Stirring structure for solidifying slurry residue soil at empty pile section of cast-in-place pile
The invention relates to the technical field of cast-in-place pile construction, and discloses a stirring structure for curing slurry residue soil of an empty pile section of a cast-in-place pile, the stirring structure comprises an excavator for removing an excavator bucket, the excavator comprises a movable machine body and a swing arm, a power head is hinged to the swing arm, a stirring drill rod is connected to the power head, and a stirring drill bit is arranged at the bottom of the stirring drill rod; the periphery of the lower section is movably sleeved with a hollowed-out cylinder, and the hollowed-out cylinder is movably connected with the lower section. The power head drives the stirring drill rod and the stirring drill bit to rotate synchronously, the slurry outlet holes eject solidified slurry, the gas outlet ejects high-pressure gas, the drill rod blades and the drill bit blades stir slurry muck and the solidified slurry synchronously, and the hollow cylinder is in a free state and is extruded by the slurry muck to rotate. The slurry and the slurry muck are stirred and solidified, high-pressure gas is sprayed out, the slurry muck is rapidly solidified, the strength of undisturbed soil can be achieved in a short time, and then normal walking of mechanical equipment in a construction site is guaranteed.
本发明涉及灌注桩施工的技术领域，公开了用于灌注桩空桩段泥浆渣土固化的搅拌结构，包括拆除挖斗的挖掘机，挖掘机包括移动的机体以及摆动臂，摆动臂上铰接有动力头，动力头上连接有搅拌钻杆，搅拌钻杆的底部设有搅拌钻头；下部段的外周活动套设有镂空筒，镂空筒与下部段活动连接；动力头驱动搅拌钻杆以及搅拌钻头同步转动，出浆孔喷出固化浆液，出气口喷出高压气体，钻杆叶片以及钻头叶片搅拌同步搅拌泥浆渣土与固化浆液，镂空筒处于自由状态，受泥浆渣土挤压转动。通过搅拌固化浆液与泥浆渣土并喷出高压气体，使泥浆渣土快速固化，在短时间内可以达到原状土的强度，进而保证施工场地机械设备正常行走。
