Iindaba - Ukuzivelela koLwakhiwo lwe-Olimpikhi oluBalekayo loMphezulu

Imbali yeIingoma ezibalekayo zeOlimpikiibonisa iindlela ezibanzi kubuchwepheshe bezemidlalo, ulwakhiwo, kunye nezixhobo. Nalu ujongo oluneenkcukacha ngendaleko yabo:

Iingoma ezibalekayo zeOlimpiki cinder topolyurethane

IiOlimpiki zamandulo

- Iingoma zamandulo (malunga nowama-776 BC):IMidlalo yeOlimpiki yantlandlolo eyayibanjelwe eOlympia, eGrisi, yayinomdlalo omnye obizwa ngokuba lugqatso lwestadion, malunga neemitha ezili-192 ubude. Umzila wawulula, umendo wokungcola othe tye.

IiOlimpiki zanamhlanje

Ngo-1896 iiOlimpiki zaseAthene:IMidlalo yeOlimpiki yokuqala yanamhlanje ibonise umzila wokugijima kwi-Panathenaic Stadium, umzila ochanekileyo weemitha ze-333.33 ezenziwe ngamatye atyunyuziweyo kunye nesanti, ezifanelekileyo kwiintlanga ezahlukeneyo ezibandakanya i-100m, i-400m, kunye nemigama emide.

Ekuqaleni kwenkulungwane yama-20

-IiOlimpiki zaseLondon ngo-1908:Umzila okwi-White City Stadium wawuziimitha ezingama-536.45 ubude, ubandakanya umphezulu we-cinder, obonelele ngomphezulu wokubaleka ohambelanayo noxolelayo kunokungcola. Oku kwaphawula ukuqala kokusetyenziswa kweengoma zecinder kukhuphiswano lweembaleki.

Kwinkulungwane yama-20

-1920-1950s:Ukumiselwa komgangatho wemilinganiselo yengoma yaqala, ngobude obona buxhaphakileyo baba ziimitha ezingama-400, iquka i-cinder okanye umphezulu wodongwe. Imizila yayiphawulwe ukuqinisekisa ubulungisa kukhuphiswano.

-IiOlimpiki zaseMelbourne zika-1956:Umkhondo weMelbourne Cricket Ground wenziwa ngezitena ezibomvu ezixiniweyo kunye nomhlaba, nto leyo ebonisa ulingo lwexesha lezinto ezahlukeneyo zokuphucula ukusebenza.

Era Synthetic

Ngo-1968 iiOlimpiki zesiXeko saseMexico:Oku yaba yinguqu ebalulekileyo njengoko umkhondo wenziwa ngezinto zokwenziwa (ingoma yeTartan), eyaziswa yiNkampani ye-3M. Umphezulu owenziweyo wanikezela ukutsala, ukuqina, kunye nokuxhathisa imozulu, uphucula kakhulu indlela abadlali abadlala ngayo.

Ngasekupheleni kwenkulungwane yama-20

-1976 Montreal Olympics: Ingoma ibonise umgangatho ophuculweyo owenziweyo, owaba ngumgangatho omtsha weengoma ezichwephesha kwihlabathi jikelele. Eli xesha libone ukuphucuka okubalulekileyo kuyilo lomkhondo, kugxininise kukhuseleko lweembaleki kunye nokusebenza.

Iingoma zangoku

Ngoo-1990-ngoku: Iingoma zale mihla zeOlimpiki zenziwe ngezinto ezenziwe nge-polyurethane-based synthetic. Imiphezulu yenzelwe ukusebenza kakuhle, kunye ne-cushioning yokunciphisa impembelelo kumalungu eembaleki. Ezi ndlela zilungelelaniswa zibe ziimitha ezingama-400 ubude, zinemizila esibhozo okanye esithoba, nganye iimitha ezi-1.22 ububanzi.

- 2008 Beijing Olympics: Ibala lemidlalo leSizwe, elikwabizwa ngokuba yiNyoni yeeNyoni, libonise umkhondo wokwenziwa ophucukileyo olungiselelwe ukuphucula ukusebenza kunye nokunciphisa ukonzakala. Ezi ngoma zihlala zibandakanya itekhnoloji yokulinganisa amaxesha eembaleki kunye nezinye iimetrics ngokuchanekileyo.

Inkqubela phambili yeTekhnoloji

-Iingoma ezihlakaniphile:Inkqubela phambili yamva nje ibandakanya ukudityaniswa kwetekhnoloji ehlakaniphile, enezivamvo ezizinzisiweyo zokubeka iliso kwiimethrikhi zokusebenza ezifana nesantya, amaxesha okwahlula, kunye nobude bomkhondo ngexesha lokwenyani. Olu lutsha lunceda ekuqeqesheni nasekuhlalutyeni ukusebenza.

Uphuhliso lwemo engqongileyo noluZinzileyo

- Izixhobo ezilungele i-Eco-friendly:Ugqaliselo luye lwatshintshela kuzinzo, ngokusetyenziswa kwezinto ezilungele indalo kunye nobuchule bokwakha ukunciphisa impembelelo yokusingqongileyo. Imathiriyeli enokuphinda isetyenziswe kunye neenkqubo zokwenziwa ezizinzileyo ziya zixhaphaka ngakumbi. Njengomzila wokubaleka werabha eyenziweyo.

UFakelo lweTrack yeRubber eSetyenzisiweyo

1. Isiseko kufuneka sihambe ngokwaneleyo kwaye singabi nesihlabathi. Ukuyicola nokuyilinganisela. Qinisekisa ukuba ayidluli kwi-± 3mm xa ilinganiswe nge-2m yeendlela ezithe ngqo.

4. Xa izinto eziphathekayo zifika kwindawo, indawo efanelekileyo yokubeka kufuneka ikhethwe kwangaphambili ukuququzelela umsebenzi wokuthutha olandelayo.

7. Sebenzisa isomisi seenwele ukucoca umphezulu wesiseko. Ummandla oza kuchithwa kufuneka ungabi namatye, ioli kunye nezinye izinto ezinokuthi zichaphazele i-bonding.

10. Emva kokuba imigca emi-2-3 nganye ibekwe, imilinganiselo kunye nokuhlolwa kufuneka kwenziwe ngokubhekiselele kumgca wokwakha kunye neemeko zezinto eziphathekayo, kunye nokudibanisa i-longitudinal yezinto ezidibeneyo kufuneka zihlale zihlala kumgca wokwakha.

2. Sebenzisa i-adhesive-based adhesive polyurethane ukutywina umphezulu wesiseko ukuvala izikhewu kwikhonkrithi ye-asphalt. Sebenzisa i-adhesive okanye isiseko sezinto ezisekelwe emanzini ukuze ugcwalise iindawo eziphantsi.

5. Ngokutsho kokusetyenziswa kolwakhiwo lwemihla ngemihla, izinto ezingenayo ezidibeneyo zicwangciswe kwiindawo ezihambelanayo, kwaye ii-rolls zisasazwa kumgangatho wesiseko.

8. Xa i-adhesive ikhutshiwe kwaye isetyenziswe, umkhondo we-rubber ogqityiweyo unokuvulwa ngokuhambelana nomgca wokwakhiwa kwe-paving, kwaye i-interface ihamba ngokukhawuleza kwaye ikhutshwe kwi-bond.

11. Emva kokuba umqulu wonke ulungisiwe, ukusika kwe-seam transverse kwenziwa kwisahlulo esigqithisiweyo esigcinwe xa umqulu ubekwe. Qinisekisa ukuba kukho i-adhesive eyaneleyo kumacala omabini e-transverse joints.

3. Kwisiseko sesiseko esilungisiweyo, sebenzisa i-theodolite kunye nerula yensimbi ukuze ufumane umgca wokwakhiwa kwe-paving we-rolled material, osebenza njengomgca wesalathisi sokuhamba.

6. I-adhesive enamacandelo alungiselelwe kufuneka ixutywe ngokupheleleyo. Sebenzisa i-blade ekhethekileyo yokuvuselela xa uvuselela. Ixesha lokuvuselela akufanele libe ngaphantsi kwemizuzu emi-3.

9. Kwi-surface ye-coil edibeneyo, sebenzisa i-pusher ekhethekileyo ukuze udibanise i-coil ukuphelisa ama-bubbles omoya asele ngexesha lenkqubo yokudibanisa phakathi kwekhoyili kunye nesiseko.

12. Emva kokuqinisekisa ukuba amanqaku achanekile, sebenzisa umatshini wokumakisha oyingcali ukutshiza imigca yomzila wokubaleka. Gxininisa ngokuthe ngqo kwiindawo ezichanekileyo zokutshiza. Imigca emhlophe ezotyiweyo kufuneka icace kwaye icace, nokuba ubukhulu.

Isishwankathelo

Uphuhliso lweendlela zokubaleka zeOlimpiki lubonise inkqubela phambili kwisayensi yezinto, ubunjineli, kunye nokuqonda okukhulayo kokusebenza kwembaleki kunye nokhuseleko. Ukusuka kwiindlela ezilula zokungcola kwiGreece yakudala ukuya kubuchwephesha obuphezulu bokwenziwa kumabala emidlalo anamhlanje, indaleko nganye ibe negalelo kwiimeko ezikhawulezayo, ezikhuselekileyo, nezingaguquguqukiyo ngakumbi womdyarho weembaleki kwihlabathi liphela.
