Description
Technical field
The utility model is related 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 labor 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 problem of method is maximum 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 this 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, directly to fill after concrete, filling concrete steel
Cage is inserted into concrete with external force afterwards, The method avoids cement mortar appearance, abbreviation dry filling piles, but this side
Method can cause the positioning of steel cage inaccurate, 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 can not be made up.
For problem above, it is badly in need of us and solves.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art there is provided phenomenon without squeezing soil during one kind piling, not produced
Raw mud, 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 utility model, it includes metal
There is through hole tubular 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；On tubular metal body
There is the connection member connected with stake machine at end, and the other end of tubular metal body sets end cover, end cover and tubular metal body
Connected for dismountable type；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 is ring flange, and one kind being shaped as in circular, square or polygon of ring flange.
Described dismountable type connection can be threaded connection, make relative separation motion both during reversion, 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 increase resistance that end cap is rotated；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 that 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 by concrete pressure, ensure that this is inserted when exiting tubular metal body
Pin fracture；The component makes outside the lower end of tubular metal body in the cylinder that surface is complete；Similarly end cover and metal
Tubular body lower end junction component, which is exchanged, can also realize that dismountable type is connected.
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 less than end cover by mixed
Solidifying soil pressure, realizes quick separating both when exiting tubular metal body, clamping or grafting can also pass through plastics or plastic cement
Part and other components are realized.
It is as follows during the actual use of the filling type stake hollow drill：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 with pore-forming equipment at stake position
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；Hollow drill is got into after designed elevation, and 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 of the speed above pulled out and rotation also should be consistent,
Sleeve pipe is rotated one week, accordingly moves up a pitch, and curved-line thread path is consistent when should be with creeping into, and the process that sleeve pipe is got out should be at the uniform velocity
And it is continuous, so as to form bored concrete pile.
It is of the present utility model design cause stake forming process in, steel reinforcement cage more accurate positioning, the better quality of stake, while outside
The design of screw thread makes the pile bearing capacity of shaping bigger in the case of with using quantity of material identical.
In accordance with the above, a kind of filling type stake hollow drill designed by the utility model, it have it is simple in construction,
Easy to use and reasonable in design the features such as.
