Embodiment
The embodiment of the present invention has been described in detail in the content of the invention, is not repeated herein, need to be described as follows：
One, is referring to Fig. 1, Fig. 2, and generally, the concrete-pile 12 after blocking need to retain the stake cage bar 13 of 500 millimeters length not
Cut-out, this section of reinforcing bar need to be embedded in the pile framing subsequently poured, therefore blocking stake needs two steps to carry out, and first have to peel off concrete
Protective layer (concrete beyond stake cage bar), stake cage bar 13 is exposed, then from cutting at stake plane 14 by top stake core coagulation
Soil excision, 3 hydraulic shears of design seek to reach the purpose for peeling off concrete cover the present invention up and down, and concrete cover is only
There are 50 millimeters thicks, the power that hydraulic system 2 applies need not be very big, therefore hydraulic shear B11 is not required to design hydraulic system, by upper and lower
Two hydraulic shears drive can；The protruded length of top pricker 4 is substantially identical with thickness of concrete cover, pushes up the top elder generation of pricker 4
Insert in concrete, will by the pricker body that gradually expands by longitudinal attrition crushing of the brittle concrete cover along stake cage bar 13
Concrete cover is peeled off, and cuts concrete cover of the stake plane below 14 due to the effect of contraction by bottom concrete, no
It can be destroyed；Need to illustrate：Now the cutting ring 3 of 3 hydraulic shears does not all touch the outer wall of concrete-pile 12, i.e., the ring of 3 hydraulic shears
Knife 3 is not all started working.Two, need not when the inner concrete of section stake plane more than 14 is cut off referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4
Upper hydraulic shear A1 and hydraulic shear B11 work, only need to descend hydraulic shear C21 to complete, and after concrete cover is peeled off, continue jacking
Lower hydraulic shear C21, lower hydraulic shear C21 top pricker 4 continue in jacking inner concrete, and same hydraulic shear C21 at present cutting ring 3 is therewith
Jacking is started working, and the rough concrete cover cut at stake plane 14 is cut off, due to cutting stake plane below 14
Inner concrete is constrained by the stake cage bar 13 at this and pile concrete, when top pricker 4 continues jacking inner concrete, cuts stake
The inner concrete of plane more than 14 can be forced up displacement, and the concrete up and down cut at stake plane 14 is fitly separated, this
When stake cage bar 13 be not subjected to displacement, only less elastic deformation, inner concrete will with stake cage bar 13 is differential separates, now ring
Knife 3 does not touch a cage bar 13, and the stake cage bar 13 cut at stake plane 14 is not affected by injury, and this is also exactly that the present invention section stake plane is whole
Together, not the advantages of not damaging reinforcing bar；Need to illustrate：Lower hydraulic shear C21 blocks inner concrete from a direction can.Three, join
See Fig. 5, Fig. 6, upper hydraulic shear A1, hydraulic shear B11 and lower hydraulic shear C21 vertical position can adjust, can be according to different
Cut stake situation and carry out position adjustment.Four, are referring to Fig. 2, and lower hydraulic shear C21 working frequency is high, if the top grade of pricker 4 primary structural component damage
It is bad, three hydraulic shears can be changed to direction up and down and used, can so reduce maintenance frequency；To consider liquid when designing hydraulic shear
The ability to work of pressure system, while to consider cutting ring 3 and push up the hardness of pricker 4.
