The present invention relates to a pipeline repair propellant, and more particularly, to a repair high pressure propellant for easily performing repair work in an unexcavated high pressure propulsion method when a fault occurs in an underground pipeline.

In general, concrete pipelines buried underground for water and sewage use are often subjected to impact loads due to the high earth pressure or frequent traffic of heavy vehicles, and ground subsidence may occur, resulting in cracks due to these external factors. Will cause defects.

In particular, if a step occurs in the joint between the pipelines because the soil is contaminated by water leakage, it should be repaired quickly.

The non-excavation inner surface repair method is one of the construction methods for repairing the pipeline, and the worker enters the pipeline to repair the leaking part.

However, in the case of a small diameter pipeline that the operator can not enter directly, it is not possible to repair the pipeline by the non-excavated inner surface repair method, in particular, there was a problem that the partial repair work cannot be carried out when the pipeline is completely collapsed.

The present invention has been proposed to improve the above-mentioned conventional problems, and by providing a structure capable of introducing a new pipeline reinforced by one side of the pipeline where defects such as investment are generated by a high-pressure propulsion method, the pipeline repair work is effectively performed.
