Abstract

Abstract

Twin jet-grouting technology with dual-rod (TDR) is a useful approach to solidify the soft soil instantly, in which accelerator is used to mixing with cement slurry. The main equipments of twin jet-grouting include a high pressure cement pump,a accelerator pump,a diverter,a drilling rod,a drill rig,and a multifunctional injection monitor with two nozzles,through which the high pressure cement slurry is jetted out from the upper nozzle,eroding soil,and the accelerator shrouded the high pressure cement slurry is jetted from the lower nozzle,mixing with the eroded soil. Therefore,the admixture can gel within several seconds. TDR has the possibility of wide applications for its instant solidification of soft sandy soil with much groundwater.
