Xov Xwm - Lub Evolution ntawm Olympic Running Track Surface Construction

Keeb kwm ntawmOlympic khiav lemqhia txog kev nthuav dav hauv kev ua kis las technology, kev tsim kho, thiab cov khoom siv. Nov yog cov ncauj lus kom ntxaws txog lawv cov evolution:

Ancient Olympics

- Cov Kev Ua Si Thaum Ntxov (circa 776 BC):Thawj qhov kev ua si Olympic tau tuav hauv Olympia, Tim Nkij teb chaws, muaj ib qho kev tshwm sim hu ua kev sib tw stadion, kwv yees li 192 meters ntev. Txoj kev taug yog txoj kev yooj yim, ncaj av.

Niaj hnub nimno Olympics

- 1896 Athens Olympics:Thawj qhov kev ua si Olympic niaj hnub no muaj kev sib tw khiav hauv Panathenaic Stadium, txoj kev ncaj 333.33-meter ua los ntawm cov pob zeb thiab cov xuab zeb, haum rau ntau yam kev sib tw nrog rau 100m, 400m, thiab ntev dua.

Thaum ntxov 20th caug xyoo

- 1908 London Olympics:Txoj kev taug kev ntawm White City Stadium yog 536.45 meters ntev, suav nrog lub ntsej muag cinder, uas muab qhov sib xws thiab zam kev ua haujlwm ntau dua li av. Qhov no tau cim qhov pib ntawm kev siv cinder lem hauv kev ua kis las.

Mid 20th caug xyoo

Xyoo 1920-1950s:Kev tsim qauv ntawm qhov ntev tau pib, nrog qhov ntev tshaj plaws ua 400 meters, muaj cov cinder lossis av nplaum. Cov kab khiav tau raug cim kom muaj kev ncaj ncees hauv kev sib tw.

- 1956 Melbourne Olympics:Melbourne Cricket Ground txoj kev taug qab yog ua los ntawm cov pob zeb liab thiab lub ntiaj teb, qhia txog lub sijhawm kev sim nrog ntau yam ntaub ntawv los txhim kho kev ua haujlwm.

Synthetic Era

- 1968 Mexico City Olympics:Qhov no yog qhov hloov pauv tseem ceeb raws li txoj kev taug qab yog tsim los ntawm cov khoom siv hluavtaws (Tartan khiav), qhia los ntawm 3M Tuam Txhab. Cov nplaim hluavtaws muab kev zoo dua traction, durability, thiab huab cua tsis kam, ua kom cov neeg ncaws pob ua tau zoo.

Xyoo 20th lig

-Xyoo 1976 Montreal Olympics: Txoj kev taug qab tau nthuav tawm qhov kev txhim kho hluavtaws, uas tau dhau los ua tus qauv tshiab rau kev ua haujlwm thoob ntiaj teb. Lub sijhawm no tau pom kev txhim kho tseem ceeb hauv kev tsim qauv, tsom mus rau kev nyab xeeb ntawm kev ncaws pob thiab kev ua haujlwm.

Niaj hnub nimno Tracks

-1990s-Tam sim no: Niaj hnub nimno Olympic lem yog ua los ntawm advanced polyurethane-raws li cov khoom siv hluavtaws. Cov npoo yog tsim los rau kev ua haujlwm zoo, nrog cushioning kom txo tau qhov cuam tshuam ntawm cov pob qij txha. Cov lem no yog standardized ntawm 400 meters nyob rau hauv ntev, nrog yim los yog cuaj kab, txhua 1.22 meters dav.

- 2008 Beijing Olympics: Lub Chaw Ua Si Hauv Tebchaws, tseem hu ua Bird's Zes, nthuav tawm cov khoom siv hluav taws xob uas tsim los txhim kho kev ua tau zoo thiab txo qis kev raug mob. Cov kab no feem ntau suav nrog kev siv thev naus laus zis los ntsuas cov neeg ncaws pob lub sijhawm thiab lwm yam kev ntsuas kom raug.

Technological Advances

-Smart Tracks:Cov kev nce qib tshiab tshaj plaws suav nrog kev sib koom ua ke ntawm cov cuab yeej ntse, nrog cov ntsuas ntsuas los saib xyuas cov ntsuas kev ua tau zoo xws li kev nrawm, sib cais lub sijhawm, thiab kev sib tw ntev hauv lub sijhawm. Cov kev tsim kho tshiab no pab hauv kev cob qhia thiab kev txheeb xyuas kev ua haujlwm.

Environmental thiab Sustainable Developments

- Eco-phooj ywg cov ntaub ntawv:Lub hom phiaj tseem ceeb tau hloov mus rau kev ruaj khov, nrog rau kev siv cov khoom siv hauv eco-friendly thiab kev tsim kho kom txo tau qhov cuam tshuam ib puag ncig. Cov khoom siv rov ua dua tshiab thiab cov txheej txheem tsim khoom lag luam tau dhau los ua ntau dua. Xws li prefabricated roj hmab khiav khiav.

Prefabricated Rubber Running Track Installation

1. Lub hauv paus yuav tsum du txaus thiab tsis muaj xuab zeb. Sib tsoo thiab leveling nws. Nco ntsoov nws tsis tshaj ± 3 hli thaum ntsuas los ntawm 2m straightedges.

4. Thaum cov ntaub ntawv tuaj txog ntawm qhov chaw, qhov chaw tso cai tsim nyog yuav tsum tau xaiv ua ntej kom yooj yim rau kev thauj mus los tom ntej.

7. Siv lub tshuab ziab plaub hau los ntxuav qhov chaw ntawm lub hauv paus. Lub cheeb tsam yuav tsum tau khawb yuav tsum tsis muaj pob zeb, roj thiab lwm yam khib nyiab uas yuav cuam tshuam rau kev sib txuas.

10. Tom qab txhua 2-3 kab tau muab tso rau, kev ntsuas thiab tshuaj xyuas yuav tsum tau ua nrog kev siv cov kab kev tsim kho thiab cov khoom siv, thiab cov kab sib txuas ntev ntawm cov ntaub ntawv coiled yuav tsum nyob ntawm txoj kab kev tsim kho.

2. Siv polyurethane-raws li adhesive los khi rau saum npoo ntawm lub hauv paus kom kaw qhov khoob hauv cov pob zeb asphalt. Siv cov nplaum nplaum los yog cov khoom siv hauv dej los sau cov chaw qis.

5. Raws li kev siv niaj hnub siv, cov khoom siv coiled tuaj yeem raug teeb tsa hauv qhov chaw sib thooj, thiab cov yob tau nthuav dav rau ntawm lub hauv paus nto.

8. Thaum cov nplaum nplaum yog khawb thiab siv, cov roj hmab rub tawm tuaj yeem nthuav tawm raws li cov paving siv kab, thiab lub interface yog maj mam dov thiab extruded rau daim ntawv cog lus.

11. Tom qab tag nrho cov yob yog tsau, transverse seam txiav yog ua nyob rau hauv overlapped feem reserved thaum lub yob yog nteg. Nco ntsoov tias muaj cov nplaum txaus ntawm ob sab ntawm cov pob qij txha transverse.

3. Ntawm qhov chaw kho lub hauv paus, siv theodolite thiab steel kav los nrhiav cov paving siv kab ntawm cov khoom siv dov, uas ua haujlwm raws li qhov taw qhia kab rau kev khiav.

6. Cov nplaum nplaum nrog cov khoom npaj yuav tsum tau nplawm tag nrho. Siv ib rab riam tshwj xeeb nplawm thaum nplawm. Lub sijhawm stirring yuav tsum tsis pub tsawg tshaj 3 feeb.

9. Nyob rau saum npoo ntawm cov coil sib txuas, siv lub zog tshwj xeeb los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tshem tawm cov npuas npuas uas tseem tshuav thaum lub sij hawm sib txuas ntawm lub kauj thiab lub hauv paus.

12. Tom qab paub meej tias cov ntsiab lus yog lawm, siv lub tshuab cim kev tshaj lij los txau cov kab khiav khiav. Ua tib zoo saib xyuas cov ntsiab lus tseeb rau kev txau. Cov kab dawb kos yuav tsum meej thiab nkig, txawm nyob hauv tuab.

Cov ntsiab lus

Txoj kev loj hlob ntawm kev sib tw Olympic tau tsom mus rau kev nce qib hauv cov ntaub ntawv tshawb fawb, engineering, thiab kev nkag siab txog kev ua kis las thiab kev nyab xeeb. Los ntawm txoj kev yooj yim av hauv tebchaws Greece thaum ub mus rau cov khoom siv hluav taws xob siab hauv cov chaw ua si niaj hnub no, txhua qhov kev hloov pauv tau ua rau muaj kev sib tw nrawm dua, muaj kev nyab xeeb, thiab sib tw ntau dua rau cov neeg ncaws pob thoob ntiaj teb.
