CN87207860U - Static detonate tube for skew, transverse and underwater filling hole - Google Patents

Abstract

The utility model discloses a static detonate tube for skew, transverse and underwater filling hole which is a new static detonate apparatus. The utility model is a rod-shaped object, and the static detonate tube for skew, transverse and underwater filling hole is made by arranging an expansion agent which can generate the chemical reaction with water and the expansive action in a barrel-type bag-shaped object, and fastening the bag port with a rope. Therefore, the underwater static detonation and the skew, transverse filling hole are convenient. Compared with the pouring method, the utility model is simple and feasible, the time is shortened (dehiscence), and the detonation effect is good.

Description

Static detonate tube for skew, transverse and underwater filling hole

The utility model is a kind of new static blasting equipment.

For the broken and disintegration of rock, concrete construction, the past is all adopted explosive, and its force of explosion is big, and the time is short.Then,, near traffic main artery and the equipment, adopt explosive at dwelling house, both dangerous, can produce huge vibration, noise and slungshot simultaneously, cause public hazards.For the exploitation and the disintegration of valuable stone materials such as granite, marble, white marble, adopt explosive, its lumber recovery is very low.In order to overcome above-mentioned shortcoming, in recent years, studied successfully the static blasting technology.On June 5th, 1981, " disrupting agent of brittle body " that Japan " openly speciallyying permit communique " clear 56-67059 E04G23108 delivers is described, during use, with disrupting agent and water furnishing slurry, water in the boring of the fragile material that is filled in rock or concrete etc., can will be split by broken cubical expansion through a period of time.83 years the 3rd interim disclosed soundless cracking agents of China's " institute of architectural materials science institute periodical " are a kind of powdered substances with high-expansion energy.Water furnishing slurry during use waters and is filled in rock or the concrete boring, can realize the fragmentation of friction, the noiseless of rock, no slungshot, no toxic gas through certain hour.But when reality is used, when by the boring of broken body being level or when being inclined upwardly, slurry cast hand-hole, unusual difficulty just.In addition, when the broken body of quilt of rock or concrete construction is under water, be full of water in the boring,, and, do not reach purpose broken and that disintegrate often because swelling agent runs off seriously because water causes orifice to be difficult to carry out to the diffusion of cracking agent.

The purpose of this utility model provides a kind of being convenient under water and the oblique horizontal static blasting tube used of orifice.

The utility model is achieved in that makes a garden tubular splendid attire thing with the cloth of porous such as cotton etc., pack in it and can produce the swelling agent of expansion with the water chemically reactive, again the splendid attire mouth is tightened, made club, be referred to as the static blasting tube.During use, earlier on by broken body, bored the hole, the static blasting tube has been immersed in the water 2～20 minutes, filled in then in the boring, again with club tampings such as iron staffs.Will be reached effect broken and that disintegrate by spalling by broken body after a while.Also can fill in the static blasting tube more than 1 in boring.The swelling agent that adopts, its main component is calcium oxide, silica, aluminium oxide, iron oxide, magnesia etc.The diameter of made static blasting tube is 7 centimetres of φ 2～φ, and the best is 5 centimetres of φ 3～φ, and length is 15～65 centimetres, and the best is 30 centimetres～50 centimetres.The utility model preparation method is simple, and is easy to use, respond well.

Be described in detail implementing below in conjunction with accompanying drawing.

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is the test block profile.

With reference to Fig. 1, make 3 centimetres of bore φ with cotton, long 35 centimetres cloth bag (1) is filled above-mentioned swelling agent (2) in bag, use cord (3) that sack is tightened then, promptly make a static blasting tube, in order to do contrast test, in kind, make a same static blasting tube again, with 525 ^#Three concrete test blocks of portland cement cast such as Fig. 2,30 centimetres of test block diameter phi, high 40 centimetres, (1) is cement among the figure, and a hole (2) is reserved at the center, its aperture is 3.5 centimetres of φ, dark 30 centimetres, three test block maintenances are after 28 days, will be wherein two place air, divide another name first test block, second test block.The 3rd test block is immersed in the tank, and the aperture up.Carry out the fragmentation experiment of static blasting tube and casting then, just two static blasting tubes are immersed in the water, after spending five minutes, take out and place respectively the second and the 3rd test block, use the iron staff tamping, measure cracking time then, second was ftractureed after 3 hours, and the 3rd test block was ftractureed after 4 hours.Casting is adopted in first test block, is about to swelling agent and adds 28% water, after stirring, is poured into immediately in the hole of test block, through test block cracking after 4 hours.

Annotate: 20 ℃ of 25 ℃ of water temperatures of temperature

Claims (2)

1, static blasting tube is characterized in that swelling agent is contained in the garden tube made from permeable cloth, and sack is tightened by cord.

2, static blasting tube according to claim 1, the diameter that it is characterized in that it are 7 centimetres of φ 2～φ, and length is 15～65 centimetres.
