Tiis bir ah oo balaaran oo qandaraas ku jira heerkulka sare ama hooseeya, laakiin heerkulka gaarka ah wuxuu kuxiran yahay tuubbada aaladda iyo xaaladaha deegaanka.
1. Mabaadi'da fiditaanka tuubbada birta ah iyo foosha
Qulqulka tuubbada birta iyo foosha waxaa sababa guryaha ku dhaca kuleylka iyo foosha ee birta: heerkulka sare, tuubbada hoose, iyo heerkulka hoose, ayaa mar labaad qandaraas qaadata. Sidaa darteed, heerkul gaar ah, tuubooyin bir ah ayaa balaaran oo qandaraas ku dhaca.
2. Saamaynta saamaynta
1). Steel tuubbada Steel
Tuubbooyinka birta ee agabyada kaladuwan ayaa u adkeysan kara heerkulka kala duwan. Tusaale ahaan, tuubooyin bir ah oo caadi ah oo bir ah ayaa leh awood sare oo ka sareeya ballaarinta heerkulka sare, taasoo ka dhigeysa inay u nugul yihiin cilad, ballaarinta, iyo dillaaca. High {-} bir bir ah oo bir ah, dhinaca kale, waxay u adkeysan karaan heerkulka sare.
2). Jawigu heerkulka
Heerka ballaarinta iyo foosha ee tuubooyinka birta waxaa sidoo kale saameyn ku leh jawiga heerkulka birta, maadaama xadka ballaarinta iyo foosha ay u dhigantaa baaxadda isbedelka heerkulka. Xagga sare {{} {{} {} {{1 {}}, dhuumaha birta balaaran. Meel hooseeya {{17}}, waxay qandaraas qaadanayaan oo xitaa way noqon karaan kuwo aad u burbursan.
3. Ka hortagga
1). Si habboon u xulo shey bir ah
Tuubbooyinka birta waa in laga sameeyaa agabyo munaasib ah oo ku saleysan jawiga dhabta ah ee hawlgalka, hubinta in tirada qandaraaskooda heerkulka ay buuxiyaan shuruudaha dhabta ah.
2). Naqshadeynta hab rakibaadda saxda ah
Inta lagu gudajiro rakibaadda, taageerada habboon iyo qaababka hagaajinta waa in loo istcimaalaa si looga hortago cilad, dillaac, ama kala tagga isku xirka iskuxirka iyo foosha darteed.
3). Saadaalin ballaarinta kuleylka
Inta lagu guda jiro howsha naqshadeynta injineernimada, ballaarinta kuleylka ee tuubooyinka birta waa in la saadaaliyaa. Dhibaatooyinka sababi kara niyad-jab iyo jabinta waa in wax laga qabtaa lagana hortagaa horumarka.
4). Samee kormeer joogto ah iyo dayactir
Samee baaris joogto ah iyo dayactirka tuubooyinka birta, oo wax ka qabashada wixii dhibaatooyin ah si dhakhso leh si loo yareeyo khataraha amniga ee ay sababaan arrimaha tayada leh ama waqti dheer {}}}.
