Abstract

The invention relates to a self-pressurization drilling and slurry making integrated deep mixing pile machine and a construction method. The stirring device comprises a rack stably fixed on the ground, a driving mechanism slidably connected to the rack in the vertical direction, a stirring shaft connected to the driving mechanism, stirring blades fixedly connected to the outer bottom of the stirring shaft, a pressure tank fixedly connected to the driving mechanism and additional blades fixedly connected to the stirring blades. Included angles are formed between the axes of the additional blades and the axes of the stirring blades. The device has the effects of reducing the working strength of the driving mechanism and improving the soil layer cutting efficiency.

Description

technical field [0001] The application relates to the field of civil engineering pile drivers, in particular to a self-pressurized drilling and slurry-making integrated deep-mixing pile driver and a construction method. Background technique [0002] Cement mixing pile is an effective form of soft foundation treatment, which is widely used in construction, railway, highway and other engineering fields. the goal of. [0003] At present, the stirring pile driver includes a frame, a driving mechanism that is slidably connected to the frame, a stirring shaft that is rotatably connected to the bottom of the driving mechanism, and a stirring blade that is fixedly connected to the bottom of the stirring shaft. The stirring shaft is provided with an outer shaft and a slurry pipe. The bottom of the shaft is provided with a spray nozzle. The outer shaft is fixedly connected to the output end of the drive mechanism. The drive mechanism drives the outer shaft to rotate. The slurry deliv...
