Abstract
The invention relates to a circular disc for cutting a concrete pipe. The circular disc comprises an energy-gathering explosive disc, an explosive type cover, protective steel plates, logs, a blasting cap and iron hoops, wherein the energy-gathering explosive disc is in a circle shape, the periphery of the energy-gathering explosive disc is inwards concave to a center shaft of the energy-gathering explosive disc to form a V shape or C-shaped groove, the upper disc surface and the lower disc surface are parallel and are respectively provided with one protective steel plate, the protective steel plates are respectively connected with the logs, the inside of the groove of the energy-gathering explosive disc is provided with the explosive type cover which is attached with the energy-gathering explosive disc, the center shaft of the energy-gathering explosive disc is provided with the blasting cap, and the iron hoops are respectively arranged on the areas, 8-15 cm away from the upper part and lower part of the preset cutting area, of the outer wall surface of the concrete pipe. The circular disc has the advantage that through the strong function of detonation products and high-speed jets generated during the charging explosion of the circular disc, the concrete pipe is separated into two parts, so the labor strength is reduced, the working efficiency is improved, and the affecting range of the explosion can be strictly controlled.
Description
Technical field
The present invention relates to the controlled blasting technology, relate in particular to the pipe of concrete cutting disc.
Background technology
In people's production and life, often have a large amount of pipe of concretes to need cutting, the way of people's hammering commonly used in the past is isolated into two parts, this not only labour intensity in, inefficiency, and the personal safety in workman construction is difficult to be protected, and surrounding environment is caused adverse effect.
By utilizing the rule that the detonation product direction of motion is vertical with charge surface or cardinal principle is vertical, can make the powder charge of special shape, detonation product is gathered together to move towards certain orientation, improve energy-flux density, strengthen blasting effect, this is the CUMULATIVE BLASTING effect, and correspondingly this powder charge is called beehive-shaped charge; Layout of linear shaped charge is a kind of of beehive-shaped charge, and it is to be cut with before the object plane that forms through crack by layout of linear shaped charge is placed in, and the object cutting can be come; Simultaneously, the immense pressure of the detonation product that produces of explosive charge 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 addressing the above 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 be "＜" or " (" connected in star, its up and down card is parallel and be equipped with described steel backplate; Described steel backplate all is connected with described round log; Be provided with the described cavity liner that sticks together with it in the groove of described cumulative batch pan; Described detonating capsule is housed on the central shaft of described cumulative batch pan; Described iron hoop is located at respectively 8～15cm place of the up and down, outside wall surface preset distance cut place of pipe of concrete.
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 the described steel backplate of 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 the steel backplate, therefore, can play location and fixation to cumulative batch pan and steel backplate.
2, owing to having steel backplate, round log and iron hoop on cumulative batch pan in the present invention; therefore; it is that cumulative batch pan institute is in the zone that steel backplate and round log are limited in zone between the steel backplate of up and down with the high pressure detonation gas; strictly controlled the coverage of detonation; pipe of concrete outside wall surface iron hoop plays a protective role to pipe of concrete in addition, and pipe of concrete other zone is well protected.
3, one aspect of the present invention by adopt around the cumulative batch pan with "＜" or " cavity liner that (" connected in star is complementary, when detonator detonates at cumulative batch pan center, high pressure, at a high speed, high-octane energy-gathering jetting with 360 ° be whole circumference radially as sharp knife the Concrete Cutting pipe form joint-cutting; On the other hand, in 360 ° of scopes of all-round length, detonation gas is the inwall of cumulative batch pan corresponding region with the zone that high pressure vertically acts between the steel backplate of pipe of concrete up and down, and this radial pressure causes the pipe of concrete hoop tension, impels pipe of concrete fracture propagation, extension.
3, after employing the present invention, can reduce labor intensity, increase work efficiency.
Description of drawings
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.
The specific embodiment
As shown in Figure 1, the 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 be "＜" or " (" connected in star, its up and down card is parallel and be equipped with steel backplate 6; Steel backplate 6 all is connected with round log 7; Be provided with the cavity liner 4 that sticks together with it in the groove of cumulative batch pan 3; Detonating capsule 5 is housed on the central shaft of cumulative batch pan 3; Iron hoop 8 is located at respectively the outside wall surface 2 8～15cm places of preset distance cut place Shang Xia 9 of pipe of concrete 1.
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 the 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.
During use, the present invention is placed in pipe of concrete 1, makes "＜" or " (" connected in star is aimed at predetermined cuts place 9, and settles simultaneously round log 7 to be connected with steel backplate 6, and then fixing iron hoop 8, complete every preparation of detonating.So far, the cumulative batch pan 3 of detonating is implemented explosions, energy-gathering jetting with 360 ° be whole circumference radially as sharp knife when Concrete Cutting pipe 1 predetermined cuts place 9, detonation gas is to pipe of concrete 1 generation strong effect, impel pipe of concrete 1 to form joint-cutting, and expansion and extension.Simultaneously, steel backplate 6, round log 7 and iron hoop 8 have strictly been controlled the coverage of detonation, and pipe of concrete 1 is played a protective role.
