Description
Technical field
The present invention relates to a kind of technical field of civil engineering, especially a kind of filling type stake hollow drill.
Background technology
Current China still use cement pile foundation, or uses multi-turn minor spiral centrum pile, and cement pile foundation is taken a lot of work, time-consuming, expense is expected, unrestrained
Take resource, can not be recycled after construction, pollute environment.Multi-turn minor spiral centrum pile, production difficulty is big, efficiency is low, take a lot of work,
Time-consuming, energy consumption is larger, and it is harder to be screwed into underground during construction, and labour intensity is big, is embedded in underground and easily loosens, built on the sand.
Current bored concrete pile it is the most frequently used have following several forms, the first is early stage mud off construction method, this side
The maximum problem of method can cause a large amount of mud to produce, and the discharge of mud is slowly forbidden straight with individual one big problem, country is transported into
Run in and put mud to river, while the method can cave in hole in punching, serious meeting causes quicksand phenomenon, and casing wall is afterwards
Set, have effect limited.Second method is after present drilling rod drills, concrete directly to be filled, steel after filling concrete
Cage is inserted into concrete with external force afterwards, is occurred The method avoids cement mortar, abbreviation dry filling piles, but this side
It is inaccurate that method can cause steel cage to position, steel cage location curving, and an end of arriving, last pile bearing capacity can be caused during extruding steel cage
And pile quality does not reach design requirement, heavy economic losses is brought to construction party, or even housing quality problem can be caused.3rd
Static pressed pile is planted, soil compaction effect can cause periphery house crack, cause potential safety hazard and the heavy economic losses that cannot be made up.
For problem above, it is badly in need of us and solves.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided phenomenon without squeezing soil during one kind piling, mud is not produced
Slurry, and Jing Yin filling type stake hollow drill.
In order to achieve the above object, a kind of filling type stake hollow drill designed by the present invention, it includes tubular metal
There is through hole body and end cover, the axial direction of tubular metal body, and the internal diameter of through hole is identical with the external diameter of stake；Tubular metal body upper end has
The connection member connected with stake machine, the other end of tubular metal body sets end cover, and end cover and tubular metal body are de-
Unload formula connection；End cover is designed to up big and down small body.
Up big and down small body such as bullet or semicircular body described above etc..
Preferably, connection member be ring flange, and ring flange the one kind being shaped as in circular, square or polygon.
Described dismountable type connection can be threaded connection, make relative separation motion both during reversion, and end cap will have sometimes
Fixed piovt point so that both can perform relative motion, is such as threaded in the outside of end cover, when rotating backward, the sealing
The screw thread that end cap is rotated increases resistance；What described dismountable type connection may also is that, i.e., in the lower end of tubular metal body extremely
A rare interior concave block, the interior concave block a little extends obliquely for tubular metal body lower end, is then extended downwardly into from high point
Another point of tubular metal body lower end, so as to recessed in the range of surrounding, end cover upper end coordinates with tubular metal body lower end, and
The component coordinated with concave block in tubular metal body is upwardly extended, in order that connection is reliable, is further connected by latch at cooperation
Connect, the material manufacture of latch easy fracture, after end cover is subject to concrete pressure, ensure that this is inserted when exiting tubular metal body
Pin fracture；The component makes the lower end outside of tubular metal body in the complete cylinder in surface；Similarly end cover and metal
Tubular body lower end junction component is exchanged and can also realize dismountable type connection.
In order that pouring pile bearing capacity is bigger, described tubular metal body lower end has upwardly extended external screw thread.
The clamping of both end cover and tubular metal body lower end or grafting, clamping or mating force are subject to mixed less than end cover
Solidifying soil pressure, realizes quick separating both when exiting tubular metal body, and clamping or grafting can also be by plastics or plastic cement
Part and other components are realized.
The filling type stake hollow drill it is actually used when it is as follows：The first step, draw hole, borehole cleaning, filling type stake is with hollow
The first soil taking hole forming by the way of dry operation of drilling rod, pore forming process must not produce soil compaction effect；Taken at stake position with pore-forming equipment
Native pore-forming, drilling diameter compares pile body diameterdIt is small, draw hole and be not higher than a bottom designed elevation, and penetration concrete, play borehole cleaning work
With the dregs of taking-up is cleared up in time after fetching earth；Second step：Concrete should be immediately in the position of pore-forming by core drill after pouring into
Bar drill enters, and the drilling rotating speed of sleeve pipe should be matched with subsidence velocity, and sleeve pipe is rotated one week, is accordingly moved down；Described hollow drill
Length is not less than drilled length；Described hollow drill internal orifice dimension is identical with the aperture of pile body；3rd step, placement reinforcing bar
Cage；After hollow drill gets into designed elevation, the good steel reinforcement cage of pre-production is put into drilling rod；4th step, filling concrete；
After steel reinforcement cage is placed, filling concrete is carried out；Start despining during filling concrete and exit hollow drill, irrigated when exiting
Concrete；The speed that tubular metal body is screwed out should be matched with the speed above pulled out, and the speed above pulled out also should be consistent with the speed of rotation,
Sleeve pipe is rotated one week, one pitch of corresponding upper shifting, and curved-line thread path should be consistent with when creeping into, and the process that sleeve pipe gets out should be at the uniform velocity
And it is continuous, so as to form bored concrete pile.
Present invention is designed such that in stake forming process, steel reinforcement cage more accurate positioning, the better quality of stake, while external screw thread
Design make the pile bearing capacity of shaping bigger with the case of using quantity of material identical.
In accordance with the above, a kind of filling type stake hollow drill designed by the present invention, it has simple structure, uses
Convenient and reasonable in design the features such as.
