The present invention relates to a non-drilling pipeline repair device, and more particularly, to form a boundary in the inner middle portion of the tank body, and to form an inverting device to seal the upper one side of the tank body based on the boundary, By supplying air of a certain pressure to the inside of the inverter, the air pushes the water contained in the tank to one side of the boundary portion and forms an air layer inside the tank and the inverter so that the reinforcement tube can be inverted by the air pressure. Simple fabrication and assembly process of reversing device can reduce the cost of the product and at the same time, it is easy to move while minimizing the size of reversing device so that it can be used easily in water and sewage in narrow space. It relates to a repair device and a construction method.

Various water supply and sewage pipes buried in the ground gradually deteriorate with time, causing problems in the water supply pipes due to corrosion, and enormous amount of water leaks, and drinking water is contaminated by the inflow of green water into the pipes. Cracks are generated, and sewage flows out of the pipes and contaminates the living environment such as soil and groundwater.

As described above, in repairing an old buried pipeline in which damage such as cracks are generated, the non-excavated pipeline repair method does not dig ground, and inserts a reinforcement tube into the old buried pipeline in which cracks are generated to form a new composite pipe in the sewer pipe. As a construction method, since road restoration construction is unnecessary, it is a construction method with many advantages in terms of workability, reliability, and economics.

In general, the unexcavated pipeline repairing method is a method of inserting and fixing a reinforcing tube formed of a waterproof coating layer or a film layer and an adhesive resin impregnated felt layer into an old buried pipe.

It can be moved and used, and it can be miniaturized and manufactured, so that the cost of the product can be reduced, and the water and sewage using water check is not excavated because the manufacturing process and assembly process of the water tank main body and the inverting device are simple. To provide pipeline repair equipment.

Still another object of the present invention is that the reinforcement tube is not limited to the inversion length of the reinforcement tube because one end of the reinforcement tube is fixed to the flange of the inverter, the other end is easy to move along a plurality of rollers formed in the tank body and the inverter. It is to provide a water and sewage non-excavated pipeline repair device using a water check that can be continuously inverted for a long time.
