Sharaxaada Alaabta

Naqshado saqafka wax lagu qodayo waa bilal si gaar ah loo qaabeeyey oo inta badan loo isticmaalo codsiyada saqafka. Muruqyadan waxaa lagu sameeyaa meel fiiqan oo u oggolaanaysa inay ku dhex qodaan alaabta saqafka ah sida birta, balaastigga, ama alwaax iyada oo aan loo baahnayn dalool horay loo sii qoday. Boolalku waxay ka kooban yihiin madax hex ah ama madaxa wax dhaqda kaas oo siinaya xidhiidh sugan oo ka dhexeeya alaabta saqafka iyo sagxada saqafka.

Naqshadaynta saqafka is-daaqidda waxay caadi ahaan ka samaysan yihiin bir aan lahayn ama bir galvanized ah, taasoo siinaysa iska caabin sare oo ay u leeyihiin daxalka iyo miridhku. Boolalku waxay leeyihiin cabbir iyo dherer kala duwan, waxaana loogu talagalay inay u adkeystaan xaaladaha cimilada adag ee saqafyada ay la kulmaan.

Mid ka mid ah sifooyinka gaarka ah ee istaroojiyeyaasha saqafka saqafka ah ayaa ah awoodda ay u leeyihiin inay abuuraan shaabad biyo-celin ah oo ku wareegsan daloolka furaha. Taas waxaa lagu gaaraa caag ama neoprene dhaqe kaas oo lagu rakibay madaxa furka hoostiisa, kaas oo daboolaya daloolka kana hortagaya in biyuhu ka soo dhex baxaan.
