FIELD: manufacturing technology.

SUBSTANCE: invention relates to a method for filling a gap with a filling material, where a gap is located between the existing pipe and the facing material provided inside the pipe. Proposed method 1. Method includes the step of attaching an air removal tool, in which the air removal tool is inserted into the air removal hole provided in the upper half of the material of the inner lining, and the front end surface of the air removal tool is brought into contact with the inner surface of the existing pipe. Filling stage in which the filling material is injected under pressure into the gap from the filler neck made through the lower portion of the material of the inner lining, at the same time forcing the air out of the gap through the front end of the air removal tool. Moreover, the tool for air removal includes, at its front end, a section for air removal through which air is discharged.

EFFECT: technical result consists in ensuring that the filling material is prevented from entering the tool for removing air through its opening until the air is completely removed from the gap and in the uniform filling of the gap with filling material.
