It is more than leaf.
Further, the cross-cutting blade is equipped with cutting edge along rotation direction of advance side, and cutting edge has certain inclination angle, tendency rotation
Direction.
Further, the cross-cutting blade of each leaf is axially integral or segmented is arranged, the revolving knife being axially integral
Piece is connected with the mixing blade being spaced apart, and axial is the cross-cutting blade that segmented is arranged and the mixing blade being spaced apart
It connects one by one, interruption is equipped between the cross-cutting blade of adjacent leaf.
Further, there is grout outlet in incision mixing blade upper end surface.
Cross blade is arranged in drilling rod shaft in the utility model, increases the uniformity of pile body stirring.And it is set in drilling rod shaft
Vertical crosscutting blade is set, makes drilling rod that there is transverse shifting to cut agitating function, can back transverse shifting be taken by rigid stirring pile body
The place of connecing is stirred, can also back move carry out encryption whitewashing stirring, be significantly greatly increased Soil-cement Wall continuity and
Even property reduces entire cement soil wall " jag " phenomenon.
Detailed description of the invention
Fig. 1 is the blade jackrod structure schematic diagram of the utility model embodiment.
Fig. 2 is the A of the utility model embodiment --- A diagrammatic cross-section.
Specific embodiment
Detailed descriptionthe is carried out to the utility model below with reference to embodiment and attached drawing.
Embodiment 1,
Drilling rod is made of light round bur bar (hereinafter referred to as round bur bar) and band blade drilling rod (hereinafter referred to as blade drilling rod), each to bore
Bar top is connected through a screw thread with vertical shaft, as vertical shaft rotates together and slides up and down.
To be easily installed and dismantling, every drilling rod is divided into several sections, and every section drilling rod is connected by screw thread.Every drilling rod
On blade run of steel it is equal, size be equal to or slightly less than run of steel tolerance, the tolerance be equal to design stirring depth divided by
Drilling rod number has cross-cutting blade part, it can be provided be made of several sections, often for the blade drilling rod convenient for assembling different length
Section is connected by screw thread.
Round bur bar is same as the prior art, is hollow cylindrical drilling rod, does not have agitating function, effect is extension arm.Such as
Shown in figure, blade drilling rod lower end end is that two pairs of four incision mixing blade 1 are symmetrical, and blade is certain to direction of rotation inclination
Angle and it is radially fixed there is cutting edge in front end on drilling rod axis, so that drilling rod is smoothly drilled down into and cut the soil body.Blade drilling rod
Shaft different height is provided with mixing blade 2 and cross-cutting blade 3, and rigidity is larger, is unlikely to deform.
Mixing blade 2 is same as incision mixing blade 1, is spaced apart along axial (i.e. length direction) merogenesis of drilling rod, same height
The blade for spending position forms a section, and every section blade is separated by a distance, and each section blade is by one section of screw blade or several blades
Shape blade composition.It is at regular intervals between every layer of mixing blade 2, it can prevent the soil body from continuously up pushing.Cross-cutting blade 3 is fixed on
On the outside of mixing blade, in vertical distribution, parallel with drilling rod axis, there is cutting edge in the advance side of rotation, back laterally moves for drilling rod
The soil body is cut when dynamic rotation.
Larger to spiral blade screw pitch, there is cutting edge in front end, is radially fixed on drilling rod to vane type blade, with level
There is certain inclination angle in face, is inclined to rotation direction, and there is cutting edge in front end, and the spacing between every section blade is larger, prevents spacing is too short will be native
Body is continuously up pushed.
Incision mixing blade width is slightly less than the clear spacing between adjacent drill pipes, in order to avoid collide with adjacent drill pipes.Tightly
There is mouth spray by incision mixing blade upper surface.
When drilling rod rotates, mixing blade carries out stirring up and down to the soil body, increases pile body mixing uniformity.When drilling rod is with pile frame
When transverse shifting, being fixed on the cross-cutting blade on the outside of mixing blade has the function of cutting the soil body, i.e., drilling rod is .ed while rotating
The cross cutting soil body makes entire mixing pile machine have cross cutting agitating function, can carry out to the soil body between rigid stirring pile body
Secondary agitation increases and overlaps thickness between pile body, can also form the cob wall that mixes cement of uniform thickness.
Blade is distributed since the drill bit mouth spray upper end of drilling rod bottom end, up until upper level is compared with stub boring rod bit lower end surface
Until, guarantee shaft blade and upper level compared with not occurring mutually to collide between stub boring rod bit.Radial direction (the i.e. drilling rod diameter of blade
To) width is slightly less than the clear spacing between adjacent drill pipes, in drilling rod rotary course, do not occur mutually to touch between blade and drilling rod
It hits.
Mixing blade and cross-cutting blade are provided in the present embodiment shaft a certain range.Realize the soil layer of different depth by
Different drilling rods are responsible for stirring, greatly reduce the height and self weight of rack, are conducive to the verticality for keeping rack, more main
It is that when drilling rod back moves horizontally, blade drilling rod can be stirred to the soil body and cross cutting, so as to just stirring
Pile body between the soil body or overlap joint weak link be again stirred for, can effectively increase overlap joint overlapping degree between pile body and
The appearance for reducing jag seam between pile body, is greatly improved the continuity and uniformity of cement soil wall.If back moved to two
The soil body between pile body carries out repeating stirring, can form the continuous Soil-cement Wall of uniform thickness.
The drilling rod of the prior art is only provided with vertical incision mixing blade in a bit of range in bottom, and the utility model removes
It is provided with incision mixing blade 1 in drilling rod bottom, mixing blade 2 and cross-cutting blade are provided in the considerably long range of shaft
3, it can not only increase the uniformity of stirring, can also be achieved drilling rod mobile stirring backward, i.e., (whitewashing) is stirred when back moving, right
The lap-joint between stirring pile body just completed carries out encryption stirring, or is again stirred for the soil bodys all between pile body,
The continuity of cement soil wall has been significantly greatly increased in the cement soil wall for forming uniform thickness, reduces the appearance of jag seam between pile body.
It is the preferred embodiment of the utility model it should be noted that described above, the utility model not office
It is limited to above embodiment, as long as its technical effect for reaching the utility model with identical means, it is practical new all should belong to this
The protection scope of type.
