To a blasting truck that moves the forming apparatus unattended.

Generally, water pipes, dirt, gas and the like are supplied to the inner wall of the pipe when the pipe is aged and used for a long period after installation, such as water pipe of middle or large diameter for supplying tap water, small diameter water pipe, sewage pipe for discharging sewage, Various kinds of foreign substances contained in the fluid of the fluid are sludged and when the conduit is made of a metallic material, the inner surface of the conduit is oxidized to generate rust, and these are solidified to form a scale layer.

Since the sludge or scale layer formed by the deposition of rust and foreign matter formed on the inner surface of the fluid channel is gradually thickened and solidified with the lapse of time, it obstructs the smooth flow of the fluid, And the scale layer attached to the pipeline melts into the fluid, causing the fluid to be contaminated.

Particularly, there has been reported a case where the operation of the reactor due to the inflow of foreign matter is stopped in the nuclear water seawater piping.

Therefore, in order to solve such a problem, it is necessary to clean the pipe line, draw scrapers accumulated in the pipe line by pulling separate equipment into the pipe line, and use a scrapers method and a water jetting method using high- (Water jet) method, and a poly-pig construction method in which the scale layer on the inner surface of the pipe is removed by rushing the poly pigs by high pressure have been developed and applied in the field.

Such prior arts include Registered Patent No. 10-0956291 filed and filed with the Korean Intellectual Property Office, Application No. 10-2005-0090648, and the like.

However, in the prior art, there is a fear that the workers may be injured by the suction of the fine dust due to the direct injection by the person, and the inside of the pipe is cleaned, and the inside of the pipes of various sizes can not be cleaned. And it is used only for simple cleaning.

In order to solve the above problems, the present applicant has proposed "Pipe Cleaning Cleaning Truck (Registration Number: 10-1236341)" which cleans the inner wall surface of the piping by using high-pressure water.

However, the applicant has developed a "mobile track for cleaning pipes (registration number: 10-1236341)" which is a device for cleaning a wall surface inside a pipe by water pressure using liquid water, and is very thick as water pressure is left for a long time There is a problem that the removal efficiency of the sludge or scale layer and the sputum rust is somewhat difficult and the cleaning efficiency of the channel is somewhat low.

When the pipe is cleaned, a painting operation is usually performed by applying a coating material to the inside of the pipe wall. Generally, when the inner wall surface of the pipe is cleaned by water pressure, the roughness of the wall surface is somewhat lowered, The adhesive force of the applied coating material is somewhat low, causing a problem that the coating material is easily peeled off from the wall surface.

4E, when air flows into the storage tank 23, air pressure is generated therein, so that the metal powder stored in the storage tank 23 flows into the second guide pipe 25 At this time, a certain amount of metal powder flows through the feed pipe 24 through the feeder 26, and a certain amount of metal powder flows through the feed pipe 24 ,

As shown in FIG. 4F, when air flows into the conveying pipe 24, the metal powder flowing into the conveying pipe 24 through the second guide pipe 25 is forced through the wind of the air, The metal powder thus transferred is flowed through the wind power to the injection pipe of the injection part 13 and finally discharged to the first guide pipe of the blasted bogie 10, And is strongly jetted to the wall surface inside the channel 1 through the nozzle 13c.

4G, since the injection pipe 13a is continuously rotated together with the injection nozzle 13c by receiving the rotational force from the rotation unit 14, the metal powder sprayed through the injection nozzle 13c So that the sludge and scale layer inside the channel 1 and the rusted rust are effectively removed and cleaned.

At this time, roughness is formed for easily adhering the coating material to the surface of the wall surface of the channel 1 through the metal powder sprayed on the wall surface of the channel 1. The roughness formed is preferably 50 to 100 microns So that the peeling phenomenon of the coating material coated on the inner wall surface of the channel (1) is prevented in advance.
