Ukuhlolwa kwesimo sika-Päiväkoti Konsti kuqediwe: isakhiwo sodonga lwangaphandle siyalungiswa endaweni

Njengengxenye yokunakekelwa kwezakhiwo zedolobha, ukuhlolwa kwesimo sayo yonke inkulisa i-Konsti sekuqediwe. Idolobha liphenye isimo sesakhiwo ngosizo lokuvuleka kwesakhiwo kanye namasampula, kanye nokuqapha isimo okuqhubekayo. Ngaphezu kwalokho, idolobha laphenya ngesimo sesimiso sokungenisa umoya kule ndawo. Uphenyo lwenziwa engxenyeni endala yenkulisa, ingxenye yokwandisa kanye nefulethi langaphambili lomlindi.

Ezifundweni zobunjiniyela bezakhiwo, ubumanzi bezakhiwo buhloliwe futhi isimo sazo zonke izingxenye zesakhiwo saphenywa ngokuvuleka kwesakhiwo, amasampula kanye nokuhlolwa kwe-tracer. Ngosizo lwezilinganiso zemvelo eziqhubekayo, izilinganiso zokucindezela kwesakhiwo uma kuqhathaniswa nomoya wangaphandle kanye nezimo zomoya wangaphakathi mayelana ne-carbon dioxide, izinga lokushisa kanye nomswakama kwaqashwa. Ukwengeza, ukugxilwa kwe-volatile organic compounds (VOC) emoyeni wasendlini kwalinganiswa futhi ukugxila kwemicu ye-mineral wool fibers kwahlolwa, futhi isimo sohlelo lokuphefumula umoya saphenywa.

Ophenyweni, umonakalo wendawo utholwe esakhiweni sodonga lwangaphandle lwe-terrarium engxenyeni endala yenkulisa, ezolungiswa ngo-2021. Izidingo zokulungisa ezincane zokuthuthukisa umoya wasendlini zitholwe esandisweni sesikhungo sokunakekela izingane kanye nasefulethini langaphambili lomnakekeli. Ezifundweni zokungenisa umoya, imithombo yefayibha yatholakala ohlelweni lokungena komoya, olwahogelwa ngemva kocwaningo. Ngemuva kokuhogela, idolobha liqinisekisa ukuthi yonke imithombo ye-fiber isusiwe ngesikhathi sokuhogela.

Okunye ukulungiswa okutholakala ekuhlolweni kwesimo kwenziwa ngokuhambisana neshejuli ngokuvumelana nohlelo lokulungisa nangaphakathi kwesabelomali. Lapho kuhlelwa futhi kulungiswa, ukulinyazwa kwezakhiwo kuyagwenywa futhi ukulungiswa okuthinta ukuphepha kokusebenzisa indawo kubekwa eqhulwini.

Isakhiwo sodonga sangaphandle sengxenye endala ye-terrarium siyalungiswa

Ingxenye endala, eyakhiwa ngo-1983, inesakhiwo esingaphansi komhlaba. Ukuhlolwa akuzange kubone noma yikuphi ukuvimbela amanzi endaweni engaphandle ye-plinth, futhi izilinganiso zomswakama zibonise umswakama owandayo esakhiweni saphansi endaweni yamaqembu amancane. Umswakama ukhuphukile emhlabathini ukhuphukela phezulu emigodini yezinto zokwakha, ikakhulukazi ezindaweni ezinqenqemeni zamathayili angaphansi kwesisekelo kanye nasezindaweni zokuhlukanisa kanye nokuvuleka kweminyango, kodwa ngokusho kwezifundo, akuzange konakalise ukumbozwa phansi. Uphenyo luthole umswakama ongavamile ngaphansi komata waphansi kusinki kwelinye lamagumbi eqembu lenkulisa, okungenzeka ukuthi kungenxa yokuvuza kokuxhunywa kukasinki.

"Indawo yokuvuza kukasinki egumbini leqembu kanye nesakhiwo saphansi sizolungiswa ngokwezinga elidingekayo ngokuhambisana neshejuli okuzovunyelwana ngayo nomsebenzisi osebenzisa indawo yenkulisa ngo-2021. Ngaphezu kwalokho, ngokohlelo lokulungisa, izakhiwo zaphansi endaweni yamaqembu amancane zizolungiswa kancane ngo-2023," kusho u-Ulla Lignell, uchwepheshe wezemvelo wasendlini wedolobha laseKerava.

Izindonga zangaphandle zengxenye endala ikakhulukazi ezakhiwe ngezitini zoboya-ngoboya, kodwa akukho ukukhula kwe-microbial okutholwe kumasampuli ngamanye athathwe ezakhiweni. Esikhundleni salokho, ukukhula kwe-microbial kwatholakala kusampula yokufakelwa ethathwe odongeni lwangaphandle lwamapulangwe lwe-terrarium, olwalufakwe uboya obunamaminerali. Amafasitela engxenye endala yesikhungo sokunakekela izingane ayesesimweni esihle kakhulu, kodwa amanye amafasitela ayeqhekeka, kanye nokungangenisi nokuxega emathinini amanzi. Ngosizo lokuhlolwa kwe-tracer okwenziwa njengengxenye yocwaningo, kutholwe ukuvuza komoya emalungeni esakhiwo. Ukwengeza, esakhiweni sesitezi esiphezulu sesakhiwo, ukushiyeka kwesakhiwo sokuvimbela umusi kanye nokushiyeka kwe-insulation yendawo kwabonwa endaweni ye-vestibule. Uphenyo luphinde lwathola nokushoda emithambekeni yezakhiwo ze-eaves kanye nasemiseleni yamanzi emvula ohlangothini olusenyakatho-mpumalanga yesakhiwo.

"Isakhiwo sodonga lwangaphandle lwe-terrarium sizolungiswa, isithiyo somoya sizovalwa futhi uboya obuvikelayo buzoshintshwa ngokuvumelana neshejuli okuzovunyelwana ngayo nomuntu osebenzisa indawo yenkulisa ngo-2021. Ukushiyeka kwasendaweni kwesakhiwo sesisekelo esiphezulu kuzophinde kulungiswe ngo-2021," kusho uLignell. "Ngaphezu kwalokho, imbobo yempande ye-antenna etholakala ezifundweni izokhishwa futhi noma yiziphi izinto ezilimele engxenyeni ephakathi kophahla lwamanzi zizovuselelwa ngokushesha ngangokunokwenzeka."

Izidingo zokulungisa ezincane ezithinta umoya wangaphakathi esandisweni nasefulethini lomnakekeli

Akukho umswakama otholiwe ezakhiweni ezingaphansi komhlaba ezingaphansi kwengxenye yokwandisa eyaqedwa ngo-2009, futhi isakhiwo se-plinth sesakhiwo sasingenamanzi ngekhilimu ye-bituminous. Isakhiwo sodonga sangaphandle sinesakhiwo sebhodi lesitini esivimbela umhwamuko, lapho kungekho monakalo we-microbial otholwe kumasampuli okufakwayo athathiwe. Izakhiwo zamafasitela zesandiso zisesimweni esihle futhi azikho iziphambeko ezitholakele kushidi wazo.

Ngosizo lokuhlolwa kwe-tracer okwenziwa njengengxenye yocwaningo, kutholwe ukuvuza komoya okuncane emalungeni esakhiwo. Izakhiwo zaphansi ezingaphezulu zengxenye enwetshiwe zazisesimweni esihle. Esakhiweni sesitezi esingaphezulu, akukho okungaphansi okutholwe ophenyweni, futhi kwakungekho mikhondo yomswakama endaweni engaphezulu.

“I-wool insulation yesitezi esiphezulu ifakwe kancane kancane, okubangela ibhuloho elibandayo kanye nengozi yokufingqa komswakama. Ngo-2021, ukufakwa koboya kuzofakwa kabusha kulawo maphuzu lapho ukufakwa bekungaphelele khona, ”kusho uLignell.

Akukho umswakama ongavamile otholakele esakhiweni sesitezi esingaphansi kwefulethi lomnakekeli wangaphambili, futhi akuzange kube khona umonakalo odalwe umswakama osembozweni waphansi. Ngaphezu kwalokho, izifundo azibonanga ukuvinjelwa kwamanzi esakhiweni se-plinth noma ukukhula kwe-microbial ku-insulation odongeni yangaphandle. Ngosizo lokuhlolwa kwe-tracer okwenziwa njengengxenye yocwaningo, kutholwe ukuvuza komoya emalungeni esakhiwo.

Isistimu yokukhipha umoya ihogelwe ngemva kokuhlolwa kwesimo

Akukho okungavamile okutholakele emiphumeleni ye-VOC yomoya wasendlini ezilinganisweni zemvelo eziqhubekayo. Ukugxila kwe-carbon dioxide nakho bekusezingeni elihle, nakuba ukugxila kuphakama isikhathi esifushane ekudlaleni nasezindaweni zokulala kokubili kwengxenye endala kanye nesandiso. Ukugxila kwe-mineral wool fiber bekungaphansi komkhawulo wesenzo, futhi akukho asbestos noma izinto zokwakha eziqukethe i-PAH ezitholwe kuhlolo lwezinto eziyingozi.

Imiphumela yezilinganiso zokushisa ezenziwe ngenkathi yasehlobo yayivamile ezakhiweni ezingenalo uhlelo lokupholisa. Ezilinganisweni zomehluko wengcindezi, izikhala zasendlini bezinokulinganisela noma zinengcindezi encane uma kuqhathaniswa nomoya wangaphandle, okuyisimo okuhlosiwe.

Ingxenye endala yendawo kanye nengxenye yokwelulwa inokungenisa umoya ngemishini kanye ne-exhaust ventilation, futhi imishini yayo yokungenisa umoya ivela ngesikhathi sokwakhiwa. Ngokujwayelekile ngesikhathi sokwakha, imishini yokungenisa umoya yengxenye endala kanye nendawo yekhishi isebenzise uboya bamaminerali ukuze kuthathwe umsindo.

"Imithombo yefiber ohlelweni lokungenisa umoya iyasuswa ngesikhathi sokuhogela okulandelayo, uma kungenzeka ngobuchwepheshe," kusho uLignell. "Iyunithi yokungenisa umoya engxenyeni endala isesimweni esihle kakhulu, kodwa indawo yokungenisa umoya ekhishini isesimweni esibi kakhulu sezingxenye zokungenisa umoya endaweni, ngoba cishe akunakwenzeka ukuyihlanza."

Ayikho imithombo yezintambo futhi asikho isidingo sokuhlanza esitholwe ohlelweni lokungena komoya lwengxenye yokwandisa. Azikho izidingo ezinkulu zokulungisa ezitholakele emishinini yokungenisa umoya futhi umthamo womoya wawuphakathi kwemingcele yamanani okuklama.

Ifulethi langaphambili lomnakekeli linomoya odonsela phansi. Izifundo zokungenisa umoya azizange zithole ama-valve omoya ashintshayo emafasiteleni noma izikhala zomoya ezishintshayo ezimpahleni zamafasitela. Ukungena komoya kwefulethi langaphambili lomnakekeli kuzothuthukiswa ngokungeza ama-valve omoya ashintshayo emafasiteleni ngo-2021.

Ngaphandle kwezifundo zesakhiwo kanye nokukhipha umoya, lesi sakhiwo siphinde senza ucwaningo lwemisele yokudonsa amanzi kanye nemigqa yamanzi emvula kanye namanzi angcolile, kanye nezifundo zesimo sezinhlelo zikagesi, imiphumela yazo esetshenziselwa ukuhlelwa kokulungiswa kwendawo.
