Guji badhanka ku yaal Midig
1. Aasaaska Derbiga Saldhigga Hoose:Dhismaha dhulka hoostiisa mara ee dhismayaasha dhaadheer, warshadaha, bakhaarada, dhismayaasha ganacsiga iyo kuwa la dego. Aasaaska tuulmada (nooc kasta oo dhismaha dhismaha ah).
2. Aasaaska Buundada Tuulada:Aasaaska buundooyinka waaweyn, buundooyinka tareenka, iyo buundooyinka magaalooyinka. Aasaaska tuulmada buundooyinka webiyada, harada iyo badweynta.
3. Dhismaha Dekadda:Saldhigga rarka ee terminaalka dekedaha, meelaha maraakiibta la dhigto iyo taarikada dekedda. Qalabka culus iyo adeegyada rarista xamuulka dekedda.
4. Mashruucyada Tamarta Dabaysha iyo Injineernimada Badda ee Xeebaha:Aasaaska matoorada dabaysha ee xeebaha. Naqshadeynta taageerada goobaha xeebaha, dhuumaha badda, dhuumaha badda, derbiyada badda iyo dhanka kale guryaha la deggan yahay. Iska caabbinta hirarka, iska caabbinta hirarka, iyo daxalka badda.
5. Injineeriyadda Madaniga ah ee Cabbirka Weyn:Aasaasyo culus oo leh tuulmooyin ballac ballaaran oo loogu talagalay shaqooyinka injineernimada madaniga ah ee baaxadda weyn (biyo-xireenno, saldhigyada tareenka dhulka hoostiisa mara, iyo godadka). Taageerada mashiinnada warshadaha iyo culaysyada dhismaha.
1) Xafiiska Laanta - Taageerada ku hadasha luqadda Isbaanishka, kaalmada nadiifinta kastamka, iwm.
2) In ka badan 5,000 oo tan oo kayd ah ayaa ku jira kaydka, oo leh cabbirro kala duwan
3) Waxaa baaraya hay'ado awood leh sida CCIC, SGS, BV, iyo TUV, iyadoo la adeegsanayo baakado caadi ah oo badda ku habboon.
1 Baakad:Xariijimo bir ah oo si fudud loo maareeyo. Baloogyada alwaaxa ama dunnage-ka ayaa la dhigaa inta u dhaxaysa rarista si looga hortago isbeddelka xubnaha inta lagu jiro habka rarista. Daawaynta dusha sare (ikhtiyaar): Rinji madow, saliid ka hortagta miridhku, filim balaastig ah. Tuubooyinka galvanized-ka ah ayaa sidoo kale lagu duubi karaa filim balaastig ah oo ku meel gaar ah si looga hortago xoqidda dusha sare. Baakad gaar ah ayaa la heli karaa.
2 Macluumaadka Bixinta:Dhererka Caadiga ah ee Kaydka ku jira: 6m, 12m. Dhererka: Caadiga ah iyo kan caadiga ah. Waxay la socdaan Tareenka Badda iyo Waddada Ku habboon gaadiidka badda, tareenka ama waddooyinka, sidoo kale way ku filan yihiin codsiga waddada. Waqtiga keenista waa 15-30 maalmood ka dib marka la helo lacag bixinta, iyadoo ku xiran tirada iyo qeexitaanka. Waxaa lagu dabaqi karaa dhoofinta caalamiga ah, oo leh dukumeenti buuxa (Shahaadada Imtixaanka, Liiska Baakadaha, Biilka Rarista).
3 Taxaddarrada maaraynta:Ha isticmaalin suuf ama jillaab aan lahayn suuf si aad si toos ah ugu taabato dusha sare ee tuubada taasoo keeni karta isbeddel ku yimaada tuubada. Ku kaydi meel qabow, qalalan oo hawo fiican leh. Si looga fogaado miridhku ka hor inta aan la rakibin. Xamuulka aadka u weyn iyo kuwa cayilan waa inay raacaan xeerarka rarista ee maxalliga ah.

S4: Tuubooyinkan ma lagu daaweeyaa rinji?
Haa - Kuleyl lagu dhex milmay, Epoxy lagu dahaadhay ama lagu rinjiyeeyay Ilaalinta Daxalka.
S5: Waa maxay nooca shahaadada la bixiyo?
Dhammaan tuulmooyinka waxaa ku jira kormeerka dhinac saddexaad ee MTC.
S6: Sidee loo soo raray tuulmooyinka?
Waxaa lagu xiray suumanka birta ah
Bixinta badan ama baaldiyada alwaaxa ah.
Iyada oo leh daboolo dhammaadka iyo daaweynta ka hortagga miridhku
Q7: Ma heli karaa cabbirro gaar ah?
Haa, waxaan ku siin karnaa dhexroor gaar ah, dherer iyo darajooyin loogu talagalay mashruucaaga.
S8: Sidee loo dooran karaa darajada saxda ah?
Iyada oo ku saleysan awoodda culeyska, xaaladda ciidda iyo isticmaalka dhismaha. Taageerada injineernimada.
Q9: Waa maxay wakhtiga keenista caadiga ah?
15-30 maalmood, iyadoo ku xiran tirada iyo habaynta.
