Description
Technical field
The present invention relates to smooth Surface Blasting Technology field, in particular to a kind of photoface exploision fining means for loading.
Background technique
In the Smooth Blasting Construction of tunnel scene, decoupling charge structure is generallyd use, because of powder stick in decoupling charge structure
There are gap between blasthole, powder stick is usually to contact with hole wall on the downside of blasthole, therefore form bias not under the effect of gravity
Coupling charging structure.The energy that this bias charge constitution causes explosive charge to be discharged is concentrated mainly on blasthole lower edge bottom,
The problems such as profile formed after each periphery hole explosion is extremely irregular is in turn resulted in, reduces the utilization rate of explosion energy, greatly
Affect demolition effect.
Simultaneously because existing Tunnel Blasting powder charge is all to carry out at the scene, live powder charge causes powder charge process to control difficulty
Greatly, it can not accurately adjust, control powder stick position, powder stick cannot be made to be in desired position, and that there is also loading rates is low
Problem.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of asymmetric do not couple to refine charge sleeve device, to solve
In existing tunnel photoface exploision, using live powder charge, being unable to accurately control charge constitution leads to the ropy problem of photoface exploision,
And solve the low technical problem of live loading rate.
The present invention is asymmetric not to couple fining charge sleeve device, including outer tube and the inner sleeve being arranged in outer tube
It manages, explosive is used in the inner sleeve；
Further include the labeled slots being arranged in interior box face, is respectively arranged at two and marks in the both ends of the surface of inner sleeve
Slot, and the line of labeled slots intersects with the center line of inner sleeve at two on each end face, sets on the outer surface of the inner sleeve
It is equipped with the mark line of connection both ends labeled slots, the centerline parallel of the mark line and inner sleeve；
It further include the eccentric adjusting block being arranged between outer tube and inner sleeve, the eccentric adjusting block is fixed on inner sleeve
On outer surface, and the middle part of eccentric adjusting block is located on mark line.
Further, be provided on the outer surface of the inner sleeve connection both ends labeled slots mark line, the mark line with
The middle part of the centerline parallel of inner sleeve, the eccentric adjusting block is located on mark line.
Further, the eccentric adjusting block is made of the gasket bonding of several layers equal thickness.
Beneficial effects of the present invention:
The present invention is asymmetric not to couple fining charge sleeve device, can be according to the pre-designed eccentric tune of powder charge eccentricity
The thickness of locking nub, and eccentric adjusting block is fixed in inner sleeve pipe outer wall, the inner sleeve for installing explosive is then packed into outer tube
In, the casing bit for installing explosive can transported to demolition site powder charge in this way；It will be arranged when live powder charge in box face
On labeled slots with the powder charge azimuth mark of blasthole oral area is set to just, can guarantee that explosive exists after casing bit insertion blasthole
Eccentric position in design in blasthole, so as to more accurately control the direction of propagation of periphery hole explosive energy.The present invention is non-
Symmetrically do not couple fining charge sleeve device, may be implemented factory complete explosive it is prefilled, so that live powder charge can be improved
Efficiency；And due to accurately controlling powder charge eccentricity by inside and outside casing and eccentric adjusting block, realize charge constitution fining
Control, accurately controls the direction of propagation of periphery hole explosive energy, improves explosion energy utilization rate to reach and improves week
The purpose of formed profile regularity after lateral opening explosion.
Detailed description of the invention
Fig. 1 is the asymmetric end structure illustration for not coupling fining charge sleeve device of the present invention；
Fig. 2 is arragement construction schematic diagram of the eccentric adjusting block on interior sleeve surface.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As shown, the present embodiment is asymmetric not to couple fining charge sleeve device, including outer tube 1 and setting are outside
Inner sleeve 2 in casing is used for explosive in the inner sleeve.
The asymmetric fining charge sleeve device that do not couple of the present embodiment further includes the label being arranged in interior box face
Slot 3 is respectively arranged with labeled slots at two in the both ends of the surface of inner sleeve, and at two on each end face labeled slots line and inner sleeve
The center line of pipe intersects, and is provided with the mark line 4 of connection both ends labeled slots on the outer surface of the inner sleeve, the mark line with
The centerline parallel of inner sleeve.
The asymmetric fining charge sleeve device that do not couple of the present embodiment further includes being arranged between outer tube and inner sleeve
Eccentric adjusting block 5, the eccentric adjusting block is fixed on inner sleeve tube outer surface, and the middle part of eccentric adjusting block is located at mark line
On.
Using in the present embodiment it is asymmetric do not couple fining charge sleeve device carry out filling explosive process it is as follows:
1) two pieces of eccentric adjusting blocks are first designed according to powder charge eccentricity；
2) by eccentric adjusting block along the outer surface that mark line is fixedly bonded to inner sleeve；
3) explosive is fitted into inner sleeve；
4) inner sleeve is fitted into outer tube；
5) casing bit equipped with explosive is transported to demolition site, and carries out live powder charge: will be arranged in box face
Labeled slots (the powder charge azimuth mark of blasthole oral area is designed according to explosion to positive with the powder charge azimuth mark of blasthole oral area is arranged in
It is engraved on blasthole oral area in advance), casing bit is then inserted into blasthole, the outer diameter of outer tube and the diameter of blasthole are suitable, so that
Fit clearance is in scope of design after it is packed into blasthole.
It is asymmetric through this embodiment not couple fining charge sleeve device, it may be implemented to complete explosive prepackage in factory
It fills out, so that live loading rate can be improved；And due to accurately controlling powder charge bias by inside and outside casing and eccentric adjusting block
Away from realization charge constitution Precise control guarantees that position of the explosive in blasthole is on the eccentric position of design, to reach
It improves explosion energy utilization rate and improves the purpose of formed profile regularity after periphery hole explosion.
The eccentric adjusting block is made of the gasket bonding of several layers equal thickness as a further modification of the present embodiment,；In this way
The thickness of eccentric adjusting block can be adjusted by changing the number of plies of gasket, in this way can be easily by the thickness tune of eccentric adjusting block
The whole thickness to needs.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
