The present invention relates to an energy-saving branch pipe repair and reinforcement device and method using an LED light source to improve durability while significantly reducing energy use compared to the method.

Sewage pipes are generally damaged at the junction between the main pipe and branch pipes, and surface water often flows into the sewer pipe, and the above damage is the cause of further damage to the sewer pipe as well as soil flow into the damaged part. Various studies have been conducted on non-excavation repair equipment and construction methods for wealth.

As an example of such a non-drilling repair and reinforcement method, in Korean Patent Registration No. 10-0594825, in the non-drilling sewage pipe repair and reinforcement hose lining method in which a hose liner is installed and hardened inside the sewer pipe, the hose lining method is (a ) The process of inserting a CCTV-equipped robot into the sewer pipe section (A) to be repaired and reinforced among sewer pipes with an inner diameter of 200 to 1200 mm, photographing the inside of the sewer pipe, and inspecting the inside of the sewer pipe, and confirming the damaged part (B); (b) a process of blocking the inflow of upstream sewage by installing a blocking device for water supply on the upstream (C) side of the sewer pipe section (A) to be repaired and reinforced; (c) a step of washing the sewer pipe section to be repaired and reinforced using a sewer washing vehicle; (d) inserting a pre-liner into the sewer pipe section (A) to be repaired and reinforced; (e) inserting a liner hose made of glass fiber reinforced plastic on the preliner and supplying compressed air to the liner hose to expand the hose; (f) After inserting the UV light lamp curing vehicle into the expanded liner hose, install water-repellent packers on the upstream (C) and downstream (D) sides of the sewer pipe section (A) to be repaired and reinforced.

However, in the application of the above technology, there is a problem that sufficient repair and reinforcement for damaged parts such as cracks in the joint between the main pipe and the branch pipe cannot be expected.

In particular, in the case of the above-described conventional technology, an example in which a UV light lamp is applied alone in the curing process is presented. As a result of the use of the lamp to irradiate UV wavelength light, a lot of energy must be consumed. Due to the shortcomings of a short service life and a short replacement cycle, there is an uneconomical problem due to an increase in construction cost as well as maintenance cost in operating the device.

Hereinafter, the configuration and operation of the present invention will be described in more detail based on the accompanying drawings. In describing the present invention, terms or words used in the present specification and claims are the present invention based on the principle that the inventor can appropriately define the concept of terms in order to explain his or her invention in the best way. It must be interpreted as a meaning and concept consistent with the technical idea of

1, the branch pipe repair and reinforcement device of the present invention includes a curing means 20 and an air injection means 21 for irradiating an LED light source therein, and the LED light source by the curing means 20 is The body part 22 in which the "T"-shaped packer 220 is formed while being irradiated to the outside by the air injection means 21 and the moving means 23 mounted at both ends of the body part 22 respectively ) And the inner periphery of the branch pipe 1 to be repaired by the movement of the moving port 2 and the expansion of the packer 220 and mounted on the “T”-shaped packer 220 And a repair member (3) that is attached to and cured while attached to the branch pipe (1) to be repaired by the LED light source irradiated from the curing means (20).

That is, the branch pipe repair and reinforcement device of the present invention allows the maintenance and reinforcement with excellent watertightness and rigidity to the branch pipe 1 in which defects such as deterioration occurred as the repair member 3 is hardened.

First, the moving port 2 is provided with moving means 23 at both ends of the body part 22 to move the maintenance member 3 to a position where the branch pipe 1 to be repaired is located inside the pipe. It operates so that the maintenance member 3 can be in close contact with the pipe 1.

The moving means 23 may have one or more wheel structures as shown in FIG. 1, and in this case, the wheels are configured to be hinged to each other so that they can be applied to pipes having different diameters.

As shown in FIG. 2, the body part 22 has a curing means 20 and an air injection means 21 therein, and the curing means 20 and the air injection means 21 are various known technologies. Since there is a detailed description thereof will be omitted.

The body portion 22 is formed with a "T"-shaped packer 220, which protrudes from the body packer 220-1 and the body packer 220-1 facing the main pipe portion of the pipe, so that the branch pipe 1 It may be composed of a protruding packer 220-2 facing each other.

The body part 22 is a branch pipe 1 in which a defect is generated by the moving means 23 in a state in which the maintenance member 3 and the like are placed in the "T"-shaped packer 220 in a state that is not expanded. ) After the movement port 2 moves to the part, the “T”-shaped packer 220 expands due to the operation of the air injection means 21, and the maintenance member 3, etc. 1) It is in a state so as to be in contact with the main pipe, and in this state, the repair member 3 is cured by light or heat irradiation of the curing means 20.

The state in which the repair and reinforcement is made is shown in FIG. 4. That is, the skirt part 32, which will be described below, is attached to the main pipe part P1 in the pipe line P, and the straight pipe part 31 is attached to the branch pipe P2.

Meanwhile, the repair member 3 is integrally formed with the straight pipe part 31 and the straight pipe part 31 attached to the inner periphery of the branch pipe 1 to be repaired, and has a diameter in the downward direction from the straight pipe part 31. It has a larger shape and includes a skirt portion 32 attached to the inner periphery of the main pipe portion of the pipe that is connected to the branch pipe (1).

The maintenance member 3 is a branch pipe 1 and a member attached to the main pipe portion of the pipe is integrally formed to facilitate mounting on the "T"-shaped packer 220 of the moving port 2, and There is no seam between the part 31 and the skirt part 32, so that the water tightness may be further doubled.

According to the prior art, it is composed of a plurality of patches and the overlapping part is formed between each of the patches, so that the repair member is attached to the main pipe and branch pipe by the relaxation of the overlapping part. In this case, the watertightness is lowered at the overlapping part. There is a problem that the process of placing it so as to be formed is not easy, but the repair member 3 proposed in the present invention is made of a material having an elasticity in which the branch pipe 1 and the part facing the main pipe part of the pipe are integrally formed. It is configured so that the overlapping portion does not need to be formed, as in the prior art mentioned above, so that workability is facilitated, and the watertightness decrease factor due to the formation of the overlapping portion is controlled.

The repair member 3 is hardened by at least one selected from light irradiation or thermal irradiation in a state in close contact with the inner periphery of the branch pipe 1 where the defect has occurred and the inner periphery of the main pipe part of the adjacent pipe. 1) Reinforce the rigidity and ductility.

At this time, the repair member 3 allows the curing by the LED light source to be started during the curing process by the curing means 20, thereby minimizing the energy required for curing the repair member 3.

For example, the straight pipe part 31 and the skirt part 32 are a geotextile sheet 300 in contact with the inner circumference of the branch pipe 1 to be repaired and the inner circumference of the main pipe part of the pipe connected to the branch pipe 1 and It may be configured to include a curable resin 310 including a photoinitiator 311 which is impregnated in the geotextile sheet 300 and cured by photoinitiating reaction to an LED light source.

The curable resin 310 is configured in a state impregnated with the geosynthetic sheet 300 as mentioned above.

The curable resin 310 is a known photocurable resin or a thermosetting resin or a photocurable resin and a thermosetting resin to be included together, so that the light irradiated from the curing means 20 while impregnated in the geosynthetic sheet 300 or It hardens in response to heat.

The geotextile sheet 300 is configured in a state impregnated with the curable resin 310, and may be, for example, a glass fiber sheet.

That is, the geosynthetic sheet 300 is composed of a high-strength and highly ductile glass fiber sheet to further strengthen strength, and in the case of a pipe buried in soft ground by increasing elasticity (ductility), it can accommodate deformation due to differential settlement. It will be possible.

When the geotextile sheet 300 is a glass fiber sheet, the curable resin 310 may be impregnated in the gap between the glass fiber yarns constituting the glass fiber sheet, and in particular, a curable resin in the curing process by heat or light irradiation ( Since the impregnation resin) is hardened in the state where it is filled in the gap between the glass fiber yarns, in addition to the rigidity, the watertightness can be doubled.

The glass fiber sheet may be constructed by weaving of glass fibers, and at this time, it is preferable that the glass fiber is woven so that the skirt part 32 is relatively more elastic than the straight pipe part 31.

In addition, the curable resin 310 may include a photoinitiator 311 that is cured by photoinitiating reaction to an LED light source.

The photoinitiator 311 is a monomer that absorbs light to form a radical in a triplet state, and the light-initiating reaction to the LED light source irradiated from the curing means 20 described below, and the repair member 3 To cure.

Meanwhile, the curing means 20 irradiates one or more of light or heat so that the repair member 3 can be cured.

That is, the curing means 20 is provided inside the body part 22 of the moving tool 2 and irradiates heat or light toward the repair member 3 or irradiates heat and light in parallel, so that the repair member 2 The curable resin 310 is to allow the curing reaction to be carried out.

The curing means 20 is an LED toward the inner circumference of the main body 200 installed inside the body part 22 of the moving tool 2 and the branch pipe 1 to be repaired as shown in FIG. It may include an LED lamp 201 mounted on the main body 200 so that the light source is irradiated.

For example, the main body 200 is installed in a fixed form on the protruding packer 220-1 of the "T"-shaped packer 220, or the protruding packer 220-1 of the "T"-shaped packer 220 ) May be installed so as to be elevated along the longitudinal direction of the protruding packer 220-1.

In addition, the LED lamp 201 is an LED light source having a plurality of LED elements 202 mounted along the front outer periphery of the main body 200 and passing through the protruding packer 220-1 of the "T"-shaped packer 220 This can be made to irradiate the repair member (3).

The LED light source irradiated from the LED lamp 201 reacts the photoinitiator 311 included in the curable resin 310 of the repair member 3 so that the repair member 3 can be cured.

In particular, the light irradiated from the LED light source may be UV (ultraviolet) wavelength, that is, 100 to 405 nm light, most preferably UV-A (315 to 405 nm) may be configured to irradiate light.

In addition, the curable resin 310 of the repair member 3 may be a photocurable resin in which a curing reaction is performed at a UV wavelength.

That is, the curable resin 310 is a photocurable resin containing a photoinitiator 311, and the LED lamp 201 reacts to light initiation by the LED light source of the LED lamp 201 and curing proceeds, and the LED lamp 201 is in the UV wavelength band. By irradiating the light of the repair member 3 is to be completely cured.

As described above, in the branch pipe repair and reinforcement device of the present invention, the light curing method using the conventional UV lamp alone can be replaced with the LED lamp 201, and the light irradiation by the LED light source uses energy rather than the general UV lamp application conditions. It is more effective in terms of maintenance as it has a long lifespan and durability that can be operated for up to 25,000 hours.

In addition, while a general UV lamp contains mercury, the LED light source does not contain any environmentally harmful substances, so there is an effect that the device can be operated environmentally.

Such a curing means 20 is not shown in the drawing, but it is connected to a control unit provided on the ground through a wired or wireless communication network to receive power, and heat or light irradiation together with the lifting operation of the main body 200 by an operator To be controlled.

Meanwhile, in the branch pipe repair and reinforcement device of the present invention, in constituting the curing means 20, the LED lamp 201 is installed in front of the main body 200 so that the curable resin 310 is cured by the initial light initiation reaction. After allowing the process to proceed, an example in which a different type of heat or light irradiation device is additionally installed at the rear so that the thermosetting or photocuring of the curable resin 310 can be completed is presented.

For example, the curing means 20 is an LED light source toward the inner periphery of the main body 200 installed inside the body part 22 of the moving tool 2 as shown in FIG. 6A. In addition to the LED lamp 201 mounted on the main body 200 to be irradiated, the main body 200 is relatively rearward than the LED lamp 201 toward the inner periphery of the maintenance target branch tube 1 It may further include a UV lamp 203 mounted to irradiate a light source in the UV (ultraviolet) wavelength band.

At this time, as mentioned above, the main body 200 may be installed in a fixed form on the protruding packer 220-1 or may be installed so as to be elevated along the longitudinal direction of the protruding packer 220-1, In this embodiment, the LED lamp 201 and the UV lamp 203 are selectively operated, but after the LED lamp 201 is operated in advance with a set time difference, the UV lamp 203 is controlled to operate. The module 204 is further included so that the light initiation reaction of the maintenance member 3 by the LED light source is performed in advance.

In addition, as another example, the curing means 20 is a main body 200 installed inside the body portion 22 of the moving tool 2 as shown in FIG. 6B, and the inner periphery of the branch pipe 1 to be repaired In addition to the LED lamp 201 mounted on the main body 200 so that the LED light source is irradiated toward the inner side of the maintenance target branch pipe 1 from the rear relative to the LED lamp 201 in the main body 200 It may further include a hot air ejection unit 205 mounted to eject the hot air toward the periphery.

That is, in the present embodiment, after the photo-initiation reaction of the curable resin 310 is performed in advance by the LED light source, the curable resin 310 is thermally cured by the hot air of the hot air blowing unit 205.

In the case of this embodiment as well, the curing means 20 may include a control module 204, and the control module 204 selectively operates the LED lamp 201 and the hot air blowing unit 205, After operating the LED lamp 201 in advance with a set time difference, the hot air blowing unit 205 is controlled to operate so that the light initiation reaction and the thermal curing reaction of the maintenance member 3 can be sequentially performed.

Meanwhile, another embodiment for thermally curing the repair member 3 is shown in FIG. 6C. In the curing means 20 of this embodiment, instead of the hot air blowing unit 205 of the previous embodiment, It may further include a heating unit 206 mounted so that heat is applied toward the inner periphery of the tube (1).

In this case, the heating unit 206 may be any one of a heating coil or a heating plate mounted along the outer periphery of the main body 200 and heated by operating on an external input power source.

As described above, in the present invention, the LED lamp 201, which has excellent durability and can relatively minimize energy use, is installed in the front so that the curing of the repair member 3 proceeds in advance according to the light initiation reaction, and then at the rear. By installing a different type of heat or light irradiation device such as a UV lamp 203, the maintenance member 3 is configured so that the heat curing or light curing can be completed continuously.

Accordingly, it is possible to minimize the proportion of energy used for the operation of UV lamps, and as a result, energy use can be significantly reduced compared to the existing repair and reinforcement methods that use the existing UV lamps or hot air alone in operating the device. The effects that can be made can be derived.

Hereinafter, a branch pipe repair and reinforcement method of the present invention will be described with reference to FIG. 7.

In the step S20, the moving port 2 is moved while the maintenance member 3 is placed in the protruding packer 220-2 of the “T”-shaped packer 220 in the moving port 2.

At this time, the moving port 2 moves the protruding packer 220-2 of the “T”-shaped packer 220 to a position where the branch pipe 1 can be inserted, so that the “T”-shaped packer 220 During the expansion process of the "T"-shaped packer 220, the repair member 3 installed on the protruding packer 220-2 can be inserted into the branch pipe 1 to be repaired.

And in the step S30, by operating the air injection means 21 provided inside the body part 22 of the moving port 2 to expand the "T"-shaped packer 220, such a "T"-shaped packer The repair member 3 is in close contact with the branch pipe 1 to be repaired due to the pressure caused by expansion of 220, and the repair member 3 by the adhesive impregnated resin contained in the curable resin 310 of the repair member 3 (3) The attachment is made in close contact with the branch pipe 1 to be repaired.

In the step S40, the LED lamp 201 of the curing means 20 provided on the body 220 is operated in a state in which the repair member 3 is attached to the branch pipe 1 to be repaired, thereby leading to the LED light source.
