The eccentric charging structure leads the energy released by explosive explosion to be mainly concentrated at the bottom of the lower edge of the blast hole, thereby causing the problems of extremely irregular profile and the like formed after the explosion of all peripheral holes, reducing the utilization rate of the explosion energy and greatly influencing the explosion effect.
Meanwhile, the existing tunnel blasting explosive loading is carried out on site, the difficulty in controlling the explosive loading process is high due to the site explosive loading, the position of the explosive cartridge cannot be accurately adjusted and controlled, the explosive cartridge cannot be located at an expected position, and the problem of low explosive loading efficiency exists.
Disclosure of Invention
In view of the above, the present invention provides an asymmetric uncoupled fine charging sleeve device, so as to solve the problem of poor smooth blasting quality caused by the fact that a charging structure cannot be accurately controlled due to the adoption of field charging in the existing tunnel smooth blasting, and solve the technical problem of low field charging efficiency.
The asymmetric uncoupled fine explosive charging sleeve device comprises an outer sleeve and an inner sleeve arranged in the outer sleeve, wherein the inner sleeve is used for placing explosives;
the inner sleeve is characterized by further comprising marking grooves formed in the end face of the inner sleeve, two marking grooves are formed in the two end faces of the inner sleeve respectively, a connecting line of the two marking grooves in each end face is intersected with the center line of the inner sleeve, a marking line connected with the marking grooves in the two ends is arranged on the outer surface of the inner sleeve, and the marking line is parallel to the center line of the inner sleeve;
the eccentric adjusting block is fixed on the outer surface of the inner sleeve, and the middle of the eccentric adjusting block is positioned on the marking line.
Furthermore, the outer surface of the inner sleeve is provided with a marking line which is connected with marking grooves at two ends, the marking line is parallel to the central line of the inner sleeve, and the middle part of the eccentric adjusting block is positioned on the marking line.
Furthermore, the eccentric adjusting block is formed by bonding a plurality of layers of gaskets with equal thickness.
The invention has the beneficial effects that:
according to the asymmetrical non-coupling refined explosive-charging sleeve device, the thickness of the eccentric adjusting block can be designed in advance according to the explosive-charging eccentricity, the eccentric adjusting block is fixed on the outer wall of the inner sleeve, and then the inner sleeve filled with explosives is arranged in the outer sleeve, so that the explosive-filled sleeve device can be transported to a blasting site for explosive charging; the marking groove arranged on the end face of the sleeve is aligned with the charging direction mark arranged at the opening of the blast hole during field charging, and the sleeve device can ensure that the explosive is in the designed eccentric position in the blast hole after being inserted into the blast hole, so that the propagation direction of the explosive energy in the peripheral hole can be controlled more accurately. The asymmetrical uncoupled fine explosive-charging sleeve device can realize that the pre-charging of the explosive is completed in a factory, so that the on-site explosive-charging efficiency can be improved; and as the charging eccentricity can be accurately controlled through the inner sleeve, the outer sleeve and the eccentric adjusting block, the fine control of the charging structure is realized, and the propagation direction of the explosive energy of the peripheral holes is accurately controlled, thereby achieving the purposes of improving the utilization rate of the explosive energy and improving the regularity of the profile formed after the peripheral holes are blasted.
