Description

technical field [0001] The invention relates to a drilling rig, in particular to a cement-soil mixing and stirring drilling rig used in foundation engineering. Background technique [0002] At present, the mixing drilling rig used for soft soil foundation reinforcement is an ordinary mixing drilling rig, which drives the mixing drill bit to rotate and mix through the drill pipe. Since the foundation soil of the soft soil foundation is relatively viscous and adheres to the drill bit, the pile-forming effect is not ideal. Contents of the invention [0003] The present invention makes up for the above shortcomings and provides a cement-soil mixing and stirring drilling rig. [0004] The present invention is achieved through the following technical solutions: [0005] A cement-soil mixing drilling rig, the lower end of the standpipe is fixed with a first cross arm, the left end of the first cross arm is fixed with the upper end of the first vertical arm, the right end of the ...
