Uma kukhulunywa ngokwakha indawo yokugijima ethembekile, ehlala isikhathi eside, nesebenza kahle kakhulu, amathrekhi enjoloba ahamba phambili ayikhethelo eliphezulu lezikole, izinkundla zemidlalo kanye nezindawo zokuqeqesha ezokusubatha. Nokho, impumelelo yephrojekthi yethrekhi yenjoloba incike kakhulu ekufakweni okufanele.
Kwa-NWT SPORTS, sisebenza ngokukhethekile kumasistimu ethrekhi enjoloba enziwe ngaphambilini ekhwalithi ephezulu futhi sinikeza ukwesekwa kokufakwa kochwepheshe ukuze siqinisekise ukusebenza okuhlala isikhathi eside. Kulo mhlahlandlela, sizohamba nawe enqubweni ephelele yokufaka ithrekhi yenjoloba—kusuka ekulungiseni okuyisisekelo kuya ekuqedeni kwendawo yokugcina.
1. Ukuhlolwa Kwesizinda Nokuhlela
Ngaphambi kokuthi kuqale noma yimuphi umsebenzi womzimba, ukuhlolwa kwesiza okuphelele nokuhlela kubalulekile.
· Inhlolovo yeTopographic:Hlaziya amazinga aphansi, amanzi, kanye nemithambeka yemvelo.
· Ukuhlaziya umhlabathi:Qinisekisa ukuzinza kwenhlabathi ukusekela isakhiwo sethrekhi.
· Ukucatshangelwa kwedizayini:Nquma ubukhulu bethrekhi (imvamisa engu-400m ejwayelekile), inombolo yemizila, kanye nohlobo lokusetshenziswa (ukuqeqeshwa uma kuqhathaniswa nokuncintisana).
Isakhiwo esihlelwe kahle sinciphisa izinkinga zokulungisa zesikhathi eside futhi sithuthukise ukusebenza kwezemidlalo.
2. I-Sub-Base Construction
Isizinda esincane esizinzile sibalulekile ekuhloniphekeni kwesakhiwo sethrekhi nokuphathwa kwamanzi.
· Ukumba:Geza ukujula okudingekayo (ngokuvamile 30-50 cm).
· Ukuqina:Hlanganisa i-subgrade okungenani ibe ngu-95% Modified Proctor Density.
· Indwangu ye-Geotextile:Ngokuvamile isetshenziselwa ukuvimbela ukuxutshwa kwe-subgrade kanye nezinto eziyisisekelo.
· Ungqimba Lwetshe Elichotshoziwe:Imvamisa, ugqinsi luka-15-20 cm, lunikeza ukugeleza kwamanzi nokusekela umthwalo.
I-sub-base efanele ivimbela ukuqhekeka, ukuhlalisa, nokugcwala kwamanzi ngokuhamba kwesikhathi.
3. I-Asphalt Base Layer
Isendlalelo se-asphalt esibekwe kahle sinikeza isisekelo esibushelelezi nesiqinile sendawo yenjoloba.
· Isifundo sokuhlanganisa:Ingqimba yokuqala ye-asphalt eshisayo (imvamisa i-4-6 cm ubukhulu).
· Isifundo sokugqoka:Isendlalelo se-asphalt sesibili sokuqinisekisa izinga nokufana.
· Idizayini ye-Slope:Imvamisa u-0.5–1% wethambeka elingemuva lokuphuma kwamanzi.
· Ukulinganisa kwe-Laser:Isetshenziselwa ukulinganisa okunembayo ukugwema ukungahambi kahle kwendawo.
I-asphalt kufanele yelashwe ngokuphelele (izinsuku eziyi-7-10) ngaphambi kokuqala kokufakwa kwendawo yenjoloba.
4. Ukufakwa kwe-Rubber Track Surface
Ngokuya ngohlobo lwethrekhi, kunezindlela ezimbili zokufaka eziyinhloko:
A. Ithrekhi Yerabha Eyakhiwe Ngaphambili (Kunconywe yi-NWT SPORTS)
· Okubalulekile:Amaroli ayinhlanganisela ye-EPDM+ekhiqizwe efekthri anogqinsi kanye nokusebenza okungaguquki.
· Ukunamathela:Indawo engaphezulu ihlanganiswe ne-asphalt ene-polyurethane enamathelayo ephezulu.
· Ukuthunga:Amalunga phakathi kwemiqulu aqondaniswe ngokucophelela futhi avalwe.
· Ukumaka komugqa:Ngemuva kokuthi ithrekhi iboshwe ngokugcwele futhi yelaphekile, imigqa ipendwe kusetshenziswa upende oqinile owenziwe nge-polyurethane.
· Izinzuzo:Ukufakwa okusheshayo, ukulawula ikhwalithi engcono, ukusebenza kwendawo engaguquki.
B. In-Situ Ethelwe Ngenjoloba Ithrekhi
· Isendlalelo sesisekelo:Izinhlamvu zenjoloba ze-SBR ezixutshwe ne-binder futhi zithululelwe esizeni.
· Isendlalelo esiphezulu:Izinhlamvu ze-EPDM zisetshenziswa ngejazi lesifutho noma uhlelo lwesemishi.
· Isikhathi sokuphumula:Iyahlukahluka kuye ngezinga lokushisa kanye nomswakama.
Qaphela: Amasistimu e-in-situ adinga ukulawula isimo sezulu okuqinile kanye nochwepheshe abanolwazi.
5. Ukumakwa Komugqa kanye Nokuhlolwa Kokugcina
Ngemuva kokuthi i-rubber surface ifakwe ngokugcwele futhi ilapheka:
· Ukumaka komugqa:Ukulinganisa okunembayo nokudweba kwemigqa yelayini, izindawo zokuqala/zokuqeda, izimpawu zokuthiyo, njll.
· Ukuhlolwa kwe-Friction & Shock Absorption:Ukuqinisekisa ukuthotshelwa kwamazinga omhlaba (isb, IAAF/World Athletics).
· Ukuhlolwa kwe-Drainage:Qinisekisa ukuthambeka okufanele kanye nokungabikho kokuhlanganisa amanzi.
· Ukuhlola Okokugcina:Ukuqinisekisa ikhwalithi ngaphambi kokunikezela.
6. Amathiphu Okulungisa Ukusebenza Kwesikhathi Eside
·Ukuhlanza njalo ukususa uthuli, amaqabunga, nemfucumfucu.
·Gwema ukufinyelela imoto noma ukuhudula izinto ezicijile.
·Lungisa ngokushesha noma yimuphi umonakalo ongaphezulu noma ukuguga komphetho.
·Ukupendwa kabusha kolayini bemizila njalo eminyakeni embalwa ukuze kugcinwe ukubonakala.
Ngokunakekelwa okufanele, amathrekhi enjoloba e-NWT SPORTS angahlala iminyaka engu-10–15+ ngokulungiswa okuncane.
