Description

TURNING INSIDE OUT REPAIRING DEVICE OF WATER PIPE BY NON-DIGGING USING NULTI-FUNCTION SAFETY HIGH PRESSURE HOSE AND METHOD OF CONSTRUCTION THEREOF}

The present invention relates to a reversal repair apparatus for a non-excavated water and sewage pipe using a multifunctional safety high pressure hose, and a repair method thereof. More specifically, the rapid extension by expansion of the reinforcement tube is secured through a safety high pressure hose built into the reinforcement tube. It is possible to prevent safety accidents in advance, and also to supply steam and compressed air through the safety high pressure hose, and to drain the water to promote expansion and curing of the reinforcement tube. Is a non-excavated water and sewage pipe using a multifunctional safety high pressure hose that can induce all the problems caused by the reinforcing tube being pushed, damaging the tube gradient, or not properly cured at the part by inducing discharge into the through hole formed in the safety high pressure hose. Reversal repair device and its repair method.

Various water supply and sewage pipes buried in the ground gradually deteriorate with time, and in the case of water supply pipes, there is a problem in that a large amount of water leaks due to corrosion, and drinking water is contaminated by the rust that flows into the pipes. In this case, cracks are generated, and sewage flows out of the pipes and contaminates the living environment such as soil and groundwater.

In repairing the old buried pipelines in which the damage such as cracks occurred, the non-excavated pipeline repairing device and method do not dig the ground, and insert a reinforcement tube into the old buried pipeline where the cracks are generated to form a new composite pipe in the sewer pipe. As a road construction method, there is no need for road repair construction, and thus, it is a construction method having many advantages in terms of workability, reliability, and economics.

In general, the unexcavated pipeline repairing and construction 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. The reinforcement tube is inverted and inserted into the buried pipe in the surface state, and the inner surface of the buried pipe is overlaid with the adhesive resin impregnated felt layer reversed to the surface to be bonded to the inner wall of the buried pipe.

Above all, the method of hardening the reinforcement tube by hot water heat after inserting the hydraulic reversal, which takes a long time to cure, may cause the flooding of domestic sewage, and the extension of the tube on the end portion of the inclined pipe increases, so that the reinforcement tube is small and reinforced. The problem of tube thickness unevenness arises.

In addition, the method of hardening by steam heat after reversal of pneumatic pressure has no self-weight compared with water pressure, which reduces the ability to exclude sewage in the pipeline, which leads to uncured occurrence at the lower end of the pipe. There was a problem that occurred.

On the other hand, the two curing methods described above are not applicable to the water and sewage pipes of the narrow space because the size of the inverting device becomes large, and the manufacturing process and assembly process for manufacturing the inverting device are complicated, and most of the inversion is also in use. In the process of reversing the reinforcing tube wound inside the device, a large amount of air pressure must be continuously supplied for a long time, and the disadvantages that the hardening work takes a long time and cost even in the process of curing after reversing the reinforcing tube; There was a problem that the product is not widely used because it is expensive.

In addition, the vehicle equipped with the reversal device for the repair work on the narrow alleys or roads of the water supply and drainage pipes cannot be moved until the reinforcement and reinforcement of the reinforcement tube are completed. Due to this, there are many difficulties in the movement of a pedestrian or a vehicle, and in the case of a vehicle equipped with a reversing device, since equipment is expensive, it is impossible to own a large number of vehicles, which results in only having to perform maintenance work in one place.

In order to solve the problems, the patent application No. 10-2009-0006208 was filed on January 23, 2009 and registered as a patent registration No. 10-0920794.

Compressed air supplied to the inside of the main body is supplied together so that steam can quickly cure the reinforcing tube.

On the other hand, the steam supplied to the inside of the reinforcement tube is supplied directly to the inside of the main body to quickly cure the adhesive resin layer of the reinforcement tube on the inner wall of the water and sewage pipe, and at the same time, the steam through the steam discharge pipe inserted into the end of the reinforcement tube By discharging to the outside while controlling the pressure and temperature inside the reinforcement tube to increase the adhesion between the inner wall surface and the reinforcement tube to the water and sewage pipes, while reducing the curing time of the reinforcement tube.

However, in this prior art, the steam reaches the end of the pipe in the process of curing by the steam after the reversal, so the water is accumulated in the branch pipe and the water pipe is pushed by the water pressure or the water pipe and the water pipe There is a problem invading between the bottom surface is not cured or the boat is called to harm the tube gradient.

In addition, since the bottom surface of the pipe is heated by steam, the water is accumulated and the portion where the water is accumulated is not properly cured.
