차수용(遵水用)매드Car Watering Mad

제1도의 (a)(b)도는 종래의 차수용 매트를 예시한 일부 절개사시도.(A) (b) of FIG. 1 is a partial cutaway perspective view illustrating a conventional order mat.

제2도의(a)도는 본 고안의 일부 절개사시도이며, (b)도는 본 고안의 일부 확대 단면도.(A) of FIG. 2 is a partially cutaway perspective view of the present invention, and (b) is a partially enlarged cross-sectional view of the present invention.

본 고안은 터널, 방파제, 용수로, 배수토등의 축조물에 있어서, 발생하는 누수협상을 방지하기 위해 사용되는 차수용(遮水用)메트에 관한 것이다.The present invention relates to a water-use mat used to prevent leakage negotiations that occur in constructions such as tunnels, breakwaters, waterways, drainage soils, and the like.

본 고안은 비교적 응점이 낮은 합성섬유직포를 가열용융하여 일체화된 차수막에다 그 융점이 높은 합성섬유부직포를 심어서 되는 것을 특징으로 하는 것이다. 예를들어 P.E직포의 상면에 P.P 부직포를 겹쳐놓고 니들펀칭을 한 P.E 직포면을 그 용융온도로 가열로울러등에 의하여 가열 용융시킴으로서 상기 부직포의 섬유올이 그 P.E 직포의 용융면에 심어져 일체화된 차수막을 형성한 차수용 메트를 제공함으로서 종래의 문제점을 시정하려는데 그 목적이 있는 것이다.The present invention is characterized in that a synthetic fiber nonwoven fabric having a high melting point is planted in an integrated film obtained by heating and melting a synthetic fiber fabric having a relatively low dew point. For example, by stacking a PP nonwoven fabric on top surface of PE woven fabric and heat-melting the needle woven PE woven surface by heating roller at the melting temperature, fiberol of the nonwoven fabric is planted on the molten surface of the PE woven fabric and integrated The purpose is to correct the conventional problems by providing a mat for the order formed.

종래에도 상기의 경우와 같은 축조물의 누수협상으로 토사의 누출 및 세금이 생겨서 그 축조물이 침하되어 파손 또는 붕괴되는 위험을 방지하기 위하여 사용하여 왔다. 이 종래의 차수용 매트는 제1도의 (a)에서와 같이 합성섬유부직포(2)의 일측면에다가 합성수지제 필름(1a)을 접착제(3)로 접착시키거나 또는 (b)도에서와 같이 합성섬유부직포(2)를 합성섬유직포(1)에다 니들펀칭한 직포면에 다시 합성수지제필름(1a)을 접착제(3)로 접착시킨 것이었다. 그러나 차수막 역할을 하는 합성수지제 필름(1a)은 성형시킬때 그 수지의 분자배열 방향이 압출연신되는 방향으로 배열되는 것이어서, 필름이 압출연신되는 길이방향(종방향)의 인장강도는 그 방향(흉방향)보다 월등이 강한 것이다. 그런데 차수막은 사방으로 그 인장강도가 균일하여야 하는 것이어서, 전자는 그 횡방향의 인장강도를 보충하는데 따록는 두끼에 해당하는 재료의 낭비를 가져오며, 후자의 직포는 차수성이 전혀 없어서 차수막으로서 필름(1a)을 다시 접착제(3)로 접착하여야 하는 낭비를 감수하여야 함으로 위의 양자는 그 제조원자 및 가공비용이 가증되는 것이다.Conventionally, it has been used to prevent the risk of sediment leakage and tax caused by sedimentation and leakage of sediment due to water leakage negotiations of such constructions. This conventional order mat is bonded to one side of the synthetic fiber nonwoven fabric 2, as shown in (a) of FIG. 1, and the synthetic resin film (1a) is bonded with an adhesive (3) or synthesized as shown in (b). The fiber nonwoven fabric 2 was bonded to the synthetic fiber woven fabric 1 by needle punching the synthetic resin film 1a with the adhesive 3 again. However, the synthetic resin film 1a serving as the membrane is arranged in the direction in which the molecular arrangement direction of the resin is extruded and stretched, so that the tensile strength in the longitudinal direction (longitudinal direction) in which the film is extruded and stretched is determined in that direction. Direction is stronger than). By the way, the film should be uniform in tensile strength in all directions, so that the former makes up for the lateral tensile strength, which leads to the waste of materials corresponding to two meals. Both of the above would increase the manufacturing cost and processing cost of the above, because the waste of having to attach (1a) to the adhesive 3 again.

본 고안은 상기한 바와 같은 문제점을 해결하기 위하여 제안되는 것으로서, 그 내용을 제2도의 예시 도면에 의해 상세히 설명하면 다음과 같다. 예를들어 1,200D 정도의 P.E 후렐트얀(이하 P.E 직포라함)(1)의 상면에 P.P 섬유올(2a)로 되는 일정한 두께의 일발적인 부직포(2)를 겹쳐놓고 니들펀칭한 것에 있어서, 상기 P.E 직포(1)를 가열용융하여 일체화시킨 차주막(1a')에 P.P 섬유올(2a)이 감착되게 한 것을 특징으로하는 차수용 메트인 것이다.The present invention is proposed to solve the problems as described above, the contents of which will be described in detail by way of example in Figure 2 as follows. For example, needle punching is made by overlapping a primary nonwoven fabric 2 of a constant thickness of PP fiberol 2a on the upper surface of a PE floppy yarn (hereinafter referred to as a PE woven fabric) 1 of about 1,200D. It is an order mat, characterized in that the PP fiberol (2a) is adhered to the primary film (1a ') in which the woven fabric (1) is melted by heat melting.

본 고안의 구성상태를 구체적으로 설명하면 다음과 같다. 즉 P.P 부직포는 그 가열용융온도가 180℃-200℃ 정도이고, P.E 직포는 그 가연용융온도가 140℃-160℃정도이므로, P.E 직포(1)를 그 용융온도로서 가열용융하면 그 P.E 직포(1)는 용융되어서 일체화된 상태는 필름과 같이 통기공이 없는 차수막(1a')으로 되는 동시에 P.P 부직포(2)의 섬유올(2a)은 그 차수막(1a')의 일측면에 심어진 상태로 감축되는 것이다.Referring to the configuration of the present invention in detail as follows. In other words, the PP nonwoven fabric has a heat melting temperature of about 180 ° C. to 200 ° C., and the PE woven fabric has a flammable melting temperature of about 140 ° C. to 160 ° C., so that the PE woven fabric 1 is melted at the melting temperature thereof. 1) is melted and integrated into a non-permeable liner film 1a 'such as a film, while the fiberol 2a of the PP nonwoven fabric 2 is reduced in a state planted on one side of the liner film 1a'. Will be.

이때의 P.E 직포(1)의 용융상태는 위사 및 경사의 직목(纖目)에 생긴 통기공이 없어질 정도로 일체화되는 것이며, 그 위사 및 경사는 직교되게 직조된 상태에서 용융되어 일체화된 씨이트가 되는 것이어서, 그 씨이트의 수지의 분자배열방향은 직교되게 형성되는 것이다. 따라서 본 고안에서의 차수막(1a')의 인장강도는 좌우전후가 동일하게 되며, 횡방향의 인장강도는 크게 증대되는 것이다. 그 이유는 섬유가 압출될때 수지의 분자배열 방향이 그 압출방향(종방향)으로 놓여져 형성되는 것이므로 섬유의 길이방향의 인장강도나 파열강도는 그 횡방향보다 월등하게 큰 것이어서 직포의 위사와 경사는 다같이 인장강도가 강한 것이다. 이와같은 위사와 경사가 직교되어 용융된 상태로 일체화된 차수막(1a')이 형성되기 때문인 것이다.At this time, the molten state of the PE woven fabric (1) is integrated to the extent that there are no vent holes formed in the weft and the warp of the warp, the weft and the warp are melted and integrated in the orthogonal weave state sheet Thus, the molecular arrangement direction of the resin of the sheet is formed to be orthogonal. Therefore, the tensile strength of the order film 1a 'in the present invention is the same in the left and right, and the tensile strength in the transverse direction is greatly increased. The reason is that when the fiber is extruded, the direction of the molecular arrangement of the resin is formed in the extrusion direction (longitudinal direction), so that the tensile strength and the tear strength in the longitudinal direction of the fiber are much larger than the transverse direction, so that the weft and warp of the woven fabric Together, the tensile strength is strong. This is because the weft yarn and the warp are orthogonal to each other to form an integrated order film 1a 'in a molten state.

본 고안은 P.E 직포의 통기공을 없이하는 가열용착과정에서 니들펀칭된 P.P 부직포의 섬유를 감착시킨것이므로 종래에 필름과 같은 것에 부직포를 접착시키거나 부직포를 직포에 접착 또는 니들펀칭한 타측의 직포면에다 필름을 다시 접착제(3)로 접착시켜 되는 종래의 모든 문제점을 시정할 수 있는 실용적이고 새로운 차수용 매트를 비교적 싼값으로 제공할 수 있는 효과를 가지는 것이다.The present invention is because the fabric of the needle punched PP nonwoven fabric in the heat welding process without the ventilation hole of the PE woven fabric, the conventional nonwoven fabric on the other side, such as a non-woven fabric or a non-woven fabric bonded or needle punched to the woven fabric In addition, it is possible to provide a practical new novel mat for correcting all the conventional problems of adhering the film to the adhesive 3 again at a relatively low price.
