The radian of the arc slab is from 100 to 180 degrees; the arc slab is made of iron sheet or inflammable high-elasticity material; the device can stop and buffer the huge impact to the rocks from the detonation of explosive materials and reduce the shakes to the reserved slope rocks from the detonation; the half-borehole ratio is higher than 93%, a plurality of cracks on the semi-peripheral rocks of the blasthole not only can be avoided, but the accumulated damage to the slope rock from a plurality of detonations also can be avoided; the stability of slope rock detonation and excavation is increased greatly, and the damage to the buildings around is avoided.
Description
Technical field
The utility model relates to a kind of rock mass engineering project Blasting Excavation and uses detonator to cushion the device of short-delay blasting.
Background technology
The water power of China, railway, the non-slope of highway and mine etc. constantly develop in depth, the most of Blasting Excavation that adopts of rock excavation engineering, and thing followed surrounding rock stability problem also highlights day by day.
The vibrations that Blasting Excavation causes are very important influence factors to the stability of surrounding rock body.
Rock mass for different types of structure, the character of its vibrations reaction also is different. the blocky structural rock mass good integrity, deformation behaviour under dynamic action is close to Homogeneous Elastic Solid, stability is better. and the mosaic texture rock mass may cause local avalanche and falling rocks under shock effect, but generally unstable failure can not occur. the cataclastic texture rock mass reacts stronger under shock effect, thereby might becoming flexible of chipping Structure Rock cause large-scale avalanche, falling rocks and small-scale slip. Bedded Rocks is subjected to roofing control, under shock effect, also a large amount of movements may occur.
From the shock-effect that rock mass engineering project blast working excavation produces, the important external factor of adjoining rock stability more and more receives people's concern as an influence.Be necessary to carry out the stable control of concussion of blasting and from more strictly controlled blasting shockproofness of construction technology aspect.
Summary of the invention
In order to address the above problem, it is simple that the purpose of this utility model provides a kind of combination, easy to use, can significantly stop and reduce explosive charge to the resonant interaction of the enormous impact of rock mass generation, reach the purpose of damping, half porosity can reach more than 93 %, not only can avoid rock to big gun hole half periphery to produce a large amount of cracks but also can avoid because the resonance of concussion of blasting accumulated damage that surrounding rock body is produced repeatedly, and reduced the interference effect of detonation stresses ripple, play buffering elementary errors cushioning effect, thereby the utilization detonator that increases considerably the stability of country rock after the rock mass engineering project Blasting Excavation cushions the device of millisecond short delay blasting.
The technical solution of the utility model is: use detonator to cushion the device of millisecond short delay blasting, this device is comprised of arc plate, explosive cartridge, detonator and priming device, described explosive cartridge is fixed on the described arc plate by described detonator, described detonator one end is connected with described explosive cartridge, and the other end is connected with described priming device;
Further, the radian of described arc plate is between the 100-180 degree.
Further, the material of described arc plate is iron sheet or incombustible highly elastic material.
The beneficial effects of the utility model: adopt technique scheme, after the explosion, this device can significantly stop and cushion the energy that explosive blasting discharges, thereby greatly reduce blast to the impact of surrounding rock body, half porosity can reach more than 93%, not only can avoid rock to big gun hole half periphery to produce a large amount of cracks but also can avoid because the resonance of concussion of blasting accumulated damage that surrounding rock body is produced repeatedly, and thereby the interference effect that has reduced the detonation stresses ripple significantly increases the stability of country rock after the rock mass engineering project Blasting Excavation, and economic benefit is huge.
