kokwakhiwa kwesistimu ye-liner eyinhlanganisela, u-Owens Corning kanye ne-CQA Solutions bathintana nabakwa-Hull ukuze baphakamise ukusetshenziswa kwe-RhinoMat Reinforced Composite Geomembrane (RCG) njengesithiyo somswakama phakathi kwe-underdrain ne-GCL ukusiza inqubo yokwakha ngenxa yemvula enkulu eyayikhona. okwenzeka endaweni.Ukuze kuqinisekiswe ukuthi i-interface ye-RhinoMat ne-GCL ngeke idale ukungqubuzana kokusebenzelana nobungozi bokuqina kwemithambeka futhi izohlangabezana nezimfuneko zemvume, i-Hull iqale ukuhlola ukugunda kweselabhorethri kwento ngaphambi kokwakhiwa.Ukuhlola kubonise ukuthi izinto ezisetshenziswayo zizozinza nge-4H:1V eseceleni kwe-basin.Idizayini yokugeza amanzi okuthintana nayo icishe ibe amahektha angu-1.9 endaweni, enezindawo eziseceleni ezingu-4H:1V kanye nokujula okungamafidi angu-11.Ukwakhiwa kwefekthri kwe-RhinoMat geomembrane kuholele ekudalweni kwamaphaneli amane, amathathu awo anosayizi ofanayo, futhi anomumo oyisikwele (amafidi angu-160 namafidi angu-170).Iphaneli yesine yakhiwe yaba unxande ongu-120 foot 155 foot.Amaphaneli aklanyelwe ukubekwa okufanelekile kanye nesiqondiso sokuphakelwa ukuze kube lula ukufakwa ngokusekelwe ekucushweni komcengezi okuhlongozwayo kanye nokunciphisa ukuthungwa kwenkundla nokuhlola.

Ukufakwa kwe-geomembrane ye-RhinoMat kuqale cishe ngo-8:00 ekuseni ekuseni ngomhla ka-Julayi 21, 2018. Wonke amaphaneli amane asetshenziswa futhi afakwa emiseleni okusetshenzwa kuyo ngaphambi kwehora leshumi nambili emini ngalolo suku, kusetshenziswa ithimba labantu abangu-11.Isiphepho esingamayintshi angu-0.5 saqala cishe ngo-12:00 ntambama ngaleyo ntambama futhi savimbela noma yikuphi ukushisela ngalolo suku lonke.

Kodwa-ke, i-RhinoMat esetshenzisiwe ivikele i-subgrade enjiniyela, futhi yavimbela ukulimala ohlelweni olungaphansi oludalulwe ngaphambilini.Ngomhla zingama-22 kuJulayi, 2018, isigodi sasigcwele ingxenye yemvula.Amanzi kwakudingeka amponthwe kusuka kumcengezi ukuze kuqinisekiswe ukuthi amaphethelo ephaneli ayomile ngokwanele ukuze aqedele imithungo yenkundla yokuxhuma.Lapho le mithungo isiqediwe, yavivinywa ngendlela engonakalisi, futhi kwafakwa amabhuzu eduze kwamapayipi amabili angenayo.Ukufakwa kwe-RhinoMat kuthathwe njengokuqediwe ntambama zingama-22 kuJulayi, 2018, amahora ambalwa nje ngaphambi komcimbi oyingqopha-mlando wokuna kwemvula.

Isonto langomhla zingama-23 kuJulayi 2018, laletha imvula engaphezu kwama-intshi angu-11 endaweni yase-Washingtonville, Pa.,, okubangele izikhukhula ezinomlando nokulimala kwemigwaqo, amabhuloho nezakhiwo zokulawula izikhukhula.Ukufakwa ngokushesha kwe-RhinoMat geomembrane ekhiqiziwe ngoJulayi 21 no-22 kunikeze isivikelo endaweni engaphansi eyenziwe ngobunjiniyela kanye ne-underdrain esitsheni, ebesiyolimala kuze kube seqophelweni lokwakhiwa kabusha okudingekayo, kanye nangaphezulu kuka-$100,000 wokusebenza kabusha.I-RhinoMat yakwazi ukumelana nemvula futhi yasebenza njengesithiyo somswakama esisebenza kahle kakhulu ngaphakathi kwengxenye yomugqa oyinhlanganisela yedizayini yesitsha.Lesi isibonelo sezinzuzo zekhwalithi ephezulu kanye nokusatshalaliswa okusheshayo kwama-geomembranes akhiwe nokuthi ama-geomembranes akhiwe angasiza kanjani ukuxazulula izinselele zokwakha, kuyilapho ehlangabezana nezinhloso zomklamo nezimvume.
