Izindaba - Ukuvela Kokwakhiwa Kwethrekhi Yethrekhi Yama-Olympic

Umlando weAmathrekhi wokugijima wama-Olympicibonisa izitayela ezibanzi kubuchwepheshe bezemidlalo, ukwakhiwa, nezinto zokwakha. Nakhu ukubuka okuningiliziwe kokuvela kwabo:

Amathrekhi wokugijima wama-Olympic cinder topolyurethane

Ama-Olympics asendulo

- Amaculo Okuqala (cishe 776 BC):Imidlalo yama-Olympic yokuqala eyayibanjelwe e-Olympia, eGreece, yayinomcimbi owodwa obizwa ngokuthi umjaho wezinkundla, cishe ubude obungamamitha angu-192. Ithrekhi bekuyindlela yokungcola elula, eqondile.

Ama-Olympics anamuhla

- 1896 Athens Olympics:Imidlalo yama-Olympic yokuqala yesimanje yayinomzila wokugijima e-Panathenaic Stadium, ithrekhi eqondile engamamitha angu-333.33 eyenziwe ngamatshe agayiwe nesihlabathi, elungele imijaho eyahlukene okuhlanganisa i-100m, 400m, namabanga amade.

Ekuqaleni kwekhulu lama-20

- 1908 London Olympics:Ithrekhi e-White City Stadium yayingamamitha angu-536.45 ubude, ihlanganisa indawo ye-cinder, enikeza indawo egijima engaguquki futhi ethethelelayo kunokungcola. Lokhu kuphawule ukuqala kokusetshenziswa kwamathrekhi e-cinder ku-athletics.

Maphakathi nekhulu lama-20

- 1920s-1950s:Ukumiswa kobukhulu bethrekhi kwaqala, ngobude obuvame kakhulu baba amamitha angu-400, okufaka i-cinder noma indawo yobumba. Imizila yayimakwa ukuze kuqinisekiswe ubuqotho emqhudelwaneni.

- 1956 Melbourne Olympics:Ithrekhi ye-Melbourne Cricket Ground yenziwe ngesitini esibomvu esicindezelweyo kanye nomhlaba, okubonisa ukuhlolwa kwenkathi ngezinto ezihlukahlukene zokuthuthukisa ukusebenza.

I-Synthetic Era

- 1968 Mexico City Olympics:Lokhu kube yinguquko ebalulekile njengoba ithrekhi yenziwe ngezinto zokwenziwa (ithrekhi ye-Tartan), eyethulwe yi-3M Company. Indawo yokwenziwa inikeze ukudonseka okungcono, ukuqina, nokumelana nesimo sezulu, okuthuthukisa kakhulu ukusebenza kwabasubathi.

Ekupheleni kwekhulu lama-20

-1976 Montreal Olympics: Ithrekhi ifake indawo yokwenziwa ethuthukisiwe, okube izinga elisha lamathrekhi angochwepheshe emhlabeni jikelele. Lesi sikhathi sibone ukuthuthuka okubalulekile ekwakhiweni kwethrekhi, okugxile ekuphepheni nasekusebenzeni kwabasubathi.

Amaculo Esimanje

- 1990s-Okwamanje: Amathrekhi esimanje wama-Olympic enziwe ngezinto zokwenziwa ezisekelwe ku-polyurethane ezithuthukisiwe. Indawo engaphezulu yakhelwe ukusebenza kahle, nge-cushioning yokunciphisa umthelela kumalunga abagijimi. Lawa mathrekhi alinganiswe abe ngamamitha angu-400 ubude, anemizila eyisishiyagalombili noma eyisishiyagalolunye, ngamunye ngamamitha angu-1.22 ububanzi.

- 2008 Beijing Olympics: Inkundla Yezemidlalo Kazwelonke, eyaziwa nangokuthi i-Bird's Nest, inengoma yokwenziwa esezingeni eliphezulu edizayinelwe ukuthuthukisa ukusebenza nokunciphisa ukulimala. Lawa mathrekhi ngokuvamile ahlanganisa ubuchwepheshe bokulinganisa izikhathi zabasubathi namanye ama-metric ngokunembile.

Intuthuko Yezobuchwepheshe

-Amathrekhi ahlakaniphile:Intuthuko yakamuva ihlanganisa ukuhlanganiswa kobuchwepheshe obuhlakaniphile, nezinzwa ezishumekiwe zokuqapha amamethrikhi okusebenza njengesivinini, izikhathi zokuhlukaniswa, nobude bokugxambukela ngesikhathi sangempela. Lezi zindlela ezintsha zisiza ekuqeqesheni nasekuhlaziyeni ukusebenza.

Intuthuko Yezemvelo kanye Nesimeme

- Izinto ezisetshenziswayo eco-friendly:Ukugxila kuphinde kwashintshela ekuzinzeni, ngokusetshenziswa kwezinto ezivumelana nemvelo nezindlela zokwakha ukuze kuncishiswe umthelela wendawo. Izinto ezisetshenziswayo ezigaywa kabusha kanye nezinqubo zokukhiqiza ezizinzile ziya ngokuya zivame kakhulu. Njengethrekhi yokugijima yerabha eyenziwe ngaphambilini.

Ukufakwa Kwethrekhi Yenjoloba Eyakhiwe ngaphambilini

1. Isisekelo kufanele sibe bushelelezi ngokwanele futhi singabi nesihlabathi. Ukuyigaya nokuyibeka ezingeni. Qiniseka ukuthi aweqeli ± 3mm uma ukalwa ngo-2m oqondile.

4. Lapho izinto ezisetshenziswayo zifika esizeni, indawo efanele yokubeka kufanele ikhethwe kusengaphambili ukuze kube lula umsebenzi wokuthutha olandelayo.

7. Sebenzisa isomisi sezinwele ukuhlanza ubuso besisekelo. Indawo ezokwalwa kumele ingabi namatshe, amafutha kanye nezinye izibi ezingase zibe nomthelela ekubopheni.

10. Ngemuva kokuthi imigqa engu-2-3 ngayinye ibekwe, izilinganiso nokuhlolwa kufanele kwenziwe ngokubhekiselwe kumugqa wokwakha kanye nezimo zempahla, futhi amalunga obude bezinto ezihlanganisiwe kufanele ahlale emgqeni wokwakha.

2. Sebenzisa i-polyurethane-based adhesive ukuze uvale ubuso besisekelo ukuze uvale izikhala kukhonkolo ye-asphalt. Sebenzisa izinto ezinamathelayo noma ezisekelwe emanzini ukuze ugcwalise izindawo eziphansi.

5. Ngokusho kokusetshenziswa kokwakhiwa kwansuku zonke, izinto ezihlanganisiwe ezingenayo zihlelwa ezindaweni ezihambisanayo, futhi imiqulu isakazwa endaweni yesisekelo.

8. Uma i-adhesive icwecwa futhi isetshenziswa, ithrekhi yenjoloba egoqiwe ingavulwa ngokusho komugqa wokwakhiwa kwe-paving, futhi isikhombimsebenzisi sigoqeka kancane futhi sikhishwe ku-bond.

11. Ngemuva kokuthi wonke umqulu usulungisiwe, ukusika kwe-seam okuphambene kwenziwa engxenyeni egqagqene egcinwe lapho kubekwa umqulu. Qinisekisa ukuthi kukhona okunamathelayo okwanele ezinhlangothini zombili zamalunga aguquguqukayo.

3. Endaweni yesisekelo esilungisiwe, sebenzisa i-theodolite nerula yensimbi ukuze uthole umugqa wokwakha ogandayiwe wezinto ezigoqiwe, osebenza njengomugqa wenkomba wokugijima kwethrekhi.

6. I-adhesive enezingxenye ezilungiselelwe kufanele ishukunyiswe ngokugcwele. Sebenzisa i-blade eshukumisayo ekhethekile lapho ushukumisa. Isikhathi sokugqugquzela akufanele sibe ngaphansi kwemizuzu emi-3.

9. Ebusweni bekhoyili eboshiwe, sebenzisa ipusher ekhethekile ukuze unciphise ikhoyili ukuze uqede amabhamuza omoya asele phakathi nenqubo yokuhlanganisa phakathi kwekhoyili nesisekelo.

12. Ngemva kokuqinisekisa ukuthi amaphuzu anembile, sebenzisa umshini womaka wochwepheshe ukuze ufafaze imigqa yomzila wethrekhi ogijimayo. Bheka ngokuqondile amaphuzu okufafaza ngawo. Imigqa emhlophe edwetshiwe kufanele icace futhi icwebe, ngisho nogqinsi.

Isifinyezo

Ukuthuthukiswa kwamathrekhi okugijima ama-Olympic kubonise intuthuko kwezesayensi yezinto zokwakha, ubunjiniyela, nokuqonda okukhulayo kokusebenza nokuphepha kwezokusubatha. Kusukela ezindleleni zokungcola ezilula eGreece yasendulo ukuya ezindaweni zokwenziwa zobuchwepheshe obuphezulu ezinkundleni zesimanjemanje, ukuziphendukela kwemvelo ngakunye kube nomthelela ezimweni zomjaho ezisheshayo, eziphephile, nezingaguquguquki kakhudlwana kubasubathi emhlabeni jikelele.
