A stirring device for geotechnical engineering

Abstract

The invention discloses a stirring device for geotechnical engineering, and belongs to the technical field of engineering machinery. The stirring device comprises a device main body, a fixing platform, a clamping door, a movable platform, a hollow rotating shaft, a conical drill bit, drill rods, rotary blades, sharp drill bits, a rocking rotating shaft, a steel wire rope, a fixed pulley, a metal buckle, a slurry passing pipeline and cement slurry equipment. The slurry passing pipeline and the hollow rotating shaft are combined into a whole through the movable platform, it is ensured that a power system is always located above the ground in the working process of the stirring device for geotechnical engineering, working safety of a motor is ensured, and the service life of the motor can beprolonged; by means of the arrangement of the rocking rotating shaft, the steel wire rope, the fixed pulley and the metal buckle, matching between the fixing platform and the clamping door can be achieved, reasonable splicing of the length of the hollow rotating shaft is achieved according to the pile length, the problem that cement slurry is wasted since a pipeline is too long is avoided, a hollow pipe column can be detached into short sections when cleaning is needed, great convenience is brought to washing work, and the workload of construction staff is reduced.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a stirring device for geotechnical engineering. Background technique [0002] As an effective form of soft foundation treatment, the mixing pile uses cement as the main agent of the curing agent, and uses a geotechnical engineering mixing device to spray the cement into the soil and fully mix it to make a series of physical and chemical reactions between the cement and the soil. In turn, the soft soil hardens to increase the strength of the foundation. After the soft soil matrix is ​​solidified, the next step of construction is generally carried out. Therefore, the working quality of the mixing pile will directly affect the progress and quality of the project. [0003] The power equipment of the stirring device for geotechnical engineering in the prior art needs to go below the ground, but the water below the ground is high, which will cause certain damage to the m...

Problems solved by technology

[0003] The power equipment of the stirring device for geotechnical engineering in the prior art needs to go below the ground, but the water below the ground is high, which will cause certain damage to the motor and shorten the service life of the motor

And the mixing pile device usually used in the prior art has a long grouting pipeline, and the cement slurry will be bonded to the inner wall of the pipeline after the grouting, and the longer the pipeline, the more waste of cement slurry, and cement belongs to cementitious material, so it must be It will condense after a while, so if there is a pause in the middle of the work, the pipeline must be flushed after a certain period of time, otherwise the slurry pipeline will be blocked, but the too long pipeline will bring great inconvenience to the flushing work and it is easy to block the pipeline
