Umdwebo Wokuklama
400M Isidingo:
Isisekelo Processing
Izidingo zesisekelo se-asphalt
Izinsiza zokudonsa amanzi
Ukufakwa kwezingxenye ezishumekiwe:
Itiyela letiyela lezidingo eziyisisekelo:
1. Sebenzisa izinto eziyisisekelo ezisekelwe emanzini ukuze uvale indawo ephansi futhi uvale izikhala kukhonkolo ye-asphalt.
2. Yenza ukuhlolwa kokunisela ukuze uthole ukudangala.
3. Sebenzisa izinto eziyisisekelo ezisekelwe emanzini ukuze ugcwalise ama-depression aphansi, futhi usebenzise isikhathi eside kunomkhiqizo.
Ibha eqondile enobubanzi bamanzi obuyi-2m kufanele ichithwe ngokuphindaphindiwe ngaphandle kwezigaxa. amagagasi agelezayo.
4. Zama ukwenza umthambeka ngokwendlela yokukhipha amanzi.
5. Sebenzisa umshini wokugaya itshe ukuze ugaye i-convexity ephezulu.
6. Wonke umshini upholishiwe ukuze wakhe indawo ebushelelezi, ehlanzekile futhi emagebhugebhu, kulula ukuyibopha ngokuqinile isisekelo.
Usimende:
1. Hlola ukuthambeka kwesisekelo,
2. Sebenzisa umshini wokugaya itshe ukuze ugaye i-convexity ephezulu,
3. Gcwalisa izindawo zokuhlala eziphansi ngezinto ezisekelwe emanzini,
4. Hlanza, usike futhi upholise inhlanganisela yokwandisa ibe ngumlomo omise okwe-V, ingaphakathi ligcwele imichilo yegwebu futhi ligcwaliswe nge-caulking glue yochwepheshe.
5. Ngemuva kokulinganisa okuphelele, indawo engaphezulu kufanele ivinjwe amanzi ngobuchwepheshe.
Ukufakwa:
Iziphi izinto zezemidlalo okufanele zihlonyiselwe ithrekhi esezingeni elingu-400m nenkundla yenkundla:
I-long jump kanye ne-trip jump
I-Pole Vault
Indilinga yensimbi yeHammer
Isethi Yama-Achor yekheji ye-IAAF evunyelwe ukulahla
Unqenqema olukhiphekayo lwe-aluminium
