摘要
A water supply and drainage non-digging pipe repairing device using a water checking operation, and a method thereof are provided to cut down a cost of a product by simplifying manufacturing and assembling processes of a shifter and to be used simply at a water supply and drainage in a narrow space. In a water supply and drainage non-digging pipe repairing device, a roller(32) is fixed at one side of an upper part for a water tank(22) of a guide member. The roller is fixed to an end portion of a shifter(21) positioned at an opposite side. The roller is formed at the end portion of a fixing shaft(31) positioned at one side of a lower part of a boundary unit(12) and inclined and extended to the lower part at a predetermined angle. A reinforcing support(31a) is formed at one side of the fixing shaft to support the fixing shaft. A method thereof includes a step of moving a reinforcing tube forward by air pressure and entering the reinforcing tube into a water supply and drainage, by forming an air layer at a regular space of an inside for a water tank and a shifter by pushing water formed at the lower part of the shifter, to one side by compressed air supplied from a compressor by powering a reinforcing tube shifting system formed at one side of the shifter.
