Abstract
The utility model relates to a concrete pipe cutting circular disk, which comprises an energy accumulating explosive tray, a liner, steel protective plates, logs, a primer detonator and iron hoops, wherein the energy accumulating explosive tray is circular-shaped; the surrounding of the energy accumulating explosive tray is concave towards a central shaft of the energy accumulating explosive tray to form a '<' or '(' shaped recess; upper and lower tray surfaces of the energy accumulating explosive tray are parallel to each other and both provided with the steel protective plates; the steel protective plates are both connected with the logs; the liner laminated with the recess is arranged in the recess of the energy accumulating explosive tray; the primer detonator is mounted on the central shaft of the energy accumulating explosive tray; and the iron hoops are respectively arranged on the outer wall surface of a concrete pipe which is 8-15 cm above and below a preset cutting part. According to the utility model, by using strong effects of detonation products and high speed jet generated by charging explosives on the circular disk for explosion, the concrete pipe is separated into two parts; therefore, the labor intensity is reduced, the working efficiency is increased, and the explosion influence coverage can be strictly controlled.
Description
Technical field
The utility model relates to the controlled blasting technology, relates 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 past people hammering commonly used separates into two parts with it, and not only labour intensity is big for this, inefficiency; And the personal safety in the workman construction is difficult to be protected, and surrounding environment is caused adverse effect.
Through utilizing vertical with charge surface or the vertical substantially rule of the detonation product direction of motion; Can make the powder charge of special shape; Detonation product is gathered together towards the certain orientation motion, improve energy-flux density, strengthen blasting effect; This is the CUMULATIVE BLASTING effect, and correspondingly this powder charge is called beehive-shaped charge; Linear beehive-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 through linear beehive-shaped charge is placed, and can the object cutting be come; The immense pressure of the detonation product that simultaneously, explosive charge produced also will produce strong effect to object.
The utility model content
The utility model technical problem to be solved provides a kind of pipe of concrete cutting disc of effectively increasing work efficiency.
For addressing the above problem, the described pipe of concrete cutting disc of the utility model is characterized in that: it comprises cumulative batch pan, cavity liner, steel backplate, round log, detonating capsule and iron hoop; Said cumulative batch pan is rounded, be recessed in the central shaft of cumulative batch pan around it and be " < " or " (" connected in star, card is parallel and be equipped with said steel backplate up and down for it; Said steel backplate all is connected with said round log; Be provided with the said cavity liner that sticks together with it in the groove of said cumulative batch pan; Said detonating capsule is housed on the central shaft of said cumulative batch pan; Said iron hoop is located at 8～15cm place up and down, outside wall surface preset distance cut place of pipe of concrete respectively.
The radius of said steel backplate is less than said pipe of concrete inside radius.
The radius of said round log is identical with said pipe of concrete inside radius.
Little 1～3 times of said cumulative batch pan height of the radius of the said steel backplate of the radius ratio of said cumulative batch pan.
The dead in line of said cumulative batch pan and said steel backplate and said round log.
The utility model compared with prior art has the following advantages:
1,, therefore, can play location and fixation to cumulative batch pan and steel backplate owing to round log in the utility model links to each other with the steel backplate.
2, owing to have steel backplate, round log and iron hoop on the cumulative batch pan in the utility model; Therefore; Steel backplate and round log are limited in the high pressure detonation gas up and down, and the zone between the steel backplate is that cumulative batch pan institute is in the zone; The coverage of detonation has been controlled in strictness, and pipe of concrete outside wall surface iron hoop plays a protective role to pipe of concrete in addition, and other zone of pipe of concrete is well protected.
3, the utility model on the one hand through 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 is that whole circumference is radially cut pipe of concrete and formed joint-cutting as sharp knife with 360 °; On the other hand; In complete 360 ° of scopes of girth; Detonation gas with high pressure vertically act on pipe of concrete up and down the zone between the steel backplate be the inwall of cumulative batch pan corresponding region, this radial pressure causes the pipe of concrete hoop to be drawn, and impels pipe of concrete fracture propagation, extension.
3, behind employing the utility model, can reduce labor intensity, increase work efficiency.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Among the 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 and be " < " or " (" connected in star, card is parallel and be equipped with steel backplate 6 up and down for it; 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 the 8～15cm place of outside wall surface 2 preset distance cut places about in the of 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 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.
Cavity liner 4 is processed by copper, mild steel, ceramic material.
During use, the utility model is placed pipe of concrete 1, make " < " or " (" connected in star is aimed at predetermined cuts place 9, and settles round log 7 to link to each other with steel backplate 6 simultaneously, fixing iron hoop 8 then, each item preparation that completion is detonated.So far; The cumulative batch pan 3 of detonating is implemented explosions, and energy-gathering jetting is whole circumference when radially as sharp knife, cutting pipe of concrete 1 predetermined cuts place 9 with 360 °, and 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, the coverage of detonation has been controlled in steel backplate 6, round log 7 and iron hoop 8 strictnesses, and pipe of concrete 1 is played a protective role.
