Tuubbooyinka dharka lagu dhejiyo ee loogu talagalay safka gaaska dabiiciga ah ee dhulka hoostiisa
Tuubooyinka dharka lagu dhejiyowaxay muhiim u yihiin warshadaha, gaar ahaan dhismaha dhuumaha saliida iyo gaaska. Faahfaahintooda waxaa lagu muujiyaa dhexroor dhexroor ah iyo dhumucdii derbiga, oo muujinaya awooddooda iyo laqabsashada baahiyo kala duwan oo tuubooyin ah.

Geedi socodka waxsoosaarka ee tuubbada dharka lagu dhaqo oo ku jira adeegsiga tikniyoolajiyadda yar yar ee tikniyoolajiyadda, soo saarista tuubooyinka hal-geesoodka ah ama laba-dhinac ah. Hawlahan alxanka ah waxay xaqiijinayaan cimri dhererka ugu sarreeya iyo isku halaynta dhuumaha, oo awood u leh in ka dhasho kuwa qalalaasahaKhadka Gas ee Dhulka Dhexegudbinta.
Xaruntayaga wax soo saarka, waxaan dammaanad ka qaadaynaa in tuubooyinkayaga khaaska ah ee is-wareejinta ay mariyeen tijaabada hubinta tayada tayada ee adag si loo hubiyo heerarkooda waxqabadka sare. Waa wax muhiim ah in biibiilaha quseeya uu la kulmo qawaaniinta loogu talagalay baaritaanka hydralic, xoogga khafiifka ah iyo guryaha la jeexjeexa.
Tuubbadayada quseysa ee qunyar-socodka ah waxaa loogu talagalay in lagu daro heerarka warshadaha oo ay ka soo baxaan shuruudaha ugu adag ee nidaamyada isu gudbinta ee safka hoose ee safka dhulka hoostiisa. Waxaa loogu talagalay in ay ka hortagaan xaalado badan oo deegaanka ah, hubinta cimri dheer iyo nabadgalyo muddo-dheer codsi kasta.
Codsiga tuubooyinka dhuumanaha ee khafiifka ah ee ku jira xargaha gaaska dabiiciga ee gaaska ee dhulka hoostiisa ayaa bixiya hab wax ku ool ah oo hufan oo loogu talagalay gaadiidka gaaska dabiiciga ah. Meesha laga dhaxlo dhismayaasha go'doomineed ayaa hubiya in gaarsiinta gaaska uuna yareeyo halista daadashada ama gogosha waqti ka dib, iyada oo nabadu ay u siiso xasilloonida dadka ka shaqeeya iyo isticmaaleyaasha dhamaadka.
Waxaa naga go'an inaan siino macaamiisheenna alaabada tayada ugu sareysa, tuubooyinkayaga oo qunyar socod ahna waa marag u ah sida ay nooga go'antahay heerkeena sare ee warshadaha. Waxaan mudnaanta siinnaa cimri dhererka, waxqabadka iyo badbaadada alaabadayada, hubinta inay la kulmaan oo ka badan yihiin shuruudaha adag ee nidaamyada gudbinta ee gaaska dabiiciga ah.
Marka la soo koobo, tuubooyinkayaga qunyar-socodka ah ee is-afgaradka waa qayb lama huraan ah oo ku saabsan dhismaha iyo dayactirka nidaamyada gaadiidka caadiga ah ee gaaska ee dhulka hoostiisa. Iyada oo dhismaheeda sareeya, u hoggaansanaanta heerarka warshadaha, iyo ballanqaadka aan kala go 'lahayn ee tayada, biibiilahayaga wareega ee is-wareejinta ayaa ku habboon mashruuca gaaska gaaska dabiiciga ah. Iyada la wadaago annaga oo nagala shaqeeya si aan u bixinno tuubbada ugu sareysa ee tayada ugu sareeya ee loogu talagalay baahiyaha gudbinta dhuumaha gaaska ee dhulka hoostiisa.
