Description

Anti-blocking air injection device for cement mixing pile

Technical Field

The utility model relates to a cement mixing stake machine field, concretely relates to cement mixing stake prevents stifled air jet system.

Background

The mixing pile is divided into a slurry mixing pile and a powder mixing pile according to different states of the reinforcing material, and is divided into a one-way cement mixing pile and a multi-way cement mixing pile according to different mixing directions of blades of the construction machine. Although the construction technology is mature, a plurality of adverse factors exist in the construction process.

Firstly, the technological requirement of stirring and drilling to the designed depth is that blades of a drill rod fully stir and loosen the underground undisturbed soil, but in the actual construction process, because a nozzle at the front end of a grouting pipe is connected with a drill bit, no matter drilling or lifting is carried out, the drill bit cannot be blocked, and the grouting or water spraying must be continuously carried out in the construction process, otherwise, drilling sludge is very easy to block a grouting hole, so that the grouting cannot be carried out; if the slurry is continuously sprayed, the four-spraying and four-stirring process is adopted, the slurry spraying amount is increased, and the cost is multiplied; if the water spraying process is adopted, the process is connected with the problem, the water content of the foundation can be increased, and the pile forming quality is influenced to a certain extent.

No matter the cement mixing pile machine on the existing market is used for spraying mortar or water, other negative effects can be brought. Such as: in the drilling process, undisturbed soil is not sufficiently loosened, and slurry or water is directly mixed with a soil body, so that the soil body is coagulated into blocks and cannot be uniformly stirred and uniformly sprayed. If the slurry is continuously sprayed, excessive slurry is discharged to a construction site in the displacement process of the drilling machine, drilling difficulty of the drilling machine is increased after the cement slurry on the surface of the site is solidified, and the slurry flows to a peripheral site to cause serious pollution to the environment. If the water spray, also will lead to muddy not enough in the place, because of the rig is by four landing legs atress all the time at the in-process that shifts, the weak inequality in place has brought certain risk for construction safety, can increase construction material cost simultaneously.

Therefore, it is necessary to provide an anti-blocking air injection device for cement mixing piles to solve the above problems.
