Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for regenerating a sagittal tube,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for regenerating a fallen tube, and more particularly, to a method and apparatus for regenerating a fallen tube using a tube without removing a fallen tube by mounting a new tube inside the fallen tube.

Generally, casting pipes, steel pipes, synthetic pipes, and concrete pipes are used for conveying fluid such as a water pipe, a sewer pipe, an oil pipeline, and a gas pipe.

Among them, a large pipe mainly uses a cast iron pipe or a steel pipe. When a cast iron pipe or a steel pipe is used for a long time, it is aged due to fluid or other foreign matter passing through the inside of the pipe. Especially, in the case of a water supply pipe composed of a cast iron pipe or a steel pipe, the inside thereof is coated and prevented from being oxidized for supplying safe drinking water.

However, if it is used for a long time, the coating portion inside the pipe may be corroded or peeled off. In order to solve such a problem, there is a method of replacing the entire pipeline, but regeneration methods which are improved while the pipeline remains intact are applied. As a result, various research and development are under way to smoothly and efficiently perform pipeline rehabilitation work.

As an example, Korean Patent No. 863263 discloses an apparatus and method for rehabilitating a wreckage. The patented invention includes a main body having a plurality of branch tubes having a hollow hole for moving straight on the inner surface of the wastewater tube and for passing a hose for supplying fluid from the outside; A first absorber extending equiangularly from the outer side surface of each of the segments of the main body toward the channel surface and having a first absorber that is driven to expand and contract in correspondence to the pressure applied to the channel surface, Device; The main body of the main body is connected to the main body of the main body through a through hole for allowing the hose to pass through the central portion. A diversion joint for providing a flexible bendability at the passage of the bending portion; A rotating device connected to a center portion of the direction switching joint; A second absorber extending from the outer surface of the rear end side partition tube of the main body at an equal angle from the outer surface of the main body toward the channel surface and being in contact with the channel surface, A second moving device traveling on the uneven surface by the generated scale; A scale removing device extending in a radial direction of the pipe from a central axis of the rotary device and grasping a fine cutting line in a circumferential direction while rotating the end in contact with the pipe surface at a constant pressure; A channel polishing device installed in the radial direction on the central axis of the rotating device in place of the scale removing device and spraying the shot floss toward the inner surface of the channel whose scale has been removed by a subsequent process of the scale removing process to polish the inner surface of the channel; And a coating apparatus for replacing the pipe line polishing apparatus and radially installed on the center axis of the rotating apparatus and spraying the paint toward the inner surface of the pipe line which is polished by a subsequent step of the polishing step to form a lining. However, since the above-described regeneration method is simply a method of processing the inner surface of the throat tube, there is a problem in that it can not be applied to a case where cracks are generated or partially damaged in the throat tube.

A method of using a new pipe as a pipe by inserting a separate new pipe into the inside of the old pipe is proposed as it is, but a frictional force is greatly generated by simply pushing the new pipe. Therefore, There is a disadvantage that there are many difficulties to insert continuously. In addition, concrete must be installed between the new pipe and the old pipe so that the new pipe does not flow. The pneumatic pressure existing between the new pipe and the old pipe may cause a problem that the concrete pouring is not uniformly performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a rolled steel pipe regeneration apparatus and a rolled steel pipe regeneration method according to the present invention will be described in detail with reference to the accompanying drawings.

The method of regenerating a scutellum according to the present invention is a method of regenerating a scutellum tube that allows a fluid to flow inside a new tube by constructing a new tube inside a scratched tube in which cracks are formed or broken and simply pushing a new tube drawn into the inside of the scratched tube But it is constituted to lift the new pipe and move it by using a separate transportation car.

If the new pipe is pushed in the state of being seated in the old pipe, a large frictional force is generated between the new pipe and the old pipe, so that it is difficult to move the new pipe far away and the new pipe is damaged in the process of moving the new pipe There is also a drawback that there is concern. However, when the new pipe is lifted and moved as in the method of regenerating the old pipe according to the present invention, since the new pipe can be moved far away, it is possible to repair the old pipe in a longer section and friction between the new pipe and the old pipe is not generated. There is an advantage that no tube damage or breakage occurs.

Hereinafter, with reference to the accompanying drawings, a process of lifting and moving the new pipe using the transportation bogie as described above will be described.

FIGS. 1 and 2 illustrate a process of moving a new pipe using a rolled steel pipe recycling apparatus according to the present invention, and FIGS. 3 and 4 are a side view and a front view of a transportation car included in the present invention.

In order to install the new pipe 200 inside the old pipe 100 by the method of regenerating the old pipe 100 according to the present invention, as shown in FIG. 1, the ground is first excavated and a part of the upper pipe of the old pipe 100 is opened And the new pipe 200 is drawn into the waste pipe 100 by using the crane 300. At this time, since the outer diameter of the new pipe 200 is smaller than the inner diameter of the old pipe 100, it is possible to move the old pipe 200 in the longitudinal direction of the old pipe 100. The plurality of new pipes 200 supplied to the inside of the waste pipe 100 are lifted up by a transportation car 500 positioned to penetrate the interior of the new cargo pipe 200 as shown in FIG. They are arranged in a line by the car 400 frequently.

The conveying carriage 500 is formed to have a height and a width that can penetrate the inside of the new pipe 200 so as to stably lift the new pipe 200 in the old pipe 100, A body 510 which can move in the longitudinal direction of the wastewater pipe 100 and can pass through the inside of the new pipe 200 and a body 510 when the body 510 is extended inside the new pipe 200. [ The elevating block 530 is positioned between the upper surface of the new pipe 200 and the ceiling surface of the new pipe 200 and the elevating block 530 is raised or lowered so that the elevating block 530 lifts the new pipe 200 And an elevating cylinder 540. Therefore, if the elevator block 530 is raised by operating the elevator cylinder 540 after the new container pipe 200 is positioned over the center portion of the body 510, The new pipe 200 is not brought into contact with the old pipe 100 and is lifted up by the lifting block 530 so that the new pipe 200 is lifted up in the longitudinal direction of the old pipe 100 without friction with the old pipe 100 . Since the new pipe 200 extends between the front wheel 512 and the rear wheel 514 provided at the lower side of the body 510, even if the lift block 530 lifts the new pipe 200, the front wheel 512 And the rear wheel 514 can be kept in contact with the bottom surface of the throat pipe 100. Therefore, the conveying carriage 500 can be moved in the longitudinal direction of the waste pipe 100 while the new pipe 200 is lifted.

On the other hand, the transporting carriage 500 has a function of lifting the new pipe 200, and there is no driving capability of itself, so that it is moved by a separate freight car. At this time, a connecting portion 520 is provided at the rear end side of the body 510 so as to be connected to the car. Since the structure in which the non-powered vehicle and the motor vehicle are connected to each other is already widely used in the related art, A detailed description thereof will be omitted.

5 and 6 are longitudinal sectional views showing a process of installing a new pipe 200 inside the waste pipe 100. FIGS. 7 and 8 are views showing a concrete pouring unit 600 and an anti- 700 are mounted on the new pipe 200. As shown in Fig.

5, the new pipe 200 supplied to the inside of the old pipe 100 is inserted into another new pipe 200 (the right pipe 200 in FIG. 5) into which the leading end (left end in FIG. 5) (The right end in Fig. 5), and then integrally connected. At this time, between the two new pipes 200 arranged so as to prevent the fluid flowing inside the new pipe 200 from flowing out through the connection part 520, it is necessary to completely seal the new pipe 200, It is preferable that the entire mutually abutting portion is connected so as to be closed. When the new pipe 200 is made of metal, it is preferable that the new pipe 200 is connected by a coupling method such as welding. When the new pipe 200 is made of plastic and can not be welded, It is preferable that they are integrally connected. Of course, any joining method may be applied as long as it is possible to connect the new pipe 200, which is arranged successively in addition to the above-mentioned welding, adhesion and fusion, so that the inside and outside of the new pipe 200 are isolated.

Since the outer diameter of the new pipe 200 is made smaller than the inner diameter of the old pipe 100, the new pipe 200 can be swung vertically and horizontally inside the old pipe 100. Therefore, it is preferable to place the concrete between the new pipe 200 and the old pipe 100 to fix the new pipe 200 to the old pipe 100 after the plurality of new pipes 200 arranged in series are integrally connected Do.

5, when the plurality of new pipes 200 are arranged and connected in a row, the conveyance carriage 500, which has been drawn into the new pipe 200, is moved backward to the outside of the new pipe 200 The concrete pouring unit 600 is installed in the new pipe 200 and the concrete C is poured between the new pipe 200 and the old pipe 100 as shown in FIG. At this time, if the transporting carriage 500 lifting the new pipe 200 is directly retracted, the new pipe 200 is taken out together with the lifting cylinder 540. The lifting cylinder 540 is then lowered to descend the lifting block 530, 500).

7, the concrete pouring unit 600 for pouring the concrete C between the new pipe 200 and the old pipe 100 is formed on the rear end side (left side in FIG. 6) of the new pipe 200 And the end of which penetrates through the partition plate 610 and is inserted between the new pipe 200 and the old pipe 100, And an injection tube 620. Therefore, when the diaphragm 610 is coupled to the rear end of the new pipe 200 and then the concrete C is injected through the concrete injection pipe 620, the concrete C is filled only in the space inside the diaphragm 610, (610).

At this time, if only one concrete injection pipe 620 is provided, the concrete is sufficiently poured in a portion of the space between the new pipe 200 and the old pipe 100 adjacent to the concrete injection pipe 620, As shown in FIG. 7, the concrete injection pipe 620 is provided in a plurality of two or more as shown in FIG. 7, and each concrete injection pipe 620 is provided with a plurality of the concrete injection pipes 620, That is, the end positions of the respective concrete injection pipes 620 are different from each other. As shown in this embodiment, when the insertion distances of the end portions of the concrete injection pipes 620 are different from each other, the space between the new pipe 200 and the old pipe 100 is filled with the concrete as a whole, There is an advantage that the strength can be formed to be the same.

In addition, when the concrete injection pipe 620 is taken out after completing the concrete injection, an empty space is formed at the position where the concrete injection pipe 620 is located. Therefore, when the concrete is injected through the concrete injection pipe 620, It is preferable that the concrete injection pipe 620 is gradually drawn out to the outside. When the concrete is injected while drawing the concrete injection pipe 620 in this way, the entire space between the new pipe 200 and the old pipe 100 can be filled tightly with concrete without any void.

When the concrete C is installed in the space between the new pipe 200 and the old pipe 100 as described above, the new pipe 200 floats upward due to buoyancy of the concrete C, There arises a problem that the main body 200 can not be positioned at the center of the throat tube 100. Therefore, the regeneration apparatus according to the present invention is mounted on the outer surface of the new pipe 200, and the distance between the external surface of the new pipe 200 and the inner surface of the old pipe 100 is made constant The anti-floating band 700 may be additionally provided. 7 and 8, the upper portion of the outer surface of the new pipe 200 is surrounded by the upper portion of the flotage prevention band 700, and at least two protrusions (not shown) The new pipe 200 can not be lifted up even though concrete is poured between the new pipe 200 and the old pipe 100 and is maintained in a fixed state at the center of the old pipe 100 . At this time, the two or more protruding ends 710 are symmetrically disposed about the longitudinal central axis of the new pipe 200, as shown in FIG. 8, so that the new pipe 200 can be fixed without moving in the left- Is preferably arranged.

In this embodiment, only the upper portion of the outer surface of the new pipe 200 is covered by the above-mentioned flotage prevention band 700. However, the above-mentioned flotage prevention band 700 surrounds the entire outer surface of the new pipe 200 . In this case, when the float prevention band 700 covers only a part of the upper part of the new pipe 200, the new pipe 200 can be lowered to reach the bottom surface of the old pipe 100 before the concrete is poured. 200 may be additionally provided between the bottom surface of the main pipe 200 and the bottom surface of the old pipe 100 to support the new pipe 200.

On the other hand, an air layer may be formed between the new pipe 200 and the old pipe 100 while the concrete is being poured. If the air layer is present, the concrete is not poured tightly and the overall strength is weakened. It is preferable that the air discharge pipe 630 is inserted through the diaphragm 610. Also, in the process of pouring concrete, the water mixed in the concrete can be gathered in one place. Even when the physical components are gathered in this way, the concrete can not be filled between the new pipe 200 and the old pipe 100 It is preferable that a drain pipe 640 is also mounted on the diaphragm 610. At this time, the air is gathered to the upper side of the space between the new pipe 200 and the old pipe 100, and the water collects to the lower side of the space between the new pipe 200 and the old pipe 100, And the drain pipe 640 is installed so as to pass through the lower side of the diaphragm 610.

The end of the new pipe 200 is installed so as to pass through the intermediate side of the partition plate 610 so that the operator can visually confirm how normally the concrete laid between the new pipe 200 and the old pipe 100 is visually inspected. And a check pipe 650 for exposing the concrete pouring state between the waste pipe 100 and the waste pipe 100 to the outside.

The use of the regenerating apparatus for regenerating the waste tube 100 and the regenerating method for the waste tube 100 according to the present invention can provide a new tube 200 The construction period can be remarkably shortened and the concrete can be evenly laid over the entire space between the old pipe 100 and the new pipe 200 so that the overall strength of the pipe can be made higher and higher .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the present invention.
