Of course, sleeve chamfers may be provided at outer edges of both end surfaces of the connection sleeve. Because the inner wall surface of the underground pipeline may have defects such as breakage and bulge, the inner wall surface of the underground pipeline is uneven, the connecting sleeve is directly contacted with the bottom of the underground pipeline, the connecting sleeve can be prevented from being clamped in the underground pipeline through sleeve chamfering, and meanwhile, the resistance of the liner tube in the pushing process is reduced.

The second annular projection is provided with a second annular inner cavity 2.9. The first annular protrusions are located between the two second annular protrusions, and the protrusion height of the first annular protrusions is larger than that of the second annular protrusions. The second annular inner cavities in the two second annular protrusions are respectively connected with the first annular inner cavity through connecting channels 2.10. The connecting channel is arranged in the annular rubber sealing layer. The end surfaces of the two lining pipes in the connecting sleeve are propped against the outer surface of the first annular bulge, so that the end surfaces of the two lining pipes in the connecting sleeve are connected in a sealing way through the first annular bulge; and the end surfaces of the two lining pipes positioned in the connecting sleeve extrude the first annular inner cavity in the first annular bulge, so that gas in the first annular inner cavity enters the second annular inner cavities in the two second annular bulges through the connecting channel, and the second annular bulges bulge towards the outer wall of the lining pipe and are clung to the outer wall of the lining pipe. In this way, under the condition that the assembly of the lining pipe structure for repairing the underground pipeline in the underground pipeline is not affected (namely, one end of one lining pipe of two lining pipes which are adjacently distributed is inserted into the connecting sleeve from one end of the connecting sleeve, one end of the other lining pipe is inserted into the connecting sleeve from the other end of the connecting sleeve), the first annular inner cavity in the first annular bulge is extruded through the end surfaces of the two lining pipes which are adjacently distributed, so that the end surfaces of the two lining pipes positioned in the connecting sleeve are in sealed connection through the first annular bulge; simultaneously, make the gas in the first annular inner chamber get into the second annular inner chamber in the two second annular protruding through the connecting channel to make the second annular protruding towards interior bushing pipe outer wall direction swell and hug closely on interior bushing pipe outer wall, thereby form and form three reliable seal structure between two adjacent lining pipes that distribute, effectively improve the sealed effect between the lining pipe.
Further, as shown in fig. 5, the outer edges of both ends of the inner liner are provided with liner chamfers 1.3. The first annular projection abuts against the chamfer of the liner. Therefore, on one hand, the short-circuit area between the first annular bulge and the inner liner tube can be increased, and the sealing effect between the end face of the inner liner tube and the first annular bulge is improved; more importantly, in the process of extruding the first annular bulge, the liner chamfer angles of two adjacent liner pipes extrude the first annular bulge towards the outer side of the liner pipe, so that gas in the first annular inner cavity enters the second annular inner cavities in the two second annular bulges through the connecting channel, and the second annular bulges bulge towards the outer wall of the liner pipe and are clung to the outer wall of the liner pipe; the problem that the second annular bulge cannot bulge towards the outer wall of the inner liner tube due to the fact that the first annular bulge is extruded into the cavity of the inner liner tube by the end faces of the liner tubes of two adjacent inner liner tubes is avoided.
