Description
Technical field
This utility model is related to a kind of bi-directional cement soil mixing pile drill bit of ecto-entad whitewashing, belongs to construction machine
Field.
Background technology
Bi-directional cement soil mixing pile drill bit is the vitals of bi-directional cement soil mixing pile machine, and the whether science of its design is closed
Reason directly influences the quality of pile quality.But traditional bi-directional cement soil mixing pile drill bit has following two：One
That mouth spray is typically directly arranged on interior drilling rod wall, during whitewashing, serosity is sprayed from drilling rod to surrounding, with drilling depth and
The increase of jet length, the energy of injection stream are reduced, and the ability for cutting the soil body weakens, cement skewness in the horizontal direction.
If spray pressure is excessive, farther out, fraction slurries are distributed in outside cement mixing method pile body scope serosity jet length, cement
Serosity utilization rate is relatively low；If if spray pressure is too small, serosity jet length is less, and serosity concentrates on cement mixing method stake
Body centre, serosity disappearance outside cement mixing method pile body, therefore along cement mixing method pile body horizontal direction cement point
Cloth is extremely uneven, therefore, cement grout is uneven with soil shear failure.Two are applied in the higher bury of moisture content when mixing pile
In man-hour, soil body adhesion around blade, is easily caused, the ability of cutting soil declines, and is mingled with the soil not stirred in pile body
Block or cement block.Above-mentioned two problems may cause pile quality to decline.
The content of the invention
Goal of the invention：For above-mentioned prior art, there is provided a kind of to can fully ensure that cement with native mixing uniformity by outer
The bi-directional cement soil mixing pile drill bit inwardly whitewashed.
Technical scheme：A kind of bi-directional cement soil mixing pile drill bit of ecto-entad whitewashing, including interior drilling rod and outer drilling rod, it is interior
Drilling rod lower end is connected with apex point, and interior drilling rod is provided with two pairs of lower floor's stirring vanes, and outer drill rod sleeve is located at outside interior drilling rod, outer drilling rod
It is provided with two pairs of upper strata stirring vanes, the direction of rotation of upper strata stirring vane is contrary with the direction of rotation of lower floor's stirring vane.
Further, the reverse side of lower floor's stirring vane and upper strata stirring vane is welded with rake teeth, and rake teeth is by antifriction alloy
Make.
Further, on interior drilling rod, the shotcrete pipe perpendicular to drilling rod, shotcrete pipe are provided with above lower floor's stirring vane
Multiple nozzles are provided with, towards drilling rod, nozzle is about 15 °～45 ° with horizontal plane inclination angle to the opening of nozzle.
Further, lower floor's stirring vane and upper strata stirring vane are made by antifriction alloy steel plate, two pairs of lower floor's paddles
The vertical interval between vertical interval and two pairs of upper strata stirring vane blades between piece is 15～30cm, and blade is located flat
Face is about 10 °～20 ° with horizontal plane inclination angle.
Further, two blades in two blades and upper strata stirring vane in lower floor's stirring vane are in
Decussation is arranged.
Beneficial effect：1st, traditional list mouth whitewashing is changed into into whitewashing of speaking out of turn, whitewashing is changed into ecto-entad from inside to outside by tradition
Whitewashing, can improve serosity utilization rate, improve cement and soil shear failure uniformity, and especially the stirring apart from drilling rod remotely is equal
Even property, greatly improves cement mixing method pile quality.
2nd, alloy rake teeth is set on blade, advantageously reduces the soil body adhesion under the conditions of soft clay, can be with
By the thinner of soil cutting, the soil body caking in pile body is reduced, pile strength is improved.
Description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is overlooking the structure diagram of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is done and is further explained.
As illustrated in fig. 1 and 2, a kind of bi-directional cement soil mixing pile drill bit of ecto-entad whitewashing, including interior drilling rod 1 and outer brill
Bar 2, interior drilling rod lower end are connected with apex point 3, and outer drilling rod 2 is sheathed on outside interior drilling rod 1.Interior drilling rod is provided with two pairs and hands in cross
Lower floor's stirring vane 4 that fork is arranged, setting on outer drilling rod 2 also has two pairs of upper strata stirring vanes 5 arranged in decussation.Lower floor
Stirring vane 4 and upper strata stirring vane 5 are made by antifriction alloy steel plate, the vertical interval between two pairs of lower floor's stirring vanes 4
And the vertical interval between two pairs of 5 blades of upper strata stirring vane is 15～30cm.Every a pair of blades are with regard to drilling rod center
Symmetrically, blade place plane is about 15 °～20 ° with horizontal plane inclination angle.The reverse side of lower floor's stirring vane 4 and upper strata stirring vane 5
Rake teeth 6 is welded with, rake teeth is made by antifriction alloy.On interior drilling rod 1, be provided with above lower floor's stirring vane 4 perpendicular to
The shotcrete pipe 7 of drilling rod, shotcrete pipe 7 are provided with multiple nozzles 8, and towards drilling rod, nozzle is about the opening of nozzle 8 with horizontal plane inclination angle
15 °～45 °.
Blade has interior bull stick and outer bar rotation to drive respectively, and direction of rotation and the lower floor of upper strata stirring vane 5 stir
The direction of rotation for mixing blade 4 should be contrary.With the increase of drilling depth, when construction environment is the higher bury of moisture content,
Upper strata with alloy rake teeth, lower leave are rotated backward, and decline soil cutting in the cutting and direction force effect of rake teeth
It is thinner, the soil body caking in pile body is reduced, cement and soil mixing evenly is realized, so as to reach the work for improving pile strength
With.Near lower floor's stirring vane 4, nozzle 8 is angled towards drilling rod to shotcrete pipe 7 upwards, and cement throwing jet is by 8 export-oriented drilling rod of multiple nozzles
Spray the soil body cut with Jing blades and rake teeth uniformly to mix；And cement throwing jet of the prior art be all from drilling rod laterally
Injection, as the increase of drilling depth and jet length, the energy of injection stream are reduced, cement grout is along cement mixing method stake
Body directional spreding is uneven, and its uniformity mixed with the soil body is significantly less than this device.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
