Dhuumaha birta go'an waa hab horay loo sii aasay oo tuubooyinka jeexjeexa sida caadiga ah loo isticmaalo in si joogto ah loo xidho kala-goysyada dhismaha, kala-goysyada qabowga, kala-goysyada tuubooyinka jeexjeexyada iyo farqiga u dhexeeya darbiyada dhulka hoostiisa ee shubka ah. Waxay ka caawisaa in ay xoojiso xoog cadaadis iyo seismic ee aasaaska raso. Aad bay ugu habboon tahay in la rakibo tuubooyinka grouting inta u dhaxaysa kala-goysyada shubka ah iyo kuwa cusub. Grouting waxay u baahan tahay isticmaalka qalabka grouting, dhexda tuubooyinka grouting iyo madax tuubooyinka grouting, kuwaas oo hawshooda ugu weyni waa in ay ka caawiyaan shubka shubka kala goysyada shaqsi si ay si buuxda u shaabadeeyey karaa, sidaas darteed ka hortagga jabka, barokaca iyo qallooca, iyo si fiican u ilaalinaya aasaaska raso. iyo agabka rarka.

Noocyada Tubooyinka Birta Goynta
Tuubooyinka birta grouting waxay u kala qaybsan yihiin tuubooyinka grouting la tuuri karo ( CCLL-Y tuubada grouting, QDM-IT tuubada grouting, CCLL-Y tuubooyinka grouting qayb buuxda) iyo tuubooyinka grouting soo noqnoqda (CCLL-D tuubooyinka grouting, CCLL-D qayb buuxda grouting tuubada) . Dhuumaha qashinka ee hal mar ah waxaa la nuugi karaa hal mar oo dib looma isticmaali karo. Tuubbooyinka soo noqnoqda ee soo noqnoqda ayaa dib loo isticmaali karaa dhowr jeer, iyo xuddunta iyo derbiga dibadda ee tuubada waxay u baahan yihiin in la dhaqo nadiif ah ka dib isticmaal kasta.
Faa'iidooyinka Gudaynta Tuubooyinka Birta
Tuubooyinka birta jeexjeexa waxay leeyihiin adkeysi wanaagsan waxayna xirtaan caabbinta, waxaana la isticmaali karaa waqti dheer. Intaa waxaa dheer, waxay sidoo kale leedahay awood cadaadis wanaagsan iyo iska caabin saameyn leh, waxayna u adkeysan kartaa cadaadis weyn. Tuubbada birta birta ah waxay sidoo kale leedahay dahaar wanaagsan iyo waxqabadka daboolka dhawaaqa, kaas oo si wax ku ool ah uga ilaalin kara dhuumaha saamaynta heerkulka dibadda.
