Description
Technical field
The utility model belongs to technical field of buildings, is related to a kind of drilling rod, more particularly to a kind of for making mixing pile
Telescopic drill rod.
Background technology
At present, the piling machinery for being used on construction site has two kinds：A kind of swivelling pile driver, the structure of this piling machine
It is, using the drilling rod hanger bracket of hoist engine pull-up, to drive rod bit to be set to the piling of drifter drill for underground pore-forming by by unit head
It is standby；Another kind is jump bit piling machine, and the structure of this piling machine is fallen repeatedly using hoist engine pull-up jump bit, and lifting comes
Realize piling.Wherein, swivelling pile driver mainly realizes the purpose to underground drilling rod in piling by circumferentially rotating for drilling rod,
Drilling rod is lowered the temperature and cementing operations are carried out to drilling rod using grouting while drilling rod drills, common grouting is main
Whitewashed by the grout hole of drill rod end, when drilling rod gets into certain depth, it is necessary to drilling rod supernumerary segment, extend drilling rod,
Drill down could be continued, it is necessary to shutdown operation, whitewashes in stopping process and also stop during supernumerary segment, gunniting hole easily block and
Influence job schedule.
In order to solve the problems, such as prior art, people have carried out long-term exploration, it is proposed that solution miscellaneous
Scheme.For example, Chinese patent literature discloses a kind of bored concrete pile screw lifting slurry-mud drilling rod [application number：
201410263015.7], it includes one section or some sections of hollow drills and coupled tool joint, outside hollow drill
It is provided with surface between helical blade, every section of hollow drill of every section of hollow drill and is connected with tool joint, first segment hollow drill
Junction with drill bit sets mouth spray.Generally, the helical blade is welded on core drilling, and is arranged under hollow drill
Section, the length of helical blade is the 1/4-1/2 of the total length of hollow drill, diameter of its diameter less than drill bit.The spiral shell in construction
Vane piece is rotated with drilling rod positive direction, and upward lifting force is produced to clod in the mud and mud of stake holes hypomere etc., while
Downward propulsive force is produced to drilling rod.Such scheme solves asking for existing drill pipe for pile driver grouting effect difference to a certain extent
Topic, but the program is still existed：Needing shutdown could realize extension arm.
The patent drill pipe for pile driver component [application number applied before the applicant：201610068750.1], it is including hollow
Drilling rod body, drilling rod body one end has drill bit tapering, and one end outer circumferential for being provided with drill bit tapering in drilling rod body is provided with and is in
The augers blade that spiral distribution is set, augers blade one end extends to drill bit tapering, and the other end sets with radial direction
Put the whitewashing seat in the external side of drilling rod to be connected, whitewashing seat has at least one with portion in drilling rod body towards the side in drill bit tapering
Connected gunniting hole, and the aperture of gunniting hole becomes larger from inside to outside.Advantage is：It is not susceptible to block existing during whitewashing
As, and there is whitewashing area greatly, and slurries can be made to be sprayed in fan-shaped, gunite effect is good, and good stability when drilling rod is circumferentially rotated is difficult
There is dancing, improve the efficiency of drilling rod drilling, be difficult to interfere between drilling rod.But program a fly in the ointment
