Abstract
Description
본 발명은 터널을 굴착 형성함에 있어서 터널에 방수성능을 부여하기 위하여 이용되는 터널방수공용 방수시트에 관한 것이다.The present invention relates to a waterproof sheet for tunnel waterproofing used to provide waterproof performance to the tunnel in the excavation of the tunnel.
배수성능에 따른 터널의 종류로는 크게 배수터널과 방수터널로 분류되고 대부분의 경우 수압을 받지 않는 배수터널이 널리 시행되고 있다. 여기서 배수터널과 방수터널은 dd터널의 전단면에 방수공을 하는 것에 있어서는 동일한 같으나 배수터널의 경우는 일정한 장소로 집수하여 배수하는 구조가 방수터널과 다를 뿐이다.Tunnels according to drainage performance are classified into drainage tunnels and waterproof tunnels. In most cases, drainage tunnels that do not receive hydraulic pressure are widely used. Here, the drainage tunnel and the waterproof tunnel are the same in the case of making a waterproof hole in the front end surface of the dd tunnel, but in the case of the drainage tunnel, the structure of collecting and draining to a certain place is different from the waterproof tunnel.
터널을 굴착 형성하는 터널공은 도 6 및 도 7에 도시된 바와 같이 먼저 완성 터널보다 약간 큰 반원형 단면형상으로 기초터널(100)을 굴착 형성한 후 기초터널(100)의 내면에 숏크리트를 타설하고 숏크리트층(101)의 내면에 방수공을 시행하며 방수층(102)의 내면에 라이닝콘크리트(103)를 타설함으로서 완성된다.Tunnel hole excavation to form the tunnel, as shown in Figs. 6 and 7 first excavated and formed the foundation tunnel 100 in a semi-circular cross-sectional shape slightly larger than the completed tunnel, and then shotcrete on the inner surface of the foundation tunnel 100 Waterproofing is applied to the inner surface of the shotcrete layer 101 and completed by pouring lining concrete 103 on the inner surface of the waterproofing layer 102.
한편 상기와 같이 터널공을 함에 있어서 터널에 방수성능을 부여하기 위한 종래의 방수공법은 기초터널의 내면에 타설된 숏크리트 내면에 폴리에스터나 폴리프로필렌으로 직조되고 일정한 두께와 투수성을 갖는 부직포를 부착한 후 부직포 표면에 EVA, ECB, PVC 필름으로 되고 소요의 강도와 수밀성이 우수한 방수시트를 부착하는 방법으로 시행하고 있다. 그리고 여기서 방수시트는 열융착에 의한 방법으로 연속하여 연결하고 있으며 이와 같이 방수공을 함으로서 지하수가 라이닝콘크리트에 스며드는 것을 방지하여 누수방지는 물론 터널의 수명을 연장하도록 하고 있다.On the other hand, the conventional waterproofing method for imparting waterproofing performance to the tunnel in the tunnel hole as described above is attached to the inner surface of the shot tunnel woven with polyester or polypropylene on the inner surface of the shot tunnel, and attaches a nonwoven fabric having a constant thickness and permeability. After that, EVA, ECB, PVC film on the surface of the non-woven fabric is carried out by attaching a waterproof sheet having excellent strength and watertightness. And here, the waterproof sheet is continuously connected by the method of heat fusion, and by waterproofing in this way, groundwater is prevented from penetrating the lining concrete to prevent leakage and extend the life of the tunnel.
그런데 상기와 같은 종래의 방수공은 터널의 천정부에서 행하는 것이므로 근본적으로 많은 인력과 시간이 소요되는 것이기는 하나 숏크리트의 내면에 부직포를 부착하고 그 내측 표면에 방수시트를 부착하는 2단계를 거쳐 완성하는 것이므로 그 시공이 더욱더 불편한 것이다. 또 숏크리트에서 발생되는 수산화칼슘으로 인하여 부직포의 집수기능이 약화되어 누수의 원인이 되기도 하는 것이다.However, the above-mentioned conventional waterproof ball is performed in the ceiling of the tunnel, but it takes a lot of manpower and time, but it is completed through two steps of attaching a nonwoven fabric to the inner surface of the shotcrete and attaching a waterproof sheet to the inner surface thereof. It is because the construction is more inconvenient. In addition, the calcium hydroxide generated from shotcrete weakens the collecting function of the nonwoven fabric and causes leakage.
본 발명은 상기와 같은 종래의 문제점을 고려하여 발명된 것으로서, 그 목적으로 하는 것은, 방수공을 위한 부직포와 방수시트본체를 일체화함으로서 방수공을 용이하게 할 수 있고 또 부직포에 유공배수관을 구비시킴으로서 배수성을 크게 향상시킬 수 있는 터널방수공용 방수시트를 제공하고자 하는 것에 있다.The present invention has been invented in view of the above-mentioned conventional problems, and its object is to integrate a nonwoven fabric and a waterproof sheet body for waterproofing holes to facilitate the waterproofing hole, and to provide a non-woven fabric with a hole drainage pipe. It is an object of the present invention to provide a waterproof sheet for tunnel waterproofing which can greatly improve drainage.
