토목용 복합매트 및 그 복합매트의 제조방법{Civil engineering for composite mat and method of manufacturing the composite mat}Technical Field [0001] The present invention relates to a composite mat for civil engineering and a method for manufacturing the composite mat,

본 발명은 토목용 복합매트 및 그 복합매트의 제조방법에 관한 것으로서 보다 상세하게는 직포와 부직포의 물리적 결합시 조직이 파괴되어 강도가 저하되는 것을 방지하도록 한 토목용 복합매트 및 그 복합매트의 제조방법에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite mat for civil engineering and a method of manufacturing the composite mat, and more particularly, to a composite mat for civil engineering that prevents breakage of a structure during physical bonding of a woven fabric and a non- ≪ / RTI >

현재 하천 및 해양의 토목공사시 보강 및 배수용으로 사용되는 고강도 복합매트는 제방 및 현장의 토사유실을 방지하여 제방과 호안이 붕괴되는 것을 방지하는데 없어서는 안되는 자재로 인식되어져 왔다.The high strength composite mats used for reinforcement and drainage in the civil engineering works of rivers and marine have been recognized as an indispensable material for preventing the collapse of the embankment and the shore by preventing the loss of soil from the embankment and the site.

하지만 보강용 직포매트와 완충용 부직포의 결합에 니들펀칭하여 결합하는 종래의 결합방식은 니들펀칭시 직포매트가 물리적으로 파손되면서 부직포와 결합됨으로 상기 직포매트의 강도를 10~30% 정도 저하시키기 때문에 현장에 투입되어지는 제품의 불량률이 높아져 부실공사를 유발시키는 문제점이 있다.However, in the conventional bonding method in which the bonding of the reinforcing woven mat and the buffering nonwoven fabric is performed by needle punching, the strength of the woven mat is lowered by about 10 to 30% by being bonded to the nonwoven fabric while physically breaking the woven mat at the time of needle punching There is a problem that the defective rate of the product to be put on the site is increased, causing a bad work.

한편 다른 문제점으로 보강용 직포매트와 완충용 부직포를 접착용 시트를 사용하여 결합하였으나 접착용 시트를 이용한 접착 방법 및 구조에 있어서 보강용 직포매트와 완충용 부직포의 양측에 각각 열착용 히팅로울러가 설치되어 있어 보강용 직포매트와 완충용 부직포를 가열 압착함으로써 부직포가 고온의 열에 의해 변형이 발생되며 그로 인해 배수성능인 투수성이 현저히 떨어지는 문제점이 있으며, 또한 보강용 직포매트와 완충용 부직포 사이에 설치되는 접착용 시트가 차수 효과를 발현하여 투수성이 없어 토사유실을 가져와 제방과 호안이 붕괴 되므로 배수용으로 사용할 수 없다.
Another problem is that the reinforcing woven mat and the buffering nonwoven fabric are bonded by using the bonding sheet, but in the bonding method and structure using the bonding sheet, heat-wearing heating rollers are installed on both sides of the reinforcing woven mat and the buffering non- The reinforcing woven mat and the buffering nonwoven fabric are thermally pressed to deform the nonwoven fabric due to the heat at a high temperature. As a result, there is a problem that the water permeability, which is a drainage performance, The adhesive sheet exhibits a water-repellent effect and is not permeable to water, which leads to the loss of the soil, and the embankment and the shore are collapsed.

이러한 종래 문제점을 감안하여 안출한 것으로서 본 발명의 목적은 보강용 직포매트와 완충용 부직포를 접착 결합하여도 직포의 손상 및 변형이 발생하지 않아 강도 저하를 억제시켜 제품의 신뢰도를 향상시키며, 또한 보강용 직포매트와 완충용 부직포의 결합이 간단하고 보강용 직포매트와 완충용 부직포를 결합시키기 위하여 일측은 가열압착하여 접합시키고 일측은 부직포의 변형이 일어나지 않도록 냉각압착하여 제품의 신뢰성이 향상되는 토목용 복합매트 및 그 복합매트의 제조방법에 관한 것이다.
