It puts down and is separated by sand bed between blocking up, the desensitized explosive is equipped with secondary priming, and the pair priming is described blunt equipped with detonator
It is separated by aluminium flake between sense explosive and sand bed, between secondary priming and desensitized explosive, between detonator and secondary priming, it is described
Space filling concrete between detonator and PVC pipes.
Preferably, the top of the sand bed puts down stifled top with PVC and maintains an equal level.Preferably, the detonator is that 8# standards are led
Booster detonator.
Preferably, the 8# standards Nonel detonator is located at the shaft core position of PVC pipes, the 8# standards detonator thunder
The length of the detonator of pipe is 5-10m.
Preferably, detonator is completely covered the cement.
Preferably, the secondary priming uses three ammonium nitrate of ring trimethylene.
The present apparatus carries out the process of underwater explosion test experiments and principle is：Studies have shown that the explosive of small pit goaf by
It can be achieved on complete detonation under conditions of certain constraint.Therefore, in limited water field explosion pond, a certain depth carries out insensitiveness
When explosive underwater explosion is tested, first a certain amount of sand is put into PVC pipes, until height maintains an equal level with flat stifled top, at this point, blunt
Constraints is consistent suffered by sense explosive, and is put into an aluminium flake and is entered wherein, is pressed lightly on, is kept its smooth；It is then placed in
A certain amount of desensitized explosive, it is desirable that each place is uniformly, seamless, places into aluminium flake, presses lightly on, holding surface is smooth；It
A certain amount of RDX is added thereto afterwards, is put into aluminium flake, is pressed lightly on；8# standard Nonel detonators are put into PVC pipes
Middle, it is desirable that detonator length is at least 5m, and keeps vertical；The cement just mixed is poured into PVC pipes,
It asks and fills up, be highly more than cap length；To when concrete setting, with exploder detonation tube detonator.
The invention has the advantages that using after this restraint device, realize under conditions of small pit goaf, desensitized explosive in
In underwater explosion test completely detonation this as a result, so as to measure its workmanship ability, and the ability of doing work is that weigh explosive quick-fried
The important performance indexes of broken power, the result measure the energy for being beneficial to make full use of explosive, improve the warp of engineering explosion
Ji benefit.
Description of the drawings
Fig. 1 is that a kind of cross-section structure of the restraint device of test desensitized explosive underwater explosion energy proposed by the present invention shows
It is intended to.
In figure：1, detonator；2, cement；3, PVC is managed；4, aluminium flake；5, secondary priming；6, desensitized explosive；7, sand bed； 8、
PVC is flat stifled.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1, a kind of restraint device of test desensitized explosive underwater explosion energy, including PVC pipes 3, PVC are flat
The bottom end of stifled 8, PVC pipes 3 is sealed by PVC flat stifled 8, and the lower part in PVC pipes 3 is equipped with desensitized explosive 6, to protect
It is identical to demonstrate,prove constraints, is separated by sand bed 7 between desensitized explosive 6 and PVC flat stifled 8, the top of sand bed 7 with
The top of PVC flat stifled 8 maintains an equal level, the constraints being subject to when can ensure 6 detonation of desensitized explosive in this way be it is identical, it is blunt
Feel explosive 6 and is equipped with three ammonium nitrate of ring trimethylene（RDX）5, because 6 detonator 1 of desensitized explosive cannot detonate completely, therefore add
Enter three ammonium nitrate 5 of a certain amount of ring trimethylene and be used for the desensitized explosive 6 that detonates completely, three ammonium nitrate 5 of ring trimethylene is equipped with
Detonator 1, detonator 1 are located at the shaft core position of PVC pipes 3, and the length of detonator is 8m, desensitized explosive 6 and sand bed
Between 7, between three ammonium nitrate 5 of ring trimethylene and desensitized explosive 6, between three ammonium nitrate 5 of detonator 1 and ring trimethylene
Being separated by aluminium flake 4, three ammonium nitrate 5 of ring trimethylene is non-watertight, on the top of pvc pipe 3, PVC pipes 3 and detonator
