Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise.

Also, the terms of " part ", "... module" in the description mean units for processing at least one function or operation, which may be implemented by hardware or software or a combination of hardware and software.

Hereinafter, a water tube device for controlling blasting dust according to an embodiment of the present invention and a blasting dust control method using the same will be described in detail with reference to the drawings.

Here, blasting dust control using gunpowder is used for blasting dust control. In a blasting spray, the atomization is a liquid - gas abnormal flow. The shock wave due to the explosion of the explosive gas and the gas expansion of the high pressure cause the water as the medium to have a very high initial velocity and the water ejected into the air comes into contact with the air layer to cause the formation of the liquid droplet and the droplet.

When the droplet size is larger than the dust particle size in the dust control using water, the dust flows around the air stream. If the size of the droplet size is equal to or smaller than the particle size of the dust, the dust flows in the air stream around the droplet and is adsorbed in the droplet. Since the fine dust generated at the blasting demolition site is more diffusive than the coarse dust, it is necessary to spray the particle size of the water in the form of a bath to control it.

Accordingly, the water tube device for controlling blasting dust according to the embodiment of the present invention can spray the water filled in the water tube in which the explosion-proof scattering wire is embedded in the form of a mist to reduce the coarse dust blocking and the fine dust.

At this time, an appropriate droplet diameter for reducing the coarse dust blocking and the fine dust in the range of 10 to 2.5 mu m can be expressed according to the detonation line width.

In addition, it is possible to arrange continuity and to facilitate installation inside and outside of the structure to be blasted.

8 is a front sectional view of the water tube 101, and has a polygonal shape.

The above-described water tube apparatus 100 for controlling the blasting dust combines a detoxification line 107 inside the water tube 101 to control the blasting dust.

Here, the water tube 101 is easy to purchase on the market regardless of the material, and can be used as a product that can withstand water pressure.

The water tube 101 is an elongated tube having a diameter of 150 mm or more, and is provided with a decay line 107 therein, and water is injected. The water injected into the water tube 101 generates high-speed fluid diffusion due to the explosion width of the explosive. Spray particles, which are generated extensively in the form of a slurry through this fluid diffusion, adsorb the blasting dust. In addition, depending on the diameter and the number of the tubes, explosives may be dispersed in the interior along with the detonation lines 107.

As shown in FIG. 9, the droplet inserting devices 103 and 105 coupled to both ends of the water tube 101 may have a cap shape. At this time, the detox line 107 can be installed at the lower end or the center of the water tube 101.

And water injection and internal air discharge are easy after the detoxification line 107 is installed.

Here, when the diameter of the water tube 101 is set to 150 to 300 mm as a reference, and the decay line 107 is set at 20 g / m 2, the spraying speed of the water blasting dust control apparatus 100 is about 120 m / s And the spreading height or duration of the spray can be optimized. At this time, the spray height diffuses to an average of 20 or more.

Also. It is possible to develop a spray having a droplet diameter of 0.2 mm or less for smooth dust adsorption.

In the case of the spray duration, the maximum duration is about 3 seconds, the spraying time is about 1 second, and the horizontal spraying distance is about 4 to 6 m. Therefore, The time difference can be set to 1,000 to 1,500 ms in consideration of the maximum spray time, and the hot interval can be set to about 5 m. When installing on the ground, care should be taken to prevent unevenness of the ground in order to prevent the flow of the detonation position of the detonation line (107).

As shown in FIG. 9, the insulated wire inserting apparatuses 103 and 105 may be made of a PVC material capable of withstanding shock wave at a water pressure and a separation distance. And a cap with a screw thread which can be fastened to the cylindrical body of the water tube 101. [

The water tube 101 is installed on the ground and the detoxification lines 107 are inserted and then the detoxification apparatuses 103 and 105 are coupled to both ends of the installed water tube 101 by a coupling means such as a rubber band.

A detoxification line 107 and a primer holder 107 which are separated from each other by 20 cm or more from the tip of the detonating device 103 or 105 by connecting the priming tube 117 and the detoxifying line 107 prepared when the water tube 101 and the detox line 107 are coupled, 115 and the detonating wire 107 are inserted and fixed. At this time, each line of the primer is taken out through the primer outlet 119, and the outlet 119 is sealed to prevent water from leaking out. The gas inserting apparatuses 103 and 105 discharge the internal air through the air outlet 115 on the rear side without causing water injection and leakage, and simultaneously inject water into the water tube, Can be maximized.

In order to prevent rapid scattering of the plastic of the apparatus due to the detonation of the detonator, it is possible to prevent scattering of the detonator when the detonator is spaced more than 20 cm from the end of the apparatus 100.

The water injection valve 107 of the first wire rope inserting apparatus 103 when the first wire rope inserting apparatus 103 and the water tube 101 are combined serves to fill the water inside the water tube 101. And the air discharge valve 115 is opened at the same time as the water injection and discharges the air inside when the second gas ray inserting device 105 and the water tube 101 are coupled. After the water injection is completed, both valves are closed.

The embodiments of the present invention described above are not implemented only by the apparatus and method, but may be implemented through a program for realizing the function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
