Abstract
A water gun crushing method for dismantling house, mining or dredging features that the pressure generated by explosion of explosive in water gun acts on the medium in hole to crush the object to be crushed. Said water gun is composed of canal, shooting tube and breech, and can be inserted in hole in the object to be crushed after charged. Its advantages are high crushing effect and safety and low cost.
Description
Water gun crushing method and device invention belong to the crushing technology of rock or concrete etc., are mainly used in hard objects such as fractured rock and concrete.
Often run into various ground and concrete etc. in mining, water power excavation and the urban construction and need fragmentation, conventional method mainly is short hole blasting method, adobe blasting method, because the explosive charge of these two kinds of methods is big, thereby slungshot, noise arranged, cost is also higher, and operation is subjected to the surrounding environment restriction.Mechanical Method such as wind or surge rubble method, split the law etc. though there is not slungshot, need task equipment, lack maneuverability.Chinese patent 86209430.5 (EZLC37/12) has proposed a kind of " high hydraulic pressure breaks the rock device ", and it is to utilize petrosal foramen machinery envelope pressure, high-pressure pump water filling to add to crush rock.Solve slungshot and noise, but needed the machinery envelope to press and high-pressure pump water filling pressurization, limited in one's ability.Do not see renewal technology through international online retrieval.
The purpose of water gun crushing method and device invention is to provide a kind of breaking method that slungshot, low noise, explosive consumption are few, can implement that do not have everywhere for solving the broken problem of rock and concrete.
The pressure that water gun crushing method produces when being the explosive charge that utilizes in the water cannon acts on water, will treat brokenly that by water fragmentation opens.Water cannon 1 is made of transmitting tube 3, bore 4, breechblock 2, and detonator hole 5 is arranged in the breechblock 2.The external diameter of the transmitting tube 3 of water cannon 1 can be determined by aperture, big gun hole, and is generally smaller than the aperture; Available being threaded also can otherwise connect between breechblock 2 and the water cannon 1.It is like this that water gun crushing method is implemented: treating brokenly to accomplish fluently big gun hole 7 on the body 6, giving big gun hole 7 fills with water 8.Explosive 10 is packed in the bore 4 of water cannon 1, and breechblock 2 beyond the Great Wall, in the detonator hole 5 that detonator 9 is inserted on the breechblocks 2.Ready water cannon 1 is inserted in the big gun hole 7 for the treatment of brokenly on the body 6, detonating primer 9, explosive 10 blasts produce pressure and act on the water 8, and water 8 will be treated brokenly body 6 fragmentations.After the fragmentation water cannon 1 on the fragment heap being examined back scrub just can be for using next time again.
Water gun crushing method explosive 10 is contained in the bore 4 of water cannon 1, the effect of explosive 10 blasts acts on by aqueous medium to be treated brokenly on the body 6, compare with existing method and not have slungshot, air-shock wave, do not have a strong impact on having on every side, operation is not subjected to the restriction of surrounding environment yet; The water gun crushing method operating principle is different from the shock wave fragmentation of orthodox explosive blasting procedure, and it is to utilize media expansion and fractured rock and concrete can make full use of the structural plane for the treatment of brokenly that body is intrinsic, only needs minimum explosive, so greatly reduce cost; Compare the mechanism that does not need complexity with the Mechanical Method fragmentation; Simple more, reliable with the broken rock device patented technology ratio of high hydraulic pressure.The water gun crushing method invention can be widely used in engineerings such as city dismounting, mining, water power excavation.
Fig. 1 is the structural representation of water cannon.1 is the water cannon main body, the 2nd, can screw thread or the breechblock that is connected with main body of alternate manner, and the 4th, the bore of blasting charge, the 3rd, transmitting tube, the 5th, the detonator hole on the breechblock.
Fig. 2 is the water gun crushing method principle schematic, the 6th, treat brokenly body, and the 7th, the big gun hole, the 8th, water, the 10th, explosive, the 9th, detonator, water cannon 1 is inserted in the big gun hole 7.
Water gun crushing method and device inventive embodiments: at 1.5m
3The rock bulk in bore Φ 40mm, the hole 7 of dark 0.6m, fills with water 8 in the hole 7.Dress 15g explosive 10 is inserted into detonator 9 in the explosive 10 by the detonator hole on the breechblock 2 in the bore 4 of water cannon 1.In ready water cannon 1 patchhole 7, detonating primer 9, explosive 10 blasts are with 6 fragmentations of rock bulk.Broken piece is even, no slungshot, and the report oppressiveness, water cannon 1 is scattered on the fragment heap, does not have and damages and can use again.
Claims (3)
1, water gun crushing method and device are that the energy that utilizes explosive blasting to produce comes fractured rock or concrete, it is characterized in that explosive is contained in the bore of water cannon, and water cannon inserts in the big gun hole, fills with water in the big gun hole, and the explosive in the water cannon is by the cap sensitive that is inserted in the breechblock.
2, water gun crushing method according to claim 1 and device is characterized in that the water cannon that it uses is to be made of transmitting tube, bore, breechblock etc., and available screw thread and other mode connect between breechblock and the water cannon, are provided with the detonator hole in the breechblock.
3, water gun crushing method according to claim 1 and 2 and device is characterized in that injecting in the big gun hole water.
