That is, when the first air nozzle 24 of the injection nozzle member 20 supplies air of about 10 PSI to the closed space, if there is no crack in the sewer pipe, the check sensor 30 feeds back 10 PSI of air pressure All of the supplied air is discharged, and the flow goes to the search step S100 again, in which the pressure lower than 10 PSI of the supplied air is fed back so that the cracking state of the sewer pipe can be known.

The air data supplied from the first air nozzle 24 of the injection nozzle member 20 is also transferred and stored in the second data provided in the control device 64 of the control means 60 and the crack state is checked The check data is stored in the check data unit provided in the control unit (64) of the control means (60) so that the state of the sewer pipe before maintenance can be known.

The control device 64 of the control means 60 controls the supply device 64 of the control means 60 in the remedial solution injection step S500 according to the data of the crack state of the sewage pipe checked in the checking step S400, And the repair liquid is sprayed through the maintenance liquid nozzle 24 of the injection nozzle member 20 to repair the crack portion of the sewage pipe. In this case, the injection nozzle member 20 of the check step S400, (S600) for checking the air pressure by supplying a certain amount of air again to the space where the first air nozzle 24 of the first air nozzle 20 is closed to check the maintenance state of the sewer pipe, It is possible to accurately confirm the maintenance status of the sewer pipe by reading whether to move or move to the next step.

The checked data checked in the second check step (S600) can be transferred to the check data unit provided in the control unit (64) of the control means (60) to easily confirm completion of the sewer repair.

The packer member 10 is transferred to the front and rear ends so that the inner diameter of the sewer pipe is maintained to be the same as the inner diameter of the sewer pipe after the completion of maintenance in the second check step S600, And a cutter step (S700) for cutting off the remedied liquid flowing out into the sewage pipe by the cutter member (40) provided at the center of the sewer pipe.

As described above, the air and the remedial fluid data supplied to the jet nozzle member 20 are supplied with a predetermined amount according to the data stored in the control device 64 of the control means 60, by sensing the number of rotations of the pumping motor.

As described above, according to the repair method of the present invention, it is possible to easily check the state of cracks generated in the sewer pipe, check the state of supplying and repairing the repair fluid according to the degree of cracking, The exposed maintenance fluid is cut to form the same inner diameter and the same inner diameter as the repair inner surface, so that the flow of the flow rate can be smoothly performed.

Thus, when the repair liquid is cut by the cutter member 40, the outer circumferential surface of the repair part, which is cracked in the sewer pipe, can be easily restricted from moving forward and backward by the expanding tube 16 of the packer member 10 12, the maintenance state is completed by the second check step (S600), and the tube 16, on which both side surfaces of the packer member expand, discharges a predetermined amount of air in accordance with the inner diameter of the sewer pipe, And an air discharging step (S800) for discharging the air of the tube (16) expanded at the outer periphery of the packer member (10) so that the air (10) can move.

That is, the air in the closed space is discharged by discharging the air of the expanded tube 16 in the portion of the tube 16 on both sides of the packer member 10 where the cutter member 40 does not act, And the tube 16 in which both sides of the packer member 10 are expanded on the basis of the data of the third data provided in the control device 64 of the control means 60 in the closing step S300 So that the packer member can be more easily moved.

Also, since the maintenance fluid exposed on the back surface of the repair is cut to form the same inner diameter and the same inner diameter, the flow of the flow rate can be smoothly performed, and movement and cutter can be performed at the same time, .
