Calaamadaha wax soo saarka

Sanadihii ugu dambeeyay, baahida loo qabo tuubooyinka birta birta ee warshadaha kala duwan ayaa si aad ah kordhay. Oo leh koritaanka deg-degga ah ee dhismaha iyo horumarinta kaabayaasha, dhexroorka tuubada tijaabadaayaa noqotay mid weyn oo weyn. Sidaa darteed, baahida loo qabo in tayo sare leh oo tayo sare leh oo caag ah oo ballaadhinta tuubbada birta ah ee birta birta ah ayaa muhiim ah.

Shirkaddayada, waxaan garwaaqnay baahidan sii kordhaya oo waxaan horumarinay xalka ugu sareeya si aan ula kulmo baahiyaha suuqa - tuubbada birta ah ee birta badan. Tuubbadaani gogosha waxaa loogu talagalay in lagu bixiyo awoodda sare ee culeyska sare ee marin-deg-degga biyaha, iyaga oo ka dhigaya qayb muhiim ah oo ka mid ah mashruuca dhismaha badda.

-Eenawareegga tuubbada birta ahwaxaa lagu soo saaray iyadoo la adeegsanayo tikniyoolajiyaddii ugu dambeysay si ay uga hortagto deegaannada ugu daran. Haddii ay tahay dhismaha buundada, dhismaha wadada, dhismayaasha sare ama codsi kasta oo kale oo u baahan aasaas la isku halleyn karo, tuubooyinkayada tijaabada ah ayaa fiican.

Waxa u dhigaya tuubooyinkayada masruufka marka laga reebo waa tayada gaarka ah iyo cimri dheeri. Waxaan fahamsanahay muhiimadda aasaaska adag ee xasilloon, waana sababta aan u galno dhererka weyn si aan u hubinno in tuubbada ugu badan ee birta birta ah ay la kulmaan heerarka ugu sareeya ee heer sare ee heer sare ah. Dhismooyinkooda adag iyo tikniyoolajiyadda horumarsan, tuubooyinkayaga tijaabada ah ayaa loo dhisay inay sii socdaan, iyagoo ku siinaya nabadgelyada maskaxda ee garanaya mashruucaaga waxaa taageera tikniyoolajiyadda ugu fiican ee warshadaha.

Intaa waxaa sii dheer, dhuumahayaga tijaabada ah waxaa lagu heli karaa cabbirro kala duwan si loo haqabtiro baahiyaha gaarka ah ee mashruucaaga. Haddii aad u baahan tahay dhexroor ballaaran oo lagu dhejiyo tuubbada ama cabbir yar, waxaan ku siin karnaa xalka ugufiican shuruudahaaga.

Intaa waxaa sii dheer, waxaan aad ugu faraxsanahay sida ay nooga go'antahay jiritaanka deegaannada deegaanka. Goobahayaga birta ee isgoysyada ah ayaa la soo saaray iyadoo la adeegsanayo hanaanno jawi saaxiibtinimo leh, hubinta in aysan kaliya la kulmin heerarka ugu sareeya ee tayo sare leh laakiin ay sidoo kale u hoggaansamaan qawaaniinta deegaanka adag. Taas macnaheedu waa in markii aad doorato tuubooyinkayada gogosha, kaliya ma maalgashan tahay xalka lagu kalsoonaan karo oo la jaan qaadaya, laakiin sidoo kale waxaad gacan ka geysaneysaa mustaqbal cagaar ah, mustaqbal waara.

Marka la soo koobo, tuubooyinkayada gogoshayada, oo ay ku jiraan gogosha tuubbada birta ee loo yaqaan 'steels birds bir', ayaa ah astaamaha ugu wanaagsan ee warshadaha. Iyada oo ay la socdaan tayada aan kala sooc lahayn, cimri dherer iyo joogto ah, waa doorashada ugu fiican ee mashruuc kasta oo u baahan aasaas la isku halleyn karo. Sidaa darteed, marka ay timaado la kulanka 'Pination Picpe' baahiyahaaga, Shirkadeena ayaa ah doorashadaada ugu fiican. Waxaa naga go'an inaan ku siino xalka ugu wanaagsan dhammaan shuruudahaaga aasaasiga ah.
