Uyilo loMzobo
400M imfuneko:
Ukwenziwa kweSiseko
Iimfuno zesiseko se-asphalt
Izixhobo zokuhambisa amanzi
Ufakelo lweendawo ezizinzisiweyo:
I-asphalt yeeMfuno zoMphezulu oSisiseko:
1. Sebenzisa izinto ezisisiseko samanzi ukutywina umgangatho wesiseko kwaye uvale izikhewu kwikhonkrithi ye-asphalt.
2. Yenza uvavanyo lokunkcenkceshela ukufumanisa ukudakumba.
3. Sebenzisa izinto ezisisiseko samanzi ukuze ugcwalise i-depressions ephantsi, kwaye usebenzise ixesha elide kunemveliso.
Ibha ethe tye enobubanzi bamanzi obu-2m kufuneka ichithwe ngokuphindaphindiweyo ngaphandle kwamaqhuma.amaza ajikelezayo.
4. Zama ukwenza ithambeka ngokwendlela yokuhambisa amanzi.
5. Sebenzisa i-grinder yamatye ukugaya i-convexity ephezulu.
6. Umatshini wonke upholishiwe ukwenza umphezulu ogudileyo, ococekileyo kunye norhabaxa, kulula ukubopha umphezulu wesiseko ngokuqinileyo.
Isamente:
1. Jonga ukuthe tyaba kwesiseko,
2. Sebenzisa igrinder yelitye ukugaya i-convexity ephezulu,
3. Gcwalisa iindawo zokuhlala eziphantsi ngezinto ezisekelwe emanzini,
4. Ukucoca, unqumle kwaye upholise umdibaniso wokwandisa kumlomo owenziwe nge-V, ingaphakathi lizaliswe ngamacwecwe e-foam kwaye izaliswe yi-caulking glue yobuchwephesha.
5. Emva komgangatho opheleleyo, umphezulu kufuneka ukhuselwe ngobuchule ngamanzi.
Ukuhlohla:
Zeziphi izixhobo zemidlalo ekufuneka zixhotyiselwe umkhondo we-400m oqhelekileyo kunye nebala lebala:
Umtsi omde kunye nokutsiba uhambo
I-Pole Vault
Isangqa Metal for Hammer
Iseti yeeAchors ze-IAAF ezivunyiweyo zokulahla ikheji
I-Aluminiyam enokugutyungelwa umphetho
