Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous inverting apparatus for repairing irrigation water and sewage,

More particularly, the present invention relates to an inverting apparatus for repairing irrigation water supply and drainage, and more particularly, to a reversing apparatus for repairing irrigation water supply and drainage, and more particularly, And close proximity reversal can be performed. Also, by adopting the double air injection system, it is possible to perform reversal even at a low air pressure, so that a continuous reversing device for unreachable water supply and sewerage which is very economical and applicable to the field, And a method for repairing water and sewage.

Generally, in case of various industrial pipes such as water and sewage, gas, electricity, telecommunication, oil pipelines, and seawater pipes, etc., the tube liner impregnated with resin is introduced into the pipe and then cured with heat to form a new pipe. CIPP, Cured in place pipe) lining method.

The background art of the present invention can be confirmed by Korean Patent No. 10-1433182 and Korean Patent No. 10-0545483.

The conventional drum-type reverser in which a heat hose and a tube liner are wound is provided with an air compressor and a vehicle equipped with a generator. The tube liner is transferred to a circular And the end of the tube liner is connected to the inlet of the tube to be inverted as it is to the maintenance tube so that the tube liner is exposed for a long time. .

Unlike the conventional method in which the tube liner is wound or loaded in the inside of the inverter such as a large drum type inverter or a box type inverter installed in the vehicle, inverting is started at the inverter inlet, It is a maintenance tube continuous reversing device capable of continuously reversing through this reversing device when the vehicle is continuously supplied.

In addition, conventionally, since the tube liner has to be mounted inside the reversing device, it is necessary to increase the size of the reversing device, and there is a large space where the pressure air and heat stay in the inside of the inverter, and the length of the tube liner exposed during the remote reversing is long, Which caused the increase of the cost of production and the cost of construction.

Conventional conventional continuous inverters have a structure in which a tube liner is fixed to a reversing sphere similar to a general reversing device, a device for sealing the inside of the tube liner to push the tube by pneumatic pressure, and a device for sealingly closing the inside of the transducer. It is difficult to judge originality.

Because of this, the self-propelled caterpillar is mounted on the reversing machine so that the work area can be entered more easily than the on-board type reversing machine, the small moving part is free and the tube feeding device is placed inside to forcibly push the drawn tube, However, there is also the inconvenience that the self-propelled device and the transfer device are integrated into the reversing device, which is large like a large-sized reversing device and there are many electric control devices.

In addition, Korean Patent No. 10-1433182 discloses that since the reversing and curing operation must be performed by sealing only the inversion section for fixing the tube, the tube liner which is drawn in a straight line in the short reversing tube space must be unfolded and inverted, As the pressure increases and the up and down airtight interrupter presses the tube liner with strong force, there is a lot of surface damage on the tube liner, and since it is difficult to adjust the sealing to the thickness and width of the tube liner, There is a problem that the efficiency of inversion is low due to a large amount of air.

The invertor fixing rail 34 is configured such that a slider 26 formed in the invertor 20 is movably mounted and that the invertor 20 is assembled to the invertor housing 10 with a small force Advantageously, there is an advantage that the inverter housing 10 and the frame 30 can be separated from the inverter 20 by a small force while the inverter 20 is fixed to the maintenance line 2.

The inverting housing 10 has a tubular structure in which a space is provided therein. The inverting connector connection portion 12 is connected to the inverting opening 20 at the front side of the inverting housing connection portion 10, An air inlet 14 formed on the rear surface of the housing main body 11 and a hot air inlet 15 formed on the rear surface of the housing main body 11.

The housing main body 11 guides the tube liner 1 inserted through the liner inlet 13 to the inversion tool 20 and provides a space in which the high pressure compressed air injected through the air inlet 14 can be filled The portion of the front half of the inverted bulb connecting portion 12 except for the liner input opening 13 is in a hermetically closed structure where the rear liner input opening 13 is located.

A soft curtain 16 is applied to the liner inlet 13 so that compressed air and hot air inside the housing body 11 do not leak to the outside. The curtain 16 is composed of two upper and lower soft sheets 16a and 16b in consideration of the fact that the tube liner 1 is supplied in a folded state.

It is preferable that the curtains 16 are made of two or more incisions at a certain distance from each other so as to seal the liner inlet 13 in accordance with various sizes of the tube liner 1. [

The upper and lower soft sheets 16a and 16b are respectively arranged in a plate shape and vertically arranged so that the distal end of the soft sheets 16a and 16b is fixed to the rear wall of the housing main body 11 And the free ends of the tube liner 1 are brought into close contact with the circumferential surface of the tube liner 1 due to the softness characteristics, (Compressed air, heat) inside the casing 11 is prevented from leaking to the outside.

The air inlet 14 and the hot air inlet 15 are formed to pass through the rear wall of the housing main body 11 so that the inside and the outside of the housing main body 11 communicate with each other and the air hose and the heat hose are connected to each other.

The air inlet 14 and the hot air inlet 15 may be provided separately, but one inlet may be shared.

The reflector housing 10 is provided with an observation window 17 for checking the supply state and the like of the tube liner 1 from the outside and a thermometer 18 and a pressure gauge 19 for confirming the temperature and pressure .

The inverting electrode 20 is formed on the inverting electrode body 21 and the inverting electrode body 21 which are detachably connected to the inverting electrode connecting portion 12 of the housing main body 11 and the compressed air is injected into the tube liner 1 And one or more front side compressed air nozzles (22) for reversing the tube liner (1).

The tubular body 21 has a tubular structure (cylindrical shape) having both sides in the longitudinal direction thereof opened. The tubular body 21 may have a tapered shape whose diameter progressively narrows toward the front, It is possible to induce rapid reversal of

The inverting body 21 is connected to the inverting connector 12 of the inverting housing 10 and the inverting body 21 and the inverting housing 10 can be connected in various ways. There is a method in which the opposing body 21 and the opposite end of the semi-conductive housing 10 are fastened with a clamp. Here, it is preferable that the packing is applied so as to prevent leakage of compressed air and heat at the connection portion with the transient housing 10.

A front side compressed air nozzle 22 is formed in the periphery of the inversion valve body 21 and compressed air injected from the compressed air nozzle 22 is pushed into the tubular liner 1 to invert the compressed air A guide 23 is applied.

The compressed air guide 23 has an outer diameter smaller than the inner diameter of the inverting body 21 so that a space is formed between the compressed air guide 23 and the inverting body 21.

The compressed air guide 23 may have a structure in which one side is fixed to the inverting body 21 and the other side is protruded toward the front side of the inverting body 21. [

The compressed air guide 23 may be provided with a guide 23a at its distal end for guiding the compressed air injected from the front side compressed air nozzle 22 toward the tube liner 1. [

3 and 4 illustrate the shape of the guide 23a, and the guide 23a may have various shapes such as a straight line as shown in FIG. 3, an extended gradient as shown in FIG.

The front side compressed air nozzle 22 is formed so as to communicate with the inside and the outside of the compressed air guide 23 behind the guide 23a of the compressed air guide 23 and to supply the compressed air supplied into the inside of the antireflective housing 10 The air is guided to a space between the compressed air guide 23 and the inverting body 21 or the compressed air is injected to the outside of the inverting body 21 and guided to the compressed air guide 23.

The front side compressed air nozzle 22 is formed on the periphery of the compressed air guide 23 one or more than two.

5 and 6 are schematic views showing the reversal of the conventional tube liner and the reversal of the tube liner 1 by the front side compressed air nozzle 22. As shown in Fig. 5, conventionally, the tube liner 1 is fixed The present invention is applied to a case where the tube liner 1 is fixed at a position spaced rearward (air inlet 14) as shown in Fig. 6, while the tube liner 1 is inverted only through the force of compressed air introduced from a space away from the tube liner 1, The difference is that the tube liner 1 is reversed through the force of the compressed air flowing from the front side compressed air nozzle 22 and the force of the compressed air injected from the front side compressed air nozzle 22 close to where the tube liner 1 is fixed have.

In addition, at the periphery of the compressed air guide 23, one or more vortex guiding vanes 24 may be formed, as shown in FIG. 7, for the vortex formation of the compressed air injected through the front side compressed air nozzle 22 have.

The vortex guiding vane 24 is bent at an angle to form a vortex.

As shown in FIG. 8, it is also possible to form a straight blade 25 in place of the vortex guidance vane 24. FIG.

The present invention is characterized in that the inverting electrode 20 is used separately from the inverted housing 10, for example, after the reversal of the tube liner 1 is completed, The heat exchanger 20 is separated from the heat exchanger 20 and the heat exchanger 20 is left only in the repair duct 2 and the heat hose is connected to the reversing tool 20 to supply heat at a high temperature into the tube liner 1, .

Therefore, the reversing tool 20 is provided with a finishing plate 27a on the opposite side of the front side compressed air nozzle 22 so that only the liner inputting opening 27 is opened as an opening for reversing the tube liner 1, A reversing port closing port 28 for closing the liner input port 27, and a hot air port 29 for connecting the heat hose.

The finishing plate 27a may be integrally formed with the reversing tool 20, but it may be detachable to the reversing tool 20 for the case where the inflation tubes 40 described later are applied. That is, the finishing plate 27a may be pre-mounted on the inverter 20 and used when the inverter 20 is separated from the inverter housing 10 and cured.

Since the liner input port 27 of the reversing tool 20 is of such a size that the tube liner 1 of all sizes can be inserted and is closed by the reversing port closing port 28, the left and right airtightness Plates can be applied without applying.

The reversing opening 28 closes the liner inserting opening 27 so as to prevent hot air from leaking through the liner inserting opening 27. The reversing opening 27 can be formed in various forms such as a lifting type and a pivoting type on the finishing plate 27a, The liner inlet 27 is sealed before the separator 10 is detached.

Of course, the finishing plate 27a is not applied as long as it can seal the rear of the reversing tool 20 through the reversing cap 28. [

It is also possible not to apply the hot air inlet 29 by injecting the hot air through the liner inlet 27.

It is possible to prevent reverse flow of the compressed air injected into the inside of the inverter housing 10 to prevent the reverse speed from being reduced due to the prevention of reverse flow, and this is possible by the expansion tube 40 (FIG. 9).

The inflation tube 40, which is a backflow prevention device, expands through the fluid to be injected into the tube liner 1 and is injected into the tube liner 1 in such a manner as to block the inside of the reversing opening 20 without interfering with the reversal of the tube liner 1 So that the compressed air does not flow back into the inverter 20. [

The expansion tube 40 can be both inserted into the tube liner 1 and outside the tube liner 1.

For example, as shown in FIG. 10, a fluid may be injected from the front side of the tube liner 1 into the inflation tube 40 (inflated state, but it may be expanded to easily insert it into the inside of the antireflective housing 10 The tube liner 1 is inserted into the reversing device 100 and the expansion tube 40 is inserted into the inverting device 100 at a predetermined distance from the one end of the tube liner 1 (A) Place one end of the tube liner 1 on the tip of the reversing device 100 and fix it. At this time, the tube liner 1 is supplied through the movable supply stand 200 which supplies the tube liner 1 to the inverting apparatus 100 from the outside of the inverting apparatus 100.

When the end of the tube liner 1 is fixed to the inversion device 100 and the supply bag 200 is brought close to the inversion device 100 and compressed air is injected into the inversion device 100, the tube liner 1 is inverted The expansion tube 40 is inserted into the inverting apparatus 100.

When the fluid is injected into the expansion tube 40, the expansion tube 40 closes the inverting opening 20, and when the compressed air is injected for reversing the tube liner 1, the compressed air pushes the expansion tube 40 The compressed air injected in front of the expansion tube 40 is not backwashed by the expansion tube 40 although the tube liner 1 is sprayed onto the tube liner 1 to reverse the tube liner 1.

In addition, the present invention can more effectively prevent leakage of compressed air and heat through the liner inlet port 13, and more effectively prevent the leakage of the compressed air and heat through the liner inlet port 13 by using a lift-off sealing plate 50 (Fig. 11) can be applied.

The lift-off sealing plate 50 may be constituted by a plurality of (for example, three) unit sealing plates 51, 52 and 53, that is, a number corresponding to the width of the tube liner 1 The effect of maximizing the airtight effect is obtained by selecting and using the sealing plate.

The plurality of unit sealing plates 51, 52 and 53 are arranged in a line in accordance with the width of the tube liner 1 and are provided with protrusions and grooves on opposite faces to prevent gas from leaking through the spaces 51, Interlocking is performed by the groove and the projection.

Fig. 12 shows an example in which all the unit sealing plates 51, 52 and 53 are used, and Fig. 13 shows an example in which only one unit sealing plate 51 disposed in the center is used.

The lift-off sealing plate 50 may be provided only on the upper portion of the liner input opening 13, and the lower wall of the lift housing 10 is disposed on the rear wall of the inverter housing 10. Conversely, the elevating sealing plate 50 may be installed only at the lower portion of the liner inlet 13, or may be installed at both the upper portion and the lower portion, as shown in FIG.

The elevating sealing plate 50 ascends and descends through an actuator, and the actuator can be configured in various ways such as a hydraulic type (hydraulic cylinder), a screw type, and the like.

The elevating sealing plate 50 may be configured to be installed inside or outside of the curtain 16 so as to be capable of double sealing with the curtain 16 or a soft curtain 16 may be provided, It is also possible to raise and lower it.

As described above, one or more of the unit sealing plates 51, 52, 53 of the lift-up sealing plate 50 are selected and used so as to fit the width of the tube liner 1, The left and right widths of the tube liner 51 may be larger than the width of the tube liner 1 and therefore the left and right empty spaces of the tube liner 1 are left, The left and right airtight plates 54 can be applied.

The left and right airtight plates 54 are provided so as to be movable to the left and right of the elevating and closing plate 50, and can move left and right inside the unit closings 51, 52, 53 in order to increase the airtight effect and reduce the overall volume. .

To this end, grooves 51a, 52a, 52b are formed in the unit sealing plates 51, 52, 53 so that the left and right airtight plates 54 can be moved leftward and rightward, 53a are formed.

The left and right airtight plates 54 are configured to adjust the distance between the left and right airtight plates 54 by means of the width adjusting means. The width adjusting means is arranged along the left and right width direction of the liner inputting opening 13, And a screw 55 screwed to the nut 54 (nut part construction).

The screw 55 has a pair of right and left airtight plates 54 together when the screw 55 is rotated in one direction, and a pair of right and left airtight plates (54) together.

The screw 55 can be manually rotated with a knob at its end, or can be rotated electrically by a switch operation connected to an electric motor.

13, when only one center unit sealing plate 51 is used, the left and right airtight plates 54 are moved to the right and left sides of the unit closing plate 51 so as to fit the width of the tube liner 1, Thereby preventing the fluid in the inverting apparatus from leaking through the liner inlet 13 by blocking the left and right lower spaces of the plate 51. 12 shows the case where all of the elevating sealing plates 50 are used and the left and right air sealing plates 54 are disposed at both left and right ends of the elevating sealing plate 50 to form the liner inlet 13. [

As another example, as shown in Fig. 15, upper and lower spaces may be provided for reinforcement of the curtain 16 having a low airtightness when the integral lifting type sealing plates 50-1 and 50-2 are closed and the curtain 16 is closed to the left and right. A plate magnet 56 may be applied. The plate magnets 56 are composed of one or more plates and are attached to the semi-electrical housing 10 to seal the liner inlet 13 by blocking the remaining space left on both sides of the tube liner 1.

The present invention is a method of supplying heat to the inside of the inverted tube liner 1 to cure the tube liner 1 so that the heat hose 60 for supplying heat into the tube liner 1 (Figs. 16A, 16B, 17 and 18) is applied. Particularly, the heat hose 60 is applied with the compressed air bag 61 so that heat is supplied only to the tube liner 1, that is, the heat is supplied only to the tube liner 1 without flowing back toward the reverser.

The compressed air bag 61 is connected to a position spaced apart from a discharge port at one end of the thermal hose 60 and expanded by a fluid (hot air, compressed air, etc.) supplied to the heat hose 60, As shown, the peripheral portion is in close contact with the inner surface of the tube liner 1, so that the fluid injected through the discharge port can not flow backward.

The heat hose (60) is made of a reinforced tube that can withstand the supplied heat and can withstand high-pressure steam or dry steam.

The compressed air bag 61 is a material which can withstand heat and is easy to inflate, and may be a separate soft tube or a tube liner. In this case, both the longitudinal air bag 60 and the heat air bag 60 are connected to the heat hose 60, 60 is inserted into the compressed airbag 61 (a hole is formed in the thermal hose 60 inside the compressed airbag 61 to inject the fluid into the compressed airbag 61).

The compressed air bag 61 may be a separate injection port in addition to the fluid to be injected into the thermal hose 60, so that a separate fluid may be directly injected.

A swirl generator 62 such as a propeller-type rotary turbine or a fan may be applied to the discharge port of the thermal hose 60. When the fluid is discharged, the swirl generator 62 rotates, formation and therefore a wide range of the fluid to be spread it inside the liner tube (1) by improving the thermal efficiency can increase the rate of heat transfer to and it is possible to shorten the period during construction.

The heat hose 60 is fixed to the tube liner 1 so that the discharge port can be naturally disposed in front of the maintenance tube by the reversal of the tube liner 1. [

An inversion method using the continuous inverting apparatus for repairing irrigation water supply and drainage according to the present invention is as follows (see FIG. 17).

1. Reversing device mounting.

The inverting apparatus 100 is mounted on the ground around the manhole in accordance with the position of the maintenance line 2 and the inverting apparatus 100 is vertically movable in the horizontal direction as shown in FIG. It is also possible to mount it.

2. Install the tube liner.

The tube liner 1 is inserted into the liner inlet 13 of the inverter housing 10 and the end is fixed to the inverter 20 so that the end of the tube liner is turned upside down from the outside of the inverter 20, And then fixed to the periphery of the reversing tool 20. [

3. Install the thermal hose.

The compressed air is injected at a high pressure through the compressed air inlet of the transient housing 10 to advance the tube liner 1 to the inlet of the maintenance channel 2 by reversing the compressed air in the inverting apparatus 100 , The observation window 19 is opened to insert the thermal hose 60 into the inverting apparatus 100 and the end portion (inlet portion) of the thermal hose 60 is fastened to the hot air inlet 15.

If no heat hose is applied, the process will not proceed.

3. Reverse tube liner.

When the high pressure compressed air is injected through the compressed air inlet 14 for the reversal of the tube liner 1, the compressed air pushes the tube liner 1 to invert the compressed air, The tube liner 1 is inverted by pushing the tube liner 1 in front of the air inlet 14 through the air inlet 14.

That is, while the tube liner 1 is reversed only by the force injected through the air inlet, the present invention is also applicable to a case where the tube liner 1 is fixed via the front side compressed air nozzle 22, By reversing the liner 1, the reversal speed is shortened.

When the thermal hose 60 is applied, compressed air is injected into the reversing device 100 after the heat hose 60 is installed, and when the reversing is started, the tube liner 1 advances through the reversing device 100 In this process, the heat hose 60 is placed on the tube liner 1 and pulled up to the inlet of the maintenance duct 1.

3. Curing.

When heat is supplied to the hot air inlet 15 for hardening after completing the reversing operation of the tube liner 1, the compressed airbag 61 in the middle of the hot hose, which is long to the inlet of the duct, And the rear of the discharge port of the heat hose 60 is sealed to thereby effect effective heat conduction. When heat is supplied to the heat hose 60 in a state in which heat is cut off by the compressed air bag 61 (the heat supply hose is connected to the hot air inlet 15 which is the inflow side end of the heat hose 60, The resin inside the tube liner 1 inverted through the discharge end of the thermal hose 60 is hardened and a maintenance layer made of the hardened tube liner 1 is formed on the inner wall of the repair pipe 2. [

After the resin of the tube liner 1 is cured, the tube liner 1 outside the maintenance line 2 is cut and closed.

19 is a view showing another construction method according to the present invention.

In the repairing of the sewer pipe or the water supply pipe, it is possible to place the continuous inverting device 100 for unreachable water supply and sewage maintenance in the underground work place, and therefore, it is positioned close to the maintenance pipe. At this time, the continuous irrigation apparatus 100 for repairing irrigation water supply and drainage of the present invention is installed in a maintenance channel by using the entire continuous inverting apparatus 100 for irrigation water supply and drainage repair at the time of reversal operation, and the tube liner 1 is provided with a separate movable supply The stand 200 is placed in the underground work station and positioned in a straight line on the rear surface of the inverter housing 10 or a separate movable stand 200 is brought close to the tube liner loader on the work site or the freezer 300 And the reverse operation is carried out by pulling it up to the liner input opening of the semi-conductive housing 10. [

In the repair work where the inversion and hardening operations can be performed in the vicinity of the maintenance line, the reversing tool 20 can be directly fastened to the maintenance channel to eliminate the separate insertion of the heat hose airbag. And thus it is possible to reduce material consumption and heat loss, which is very efficient.

When the inverting operation is completed, as shown in FIG. 20, the inverting opening 20 is closed through the inverting opening 28 and the inverting housing 10 and the frame 30 are separated from the inverting opening 20, It is possible to perform a hardening operation by moving the work hose to the ground or the like and disposing a heat supply device 400 on the ground and connecting the heat hose 410 of the heat supply device 400 to the reversing tool 20. [ Therefore, it is possible to construct even in a narrow working space, and it is also possible to reduce the heat loss by using only the inverter 20. Also, since the inverter housing 10 can be continuously used, Since only the inverting electrode 20 is connected to the maintenance channel 2 even when a long cooling operation is required, variable operation of the inverter housing 10 is possible until curing after curing operation.

A curing tube is formed in the maintenance tube 2 by the curing of the tube liner, the inside of the curing tube is in a high temperature state, and a cooling step of cooling the curing tube for further quick construction may be further included.

The cooling step may use a heat hose 60, a hot air inlet 15 or 29, or a front side compressed air nozzle 22. By supplying low-temperature air to each injection port and keeping the inside of the curing pipe at a low temperature The curing tube is cooled.
