Abstract
The utility model relates to a specific application of blasting technology, in particular to the forming blasting on rock. The utility model provides a rock blasting splitting pipe aiming at leading the blasting efficiency of the rock splitting pipe to be higher and increasing the distance between blastholes so as to reduce the numbers of the blastholes. The utility model includes a column circular tube, parallel clapboards arranged in the column circular tube and a buffer medium filled between two parallel clapboards and the circular tube. The pipe is characterized in that two cumulative spaces formed by a circular tube wall and symmetrical and cone angle shaped end clapboards arranged between the two parallel clapboards and the circular tube wall; the filled explosives are arranged between the two parallel clapboards and the two end clapboards.
Description
Technical field
The utility model is the application-specific of blasting technique, is particularly useful for the shaping blasting to rock.
Background technology
The inventor discloses the utility model patent that a name is called the explosion splitter in 1993, its patent No. is ZL93204316.X, this explosion splitter comprises the cylindricality pipe, the buffer medium of filling between two parallel baffles and dividing plate and the pipe is set within it, with this explosion splitter exploitation stone material, can prevent that stone material from causing when explosion shatters, and molding effect is better; But it also has the following disadvantages, though the structure of this explosion splitter has when explosion along the effect of the direction cracking of setting, but because this structural reason, energy when the explosive charge in the splitter also is not fully utilized, so that on the rock distance between adjacent two blast holes can't elongate to longer length.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and a kind of rock blasting split tube with cumulative structure is provided, because the cumulative action of its structure makes blasting efficiency higher, the distance on the rock between adjacent two blast holes is bigger; When increasing blasting efficiency,, can also achieve the above object with shock-absorbing and the good filling medium of shock-absorbing capacity in order further to improve the quality of explosion face.
The utility model can reach by following measure: a kind of rock blasting split tube, comprise the cylindricality pipe, the buffer medium of filling between two parallel baffles that are provided with within it and the pipe, it is characterized in that: between two parallel baffles and tube wall, be provided with two by the taper angle shape of pipe wall and symmetry or the cumulative space that semicircular endplate constitutes, be the explosive of filling between two parallel baffles and two endplates.On the basis of said structure, can also be with expanded perlite or expanded vermiculite as filling medium.
The utility model advantage compared with prior art is: because the utility model is provided with two cumulative spaces between two parallel baffles and tube wall, when explosive charge, on the taper angle shape of symmetry or semicircle endplate, produce jet, itself and big gun hole wall collision back form stagnation pressure, at first on hole wall, cut out the crack, and then its detonation gas quasi static pressure acts on hole wall, the cutting crack is further enlarged, between two big gun holes, connect, not only can play the direction of determining presplitting by the effect in above-mentioned visible this cumulative space, also because it has increased the shaping blasting energy, therefore, can increase big gun hole pitch-row reaches about one times, in addition, since the utility model with expanded perlite or expanded vermiculite as the filling buffer medium, these two kinds of materials are compared with other materials (as air or water), its shock-absorbing performance and damping performance are better, after the explosion, the big gun hole wall relative with buffer medium is complete, flawless, guarantee blasting quality, because expanded perlite or expanded vermiculite chemical stability are good, do not react again with explosive, so the utility model product memory property is good.
Description of drawings
The accompanying drawing drawing is described as follows:
Fig. 1: the schematic cross section of a kind of rock blasting split tube of the utility model
The specific embodiment
(accompanying drawing) will the utility model is described in further detail now in conjunction with the embodiments:
As shown in the figure: 1 is the cylindricality pipe, 2 is two parallel baffles that are set in parallel in the pipe 1,3 for the buffer medium of filling between dividing plate 2 and the pipe 1 it can be the expanded perlite (also can be expanded vermiculite) that mixes filling afterwards with adhesive, because the chemical stability of these two kinds of materials is higher, and its damping performance and shock-absorbing capacity also relatively good 5 are the cumulative space, 4 is the endplate between the explosive 6 of cumulative space 5 and filling, this endplate is symmetrical taper angle shape (also can be semicircle), its two parallel baffle and endplate and pipe all are to make with paper or plastics, link with bonding form between them, be filling explosive between the endplate 4 of cone angle two parallel baffles 2 and two.
Claims (2)
1, a kind of rock blasting split tube, comprise cylindricality pipe (1), the buffer medium (3) of filling between 1 its interior two parallel baffles (2) that are provided with and dividing plate and the pipe, it is characterized in that: between two parallel baffles and tube wall, be provided with two by the cumulative space (5) of pipe wall, be the explosive of filling (6) between two parallel baffles and two endplates with taper angle shape that is symmetry or semicircular endplate (4) formation.
2, a kind of rock blasting split tube according to claim 1 is characterized in that: described buffer medium (3) is expanded perlite or expanded vermiculite.
