이음부 보강된 토목용 매트 및 그의 제조방법Civil mats with reinforced joints and manufacturing method thereof
본 발명은 이음부가 보강된 토목용 매트 및 그의 제조방법에 관한 것으로서, 더욱 상세하게는 토목용 매트의 이음부의 인장 강도를 원단 강도 수준 혹은 그 이상으로 유지시켜 결합시킴에 따라 토목용 매트의 전체적인 인장 강도 및 내구성을 향상시킨 이음부 보강된 토목용 매트 및 그의 제조방법에 관한 것이다.The present invention relates to a civil engineering mat reinforced with a joint and a method of manufacturing the same. More specifically, the overall tensile strength of the civil engineering mat is maintained by combining the tensile strength of the joint of the civil engineering mat at or above the fabric strength level. The present invention relates to a joint reinforced mat for improved strength and durability, and a method of manufacturing the same.
일반적으로 토목용 매트는 연약지반에 설치되어 강우에 의한 토사의 유실로 인한 산사태나 지반의 함몰 등의 변형을 방지하거나 강우가 폐기물로 유입된 후 폐수로 방출되는 것을 방지하기 위해 사용하는 것이 보편적이다. 상기 연약지반은 주로 부드럽고 압축성이 큰 토층으로 구성되며, 이러한 연약지반 위에 구조물을 건설하기 위해서는 직접 또는 간접적으로 지반을 강화 안정시키기 위한 처리가 선행되어야 한다. In general, civil mats are generally installed on soft ground to prevent deformation of landslides and ground depressions due to the loss of soil due to rainfall, or to prevent rainfall from being discharged into the wastewater after it enters the waste. . The soft ground is mainly composed of soft and highly compressible soil layer, and in order to construct a structure on the soft ground, a process for reinforcing and stabilizing the ground must be preceded directly or indirectly.
현재 연약지반 처리공법에서 토목용 매트 포설공법이 가장 경제적이고 시공이 쉽기 때문에 토목용 매트 포설공법이 일반적으로 사용되고 있다. 토목용 매트 포설 공법은, 도 1에 도시한 바와 같이, 연약지반(2)과 그 위에 설치되는 성토(4)의 사이에 토목용 매트(6)를 포설하는 방법이 많이 행해지고 있다.At present, civil mat laying method is most commonly used in soft ground treatment because it is the most economical and easy construction method. In the civil engineering mat laying method, as shown in FIG. 1, many methods of laying the civil engineering mat 6 are performed between the soft ground 2 and the fill 4 provided on it.
이러한 토목용 매트는 먼저 공장에서 폭 2~5m 정도로 직조한 원단을 공사 현장으로 운반한 후, 현장에서 롤에서 풀려져 나오는 원단의 양쪽 변부를 폭 방향으로 겹쳐 놓고 봉제하여 연결함으로써 광폭의 토목용 매트로 만들어, 이를 연약지반 위에 포설하여 사용한다. 그러나 이렇게 봉제되어 완성되는 토목용 매트의 원단 이음부는 강한 응력이 집중적으로 작용될 경우, 상기 이음부의 인장 강도가 크게 저하되어 원단의 이음부가 찢어져서 보강 역할을 할 수 없게 되는 문제점이 있었다. 이와 같이 이음부가 찢어지면 곧 상부 지반의 국부적인 파괴 및 유동, 융기, 함몰, 침하 등의 현상을 발생시킬 수 있다.This civil mat is a wide range of civil mats by transporting fabrics woven about 2 ~ 5m wide at the factory to the construction site, and then sewing and connecting both sides of the fabric released from the roll in the width direction. It is used to install it on the soft ground. However, when the fabric joint of the civil mat is sewn and finished so that a strong stress is concentrated, there is a problem that the tensile strength of the joint is greatly reduced and the joint of the fabric is torn to play a role of reinforcement. If the joint is torn in this way, local breakdown and flow, uplift, depression and settlement of the upper ground may occur.
이러한 문제를 해결하기 위해 국내 특허 공개 제2008-0099311호는 원단 이음부의 제봉사가 원단 이음부에 상처를 주어 이음부의 간격이 벌어지면서 원단 이음부가 찢어지는 현상을 해하기 위해 이음부 사이에 접착제를 분사하여 일정 두께로 도포하여 원단 이음부의 강도를 향상시키는 기술을 개시하고 있다. In order to solve this problem, Korean Patent Publication No. 2008-0099311 discloses that a seamstress of the fabric joints hurts the fabric joints so that the gap between the joints is widened and the fabric joints are torn.

본 발명에 의하면 토목용 매트의 봉제된 이음부에서의 인강강도와 파단강도가 향상되는 고강도 토목용 매트를 제공함으로써, 이음부의 경계면이 찢겨 지는 것을 사전에 예방할 수 있고, 또한 이음부의 인장강도가 원단강도 수준 혹은 그 이상을 유지하여 연약 지반에 매립되어도 지반침하에 의한 파손 없이 항구적으로 시공 상태를 유지할 수 있어서 연약지반 처리공사의 시공 품질을 향상시킬 수 있다. According to the present invention, by providing a high-strength civil engineering mat which improves the tensile strength and the breaking strength at the sewn joint of the civil engineering mat, it is possible to prevent the boundary surface of the joint from being torn in advance, and also the tensile strength of the joint Even if it is buried in the soft ground by maintaining the strength level or more, it is possible to maintain the construction condition permanently without damage due to ground subsidence, thereby improving the construction quality of the soft ground treatment work.
또한 종래와 같이 이음부가 찢겨질 경우에는 토목용 매트 상부에 적재 성토된 토사 및 쇄석 등을 다시 제거한 후에 토목용 매트를 재시공하여야 하는 불편한 과정을 거침으로써 추가 공사비가 발생되는데, 본 발명에서와 같이 이음부의 인장강도가 개선되면 이와 같은 문제를 미연에 방지하여 추가 공사비의 발생을 막을 수 있고, 종래 사용하던 토목용 매트의 인장강도를 개선시킴에 따라 그 품질이 상위인 토목용 매트를 사용하지 않고, 낮은 그레이드의 기초 원단을 사용하게 하므로 토목용 매트의 원가를 낮출 수 있어, 막대한 비용 절감 효과를 제공할 수 있다.In addition, when the joint is torn as in the prior art, additional construction costs are generated by undergoing an inconvenient process of re-installing the civil engineering mat after removing the soil and crushed stone stacked on top of the civil engineering mat, but as in the present invention. If the negative tensile strength is improved, this problem can be prevented in advance, thus preventing additional construction costs, and improving the tensile strength of the civil engineering mats used in the past, without using civil mats of higher quality, The use of low grade base fabrics can reduce the cost of civil engineering mats, providing significant cost savings.

이하에서 첨부된 도면을 참조하여 본 발명을 상세히 설명하기로 한다. 우선, 도면들 중, 동일한 구성요소들은 가능한 한 동일한 참조부호로 표시한다. 본 발명을 설명함에 있어, 관련된 공지기능 혹은 구성에 대한 구체적인 설명은 본 발명의 요지를 모호하지 않게 하기 위하여 생략한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. First, among the drawings, like elements are denoted by the same reference numerals as much as possible. In describing the present invention, detailed descriptions of related well-known functions or configurations are omitted in order not to obscure the subject matter of the present invention.
종래에는 토목용 매트와 매트 사이의 이음부 강도 저하가 봉제사에 의해 상처난 원단이나 봉제사의 강도에 의한 것이라고 보고 이러한 문제에 초점이 맞추어져 있었다. 그러나 본 발명자들이 일반 토목용 매트를 이용하여 이음부 부분의 인장 강도를 시험해 본 결과, 이음부의 인장강도는 원단이나 봉제사의 강도에 의해서 좌우되는 것이 아니라, 토목용 매트의 변부 말단의 조직에 가장 큰 영향을 받는 것으로 확인하였다. 즉, 좁은 폭의 토목용 매트 원단의 이음부 부분이 분리되는 경우는 열선 커팅(heater cutting)된 원단 말단의 변부가, 양방향으로 주어지는 힘에 의해 가로 방향으로 밀려나오는 경사 방향의 실의 힘을 이기지 못하고 터져 나오는 경우이다. 따라서 토목용 원단 변부 조직을 구조 설계를 통하여 강화해주거나, 변형시키는 것이 토목섬유 원단의 이음부 부분의 봉합 강도를 증가시키는 핵심적인 역할을 할 것이라는 사실에 착안하여 본 발명을 완성하게 되었다. 본 발명자들은 토목용 매트 원단의 변부의 원단을 접거나, 위사 방향의 원사를 경사 조직안으로 말아 넣거나, 변부 조직을 강화하기 위하여 레노 조직을 넣어준 결과, 원단 이음부의 강도가 열선 커팅된 일반적인 토목용 매트에 비해 획기적으로 개선되는 것을 발견하여 본 발명을 완성하기에 이르렀다. Conventionally, this problem was focused on the fact that the decrease in the joint strength between the civil engineering mat and the mat was due to the strength of the fabric or sewing thread wound by the sewing thread. However, when the present inventors tested the tensile strength of the seam using a general civil mat, the tensile strength of the seam is not dependent on the strength of the fabric or sewing thread, but is the largest on the tissue at the edge of the civil mat. It was confirmed to be affected. In other words, when the joint part of the narrow mat of civil engineering mat is separated, the edge of the heat-cutting end of the fabric shall not overcome the force of the thread in the inclined direction pushed out in the horizontal direction by the force given in both directions. It is a case of popping out. Therefore, the present invention has been completed in view of the fact that reinforcing or deforming geotextile edge tissue through structural design will play a key role in increasing the sealing strength of the seam portion of the geotextile fabric. The present inventors folded the fabric of the edge of the civil engineering mat fabric, rolled the yarn in the weft direction into the inclined tissue, or put the leno tissue to reinforce the edge tissue, the general civil engineering for the heat-cut cutting of the strength of the fabric joint It has been found to be a significant improvement over the mat, thus completing the present invention.
도 3은 본 발명의 일 실시예에 따른 토목용 매트의 조직을 설명하기 위한 개략사시도이다. 도 3을 참조하면, 본 발명의 일 실시예의 이음부가 보강된 토목용 매트는 복수의 재단된 원단들 사이에 단부들이 연결되는 이음부가 형성되어 원단의 폭이 넓어지는 토목용 매트로서, 상기 토목용 매트는 순차적으로 서로 평행하게 배열된 경사(20)들과 상기 경사들과 교차되어 있는 (interlaced) 위사들(10)로 구성된 원단부(100)와 변부(200)로 구성되고, 상기 변부(200)는 변부의 위사(10)를 경사(20) 조직 안쪽으로 말아 넣어 경사(20)와 함께 교락하여 제직되는 변부 보강부(30)를 포함하고, 상기 이음부는 포개진 상기 변부 보강부(30)를 포함하는 변부(200)를 봉제하여 연결되는 것을 특징으로 한다. Figure 3 is a schematic perspective view for explaining the organization of the civil engineering mat according to an embodiment of the present invention. Referring to Figure 3, the civil mats reinforced with a joint of an embodiment of the present invention is a civil mat is a mat for the width of the fabric is formed by connecting the end portion is connected between a plurality of cut fabric, the civil engineering The mat is composed of a distal end 100 and an edge part 200 composed of warp yarns 20 arranged in parallel with each other and the weft yarns 10 interlaced with the warp yarns. ) Includes a side reinforcement part 30 which is woven by twisting the weft 10 of the edge part into the inclination 20 tissue and woven together with the inclination 20, wherein the joint part is overlapped with the side reinforcement part 30. It is characterized in that the sewing portion 200 is connected to include.
본 발명에서는 토목용 매트와 매트 사이의 이음부의 봉합 강도를 향상 시키기 위하여 경사 방향의 실 뭉치가 터져 나오지 못하도록 토목용 매트 원단의 변부 조직을 변형시켜 설계하였다. 우선 상기 변부 보강부(30)에 의해서 위사를 토목용 매트 조직 안으로 넣어 주어 경사 방향의 실과 엮어 줌으로써, 좁은 폭의 원단과 원단을 봉제하여 광폭의 원단으로 제조한다. In the present invention, in order to improve the sealing strength of the joint portion between the civil mat and the mat was designed by modifying the edge tissue structure of the civil mat fabric so that the bundle of yarn in the diagonal direction does not burst. First, by inserting the weft yarn into the civil engineering mat tissue by the edge reinforcing portion 30 to weave the yarn in the diagonal direction, sewing a narrow width fabric and fabric to produce a wide fabric.
이렇게 생산된 토목용 매트는 이음부의 봉합 강도가 현저하게 증가된다. 이는 양방향으로 가해지는 힘에 의하여 경사 방향의 실이 변부로 빠져나가게 될 때, 변부 보강부(30)가 경사 방향의 실의 이탈을 막고, 봉제선 안쪽의 실은 양방향으로 뭉치면서 변부 보강된 위사 방향의 실 말단을 더욱 조여 위사가 빠져나가는 현상을 방지하기 때문이다. 따라서 본 발명의 토목용 매트는 일반 토목용 매트에 비해 이음부 부분의 봉합 강도가 현저하게 증가하고 내구성이 크게 향상되어 토목용 매트 전체의 강도가 향상된 연약지반 처리용 토목용 매트를 광폭으로 생산할 수 있도록 한다.Civil mats produced in this way is significantly increased the sealing strength of the joint. This is because when the thread in the inclined direction is released to the edge by the force applied in both directions, the edge reinforcement 30 prevents the separation of the thread in the inclined direction, the yarn inside the seam line unites in both directions in the weft direction of the side reinforced This is because the thread ends are further tightened to prevent the weft from coming out. Therefore, the civil engineering mat of the present invention can produce a wide range of civil ground mats for soft ground treatment with improved strength of the entire civil mats, with a significant increase in the seam strength of the joints and a significant increase in durability compared to general civil mats.

이하에서 실시예를 들어 본 발명에 대하여 더욱 상세하게 설명한다. 다만 이러한 실시예는 본 발명을 제한하는 것이 아니고, 단지 예시를 위한 것이다. Hereinafter, the present invention will be described in more detail with reference to Examples. However, these examples are not intended to limit the present invention, but are for illustration only.

폴리프로필렌 원사로 토목용 매트를 제직하면서 변부를 열선 처리하여 일정 부분 변부에 원사뭉침이 발생하도록 유도하며 원단을 생산하였다. 경위사로는 840 데니어 폴리프로필렌 원사를 사용하였고, 밀도는 인치당 16가닥(16*16/inch)을 넣어 주었다. 봉제 시 두 원단을 약 1~6 cm 정도 겹치게 놓고 3000 데니어 폴리에스터 원사로 4선 봉제하여 토목용 매트를 수득하였다. While weaving civil engineering mats with polypropylene yarns, the edges were heated to induce yarn agglomeration on the edges and produced fabrics. As a weft yarn, 840 denier polypropylene yarns were used, and the density was 16 strands (16 * 16 / inch) per inch. Upon sewing, the two fabrics were overlapped by about 1 to 6 cm, and four lines were sewn with 3000 denier polyester yarn to obtain a civil engineering mat.
수득된 토목용 패트의 인장 강도 측정 결과, 하기 표 1에 나타낸 바와 같이, 기초 원단의 인장 강도는 36.9 kN/m 정도였고, 이음부 부분의 봉합 강도는 18.7 kN/m로 확인되었다. 또한 원단을 육안으로 관찰해 본 결과, 도 6의 사진과 같이, 원단 이음부가 찢어질 때, 열선 처리된 변부의 원사 뭉침이 위사 방향의 힘을 이기지 못하고 터져 나오면서 다량의 경사 방향의 실이 터져 나온 것을 확인하였다.As a result of measuring the tensile strength of the obtained civil engineering pad, as shown in Table 1 below, the tensile strength of the base fabric was about 36.9 kN / m, and the sealing strength of the joint part was found to be 18.7 kN / m. In addition, when the fabric is visually observed, as shown in the photograph of FIG. 6, when the fabric joint is torn, a large amount of yarn in the inclined direction is popped out as the bundle of yarns of the heated wired edges do not overcome the force in the weft direction. It was confirmed.

폴리프로필렌 토목용 매트 원단의 변부를 보강하기 위하여 두 원단의 변부를 접은 후, 원단이 겹쳐진 부분을 3000데니어 폴리에스터 원사로 4선 봉제하였다. 이후 네 겹으로 접혀진 두 원단의 이음부 부분의 봉합 강도를 측정하여 그 결과를 하기 표 2에 나타내었다. 측정 결과 두 겹으로 겹쳐진 원단의 봉합 강도는 18.7 kN/m로 측정되었다. 이러한 결과는 이음부 부분의 봉합 강도가 다소 향상된 것을 보여주었으나, 봉합 강도 향상 효과가 부족하고, 봉제되는 부분이 두꺼워지고 고속으로 봉제할 때 접혀 있는 부분의 폭이 일정하게 유지 되지 않아 봉제가 어려운 문제가 있었다. In order to reinforce the edges of the polypropylene civil engineering mat fabric, the edges of the two fabrics were folded, and the overlapped portions of the fabrics were sewn into four lines with 3000 denier polyester yarns. Then, the sealing strength of the joint portions of the two fabrics folded in four layers was measured and the results are shown in Table 2 below. As a result of the measurement, the sealing strength of the two-ply fabric was 18.7 kN / m. These results showed that the seam strength of the seam was slightly improved, but the seam strength was insufficient, and the sewing area became thick and the width of the folded portion was not kept constant when sewing at high speed. There was a problem.

토목용 매트의 원단 제직 시 원단 변부 보강 장치를 설치하여 양쪽 변부의 위사를 안쪽으로 말아주고, 경사 방향의 실과 엮어주어 변부 보강부를 형성하여 토목용 매트를 제조하였다. 이때 변부 보강 장치를 이용하여 양쪽 변부의 위사를 제직 시 1 cm 이상 원단 안쪽으로 말아 넣고 제직하였다. 제조된 토목용 매트의 이음부 인장강도를 측정하여 하기 표 3에 나타내었다. 이어서 좁은 폭의 토목용 매트 원단 봉제 시 토목 섬유 원단 양쪽 변부를 3000 데니어 폴리에스터 원사로 4선 봉제하여 봉합 강도를 측정하였다. 변부 보강부를 형성한 원단의 위사 방향 봉합 강도를 측정해 본 결과 32.8 kN/m 수준으로 측정되었는데, 이는 기존의 열선 커팅 방식으로 생산된 이음부의 봉합 강도(18.71 kN/m)대비 75.5% 향상된 수치이다. 위사를 경사 조직에 말아 넣어 제직한 원단의 봉합 강도가 기존의 열선 커팅된 원단의 봉합 강도보다 월등히 향상된 이유는 변부의 위사가 원단 안쪽으로 말려 들어가면서 변부가 사라지는 효과가 발생하였고, 양방향으로 당기는 봉합 강도 테스트시 4선 봉제선 안쪽의 경사가 4선 봉제 라인 안쪽으로 양방향으로 몰리면서, 안쪽으로 말려 들어오는 위사를 강하게 잡아주었기 때문으로 추정된다. 결과적으로 변부 보강된 원단의 이음부 부분을 양방향으로 잡아당긴 경우, 위사 방향의 원사가 빠지지 못하고대부분 끊어지면서 터져 나오는 것이 이를 입증해준다. 결과적으로 변부 보강 처리된 원단 이음부의 봉합 강도(32.8 kN/m)는 기초 원단 인장 강도 36.9 kN/m 대비 88.9% 수준으로 확인되었다. When weaving the fabric for civil engineering mats, fabric side reinforcement devices were installed to roll the wefts of both sides inwards, and weaved with threads in the inclined direction to form edge reinforcement parts to manufacture civil mats. At this time, weaving the weft of both sides by using the edge reinforcement device rolled into the fabric more than 1 cm in the weaving. The tensile strength of the joint of the manufactured civil mat is measured and shown in Table 3 below. Subsequently, when sewing a narrow width of the civil mat mat fabric, four sides of both sides of the geotextile fabric were sewn with 3000 denier polyester yarn to measure the sewing strength. As a result of measuring the weft direction sealing strength of the fabric forming the edge reinforcement, it was measured to be 32.8 kN / m, which is 75.5% higher than the sealing strength of the joint produced by the hot wire cutting method (18.71 kN / m). . The reason why the sealing strength of the fabric woven by weaving the yarn into the inclined tissue is significantly improved than the sealing strength of the conventional hot-cut fabric. The reason is that the weft of the edge is rolled into the fabric and the edge disappears. It is presumed that the inclination of the four-line seam was pushed inward in the two-wire seam line, so that the warp yarns that were curled inward strongly held. As a result, when the joint part of the edge-reinforced fabric is pulled in both directions, it is proved that the yarn in the weft direction does not fall out and is mostly broken off. As a result, the sealing strength (32.8 kN / m) of the edge portion reinforced fabric joint was found to be 88.9% of the base fabric tensile strength of 36.9 kN / m.

양쪽 변부의 위사를 조직 안으로 밀어 넣은 실시예 1의 변부 보강 원단의 이음부 강도를 더욱 강화시키기 위하여, 변부에 원사가 빠져나오는 것을 방지하기 위하여 변부에 레노 조직을 6가닥을 엮어 넣어 보강해 주었다. 레노사로는 300 DTY (draw textured yarn) 원사를 사용하였다. 변부 보강 처리된 실시예 1의 토목용 매트 (32.8 kN/m) 대비 레노 조직을 추가로 넣어준 토목용 매트(34.5 kN/m)의 경우 봉합 강도가 약 5% 정도 더 향상되었다. 이는 열선 커팅된 일반 토목용 매트의 이음부 봉합 강도 대비 84% 향상된 수준이며, 기초 원단의 인장 강도(36.9 kN/m) 대비 93.5% 수준을 나타낸 것이다. 이는 레노 조직으로 변부 보강부를 형성한 원단의 위사 방향의 원사 이탈을 다시 한번 막아줌으로써 단순히 위사 방향의 원사가 끊어지지 않고 터져 나오는 경우를 방지했다고 볼 수 있다. In order to further strengthen the joint strength of the edge reinforcing fabric of Example 1 in which the wefts of both edges were pushed into the tissues, 6 strands of leno tissue were woven and reinforced to prevent the yarns from escaping the edges. As Lennosa, 300 DTY (draw textured yarn) yarn was used. For the civil mats (34.5 kN / m) with additional leno tissue compared to the civil mats (32.8 kN / m) of the edge reinforcement treated Example 1, the sealing strength was further improved by about 5%. This is an improvement of 84% compared to the joint seam strength of the heat-cut general civil mat, and 93.5% to the tensile strength (36.9 kN / m) of the base fabric. This can be seen to prevent the case that the yarn in the weft direction simply breaks out by simply preventing the yarn out of the weft direction of the fabric formed the edge reinforcement portion of the leno structure.
