Description

절곡부가 구비된 각관 보수용 라이닝재 및 이의 제조방법{Lining pad with bending portion for maintenance of polygonal pipe and manufacturing method of the same}Lining material for repairing a rectangular pipe having a bent portion and a manufacturing method thereof

본 발명은 절곡부가 구비된 각관 보수용 라이닝재 및 이의 제조방법에 관한 것으로서, 더욱 상세하게는 부착대상 각관의 내측면 모서리에 대응되는 수지흡착재의 위치를 절곡한 후 상기 절곡부에 인접하게 바느질을 함으로써 재봉선을 따라 수지흡착재가 용이하게 절곡되어 각관의 내측면 모서리에 들뜸이 없이 부착되도록 한 절곡부가 구비된 각관 보수용 라이닝재 및 이의 제조방법에 관한 것이다.The present invention relates to a lining material for repairing a square tube having a bent part and a manufacturing method thereof, and more particularly, after bending the position of the resin absorbent corresponding to the inner side edge of the square tube to be attached, sewing is performed adjacent to the bent part. The present invention relates to a lining material for repairing a square tube having a bent part so that the resin absorbent material is easily bent along a seam line and attached to the edge of the inner surface of the square tube without lifting, and a method for manufacturing the same.

일반적으로 암거는 하수도관, 배수관, 농업용수관, 취수관 등으로 땅 속에 매설되어 사용되고 있다. 이러한 암거는 시공비용을 절감하기 위하여 공장에서 일정한 단위 길이로 대량 생산되어 현장으로 옮겨져 연결 설치된다.In general, the culvert is used as a sewer pipe, a drain pipe, an agricultural water pipe, an intake pipe, etc. buried in the ground. In order to reduce construction costs, these culverts are mass-produced in a certain unit length at a factory, moved to the site, and connected and installed.

도 1은 종래 암거로 사용되는 각관의 사시도이다.1 is a perspective view of a gak tube used as a conventional culvert.

땅 속에 매설된 하수관등의 관로가 노후화된 경우, 상기 관로를 땅 속에서 파내지 않고 그 내주면에 라이닝을 실시하여 상기 관로를 보수하는 관 라이닝 공법이 널리 사용되고 있다.When a pipeline such as a sewage pipe buried in the ground is old, a pipe lining method of repairing the pipe by lining the inner circumferential surface without digging the pipe in the ground is widely used.

즉, 상기 관 라이닝 공법은, 그 외주면이 기밀성이 높은 플라스틱필름으로 피복된 가요성의 관형상의 수지흡착재에 미경화의 경화성수지를 함침시켜 이루어진 관 라이닝재를 유체압에 의해서 관로 내에 반전시키면서 삽입함과 동시에, 관로의 내주면에 상기 관 라이닝재를 압압하여, 그 상태를 유지한 채로 관 라이닝재를 가열하여 이것에 함침된 경화성수지를 경화시킴으로써 관로의 내주면에 라이닝을 실시하는 공법이다.That is, in the pipe lining method, the pipe lining material made by impregnating an uncured curable resin into a flexible tubular resin absorbent whose outer circumferential surface is coated with a highly airtight plastic film is inserted into the pipe while inverting by fluid pressure. At the same time, it is a method of lining the inner circumferential surface of the pipe by pressing the pipe lining material on the inner circumferential surface of the pipe and heating the pipe lining material while maintaining the state to harden the curable resin impregnated therein.

도 2는 종래 각관에 라이닝재가 부착된 상태의 단면도이다.2 is a cross-sectional view of a state in which a lining material is attached to a conventional square tube.

원형관에 라이닝재가 부착되는 경우에는 라이닝재가 원형관의 내측에 들뜸이 없이 부착된다.When the lining material is attached to the round tube, the lining material is attached to the inside of the round tube without lifting.

그러나, 도 2에 도시된 바와 같이, 각관에 라이닝재가 부착될 경우에는 각관의 내측면 모서리에서 들뜸이 발생하게 된다.However, as shown in FIG. 2, when the lining material is attached to the square tube, lifting occurs at the edge of the inner surface of the square tube.

각관의 내측면 모서리에서 라이닝재는 자체 굽힘 복원력에 의해 평판 형태로 복원되고자 하므로, 초기에는 경화된 수지에 의해 모서리에 부착되더라도 시간의 경과에 따라 모서리 부위가 들뜨게 된다. Since the lining material at the edge of the inner surface of the square tube is restored in the form of a flat plate by its own bending restoring force, even if it is initially attached to the edge by the cured resin, the edge part is lifted over time.

결국 라이닝재가 각관의 내측면으로부터 탈락되어 보수재로서의 역할을 하지 못하게 되는 것이다.As a result, the lining material is removed from the inner surface of the square tube and thus does not function as a repair material.

따라서 다양한 형상의 각관 모서리에서 들뜸이 발생하지 않음과 동시에 경제적으로 제작이 가능한 라이닝재의 개발이 절실히 요청된다.Therefore, it is urgently required to develop a lining material that can be manufactured economically while not lifting at the corners of various shapes of square pipes.

도 3은 다양한 형상의 각관(100)에 대한 단면도이다.3 is a cross-sectional view of the square tube 100 of various shapes.

도 3에 도시된 바와 같이, 암거로 다양한 형태의 각관(100)이 사용되고 있다. 물론 헌치(haunch)가 형성된 정사각형 또는 직사각형 각관(100)이 가장 많이 사용되나, 지형의 형태나 특수 목적으로 오각형, 마름모 형상 등의 각관(100)도 사용되고 있다.As shown in FIG. 3 , various types of square tubes 100 are used as culverts. Of course, a square or rectangular square tube 100 having a haunch is most often used, but a square tube 100 such as a pentagonal shape or a rhombus shape is also used for the shape of the terrain or for a special purpose.

각관(100)의 보수에 사용되는 라이닝재(300)는 평판 형태의 라이닝재(300)를 파이프 형태로 말아서 사용한다. 따라서 원형 단면의 각관(100)에는 라이닝재(300)가 들뜨지 않고 잘 부착이 된다.The lining material 300 used for the repair of the square tube 100 is used by rolling the lining material 300 in the form of a flat plate in the form of a pipe. Therefore, the lining material 300 is well attached to the square tube 100 of the circular cross section without lifting.

그러나, 각관(100)에 부착되는 라이닝재(300)는 각관(100)의 내측면 모서리에서 들뜸이 발생하게 된다.However, the lining material 300 attached to the square tube 100 is lifted from the inner side edge of the square tube 100 .

종래에는 접착제나 실리콘을 각관(100) 모서리 부위에 주입하여 라이닝재(300)의 들뜸을 방지하고 있으나, 시간이 경과되면 결국 모서리 부위에서 라이닝재(300)가 들뜨게 된다.Conventionally, an adhesive or silicone is injected into the corner portion of the square tube 100 to prevent lifting of the lining material 300 , but as time elapses, the lining material 300 is lifted from the corner portion in the end.

이에, 본 발명에서는 각관(100)의 보수를 위해 부착되는 라이닝재(300)가 모서리 부위에서 들뜨지 않는 새로운 구조의 라이닝재(300)를 개발하게 되었다.Accordingly, in the present invention, a lining material 300 of a new structure in which the lining material 300 to be attached for repair of the square tube 100 does not rise at the edge portion has been developed.

도 4 내지 도 9를 참조하여 설명한다.It will be described with reference to FIGS. 4 to 9 .

본 발명에 따른 각관(100) 보수용 라이닝재(300)의 제조방법은 재단단계(S10), 절곡선 제도단계(S20), 절곡부 재봉단계(S30), 단부 결합단계(S40), 수지함침단계(S50)를 포함한다.The manufacturing method of the lining material 300 for repairing the square pipe 100 according to the present invention is a cutting step (S10), a bending line drafting step (S20), a bending part sewing step (S30), an end coupling step (S40), resin impregnation Step S50 is included.

재단단계(S10)는 수지흡착재(400)를 부착할 각관(100)의 내측면의 크기에 맞게 수지흡착재(400)를 자르는 단계이다.The cutting step (S10) is a step of cutting the resin absorbent 400 to fit the size of the inner surface of the square tube 100 to which the resin absorbent 400 is to be attached.

도 7에 도시된 바와 같이, 통상적으로 수지흡착재(400)는 직사각형 형태로 잘라진다.As shown in FIG. 7 , the resin adsorbent 400 is typically cut in a rectangular shape.

다음으로는 절곡선 제도단계(S20)가 수행된다.Next, the bending line drafting step (S20) is performed.

본 발명에서는 각관(100) 모서리에서 수지흡착재(400)가 용이하게 절곡되도록 하기 위해, 부착대상 각관(100)의 내측면 모서리에 대응되는 재단된 수지흡착재(400)의 위치에 절곡선(600)을 도시한다.In the present invention, in order to allow the resin absorbent 400 to be easily bent at the corner of the square tube 100, a bending line 600 at the position of the cut resin absorbent 400 corresponding to the inner side edge of the square tube 100 to be attached. shows

도 8에 도시된 바와 같이, 절곡선(600)은 각관(100)의 길이방향으로 도시된다.As shown in FIG. 8 , the bending line 600 is shown in the longitudinal direction of the square tube 100 .

원단을 접어 바느질을 하게 되면 재봉선(700)을 따라 잘 접히는 점에 착안하여, 이를 수지흡착재(400)에 적용하였다.When the fabric is folded and sewn, it is applied to the resin absorbent 400 by paying attention to the point that it folds well along the sewing line 700 .

도 9에 도시된 바와 같이, 절곡부 재봉단계(S30)는 절곡선(600)을 따라 수지흡착재(400)를 접은 후, 상기 절곡선(600)에 인접하여 절곡선(600)과 평행하게 수지흡착재(400)에 바느질을 하는 단계이다.As shown in FIG. 9 , in the bending part sewing step ( S30 ), the resin absorbent 400 is folded along the bending line 600 , and then adjacent to the bending line 600 and the resin parallel to the bending line 600 . This is a step of sewing on the adsorbent 400 .

이 때 수지흡착재(400)를 접는 방향은 내측 방향 또는 외측 방향 모두 가능한다.In this case, the folding direction of the resin adsorbent 400 may be both inward and outward.

도 5(a)는 외측 방향으로 접은 경우이고, 도 5(b)는 내측 방향으로 접은 경우이다.Fig. 5(a) is a case in which it is folded in an outward direction, and Fig. 5(b) is a case in which it is folded in an inward direction.

바람직하게는 내측 방향으로 접은 후 바느질을 하게 되면, 각관(100) 내측면에 부착되는 수지흡착재(400)의 표면에 단차가 형성되지 않아 밀착력을 높일 수 있다.Preferably, when sewing is performed after folding in the inner direction, a step is not formed on the surface of the resin adsorbent 400 attached to the inner surface of the square tube 100, so that adhesion can be increased.

절곡부 재봉단계(S30)를 통해 수지흡착재(400)에 형성된 재봉선(700)을 따라 수지흡착재(400)가 용이하게 절곡되므로, 각관(100)의 내측면 모서리에 들뜸이 없이 부착이 가능하게 된다.Since the resin absorbent 400 is easily bent along the sewing line 700 formed on the resin absorbent 400 through the bending part sewing step (S30), it is possible to attach it to the inner side edge of the square tube 100 without lifting. .

단부 결합단계(S40)는 수지흡착재(400)가 파이프 형상을 이루도록 수지흡착재(400)의 양측 단부를 연결하는 단계이다.The end coupling step (S40) is a step of connecting both ends of the resin adsorbent 400 so that the resin adsorbent 400 forms a pipe shape.

연결하는 방법으로는 바느질을 할 수도 있고, 접착제를 이용하여 연결할 수도 있다.As a connection method, you can sew or use an adhesive to connect.

마지막으로 수지함침단계(S50)가 수행된다.Finally, the resin impregnation step (S50) is performed.

수지함침단계(S50)는 수지흡착재(400)에 미경화 상태의 수지를 함침시키는 단계이다.The resin impregnation step (S50) is a step of impregnating the resin adsorbent 400 in an uncured state.

수지가 함침된 수지흡착재(400)를 각관(100) 내측면에 밀착한 상태에서 스팀을 주입하면 수지가 부풀어 오르면서 경화되어 각관(100)의 내측면에 고정된다.When steam is injected while the resin-impregnated resin absorbent 400 is in close contact with the inner surface of the square tube 100 , the resin swells and hardens and is fixed to the inner surface of the square tube 100 .
