Description
Technical field
The utility model relates to a kind of explosive delivery device of tunnel TGP advance geologic prediction, especially a kind of tunnel TGP
Advance geologic prediction excites the explosive in hole to deliver bar.
Background technique
Tunnel Engineering belongs to underground concealed engineering, and underground structure and construction are often complicated and changeable, and TGP advance geologic prediction
Technology has been widely used in the constructing tunnel phase.
TGP Geological Prediction Technology is to generate seismic wave as basic principle using explosive charge, thus need in advance on side
Walled rock position setting excitation hole, and explosive is arranged in hole, the explosive initiation in hole will be excited to produce finally by detonation
Radix Rehmanniae seismic wave.
In excitation hole in terms of the arrangement of explosive, current technical requirements provide that explosive must be necessarily arranged at the bottom hole in excitation hole
Wave is bombarded preferably to generate, however current two existing big defects cause explosive that cannot or be difficult to be delivered to excitation
Hole bottom hole.
First is that currently delivering tool used in explosive is delivery bar identical with receiving transducer is delivered, and this delivery bar
Bayonet length it is too short, explosive can not be all put into bayonet, and bayonet diameter be much larger than explosive diameter, be easy to cause fried
Medicine falls off in distributing procedure；Second is that due to the complexity inside country rock, cause in the drilling pore forming process of excitation hole and pore-forming
Afterwards, there may be pits for the vertical downside hole wall at excitation hole different depth, and when being delivered using above-mentioned delivery bar, explosive holds
It is easy to fall off and be easy to fall into pit due to self weight, finally make explosive that can not be removed and have to be stranded in the pit
And it finally influences to bombard effect.
Utility model content
The purpose of this utility model is to provide a kind of explosives in tunnel TGP advance geologic prediction excitation hole to deliver bar, it
It can prevent explosive from falling off in distributing procedure and pitfall, so that explosive is more accurately delivered to excitation hole bottom hole, more preferably
Ground ensure that effect is bombarded in the detonation of explosive.
The technical solution of the utility model includes: a kind of explosive in tunnel TGP advance geologic prediction excitation hole delivers bar, including leakage
Bucket-shaped outer sleeve passs bar equipped with pushing away of being free to move axially in outer sleeve, the outer surface of outer sleeve is axially disposed have it is continuous
Wire casing.
Described pushing away passs bar as cylindrical base solid insulated plastic charge bar.
Outer sleeve the overall length 220cm, wall thickness 1mm；The cylindrical outer diameter 40mm of outer sleeve big end, axial length are
10cm, conical axial length are 5cm；The cylindrical outer diameter 35mm of small end, axial length 205cm；Cylinder pushes away that pass bar straight
Diameter 30mm, overall length 230cm.
The outer sleeve outer surface line groove width is 4mm.
Compared with the prior art, the utility model has the following advantages:
1, the utility model structure is simple, and novel in design reasonable, execute-in-place is easy.
2, the utility model can fall off in distributing procedure and pitfall defect efficiently against explosive, and explosive can be made more quasi-
It really is posted to the bottom hole in excitation hole, to guarantee good to bombard effect.
3, the utility model production is low with use cost, and functional reliability is high, and long service life, using effect is good, is convenient for
It promotes the use of.
Detailed description of the invention
Fig. 1 is the structural schematic diagram (office is cutd open) of the utility model.
In figure: 1 explosive, 2 outer sleeves, 3 push away and pass bar, 4 wire casings.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is further described through.
As shown in Figure 1, the material and size of the utility model: the material of outer sleeve 2 is antirust galvanized iron sheet, pushes away and passs bar 3
Material is cylindrical base solid insulated plastic charge bar；Outer sleeve 2 is funnel-form, overall length 220cm, wall thickness 1mm；The cylinder of 2 big end of outer sleeve
Shape outer diameter 40mm, axial length 10cm, conical axial length are 5cm；The cylindrical outer diameter 35mm of small end, axial length are
205cm；Cylinder, which pushes away, passs 3 diameter 30mm of bar, overall length 230cm.
Along the continuous wire casing 4 of axial design one on the outer surface of outer sleeve 2, for the detonation conducting wire of explosive 1, wire casing
Width is 4mm.
The utility model is placed horizontally at ground when use, explosive 1 is then placed on to the cylinder of 2 big end of outer sleeve
In part, the detonation conducting wire of explosive 1 is smoothed out with the fingers in the wire casing 4 of outer surface that is suitable and filling in outer sleeve 2, after outer sleeve 2 is delayed
It is slowly inserted in excitation hole, when big end reaches bottom hole and can not continue to promote, then will push away that pass bar 3 straight from the insertion of 2 small end of outer sleeve
Then explosive position into big end pushes away on the other hand and passs bar 3 and pass explosive to push away, the other hand is slowly by outer sleeve 2 toward aperture
Direction is extracted, and when exposed pushing away passs bar 3 completely into outer sleeve 2, explosive 1 pushed away from 2 big end of outer sleeve and reaches hole
Outer sleeve 2 and pushing away is passed bar 3 simultaneously again at this time and exits excitation hole, explosive 1 is completely thus delivered to excitation hole bottom hole by bottom.
Explosive 1 is accurately delivered to bottom hole, the aggregation for bombarding wave energy after explosive 1 explodes is enhanced, can mention significantly
High-energy utilization rate and then the amplitude for reinforcing bombarding spread speed and rock mass particle of the wave energy in rock mass, so that enhancing is broken
Effect；Since bottom hole is a closed scar, and blasthole hole wall is just the critical surface of rock mass and air, i.e. rock mass deformation
The scope of freedom, explosive 1 explode in bottom hole, can greatly improve bombard superpressure that wave generates between bottom hole and aperture director space and
Dynamic pressure can improve the existing energy two of non-bottom hole explosion to (bottom hole to aperture to) weak defect well, and then reinforce
Incident pressure P at hole wallm, transmissive pressure PT, enhance and bombard wave to the length of shot of hole wall and periphery rock mass and being crushed for rock mass
Degree improves crushing effect.
The above is only the preferred embodiment of the utility model, not imposes any restrictions to the utility model, all
According to the utility model technical spirit any simple modification, change and equivalent structure transformation to the above embodiments, still
Belong in the protection scope of technical solutions of the utility model.
