Description
본 고안은 방수시트에 관한 것으로서, 보다 상세하게는 방수효과가 우수할 뿐만 아니라 시공이 용이하여 공기를 단축할 수 있는 새로운 구조의 방수시트에 관한 것이다.The present invention relates to a waterproof sheet, and more particularly to a waterproof sheet of a new structure that can shorten the air by excellent construction and easy construction.
일반적으로 터널공사와 같은 토목 공사장에서는 도 1에 도시된 바와 같이, 터널의 숏크리트(1) 타설면에 부직포(2)와 방수막(3)을 적층시켜 터널내부로 유입된 물이 터널과 나란하게 설치된 배수관(5)으로 유도되도록 배수공사를 한다. 그러나 이와 같이 시공하는 경우에는 먼저, 터널 굴착면에 숏크리트(1)를 타설하고, 숏크리트(1) 타설면에 부직포(2)를 고정시킨다. 상기 부직포(2)는 그 섬유결을 따라 물을 유도하는 성질이 있는데, 이러한 부직포(2)에 의해 터널 내부로 유입된 물이 배수관(5)으로 유도된다. 이때 부직포(2)는 연결단부가 들뜨지 않도록 흔히 '란델'이라 불리우는 고정부재(6)를 고정못(7)으로 박아 부직포(2)의 연결부위를 고정시킨다. 그리고 차수효과를 얻기 위해 부직포(2) 외측에 방수막(3)을 덧대는데, 이 방수막(3)은 상기 부직포(2)를 고정시킨 고정부재(6)에 열접합시켜 고정한다. 그런 다음 방수막(3) 외측에 콘크리트(4)를 타설하여 터널을 완성한다.In general, civil engineering works such as tunnel construction, as shown in Figure 1, by stacking the non-woven fabric (2) and the waterproof membrane (3) on the shotcrete (1) pour surface of the tunnel side-by-side water flowing into the tunnel Drainage work is to be led to the installed drain pipe (5). However, when constructing in this way, first, the shotcrete 1 is poured into the tunnel excavation surface, and the nonwoven fabric 2 is fixed to the shotcrete 1 casting surface. The nonwoven fabric 2 has a property of inducing water along the fiber, and the water introduced into the tunnel by the nonwoven fabric 2 is led to the drain pipe 5. At this time, the nonwoven fabric 2 drives the fixing member 6, which is often called 'landel', with the fixing nail 7 so as to prevent the connecting end from being lifted to fix the connecting portion of the nonwoven fabric 2. And in order to obtain the order effect, the waterproof membrane 3 is padded on the outside of the nonwoven fabric 2, which is thermally bonded to the fixing member 6 on which the nonwoven fabric 2 is fixed. Then, the concrete (4) is poured outside the waterproof membrane (3) to complete the tunnel.
그러나 이와 같은 방수시공하는 경우에는 상기 종래의 방수시트가 상당히 얇은 형태이므로 방수시공 후, 후속 작업과정에서 방수시트가 파손되는 경우가 흔히 발생된다. 따라서 방수시트가 파손된 부분에 틈새가 생기고, 이 틈새로 누수가 발생하여 방수가 효과적으로 이루어지지 못할 뿐만 아니라 그 시공이 복잡하여 비효율적이였다.However, in the case of such waterproof construction, since the conventional waterproof sheet is considerably thin, after the waterproof construction, the waterproof sheet is often broken in subsequent work. Therefore, a gap is formed in the part where the waterproof sheet is damaged, and water leakage occurs due to the gap, and thus the waterproof is not effectively achieved, and its construction is complicated and inefficient.
한편, 일반적으로 벤토나이트는 팽창성 점토광물로서 물과 접촉되면 수화되면서 물분자를 배척할 때까지 팽윤하는 성질이 있는데, 이에 따라 물분자를 배척하는 방수효과를 얻게 된다. 특히 나트륨계통의 벤토나이트는 투수성이 상당히 우수하며, 팽창성이 13~16배에 이르는 독특한 특성을 가지고 있어서, 항구적인 구조물의 방수재료로 사용되고 있다. 따라서 전술한 바와 같은 문제점에 대해 상기 부직포(3) 대신에 부직포에 벤토나이트가 적층되어 이루어진 방수시트를 숏크리트 타설면에 부착한 다음 방수막을 부착하기도 한다. 그러나 이 경우에는 방수막의 연결부위로 누수가 발생되는 것이 벤토나이트에 의해 커버되기는 하나 이 또한 방수시트를 부착한 다음 다시 방수막을 부착하여야 하므로 작업공정이 복잡하였다.On the other hand, in general, bentonite is an expandable clay mineral, and when swelled in contact with water, the bentonite swells until it rejects water molecules, thereby obtaining a waterproof effect to reject water molecules. In particular, sodium-based bentonite has excellent water permeability, and has a unique characteristic of 13 to 16 times of expandability, and is used as a waterproof material for permanent structures. Therefore, for the above problems, instead of the nonwoven fabric 3, a waterproof sheet formed by stacking bentonite on the nonwoven fabric is attached to the shotcrete surface, and then a waterproof film is attached. However, in this case, the leakage of water into the connection part of the waterproof membrane is covered by bentonite, but it is also complicated because the waterproof membrane must be attached after attaching the waterproof sheet.
본 고안은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 본 고안의 목적은 방수효과가 우수할 뿐만 아니라 각각의 방수재료들이 다층으로 적층되어 제공되므로 시공작업이 용이하여 공기를 단축시킬 수 있어서 실용성이 우수한 새로운 구조의 방수시트를 제공하고자 하는 것이다.The present invention is to solve the problems as described above, the purpose of the present invention is not only excellent in the waterproof effect, but also provided by each of the waterproof materials are laminated in a multi-layer construction to facilitate the construction work to shorten the air It is to provide an excellent new structure waterproof sheet.

본 고안에 따르면, 부직포(10)의 일측에 벤토나이트(20)가 적층되고, 이 벤토나이트(20)의 일측에 직포(30)가 부착되어 이루어진 방수시트에 있어서, 상기 직포(30)의 외측면에는 방수막(40)이 적층되며, 상기 방수막(40)의 적어도 일측 단부는 상기 부직포(10), 벤토나이트(20), 직포(30)의 단부보다 소정량 연장돌출되어 돌출연결부(42)가 구비되어, 구조물의 방수시공시 다수개의 방수시트(50)를 연결부착할 때 상기 돌출연결부(42)가 인접배치되는 방수시트(50)의 상면에 열융착되도록 된 것을 특징으로 하는 방수시트가 제공된다.According to the present invention, the bentonite 20 is laminated on one side of the nonwoven fabric 10, and in the waterproof sheet formed by attaching the woven fabric 30 to one side of the bentonite 20, the outer surface of the woven fabric 30 The waterproof membrane 40 is stacked, and at least one end of the waterproof membrane 40 protrudes a predetermined amount from the ends of the nonwoven fabric 10, the bentonite 20, and the woven fabric 30 so that the protruding connection portion 42 is provided. Thus, when the waterproof construction of the structure when the connection of the plurality of waterproof sheet 50 is provided with a waterproof sheet characterized in that the protruding connection portion 42 is heat-sealed to the upper surface of the waterproof sheet 50 to be adjacently disposed. .
이하, 본 고안의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다. 도 2와 도 3은 본 고안의 바람직한 실시예를 보인 사시도와 사용상태 단면도이다.Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows. 2 and 3 are a perspective view and a cross-sectional view showing a preferred embodiment of the present invention.
본 고안에 의한 방수시트는 부직포(10), 벤토나이트(20), 직포(30), 방수막(40)이 순차적으로 적층되어 이루어진 것으로, 먼저, 부직포(10)의 상면에 벤토나이트(20)를 소정두께로 적층한다. 상기 벤토나이트(20)는 분말상이므로 합성수지와 같은 적절한 바인더를 사용하여 부직포(10)의 상면에 적층한다. 그런 다음 벤토나이트(20)의 상면에 직물(30)을 적층한다. 상기 벤토나이트(20)는 물에 젖을 경우 고정력이 상실되어 부직포에서 이탈될 수 있는데, 이탈된 벤토나이트(20)는 본래의 방수능을 상실하게 된다. 따라서 이와 같이 벤토나이트(20)의 상면에 직포(30)를 적층함으로써 벤토나이트(20)가 이탈되지 않도록 한다. 또한, 이때 사용되는 부직포(10)와 직포(30)는 물을 유도하는 성질을 가지므로 누수된 물을 배수관(5)으로 유도시킨다. 상기 직물(30)로는 얇은 면직물을 사용한다.In the waterproof sheet according to the present invention, the nonwoven fabric 10, the bentonite 20, the woven fabric 30, and the waterproof membrane 40 are sequentially stacked. First, the bentonite 20 is predetermined on the upper surface of the nonwoven fabric 10. Laminate to thickness. Since the bentonite 20 is powdery, it is laminated on the upper surface of the nonwoven fabric 10 using a suitable binder such as synthetic resin. Then, the fabric 30 is laminated on the top surface of the bentonite 20. When the bentonite 20 is wetted with water, the fixing force may be lost, and the bentonite 20 may be separated from the nonwoven fabric. The bentonite 20 may lose its original waterproof ability. Accordingly, by stacking the woven fabric 30 on the upper surface of the bentonite 20, the bentonite 20 is not separated. In addition, since the nonwoven fabric 10 and the woven fabric 30 used in this case have a property of inducing water, the leaked water is guided to the drain pipe 5. As the fabric 30, a thin cotton fabric is used.
그리고 상기 직포(30)의 외측면에 방수막(40)을 적층시킨다. 상기 방수막(40)은 합성수지로 된 것으로, 누수된 물이 터널 내부로 유입되는 것을 차수한다. 이때 상기 방수막(40)의 가로세로 두 측단을 상기 부직포(10)나 벤토나이트(20), 직포(30)의 단부에 비해 소정길이 연장돌출시켜 돌출연결부(42)를 형성한다. 그리고 방수시공시 이 돌출연결부(42)가 인접배치되는 방수시트(50)의 상면에 겹쳐지도록 배치하여 돌출연결부(42)를 열접합시킨다. 이와 같이 하면, 방수시트(50)의 연결부위가 돌출연결부(42)에 의해 커버되므로 연결부위에서 누수가 발생될 염려가 없다.And the waterproof film 40 is laminated on the outer surface of the woven fabric (30). The waterproof membrane 40 is made of synthetic resin, and the leaked water is introduced into the tunnel. At this time, the two side ends of the waterproof membrane 40 are protruded by a predetermined length relative to the ends of the nonwoven fabric 10, the bentonite 20, and the woven fabric 30 to form the protruding connection portion 42. And when the waterproof construction is disposed so that the projecting connection portion 42 overlaps the upper surface of the waterproof sheet 50 to be adjacently disposed to heat-bond the projecting connection portion 42. In this way, since the connecting portion of the waterproof sheet 50 is covered by the protruding connecting portion 42, there is no fear of leakage at the connecting portion.
이상과 같은 본 고안을 이용해 방수시공시에는, 터널 굴착면에 타설된 숏크리트면(1)에 본 고안에 의한 방수시트(50)를 고정못(7)으로 고정시킨다. 이때에는 인접배치되는 방수시트(50)의 부직포(10), 벤토나이트(20), 직포(30)의 단부는 서로 접하고, 상기 연결단부는 인접배치되는 방수시트의 상면으로 위치되도록한다. 그런 다음, 방수시트(50)의 연결단부(42)를 인접배치되는 방수시트(50)의 상면에 열접합시킨다. 이와 같이 본 고안은 부직포(10), 벤토나이트(20), 직포(30)를 적층시킨 것에 방수막(40)을 추가로 적층시킨 것으로 시공이 편리하여 공기를 단축시킬 수 있다. 또한, 부직포(10)와 직물(30)의 물을 유도하는 성질과 벤토나이트(20)의 방수효과에 방수막(40)의 방수효과를 더함으로써 거의 완벽한 방수효과를 얻을 수 있다.At the time of waterproof construction using the present invention as described above, the waterproof sheet 50 according to the present invention is fixed to the shotcrete surface 1 placed on the tunnel excavation surface with a fixing nail 7. In this case, the ends of the nonwoven fabric 10, the bentonite 20, and the woven fabric 30 of the adjacent waterproof sheet 50 are in contact with each other, and the connection ends are positioned on the upper surface of the adjacent waterproof sheet. Then, the connection end 42 of the waterproof sheet 50 is thermally bonded to the upper surface of the waterproof sheet 50 to be adjacently disposed. As described above, the present invention is a laminate of the nonwoven fabric 10, the bentonite 20, and the woven fabric 30 in addition to the waterproof membrane 40, which is convenient in construction and shortens the air. In addition, by adding the waterproof effect of the waterproof membrane 40 to the water-inducing property of the nonwoven fabric 10 and the fabric 30 and the waterproof effect of the bentonite 20 can be almost completely waterproof.
이상에서와 같이 본 고안에 의하면, 부직포, 벤토나이트, 직포, 방수막을 적층시켜 단품화하여 제공함으로써, 시공이 편리할 뿐만 아니라 부직포와 직포의 물을 유도하는 성질과 벤토나이트의 방수효과에 방수막의 방수효과를 더함으로써 거의 완벽한 배수 효과를 얻을 수 있다. 특히 돌출연결부(42)에 의해 방수시트(50)의 연결부위가 커버되므로 방수시트의 연결부위를 통해 누수될 우려가 없다. 또한, 본 고안에 의한 방수시트는 비교적 두께가 두껍기 때문에 방수시공시나 후속공정에서 방수시트가 파손될 우려가 없다.As described above, according to the present invention, by providing a non-woven fabric, bentonite, woven fabric, and waterproof film by laminating separately, the construction is not only convenient, but also the property of inducing water of the nonwoven fabric and woven fabric, and the waterproof effect of the waterproof film on the waterproof effect of bentonite. By adding, almost perfect drainage effect can be obtained. In particular, since the connecting portion of the waterproof sheet 50 is covered by the protruding connecting portion 42, there is no fear of leakage through the connecting portion of the waterproof sheet. In addition, since the waterproof sheet according to the present invention is relatively thick, there is no fear that the waterproof sheet will be damaged during waterproof construction or in a subsequent process.
