iindaba

Ngomhla we-18 kuFebruwari, kumdlalo wamagqibela kankqoyi wokutyibiliza wabasetyhini omile okwe-U, uGu Ailing ufumene umndilili wamanqaku angaphezu kwama-90 kwimitsi emibini edlulileyo, etshixa ubuntshatsheli ngaphambi kwexesha kwaye waphumelela imbasa yegolide yesibhozo kubathunywa bezemidlalo baseTshayina.KwiGenting Ski Complex, iinqaba ezisithoba ezimhlophe qhwa zobukhulu obahlukeneyo kunye “namakhethini” amhlophe asibhozo ashicilelwe ngophawu lweeOlimpiki zaseBusika zazakhiwe ecaleni kwendlela yezakhono zasemoyeni kunye nezakhono zasemoyeni ezimilise u-U.Ezi "curtains" ezimhlophe ngokwenene yiminatha yomoya eyenziwe ngezinto eziphakamileyo ze-polyethylene, kungekhona nje ukuhlobisa okuhle, kodwa nokubonelela ngomqobo wokhuseleko kubadlali ukuba benze amaqhinga amangalisayo aphezulu.
Iumnatha ongenamoyaukukhusela iYunding ski resort complex yaphuhliswa ngokuzimeleyo liqela likaNjingalwazi uLiu Qingkuan, umlawuli weZiko loPhando lobuNjineli boMoya kwiYunivesithi yaseShijiazhuang Railway.Umnatha we-windbreak awuzange uqatshelwe ngazwinye kwaye udunyiswe kakhulu ziingcali ezifana ne-International Snow Federation, kodwa wafumana iindumiso ezininzi ezivela kubadlali abathatha inxaxheba ngexesha lokhuphiswano olusemthethweni.

“I-windscreen iyamangalisa, iyasikhusela emoyeni,” utshilo u-snowboarder wamadoda kunye nentshatsheli ye-Olimpiki yaseBusika izihlandlo ezithathu uSean White.“I-trackside net iyamangalisa,” utshilo umtyibilizi wase-American freestyle u-Megan Nick.I-windbreak isinceda kakhulu kwaye isigcina sizinzile naxa kukho umoya ovuthuzayo.”Umtyibilizi waseFreestyle uWinter Winecki ukwathe: “Kwiindawo ezininzi zokhuphiswano, iimbaleki kufuneka zikhuphisane nomoya.Kodwa apha, i-windscreen yenzelwe ukusigcina sikhuselekile kwaye isivumele ukuba sidlale amaqhinga ngakumbi emoyeni. "
NgokukaLiu Qingkuan, iqela lebala lemidlalo laseYunding kwindawo yokhuphiswano laseZhangjiakou linoxanduva lokhuphiswano lwe-skiing kunye nebhodi ekhephu.Olunye ukhuphiswano lwe-skiing luneemfuno ezingqongqo kakhulu emoyeni, ngokukodwa kwiziganeko ezibini zezakhono zasemoyeni kunye nezakhono ze-U-shaped field, apho iimbaleki zithatha khona Ukuphakama kukhulu, kwaye ezininzi iintshukumo ezinzima kufuneka zenziwe emoyeni.Ngaphantsi kwempembelelo yomoya onamandla, izakhono zinokukhubazeka kwaye ukusebenza kuya kuchaphazeleka, kwaye ibhalansi iya kulahleka emoyeni kwaye yenzakele.KwiiOlimpiki zaseBusika ezidlulileyo, ubuNtshatsheli beHlabathi kunye nolunye ukhuphiswano olubalulekileyo, kuye kwakho iingozi ezininzi apho iimbaleki zaphulukana nokulungelelana emoyeni ngenxa yemimoya ebhudla ngamandla kunye nokwenzakala.Ngoko ke, iFIS icebisa ukuba isantya somoya somzila kufuneka silawulwe ngaphantsi kwe-3.5 m/s ngexesha lokhuphiswano.
Ngaphambili, iminatha engangeni moya kwiindawo zokhuphiswano lokutyibilika ekhephini kwiiOlimpiki zaseBusika zonke zaveliswa zaze zafakwa ziinkampani zaseYurophu.Izinto ezenziweyo zazixabisa kakhulu, iingcaphulo zaziphezulu ngokwentelekiso, yaye ixesha lokwakha lalidla ixesha.Ngaphezu koko, ubhubhani wamazwe angaphandle wabangela ubunzima obuthile ekufumaneni.Ngoko ke, iiOlimpiki zaseBusika zangoku zazama ukusebenzisa iimveliso zasekhaya.Windscreen.Nangona kunjalo, akukho uyilo lwescreen somoya kunye nomenzi eTshayina onokuhlangabezana neemfuno zeFIS.Ekugqibeleni, iqela likaLiu Qingkuan lathatha umsebenzi wokuphuhlisa umnatha wokunqanda umoya.
NgokukaLiu Qingkuan, i-International Snow Federation ineemfuno ezingqongqo kwinani lezalathisi zenetha ye-windbreak kukhuphiswano lwe-ski, kwaye uyilo kufuneka lusekwe kwimpumelelo yokukhusela umoya, ukuhanjiswa kokukhanya, umbala, amandla kunye neminye imiba.Iqela leprojekthi liqale laqokelela iiparamitha ezahlukeneyo zesantya somoya ngexesha elinye leeOlimpiki zaseBusika kwiminyaka yakutshanje, emva koko lenze uhlalutyo lwemozulu, uvavanyo lomhlaba, kunye novavanyo lwetonela yomoya ukufumana idatha efana nobudlelwane obuhambelanayo phakathi kwezikhululo zemozulu ezikhoyo. kunye nesantya somoya kunye nesalathiso senqaku ngalinye kwindlela yeembaleki, kwaye emva koko UkuThatha indawo eyi-3.5 m/s njengento ekujoliswe kuyo, ukubalwa kwamanani ekhompyutha kunye novavanyo lwetonela yomoya lwaqhutywa ngokuphindaphindiweyo, kwaye ekugqibeleni kwagqitywa ukuba kusetyenziswe i-high- Ubuninzi bezinto eziphathekayo ze-polyethylene kunye nokuguquguquka okunamandla, kunye neeparamitha ezithile ze-high-density polyethylene windproof net zamiselwa.
Emva kokusombulula ingxaki yeparameter, isiphumo esibonwayo somnatha we-windbreak siba yingxaki kwakhona.Ukungeneka kwenethi yokuthintela umoya kuthelekiseka ngokuphambeneyo nesiphumo sokuthintela umoya.Ngokuphindaphindiweyo balinganisa imilinganiselo baza bafumana umenzi wesixhobo sokuluka umnatha esingangeni moya emazantsi.Sisebenzisa itekhnoloji yokuluka iinaliti ezili-12, siqulunqe ubume obunemigangatho emithathu yomoya odibana nefuthe lokuthintela umoya kunye neemfuno zokuhambisa ukukhanya.inethiwekhi.
U-Liu Qingkuan uthe i-high-density polyethylene windproof net imalunga ne-4 mm ubukhulu, kwaye isakhiwo sangaphakathi se-dimensional emithathu sinzima.Indibaniselwano yemingxuma ihlangabezana nje neemfuno zokusebenza ezimbini zomoya kunye nokuhanjiswa kokukhanya, kunye nokusebenza koxinzelelo phantsi komoya onamandla.Umnatha ongangenwa ngumoya unokumelana noxinzelelo lweetoni ezi-1.2 ngemitha yobubanzi, i-80% yomoya osuka ezantsi kumnatha ongummelwane unokuvaleka, kwaye isantya somoya esingaphezulu kwe-10 m/s sinokucuthwa siye kutsho kwi-3.5 m/s okanye ephantsi, eqinisekisa kakhulu ukhuseleko kunye nokuhamba kweembaleki zokugqiba.Inokumelana kakuhle nobushushu obuphantsi.Emva kokuphinda kukhenkceke kwaye kunyibilike kwi-40°C, kusenako ukuba nzima okanye kubhideke, kwaye kuhlala kugcine ukuguquguquka nokomelela.Ikwanayo ne-flame retardancy kunye nokuchasana kwe-UV ngexesha elifanayo, ixabiso aliphezulu, kwaye izikhombisi zezoqoqosho zilungile.Xa isetyenziswa, umnatha ongangeni moya unokuvulwa kwaye urhoxe kwinqaba phakathi kwemizuzu emi-6 ukuya kweyesi-8 ngokweemfuno zesiza, esinokusetyenziswa ngokuphindaphindiweyo.
Ukongeza, ukuze kuqinisekiswe ukuxhathisa ubushushu obuphantsi benkqubo yamandla oxinzelelo, isixhobo sokuqhuba sikwaxhotyiswe ngesixhobo sokufudumeza esikhawulezayo esisezantsi sokuqinisekisa ukuba ukuxinzelela kunye nokusebenza ngokutsha kungaqalwa ngokukhawuleza kubushushu obuphantsi.
Kumkhondo wezakhono zasemoyeni weGenting Ski Resort, uXu Mengtao kunye noQi Guangpu banikele ngeembasa zegolide ezimbini eTshayina ngokulandelelanayo, kwaye iqela elixubeneyo likaXu Mengtao, Qi Guangpu kunye neJia Zongyang liphumelele imbasa yesilivere;kukhuphiswano lwezakhono ezimilise u-U, uGu Ailing uphumelele imbasa yegolide.Impumelelo yezi ziphumo zibalaseleyo ayinakwahlulwa kwiinzame zabadlali kunye nesiqinisekiso seqela lenethi lokuqhawula umoya ngexesha lomdlalo.“Ngexesha loqeqesho lwesiqhelo kunye neendawo zokhuphiswano lwaphambi kokhuphiswano, iqela lethu lisoloko lisemsebenzini, libeka iliso kwisantya somoya, imilinganiselo yokulungiswa komphezulu wekhephu, ukuvulwa nokufunyanwa kweminatha yokunqanda umoya, ukudlula koosompempe kunye neenqwelo-mafutha ezenza ikhephu, njl. njl. iziphumo ezibalaseleyo zabadlali baseTshayina, nokuba inzima kangakanani na inkqubo,” utshilo uLiu Qingkuan ngokuzingca.
