Abstract
The utility model relates to a directional blasting structure for celebration, which is used in celebration activities, such as celebrations and the like. The utility model provides a directional blasting structure for celebration, which has convenient construction and good visual effect. A soil blasting pint is dug with a tapered pit of which the upper part is circular, the bottom of the tapered pit is provided with explosive, fine dry soil is arranged above the explosive, and a trigger for igniting the explosive is arranged.
Description
Technical field
The utility model relates to the pyrotechnics facility that uses in the celebrations such as a kind of ceremony.
Background technology
At present, set off the ground explosions of uniformly-spaced delaying of adopting longer distance of large-scale ground breaking ceremony atmosphere by contrast more, but be subjected to factor affecting such as place and weather bigger, when the chance special circumstances must be carried out the ceremony explosion, must take numerous and diverse safeguard measure, bring great influence for construction and progress monitoring, and explosion time is difficult to reach the shock visual effect that native stone flies upward.There is following major defect in it: construct loaded down with trivial details, visual effect is not good.
The utility model content
The technical problems to be solved in the utility model is: the ceremony directional blasting structure that a kind of easy construction, good visual effect are provided.
The purpose of this utility model can reach by following measure: dig system top at the soil blasting point and be circular conical pit, be provided with explosive in described conical pit bottom, described explosive top is provided with thin dry ground, and other is provided with and ignites the trigger that described explosive is used.
The characteristics of technique scheme are: easy construction, the thin dry ground of the explosion time throwing that can make progress fully, form higher throwing face, and reach good visual effect.
Further: described thin dry ground upper surface is a dome.This feature helps described thin dry ground is reached better throwing effect.
Further: for the cartridge bag explosion time can form higher throwing face with the upwards throwing fully of described thin dry ground, the inventor is through repetition test, and determine taper explosion preferable being shaped as in hole: the top diameter of a circle is that 2.5m to 3.5m, the degree of depth are 1m to 2m.
Further: described explosive adopts flat cartridge bag, one by one, side by side, the compact conical pit bottom that is tiled in; Its TNT equivalent is 4.3-7kg.This is that inventor's repetition test draws, the balance preferred value between explosive effect and the consumption.
Further: also be provided with unsettled sky on described conical pit side and hang cartridge bag, to strengthen the auditory effect of explosion.
Further: described thin dry ground upper surface is provided with waterproof layers such as plastics, oilcloth, glass fabric.This feature can prevent to be soaked in water under the waterproof layer.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 cheats the position schematic diagram for overlooking of the utility model embodiment;
Fig. 2 is the orientation of the utility model embodiment explosion hole schematic cross-section that disperses.
The specific embodiment
Known concrete structure and characteristic are no longer set forth at this in this programme.As depicted in figs. 1 and 2: the present embodiment design has eight explosion holes 1 of dispersing, and is two row, four of every row, and spacing is five meters between the hole, per four 1 in blast holes of dispersing are provided with one one kilogram sky extension dobie 2, two altogether.
The disperse main purpose of explosion of orientation is in order to set off opening ceremony atmosphere by contrast, to play up demolition effect, this just requires the shape in explosion hole will satisfy the throwing that the thin dry ground of filling can be made progress fully of cartridge bag explosion time, form higher throwing face, design explosion hole is shaped as: the upper circular diameter is that three meters, the degree of depth are 15 meter explosive funnel shape, adopt flat cartridge bag 3, with its one by one, side by side, the compact bottom, explosion hole that is tiled in, explosive payload is ten kilograms of No. two rock emulsion explosives; Adopt then and take from the thin dry ground 4 that is used for baking bricks that the shale brick field sieves through fragmentation and cover and bury, cover and bury the back and form a circular dome mound with mud; For preventing to rain, after flat cartridge bag 3 covers and buries, thin dry ground 4 is covered with colour bar cloth 5, on 5 of colour bar cloth, cover one deck earth again, enter in the explosion hole 1 of dispersing to prevent rainwater, do not influence the visual effect of burst region before detonating.
Blasting circuit is one of key link that guarantees directed disperse explosion and dobie vision, auditory effect.Its design principle is: practical reliable, accurate quick-fried, easy to operate, in order to be effective safely, satisfy the needs of job site.Present embodiment adopts the highest demolition blasting networking type of skill level, selects for use---and non-electric millisecond detonating networking, blasting circuit adopts half second delay Nonel detonator.The networking connects according to the networking design of each explosion is operated by accredited experienced dynamiter, and blasting engineering the technical staff check.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
