Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for repairing and repairing a sewer pipe,

More particularly, the present invention relates to a method and an apparatus for repairing an old sewer pipe, and more particularly, it relates to a method for repairing an old sewer pipe without repairing an old sewer pipe, The present invention relates to a method and apparatus for repairing and reinforcing an old sewer pipe, which is developed to reduce the construction time and the consumption of fuel for steam generation.

In the basement where we live, there is a sewer line to treat sewage, which is connected like a spider web and processes various kinds of sewage.

However, the general sewer pipe which is made of concrete is aged with time, and cracks and partial breakage are caused by subsidence of ground, fluctuation of earth pressure on the ground, cracking and breakage due to external load, and the like.

These cracks and partial breakage are caused by pollution of the soil and contamination of the soil due to leakage of wastewater from the sewage pipe. Therefore, it is necessary to take prompt action. In the past, methods of replacing and reinforcing sewage pipes by drilling the ground were mainly used There were many problems due to the time and manpower consumed by the excavation and the noise and vibration generated during the construction in the case of the city and the control of the traffic due to the construction for a long time.

Recently, a non-excavation repair method that does not excavate the perimeter of the buried pipe has been developed. After the tube-shaped reinforcement is pulled into the old pipe, air pressure is applied to the inner surface of the reinforcement to expand the pipe in the outer diameter direction, A method in which a reinforcing material is drawn into an aged pipe line while the reinforcing material is brought into contact with the inner wall surface of the pipe while the reinforcing material is reversely expanded by pneumatic pressure after winding a tube type reinforcing material to the reversing device, Is applied to the surface of the substrate to thermally cure the substrate.

That is, since the inner wall surface of the aged pipe is thermally hardened to prevent leakage of the sewage, there is no need for excavation, and quick construction is widely used.

However, the larger the diameter of the sewer pipe, the longer the time required to make the required pressure and the high temperature condition by the supplied steam, the condensed water is generated as the temperature of the supplied steam is lowered and the steam is supplied to the inner wall surface of the sewer pipe So that it is impossible to uniformly and integrally adhere to each other.

In addition, the larger the internal space to be expanded, the longer the operation time of the boiler for generating steam, the more the amount of fuel and water required increases, and the construction time increases.
