Description
Technical field
The invention belongs to explosion powder stick fields, and in particular to a kind of cumulative waterpower control explosion powder stick.
Background technique
Conventional CUMULATIVE BLASTING method is broadly divided into two classes: grooving hole CUMULATIVE BLASTING, Concentrated charge CUMULATIVE BLASTING.Grooving hole is poly-
Can explosion need using specific drilling tool the preparatory grooving in drilling, difficulty of construction is big, low efficiency, at high cost；Concentrated charge cumulative
Explosion be then when processing powder stick, or scene powder stick is loaded into in crannied binding energy tube, sent according to directional fracture direction
Enter in drilling, forms perforation crack when explosion, but the CUMULATIVE BLASTING technology of cumulative powder stick needs to process special cumulative in advance
Pipe, at high cost, in-site installation is more difficult, and is air in sockets for collecting energy, light-weight, kinetic energy is small, and CUMULATIVE BLASTING effect needs to be mentioned
It is high.
Summary of the invention
The object of the present invention is to provide a kind of cumulative waterpower control explosion powder stick, technical principle are as follows: when explosive roll forming
Cumulative chamber is arranged symmetrically in the elongated range in powder stick two sides, cumulative is intracavitary to be equipped with water, and the detonation wave that powder stick explosion time generates, moment will
The intracavitary water of cumulative flocks together, and orients at the precracking for rushing at the wall of a borehole two sides with high-voltage high-speed, i.e., high-pressure hydraulic is penetrated
Stream cutting rock, forms crack, and water enters wherein, and the high pressure gas for generation of exploding is expanded along joint-cutting, crack is extended, finally
Connectivity crack is formed with adjacent drilling, achievees the purpose that photoface exploision or presplit blasting.
The technical scheme adopted by the invention is that a kind of cumulative waterpower controls explosion powder stick, including cylindrical powder stick ontology
And outer packaging bag, outer packaging bag is embedded to be cased with powder stick ontology, has been symmetrical set arcwall face in powder stick ontology, and arcwall face is by powder stick
Body interior is sequentially divided into the first cumulative chamber, explosive chamber and the second cumulative chamber, wherein in the first cumulative chamber and the second cumulative chamber
Interior medium is the fluid that density is greater than air, and the intracavitary medium of explosive is aqueous gels or emulsion.
The features of the present invention also characterized in that
Outer packaging bag thickness outside the side wall that explosive chamber connects with powder stick ontology is not less than the first cumulative chamber and the second cumulative
Outer packaging bag thickness outside the side wall that chamber connects with powder stick ontology.
First cumulative chamber, explosive chamber and the second cumulative chamber are connected but are not connected to mutually.
The invention has the advantages that
The powder stick controls explosion by cumulative waterpower and increases high pressure jet flow and water wedge effect, improves photoface exploision
Or the effect of presplit blasting, explosive consumption is reduced, blasting boreholes spacing is increased, reduces boring work amount, and quick-fried
Water mist and vapor are formed in fried, are played the role of depositing dust, are improved operating environment.

Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
A kind of cumulative waterpower of the present invention controls explosion powder stick, as shown in Figures 1 and 2, including cylindrical powder stick ontology 3 and outer
Packaging bag 1, outer packaging bag 1 is embedded to be cased with powder stick ontology 3, and outer packaging bag 1 is closed at both ends, and powder stick ontology 3 includes explosive chamber 5, the
One cumulative chamber 2 and the second cumulative chamber 4, have been symmetrical set arcwall face in powder stick ontology 3, arcwall face by inside powder stick ontology 3 according to
Secondary to be divided into the first cumulative chamber 2, explosive chamber 5 and the second cumulative chamber 4, explosive chamber 5 is located at the first cumulative chamber 2 and the second cumulative chamber 4
Between, the first cumulative chamber 2, explosive chamber 5 are connected with the second cumulative chamber 4 but are not connected to mutually；Each first cumulative chamber 2 and each
Medium in second cumulative chamber 4 is the fluid that density is greater than air, and the medium in each explosive chamber 5 is aqueous gels or emulsification
Explosive.
Wherein, the fluid that density is greater than air includes water, vapor or oil etc.；Preferably, each first cumulative chamber, 2 He
Medium in each second cumulative chamber 4 is water；
1 thickness of outer packaging bag outside the side wall that explosive chamber 5 connects with powder stick ontology 3 is not less than the first cumulative chamber 2 and second
1 thickness of outer packaging bag outside the side wall that cumulative chamber 4 connects with powder stick ontology 3；
A kind of cumulative waterpower of the present invention controls explosion powder stick, specifically used method are as follows:
As shown in figure 3, set blasting boreholes 6 on object to be blasted, determine the direction of explosion presplitting joint-cutting 7 i.e.,
Explosion powder stick is installed in blasting boreholes 6 by explosion requirement cutting ferrule, long bamboo chip, fixed link, fixing pipe etc., is installed
When, as shown in figure 4, the first cumulative chamber 2 and the second cumulative chamber 4 of explosion powder stick with i.e. explosion presplitting joint-cutting direction 7 is parallel, most
Sealing of hole is carried out to blasting boreholes 6 with stemming afterwards, by explosion requirement explosion.
The first cumulative chamber 2 and the second cumulative chamber 4, the first cumulative chamber 2 are arranged symmetrically when explosive roll forming in powder stick ontology 3
It is provided with water with the second cumulative chamber 4, the detonation wave that powder stick explosion time generates, moment will be in the first cumulative chamber 2 and the second cumulative chamber 4
Water flock together, and orient and rushed at high-voltage high-speed at the precracking of the wall of a borehole two sides, i.e., high pressure jet flow cuts rock
Stone, formed crack, water enter wherein, the high pressure gas for generation of exploding is expanded along joint-cutting, crack is extended, finally with adjacent brill
Hole forms connectivity crack, achievees the purpose that photoface exploision or presplit blasting.
