Nhau - The Evolution of Olympic Running Track Surface Construction

Nhoroondo yeMitambo yeOlympic yekumhanyainoratidza maitiro akakura muhunyanzvi hwemitambo, kuvaka, uye zvinhu. Heino kutarisisa kwakadzama kwekushanduka kwavo:

Mitambo yeOlympic inomhanya cinder topolyurethane

MaOlympics ekare

- Makwara ekutanga (kusvika 776 BC):Mitambo yeOlympic yepakutanga yakaitirwa muOlympia, Greece, yaisanganisira chiitiko chimwe chete chinonzi mujaho westadion, kureba kwemamita 192. Nzira yacho yakanga iri nyore, nzira yetsvina yakatwasuka.

MaOlympics emazuva ano

- 1896 Athens Olympics:Mitambo yeOlympic yekutanga yemazuva ano yairatidza nzira yekumhanya muPanathenaic Stadium, yakatwasuka 333.33-metres track yakagadzirwa nematombo akapwanyika nejecha, inokodzera mijaho yakasiyana siyana inosanganisira 100m, 400m, uye kureba.

Kutanga kwezana remakore rechi20

- 1908 London Olympics:Nzira yeWhite City Stadium yakanga yakareba mamita 536.45, ichibatanidza cinder pamusoro, iyo yakapa nzvimbo inowirirana uye inokanganwira inomhanya kupfuura tsvina. Izvi zvakaratidza kutanga kwekushandiswa kwenzimbe dzema<em>cinder mumitambo.

Mid 20th Century

- 1920s-1950s:Kumisikidzwa kwematanho etrack kwakatanga, nehurefu hwakajairika huchive 400 metres, iine cinder kana ivhu. Mikoto yacho yaiiswa zviratidzo kuitira kuti pave nokururamisira mumakwikwi.

- 1956 Melbourne Olympics:Iyo Melbourne Cricket Ground's track yakagadzirwa nezvidhinha zvitsvuku uye pasi, zvichiratidza kuyedza kwenguva nezvinhu zvakasiyana siyana zvekuvandudza mashandiro.

Synthetic Era

- 1968 Mexico City Olympics:Iyi yaive shanduko yakakosha sezvo track yaive yakagadzirwa neyakagadzirwa zvinhu (Tartan track), yakaunzwa ne3M Company. Nzvimbo yekugadzira yakapa kukweva kuri nani, kusimba, uye kusamira kwemamiriro ekunze, zvichivandudza matambiro evatambi zvakanyanya.

Pakupera kwezana remakore rechi20

-1976 Montreal Olympics: Iyo track yakaratidza yakagadziridzwa yekugadzira nzvimbo, iyo yakave chiyero chitsva chenyanzvi dzemateki pasi rese. Nguva ino yakaona kuvandudzwa kwakakosha mukugadzira njanji, tichitarisa kuchengetedzeka kwevatambi uye kuita.

Mazuvano Tracks

1990s-Iyezvino: Mitambo yeOlympic yemazuva ano inogadzirwa neyemhando yepamusoro polyurethane-based synthetic materials. Nzvimbo dzakagadzirirwa kuita zvakaringana, ne cushioning kuderedza kukanganiswa pamajoini evamhanyi. Manjanji aya akajairwa kuita 400 metres pakureba, aine mikoto misere kana mipfumbamwe, imwe neimwe yakafara mamita 1.22.

- 2008 Beijing Olympics: Nhandare yeNyika, inonziwo Bird's Nest, ine nzira yekugadzira yekucheka-cheka yakagadzirirwa kuwedzera kushanda uye kuderedza kukuvara. Matinji aya anowanzo batanidza tekinoroji yekuyera nguva dzevatambi uye mamwe metric nemazvo.

Technology Advans

-Smart Tracks:Iko kufambira mberi kwazvino kunosanganisira kubatanidzwa kwehunyanzvi tekinoroji, ine ma sensors akadzamirirwa ekutarisa ma metrics ekuita senge kumhanya, nguva dzakapatsanurwa, uye nhanho kureba munguva chaiyo-nguva. Aya matsva anobatsira mukudzidziswa nekuongorora kwekuita.

Mafambiro Ezvakatipoteredza uye Anoenderera mberi

- Eco-hushamwari zvinhu:Iyo tarisiro yakachinjika zvakare kune inoenderera, nekushandiswa kweeco-inoshamwaridzika zvinhu uye maitiro ekuvaka kudzikisa kukanganisa kwezvakatipoteredza. Zvishandiso zvinogadziriswa uye maitiro ekugadzira anoenderera ari kuwedzera kuwanda. Zvakadai seye prefabricated rubber running track.

Prefabricated Rubber Running Track Kuisa

1. Nheyo inofanira kuva yakatsetseka zvakakwana uye isina jecha. Kukuya nekuienzanisa. Iva nechokwadi kuti haipfuure ± 3mm kana yakayerwa ne2m yakatwasuka.

4. Kana zvinhu zvinosvika panzvimbo, nzvimbo yakakodzera yekuisa inofanira kusarudzwa pachine nguva kuti iite basa rekufambisa rinotevera.

7. Shandisa bvudzi rebvudzi kuti uchenese pamusoro penheyo. Nzvimbo inofanira kukweshwa inofanira kunge isina matombo, mafuta uye mamwe marara anogona kukanganisa kubatana.

10. Mushure mokunge mitsara yega yega 2-3 yaiswa, zviyero uye kuongororwa kunofanira kuitwa maererano nemutsara wekuvaka uye zvinhu zvezvinhu, uye majoini ehurefu ezvigadzirwa zvakasungirirwa zvinofanira kugara zviri pamutsara wekuvaka.

2. Shandisa polyurethane-based adhesive kuti uvhare pamusoro penheyo kuti uvhare mapeji muasphalt concrete. Shandisa adhesive kana mvura-based base zvinhu kuzadza nzvimbo dzakaderera.

5. Maererano nekushandiswa kwezuva nezuva kwekuvaka, zvinhu zvinopinda zvakaputirwa zvakarongwa munzvimbo dzinoenderana, uye mipumburu inopararira pamusoro penheyo.

8. Kana iyo yakanamatira ichiputirwa uye yakashandiswa, iyo yakapetwa rubber track inogona kuvhurwa maererano neyakagadzika mutsara wekuvaka, uye iyo interface inopetwa zvishoma nezvishoma uye yakawedzerwa kune chisungo.

. Ita shuwa kuti pane anonamira akakwana pamativi ese emajoini akachinjika.

3. Pamusoro pekugadzirisa nheyo yepamusoro, shandisa theodolite uye mutongi wesimbi kuti uwane mutsara wekugadzira wekugadzira wezvinhu zvakapeteredzwa, izvo zvinoshanda sechiratidzo chekumhanya.

6. Iyo yakanamatira ine zvikamu zvakagadzirirwa inofanira kunge yakazara. Shandisai blade yakakosha yekukuchidzira paunenge uchikurunga. Nguva yekukurudzira haifaniri kunge iri pasi pemaminitsi matatu.

9. Pamusoro peiyo yakasungwa coil, shandisa yakakosha pusher kuti iparadze coil kuti ibvise mabhubhu emhepo akasara panguva yekubatanidza pakati pekoiri uye nheyo.

12. Mushure mekusimbisa kuti mapoinzi akarurama, shandisai nyanzvi yekumaka muchina kupfapfaidza mitsetse yekumhanya. Nyatsotaura kune chaiwo mapoinzi ekupfapfaidza. Mitsetse michena yakadhirowewa inofanirwa kuve yakajeka uye yakatsetseka, kunyangwe mukukora.

Summary

Kuvandudzwa kwemitambo yekumhanya yeOlympic kwakaratidza kufambira mberi mune zvesainzi, engineering, uye kunzwisisa kuri kukura kwekuita kwemumhanyi uye kuchengeteka. Kubva kunzira dzakareruka dzetsvina muGreece yekare kuenda kunzvimbo dzepamusoro-tekinoroji dzekugadzira munhandare dzemazuva ano, shanduko yega yega yakabatsira kukurumidza, kwakachengeteka, uye kunoenderana mamiriro emujaho evatambi pasi rese.
