BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

Hereinafter, piping constructed by the unreduced water supply and drainage repair method of the present invention will be described in detail with reference to FIGS. 1 and 2. FIG. Here, FIG. 1 is a perspective view of a pipeline constructed by the unreduced water supply and drainage repair method of the present invention, and FIG. 2 is a sectional view taken along line II-II 'of FIG.

In the unreinforced water supply and sewer repairing method applied to the present invention, a liner (L) including a nonwoven fabric impregnated with resin is inserted into a piping 20 to be repaired and cured to form the inside of the piping 20 And is reinforced with the liner (L) to repair the broken pipe (20).

Referring to FIGS. 1 and 2, a liner L is inserted into the inner side of the broken pipe 20. The liner L serves to prevent fluid such as sewage, water, and gas from flowing out of the piping 20 through the broken portion 25 of the piping 20 and to prevent foreign matter from flowing into the piping 20 . The liner L includes a nonwoven fabric P impregnated with a resin and a vinyl C surrounding the outer side of the nonwoven fabric P. Specifically, a liquid resin is impregnated into the double-folded nonwoven fabric (P). The inner tube of the pipe 20 is formed by covering the outer surface of the nonwoven fabric P impregnated with the resin with the vinyl C and inserting it into the pipe 20 and then hardening the resin.

The vinyl C covers the nonwoven fabric P when the air is filled in the nonwoven fabric P and the nonwoven fabric P expands. That is, the cover surrounding the nonwoven fabric P is not limited to the vinyl (C), and various materials such as polypropylene and polystyrene which can be used as the covering material of the nonwoven fabric P may be used. Particularly, it is possible to use a cover formed of a heat insulating material so that the resin can be cured even at a very low temperature depending on the construction environment.

The unreinforced type water and sewage repairing method using the manifold 90 used for expanding and hardening the liner L and the liner L will be described later in detail.

3 to 7, there is shown schematically the operation of the unreduced water and sewage repairing method according to the present invention.

First, as a preliminary preparation process for repairing the piping 20, the inside of the piping 20 is irradiated to confirm whether or not the piping 20 is damaged, and a repair position is determined. As a method of irradiating the interior of the piping 20, a robot equipped with an endoscope or a camera may be inserted to visually confirm a damaged part. The endoscope or the robot may be inserted through the manholes 40a and 40b, and if necessary, a part of the pipe 20 may be inserted and inserted.

If it is determined that the piping 20 needs to be repaired during the irradiation of the piping 20, the inside of the piping 20 may be cleaned for a repair work. Specifically, the upstream pipe 21 may be blocked by the water receiving apparatus 60 in order to prevent the introduction of water or sewage into the piping 20 to be operated. Then, the interior of the pipe 20 can be cleaned by spraying high-pressure cleaning water into the pipe 20 using a high-pressure injector or the like. The inside of the pipe 20 can be cleanly cleaned by sucking foreign substances or sediments together with the spraying of the washing water by the high-pressure injector.

In addition, it is possible to remove obstacles that may interfere with the operation of the inside of the piping 20 for repairing the piping 20. Here, the obstacle obstructing the work means that the protruding portion of the branch pipe 30 protrudes into the inside of the pipe 20 to form the concave and convex on the inner surface of the pipe 20. In order to insert the liner (refer to L in FIG. 1) into the pipe 20, it must be maintained uniformly on the inner surface. At this time, the operation of removing the obstacle can be changed depending on the diameter of the pipe 20. That is, the maintenance of the piping 20 having a diameter enough for the operator to directly enter can be performed by the operator, and the diameter can not be entered by the operator, or the internal environment is dangerous. If there is no robot, the work robot can be used. A cutting tool may be attached to the work robot to remove any obstacle inside the pipe 20.

Then, the liner L for repairing the pipe 20 can be manufactured in the field, and the previously prepared liner L can be supplied. If the length or width of the liner L required in the course of the above-described piping 20 irradiation is determined, the liner L may be directly manufactured in the form of a fitting in the field. At this time, the liner (L) can be manufactured by using the liner manufacturing apparatus (10). The liner manufacturing apparatus 10 can be used by being mounted on a moving means such as a vehicle, and can be used after being fixedly installed in the field. The liner L can be manufactured immediately before insertion into the pipe 20 in consideration of the pot life of the resin. The manufactured liner (L) can be bound to the manifold (90).

Referring to FIG. 4, the liner L is inserted into the pipe 20. The liner L may be inserted into the pipe 20 by the retractor 50 connected to the manifold 90 but the liner L may be inserted directly into the pipe 20 in the state where the manifold 90 is not fastened, Can be fixed to the retractor (50) and pulled into the underground pipe (20). The liner L previously manufactured in the field can be connected to the retractor 50 and inserted into the pipe 20 but the liner manufacturing equipment 10 is installed on the site so that the pipe 20 ). ≪ / RTI > That is, the liner L is manufactured in the apparatus for manufacturing a liner L and is directly connected to the manifold 90 and / or the retractor 50 without being taken up by a separate collecting unit (not shown) ). ≪ / RTI > In this way, the working time can be shortened.

4, the retractor 50 further includes a camera module 52 for monitoring the inside of the pipe 20 and the movement of the liner L from the outside, and the camera module 52 The picked-up image can be transmitted to the external monitor device 71.

That is, the retractor 50, which is coupled with one end of the liner L and moves the liner L to a predetermined position inside the pipe, is inserted into the repair section, and the retractor 50 Can be controlled.

The retractor 50 is connected to a driving means such as a winch 72 disposed inside or outside the pipe 20 by connecting means such as a wire, so that the moving direction and the moving speed can be controlled.

The winch 72 and the monitor device 71 may be integrally formed as shown in the figure but the present invention is not limited thereto and the winch 72 can be controlled by an operator who controls the winch 72, (72) may be arranged close to the monitor device (71).

5, when the liner L is inserted into a predetermined pipe 20, the manifold 90 is connected to both ends of the liner L, and compressed air is injected through the manifold 90 The liner L is expanded. At this time, the air injected into the liner L expands the liner L to closely contact the liner L inside the pipe 20, and keeps the liner L in the same shape as the pipe 20. When the low temperature curable resin is used for the liner L, the resin impregnated in the nonwoven fabric may be first cured by injecting air at room temperature into the liner L. At this time, the manifold 90 may be connected to one end of the liner L.

For example compressed air, distributed by the distributor 2000 into the liner L through the manifold 90 fastened to both ends of the liner L. [ In this process, before the fluid dispensed by the distributor 2000 is injected into the liner L through the manifold 90, the temperature, pressure, and the like are checked. A check valve 2100 may be provided to check the condition and selectively block the supply of fluid.

The expanded liner L may then be maintained for a period of time to cure the resin contained in the liner (L). The curing time of the resin may vary depending on the thickness and diameter of the liner (L), and the time until the curing is performed may vary depending on the composition ratio of the materials contained in the resin. The curing may be performed at a temperature of 100 to 180 ° C, and may be a method of injecting high temperature steam into the liner L through the manifold 90.

When the high-temperature steam is injected through the manifold 90 provided on both sides of the liner L, the fluid circulates in a certain direction in the liner L as shown in FIG. 7, (L) is gradually cured, and the curing operation can be completed by repeating the fluid circulation for a predetermined time.
