Description

TECHNICAL FIELD The present invention relates to an impregnating apparatus for impregnating a repair material, a method of impregnating the impregnant,

The present invention relates to a repair material impregnating device, and more particularly, to a repair material impregnating device and impregnating method capable of impregnating a repairing material used for partial repair of a pipe with a resin material in a very uniform and quick manner, To a partial repair method of the present invention.

In general, buried underground pipes such as water pipes, sewer pipes, gas pipes, communication pipes, and the like are damaged due to structural deterioration, subsidence of underground ground, earth pressure fluctuation on the ground, cracks and breakage due to external load, The wastewater of the wastewater is permeated underground through the cracks and broken parts to pollute the soil and erosion of the ground, so that the maintenance of the underground channel is frequently required.

Various methods are used to repair such damaged underground pipelines, and they are appropriately selected according to the characteristics and conditions of the damaged area. In this case, in case of a relatively small sewer pipe, a worker can not enter the sewer pipe, and therefore a grouting method or a lining method is usually used.

The grouting method is a method of spraying a predetermined liquid repair material from a repair device to a damaged area and then hardening the material to repair the damaged portion of the local pipeline, It is a public law. However, in the grouting method, the liquid repair material escapes to the damaged area of the pipeline and is mixed and absorbed into the soil around the pipeline. The waterproofing index function is effective as time elapses, but the repair material is lined on the inner wall of the pipeline The reinforcement function is uncertain.

The lining method is used when the damage is severe and additional reinforcement is needed. If grouting is not possible due to the damaged part of the pipeline or the entire inner side of the pipeline, it is necessary to use a separate repair material (lining material) It is a method to reinforce a wide range of damaged parts by attaching, and it is done by a sewer line part repair device called a packer.

Such a lining method is mainly applied to a partial repair method of a pipeline. In the partial repair method of the pipeline, an expansion member made of a rubber material is placed on the outer circumferential surface of a hollow frame, and a repair material (e.g., a hardening agent and a resin- , Felt, and the like) is wrapped and then moved to the damaged position, and compressed air is applied to the expansion member to expand the repair material to adhere to the inner wall of the sewage pipe.

On the other hand, in the partial repair method of pipelines, the impregnation method of the repair material impregnating the liquid resin into the repair material is mainly applied in the field.

In the impregnating method of a repair material which is performed in the field, a liquid resin mixed with a hardening agent is spread on the surface of the repair material by using a brush or the like in a state where the sheet-like repair material is spread before the repair material is wrapped on the expanding member.

As described above, since the conventional method of impregnating the repair material is performed by applying the liquid resin on the surface of the repair material, the resin is not uniformly impregnated over the entire surface of the repair material, and the repair quality thereof is greatly deteriorated.

In addition, since the curing agent used in the repairing material can be cured within 1 hour as a room temperature curing agent, partial repairing method should be completed within 1 hour after the resin is impregnated into the repairing material, but it takes a long time to apply the liquid resin to the repairing material, There is a disadvantage that the construction method can not be smoothly performed.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. For the sake of convenience, the size, line thickness, and the like of the components shown in the drawings referenced in the description of the present invention may be exaggerated somewhat. The terms used in the description of the present invention are defined in consideration of the functions of the present invention, and thus may be changed depending on the user, the intention of the operator, customs, and the like. Therefore, the definition of this term should be based on the contents of this specification as a whole.

1 and 5 are views showing a repair material impregnating apparatus according to an embodiment of the present invention.

1 and 5, a repairing material impregnating apparatus according to the present invention comprises a container 10 having a receiving space for receiving a liquid resin and a repairing material, and a container 10 detachably connected to the container 10, And a vacuum inhaler 51 for applying a vacuum suction force to the space.

The container 10 has an accommodation space in which the maintenance material 1 and the liquid resin can be accommodated, as shown in Fig. The container 10 is made of a flexible material such as a plastic pack and can be easily contracted when a vacuum suction force of the vacuum inhaler 51 is applied thereto.

Here, the repairing material 1 is made of a porous material such as a fabric such as a nonwoven fabric, a felt and the like, and glass fiber, aramid, carbon fiber and the like.

A closure part 11 is formed at the lower end of the container 10 and an opening 12 is formed at the upper end of the container 10. Through this opening 12, the maintenance material 1 and the liquid resin can be easily accommodated in the accommodating space in the container 10.

Particularly, the repairing material 1 accommodated in the housing space of the container 10 is in the form of a sheet (see Fig. 19 (a)). By stacking the repairing materials 1 in multiple layers, It can be easily accommodated. Accordingly, the size of the container 10 does not need to be matched to the width or length of the repairing material 1, so that it can be made very compact. By using the container 10 having such a compact size, the impregnation of the repair material can be carried out easily and easily at the maintenance site of the pipeline.

In addition, the sealing portion 13 may be formed on the upper portion of the container 10 adjacent to the opening 12, and the sealing portion 13 may have a re-openable structure.

According to one embodiment, the seal 13 may be composed of zipper strips having a female zipper profile 13a and a male zipper profile 13b that are releasably engaged . As described above, not only the opening and closing of the opening 12 can be simplified through the sealing portion 13 made of the zipper strip structure, but also the sealing property can be ensured when the opening 12 is closed.

As shown in Figs. 1 and 2, the repairing material 1 has a plurality of folded portions 1a, as the repairing material 1 is folded into the accommodating space of the container 10 in multiple folds.

After the maintenance material 1 is accommodated in the accommodating space of the container 10, the liquid resin 3 is introduced into the accommodating space of the container 10. [ Here, the liquid resin 3 is mixed with a room temperature curing agent.

At this time, since the maintenance material 1 accommodated in the accommodating space of the container 10 has a plurality of folded portions 1a, when the liquid resin 3 is put into one of the two, the plurality of folded portions 1a, There is a possibility that the resin 3 may not be uniformly dispersed in the accommodating space of the container 10. In order to cope with this, as shown in Fig. 2, the liquid resin 3 is uniformly injected into the accommodating space of the container 10 by using the injector 20.

2, the injector 20 according to the present invention includes a manifold 21 in which a liquid resin mixed with a room temperature hardener is temporarily stored, a plurality of injection pipes 22). It is preferable that the plurality of injection pipes 22 are spaced apart corresponding to the interval between the folded portions 1a of the repair material 1. [ The number of the inlet pipes 22 may be more than one more than the number of the folded portions 1a of the repairing material 1, thereby making it easier to uniformly inject the liquid resin.

2, the manifold 21 of the dispenser 20 is placed on the side of the opening 12 of the container 10, as shown in FIG. 2, when the liquid resin is introduced into the receiving space of the container 10 through the dispenser 20. The injection pipes 22 of the dispenser 20 are disposed in the upper portion of the inside of the container 10 so that the liquid resin is uniformly injected into the container space of the container 10 through the plurality of injection pipes 22 .

Since the liquid resin can be injected through the plurality of injection pipes 22 in correspondence with the folded portion 1a of the maintenance material 1 accommodated in the accommodating space of the container 10, And when the vacuum suction force of the vacuum inhalers 51 and 52 is applied as described later, the uniformly dispersed liquid resin can be uniformly impregnated throughout the repairing material 1. [

The vacuum inhaler 51 is connected to one side of the container 10 in which the maintenance material 1 and the liquid resin 3 are accommodated and is configured to apply a vacuum suction force to the accommodation space of the container 10.

The vacuum inhaler 51 connected to the container 10 according to the first embodiment is constituted by a vacuum sealer or the like as shown in Fig. 5 so as to seal the entire opening 12 of the container 10 The liquid resin and the air or the like move toward the opening 12 and / or the vacuum inhaler 51 in the accommodating space of the container 10 by applying a vacuum suction force to the accommodating space of the container 10 ) Can be uniformly impregnated throughout the repairing material (1). In the case where the vacuum inhaler 51 is constituted by a vacuum sealer and seals the entire opening 12 of the container 10, the sealing portion 13 described above may be omitted.

On the other hand, when the liquid resin moves by the vacuum suction force and flows into the vacuum inhaler 51 through the opening 12, the failure of the vacuum inhaler 51 is likely to occur, so that the liquid resin flows into the vacuum inhaler 51 A configuration for blocking the "

 As described above, when the liquid resin moves by the vacuum suction force, the protector 15 for blocking the liquid resin from entering the vacuum inhaler 51 is positioned adjacent to the opening 12 of the container 10, 15 may be arranged to extend transversely across the width of the vessel 10. [

6, the protector 15 is made of an absorbent material capable of reliably absorbing a liquid component such as a nonwoven fabric, and the container 10 is contracted by the vacuum suction force of the vacuum inhaler 51 And thus extend across the upper portion of the container 10 in the width direction. As the protector 15 is disposed horizontally across the upper portion of the container 10, the liquid resin (see arrow K in FIGS. 5 and 6) moving by the vacuum suction force is absorbed by the protector 15, The movement of the liquid resin to the opening 12 side of the container 10 is blocked, so that the liquid resin or the like can be surely prevented from flowing into the vacuum inhaler 51.

1, one or more guide grooves 17 may be formed on the inner wall of the container 10 to facilitate movement of the liquid resin and air during vacuum suction. The guide groove 17 may be formed along the longitudinal direction of the container 10 as shown in FIG. 1, or may be formed in various other lattice-like structures.

In particular, it is preferable that the upper end of the guide groove 17 is formed so as to be spaced apart from the opening 12 of the container 10 or the protector 15. This is to prevent the liquid resin from being excessively moved toward the upper end of the container 10 or the protector 15 side by the guide groove 17 so as to prevent the liquid resin from flowing into the vacuum inhaler 51 in advance.

3 and 4, the present invention further includes a mesh bag 50 in which a repair material 1 is accommodated. The mesh bag 50 is made of a mesh of a predetermined mesh, 50 after the maintenance material 1 is inserted into the accommodating space of the container 10.

When the repair material 1 is inserted into the mesh bag 50, the liquid resin can move along the mesh of the mesh bag 50 at the time of vacuum suction, and the mesh bag 50 guides the movement of the liquid resin So that the liquid resin can be quickly and uniformly impregnated into the repairing material (1).

Particularly, the mesh bag 50 is made of a material which does not absorb the liquid resin, and the liquid resin can move very smoothly along the mesh of the mesh bag 50, so that the impregnation of the maintenance material 1 proceeds very stably .

3, the repair material 1 may be inserted into the mesh bag 50. Alternatively, the repair material 1 may be wound into a cylindrical shape as shown in FIG. 4 and inserted into the mesh bag 50 .

When the repair material 1 is inserted into the mesh bag 50, the guide groove 17 may not be formed on the inner wall of the container 10 as shown in FIGS.

7 shows a container 10 according to a second embodiment of the present invention and is provided with a connection port 14 to which a vacuum inhaler 52 is connected at one side adjacent to the opening 12 of the container 10 .

The vacuum inhaler 52 according to the second embodiment is constituted by a hand type vacuum inhaler having a relatively small size and the suction port of the vacuum inhaler 52 is directly connected to the connection port 14 or through the connection hose 52a or the like And can be connected to the connection port 14.

A thin film type check valve is provided in the connection port 14. When the vacuum suction force of the vacuum suction device 52 is not applied, the thin film type check valve is operated to close the accommodating space and the external space of the container 10, When the vacuum suction force of the suction device 52 is applied, the vacuum suction force is applied to open the vacuum device.

With this configuration, after the maintenance member 1 and the liquid resin or the like are received in the receiving space of the container 10, the upper end of the container 10 is surely sealed through the sealing portion 13, And the vacuum inhaler 52 is connected. Thereafter, the vacuum inhaler 52 is driven to move the liquid resin or the like toward the connection port 14 and / or the vacuum inhaler 52 by the vacuum suction force, and the liquid resin is spread over the entire surface of the repair material 1 It can be uniformly impregnated.

The rest of the configuration and operation are the same as those of the preceding embodiment, and a detailed description thereof will be omitted.

8 is a view showing a container 10 according to a third embodiment of the present invention in which a connection port 14 is positioned on one side of an upper side of the container 10 and is arranged to surround the periphery of such connection port 14 The protector 15 is formed in an "L" In other words, by implementing a structure that surrounds the periphery of the connection port 14 without having to arrange the protector 15 horizontally on the upper part of the container 10, the liquid resin moving toward the connection port 14 by the vacuum suction force So that the liquid resin can be prevented from flowing into the connection port 14 and / or the vacuum sucker 52, and the material of the protector 15 can be saved.

The rest of the configuration and operation are the same as those of the preceding embodiments, so a detailed description will be omitted.

9 is a view showing a container 10 according to a fourth embodiment of the present invention in which a connection port 14 is located at an upper middle portion of the container 10 and a protector 15 are formed in a "U "

The container 10 of the fourth embodiment can make the movement of the liquid resin more uniform by the vacuum suction force as the connection port 14 is located at the upper middle portion of the container 10. [

The rest of the configuration and operation are the same as those of the preceding embodiments, so a detailed description will be omitted.

Fig. 10 is a modified embodiment of the container 10 according to the first embodiment (Fig. 5), further comprising a valve unit 30 capable of imparting a vacuum release and an additional vacuum suction force to the container 10. Fig.

The valve unit 30 is provided on the inner wall surface of one side of the container 10 as shown in FIG. 15, and in particular, the valve unit 30 is arranged to be positioned on the upper side of the protector 15.

The valve unit 30 includes a valve body 31 attached to an inner wall surface of one side of the container 10, as shown in Figs.

The valve body 31 has a communicating portion 31a communicable with the outside of the container 10 as shown in Figs. 14 and 15 and a peripheral portion 31b surrounding the periphery of the communicating portion 31a. In particular, the valve body 31 may be made of a porous and soft material such as a nonwoven fabric.

The communication portion 31a may be made of a material (for example, a nonwoven fabric or the like) that can easily communicate with the outside of the container 10. Particularly, as shown in Fig. 16 (a), the communicating portion 31a can be penetrated by a punching tool 41 such as a punch or the like, and the communicating portion 31a is provided with a vacuum releasing mechanism, The through hole 33 for the through hole 33 can be easily formed.

A coating layer 32 made of polyethylene or the like is formed on one surface of the peripheral portion 31b and the coating layer 32 can be brought into contact with the inner surface of the container 10 as shown in FIG. One side of the peripheral portion 31b may have a flat surface by the coating layer 32 and the suction port of the vacuum inhaler 52 may be more tightly adhered through the coating layer 32. [

Thereby, after the primary vacuum suction force is applied through the opening 12 or the connection port 14 of the container 10 and the liquid resin is impregnated into the repair material 1, the liquid resin is uniformly supplied to the repair material 1 The vacuum is released from the accommodation space of the container 10 by the valve unit 30 and then the additional vacuum suction force is applied to the maintenance member 1 while the sealed state of the container 10 is maintained in the case where the container 10 is not impregnated. The impregnation state of the liquid resin can be corrected.

The vacuum release by the valve unit 30 and the application of the additional vacuum suction force will be described in more detail with reference to FIG.

Since the communicating portion 31a of the valve body 31 is made of a material such as a nonwoven fabric or the like, it can be easily penetrated by a perforating tool 41 such as an auger as shown in Fig. 16 (a) An opening 33 may be formed in the communicating portion 31a. Through this opening 33, it becomes possible to release the vacuum for the receiving space of the container 10 to which the vacuum suction force is applied primarily. Thereafter, by connecting the suction port of the vacuum suction device 52, an additional vacuum suction force can be applied through the opening 33, so that the impregnation degree of the liquid resin to the repair material 1 can be corrected.

After the liquid resin is uniformly impregnated into the repair material 1 as described above, the impregnation degree of the liquid resin to the repair material 1 is appropriately corrected, and then the liquid resin is placed on the opposite side of the valve body 31 as shown in Fig. 16 (c) A closing member 35 is attached to the outer surface of the container 10 so that the through hole 33 of the valve body 31 is blocked by the closing member 35 against the external space, Vacuum can be maintained against the space. The closure member 35 may be made of an adhesive member such as an adhesive tape coated with a pressure-sensitive adhesive on its back surface.

When the impregnation state of the liquid resin with respect to the repairing material 1 is not uniform or the liquid resin impregnation is incomplete after the vacuum suction force is applied through the opening 12 of the container 10 by the valve unit 30 It is possible to more effectively realize the total impregnation of the liquid resin with respect to the repairing material 1 by applying additional vacuum suction force after the vacuum in the container 10 is firstly released.
