    Sharaxaad Gaaban:

    Soo bandhigida tuubooyinka birta ah ee cusub ee SSAW, oo ah badeecad tayo sare leh oo loogu talagalay adeegyo kala duwan, gaar ahaan dhuumaha gaaska dabiiciga ah ee dhulka hoostiisa mara. Tuubadan khadka ah ee X65 SSAW waxaa si weyn loogu isticmaalaa dhuumaha gaadiidka dareeraha ah ee alxanka, qaab-dhismeedka birta, aasaaska tuulmada, iwm. Iyada oo leh waxqabad sare iyo cimri dherer, badeecadan waxaa loo arkaa mid lagama maarmaan u ah warshadaha iyo mashaariicda kaabayaasha dhaqaalaha kala duwan.


    Faahfaahinta Badeecada

    Calaamadaha Alaabta

    Tuubooyinka laalaada ee dhulka hoostiisa mara waa qayb muhiim ah oo ka mid ah injineernimada biyaha, warshadaha batroolka, warshadaha kiimikada, warshadaha korontada, waraabka beeraha, iyo dhismaha magaalooyinka. Kala duwanaanshaheeda iyo isku hallaynteeda ayaa ka dhigtay mid ka mid ah labaatanka badeecadood ee muhiimka ah ee laga sameeyay dalkeenna, taasoo muujinaysa muhiimaddeeda iyo saameynta ay ku leedahay warshadaha kala duwan.

    tuubo bir ah oo SSAW ahWaxaa loo sameeyay si gaar ah loogu qaado dareeraha, waana mid ku habboon bixinta biyaha iyo nidaamyada dheecaanka. Dhismaheeda adag ayaa ka dhigaya mid ku habboon hubinta wareejinta dareeraha oo hufan oo la isku halleyn karo. Intaa waxaa dheer, waxay sidoo kale ku habboon tahay gaadiidka gaaska sida gaaska dhuxusha, uumiga, iyo gaaska batroolka dareeraha ah. Awooddeeda sare ee la jiidi karo iyo iska caabbinta daxalka waxay hubineysaa keenista gaaska oo ammaan ah oo hufan waxayna buuxineysaa shuruudaha adag ee nidaamyada keenista gaaska.
