Abstract
The utility model relates to a drill bit for a device for foundation treatment, in particular to a drill bit blade used for a deep cement-soil mixing pile. A main body of the drill bit blade adopts a double-layer hollow structure with a V-shaped transverse section, the hollow part serves as a slurry spray pipeline, a slurry spray hole is formed in the middle on the inner side of the intersected tip part of the double layers, and a slurry flow groove is formed on the intersected inner side surface of the double layers. The utility model modifies the traditional single-layer blade into a double-layer blade with a double-layer hollow structure, thereby solving the problems that slurry cannot be sprayed from the slurry spray position required for the designed pile top in the traditional single-layer blade, but is sprayed form the ground to lead to cement slurry existing in the hollow pile part where cement slurry is not allowed to exist, waste of material as well as increased excavation difficulty of the hollow pile part.
Description
Technical field
The utility model relates to the equipment drill bit that ground is handled usefulness, specifically a kind of cement soil deep agitation pile bit blades.
Background technology
Existing cement soil deep agitation pile bit blades is the individual layer blade, its gunniting hole position is generally below blade, before the construction, all need to check earlier with steel wire whether a gunniting hole exists stifled slurry phenomenon, after seeing that slurries flow out, just begin to turn round the whitewashing pile, occur the injected hole phenomenon occurring stopping up in the drill bit insertion soil, cause useless stake to avoid not checking.Just there is a problem in this: whitewashing can not require the whitewashing position to begin whitewashing from design stake top, but must begin whitewashing on ground, cause the position of empty the cement paste that partly do not have also to have cement paste, not only cause the waste of material, also increased the difficulty of empty stake part excavation.
Summary of the invention
Goal of the invention of the present utility model is to cause the wasting of resources, empty stake part to excavate the bigger deficiency of difficulty at prior art, provide a kind of can be from the designing requirement cement soil deep agitation pile bit blades that the position begins to whitewash of whitewashing.
Realize the foregoing invention purpose by the following technical solutions: a kind of cement soil deep agitation pile bit blades, comprise blade body, described blade body is that the cross section is＜the double-deck hollow structure of shape, and inboard centre position, two-layer crossing tip is provided with mouth spray.
Compared with prior art, the utility model changes traditional individual layer blade the twi-tier blade of double-deck hollow structure into, having solved to cause the waste of material and empty stake part to excavate the problem that difficulty strengthens in the ground whitewashing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model and drilling rod connection diagram.
Among the figure: blade 1, mouth spray 2, slurries chute 3, drilling rod 4.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1, cement soil deep agitation pile bit blades described in the utility model, the body of its blade 1 is that the cross section is＜the double-deck hollow structure of shape, cavity is as the whitewashing pipeline, inboard centre position, two-layer crossing tip has mouth spray 3, and two-layer crossing medial surface forms slurries chute 3.
Referring to Fig. 2, blade 1 one ends are connected with drilling rod 4, and drilling rod 4 tube chambers are communicated with the cavity of blade 1, and slurries enter the whitewashing pipeline that is made of blade 1 cavity from drilling rod 4 tube chambers, again by mouth spray 2 ejections, and spray under the effect of slurries chute 3.By drill bit direction of rotation among the figure as can be known, slurries spray against the drill bit direction of rotation.
Claims (1)
1. a cement soil deep agitation pile bit blades comprises blade body, it is characterized in that, described blade body is that the cross section is＜the double-deck hollow structure of shape, and inboard centre position, two-layer crossing tip is provided with mouth spray.
