Diidmada codsiyada birta

Tartanada Ar235 waxaa loogu talagalay codsiyada xirta ee dhexdhexaadka ah halkaas oo ay soo saarto hagaajinta cabashadooda caabbinta ee laxiriira qaraabada qaraabada qaarada qaab-dhismeedka.
● Ar400-ka Ar400 waa iska caddeeyaan taarikada birta ee u adkaysta birta lagu daaweeyo oo lagu soo bandhigo si adag. Hagaajinta iyo awooda guurka.
● Ar450 waa taarikhda loo istcimaalo ee loo isticmaalo codsiyo kala duwan oo xoog yar oo xoog weyn loo doonayo wixii ka dambeeya Ar400.
Plass Pardiyuhu waxay ku habboon yihiin macdan qodista, kaydadka kaymaha iyo codsiyada dhismaha.
● Ar600 waxaa loo adeegsadaa meelo aad u sareeya sida isku-darka ka saarida, macdanta, iyo soo saarista baaldiyo oo dhejiya jirka.
U adkeysiga u adkaysiga (ar) saxan bir ah ayaa sida caadiga ah lagu sameeyaa xaaladdii la duubay. Noocyadan / fasaladan ee alaabada saxan ee birta ah ayaa si gaar ah loogu soo saaray nolosha adeegga dheer ee xaaladaha adag. Alaabada arku waxay ku habboon yihiin codsiyo kaladuwan oo ku saabsan meelaha ay ka mid yihiin minjarka / Quarring, ay soo gudbiyaan, wax ka qabashada qalabka iyo dhismaha, iyo dhulka dhaqaaqa. Naqshadeeyayaasha iyo hawl-wadeyaasha dhirta waxay doortaan bir saxan markii ay ku dadaalayaan in la kordhiyo nolosha adeegga ee qaybaha muhiimka ah, iyo yareynta culeyska cutub kasta oo loo adeegsado adeegga. Faa'iidooyinka loo yaqaan in ay u shaqeeyaan bir bir-u adkaysta ah ee arjiyada ku lug leh saameyn ku yeelata / ama taabashada taabashada ee wax kastoo ka mid ah ma jiraan.

Taargooyinka birta ee is-caabista ah ee loo yaqaan 'aloy' bir bir ah guud ahaan waxay u fidisaa iska caabin wanaagsan si loo istcimaalo oo saameyn ku yeesho xuska. Waxyaabaha kaarboon-sarre ee ku jira alloy waxay kordhisaa adkaanta iyo adkaanta birta, taasoo ka dhigaysa shey ku habboon oo loogu talagalay codsiyada u baahan saameyn sare ama iska caabbinta sare. Waa suurta gal in lagu helo si aad u adag oo leh bir yar oo bir ah, iyo birtu waxay yeelan doonaan iska caabin wanaagsan oo lagu galo. Si kastaba ha noqotee, heerka xijaabka ayaa ah mid dhakhso ah marka loo eego kuleylka saxanka dawooyinka loo daweeyo maxaa yeelay bir yar oo bir yar ayaa jilicsan, markaa waa in walxaha si fudud looga dillaaci karo dusha sare. Sidaas darteed, stelon-yada sare looma isticmaalo codsiyo aad u sarreeya.
