Uma kuziwa kumathrekhi e-synth, abantu abaningi bayawazi.Sekuyiminyaka engaphezu kwengama-40 kwasetshenziswa ithrekhi yokwenziwa ye-polyurethane yokuqala e-Beijing Workers' Stadium ngo-September 1979. Eminyakeni yamuva nje, imboni yezwe lami yenjoloba yokwenziwa ithuthuke ngokushesha futhi kunezinhlobo ezahlukene zemigwaqo yezindiza.
Phakathi kwawo, amathrekhi amarola enziwe ngaphambilini kancane kancane azuza isabelo semakethe, nakuba abantu abaningi benokuchayeka okulinganiselwe kuwo.Namuhla sizokhuluma ngokuthi iyini ithrekhi ye-raber roller eyenziwe ngaphambilini!
1.Ithrekhi yerola yerabha eyenziwe ngaphambilini
Ithrekhi eyenziwe ngaphambilini iwuhlobo lwethrekhi yerabha yerabha evamise ukusetshenziswa ezindaweni zemidlalo yobungcweti, okuhlanganisa amanyuvesi nezinkundla zamazwe ngamazwe.
Isekelwe kunjoloba yemvelo noma yokwenziwa futhi yenziwa kusengaphambili efektri ukuze yakhe ifilimu yogqinsi nobubanzi obuthile.Amaroli abe esethunyelwa endaweni yokufaka.Lapho isisekelo sikakhonkolo noma se-asphalt sifinyelela emazingeni adingekayo, sizofakwa ngokunembile, ngokwesayensi nangokujwayelekile ithimba lezokwakha lochwepheshe.
I-adhesive ekhethekile isetshenziswa ngesikhathi sokufakwa, futhi ukubeka amasondo ethrekhi yenjoloba kuqedwa ngezinqubo eziningi.Ithrekhi efakiwe ingafakwa ekusetshenzisweni okujwayelekile phakathi namahora angama-24.Le ndlela ihluke kakhulu ku-cast-in-place synthetic track, edinga ukulungiswa kwendawo kanye nenqubo yokufaka eyinkimbinkimbi.Ukwengeza, zidinga ukuvikelwa ngesikhathi senqubo yokwelapha futhi ngokuvamile zidinga ukunakekelwa okungaphezu kweviki ngaphambi kokusetshenziswa.
Kungani amathrekhi enjoloba enziwe ngaphambilini ehlala kancane kancane emakethe futhi abe umkhuba omusha kumathrekhi okwenziwa?Njengengoma ekhethiwe yemicimbi yezemidlalo emikhulu efana neMidlalo Yama-Olympic, ukusebenza kwayo okuhle kakhulu kusobala kubo bonke futhi yaziwa kabanzi.Ukuhumusha kunikezwa njengenhlonipho futhi akufanele kuthathwe njengokuhunyushwa okusemthethweni noma okuphrofeshinali.
2.Abahlinzeki be-membrane yerabha eyenziwe ngaphambilini
Abahlinzeki be-membrane yerabha elungiselelwe kusengaphambili - ibhekisela kubahlinzeki abangakhiqiza izinto zethrekhi zenjoloba ezenziwe kusengaphambili futhi benze ngokwezifiso izinhlobo ezihlukahlukene zolwelwesi ngokuya ngezidingo zamakhasimende.Amaroli enziwe ngaphambilini atholakala ngamasayizi ahlukahlukene, okuhlanganisa ubukhulu obuhlukahlukene, imibala, osayizi nobubanzi.Ugqinsi oluhlukene luvame ukusetshenziselwa ukubeka ezindaweni eziwugqinsi zezinkundla zemidlalo, amathrekhi epulasitiki namathrekhi epulasitiki.Abahlinzeki be-roller abakhelwe ngaphambili kuphela abangawakhiqiza ngokwezifiso uma bewacela.
Isibonelo, "i-NWT" - uhlobo lwekhwalithi ephezulu lwamasondo ethrekhi yenjoloba enziwe ngaphambili.
