Nkhani - Kusintha kwa Olympic Running Track Surface Construction

Mbiri yaMasewera othamanga a Olimpikizikuwonetsa zomwe zikuchitika muukadaulo wamasewera, zomangamanga, ndi zida. Nayi kuyang'ana mwatsatanetsatane za kusinthika kwawo:

Masewera othamanga a Olimpiki a cinder topolyurethane

Masewera a Olimpiki Akale

- Nyimbo Zoyambirira (cha m'ma 776 BC):Masewera a Olimpiki oyambirira omwe anachitikira ku Olympia, Greece, anali ndi chochitika chimodzi chotchedwa stadion race, pafupifupi mamita 192 kutalika. Njirayi inali njira yosavuta, yowongoka yadothi.

Masewera a Olimpiki Amakono

1896 Athens Olimpiki:Masewera a Olimpiki amakono oyambirira anali ndi njira yothamanga mu Panathenaic Stadium, njira yowongoka ya mamita 333.33 yopangidwa ndi miyala yophwanyidwa ndi mchenga, yoyenera kwa mitundu yosiyanasiyana kuphatikizapo 100m, 400m, ndi mtunda wautali.

Chiyambi cha 20th Century

1908 London Olympics:Njira ya ku White City Stadium inali yautali wa mamita 536.45, kuphatikizirapo cinder pamwamba, zomwe zinapereka malo othamanga komanso okhululuka kuposa dothi. Ichi chinali chiyambi cha kugwiritsa ntchito njanji za cinder pamasewera othamanga.

Pakati pa 20th Century

- 1920s-1950s:Kuyimitsidwa kwa miyeso ya njanji kunayamba, ndipo kutalika kofala kwambiri kukhala mamita 400, okhala ndi cinder kapena dongo. Misewuyi idayikidwa chizindikiro kuti pakhale chilungamo pamipikisano.

1956 Melbourne Olimpiki:Njira ya Melbourne Cricket Ground idapangidwa ndi njerwa zofiyira komanso nthaka, zomwe zikuwonetsa kuyesa kwanthawiyo ndi zida zosiyanasiyana kuti zithandizire magwiridwe antchito.

Synthetic Era

1968 Mexico City Olimpiki:Izi zidasintha kwambiri chifukwa njanjiyo idapangidwa ndi zinthu zopangira (Tartan track), yomwe idayambitsidwa ndi 3M Company. Malo opangidwawo ankathandiza kuti anthu azigwira bwino ntchito, azikhala olimba, komanso kuti asavutike ndi nyengo, zomwe zinkathandiza kuti othamanga azisewera bwino kwambiri.

Chakumapeto kwa 20th Century

-1976 Olympics ku Montreal: Nyimboyi inali ndi malo opangidwa bwino, omwe adakhala muyeso watsopano wama track a akatswiri padziko lonse lapansi. Nthawi imeneyi idawona kusintha kwakukulu pamapangidwe a njanji, kuyang'ana kwambiri chitetezo cha othamanga ndi magwiridwe antchito.

Nyimbo Zamakono

- 1990s-Present: Nyimbo zamakono za Olimpiki zimapangidwa ndi zipangizo zamakono zopangidwa ndi polyurethane. Maonekedwewa amapangidwa kuti azigwira bwino ntchito, ndi ma cushioning kuti achepetse kukhudzidwa kwa othamanga. Manjanjiwa amafanana ndi mamita 400 m'litali, ndi misewu isanu ndi itatu kapena isanu ndi inayi, iliyonse ndi mamita 1.22 m'lifupi.

- Masewera a Olimpiki a Beijing a 2008: Bwalo la National Stadium, lomwe limadziwikanso kuti Bird's Nest, linali ndi nyimbo yotsogola yopangidwa kuti ipititse patsogolo magwiridwe antchito komanso kuchepetsa kuvulala. Matinjiwa nthawi zambiri amaphatikiza ukadaulo woyezera nthawi za othamanga ndi ma metrics ena molondola.

Zotsogola Zatekinoloje

-Nyimbo Zanzeru:Kupita patsogolo kwaposachedwa kumaphatikizapo kuphatikiza kwaukadaulo wanzeru, wokhala ndi masensa ophatikizidwa kuti azitha kuyang'anira magwiridwe antchito monga kuthamanga, nthawi zogawanika, ndi kutalika kwa nthawi yeniyeni. Zatsopanozi zimathandizira pakuphunzitsa ndi kusanthula magwiridwe antchito.

Zotukuka Zachilengedwe ndi Zokhazikika

- Zipangizo zokomera zachilengedwe:Cholinga chake chasinthiranso kukhazikika, pogwiritsa ntchito zida zokomera zachilengedwe komanso njira zomangira kuti muchepetse kuwonongeka kwa chilengedwe. Zida zobwezeretsedwanso komanso njira zopangira zokhazikika zikuchulukirachulukira. Monga njanji yopangira mphira.

Kukhazikitsa kokhazikika kwa Rubber Running Track

1. Maziko ayenera kukhala osalala mokwanira komanso opanda mchenga. Kupera ndi kusalaza. Onetsetsani kuti sichidutsa ± 3mm poyezedwa ndi 2m zowongoka.

4. Zida zikafika pamalowo, malo oyenerera ayenera kusankhidwa pasadakhale kuti athandizire ntchito yoyendera.

7. Gwiritsani ntchito chowumitsira tsitsi kuti muyeretse pamwamba pa maziko. Malo oti aphwanye ayenera kukhala opanda miyala, mafuta ndi zinyalala zina zomwe zingakhudze kugwirizana.

10. Pambuyo pa mizere ya 2-3 iliyonse yaikidwa, miyeso ndi kufufuza ziyenera kuchitidwa ponena za mzere womanga ndi zinthu zakuthupi, ndipo maulendo aatali a zipangizo zophimbidwa ayenera kukhala nthawi zonse pamzere womanga.

2. Gwiritsani ntchito zomatira za polyurethane kuti musindikize pamwamba pa maziko kuti mutseke mipata mu konkire ya asphalt. Gwiritsani ntchito zomatira kapena zotengera madzi kuti mudzaze malo otsika.

5. Malingana ndi ntchito yomanga tsiku ndi tsiku, zipangizo zolowera zozungulira zimakonzedwa m'madera ogwirizana, ndipo mipukutu imafalikira pa maziko a maziko.

8. Pamene zomatirazo zikuphwanyidwa ndikugwiritsidwa ntchito, njanji ya rabara yogubuduza imatha kuwululidwa molingana ndi mzere womangamanga, ndipo mawonekedwewo amakulungidwa pang'onopang'ono ndikutulutsidwa kuti agwirizane.

11. Pambuyo pake mpukutu wonsewo utakhazikika, kudula kwa msoko kumachitika pagawo lophatikizika losungidwa pamene mpukutuwo wayikidwa. Onetsetsani kuti pali zomatira zokwanira mbali zonse ziwiri za mfundo zopingasa.

3. Pa maziko okonzedwa, gwiritsani ntchito theodolite ndi wolamulira wachitsulo kuti mupeze mzere womangapo wa zinthu zogubuduzika, zomwe zimakhala ngati mzere wowonetsera kuthamanga.

6. Zomatira ndi zigawo zokonzekera ziyenera kugwedezeka mokwanira. Gwiritsani ntchito tsamba lapadera logwedeza poyambitsa. Kuyambitsa nthawi sikuyenera kuchepera mphindi zitatu.

9. Pamwamba pa coil yomangika, gwiritsani ntchito chopukusira chapadera kuti muphwanye koyilo kuti muchotse thovu la mpweya lomwe limakhalapo panthawi yogwirizanitsa pakati pa koyilo ndi maziko.

12. Mukatsimikizira kuti mfundozo ndi zolondola, gwiritsani ntchito makina osindikizira kuti mupope mizere yothamanga. Kunena zoona zenizeni za kupopera mbewu mankhwalawa. Mizere yoyera yojambulidwa iyenera kukhala yomveka bwino komanso yowoneka bwino, ngakhale yokhuthala.

Chidule

Kukula kwa mayendedwe othamanga a Olimpiki kwawonetsa kupita patsogolo kwa sayansi yazinthu, uinjiniya, komanso kumvetsetsa bwino kwamasewera ndi chitetezo. Kuchokera kunjira zosavuta zauve ku Girisi wakale kupita kumalo opangira umisiri wapamwamba kwambiri m'mabwalo amakono, kusinthika kulikonse kwathandizira kuti mipikisano yachangu, yotetezeka, komanso yosasinthika kwa othamanga padziko lonse lapansi.
