Iyo Fabricated Geomembrane Institute (FGI) paYunivhesiti yeIllinois kuUrbana-Champaign yakapa maviri Fabricated Geomembrane Engineering Innovation Awards panguva yemusangano wayo wemakore maviri enhengo muHouston, Texas, Kukadzi 12, 2019, pa2019 Geosynthetics Musangano.Mubairo wechipiri, we 2019 Engineering Innovation Award for Outstanding Fabricated Geomembrane Project, wakaunzwa kuHull & Associates Inc. yeMontour Ash Landfill-Contact Water Basin project.

Coal combustion Residuals (CCRs) ndeye-zvigadzirwa zvekupisa kwemarasha pamagetsi emagetsi emakambani anoshanda nevagadziri vemagetsi.MaCCR anowanzo kuchengetwa mukati mekuvharirwa kwepasi sekunyorova slurry kana mumarara semaCCR akaoma.Imwe mhando yeCCR, inobhururuka madota, inogona kushandiswa kushandiswa kunobatsira mukongiri.Mune zvimwe zviitiko, madota enhunzi anogona kutorwa kubva mumarara akaoma kuti ashandiswe.Mukugadzirira kukohwewa kwedota renhunzi kubva padhishi rakavharwa riripo paMontour Power Plant, bheshi remvura rinosangana rakavakwa muna 2018 zasi kwerasira.Basin yemvura yekubatanidza yakagadzirwa kuti igadzirise mvura inosanganisirwa iyo yaizogadzirwa kana mvura yekumusoro yasangana inobuda madota enhunzi panguva yekukohwa.Chikumbiro chekutanga chemvumo yebheseni chaisanganisira inoumbwa geosynthetic liner system inosanganisira, kubva pasi kusvika kumusoro: yeinjiniya subgrade ine underdrain system, geosynthetic clay liner (GCL), 60-mil textured high density polyethylene (HDPE) geomembrane, isiri-yakarukwa. cushion geotextile, uye dombo rekudzivirira.

Hull & Associates Inc. yekuToledo, Ohio, yakagadzira dhizaini kuti igadzirise mafambiro aitarisirwa kubva muchiitiko chedutu chemakore makumi maviri nemashanu/maawa makumi maviri nemana, ukuwo ichipa kuchengetwa kwechinguvana kwechero dhaka rakaremerwa mukati mebheseni.Asati avakwa ecomposite liner system, Owens Corning neCQA Solutions vakaenda kuHull kuti vape zano rekushandisa RhinoMat Reinforced Composite Geomembrane (RCG) sechinhu chinodzivirira hunyoro pakati peiyo underdrain neGCL kuti ibatsire basa rekuvaka nekuda kwekunaya kwemvura kwakakura. kuitika munzvimbo.Kuona kuti iyo RhinoMat neGCL interface yaisazokonzeresa kukweshera uye kugadzikana kwengozi uye yaizozadzisa zvinodiwa nemvumo, Hull akatanga murabhoritari kuyerwa kwekugerwa kwezvinhu zvisati zvavakwa.Kuyedzwa kwacho kwakaratidza kuti zvinhu zvaizogadzikana ne4H: 1V mativi ebheseni.Dhizaini yedhizaini yemvura inosvika 1.9 maeka munzvimbo, ine 4H: 1V mativi akatenuka uye kudzika kunosvika gumi nerimwe tsoka.Kugadzirwa kwefekitari yeRhinoMat geomembrane kwakakonzera kuti mapanera mana agadzirwe, matatu aive akaenzana saizi, uye akaenzana masikweya muchimiro (160 tsoka 170 tsoka).Panera rechina rakagadzirwa kuita 120 tsoka 155 tsoka rectangle.Mapaneru akagadzirwa kuti anyatso kugadzika uye kutungamira kutungamira kuti zvive nyore kugadzika zvichienderana neyakarongwa bheseni kumisikidzwa uye kuderedza kusona kwemunda uye kuyedzwa.

Kuiswa kweRhinoMat geomembrane kwakatanga panguva dzinenge 8:00 am mangwanani eChikunguru 21, 2018. Mapaneli ese mana akaiswa uye akaiswa mumigero yeanchor masikati masikati pazuva iroro, vachishandisa boka revanhu gumi nemumwe.Dutu remvura 0.5-inch rakatanga nenguva dzinenge 12:00 pm masikati iwayo uye rakadzivirira chero welding zuva rose.

Nekudaro, iyo RhinoMat yakatumirwa yakadzivirira iyo mainjiniya, uye kudzivirira kukuvadzwa kune yakambofumurwa underdrain system.Musi waChikunguru 22, 2018, bheseni racho rakanga rakazara zvishoma nekunaya kwemvura.Mvura yaifanira kudhonzwa kubva mubheseni kuti ive nechokwadi chekuti mapanera aoma zvakakwana kuti apedze seam nhatu dzemunda.Pakangopera seam idzi, dzakaedzwa zvisingaite, uye bhutsu dzakaiswa dzakatenderedza pombi mbiri dzinopinza.Kuiswa kweRhinoMat kwakanzi kwapera masikati eChikunguru 22, 2018, maawa mashoma pamberi pechiitiko chekunaya kwemvura.

Vhiki yaChikunguru 23, 2018, yakaunza mvura inodarika 11 inches kuWashingtonville, Pa., nzvimbo, zvichikonzera mafashama enhoroondo uye kukanganisa kwemigwagwa, mabhiriji uye zvimiro zvekudzora mafashama.Kuiswa nekukasira kweiyo yakagadzirwa RhinoMat geomembrane musi waChikunguru 21 ne22 yakapa dziviriro kune yakagadziridzwa subgrade uye underdrain mubheseni, iyo ingadai yakakuvadzwa kusvika padanho rekuvakazve, uye inodarika $100,000 mukugadzirisa zvakare.Iyo RhinoMat yakamirisana nekunaya kwemvura uye yakashanda seyepamusoro-inoita hunyoro chipingamupinyi mukati meiyo composite liner chikamu chedhizaini dhizaini.Uyu muenzaniso wemabhenefiti emhando yepamusoro uye nekukurumidza kutumirwa kweakagadzirwa geomembranes uye magadzirirwo egeomembranes anogona kubatsira kugadzirisa matambudziko ekuvaka, ukuwo achisangana nechinangwa chekugadzira uye mvumo yemvumo.
