IModel Hm4d-0006E isithintelo esizenzekelayo sesikhukula se-hydrodynamic siyasebenza ekungeneni nasekuphumeni kwizikhululo zikaloliwe ezingaphantsi komhlaba okanye zemetro apho kuvumeleke abahambi ngeenyawo kuphela.
(1) Indawo yokufaka umphezulu
a) Imalunga ne-5cm ukuphakama ukusuka emhlabeni. Kufuneka ukuthintela ukukrwela umzantsi wesithuthi xa isithuthi sigcwele ngokupheleleyo. Xa imoto ilayishwe ngokupheleleyo, ubuncinci bemvume yomhlaba: iPentium B70 = 95mm, i-Honda Accord = 100mm, iFeidu = 105mm, njl.
b))Indawo kufuneka ibekwindawo ethe tyaba kumphezulu wethambeka, ngaphakathi komsele wokucanda ongaphandle, okanye ifakwe kumsele wokucanda. Izizathu: amanzi amancinci anokukhutshwa ngomsele wokuvalela; inokuthintela ukubuya umva ekuvaleni umsele emva kokuba umbhobho kamasipala ugcwele.
c)Xa iphezulu indawo yofakelo, kokukhona inyuka inqanaba lokugcina amanzi.
(1) Umgangatho womgangatho wofakelo
a) Umphezulu wofakelo umahluko wobude obuthe tye ekupheleni kodonga kumacala omabini ≤ 30mm (ilinganiswa ngemitha yenqanaba lelaser)
(2) Ukuthe tyaba komphezulu wofakelo
a) Ngokwekhowudi yokwamkelwa komgangatho wolwakhiwo wobunjineli bomhlaba wokwakha (GB 50209-2010), ukutenxa komphezulu we-flatness kuya kuba ≤ 2mm (kulinganiswa nge-2m yesikhokhelo somgaqo kunye ne-wedge feeler gauge), ngaphandle koko, umhlaba uya kuphakanyiswa kuqala, okanye isakhelo esisezantsi siya kuvuza emva kofakelo.
b) Ngokukodwa, umhlaba ononyango oluchasene nokutyibilika uya kunyuswa kuqala.
