Description

Technical Field

[0001] The utility model relates to the technical field of pipeline repair, in particular to an inner lining structure for pipeline repair. Background Art

[0002] With the continuous advancement of science and technology, it is now possible to repair underground pipelines without excavation after they are broken. At present, a liner corresponding to the pipeline will be set to repair the pipeline. The liner is divided into tubular and spiral shapes. For example, the utility model patent with application number CN202123454492.6 discloses a flexible liner for pipeline repair, which belongs to the field of pipeline repair technology, including a main body, a plurality of groups of T-shaped positioning ribs are arranged at intervals along the width direction of the main body, convex buckles and buckle grooves matching the convex buckles are respectively arranged at both ends of the width direction of the main body, and a positioning diagonal brace inclined outward is arranged on the side of the buckle groove away from the main body. When the convex buckle is buckled with the buckle groove, the end of the positioning diagonal brace abuts against the bend on the inner side of the T-shaped positioning rib. When repairing, the flexible lining is driven by the laying equipment to spirally coil in the original pipe and push the convex buckle into the buckle groove. When the convex buckle is buckled into the buckle groove, the positioning diagonal brace pushes the T-shaped positioning rib adjacent to the convex buckle to the side away from the convex buckle, and buckles and abuts against the bend on the inner side of the T-shaped positioning rib. Compared with the prior art, the structural strength of the spirally coiled and buckled flexible liner is further improved through the cooperation of the T-shaped positioning rib and the positioning diagonal brace, preventing the convex buckle from falling out of the buckle groove under the action of external force.

[0003] Although the above patent further improves the structural strength of the spirally wound buckled flexible liner through sealing and biting structures, a complex sealing structure is set at the biting point. Secondly, the above patent lacks further elastic support structure. The sealing structure will increase friction during the biting process, increase the resistance to shrinkage and expansion of the liner, and cannot ensure close contact between the liner and the inner wall of the pipe. In addition, the inner wall of the liner is smooth. One is that the water flow will impact the pressing position of the liner, and the liner is prone to water seepage after a period of time. Another is that it is inconvenient to flexibly shrink inside the pipe during installation. The above defects reduce the practicality and operational flexibility of the spiral liner.
