Description

[0001] METHOD FOR REPAIRING AND REINFORCING PIPE LINES WITH NON-EXCAVATION [0002]

The present invention relates to an overhead pipe unrefractured repairing and reinforcing method, and more particularly, to an infiltration tube which is infiltrated with an epoxy or unsaturated polyester resin which is usually used and inflates the infiltration tube inside the upper sewage pipe, The present invention relates to an overhead sewer unrecycled repairing and reinforcing method for producing a synthetic resin regenerating tube in an upper sewer pipe by causing resin curing to occur in a state of being maintained.

Non-digging sewer repair methods are widely generalized techniques. More specifically, a lining material (regeneration tube) impregnated with a synthetic resin (generally, an "epoxy" or an "unsaturated polyester") is introduced into a repair section (a cross section between a manhole for entering a lining material and a manhole ) After inserting, the inside of the upper sewer pipe is dried for a certain time. Thereafter, the piping is pulled out from the upper sewer in front of the upper sewer to be repaired and connected to the lower sewer pipe in the rear of the upper sewer pipe to be repaired, or the piping connection (this is called "turning off the outside water"). In this state, when hot air is blown into the upper sewer pipe, the lining material is brought into close contact with the inner wall of the upper sewer pipe and is hardened.

In this regard, it is disclosed in Korean Patent Laid-Open No. 10-2013-0059083 ("Non-excavated whole repair method", May 31, 2013, "Prior art"). The prior art is related to a non-excavation repair method. Referring to FIG. 1, first, the second and third sewer pipes 1 and 2 are installed in the first upper sewer pipe 1, (4, 5). Thereafter, after the regeneration tube 2 is pulled into the first phase sewer pipe 1 to be repaired, air (high temperature) is injected into the regeneration tube 2 by using the hot air injection device 3, So that the regeneration tube 2 expands and is brought into close contact with the inner wall of the first upper sewage pipe 1. At this time, the regeneration tube 2 is inserted from the inlet 1a of the first upper sewage pipe 1 to the outlet 1b of the first upper sewage pipe 1. However, in the case of using such a method, since hot air or saturated steam must be generated, there is a problem that it is troublesome to install a hot air or a perfume boiler at a construction site and traffic congestion due to space occupation. In addition, in the process of inserting the hot air or the saturated water vapor into the water supply and drainage pipe, there occurs a difference in degree of curing in each impregnated tube (regeneration pipe (2)) due to the temperature difference between the inlet side and the outlet side, .

Especially, in the case of the downtown downtown where the population is concentrated (in the case of the large sub tank), since a large amount of sewage flows close to the full pipe occupying about 70% or more of the total area of the sewage pipe flows, the treatment of the sewage by " There is a concern that environmental pollution, concern about civil complaints due to the generation of odor, traffic congestion, and enormous disposal costs arise.

Hereinafter, the technical idea of the present invention will be described more specifically with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are included to provide a further understanding of the technical concept of the present invention, are incorporated in and constitute a part of the specification, and are not intended to limit the scope of the present invention.

As shown in FIG. 2, the present invention relates to a sewer unrecorded repairing and reinforcing method, which includes a regeneration tube manufacturing step (S100), a regeneration tube inserting step (S200), an upper sewer sealing step (S300) , An outlet connecting step S500, a regenerating tube hardening step S600, a pressure maintaining step S700, and an opening step S800.

The upper and lower sewage unrecorded repair and reinforcement methods each produce a regeneration tube 2 and a resin, and impregnate the regeneration tube 2 with the resin (regeneration tube manufacturing step S100). At this time, the resin is cured at a constant temperature. Thereafter, the regeneration tube 2 impregnated with the resin is inserted into the first upper sewer pipe 1 (regeneration pipe inserting step S200), and the inlet 1a or outlet port 1b of the first upper sewage pipe 1 (Upper sewer sealing step S300). At this time, the inlet 1a is connected to the outlet of another upper drain pipe (the second upper drain pipe 4) in the inlet direction (inlet connection step S400), and the outlet 1b is connected to another upper drain pipe (The third phase sewage pipe 5) or to the outside (outlet connection step S500). Thereafter, air or water is introduced into the first upper sewage pipe 1 to raise the pressure so that the regeneration pipe 2 is brought into close contact with the inner wall of the first upper sewage pipe 1 S600). At this time, it is important to keep the pressure inside the first upper sewage pipe 1 constant during the time when the regeneration pipe 2 is tightly adhered to the inner wall of the first upper sewage pipe 1 S700). Thereafter, when the regeneration tube 2 is cured, the inlet 1a and the outlet 1b are opened (opening step S800). Each step of the above-mentioned sewage unreachable repair and reinforcement method will be described in detail below.

3 (a) and 3 (b), the regeneration tube manufacturing step (S100) produces the regeneration tube 2 and resin, respectively, and impregnates the regeneration tube 2 with the resin. More specifically, the regeneration tube 2 uses a nonwoven fabric material and is made into a cylindrical shape. The regeneration tube 2 is impregnated with the resin on the outer side or the inner side of the regeneration tube 2. At this time, the resin contains at least one selected from a polymer resin, a curing agent, and a curing retarder, and is cured at a temperature of 10 ° C to 25 ° C. The polymer resin includes at least one selected from an epoxy resin and an unsaturated polyester resin. At this time, the recycling tube 2 has a waterproof effect by forming a vinyl coating film 2b of a lining material on the opposite surface of the resin-impregnated surface 2a. Therefore, the resin-impregnated regeneration tube 2 is adhered to the resin-impregnated surface 2a on the inner wall of the first upper sewer pipe 1, and the vinyl coating film 2b of the lining material is formed on the opposite surface thereof, Is not absorbed by the regeneration tube (2).

In addition, the regeneration tube manufacturing step S100 produces the regeneration tube 2 and the resin, respectively, and carries them in a frozen or refrigerated state. More specifically, the resin is cured when a certain period of time elapses. Therefore, the regeneration tube 2 can be transported in a state in which the resin is impregnated, or the regeneration tube 2 and the resin can be manufactured and transported, and the resin can be impregnated into the regeneration tube 2 in the field or in the vicinity of the site do. At this time, when the resin or the resin-impregnated regeneration tube 2 is transported, it is moved in a frozen or refrigerated state. This is because the resin is characterized by being cured at a constant temperature. Since the resin contains the curing retardant, the amount of the curing retardant can be included in consideration of the time for transporting the resin or the resin-impregnated regeneration tube (2).

In the regeneration tube inserting step (S200), the regeneration tube (2) impregnated with the resin is inserted into the first upper sewer pipe (1).

1, the regeneration tube 2 is inserted into the inlet 1a of the first upper sewage pipe 1, and the first upper sewage pipe 1 To the discharge port 1b. At this time, since the outer side of the regeneration tube 2 is impregnated with resin, there is an advantage that the inner side and the outer side of the regeneration tube 2 can be brought into close contact with the inner wall of the first upper sewage pipe 1 without reversing them . However, at this time, there is a problem that it is difficult to insert the reconditioning tube 2 into the first upper sewer pipe 1 due to a severe friction.

4, when the resin is impregnated in the inside of the regeneration tube 2, the regeneration tube 2 is regenerated from the inlet 1a of the first upper sewage pipe 1 by the reversing device, The inside and the outside of the tube 2 are inverted and inserted. More specifically, the reversing device vehicle 6 is provided with a reversing pipe 6a and an inverter 6b. The inversion pipe (6a) is provided with an inverter (6b) at its end. The inversion pipe 6a is connected to the inside of the first upper sewer pipe 1 and flows into the regeneration pipe 2 inside the inversion pipe 6a. The inverter 6b inverts the inside and outside of the regeneration tube 2.

The reversing device vehicle 6 circulates the regeneration tube 2 through the reversing pipe to the inside of the first phase sewer pipe 1 and the reversing device 6b reverses the inside and the outside of the regeneration tube 2, . Since the inside of the regeneration tube 2 is impregnated with resin and the inside and the outside of the regeneration tube 2 are reversed, the inside of the regeneration tube 2 impregnated with the resin is sealed in the first upper sewage pipe 1, I face the inner wall.

When the resin is impregnated in the inside of the regeneration tube 2, it is troublesome to insert the inside of the regeneration tube 2 while inverting the inside and the outside of the regeneration tube 2. However, There is an advantage in inserting into the upper sewer (1).

First, the principle will be described with reference to FIG.

10 is a schematic diagram for explaining the basic principle of the internal water turning. 10A shows a state in which the air A is filled in the first upper sewage pipe 1 when the diameter of the first upper sewage pipe 1 is 300 mm and the air A is filled in the first upper sewage pipe 1, (Water or water) (B) at 25%.

The principle of the present invention will be described with reference to Figs. 10A and 10B. Assume that the air pressure of the first upper sewer pipe 1 in Fig. 10A is 2,000 mmAq, and the air in the closed pipe is assumed to be an ideal gas. The air pressure of the remaining 75% air layer excluding the constant or the wastewater B in the first upper sewer pipe 1 of Fig. 10B is calculated as 6,110 mmAq. This means that the pressure (P) increases as the volume (air layer) (V) decreases because the constant of pressure (P) * volume (V) is constant at P * V = mRT do. Therefore, when the inflow amount of the water or wastewater into the first upper sewage pipe 1 (or the regeneration pipe 2) is regulated, the air pressure rises and the regeneration pipe 2 is brought into close contact with the inner wall of the first upper sewage pipe 1 do. At this time, it is important to adjust the inflow amount of air, water or wastewater to keep the pressure constant until the time when the recycling pipe 2 is cured on the inner wall of the first upper sewage pipe 1.

Using this principle, the first upper sewage pipe 1 is supplied with a constant water, wastewater or air through the inlet packer 10 fixed to the inlet 1a. The internal pressure of the first upper sewage pipe 1 is increased due to the water, wastewater or air flowing into the first upper sewage pipe 1. At this time, the regeneration tube 2 bulges by the pressure inside the first upper sewage pipe 1 and is brought into close contact with the inner wall of the first upper sewage pipe 1. Further, the recycling tube 2 has a vinyl coating film of a lining material formed on the inner wall thereof, and has a characteristic (waterproof) that air or water is not circulated. Thereafter, the inflow of the constant water, the fresh water or the air is controlled so that the pressure inside the first upper sewage pipe 1 is kept constant, or the inflow of the constant water, the fresh water or the air from the outlet 1b of the first upper sewage pipe 1 To the outside. When the regeneration tube 2 is cured, the pressure inside the first upper sewage pipe 1 is lowered, and the inlet packer 10 and the outlet packer 20 are removed. With this method, it is possible to repair the first upper sewage pipe 1 while flowing water into the first upper sewage pipe 1 without turning the water to the outside when repairing the first upper sewage pipe 1 There are advantages.

The pressure holding step S700 is a step of discharging the air or water in the first upper sewage pipe 1 to the third upper sewage pipe 5 or the outside during the period during which the regenerating pipe 2 is cured, (1) Maintain a constant internal pressure. That is, the pressure holding step S700 measures the pressure inside the first upper sewage pipe 1 to control inflow of air or water so that the pressure inside the first upper sewage pipe 1 is constant, And controls the discharge of air or water inside the sewer pipe (1).

The main control unit 300 is connected to the inlet control unit 110 and the outlet control unit 210 to control the inlet control unit 110 and the outlet control unit 210.

Also, the main control unit 300 may include a power device. The main control unit 300 receives power from the electric power distribution panel or electric power near the generator, the manhole, and distributes the power to the inlet controller 110 and the outlet controller 210.

That is, the main controller 300 controls the air compressor 101, the inlet valve 102, and the outlet valve 202 according to the pressure value in the first upper sewer pipe 1 measured by the outlet manometer 201, . At this time, the main control unit 300 controls the inflow valve 102 or the discharge valve 202 so that the pressure inside the first upper sewage pipe 1 is maintained at a constant pressure.

In addition, the main control unit 300 may further include a PC. The main control unit 300 receives information measured by the pressure gauge 201 from the discharge control unit 210 and transmits the information to the PC. At this time, the PC is composed of a notebook or a desktop computer. In addition, the PC communicates with the main control unit 300 in a wired or wireless manner to display an operation state of various drive devices, or to enable operation control. In addition, the PC displays the measured information from the pressure gauge 201 in real time as a pressure graph over time.

The main control unit 300 transmits driving command signals of the various driving devices to the inlet control unit 110 and the outlet control unit 210 via the PC or directly.

In the opening step S800, after the regeneration tube 2 is cured on the inner wall of the first upper sewage pipe 1, the inflow of air or water flowing into the first upper sewage pipe 1 is blocked, The air or water in the upper sewage pipe 1 is discharged to open the inlet 1a or the outlet 1b of the first upper sewage pipe 1.
