When it is implemented, interior 1 outer wall of drilling rod is equipped with the first thick tag line 71 and several first thin tag lines 72, the outer brill
2 outer wall of bar is equipped with the second thick tag line 81 and several second thin tag lines 82.Interior drilling rod 1 is rotated according to the scale of tag line, is adjusted
Overlapping area between whole interior slurry discharging hole 51 and outer slurry discharging hole 52, to change grouting pressure.
As shown in Figure 1, its center of the bore of interior slurry discharging hole 51 is all in a vertical straight line, the bore of outer slurry discharging hole 52 its
All in a vertical straight line, ground construction personnel, which rotate interior drilling rod 1, makes the first thick tag line 71 and the second thick tag line at center
81 when being in alignment, and interior slurry discharging hole 51 and outer slurry discharging hole 52 are aligned, and overlapping area is maximum.At this point, in the top slurry discharging hole
Place's insertion rod iron is fixed by interior drilling rod 1 and outer drilling rod 2.It can guarantee the interior slurry discharging hole 51 and outer slurry discharging hole 52 of under ground portion simultaneously
Alignment, to realize orientation grouting and reinforcing.
As shown in Fig. 2, being a kind of state diagram during drilling rod 1 in rotation in figure.Slurries are gushed from two slurry discharging hole intersections
Out, intersection bore is adjustable, and main purpose is to realize that grouting pressure is adjustable, for the soil under different geological conditions
Layer can use different pressure injection slurries, be reinforced, and actual conditions when concrete condition is according to construction select.Inside let out
Slurry hole 51 and the size of 52 overlapping area of outer slurry discharging hole determine by the tag line on the bar wall of inside and outside drilling rod, concrete operation method
For：The state of 2 bar wall high scale line overlap of interior drilling rod 1 and outer drilling rod is observed by drilling rod 1 in rotating, and then determines two slurry discharging holes
Overlapping area.When the second thick tag line 81 on the first thick tag line 71 and 2 wall of outer drilling rod on interior 1 bar wall of drilling rod is overlapped,
Slurry discharging hole and outer slurry discharging hole are completely coincident in indicating, slip casting bore is maximum, grouting pressure is minimum.In addition, interior drilling rod is along outer brill
Bar often turns over a thin tag line, indicates that it rotates 1 ° around outer tube, i.e., inside and outside slurry discharging hole overlapping area reduces, and slip casting bore subtracts
Small, grouting pressure increases.In Specific construction the orientation slip casting under different pressures can be carried out according to requiring to adjust.Adjust overlapping
After area, rod iron of different thickness is inserted into the slurry discharging hole of the top according to overlapping area size, by interior drilling rod 1 and outer drilling rod
2 is fixed.
As shown in figure 3, multi-functional double sleeve slewing drilling machine drilling rods of the utility model further include：It is several to save in lengthening institute
State interior run of steel it is additional in drilling rod and it is several save in the additional outer drilling rod for lengthening the outer run of steel, add in drilling rod
It is identical with the additional joint number of outer drilling rod, and the single-unit length of additional interior drilling rod is greater than the single-unit length of additional outer drilling rod；It is described attached
Add the both ends of interior drilling rod to be designed with inner flange, the lengthening of interior drilling rod is realized by connection inner flange；It is described to add outer drilling rod
Both ends be designed with outward flange disk, pass through the lengthening that connection outward flange disk realizes outer drilling rod；The additional interior drilling rod side is under
Supreme several interior slurry discharging holes of arrangement；The additional outer drill rod sleeve is outside the additional interior drilling rod and additional outer drilling rod side is under
Supreme several outer slurry discharging holes of arrangement；The interior slurry discharging hole and outer slurry discharging hole of drilling rod and additional outer drilling rod corresponding position is big in additional
It is small identical；Two additional drill pipes are hollow tubular and gap at regular intervals is stayed in centre.
When drilling depth is deeper, drilling rod 1 and outer drilling rod in more than 42 spreadings of inner flange 41 and outward flange disk need to be passed through
2.Its sequence of construction is successively the inner flange 41 for first unloading pilot pin 9, then being connected with interior drilling rod 1 and additional interior drilling rod,
The length of drilling rod 1 in extending finally is connected with the outward flange disk 42 of outer drilling rod 2 and additional outer drilling rod, extends outer drilling rod 2
