In order to solve the problems, the technical scheme provided by the utility model is as follows: a pipeline non-excavation sleeve repairing device comprises a pipeline to be repaired, a sleeve, a groove, an introduction hole, an air bag, a grease injection pipe, a grease injection box, a blower, a blast pipe, a connecting hole and a center column; the central column is positioned in the pipeline to be repaired; an air bag is sleeved on the outer circumferential surface of the central column, a connecting hole is formed in the central column, and the connecting hole is communicated with the air bag; the output of the blower is a blower pipe which is communicated with the connecting hole; the air bag is sleeved with a sleeve; the outer circumferential surface of the sleeve is provided with a groove, and the section of the groove is circular; an introduction hole is arranged in the sleeve and is communicated with the groove; one end of the grease injecting pipe is communicated with the leading-in hole, and the other end is communicated with the grease injecting box;
the fat injection pipe is provided with a valve;
the liquid resin is placed in the fat injection box;
sealing rings are arranged at two ends of the sleeve;
the outer diameter of the sleeve is smaller than the inner diameter of the pipeline to be repaired by 1 millimeter;
the sleeve is made of 316L stainless steel with high plasticity;
the grease injection pipe is a high temperature resistant hose of sufficient length, and the blower pipe is a hose of sufficient length.
The utility model has the beneficial effects that:
1. an air bag is sleeved on the outer circumferential surface of the central column, a sleeve is sleeved on the air bag, and the sleeve is deformed and expanded by inflating the air bag so as to be closely attached to a pipeline to be repaired; the two ends of the sleeve are provided with sealing rings, so that the auxiliary sealing effect can be achieved.
2. The outer circumferential surface on the sleeve is provided with a groove, the section of the groove is circular, resin is injected into the groove, so that the resin fills up the groove and gaps between the sleeve and the pipeline to be repaired, and the problem of poor sealing performance under the condition that the inner wall of the pipeline is uneven is prevented.
In summary, the problem of poor sealing performance after repair when the condition of uneven inside the pipeline occurs can be solved by arranging the sleeve with high plasticity as the lining and arranging the groove on the sleeve and injecting the specific resin into the groove.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
According to the figures 1-3: the utility model provides a pipeline non-excavation casing repairing device, which comprises: comprises a pipeline 1 to be repaired, a sleeve 3, a groove 4, an introduction hole 5, an air bag 6, a grease injection pipe 7, a grease injection box 9, a blower 10, a blower pipe 11, a connecting hole 12 and a central column 13; the central column 13 is positioned in the pipeline 1 to be repaired; the outer circumferential surface of the central column 13 is sleeved with an air bag 6, a connecting hole 12 is arranged in the central column 13, and the connecting hole 12 is communicated with the air bag 6; the blower 10 is outputted as a blower tube 11, and the blower tube 11 communicates with the connection hole 12; the air bag 6 is sleeved with a sleeve 3; a groove 4 is arranged on the outer circumferential surface of the sleeve 3, and the section of the groove 4 is circular; an introduction hole 5 is arranged in the sleeve 3, and the introduction hole 5 is communicated with the groove 4; one end of the grease injecting pipe 7 is communicated with the leading-in hole 5, and the other end is communicated with the grease injecting box 9; the grease injection pipe 7 is provided with a valve 8; the liquid resin is placed in the fat injection box 9; sealing rings 2 are arranged at two ends of the sleeve 3; the outer diameter of the sleeve 3 is smaller than the inner diameter of the pipeline 1 to be repaired by 1 millimeter; the sleeve 3 is made of 316L stainless steel with high plasticity; the grease filling pipe 7 is a high temperature resistant hose of sufficient length, and the blower pipe 11 is a hose of sufficient length.
Principles of the utility model
