Description
Technical field
The utility model belongs to the packing and the blasting engineering technology of applicable industry emulsion, belongs to civil explosive material and blasting engineering technical field.
Background technology
Along with the high speed development of Chinese national economy, to the construction of coastal (inland river) harbour, navigation channel and defence engineering, the explosion of deep-sea (deep water) increases; Deep-sea (deep water) explosive use amount straight line rises; But in the explosion of deep-sea (deep water), there is the powder charge difficulty, because powder charge is bad always; Have a strong impact on construction quality and progress, fettered the blasting engineering operation of deep-sea (deep water).
Though emulsion develops towards loading in mixture car mechanized charging direction; But the emulsion that loads in mixture car production is rarer because of the medicine attitude, and water resistance is bad, and mixed explosive is in deep water in addition; The sensitivity of explosive shows the person and reduces, and the deep water explosion is still basically adopts manual powder charge and explosion.
Deep-sea (deep water) blast charging generally has two kinds of forms: a kind of is that the bar shaped explosive charge is bundled on the finished mao bamboon, reinstalls the big gun hole; Another kind is to use sleeve pipe, and explosive is packed in the sleeve pipe, from sleeve pipe explosive is pushed in the big gun hole.Two kinds is the method for current deep water powder charge, and advantage and limitation are all arranged, but needs of incompatibility existing situation development all.
Use the mao bamboon processing method: be hole pattern parameter, order the explosive of special packing, process two kinds of paraffin paper and plastic barrel packings as required according to blasting Design; Generally convenient for powder charge, design big gun hole is as being ￠ 110mm diameter, and the buying explosive is just to be ￠ 70mm specification; According to loaded length, process the mao bamboon of a semicircle (or 1/3 circle), one one of bar shaped explosive charge is bundled on the mao bamboon; And then load onto initiating equipment, by the diver big gun hole of packing into.This process is difficulty and very long very, and first explosive itself is softer, the binding difficulty; Its two since the softer dress initiating equipment of explosive also the difficulty; Its three explosive be packaged as paraffin paper, soak through deep water, as long as have medicine pack into the big gun hole just must several little in; Adorned whole big gun holes; Otherwise maybe the explosive waterproof and lost efficacy in beginning powder charge hole, packs with plastic barrel, though water resistance is strengthened; But the smooth cunning of crust, binding, processing are also very difficult.
Use the sleeve pipe loading method: after accomplishing fluently the big gun hole, the strip medicine is packed in the sleeve pipe, reach in the big gun hole, then a rule explosive is pushed the big gun hole by sleeve pipe from ship; Every explosive all must slowly be packed into, mainly is the resistance owing to water, and every explosive resembles a plunger, can only slowly push; Otherwise Explosive roll can break, as meets thick and heavy slime water is arranged in the big gun hole, in sleeve pipe, pushes tens medicines; Very difficult, and cause the powder stick distortion easily, powder charge was lost efficacy.As the explosive that adopts plastic barrel to pack, intermediate medium has plastics, water, and explosive sensitivity in deep water itself will reduce, the influence of medium in addition, explosive sensitivity can further reduce.

(2) processing difficulties: the explosive of a rule is bundled on the mao bamboon; No matter be paraffin paper and plastics package, explosive generally is an emulsion, and powder stick all is soft; Powder stick is through carrying several times; Sensitizer in the emulsion changes certainly, and sensitization and powder stick impaired impacts to blasting quality.
(3) cost rises: the explosive of a rule is bundled on the mao bamboon, what generally adopt is adhesive tape, and the material of binding is also higher than explosive cost sometimes, causes blasting cost to rise, and serious environment pollution.
(4) adopt the sleeve pipe powder charge, sleeve pipe adds the weight of explosive, and sleeve pipe has some deflection when getting into the big gun hole, collide out some stone, and sleeve pipe has just entered not the big gun hole, is stuck in the big gun hole difficult treatment.
(5) two kinds of method powder charges, explosive all is discontinuous, between bar and the bar, distance is arranged and have the medium of water to intercept, and explosive sensitivity is influenced, and demolition effect is not good yet.
(6) two kinds of method powder charges, it is all difficult that initiating equipment is installed, and do not stay the position on the packing.
