Description
Technical field
The invention belongs to piling Technology field, especially relate to a kind of pile cover former and Stake head handling is executed with pile cover
Work method.
Background technology
Nowadays, after bored pile piling, generally using manual type to carry out pile cover construction, pile cover is generally concrete knot
Structure.If Fig. 1-1 is to shown in Fig. 1-8, when using manual type to carry out pile cover construction, work progress mainly comprises the steps that the
After one step, boring 1-1 molding, drilling rod 1-2 limit is upwards carried limit and passes through drilling rod 1-2 concrete perfusion in boring 1-1, refer to figure
1-1；Second step, drilling rod 1-2 is upwards carried to boring 1-1 outside, and in hole to be drilled 1 institute's concrete perfusion solidification after, it is thus achieved that fill
Note stake pile body 1-3, for ensureing pile crown quality, the elevation of top of bored concrete pile pile body 1-3 typically will exceed the stake top being pre-designed
Absolute altitude, the most above ground level, refer to Fig. 1-2；Outside 3rd step, the sections basseting bored concrete pile pile body 1-3, dregs is carried out
Cleaning, refers to Fig. 1-3；The diameter D and height h of the concrete pile follower 1-5 that the 4th step, basis are pre-designed, manually at pile crown
Dig out the cylindric clay model 1-4 for the concrete pile follower 1-5 that constructs, the diameter of cylindric clay model 1-4 and the most respectively with in advance
The diameter D of the concrete pile follower 1-5 of design is identical with height h, refers to Fig. 1-4；4th step, artificial by bored concrete pile pile body 1-3's
Pile crown is cut to concordant with ground, refers to Fig. 1-5；6th step, manually it is truncated to be pre-designed by the pile crown of bored concrete pile pile body 1-3
Stake top mark high, it is thus achieved that the pile body 1-6 of construction molding, refer to Fig. 1-6；7th step, in cylindric clay model 1-4 irrigate coagulation
Soil, refers to Fig. 1-7；8th step, until in cylindric clay model 1-4 institute's concrete perfusion solidification after, it is thus achieved that the concrete of construction molding
Pile cover 1-5, refers to Fig. 1-8.
It addition, in above-mentioned second step after filling concrete, do not carry out Stake head handling immediately, but after waiting 28 days, institute

Inside complete to process；Meanwhile, after the pile concrete pouring construction of constructed bored concrete pile completes 28 days, institute's concrete perfusion is complete
Solidification, just can carry out pile cover construction；The second, low cost: Fully-mechanized operation, without extra labour cost, integration pile cover shapes
Device energy simplicity is contained on a machine and works, it is not necessary to other autonomous device；3rd, by stake holes aperture is cleared up, can be effective
Improve inter-pile soil cleaning efficiency, while cleaning stake holes aperture, complete because pile crown is processed, do not basset, therefore excavate
Without avoiding pile crown during operation, working performance is high；4th, work progress does not affect pile quality, will stake when pile crown does not solidifies
Head has processed, and subsequent job will not impact wreckage pile crown；5th, construction quality is controlled: height and the diameter of pile cover take
Certainly in size and the setting of parameter in drilling process, few man's activity, the steady quality of drill bit；6th, pile cover former is used
Carry out pile cover clay model construction, it is possible to effectively extrusion soil, make hole wall closely knit, improve the stressed effect of pile cover.
In sum, the present invention is reasonable in design, easy construction and using effect good, can easy, be rapidly completed pile cover construction
Process, work progress is easily controllable, and the pile cover quality of construction molding is high.
Below by drawings and Examples, technical scheme is described in further detail.
