IFabricated Geomembrane Institute (FGI) kwiDyunivesithi yase-Illinois e-Urbana-Champaign inikezele ngeeMbasa ezimbini zeFabricated Geomembrane Engineering Innovation ngexesha lentlanganiso yalo yaminyaka le emibini eHouston, eTexas, ngoFebruwari 12, 2019, kwiNkomfa ye-Geosynthetics ka-2019.Ibhaso lesibini, iMbasa yoBunjineli boBunjineli yowama-2019 yeProjekthi eBalaseleyo eyenziwe ngeGeomembrane, yanikezelwa kwi-Hull & Associates Inc. ngeprojekthi yeMontour Ash Landfill-Contact Water Basin.

IiNtsalela zokutshiswa kwamalahle (CCRs) ziimveliso zokutsha kwamalahle kumaziko ombane aphantsi kweenkampani eziluncedo kunye nabavelisi bamandla.Ii-CCR zihlala zigcinwa ngaphakathi kokuvalelwa komphezulu njengodaka olumanzi okanye kwiindawo zokulahla inkunkuma njengeeCCR ezomileyo.Olunye uhlobo lweCCR, i-fly ash, ingasetyenziselwa ukusetyenziswa okunenzuzo kwikhonkrithi.Kwezinye iimeko, uthuthu lwempukane lunokutsalwa kwiindawo zokugalela inkunkuma ezomileyo ukuze zisetyenziswe ngokuyingenelo.Ukulungiselela ukuvunwa kothuthu lwempukane kwitiphu esele ivaliwe kwi-Montour Power Plant, isitya sokudibanisa amanzi sakhiwa ngo-2018 emazantsi etiphu.Isitya samanzi adityanisiweyo sakhiwe ukuze silawule amanzi adityanisiweyo anokuthi aveliswe xa udibaniso lwamanzi angaphezulu luveze uthuthu lwempukane ngexesha lomsebenzi wokuvuna.Isicelo sokuqala semvume yesitya sokuhlambela sasiquka inkqubo yelayini ye-geosynthetic edityanisiweyo ebandakanya, ukusuka ezantsi ukuya phezulu: inqanaba lobunjineli elinenkqubo engaphantsi kwamanzi, i-geosynthetic clay liner (GCL), 60-mil textured high density polyethylene (HDPE) geomembrane, non-woven i-cushion geotextile, kunye nomgangatho wamatye okhuselayo.

I-Hull & Associates Inc. yase-Toledo, e-Ohio, ilungiselele uyilo lwesitya sokulawula ukubaleka kwamanzi okulindelekileyo kwisiganeko sesaqhwithi seminyaka engama-25/24, ngelixa ikwabonelela ngogcino lwexeshana lwayo nayiphi na imathiriyeli egcwele intlenga ngaphakathi kwesitya.Ngaphambi kokwakhiwa kwenkqubo ye-liner edibeneyo, i-Owens Corning kunye ne-CQA Solutions yaya ku-Hull ukuba iphakamise ukusetyenziswa kwe-RhinoMat Reinforced Composite Geomembrane (RCG) njengesithintelo sokufuma phakathi kwe-underdrain kunye ne-GCL ukunceda inkqubo yokwakha ngenxa yemvula enkulu eyayikho. ezenzeka kwindawo.Ukuqinisekisa ukuba ujongano lwe-RhinoMat kunye ne-GCL aluyi kubangela ukungqubana kojongano kunye nomngcipheko uzinzo lwethambeka kwaye luya kuhlangabezana neemfuno zemvume, i-Hull iqalise uvavanyo lokucheba kwilabhoratri yesixhobo ngaphambi kolwakhiwo.Uvavanyo lubonise ukuba izixhobo ziya kuzinza kunye ne-4H: 1V emacaleni e-basin.Uyilo lwesitya sokuqhagamshelana samanzi simalunga neehektare eziyi-1.9 kummandla, kunye ne-4H: 1V amathambeka asecaleni kunye nobunzulu obumalunga ne-11 yeenyawo.Ukwenziwa komzi-mveliso we-RhinoMat geomembrane kubangele ukuba kuyilwe iiphaneli ezine, ezintathu zazo bezinobukhulu obufanayo, kwaye zisikweri ngokwemilinganiselo (i-160 iinyawo 170 iinyawo).Iphaneli yesine yenzelwe i-120 foot 155 foot rectangle.Iiphaneli zenzelwe ukubekwa ngokufanelekileyo kunye nesikhokelo sokusasazwa ukuze kube lula ukufakela ngokusekwe kulungiselelo olucetywayo lwesitya kunye nokunciphisa ukuthungwa kwentsimi kunye novavanyo.

Ukufakwa kwe-RhinoMat geomembrane kwaqala malunga nentsimbi yesi-8:00 kusasa ngentsasa yomhla wama-21 kaJulayi 2018. Zone iiphaneli zasetyenziswa zaza zafakwa kwimisele ye-ankile ngaphambi kwemini emaqanda ngaloo mini, kusetyenziswa iqela labantu abali-11.Imvula eyi-0.5-intshi yaqalisa malunga nentsimbi ye-12:00 emva kwemini ngaloo mva kwemini yaza yathintela nayiphi na intsimbi eseleyo yolo suku.

Nangona kunjalo, i-RhinoMat esetyenzisiweyo ikhusele i-subgrade yobunjineli, kwaye ithintele umonakalo kwindlela engaphantsi kwe-underdrain evezwe ngaphambili.Ngomhla wama-22 kuJulayi 2018, isitya sasizele ngokuyinxenye yimvula.Kuye kwafuneka ukuba kumponthwe amanzi ukusuka kwisitya ukuze kuqinisekiswe ukuba imiphetho yephaneli yomile ngokwaneleyo ukuze kugqitywe imithungo emithathu yoqhagamshelo.Zakuba zigqityiwe ezi zithungo, zavavanywa ngendlela engonakalisiyo, kwaza kwafakelwa iibhutsi ezijikeleze imibhobho emibini yokungena.Ufakelo lwe-RhinoMat luthathwe lugqityiwe ngenjikalanga ye-22 kaJulayi, 2018, kwiiyure nje ezimbalwa phambi kwesiganeko esiyimbali semvula.

Iveki ye-23 kaJulayi 2018, yazisa ngaphezu kwee-intshi ze-11 zemvula kwindawo yaseWashingtonville, ePa., ebangela izikhukhula zembali kunye nomonakalo weendlela, iibhulorho kunye nezakhiwo zokulawula izikhukhula.Ufakelo olukhawulezileyo lwe-RhinoMat geomembrane eyenziweyo ngoJulayi 21 kunye ne-22 ibonelele ngokhuseleko kwi-subgrade yobunjineli kunye ne-underdrain kwi-basin, enokuthi ngenye indlela yonakaliswe kwinqanaba lokwakhiwa ngokutsha, kunye ne-100,000 yeedola ekusebenzeni kwakhona.I-RhinoMat imelana nemvula kwaye yasebenza njengesithintelo sokufuma esisebenza kakhulu ngaphakathi kwecandelo lelinen edibeneyo yoyilo lwesitya.Lo ngumzekelo weenzuzo zomgangatho ophezulu kunye nokuthunyelwa ngokukhawuleza kwee-geomembranes ezenziweyo kunye nendlela i-geomembranes eyenziwe ngayo inokunceda ukusombulula imingeni yokwakha, ngelixa ihlangabezana nenjongo yoyilo kunye neemfuno zemvume.
