Abstract
The present invention relates to a kind of pipe of concrete cutting disc, it comprises cumulative batch pan, cavity liner, steel backplate, round log, detonating capsule and iron hoop.Described cumulative batch pan is rounded, is recessed in " & lt around it in the central shaft of cumulative batch pan; " or " (" connected in star, its upper and lower card is parallel and be equipped with described steel backplate; Described steel backplate is all connected with described round log; The described cavity liner sticked together with it is provided with in the groove of described cumulative batch pan; The central shaft of described cumulative batch pan is equipped with described detonating capsule; Described iron hoop is located at upper and lower 8 ~ 15cm place, the outside wall surface preset distance cut place of pipe of concrete respectively.The strong effect of the detonation product that the present invention utilizes disk charging explosion to produce and high-speed jet, is separated into two parts by pipe of concrete, not only alleviates labour intensity, improve operating efficiency, and strictly can control the coverage of detonation.
Description
Technical field
The present invention relates to Controlled blasting technique, particularly relate to pipe of concrete cutting disc.
Background technology
In the production and life of people, often have a large amount of pipe of concrete to need cutting, the way that people commonly use hammering is in the past isolated into two parts, this not only labour intensity in, inefficiency, and the personal safety in workman's construction is difficult to be protected, and adverse effect is caused to surrounding environment.
By utilizing the rule of the detonation product direction of motion or less perpendicular vertical with charge surface, the powder charge of special shape can be made, detonation product is gathered together towards certain orientation move, improve energy-flux density, strengthen blasting effect, this is CUMULATIVE BLASTING effect, and correspondingly this powder charge is called beehive-shaped charge; Layout of linear shaped charge is the one of beehive-shaped charge, and it is to be cut with before the object plane forming through crack by being placed in by layout of linear shaped charge, object cutting can be come; Meanwhile, the immense pressure of detonation product that explosive charge produces also will produce strong effect to object.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of pipe of concrete cutting disc of effectively increasing work efficiency.
For solving the problem, pipe of concrete cutting disc of the present invention, is characterized in that: it comprises cumulative batch pan, cavity liner, steel backplate, round log, detonating capsule and iron hoop; Described cumulative batch pan is rounded, be recessed in the central shaft of cumulative batch pan around it in " < " or " (" connected in star, its upper and lower card is parallel and be equipped with described steel backplate; Described steel backplate is all connected with described round log; The described cavity liner sticked together with it is provided with in the groove of described cumulative batch pan; The central shaft of described cumulative batch pan is equipped with described detonating capsule; Described iron hoop is located at upper and lower 8 ~ 15cm place, the outside wall surface preset distance cut place of pipe of concrete respectively.
The radius of described steel backplate is less than described pipe of concrete inside radius.
The radius of described round log is identical with described pipe of concrete inside radius.
Little 1 ~ 3 times of described cumulative batch pan height of the radius of steel backplate described in the radius ratio of described cumulative batch pan.
The dead in line of described cumulative batch pan and described steel backplate and described round log.
The present invention compared with prior art has the following advantages:
1, because round log in the present invention is connected with steel backplate, therefore, location and fixation can be played to cumulative batch pan and steel backplate.
2, due to cumulative batch pan in the present invention having steel backplate, round log and iron hoop; therefore; high pressure detonation gas is limited in region between upper and lower steel backplate and cumulative batch pan institute in region by steel backplate and round log; strictly control the coverage of detonation; in addition pipe of concrete outside wall surface iron hoop plays a protective role to pipe of concrete, and other region of pipe of concrete is well protected.
3, one aspect of the present invention by adopt around cumulative batch pan with " < " or " cavity liner that (" connected in star matches, when detonator detonates at cumulative batch pan center, high pressure, at a high speed, high-octane energy-gathering jetting with 360 ° namely whole circumference radial as sharp knife Concrete Cutting pipe formation joint-cutting; On the other hand, within the scope of all-round length 360 °, detonation gas vertically acts on the inwall of region between the upper and lower steel backplate of pipe of concrete and cumulative batch pan corresponding region with high pressure, and this radial pressure causes pipe of concrete hoop tension, impels pipe of concrete fracture propagation, extension.
3, after adopting the present invention, can reduce labor intensity, increase work efficiency.

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
In figure: 1-pipe of concrete 2-outside wall surface 3-cumulative batch pan 4-cavity liner 5-detonating capsule 6-steel backplate 7-round log 8-iron hoop 9-predetermined cuts place.
Detailed description of the invention
As shown in Figure 1, pipe of concrete cutting disc, it comprises cumulative batch pan 3, cavity liner 4, steel backplate 6, round log 7, detonating capsule 5 and iron hoop 8.Cumulative batch pan 3 is rounded, be recessed in the central shaft of cumulative batch pan 3 around it in " < " or " (" connected in star, its upper and lower card is parallel and be equipped with steel backplate 6; Steel backplate 6 is all connected with round log 7; The cavity liner 4 sticked together with it is provided with in the groove of cumulative batch pan 3; Detonating capsule 5 central shaft of cumulative batch pan 3 is equipped with; Iron hoop 8 is located at 8 ~ 15cm place of the outside wall surface 2 preset distance cut place about 9 of pipe of concrete 1 respectively.
Wherein: the radius of steel backplate 6 is less than pipe of concrete 1 inside radius.
The radius of round log 7 is identical with pipe of concrete 1 inside radius.
Little 1 ~ 3 times of cumulative batch pan 3 height of radius of the radius ratio steel backplate 6 of cumulative batch pan 3.
The dead in line of cumulative batch pan 3 and steel backplate 6 and round log 7.
Cavity liner 4 is made up of copper, mild steel, ceramic material.
During use, the present invention is placed in pipe of concrete 1, make " < " or " (" connected in star aim at predetermined cuts place 9, and simultaneously settle round log 7 be connected with steel backplate 6, then fix iron hoop 8, complete every preparation of detonating.So far, the cumulative batch pan 3 that detonates implements explosion, and namely whole circumference radial direction is as sharp knife while Concrete Cutting pipe 1 predetermined cuts place 9 with 360 ° for energy-gathering jetting, and detonation gas produces strong effect to pipe of concrete 1, pipe of concrete 1 is impelled to form joint-cutting, and expansion and extension.Meanwhile, steel backplate 6, round log 7 and iron hoop 8 strictly control the coverage of detonation, play a protective role to pipe of concrete 1.
