It relates to a method of manufacturing a belt-shaped fiber reinforcement for retaining walls.

일반적으로 보강토 옹벽에서 옹벽블럭과 뒷채움흙을 결합시키는 보강재로서는 그물상으로 된 지오그리드(Geogrid) 등이 있으며, 최근에 와서는 보강토 옹벽의 전면에 조립식으로 구축되는 옹벽블럭들의 상면에 형성된 끼움홈에 끼워지면서 뒤채움흙에 지그재그상으로 설치되는 띠형 섬유보강재가 사용되고 있다.Generally, as a reinforcing material that combines the retaining wall block and the back filling soil in the reinforced soil retaining wall, there is a mesh-shaped Geogrid, and more recently, it is inserted into the fitting groove formed on the upper surface of the retaining wall blocks that are prefabricated in the front of the reinforced soil retaining wall. As it is built, a band-shaped fiber reinforcement is used that is installed in a zigzag shape on the backfilling soil.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 1은 본 발명의 기술인 내진 및 조립식 보강토 옹벽용 띠형 섬유보강재의 제조방법을 보여주는 제조공정도이고 도 2는 도 1의 제조방법에 의해 제조된 내진 및 조립식 보강토 옹벽용 띠형 섬유보강재의 구조를 보여주는 사시도로서 이에 따른 본 발명은 위사와 경사를 교차시켜 제직하는 코어부재 제조공정(S100)을 수행한다.1 is a manufacturing process diagram showing a method of manufacturing a belt-type fiber reinforcement for a seismic and prefabricated reinforced soil retaining wall, which is the technology of the present invention, and FIG. 2 is a structure of a belt-type fiber reinforcement for a seismic and prefabricated reinforced soil retaining wall manufactured by the manufacturing method of FIG. As a perspective view, according to the present invention, a core member manufacturing process (S100) of weaving by crossing the weft yarn and the warp yarn is performed.

이때 상기 코어부재(10)는 PE사, PP사, PET사, LCP사, 탄소섬유사, 유리섬유사 중 어느 하나를 사용하며 제직의 형태는 평직(Plane), 능직(Twill), 주자직(Satin) 중 어느 하나의 제직 형태를 사용하여 제조한다.At this time, the core member 10 is made of any one of PE yarn, PP yarn, PET yarn, LCP yarn, carbon fiber yarn, and glass fiber yarn, and the form of weaving is plain weave (Plane), twill weave (Twill), main weave ( It is manufactured using any one of the woven forms of Satin).

한편 코어부재(10)의 제직시 길이를 형성하는 쪽의 경사가 폭을 형성하는 위사보다 두께를 두껍게 형성하여 사용할 수도 있으며, 이때 길이 방향에 사용되는 경사의 두께를 두껍게 형성하는 이유는 길이 방향 쪽의 인장력을 더 높게 형성시키기 위함이며 인장력 조절도 용이한 이점이 있기 때문이다. On the other hand, when weaving the core member 10, the warp of the side forming the length may be formed to be thicker than the weft forming the width, and the reason for forming the thickness of the warp used in the longitudinal direction is thicker in the longitudinal direction. This is because it is to form a higher tensile force and has an advantage that it is easy to adjust the tensile force.

상기에서와 같이 코어부재(10)의 제조가 완료되면 상기 코어부재(10)를 보호부재를 형성시키는 보호부재 형성공정(S200)을 수행한다. 상기 보호부재 형성공정(S200)의 방법은 액체 상태의 수지가 저장되어 있는 저장통에 이송중인 코어부재(10)가 담기어졌다가 밖으로 다시 나오도록 통과시켜 제직된 코어부재(10)의 표면에 보호부재(20)가 형성되도록 하는 것이다.When the manufacturing of the core member 10 is completed as described above, a protective member forming process (S200) of forming a protective member for the core member 10 is performed. In the method of the protective member forming process (S200), the core member 10 being transported is contained in a storage container in which the liquid resin is stored, and then passed through it to come out again, and the protective member on the surface of the woven core member 10 (20) is to be formed.

상기 코어부재(10)의 표면에 코팅되는 수지의 종류로는 PE, PP, PET, HDPE PU, ABS, 고무 중 어느 하나를 사용한다. 상기 코어부재(10)의 표면에 보호부재(20)를 형성하는 수지가 저장통(30)을 통과하여 묻혀지면 한쌍의 로울러로 이루어진 두께조절수단(40)을 통과시켜 보호부재(20)의 두께를 조절하는 보호부재 두께조절공정(S300)을 수행한다.As the type of resin coated on the surface of the core member 10, any one of PE, PP, PET, HDPE PU, ABS, and rubber is used. When the resin forming the protective member 20 is buried on the surface of the core member 10 through the storage container 30, the thickness of the protective member 20 is reduced by passing through the thickness adjusting means 40 consisting of a pair of rollers. The protective member thickness control process (S300) to be adjusted is performed.

상기 보호부재 두께조절공정(S300)은 회전 가능하면서 고정 설치된 고정용 로울러와 미도시된 모터의 회전력이 전달되어 회전되며 상하로 이동이 가능한 이동로울러로 이루어진 구조이다. The protective member thickness control step (S300) is a structure consisting of a fixed roller that is rotatable and fixedly installed, and a moving roller that is rotated by transmitting a rotational force of a motor (not shown) and is movable up and down.

이때 상기 로울러에는 가로줄, 세로줄을 형성시켜 사각형 또는 마름모 형태의 홈을 형성시켜 코어부재가 표면 거칠기를 갖도록 형성시켜 미끄러짐을 방지하는 것이다.At this time, horizontal lines and vertical lines are formed in the roller to form square or rhombus-shaped grooves so that the core member has a surface roughness to prevent slipping.

또 다른 보호부재 두께조절공정(S300)으로는 압출기를 통과시켜 두께를 형성시키는 방법 등이 있다.Another protective member thickness control process (S300) includes a method of forming a thickness by passing through an extruder.

상기와 같이 보호부재(20)의 두께가 조절되면 냉각공정(S400)을 통해 보호부재를 냉각한 후 권취하여 보관 및 사용한다, 냉각의 방법으로는 냉각장치를 이용하거나 상온에서 냉각시키는 방법 어느 것을 사용하여도 무방하다.When the thickness of the protective member 20 is adjusted as described above, the protective member is cooled through the cooling process (S400), then wound and stored and used. You can also use it.

한편 본 발명인 띠형 섬유보강재의 제조방법에 있어서 첨부도면 도 5에 도시된 바와 같이 상기 코어부재(10)를 형성시 제직된 낱장의 코어부재(20)를 2개층 이상으로 적층시키고 표면에 보호부재(20)를 형성시킬 수 있다.Meanwhile, in the method of manufacturing a strip-shaped fiber reinforcement according to the present invention, as shown in the accompanying drawings, FIG. 5, when forming the core member 10, the core member 20 of a woven sheet is stacked in two or more layers, and a protective member ( 20) can be formed.

또한 첨부도면 도 6에 도시된 바와 같이 상기 코어부재(10)의 형성방법으로 한장을 2개층 이상으로 지그재그 형태로 접은 후 표면에 보호부재(20)를 형성시킬 수 있으며, 상기와 같이 코어부재(10)를 적층 형태로 구조를 변경하면 인장강도를 용이하게 조절할 수 있기 때문이다.In addition, as shown in the accompanying drawings, the core member 10 may be formed by folding one sheet in a zigzag shape in two or more layers, and then forming a protective member 20 on the surface. As described above, the core member ( This is because the tensile strength can be easily adjusted by changing the structure of 10) into a stacked form.

본 발명인 띠형 섬유보강재의 다른 제조방법은 위사와 경사를 교차시켜 코어부재(10)를 제직하는 코어부재 제조공정(S100)을 수행한다.Another manufacturing method of the belt-shaped fiber reinforcement according to the present invention performs the core member manufacturing process (S100) of weaving the core member 10 by crossing the weft yarn and the warp.

이때 상기 코어부재(10)는 PE사, PP사, PET사, LCP사, 탄소섬유, 유리섬유 중 어느 하나를 사용하며 제직의 형태는 평직(Plane), 능직(Twill), 주자직(Satin) 중 어느 하나의 제직 형태를 사용하여 제조한다.At this time, the core member 10 is made of any one of PE yarn, PP yarn, PET yarn, LCP yarn, carbon fiber, and glass fiber, and the form of weaving is plain weave (Plane), twill weave (Twill), satin weave (Satin). It is manufactured using any one of the woven forms.

한편 코어부재(10)의 제직시 길이를 형성하는 쪽의 경사가 폭을 형성하는 위사보다 두께를 두껍게 형성하여 사용할 수도 있으며, 이때 길이 방향에 사용되는 경사의 두께를 두껍게 형성하는 이유는 길이 방향 쪽의 인장력을 더 높게 형성시키기 위함이며 인장력 조절도 용이한 이점이 있기 때문이다.On the other hand, when weaving the core member 10, the warp of the side forming the length may be formed to be thicker than the weft forming the width, and the reason for forming the thickness of the warp used in the longitudinal direction is thicker in the longitudinal direction. This is because it is to form a higher tensile force and has an advantage that it is easy to adjust the tensile force.
