Tube dhalaalaya oo qumman oo qumman
Baabuurta, qaybaha mishiinada, iwm waxay leeyihiin shuruudo sare oo ku saabsan saxnaanta iyo dhamaystirka tuubooyinka birta.Isticmaalayaasha tuubooyinka birta ee saxda ah maaha kaliya isticmaalayaasha kuwaas oo leh shuruudo aad u sarreeya oo sax ah iyo siman.Sababtoo ah saxnaanta saxda ah ee tuubooyinka dhalaalaya ayaa sarreeya, dulqaadkana waxaa lagu hayn karaa fiilooyinka 2--8, isticmaalayaasha mashiinnada badan ayaa badbaadin doona shaqada, alaabta, iyo waqti lumis.Tuubooyinka birta ah ee aan cillad lahayn ama birta wareegsan ayaa si tartiib tartiib ah loogu beddelaa tuubooyinka dhalaalaya ee saxda ah.
Mid:La yaqaan dhexroorka tubbada dhalaalaysa ee aan toosnayn, qeexidda, dhumucda gidaarka si ay u awoodaan in ay xamili karaan habka xisaabinta cadaadiska (xoogga jilicsan ee qalabka birta ee kala duwan ayaa ka duwan)
Cadaadis = ( dhumucdiisuna waxay tahay * 2 * birta birta wax lagu adkaysto)
Labo: Dhexroorka dibadda ee dhuumaha bilaa tolnimada ah ee la yaqaan ee tuubbada birta ah ee aan sinnayn iyo habka xisaabinta dhumucda gidaarka cadaadiska hoostiisa:
Dhumucda gidaarka = (cadaadiska * dhexroorka dibadda * isku xidhka)
Saddex: Habka muujinta isku-xidhka cadaadiska ee tuubbada dhalaalaysa ee aan kala go'a lahayn:
Cadaadiska tuubada birta P<7Mpa coefficient S=8
7
Cadaadiska tuubada birta P>17.5 coefficient S=4
