| titleOfInvention | Pipe rehabilitation method and device using dry ice |
| abstract | The present invention relates to a pipe rehabilitation method and apparatus, and more particularly, by spraying dry ice and nitrogen at the same time to cause cracks in the scale layer to expand and remove the foreign matter can be quickly removed It relates to a pipe rehabilitation method and apparatus.n n n In the pipeline regeneration method of the present invention, in the pipeline regeneration method using dry ice, the skin layer peeling step of removing the scale layer skin of the inner peripheral surface of the pipeline; A scale removing step including a crack generation process of rapidly cooling the sprayed dry ice pellets so as to collide with the scale layer and generating a crack, and an expansion process of expanding and removing the scale layer while the dry ice pellets sublimate in the cracks; A waste removing step of removing waste generated through the scale removing step; A film layer forming step of forming a film layer on the inner circumferential surface from which the scale layer is removed; And it is characterized in that it comprises a drying step of drying the coating layer.n n n Thus, by supplying low-temperature nitrogen gas to the dry ice pellets compressed by compressed air to further cure the dry ice pellets, unlike other blasting media, the hardness of the dry ice, which is relatively low in hardness, is strengthened so that the impact amount is made larger to the scale layer. After the crack is generated, by using the expansion action of the sublimation of the dry ice to peel off, remove the foreign matter, the removal efficiency of the foreign matter can be improved than simply spraying the dry ice and the working time can be shortened. In addition, since dry ice (C02) and nitrogen (N2) are used to remove the scale layer fixed to the pipeline, there is an advantage that the inside of the pipeline is not contaminated secondarily. And, the main body which can remove the coal tar enamel layer or the combustible foreign matter remaining on the inner wall surface of the old pipeline more quickly and easily by using the skin layer removal device and the heating device, and can freely move the inside of the deformed or curved pipeline. The work device can perform the rehabilitation work unattended while observing the image captured by the camera from the outside, thereby improving workability and safety. |
