Abstract

The invention discloses a non-symmetric non-coupling refined charging sleeve device which comprises an outer sleeve, an inner sleeve arranged in the outer sleeve, marking grooves arranged on the end surfaces of the inner sleeve respectively and eccentric adjusting blocks arranged between the outer sleeve and the inner sleeve; each of the two end surfaces of the inner sleeve is provided with two marking grooves; a connecting line of the two marking grooves on each end surface is intersected with a center line of the inner sleeve; the outer surface of the inner sleeve is provided with marking lines for connecting the marking grooves at the two ends; the eccentric adjusting blocks are fixed on the outer surface of the inner sleeve; and the middle parts of the eccentric adjusting blocks are arranged on the corresponding marking lines respectively. By adopting the non-symmetric non-coupling refined charging sleeve device, explosive prefilling can be completed in a factory, so that the fieldcharging efficiency can be improved; and in addition, as a charging eccentric distance can be accurately controlled by the inner sleeve, the outer sleeve and the eccentric adjusting blocks, refined control of a charging structure is realized, the utilization rate of an explosive energy is increased, the purpose of improving the regularity of a contour formed after the peripheral holes are exploded is achieved.

Description

technical field [0001] The invention relates to the technical field of smooth blasting, in particular to a refined charge device for smooth blasting. Background technique [0002] In the smooth blasting construction of the tunnel site, the uncoupled charge structure is usually adopted. Because there is a gap between the charge roll and the blast hole in the uncoupled charge structure, the charge roll is generally in contact with the lower side wall of the blast hole under the action of gravity, so An eccentric uncoupled charge structure is formed. This eccentric charge structure causes the energy released by the explosive explosion to be mainly concentrated at the bottom of the lower edge of the blast hole, which in turn causes problems such as extremely irregular contours formed after the blasting of each peripheral hole, which reduces the utilization rate of the explosion energy and greatly affects the Blast effect. [0003] At the same time, because the current tunnel b...
