Description
Technical field
The utility model belongs to ground-connecting-wall construction field, more particularly to tiltedly rock groove section trenching construction.
Background technology
In ground-connecting-wall construction, when ground-connecting-wall groove section meets rock structure, chute forming machine can not complete grooving operation, it is necessary to using punching
Hit and be drilled into grooving operation, universal chopping bit is generally plum blossom type end side and bores hammer.In the case of complex geologic conditions,
Rock face absolute altitude changes greatly in groove, and end face unbalance stress easily produces sideslip during plum blossom type end side bores hammering blow.
Bore hammer in impact process produce sideslip the main reason for be oblique rock surface in groove, bore hammer punching to end face during bottom land by
Power is uneven and causes hammer body to the smaller side slip of stress, and as impact operation is carried out, gradually increase of breakking away causes rock in groove
Face protrudes side owe punching and weak soil side then overshoot, influences grooving size and perpendicularity.
Have for generally use treating method in the case of there is oblique rock in ground-connecting-wall construction groove section：
1. backfill slabstone in groove to impact again, the method cost increase claim for eot, and after backfill slabstone, rock side
Still above weak soil side on strength performance, can only partly solve the phenomenon of end face unbalance stress, block stamp still breaks away,
The grooving quality that wastes time and energy still can not ensure；
It is oriented to 2. applying row's towing pad in groove section and being bored for auxiliary impact, cost, claim for eot will be significantly greatly increased.
Utility model content
The purpose of this utility model is：A kind of oblique rock groove section rectangular impact drill bit of ground-connecting-wall construction is proposed, is adapted to punching
The brill that oblique rock be present is hit in groove to hammer into shape to ensure grooving size and perpendicularity.
The utility model purpose is realized by following technical proposals：
A kind of oblique rock groove section rectangular impact drill bit of ground-connecting-wall construction, including blossom type impact drill, in addition to side plate, circular cone
Body hammer tooth, hammer plate, side plate are the flat board that a side is toothed edge, and four blocks of side plates are around the brill hammering blow face of blossom type impact drill
Side and surround rectangle, each side plate base is toothed edge, and each base is concordant and the plane and the brill of blossom type impact drill that are formed
Hammering blow face is concordant, and the brill hammering blow face of blossom type impact drill is using the straight line of certain parallel side plate as cut-off rule, by shock surface point
For two parts, some cones hammer teeth are arranged on a part of shock surface, the fixed hammer plate of covering on another part shock surface, hammer plate is
One flat board, its plane is concordant with the plane that each side plate base is formed, and cone hammer tooth is higher by hammer plate plane.
Alternatively, arrange that cone hammer tooth and covering fix the brill hammering blow of hammer plate in face of partly dividing equally.
Alternatively, the toothed edge of side plate is rectangular saw-tooth, and rectangular saw-tooth is continuous for interval 50mm 50mm*50mm breach
Form.
Alternatively, cone hammer tooth is uniformly distributed on the brill hammering blow face of blossom type impact drill, cone hammer tooth bottom
Face diameter 50mm, the high 50mm of cone, cone hammer tooth are higher by hammer plate plane 20mm.
The foregoing main scheme of the utility model and its each further selection scheme can be with independent assortments to form multiple schemes,
The scheme that can be used and be claimed for the utility model；And the utility model, (each non conflicting selection) selection between and and
Can also independent assortment between other selections.Those skilled in the art after the utility model is understood according to prior art and
Common knowledge, which can understand, multiple combinations, is the claimed technical scheme of the utility model, does not do exhaustion herein.
The course of work is：Rock projection side in side corresponding groove section with cone hammer tooth, hammer into shape soft in plate corresponding groove section
Native side, carry out jet-bedding operation.Hammer crest face is higher than steel plate surface, impacts to bottom land hour hammer tooth and takes the lead in contacting with rock face, utilizes
The stress concentration effect for hammering crest end into shape produces destruction to rock, and steel plate surface when to be plane contact with bottom land soil layer stress it is more equal
It is even, it is smaller to land destruction power.The uneven influence of hammer tip face impulsive force is bored to offset with the difference of end face stress surface structure type.
Especially, incorporation engineering construction is actual in the present invention, and solid drill is designed as rectangular shape, for ease of ground-connecting-wall square
Shape groove section is constructed.Further, rectangular steel plates have also further played following effect：
(1) prevent hammer from causing half of drill hammer end face with cone to deviate the scar position to be impacted in groove internal rotation.
(2) dissection is produced to the shock surface surrounding soil body, ensures that shock surface surrounding soil is not damaged as far as possible, so as to
Ensure the perpendicularity of jet-bedding and the stability of the cell wall soil body.
And the sawtooth on steel plate then further has following special role：
(1) the addi-tional crusher soil body.
(2) space of slagging tap is provided to have rushed broken dregs, by sawtooth space, is easy to disintegrating slag to be extruded from flat side of a hammer side, with
Mud emission, improve scarfing cinder efficiency
(3) hammer tip face and bottom land soil body adhesive force are bored in increase, prevent hammer body from rotating and sliding.
In addition, cone hammer tooth is higher by hammer plate plane 20mm, it is easy to drill bit hammer tooth side to shift to an earlier date the rock at contact groove bottom, concentrates
Overall tup stress, increase impact dynamics.
The beneficial effects of the utility model：The utility model passes through the simple and easy ingenious solution realistic problem of mode：It is logical
Crossing change brill brill hammer tip face structure type makes it have different contacts area from bottom land Rock projection side and weak soil side, so as to support
The ground character difference that disappears produces the difference of recoil strength to hammer body, effectively solves the problems, such as the oblique rock groove section trenching construction of ground-connecting-wall construction.
Meanwhile the quincunx brill used in the utility model is hammered into shape, hammer plate, hammer tooth are easily purchased easily, dosage is few, and processing gets up to be convenient to,
Can process at the construction field (site), and punching groove section need not do any treatment measures can implement jet-bedding operation, both efficiently and
Economy, overcome the major defect of the high cost long duration of prior art other method.
