Dhuumaha Bir Madow
Bir madow:
Birta madow waa birta aan dahaarka lahayn waxaana sidoo kale loo yaqaannaa birta madow.Marka dhuumaha birta ah la been abuurto, miisaan madow ayaa ka sameysma oogada sare si ay u siiso dhamaadka kaas oo lagu arko tuubada noocaan ah.Sababtoo ah birta madow waxay ku xiran tahay miridhku iyo daxalka, warshadda sidoo kale waxay ku dahaadhaa saliid difaac ah.Birahaas madow waxaa loo isticmaalaa tuubooyinka iyo tuubada wax soo saarka, kuwaas oo aan daxalaysan doonin muddo dheer oo u baahan dayactir aad u yar.Waxaa lagu iibiyaa heerka caadiga ah ee dhererka 21-foot TBE.
Isticmaalka dhuumaha birta madow ::
Dhuumaha birta madow ayaa si weyn loogu dabaqi karaa isticmaalka caadiga ah ee biyaha, gaaska, hawada iyo uumiga, tuubooyinka birta madow iyo tuubooyinka waxaa loo isticmaalaa qaybinta gaaska gudaha iyo dibadda guriga iyo wareegga biyaha kulul ee hababka kuleyliyaha.Waxa kale oo loo isticmaalaa tuubooyinka khadka ee warshadaha saliidda iyo batroolka, ceelasha biyaha iyo ujeedooyinka biyaha, gaaska iyo wasakhda.Looma isticmaalo biyaha la cabbi karo ama qashinka bullaacadaha ama khadadka hawo-mareenka.
Dhuumaha birta madow:
Tuubooyinka birta madow iyo tuubooyinka waa la gooyaa oo dunta lagu dhejiyaa si ay ugu habboonaadaan shaqada.Qalabka tuubooyinka noocaan ah ayaa ah bir shub ah oo malleable (jilicsan).Waxay isku xiraan iyagoo ku dhejinaya tuubada dunta leh, ka dib markay ku dhejiyaan xaddi yar oo isku-dhafka tuubada ah ee dunta.Dhuumaha dhexroorka ka weyn ayaa la alxanayaa halkii dunta laga saari lahaa.Dhuumaha birta madow waxaa lagu gooyaa tuubo-jare culus ama miinshaar la jaray ama hacksaw.Marka dhuumaha birta ah la been abuurto, miisaan madow ayaa ka sameysma oogada sare si ay u siiso dhamaadka kaas oo lagu arko tuubada noocaan ah.Sababtoo ah birta waxay ku xiran tahay miridhku iyo daxalka, warshadda waxay sidoo kale ku dahaadhaa saliid difaac ah.Birahaas madow waxaa loo isticmaalaa tuubooyinka iyo tuubada wax soo saarka, kuwaas oo aan daxalaysan doonin muddo dheer oo u baahan dayactir aad u yar.Waxaa lagu iibiyaa heerka caadiga ah ee dhererka 21-foot TBE.
