Device for repairing sewage pipe and method for repairing sewage pipe using the same}

The present invention relates to a sewer rehabilitation apparatus for inserting and regenerating a fuse in a state in which a defective sewer pipe is not excavated, and a sewer rehabilitation method using the same.

In general, sewage pipes are pipes installed to discharge sewage or wastewater generated in homes, factories, etc., and are usually buried in the ground by setting proper slopes so that sewage and residues continue to flow without accumulation.

Such a sewage pipe is configured to have a strength that can withstand earth pressure or a load of a vehicle. In addition, a sewer pipe, a reinforced concrete pipe, steel pipes, PVC pipes, etc. may be used. It is becoming.

If the sewage pipe is used for a long time, the sewage pipe may be blocked or partially damaged, causing problems in the sewage treatment, so the sewage pipe should be maintained or repaired. Therefore, the sewer pipe is installed in the installation area at regular intervals to form a manhole, through the manhole to check or repair the sewer pipe.

However, if the damage to the pipe is severe, there is a limit to repair through the manhole, so the bad sewer pipe should be replaced with a new sewer pipe. However, the construction to replace the sewage pipes should be dug out the bad sewer pipes buried in the ground and to install a new sewer pipe, so the construction period is significantly longer, and construction costs will increase significantly. In particular, when replacing the sewer pipes buried in downtown, etc., there is a problem that not only impedes traffic, but also causes traffic jams, resulting in considerable inconvenience.

Due to this problem, various methods have been attempted to rehabilitate existing pipelines through manholes without replacing defective sewer pipes.
