Traction type pipe repair apparatus and pipe repair method using the same

摘要

The present invention relates to a traction-type pipe repair device and a pipe repair method using the same, and prevents damage to the lining material by minimizing steps or rough inner surfaces caused by damage to the pipe in the process of towing the lining material inside the pipe. A traction-type pipe repair device that allows traction and inserts the protective film while cutting it in the process of inserting the lining material into the inside of the pipe, so that it adheres more closely to the inside of the pipe and hardens, thereby improving repair quality and efficiency. The goal is to provide a pipe repair method using this method. The present invention for achieving the above object is supplied to the inside of the pipe through a lining material supply unit installed on the starting manhole side, and is configured to surround the outside of the film coating material and the film coating material, and a heat source is supplied to the inside of the film coating material. A lining material including a felt that expands and adheres to the inner surface of the pipe and hardens to form a repair material, and a protective film that surrounds the fe A lining material towing unit installed on the arrival manhole side and pulling the lining material toward the arrival manhole through a towing line connected to an end of the lining material; A heat source supply unit connected to the lining material and supplying a heat source to the inside of the lining material so that the lining material expands, attaches to the inner surface of the pipe, and then hardens; A lining material guide part that is installed in the pipe and prevents the lining material towed through the lining material pulling part from being damaged while being towed and allows the lining material to be towed; A protective film cutting unit installed on the outside of the starting manhole to cut the protective film in the process of supplying the lining material into the interior of the pipeline through the starting manhole, thereby allowing only the film coating material and felt to be inserted into the interior of the pipeline. Including; The technical summary is about the towed pipe repair device and the pipe repair method using it.
