Yeyiphi eyona ndawo inde yomkhenkce ehlabathini?

owona mkhenkce omde

Abantu abaninzi bayazibuza yeyiphi eyona rink yomkhenkce inde ehlabathini. Ifumaneka e-Ottawa, eKhanada, i-"Rideau Canal Skateway" eyaziwayo ayiyona nje i-water canal elula, kodwa i-ice rink ende emhlabeni. Ngexesha lasebusika lifumana i-metamorphosis ephawulekayo, iguqulwa ibe yipaseji ebanzi yomkhenkce.

Kweli nqaku siza kukuxelela ukuba yeyiphi i-ice rink ende kunazo zonke emhlabeni, iimpawu zayo kunye nezisongelo zayo eziqhubekayo ngenxa yokutshintsha kwemozulu.

Ngowuphi owona mkhenkce omde ehlabathini?

Rideau Canal Skateway

Phantse iikhilomitha ezi-8 ezingaphazamisekiyo, ngokuzingca ibambe iwonga lelona nqanaba lide lokutyibiliza emhlabeni. Ukususela ngoJanuwari ukuya kuMatshi, amagunya asekuhlaleni akhutheleyo alungiselela kwaye aguqule le ndawo yoluntu, eqinisekisa ukufikeleleka kwayo ngokufakela iindlela ezilula zokungena kunye nefenitshala yesitrato.

Ukuqinisekisa ukusebenza kunye nokhuseleko lwale renki icocekileyo yomkhenkce, kunyanzelekile ukuba ubukhulu bomkhenkce bulingane ne-30cm. Le mfuneko ifuna ixesha eliphantse libe li-15 leentsuku ezilandelelanayo apho amaqondo obushushu aphakathi kwe -10 ºC kunye nama-20 ºC.

Ngaphakathi kulo mjelo womkhenkce kukho ingqokelela yeendawo ezichongiweyo ukonwabela ukutya okuswiti okanye ukuzifudumeza ngekomityi yetshokholethi eshushu. Ukongeza, kukho indawo eyaziwa ngokuba yi "Dunrobin Distilleries" ebonelela abantu abakwiminyaka esemthethweni ngokunikezela ngeziselo ezinxilisayo. Nabo bangaziqhelanisi ne-ice skating bangawonwabela amava ale ndawo. Banokuthatha uhambo okanye uhambo oluzolileyo bejikeleza iperiphery yerenki yokutyibiliza okanye ecaleni kwendlela enomda weRideau Canal, indawo eyamkelwa kwaye ikhuselwe yiUNESCO njengeNdawo yeLifa leMveli leHlabathi.

Iingxelo zasekhaya zibonisa ukuba iRideau Canal, indawo ethandwayo yabakhenkethi, iya kuhlala ivaliwe kulo lonke ixesha lobusika. Esi sisihlandlo sokuqala kwimbali yakutshanje ukuba iindwendwe aziyi kukwazi ukunandipha lo mmangaliso wendalo. Ubushushu obungaqhelekanga kunye nemozulu efumileyo iye yagquba kobu busika, ibangela ukuba amaqondo obushushu anyuke ngaphezu komndilili kwaye imvula inyuke. Ngenxa yoko, ezi meko zemozulu ziye zabangela ukuhla okuphawulekayo kobunzima kunye ne-porosity yomkhenkce, ngaloo ndlela ibeka esichengeni ukhuseleko lomjelo.

Ivaliwe ubusika obufudumeleyo

i-ice rink yendalo

Ngenxa yobusika obufudumeleyo nobumanzi ngokungaqhelekanga, iRideau Canal ayizukuvulwa kweli xesha lonyaka. Umkhenkce ogqume lo mjelo uncinci kakhulu kwaye uyangena ngakumbi xa kuthelekiswa neminyaka edlulileyo. Uvavanyo olubanzi ngabalawuli ziye zatyhila imikhenkce eyingozi engenakusetyenziswa luluntu. Oku kunokubalelwa kubusika bamva nje, obuyeyona ishushu e-Ottawa kumashumi eminyaka akutshanje, njengoko intwasahlobo iqala ngokusesikweni nge-1 kaMatshi. Ngaphezu koko, inani elibalulekileyo lekhephu eliwileyo (elidlula iimitha ezi-2) lenze ukuba kube nzima ukwenza umkhenkce otyebileyo kunye noguquguqukayo oyimfuneko kwiimeko ezifanelekileyo.

Ngokuchasene neenkolelo ezithandwayo, Ukuwa kwekhephu elinzima akuxhamli uzinzo lwe-ice rink. Ngokutsho kweengcali, ubunzima bekhephu bubangela ukuphambuka komkhenkce kwaye kwandisa ukungena kwamanzi ukuya phezulu ngeentanda, ekugqibeleni kunciphisa ukomelela komkhenkce.

Ubukho bekhephu ezibalulekileyo kunempembelelo embi ekuzinzeni komkhenkce, okubangela ukwanda kokungena kwamanzi kunye nokuphazamiseka. Unyaka ngamnye umthendeleko othi "Winterlude" uqhutyelwa kwikomkhulu, kodwa ngeli xesha ujongene nemeko eyahlukileyo. Ngenxa yeemeko ezikhankanywe ngaphambili, umthendeleko awukwazanga ukubanjelwa kwiCanal. Kumyalezo ekwabelwana ngawo kwi-Twitter, umphathi weCanal uvakalisa ukuphoxeka kwakhe ngokungakwazi ukuyivula kobu busika, nangona enze iinzame ezinkulu.

Ukulungiselela kunye nokuziqhelanisa nokutshintsha kwemozulu

eyona ndawo inde yomkhenkce ehlabathini

I-NCC, ngokubambisana neYunivesithi yaseCarleton, ihlola ngokusebenzayo kwaye ilungiselela iimpembelelo kunye neempembelelo zokutshintsha kwemozulu kumkhenkce. Ngokukodwa, bagxile kwiSkateway kunye nokuba sesichengeni kwayo kwiziphumo zokufudumala kwehlabathi. Ukongeza koku, iingcali kunye nabaphandi baye bachonga uxinzelelo oluninzi lwasezidolophini olujongene nerenki yokutyibiliza, njengokubaleka kwamanzi angaphezulu, ukungena kwetyuwa, kunye nobushushu obuphuma kwimibhobho engaphantsi komhlaba.

Kukho amayeza amaninzi anokuthi avele kolu phononongo: iinkanunu zodaka, i-ice probes, i-thermosyphons, okanye iindlela eziphuculweyo zokulawula umkhenkce. Ukumela uhlobo olutsha lotshintshiselwano lobushushu olusetyenziswa kwimimandla ye-Arctic, iithermosyphons zisebenza ngokuvumela umoya onomkhenkce ukuba ungene ngaphantsi kwesiseko sesakhiwo kwaye usasaze ubushushu kwindawo ephezulu. Ukusebenzisa obu bugcisa eSkateway kungaququzelela ukwanda komkhenkce ngokupholisa amanzi ngaphantsi komphezulu onomkhenkce.

Ubukhulu be 30 centimeters

Eyamkelwa yi-UNESCO njengeNdawo yeLifa leMveli yeHlabathi, indawo enkulu yomkhenkce yendalo ithatha ubude obunomtsalane be-7,8 km kwaye igubungela indawo egcinwe ngokucokisekileyo ye-165.621 km2, elilingana neerenki zokutyibiliza ezilingana ne-90 zeOlimpiki ezinobukhulu obungama-400 m inye.. Ubungakanani bayo obumangalisayo bufumene indawo kwi-Guinness Book of Records kwi-2005 njengeyona ndawo inkulu ye-ice rink kwiplanethi.

Ukuze umkhenkce ufikeleleke kuluntu ngokubanzi, kufuneka ufikelele kubukhulu obuziisentimitha ezingama-30. Le meko ihlangatyezwa xa amaqondo obushushu eguquguquka rhoqo phakathi kwe -10 kunye ne -20°C kangangeeveki ezimbini. Ngelishwa, uqikelelo lwemozulu lwangoku aluthembisi, njengoko amaqondo obushushu angekawehli nangaphantsi kwe-9°C kwiintsuku zamva nje.

Kwingxelo kwiThe Guardian, uClara Harman-Denhoed, umfundi, uvakalise ukuphoxeka kuzo zombini iinkampani nakubantu ngabanye, egxininisa ubukho obuzayo bokutshintsha kwemozulu. Ethetha ngolu luvo, uMphathiswa wezeNdalo waseCanada, uSteven Guilbeault, Uthe esi siganeko ngomnye umzekeliso wokutshintsha kwemozulu kweli lizwe.

Ukugcina umtsalane wale ndawo, iKomishoni yeNkunzi yeSizwe ithatha amanyathelo asebenzayo ngokuqalisa uthotho lwezifundo zokuziqhelanisa nemozulu, ngenjongo yokwandisa ubude kunye nokufumaneka komzila.

Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nokuba yeyiphi eyona rink ende yomkhenkce emhlabeni.
