Qulqulka barroosinka
Daboolka barroosinka macneheedu waa ul u wareejisa dhismayaasha ama culeyska juqraafiyeed dhagax deggan
samaynta, waxa ay ka kooban tahay ul, birta laydhka, isku xidhka, saxan, stoper grouting iyo lowska.Waxa uu ahaa
si weyn loogu isticmaalo tunnling, macdanta, xasilinta jiirada, daaweynta cudurrada tunnel-ka iyo taageeridda saqafka
ee shaqada dhulka hoostiisa.Waxaa loogu talagalay dhulka dabacsan (dhoobo, ciid friable iwm.) Usha barroosinka godan ayaa laga sameeyay
tuubo aan kala go 'lahayn oo leh xoog sare.
Astaamaha boodhka barroosinka godan
• Si gaar ah ugu habboon xaaladaha dhulka ee adag.
Heerka sare ee rakibaadda tan iyo markii la qoday, meel dhigista iyo grouting waxaa lagu samayn karaa hal qalliin.
• Habka is-qodidda ayaa meesha ka saaraya baahida loo qabo ceel-biyood kiis ah.
• Ku rakibida qodida iyo grouting isku mar ah oo suurtogal ah.
• Ku rakibid fudud dhammaan jihooyinka, sidoo kale kor.
Ku habboon in lagu shaqeeyo meel xaddidan, dhererka iyo meelaha ay adagtahay gelitaanka.
• Nidaamka grouting post fudud.• Galvanization-kululeed si loo ilaaliyo daxalka
Codsiyada Tunneling & Ground Engineering
• Daboolista shucaaca
• Dejinta jiirada
• Kahortagista
• Tusmada irbado yar yar
• Dejinta wajiga
• Barroosinka taageerada ku meel gaadhka ah
• Diyaarinta Xariirka
• Ciddida ciidda
