The inner diameter of the connecting sleeve is larger than the outer diameter of the adapting pipe and the supporting pipe, the connecting sleeve sequentially comprises a first section body and a second section body from the adapting pipe to the supporting pipe, one end of the first section body is welded with the second section body, one end of the first section body, which is far away from the second section body, is integrally connected with a first short pipe, the inner diameter and the outer diameter of the first short pipe are both smaller than those of the first section body, and one end of the first short pipe, which is far away from the first section body, is welded with the outer side wall of the adapting pipe. A second short pipe is integrally connected to one end of the second section body far away from the first section body, the inner diameter and the outer diameter of the second short pipe are smaller than those of the second section body, and one end of the second short pipe far away from the second section body is welded with the outer side wall of the supporting pipe; and a glue injection hole is formed in the side wall of the second section body, and a glue injection plug is arranged on the glue injection hole.
One end of the bearing pipe close to the supporting pipe is trumpet-shaped, and one end of the lining pipe is tightly pressed between the bell mouth of the bearing pipe and the supporting pipe.
By adopting the scheme, the method has the following advantages:
because the utility model discloses a both ends of the stay tube of small-bore lining pipe joint all have the adapter tube, have the adapter sleeve between the lateral wall of adapter tube and the lateral wall of stay tube, all have the lining pipe in the adapter tube, the one end of lining pipe is located between the looks proximal end of adapter tube and stay tube, and this end of lining pipe is connected with the adapter tube and the stay tube is fixed sealed form, the other end of lining pipe passes the adapter tube one end of keeping away from the stay tube, stretches out outside. During the use, will need the old pipeline section of reforming transform to be a segment, will the utility model discloses a during two old pipeline segments that link to each other are installed to small-bore lining pipe joint, make the outer end of two adapter pipes of small-bore lining pipe joint respectively with the mouth of pipe welding of two old pipeline segments together, make the adjacent end of two adjacent small-bore lining pipe joints share a lining pipe to make the lining pipe run through need reform transform old pipeline can. The small-caliber liner pipe joint is adopted to reconstruct the old pipeline, the whole old pipeline does not need to be replaced, the reconstruction time is short, and the reconstruction cost is greatly reduced.
