Abstract
The invention discloses a blasting charge structure. The blasting charge structure comprises a PVC pipe (1). An upper pipe body and a lower pipe body of the PVC pipe (1) are provided with two symmetrical cutting grooves (2) which are not communicated with each other. The problems that in an existing technology, the pre-splitting blasting charge technology is original and outdated, the field fabrication is manpower and finical resource wasted, and the working efficiency is low. In the charge process, a powder charge is difficult to meet the pre-splitting blasting charge requirement for non-coupling mediate, and is in direct contact with the cannon hole wall, the pre-splitting face is severely damaged by the generated high-pressure impact wave, and the problems that the damage occurs on the reserved working face, and the design effect of pre-splitting blasting cannot be achieved are caused.
Description
Technical field
The invention belongs to blasting technique, particularly relate to a kind of blast charging structure.
Background technology
Presplit blasting is special controlled blasting, namely a relatively intensive big gun hole of row is arranged along design profile face, and detonating prior to the big gun hole in excavation area, first the through precracking that one has one fixed width is formed, precracking can play the effect of the rock mass being separated excavation area and reserved area, thus reduce greatly the vibrations and destruction that country rock is subject to when detonating in Nei Bao hole, excavation area, keep the primary stability of rock medium as far as possible, and leave the sliding excavation face of half comparatively complete hole wall peace lay the grain.Can presplit blasting the key of extensive use be rationally determine charge constitution aborning.For realizing design effect, often adopt Uncoincided charge or low dose of powder charge.But at present, domestic presplit blasting, photoface exploision and buffer shooting mainly adopt small diameter medicine roll and primacord to be banded in loading method on bamboo chip, the linear charging density of design is realized by changing powder stick spacing, the original backwardness of charge process, field fabrication labor intensive financial resources, operating efficiency is low.In powder charge process, to be often difficult to realize not being coupled of presplit blasting powder charge requirement placed in the middle for cartridge bag, and directly contact with big gun hole wall, the high-pressure shocking wave produced makes pre-broken face heavy damage, may cause the destruction of reserved working face, cannot realize the design effect of presplit blasting.
Summary of the invention
The technical problem to be solved in the present invention: provide a kind of blast charging structure, to solve the original backwardness of prior art presplit blasting charge process, field fabrication labor intensive financial resources, operating efficiency is low.In powder charge process, to be often difficult to realize not being coupled of presplit blasting powder charge requirement placed in the middle for cartridge bag, and directly contact with big gun hole wall, the high-pressure shocking wave produced makes pre-broken face heavy damage, may cause the destruction of reserved working face, cannot realize the problems such as the design effect of presplit blasting.
Technical solution of the present invention:
A kind of blast charging structure, it comprises pvc pipe, lower tube body offers pvc pipe respectively two disconnected groovings of symmetry.
The width of grooving is the 15-25% of pvc pipe diameter.
The body of pvc pipe and grooving junction offers fixed card slot, and fixed card slot internal fixtion has fan-shaped center configuration.
Size and the big gun hole dimension of fan-shaped center configuration agree with.
Beneficial effect of the present invention:
The present invention lower tube body offers respectively two disconnected groovings of symmetry on pvc pipe, and adjacent holes line forms troughs for collecting energy, forms similar clip structure, be convenient to laying of cartridge bag under the prerequisite ensureing energy-gathering jetting, and easy controlled loading of explosive interval, cumulative shooting flow can be produced in the grooving direction of body, the high-pressure spray formed along grooving direction in blast process produces slabbing action to hole wall medium, contribute to formation smooth, smooth reserved face, improve surrounding rock stability, the present invention adopts and offer fixed card slot on pvc pipe body, fixed card slot internal fixtion has fan-shaped center configuration, fan-shaped center configuration does not slide after being placed into draw-in groove under vertical effect mutually to utilize the structure of fan-shaped center configuration outer fan to guarantee, do not offset, guarantee that center configuration self stability does not offset, realize the cartridge bag requirement placed in the middle of presplit blasting Uncoincided charge, reduce blasting process shock wave to the destruction of protective surface, solve the original backwardness of prior art presplit blasting charge process, field fabrication labor intensive financial resources, operating efficiency is low.In powder charge process, to be often difficult to realize not being coupled of presplit blasting powder charge requirement placed in the middle for cartridge bag, and directly contact with big gun hole wall, the high-pressure shocking wave produced makes pre-broken face heavy damage, may cause the destruction of reserved working face, cannot realize the problems such as the design effect of presplit blasting.
Accompanying drawing explanation

Fig. 2 is structure schematic top plan view of the present invention.
Detailed description of the invention
A kind of blast charging structure, it comprises pvc pipe 1, lower tube body offers pvc pipe 1 respectively two disconnected groovings 2 of symmetry, the width of grooving 2 is the 15-25% of pvc pipe 1 diameter, preferably 20%, pvc pipe 1 diameter is slightly less than powder stick diameter, and the symmetrical grooving in pvc pipe 1 two ends forms clamping action to cartridge bag, break into two with one's hands and cartridge bag can be facilitated to load, the self-strength of pvc pipe 1 and interior pressure energy guarantee that cartridge bag is stablized.
Pvc pipe 1 with the body of grooving 2 junction offer fixed card slot 3, fixed card slot 3 internal fixtion has fan-shaped center configuration 4, size and the big gun hole dimension of fan-shaped center configuration 4 agree with, fan-shaped center configuration 4 is made up of outer fan structure and rectangle laminated structure, wherein rectangle laminated structure is laid when powder charge and to be snapped in pvc pipe 1 fixed card slot located vertical with grooving in 3, sector structure is corresponding with big gun hole wall agrees with, and ensures that body is stable and is positioned at Bao Kong center, realize Uncoincided charge.
Laterally make it vertical with tube wall between two parties after the rectangular segment of fan-shaped center configuration 4 of the present invention enters body, utilize the characteristic of rectangle laminated structure and outer fan structural attachments size gradation, fan-shaped center configuration 4 can well be fixed in draw-in groove 3.Break body one end into two with one's hands, by design interval press-in powder stick 5, powder stick 5 is blocked by body own resilience, can not destroy powder stick, guarantees that powder stick can not landing, can control powder stick riding position by grooving on body, adjustment powder charge interval.
After having assembled, powder stick body directly will be with to send in big gun hole, without the need to tying up or other operations, simple to operate, realize Uncoincided charge and the spaced loading of presplit blasting design.
