Hordhac Guud:
Nidaamka barroosinka bannaan ee iskii u qodaya waxa uu ka kooban yahay bir dun godan oo ay ku dheggan tahay wax qodista oo samayn kara qodista, barroosinka iyo xoqidda hal hawlgal. Barta bannaan waxay u ogolaataa hawada iyo biyaha inay si xor ah u dhex maraan baarka inta lagu jiro qodista si meesha looga saaro wasakhda ka dibna u oggolaadaan in qashinka la isku duro isla marka la dhammeeyo qodista. Grout waxay buuxisay bar godan oo waxay si buuxda u dabooshaa daboolka oo dhan. Isku-xidhyada waxa loo isticmaali karaa in lagu xidho baararka godan oo la dheereeyo dhererka boodhka halka looska iyo taarikada loo isticmaalo si loo bixiyo xiisadda loo baahan yahay.
Nadaamka barroosinka bar godan ee is-qodista ayaa ah habka ugu badan ee loo isticmaalo xasilinta tirada dhagaxyada, gaar ahaan tunnel-ka, macdanta dhulka hoostiisa iyo warshadaha injineernimada dhulka. Waxaa inta badan loo adeegsadaa injineernimada kaalmaynta ee dabaqyada dhagxaanta ah ee dabacsan iyo jaban ee ay adagtahay in dalool laga soo qodo. Waxay siisaa xalka ugu fiican ee ciddiyeeynta ciidda, qufulka bolting, xirmooyin yar yar.
Nidaamka barroosinka bannaan ee is-qodista wuxuu buuxiyaa baahida hadda jirta oo sii kordheysa ee tunnelka, warshadaha macdanta iyo injineernimada dhulka ee wax soo saarka badbaado iyo dhaqsaha badan. Nidaamku wuxuu bixiyaa faa'iidooyin dhammaan aagagga codsiyadiisa, halkaas oo ceelasha riigga ah ay u baahan doonaan waqti badan oo lagu qodayo hababka daasadaha ee ciidda aan la adkeyn ama isku xiran.
Tilmaamaha iyo Faa'iidooyinka:
Si gaar ah ugu habboon xaaladaha dhulka ee adag.
Rakibaadda wax-ku-oolka ah tan iyo markii la qoday, meel dhigista iyo grouting waxaa lagu samayn karaa hal hawlgal, iyada oo la badbaadinayo waqti iyo lacag labadaba.
Habka is-qodista ayaa meesha ka saaraysa baahida loo qabo ceel-biyood kiis ka samaysan ee carrada dumaysa.
Hab degdeg ah oo hal-tallaabo ah oo ku xidhidh ah oo leh qalab fudud oo awood u leh inuu ku shaqeeyo dalool-raadiska caadiga ah (dubbada sare) ama qalabka wax lagu qodo ee gacanta lagu hayo, taasoo meesha ka saaraysa baahida qalabyada daasadaha ee waaweyn.
Rakibaadda la qodida isku mar ah iyo grouting suurto gal, iyo post grouting nidaamka waa mid fudud.
Qulqulka joogtada ah iyo daloolista cadaadiska sare ayaa sababa in groutku uu dhex maro carrada dabacsan oo abuurta nalka-saamaynta kororka awoodda curaarta.
Ku rakibida fudud ee jihooyinka oo dhan, sidoo kale kor u kaca, iyo hababka rakibida la midka ah ee dhammaan xaaladaha dhulka.
Ku habboon in lagu shaqeeyo meel xaddidan, dhererka iyo meelaha ay adagtahay gelitaanka.
Galvanizing si kor loogu qaado ilaalinta daxalka ayaa diyaar ah haddii loo baahdo.
Noocyo badan oo dhar-dhibcood ah oo ku habboon xaaladaha dhulka ee kala duwan.
Qaabka dunta si joogto ah u xidhan waa la gooyn karaa oo lagu dhejin karaa meel kasta oo dhererkeeda ah si loo gaadho dhammaan dhererka.
