The present invention relates to a non-excavated pipe hardening drainage, more specifically, the moisture generated by the hot water or the heat of the steam during the reinforcing tube hardening operation inverted into the inner wall surface of the pipe is accumulated in the curved pipe, At this time, in order to prevent the reinforcement tube located in the accumulated moisture from being in close contact with the inner wall of the pipeline and maintaining the spaced apart state, a drainage device composed of an excel pipe and a discharge valve is installed inside the reinforcement tube to release the accumulated moisture to the outside. The present invention relates to a non-excavated pipe hardening drainage system capable of discharging.

Various water supply and sewage pipes buried in the ground gradually deteriorate with time, causing a large amount of water leakage as corrosion occurs, polluting drinking water by inflow of green water, and polluting the living environment such as contaminating ground water. Is generated.

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 repair 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. An adhesive resin impregnated felt layer is placed inside and a waterproof coating layer is placed on the surface. In one state, the reinforcing tube is inverted into the buried pipe so that the adhesive resin impregnated felt layer, which was the inner surface, is inverted to the surface and adhered to the inner wall of the buried pipe, and the reinforcing tube is coated on the inner wall of the buried pipe.

The non-excavated pipeline repair device uses hydraulic pressure reversal to reverse the reinforcement tube using hydraulic pressure, and pneumatic reversal using air pressure, and hydraulic and pneumatic reversing device using hydraulic pressure and pneumatic pressure. Rotating drum is installed inside the reinforcement tube, the reinforcing tube is wound around the revolving drum, the inverter or reversing device for reversing the reinforcement tube is used separately or used to reverse the reinforcement tube directly from the reversing tank I use it.

On the other hand, in recent years, a repair device for inverting the reinforcement tube using a water check or inverting the reinforcement tube using air pressure has been used. All reversing devices invert the reinforcement tube to closely contact the reinforcement tube to the inner wall of the pipeline. After entering, the reinforcing tube is hardened.

Here, when the reinforcing tube curing operation uses hot water or supplying steam with air pressure to the inside of the reinforcing tube, the reinforcing tube is in close contact with the inner wall of the pipeline by the high temperature heat. Moisture is generated by the heat, which builds up on the bottom of the reinforcement tube.

The reason why water is accumulated inside the reinforcing tube as described above is because the water supply pipe in Korea has a structure that is severely bent due to sedimentation or obstacles in the ground, so it is divided into a pipeline maintaining a horizontal state and a curved pipeline, There is a lot of difficulty in hardening the reinforcement tube because the curved pipe line contains moisture.

The most serious part is the heat generated to heat the reinforcement tube, and the water is generated inside the reinforcement tube. At this time, the moisture is accumulated in the curved pipeline, and the reinforcement tube where the standing moisture is located. Because of blocking the heat, the adhesive resin layer of the reinforcing tube could not be in close contact with the inner wall of the pipeline, so that it was kept in a spaced state, which was difficult to repair.

In addition, there is a problem that acts as a cause of the secondary hole because the best hardening quality cannot be obtained due to the moisture accumulated in the curved pipe.

Due to the problems described above, there is a problem in that the hassle of having to maintain the maintenance from time to time, and if there are many curved portions of the pipe, the hardening operation must be repeated several times.

On the other hand, if the bending is not severe, but the bone is formed in several places in the pipeline because the water is irregularly accumulated, there is a problem in the hardening of the reinforcing tube hard work, thereby causing the sub-holes.

Due to the curved pipe as described above, there is also a problem in that the construction cost of the reinforcing tube is lengthened and the construction cost increases.

The present invention has been made in view of the above-described conventional problems, and its object is that the water generated during the operation of thermosetting the reinforcing tube that is in close contact with the inner wall of the pipe while inverted into the water supply and sewage pipe is accumulated in the curved pipe. Because it cannot transfer heat due to the moisture present, the reinforcing tube can be discharged to the outside using the excel pipe of the drainage device to prevent the reinforcing tube from being separated from the inner wall of the pipeline and causing the secondary hole. It is provided in the excavation pipe hardening drainage system.

Another object of the present invention is to change the properties of the Excel pipe from hard to soft by hot water or steam supplied to the inside of the reinforcing tube to maintain the state in close contact with the curved pipe excel pipe to the moisture The present invention provides a drainage system for hardening an unexcavated pipe that allows water to be easily discharged to the outside through a water inflow hole while a part of the water is locked.

Still another object of the present invention is to open the discharge valve of the excel pipe while the air pressure filled inside the sealed reinforcement tube is discharged to the discharge valve through the front of the excel pipe and the water inlet hole while the water is sucked into the water inlet hole and the discharge valve. The present invention provides a drainage system for hardening an unexcavated pipe that allows the reinforcing tube to be in close contact with the exhaust pipe being heated to apply a heat to the curved pipe.

Still another object of the present invention is to drain the reinforcement tube by using water pressure to prevent water from entering the curved pipe to prevent the smoothing of the reinforcing tube hardening work, the drainage device for curing the unexcavated pipe In providing.

The present invention is a state in which the reinforcement tube is firmly adhered to the inner wall surface of the pipeline while minimizing the time required to harden the reinforcement tube by quickly discharging the moisture accumulated in the curved pipe to the outside without using a separate power or device By maintaining the, to provide a non-excavated pipe hardening drainage to reduce the cost of maintenance.

In order to achieve the object of the present invention, the reinforcing tube impregnated with the adhesive resin inverted into the interior of the pipeline by using water pressure or air pressure, and the repair device for curing the reinforcement tube by unexcavating and repairing the buried pipeline, both ends are open A plurality of excel pipes are formed to extend a predetermined length, and a plurality of water inflow holes penetrating from the inner surface of the excel pipe to the outer surface are formed at a predetermined interval, and a discharge valve is installed at the rear end of the excel pipe. When the opening is characterized in that it comprises a drainage device to discharge the moisture to the outside while sucking the moisture generated during the reinforcing tube curing operation into the inside of the Excel pipe is inserted into the reinforcement tube.

The excel pipe of the present invention uses a material that changes in hard to soft properties by heat applied to harden the reinforcing tube, so that the reinforcing tube is in close contact with the inner wall of the pipe while heat is applied to the curved pipe.

In addition, the air pressure and moisture can be discharged to the outside through the water inlet hole while discharging the sealed air pressure inside the reinforcing tube to the outside.
