Detailed description of the invention
Summary of the invention has been described in detail the detailed description of the invention of the present invention, is not repeated herein, and need to be described as follows:
One. seeing Fig. 1, Fig. 2, generally, the concrete-pile 12 after blocking need to retain the main muscle of stake 13 of 500 millimeter length not
Cutting off, this section of reinforcing bar need to be embedded in the follow-up pile framing poured, and therefore blocking stake needs two steps to carry out, and first has to peel off concrete
Protective layer (concrete beyond the main muscle of stake), comes out main for stake muscle 13, then from cutting top stake core coagulation at stake plane 14
Soil excision, the present invention designs the purpose that 3 hydraulic shears seek to reach to peel off concrete cover up and down, and concrete cover is only
Having 50 millimeters thick, the power that hydraulic system 2 applies need not very big, and therefore hydraulic shear B11 is not required to design hydraulic system, by upper and lower two
Individual hydraulic shear A1 drives the most permissible；The protruded length of top pricker 4 is the most identical with thickness of concrete cover, the top elder generation of top pricker 4
In insertion concrete, by the pricker body gradually expanded by the concrete cover of fragility along longitudinal attrition crushing of the main muscle of stake 13, incite somebody to action
Concrete cover is peeled off, and the concrete cover of section stake plane less than 14 is due to the effect of contraction by bottom concrete, no
Can be destroyed；Need explanation: now the cutting ring 3 of 3 hydraulic shears does not all touch the outer wall of concrete-pile 12, the i.e. ring of 3 hydraulic shears
Cutter 3 is not all started working.Two. see Fig. 1, Fig. 2, Fig. 3, Fig. 4, need not when cutting the inner concrete excision of stake plane more than 14
Upper hydraulic shear A1 and hydraulic shear B11 work, only need to descend hydraulic shear A1 to complete, and after concrete cover is peeled off, continues jacking
The top pricker 4 of hydraulic shear A1, hydraulic shear A1 continues in jacking inner concrete, and cutting ring 3 jacking therewith of hydraulic shear A1 simultaneously starts
Work, will cut the rough concrete cover excision at stake plane 14, owing to cutting the stake core coagulation of stake plane less than 14
Soil is retrained by the main muscle of the stake at this 13 and pile concrete, when top pricker 4 continues jacking inner concrete, cut stake plane 14 with
On inner concrete can be forced up displacement, fitly separate cutting the concrete up and down at stake plane 14, the main muscle of now stake
13 are not subjected to displacement, the least elastic deformation, and inner concrete separates differential for muscle 13 main with stake, and now cutting ring 3 does not touches
And the main muscle of stake 13, cut the main muscle of stake 13 at stake plane 14 and be not affected by injury, this most just the present invention to cut a plane neat, do not damage
The advantage of reinforcing bar；Need explanation: inner concrete just can be blocked by lower hydraulic shear A1 from a direction.Three. see Fig. 5, Fig. 6,
The vertical position of upper hydraulic shear A1, hydraulic shear B11 and lower hydraulic shear A1 can adjust, and can carry out according to different stake situations of cutting
Position adjustment.Four. the operating frequency seeing Fig. 2, lower hydraulic shear A1 is high, if top pricker 4 primary structural component such as grade damages, can be by three liquid
Pressure is cut and is changed direction use up and down, so can reduce maintenance frequency；The work energy of hydraulic system to be considered when designing hydraulic shear
Power, cutting ring 3 to be considered and the hardness of top pricker 4.Four. see Fig. 1, the cutting ring 3 of annular knife rest 10 and cutting ring 3 are fixed with many
Individual top pricker 4, the direction of its overall dimensions and multiple tops pricker 4 is all designed, referring back to Figure 14 and figure by the stake shearing 800 mm dias
15, when hydraulic shear shears the stake of 600 mm dias, multiple tops pricker 4 position relative with stake with shear 800 mm dias stake time
Multiple tops pricker 4 is similar with the relative location comparison of stake, and when simply shearing the stake of 600 mm dias, part top pricker 4 is relative with stake
Position is slightly offset, and substantially without affecting shear effect, therefore the present invention can be suitable for simultaneously shear 800 mm dias
Stake and the stake of 600 mm dias, and simple structure is practical；The present invention is patent of invention " a kind of amputation coagulation that I has applied for
The hydraulic shear of soil pile crown " application number: the modified model of 2016108971741.
