Description
Technical field
The utility model is related to building fields, more particularly to a kind of high reliability blasting network connection structure of simplicity.
Background technology
The demolition blasting of building, usual surrounding enviroment are complicated, narrow space of collapsing, in collapsing posture and after collapsing
Accumulation scope require it is very high.High-lager building is usually frame-shear structure or shear wall structure, tube structure, this results in unit
The detonator number that volume is consumed increases, and blasting network is larger.Separately the especially complex structure demolition of environment is removed,
Multiple insion folding blasting is mostly used, blasting cut is more, more demanding to blasting network.The demolition blasting of building must ensure
Blasting in once-through success, otherwise, building " quick-fried without fall " or collapse direction and design are inconsistent, will bring tremendous economic
Loss and safety hazard, this is avoided in engineering.
Main blasting network for demolition blasting can be summarized as following 3 class：Electric detonator initiation network, four-way connect non-electrical
Blasting circuit, " greatly grab " cluster connection connection NONEL demolition network.
Electric detonator initiation network advantage is to test with meter check electric cap and to network, inspection side
Just.Disadvantage is then more, and first, electric detonator initiation network, network design requires high, adjustment calculating complexity, mobilization multiple
It is miscellaneous, it is higher to the competency profiling of operating personnel, generally skilled artisan is required to operate, General Explosive person is difficult to win
Appoint；Secondly, electric cap is often sent out there are two payment to a porter, and the connection construction efficiency of detonator wire is slow；Electric cap not anti-stray current,
Safety accident is susceptible under environmental disturbances, therefore more demanding to detonating power supply, it is uncertain larger.Due to electric detonator initiation
There are disadvantages mentioned above at network, therefore are rarely employed in demolition blasting in recent years, and country is even more to be forbidden to use in many areas
Electric cap.
The non-electrical blasting network of four-way connection is each root node four-way 4 detonators in parallel at network, ordinary circumstance
It is lower for " one into, one go out ", two connection downhole explosion detonators are passed to shock wave from a detonator, are connected by network
Contact (four-way), two hair detonator of detonation, while shock wave is spread out of to next network tie point.One, this network four-way can only
Two detonators are connected to, and in Building demolition explosion, often there are thousands of hair detonators, network to connect heavy workload, working efficiency ten
Divide low.And four-way is non-watertight, the waterproof ability at network is poor, easily miss-fires after network is sprayed or drenches with rain by water.This shows
The non-electrical blasting network of four-way connection is not easy enough, and reliability is not also high.
" greatly grab " connection（I.e. cluster joins）Non-electrical blasting network, generally tree or chain structure, or both
Mixing.Using " greatly grab " i.e. cluster connection technology, detonator shares a tie point in 10 ~ 20 hair engaging aperture, and work efficiency is high, and has
Good waterproof effect.However " greatly grab " non-electrical blasting network is used, trunk portion and low level detonating capsule payment to a porter point
It dissipates, detonator wire is complicated and changeable, and it is relatively difficult to carry out " greatly grab " again after combing；Furthermore the detonator at " greatly grab " position,
Easy ting produce high-velocity wire splash in explosion, splash is easy so that periphery detonator is cut off, and causes to miss-fire or blind big gun,
To blasting work, there are some potential safety problemss；Third, propagation of explosion conducting wire can then cause entire once being cut off or failing propagation of explosion
Detonator in " greatly grab " miss-fires, and explosion is caused to fail.The non-electrical blasting network reliability for connection that this shows " greatly grab " is inadequate
It is high.
Therefore, there is an urgent need for a kind of easy reliable easy high reliability blasting network connection structures.
