The present invention relates to a repair method and repair materials dedicated to the pipe joint step difference, it is possible to precise installation and construction in which the gap between the joints between the pipe line is not generated, the gap is hardly generated.

In general, in the repairing method of joints buried underground, various abnormal parts that may cause leakage, such as gaps or gaps in the joints, are made of reinforcing materials impregnated with polyurethane-based adhesive resin. There is a method of forming an index reinforcing layer on the outside by compressing to form an FRP layer therein or by injecting a polyurethane index agent into the sewer pipe outer wall. It can be installed in medium and large diameters, can be installed in the joints of connecting pipes, and can be extended in repair width. After completion of the construction, it is possible to evaluate the repair result by conducting a partial water test immediately. In case of repairing with stainless material, there is less diameter reduction of sewage pipe, excellent strength and fast construction speed. Due to the stainless steel characteristics, it was impossible to repair the joints due to the step difference of the pipes. However, in this design, the joints between the pipes could be repaired by utilizing the wrinkle characteristics of the predetermined width of the outer peripheral surface of the material.

There is no fear of being separated from the repair position by the fastening device even at high pressure cleaning, and it is possible to extend the repair width by the repair machine due to the gap between wrinkles, and the medium and large diameter construction is possible. There is no fear of water pollution because it is not chemically treated, and the creases of predetermined width on the outer circumferential surface are press-molded by a round roller which rotates 360 degrees and vertically moves from the center to facilitate the flow of sewage.

Accordingly, the present invention is to provide a method and materials to more efficiently construct the joint repair, which was impossible to repair in the stainless steel material during the non-excavation repair to the sewer pipe.

It is a feature of the technical configuration that the crease is folded and adhered to the joint.

In this case, the corrugated bone of the repair material is deformed to fit the gap between the joints or the pipe. The technical features are that the corrugated bone formed in advance by the rotation and vertical horizontal movement is pressed on the wall, and the inner wrinkles are unrolled by the round roller, and the external threaded wrinkles are unfolded and attached to the wall surface of the joint at the same time. do.

The curved lines of the general shape projecting on the outer side may cause the curved surface not to be alive when the roller is pressed, and the curved surface itself may be bent. It is characterized by technical configuration of repair materials for stepped vehicles.

The supporting means of the repairing material is fastened to the belt-type fastening part of the repairing material at the same time, and the locking protrusions and the locking holes are fastened at the same time, so that both sides have sufficient restraint force except the wrinkles, and are wound into a cylindrical shape and inserted into the pipeline in a contracted state and then expanded. . In the repair material for the pipe joints, which is installed in close contact with the inner wall of the pipe connection, the repairing material has a predetermined elastic force to be released to its original state when it is wound in a cylindrical shape, and overlaps with the other end to overlap with the other end. And a locking protrusion which is joined to the outer side of the other end of the repairing material and is caught by the locking ball so as not to be contracted after the repairing material is expanded.

The locking ball of the fastening portion may be formed in a plurality at regular intervals along the longitudinal direction of the repair material and the locking projection 126 may be formed in a plurality at a predetermined interval to match the locking ball 115. have.

In addition, the portion of the other end of the sleeve is formed to be partially bent so as to protrude to the outside of the engaging portion 126 is caught.

In addition, the locking protrusion 126 may be bent in the outer direction after being partially cut in a trapezoidal shape, it may be characterized in that it is formed inclined in a direction facing one end of the sleeve.

In addition, the left and right both ends of the sleeve may be formed to be inclined outwardly to a predetermined degree so that the diameter of the left and right both ends in the wound state is wider.

In addition, the sleeve may be characterized in that a plurality of corrugated bone is formed in a predetermined width along the outer circumferential surface.

In addition, the sleeve may be characterized in that the circular and threaded pleats are formed in a predetermined width along the outer peripheral surface.

In addition, due to the support means, the repair material is fixed, and the wrinkles can be extended to fit the inner wall of the joint connection gap can be a feature of the technical configuration.

In addition, the sleeve may be characterized in that it is not necessary to be wrinkled by the roller when the gap between the pipes and the size of the step is not large as the repair material for the joint step difference.

In addition, the outer surface of the sleeve may be characterized in that the sealing material for sealing of rubber material is attached.

Hereinafter, embodiments of the present invention as described above will be described in detail with reference to the accompanying drawings.

Rubbing the inner circumferential surface of the corrugated bones (A) protruding outwardly to fill the step portion between the pipe. As described above, the repair material of the present invention is to be smoothly installed even in the stepped section by connecting the pipelines by the formation of the corrugated bone (A) (see Fig. 6).

The corrugated bone (A) may be formed in a wider width in the repair material (S) and may be formed in the entire repair material (S).

The present invention has an effect that the inner surface of the sleeve is smoothly formed as a repair material for the pipe joint step difference, and does not interfere with the flow of sewage installed in the pipe.

In addition, since the present invention does not cause leakage through the cut-out machining site for the same reason as above, it is ensured of reliable exponentialness after being installed in the pipeline.

In addition, the present invention has the effect of having a sufficient restraining force by being fastened at the same time a plurality of engaging projections and engaging holes of the fastening portion of the front end and the rear end when expanding the repair device.

In addition, the present invention can fill the step between the pipelines by the wrinkles formed on the outer surface of the sleeve can be easily installed and repaired at the site where the two joints connected to the upper and lower sides and shifted.

In addition, the present invention is a 360-degree rotation and vertical horizontal movement from the center by placing a screw-type pleat whose sequential changes in general curve wrinkles and sizes in the repairing material to efficiently repair the misaligned parts of the inner joint Press-molded with a round roller, the corrugations are folded sequentially by the pressure of the round roller and attached to the wall of the joint. When the joint step is not severe, it is not necessary to compress the wrinkles.

In addition, the present invention can be different in the circular size and the angle of the material by inflating the non-wrinkle portion with a repair material that can vary the expansion size in the front end and the rear end.

In addition, the present invention has the advantage that the repair material made of stainless steel is strong corrosion resistance, does not rust and corrosion to chemicals. In addition, the thickness of the steel plate does not hinder the flow of water because the pipe is not thickened in repairing the pipe joints.
