Description

Single-sided splitting construction Medium / large diameter piping Unscratched internal repair method {omitted}

The present invention relates to a method of repairing a unscratched inner surface of a large-diameter pipeline, and more particularly, to a method of repairing an inner surface of a pipeline including a sewage pipe and a water pipe, .

Generally, in the case of a pipeline including a sewer pipe and a water pipe, it is buried in the underground of a road or the like, so that there is a case where an abnormality occurs in a joint or a specific site due to a buoyancy of the ground, There is a situation in which maintenance is required from the inside.

In the case of repairing or coating only the surface of the pipeline by the lining method including the inner surface of the pipe without the joint of the pipeline, the external pressure acting on the upper ground of the pipeline reduces the external pressure of the pipeline, There is a problem that can cause the problem.

In addition, in the process of repairing the joint by filling the joint without causing the occurrence of an abnormality in the joint portion or the inner surface of the specific portion of the duct, in the case of the upper end portion of the joint portion, It is difficult to remove the filler before the liquid filler material is cured and the maintenance quality is deteriorated and the workability is lowered due to the delay of the construction time.

The present invention has been made in order to solve the problems of the related art, and the present invention has been accomplished in order to solve the problems of the related art, and it has been proposed to divide the joint portion of the channel into the upper end portion and the lower end portion, fill the lower end joint portion of the duct, Filler for the upper part is filled and an arc filling material for the upper part of the joint is made so that an arc filling material for the upper part of the joint is inserted into the upper part of the pipe so that the filling material for the upper part of the joint is prevented from flowing down or falling, So as to improve the maintenance quality and improve the workability.

According to an aspect of the present invention, there is provided a process for cleaning a pipe, comprising the steps of filling a fill material for a lower end portion of a joint to an inner surface of a pipe in the shape of an empty space on a cross- Filling a filling material for an upper end of a joint portion of a liquid phase into a spring filler cylindrical cover after filling the filling material for the lower end of the joint portion to form an arc filling material for the upper end of the joint portion; A step of inserting an arc filling material for the upper end of the joint portion into an upper end joint portion of the pipe after the process, and a process of installing an arc filler material for the upper end portion of the joint portion from the lower portion of the arc- Filling the filler material for the upper part of the joint in the shape of an empty space of the joint part; A step of applying a coating material on the filler material for the upper part of the joint and a filler material for the joint part of the joint part after filling the filler material of the joint part and a step of completing the repair after the step of applying the coating material, It is characterized by an unscratched interior repair method.

As described above, the joint portion of the pipeline is divided into the upper end portion and the lower end portion. The lower end joint portion of the pipeline is filled with the filler material for the lower end portion of the joint, and the filler for the upper end portion of the liquid joint portion is filled in the spring filler cylindrical cover, It is possible to improve the maintenance quality by constructing the filler material so that the filling material for the upper part of the joint part is inserted into the upper end joint part of the joint part and the arc filling material for the upper end part of the joint part is inserted into the ∩ shape, This is a very useful invention for improving the workability.

1 to 7, the present invention relates to a process for cleaning a pipeline 1 using a conventional high-pressure cleaning car, and a process for cleaning the pipeline 1 using a conventional high- , After the step of cleaning the pipe 1, the filler material 5 for the lower part of the joint part up to the inner surface of the pipe 1 in the shape of an empty space on the end face of the lower end joint part 3 of the pipe 1, Filling the upper filler material (9) for the upper part of the joint in the spring-loaded cylindrical cover (7) to fill the filler material (9) for the upper part of the joint part by filling the filler material Shaped filling material 6 for the upper end portion of the joint portion into an upper end joint portion 3 'of the pipe 1 after the step of manufacturing the arc-shaped filler material 6 for the upper end portion of the joint portion, A step for fitting the upper part of the joint part, (11) for the upper part of the joint in the shape of an empty space between the lower part of the arc-shaped filler (6) for the upper part of the joint and the inner surface of the duct (1) A process for filling the filler material 11 for the upper part of the joint part and a coating material for the joint part 5 for the lower part of the joint part and a filler material 11 for the upper part of the joint, 13, 13 ') using one of a conventional brush, a roller or a spray, and a step of finishing the repair after the coating process of the coating material (13, 13'). It is characterized by a channel irrigation internal repair method.

Here, the joints 3 and 3 'including the scour portion of the channel 1 are divided into about half, or the upper portion is divided into the clockwise about 10 to 2 hours and the lower portion is divided into the remaining portions of the upper portion, In consideration of the fact that the filling material 5 for the lower part of the joint part including the conventional repair mortar is not dropped by its own weight in the hollow space section of the lower end joint part 3, It is necessary to fill up the filling material 5 for the lower part of the joint with a general plaster or spray and fill the upper part with the filling material 9 for the upper part of the joint part, Sectional area and circumferential length of the upper end portion of the joint portion 3, 3 'of the conduit 1 so that the filling material 9 in the liquid phase does not fall by its own weight Shaped filling material 6 for the upper part of the joint is filled in the cylindrical spring-loaded cylindrical cover 7 of the joint part to form an arc-shaped filler 6 for the upper part of the joint, Shaped filling material 6 for the upper part of the joint is formed with a hollow space between the lower part of the arc filling material 6 for the upper part of the joint and the inner surface of the channel 1 of the upper joint part 3 ' The filler material 11 for the upper part of the joint part is filled and filled with the filler material 11 for the upper part of the joint part in the shape of a space. In the filler material 5 for the lower part of the joint part and the filler material 11 for the upper part of the joint part, The total length of the partial repair coating material 13 or the pipeline 1 is set to a predetermined width by using a liquid organic or inorganic resin containing a conventional water-soluble epoxy for improving the flow of the effluent including sewage One thing of the whole maintenance coating (13 ') for the phase is adapted to the coating using any one among the conventional brush or roller or spray.

In addition, the spring-loaded cylindrical cover 7 is sewn to the overlapping portion in the longitudinal direction so as to form a cylindrical nonwoven fabric, and a conventional spring 17 is inserted into the cylindrical cover 15 having the overlapping sewing portion 19 So that even if the filling material 9 for the upper part of the joint portion of the liquid phase is filled, the bending performance is excellent and the strength reinforcing effect is excellent.

It is preferable that the filler material 9 for the upper part of the joint part is made of an inorganic material containing common repair mortar and the cylindrical cover 15 is a water permeable material including a conventional nonwoven fabric, It is preferable to use a material having a reinforcing effect as a tensile material.

It should be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
