Dulmar guud ee Dhuumaha birta Grouting for Bridge Pile Foundation
Dhuumaha birta gooyaa waa qalab si weyn loo isticmaalo sida dhismaha, tunnel-yada, iyo injineernimada dhulka hoostiisa. Shaqadeeda ugu weyni waa in ay ku durto walxaha grouting godadka dhulka hoostiisa, buuxisa daldaloolada, oo ay wanaajiso awoodda iyo xasiloonida aasaaska. Tuubooyinka Grouting waxay leeyihiin faa'iidooyinka qaab dhismeedka fudud, dhismo ku habboon, iyo saameyn weyn, sidaas darteed si weyn ayaa loogu isticmaalay injineernimada dhulka hoostiisa.

Codsiga tuubooyinka birta grouting
Dhuumaha birta grouting waa wax caadi ahaan loo isticmaalo dhuumaha, si weyn loogu isticmaalo warshadaha, ilaalinta biyaha, dhismaha, ilaalinta dabka, iyo beeraha kale. Waxay leedahay iska caabin daxalka wanaagsan iyo xirashada iska caabin ah, oo waxay leedahay xoog cadaadis gaar ah.
Tuubooyinka birta soo saara waxay inta badan ka samaysan yihiin bir aan lahayn, sidaas darteed waxay leeyihiin iska caabin daxalka oo wanaagsan. Intaa waxaa dheer, tuubada birta birta ah waxay sidoo kale leedahay xoogaa cadaadis ah waxayna u adkeysan kartaa cadad cayiman. Intaa waxaa dheer, tuubada birta birta ayaa sidoo kale leh caabbinta xirashada waxaana loo isticmaali karaa waqti dheer.
