Nidaamka Barroosinka Is-Qodida Is-qodku wuxuu ka kooban yahay barroosinka barroosinka oo duuduuban oo maran oo leh qoddo cayiman oo fuliya qodista, barroosinka iyo ku-shubista hal qalliin. Nidaamka barroosinka qodista isdifaaca waxaa inta badan loo adeegsadaa xasilinta jiirada, tunnelka taakuleyn horudhac ah, aasaasyo leh iskudhaf yar yar iwm shaqooyin, kaas oo si ballaaran loogu adeegsado macdanta, tunnel, tareenka, metro dhismaha iwm.

Faa'iidooyinka iyo Astaamaha
1. Looma baahna sanduuqyo, maxaa yeelay baararka barroosinka waxaa lagu qodo karaa ciidda dabacsan iyada oo aan loo baahnayn dabool si loo taageero ceelasha.
2. Qodista iyo rakibidda degdegga ah, maxaa yeelay qodista, rakibaadda iyo qodista waxay ku jiraan hawlgal keliya.
3. Labada xarig ee xargaha iyo trapezoid-ka labaduba waa kuwo adag oo ku habboon qodista wareegga wareegga iyo hubinta heer sare oo isku xirnaan leh gout borehole.
4. Xudunta godku uma adeegayso oo keliya in la dhaqo inta lagu jiro qodista, laakiin sidoo kale waxay u adeegsanaysaa ka dib marka la shiido
qodid.
5. Mawduucyo isdaba-joog ah ayaa hubinaya in baararka la jarin karo lana xidhi karo meel kasta, ama la kordhin karo.
6. Qaybaha barroosinka kaladuwan ayaa loo heli karaa xaaladaha dhulka ee kala duwan.
7. Duplex anti-crossion prosess, kulul-maquufin galvanized iyo epoxy nidaamka daahan.
