Description
Technical field
The invention belongs to the packing and the blasting engineering technology of applicable industry emulsion, belong to civil explosive material and blasting engineering technical field.
Background technology
High speed development along with Chinese national economy, construction to coastal (inland river) harbour, navigation channel and defence engineering, the explosion at 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 according to the explosion design, order the explosive of special packing, process two kinds of paraffin paper and plastic barrel packings as required, generally convenient for powder charge, design big gun hole is as being ￠ 110mm diameter, the buying explosive is just to be ￠ 70mm specification, according to loaded length, process the mao bamboon of a semicircle (or 1/3 circle), be bundled in the bar shaped explosive charge on the mao bamboon one by one, 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 may 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, bundle, process 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 from ship, then a rule explosive is pushed the big gun hole by sleeve pipe, every explosive all must slowly be packed into, mainly is because the resistance of water, every explosive resembles a plunger, can only slowly push, otherwise Explosive roll can break, as meet thick and heavy slime water is arranged in the big gun hole, in sleeve pipe, push 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.
Two kinds of charging means cause many defectives:
(1) blast hole utilizing factor is low: design big gun hole is a ￠ 110mm diameter, can only purchase the strip medicine of ￠ 70mm left and right sides specification, reserve the space of mao bamboon or sleeve pipe, just can purchase the strip medicine of the above specification of ￠ 90mm on land, also because the not coupling efficiency in big gun hole is too big, frequent punching during explosion, the energy of explosive all is wasted on report and the water column, and reef explosion irregular, smooth causes the shovel slag to dig the slag difficulty, want positional punch explosion for the second time, cause the huge waste of manpower and materials.
(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, 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 Kun Bang material 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 entering the big gun hole, collide out some stone, and sleeve pipe does not just enter 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.
