Description

[0001] Blast Apparatus for Regenerating a Superannuated Pipe [

More particularly, the present invention relates to a blasting apparatus for blasting a plurality of blast apparatuses having different functions and requiring a large capacity to be coupled to the surface treatment means by a waste tube equipped with a multiple blast gun, The present invention is not limited thereto. That is, the total height can be reduced by constituting independent equipment in which the bogies are separated according to the functions, instead of the integrated equipment using bogies of the bogies. will be.

Generally, casting pipes, steel pipes, synthetic pipes, and concrete pipes are used for conveying fluid such as a water pipe, a sewer pipe, an oil pipeline, and a gas pipe.

Among them, a large pipe mainly uses a cast iron pipe or a steel pipe. When a cast iron pipe or a steel pipe is used for a long time, it is aged due to fluid passing through the inside or other foreign matter.

In particular, in the case of a water pipe composed of a cast iron pipe or a steel pipe, the inside of the water pipe is prevented from being oxidized for safer drinking water supply. However, when the pipe is used for a long time, the coating portion inside the pipe is corroded or peeled.

As a way to solve this problem, there is a method to replace the whole pipeline, but the excavation work for replacing the entire pipeline causes traffic congestion, and it takes a lot of time and cost to replace the pipeline, As a result, the economic loss and the life span are shortened. Therefore, the non-excavation rehabilitation methods that are improved while the pipeline is left are being applied.

Prior art related to the conventional unscrewed shed tube rehabilitation method is as follows: a coating film removing device, a blasting device, and a painting equipment are mounted on the upper part of a moving sled moving inside the shed tube to remove the coating film on the inner surface of the shed tube, And a painting operation was carried out to regenerate the duct.

At this time, the work of forming the roughness on the inner surface of the wastewater before painting by using the blasting equipment is a very important task that affects the success or failure of the painting.

Conventional blasting equipment generally projects a grinding material onto the inner surface of a wastewater tube while rotating and synchronizing with the inner surface of a wastewater tube made of a circular pipe and then separates the abrasive material and foreign materials or separates the recovered abrasive material from the foreign material, .

The blasting equipment includes a blasting gun installed at a tip end to directly contact an inner surface of a waste pipe to project an abrasive material, and a blasting gun coupled to the blasting gun to perform a projecting and collecting operation of the abrasive material, And a blasting device in which the tank and the abrasive recycling storage tank are formed by integral equipment.

Since the conventional blast apparatus is integrally mounted on a single moving truck, when the blast gun is mounted in a plurality, the overall size of the truck is increased. In addition, The overall weight of the stator is increased and the amount of power required to move the stator increases.

In addition, in the case of the abrasive-supplying pressure storage tank and the abrasive-material storage tank constituting the blast apparatus, since the abrasive recycling storage tank is generally disposed on the upper part of the abrasive supply pressure tank, And it can be applied not only to the pipeline of a certain section from the dam caused by the water supply but also to the occurrence of the bottleneck in the process of supplying the abrasive from the upper part to the lower part, However, there was a problem that equipment failure occurred.

Further, even if the abrasive material is insufficient in the pressure tank for supplying abrasives, there is a problem in that continuity of work is deteriorated at the work site since it has to be checked manually.

Accordingly, it is possible to reduce the size of the blast device mounted on the bogie that can be moved from the inner side of the throne pipe, to increase the working efficiency, to prevent the equipment failure, and to increase the continuity of the work. There is a desperate need for technology regarding the device.
