Description
Technical field
The present invention is applied to blasting engineering and demolition set technical field, and in particular to a kind of brill for blasting engineering
Hole pack.
Background technique
As the basic demand of engineering explosion technology, the excavation of rock requires rock broken, throwing by design requirement, with shape
The ground structures of Cheng Xin, and outside the rock mass range of engineering design, then destruction of the explosion to rock mass is avoided to the maximum extent
And damage.Since last century, many countries have carried out a large number of experiments research to photoface exploision and presplit blasting in succession.Mesh
Before, China is in excavation construction, and photoface exploision and presplit blasting are being popularized in an all-round way, gradually and at the construction party of standard
Method.
Photoface exploision and presplit blasting are born in the pursuit of explosion people, grow up, is mature.Photoface exploision is excavated along design
Intensive blasthole is laid on boundary, using Uncoincided charge or filling low-strength explosive, detonate after the explosion of the area Zhu Bao to be formed
The bursting work of smooth outline excavation.Presplit blasting is to excavate boundary along design to arrange intensive blasthole, takes Uncoincided charge
Or filling low-strength explosive, it detonates before the area Zhu Bao, so that precracking is formed between quick-fried area and reserved area, it is quick-fried to weaken master
It breaks the destruction to reservation rock mass and forms the bursting work in planar profile face.Photoface exploision and presplit blasting are widely used in underground
With oprn-work engineering.
In recent decades, China has carried out a large amount of reality to blast mechanism, charge constitution, blasting parameter of the explosion time difference etc.
Research is tested, the photoface exploision medicine dedicated that low-density, explosion velocity are low, detonation is stable is had developed, to coupling charging and Uncoincided charge
Condition has all done careful enough interior and field experiment research.But at present in engineer application, few explosive energy
Enough reach the Smooth Blasting Effects of practical function, to find out its cause, there is also blastholes in addition to firing order and the time difference, problem of management
Blast action directional problems, the explosive effect problem of explosion pack.
It is provided based on the above problem present in blasting engineering under present condition the present invention is directed to improve demolition effect
A kind of drilling pack for blasting engineering.
Summary of the invention

It is bored with hand-held impact, desk-top drill carriage can be used in rock gangway.
A kind of drilling pack, drill pipe are different from joint-cutting pipe, need symmetrically to be drilled with 10-20 in drill pipe two sides
The small bore that radius is about 1-3cm.
A kind of drilling pack, explosive use cylindric primacord, are placed in drill pipe, primacord diameter is less than
Drill pipe, using the form of Uncoincided charge.
A kind of drilling pack is protected using explosion-proof gasket in the filling mouth of explosive, is prevented in blast process
The destroying infection of middle explosive and detonator to remaining orientation.
The ignition of a kind of drilling pack, explosive is ignited using detonator, the extension split-phase of detonator and explosive
Even, detonator is using detonator connection detonation.
A kind of drilling pack needs to carry out filling processing when arranging explosive, and padding can be used
The forms such as plasticine, fine sand.
As a further improvement of the present invention and illustrate:
Preferably, seamless connectivity is used between the blasthole and drill pipe.
Preferably, the bradawl pitch of holes being arranged on drill pipe is 4-6 times of bradawl bore dia.
Preferably, air can be used between the explosive and drill pipe, remaining medium can also be used and be filled.
Preferably, the plasticine and fine sand as padding when need that bonding is fixed with glue.
Preferably, the explosion-proof gasket can be using the irony square plate equipped with drilling.
Preferably, it needs to fix using insulating tape between detonator and explosive.
Preferably, it in porous situation, needs to consider the problems of while detonating, two detonators is connected into the same thunder
Pipe is ignited.
A kind of drilling pack of the present invention, using producible the utility model has the advantages that
A kind of drilling pack for blasting engineering can accurately hold explosion direction in blasting process,
Explosion energy more accurately dredged, it is strong through effect to rock in practical application effect, through direction crackle is bright
It is aobvious, explosive effect is significant, there is great directive significance to the bursting work in rock tunnel engineering；Drilling pack of the invention, system
Facilitating, arrangement is simple, and it is low in cost, have the condition and value being widely popularized.
