Description
Technical field
The present invention relates to water coincidence smooth Surface Blasting Technology fields, and in particular to a kind of water coincidence smooth surface for horizontal blasthole
Demolition set.
Background technique
During Tunnel Blasting, out break, blast fragmentation size, Half cast factor, single drilling depth and blast hole utilizing factor etc. are difficult to control,
Affect construction cost and progress；Meanwhile blasting dust also threatens to the health of operating personnel and to ambient enviroment
It damages, the increase of ventilation time also affects blast working progress.
Summary of the invention
Invention is intended to provide a kind of water coincidence photoface exploision device for horizontal blasthole, water coincidence photoface exploision skill herein
The use of art increases the utilization rate of explosive energy, greatly reduction Dust Capacity, accelerates construction progress, reduces construction cost, also protect
The safety of operating personnel is demonstrate,proved.
The technical solution of the present invention is as follows: a kind of water coincidence photoface exploision device for horizontal blasthole, including water pipe and
Level opens up blasthole, and water pipe is closed at one end, and the water pipe other end is provided with inlet opening, suitable in water pipe by inlet opening
Sequence is provided with multiple blastings charge, and multiple blastings charge are sequentially connected by primacord, is additionally provided on water storage tube wall for seeing
The strip groove for examining the blasting charge in water pipe, in water pipe side, inner wall is additionally provided with for fixing blasting charge card hole, in detent
Detent wedge is provided in hole, detent wedge passes through in card hole insertion pack, and water storage pipe diameter is less than blasthole diameter.
Preferably, it is observed by strip groove and facilitates shifting according to demand in the position of the bar shaped groove width about 1cm, pack
It is dynamic.
Preferably, the distance between adjacent card hole, which is greater than, presets the distance between axially adjacent water coincidence blasting charge, and
And the sum of the distance between 3/2 times less than explosive packet length and the adjacent blasting charge.
It after the completion of described device powder charge, is sent directly into blasthole after can first filling water, uses water pipe after can also being sent into blasthole
It is filled the water across inlet opening into water pipe.
By adopting the above technical scheme, it is " water wedge " effect by " gas wedge " the broken rock role transformation of Air Coupling explosion, increases
The utilization rate of explosive energy, greatly reduction Dust Capacity, accelerate construction progress, reduce construction cost, also protect operating personnel
Safety.
Detailed description of the invention
Fig. 1 blasting charge structural schematic diagram of the present invention；
Fig. 2 present invention does not have blasting charge structural schematic diagram；
Wherein: 1- water pipe, 2- detent wedge, 3- card hole, 4- strip groove, the inlet opening 5-, the 6- blasting charge, 7- primacord.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
Please refer to Fig. 1, Fig. 2, a kind of water coincidence photoface exploision device for horizontal blasthole, including water pipe 1 and level
Blasthole is opened up, water pipe 1 is closed at one end, 1 other end of water pipe is provided with inlet opening 5, through inlet opening 5 in water pipe 1
Multiple blastings charge 6 are sequentially set with, multiple blastings charge 6 are sequentially connected by primacord 7；
It is additionally provided with the strip groove 4 for observing the blasting charge in water pipe on 1 tube wall of water pipe, certain strip groove 4 is along water storage
The axial setting of pipe 1, can observe the facilities of whole blastings charge in water pipe in this way；
It is additionally provided on 1 side inner wall of water pipe for fixing blasting charge card hole 3, detent wedge 2 is provided in card hole,
Detent wedge 2 is in pyramid type, and detent wedge tip 2 passes through card hole 3 and is inserted into the blasting charge, the blasting charge is fixed；
1 diameter of water pipe is slightly less than blasthole diameter.
Preferably, the blasting charge is observed by strip groove in the position of 4 width of the strip groove about 1cm, the blasting charge, and according to need
It asks and is moved easily.
Preferably, the distance between adjacent card hole 3 is greater than the distance between adjacent blasting charge of default axial water coincidence, and
And the sum of the distance between 3/2 times less than explosive packet length and the adjacent blasting charge.
Working principle: after the position of the blasting charge determines, the blasting charge and primacord are bound, by the blasting charge bound and led
Quick-fried rope is put into water pipe from inlet opening, by the position of the mobile blasting charge of strip groove, uses detent after determining the position of the blasting charge
Wedge passes through in card hole insertion pack and fixes explosive package location, and the water pipe for installing the blasting charge is put into blasthole, is worn with water pipe
Entering inlet opening to fill the water into water pipe, strip groove is kept upward, and water pipe fills and water pipe is slowly pushed into blasthole bottom after water,
It is clogged later.
