Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described in detail, it is to be understood that this
The protection domain of invention is not limited by detailed description of the invention.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " bag
Include " or its conversion as " comprising " or " including " etc. will be understood to comprise stated element or
Ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 1 to Figure 3, according to a kind of barb grouting formula anchor pole of the specific embodiment of the invention,
Including the body of rod 1, barb plate 2 and push rod 3.The body of rod 1 is internal, and in cavity structure, cavity is used for accommodating slurry,
The front end of the body of rod 1 is conehead structure.The mobilizable front portion being located at the described body of rod 1 of barb plate 2.Preferably
Ground, barb plate 2 is 4 pieces, and uniform ring is set around the outer surface of the described body of rod 1.Push rod 3 and barb plate 2
