The invention relates to the technical field of open
caisson construction equipment, in particular to open
caisson stirring and sucking equipment which comprises a
machine shell, a stirring and crushing
assembly, a
slurry discharging
pipe, an
underwater propeller and a posture stabilizing device, the posture stabilizing device comprises a transverse moving
assembly and a lifting
assembly, and the transverse moving assembly is used for controlling the
machine shell to move along a preset track when the
machine shell is pushed by the
underwater propeller; by arranging the
underwater propeller and the stirring and crushing assembly, transverse soil sampling is achieved, the construction blind area is reduced, the smashed soil layer
slurry is pumped through the
slurry discharging
pipe, the sinking posture of the open
caisson and the sinking speed of all positions are accurately controlled, and the construction efficiency is improved; by arranging the posture stabilizing device, it is guaranteed that the
drill bit stably and transversely moves and perpendicularly abuts against the working face in the construction process, the
drill bit is not prone to swinging in the stirring and sucking process, and the working efficiency and the
engineering quality in the stirring and sucking process are improved; and the lifting assembly is folded, a gear lever limits movement of a sliding block, the positions of the machine shell and the posture stabilizing device are relatively fixed, and the equipment construction position is finely adjusted through an underwater propeller.
