Abstract
The invention discloses a filling pile spiral hoisting slurry drill pipe, which comprises a section or a plurality of sections of hollow drill pipes and drill pipe joints connected with the hollow drill pipes, wherein spiral blades are arranged on the outer surfaces of the hollow drill pipes; every two sections of hollow drill pipes are connected through the drill pipe joints; and a slurry spraying opening is formed in a connecting part of the first section of hollow drill pipe and a drill bit. Generally, The spiral blades are welded onto a hollow drill hole and are arranged at the lower section of the hollow drill pipes; and the length of the spiral blades is 1/4 to 1/2 of the total length of the hollow drill pipes, and the diameter of the spiral blades is smaller than the diameter of the drill bit. During the construction, the spiral blades rotate in the positive direction along the drill pipes; the upward hoisting force is generated on slurry at the lower section of a pile hole, and mud blocks in the slurry; and meanwhile, downward thrust is generated on the drill pipes. The drill pipe has the effects of connecting the drill bit and transmitting the drill bit and also has the effect of hoisting the slurry, so that the practical value of the drill pipe is improved.
Description
Technical field
The present invention relates to a kind of drilling rod, relate in particular to a kind of castinplace pile screw lifting slurry mud drilling rod.
Background technology
At present, conventional bored pile is in construction pore-creating process, and what drilling rod had act as: the one, and when sinking, drill bit by the connection of many drilling rods, drill bit is connected with construction equipment; The 2nd, rotatory force is delivered to drill bit from construction equipment, make bit.
The patent No.: the Chinese patent that " ZL 20,132 0103907.1 ", patent name are " a kind of soft foundation castinplace pile force cut drill " provides a kind of drill bit, the beneficial effect that uses this drill bit for the drill bit effect of sinking fast, construct high.But this drill bit only limits to for the reverse circulating technique of mud (aspirating mud from drill bit), if construction method adopts mud direct circulation (being to spray mud in drill bit), can cause a concentration of hydraulic mixture for lower end, hole to strengthen gradually, the more difficult aperture of discharging stake from stake hole hypomere of dense slurries and clod.
Summary of the invention
The deficiency existing in order to overcome existing drilling rod, the invention provides a kind of castinplace pile auger stem, it is, on the external surface of the hollow drill of original castinplace pile equipment, helical blade is set, in construction, this helical blade rotates with drilling rod positive direction, the mud of stake hole hypomere and the clod in mud etc. are produced to lifting force upwards, drilling rod is produced to downward propulsive force simultaneously, a slurry that hole hypomere proportion is larger, mud can successfully upwards be discharged from the aperture of stake under lifting force effect.
Technical scheme of the present invention is as follows:
A kind of castinplace pile screw lifting slurry mud drilling rod, comprise one section or some sections of hollow drills and the tool joint being connected with hollow drill, between every section of hollow drill, with tool joint, connect, the junction of first segment hollow drill and drill bit arranges mouth spray, on the external surface of hollow drill, is provided with helical blade.
Preferably, described helical blade is welded on hollow drill.
Preferably, described helical blade is arranged on the hypomere of described hollow drill, the 1/4-1/2 of the total length that the length of described helical blade is described hollow drill.
Preferably, the diameter of described helical blade is less than the diameter of drill bit, is called inside spin technique.
Compared with prior art, beneficial effect of the present invention is as follows:
Castinplace pile auger stem of the present invention is, on the external surface of the hollow drill of original castinplace pile equipment, helical blade is set, in construction, helical blade rotates with drilling rod positive direction, the mud of stake hole hypomere and the clod in mud etc. are produced to lifting force upwards, drilling rod is produced to downward propulsive force simultaneously.This drilling rod not only has the effect that connects drill bit, transmission drill bit, also has the effect that promotes slurry mud.When drilling rod rotates, the lifting force that helical blade makes progress to the formation of sludge in stake hole can successfully upwards be discharged a slurry that hole hypomere proportion is larger, mud under lifting force effect from the aperture of stake, improved the practical value of drilling rod like this.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiments of the present invention are described further:
Fig. 1 is the structural representation of castinplace pile screw lifting slurry mud drilling rod provided by the invention;
Fig. 2 is the fundamental diagram of castinplace pile screw lifting slurry mud drilling rod provided by the invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is explained in more detail.It should be noted that, in these accompanying drawings, all adopt the form of simplifying very much and all use non-ratio accurately, only for convenient, the aid illustration embodiment of the present invention clearly.
Refer to Fig. 1 and Fig. 2, castinplace pile auger stem provided by the invention comprises one section or some sections of hollow drills 2 and the tool joint 1 being connected with hollow drill 2, on the external surface of hollow drill 2, be provided with helical blade 3, between every section of hollow drill 2, by tool joint 1, connect, in first segment hollow drill 2 and the junction of drill bit 5, mouth spray 4 is set.
Wherein, this helical blade 3 is arranged on the hypomere of hollow drill 2, and the length of helical blade 3 is the 1/4-1/2 of the total length of hollow drill 2; The diameter of helical blade 3 is less than the diameter D of drill bit, is called inside spin technique.Helical blade does not need whole bar parcel, and simple in structure, needed driving power is little.
Conventionally, helical blade 3 is welded on hollow drill 2.
In work progress, when hollow drill 2 is rotated in the forward, helical blade 3, with hollow drill 2 positive direction rotations, to generation lifting forces upwards such as the clods 8 in the mud 7 of stake hole hypomere and mud, produces downward propulsive force to hollow drill 2, drill bit 5 simultaneously.This drilling rod not only has the effect that connects drill bit, transmission drill bit, also has the effect that promotes slurry mud.When drilling rod rotates, the lifting force that the formation of sludge in 3 pairs of stake holes of helical blade makes progress can successfully make progress a slurry that hole hypomere proportion is larger, mud and discharges from the aperture 6 of stake under lifting force effect, has improved the practical value of drilling rod like this.
Disclosed herein is only the preferred embodiments of the present invention, and these embodiment are chosen and specifically described to this manual, is in order to explain better principle of the present invention and practical application, is not limitation of the invention.The modifications and variations that any those skilled in the art do within the scope of manual, all should drop in the scope that the present invention protects.
