지하구조물의 외방수용 겹침이음 설치형 보호방수시트 및 이를 이용한 지하구조물의 외방수공법{Waterproof Sheet with Protective Material for Exterior-Waterproof of Underground Structure and Exterior-Waterproofing Method Using the Same}Water-proof Sheet with Protective Material for Exterior-Waterproof of Underground Structure and Exterior-Waterproofing Method Using the Same}

본 발명은 지하구조물의 외방수에 관한 것으로, 더욱 상세하게는 토압 등 지하환경으로부터 효과적으로 보호하면서 쉽게 겹침이음을 실현할 수 있는 지하구조물의 외방수용 겹침이음 설치형 보호방수시트와, 이러한 보호방수시트를 바람직하게 이용한 지하구조물의 외방수공법에 관한 것이다.The present invention relates to the waterproofing of the underground structure, and more particularly to the waterproofing of the overlapping installation type of waterproofing for the waterproofing of the underground structure, which can easily realize the overlapping joint while effectively protecting from the underground environment such as earth pressure. It relates to the external waterproofing method of underground structures.

건물의 지하부분, 터널, 지하공동구, 트렌치 등 콘크리트 지하구조물은 지하수의 침투로부터 보호하기 위해 콘크리트 지하구조물의 외측 표면에 방수공사를 실시하며, 이를 외방수라 한다. 일반적으로 지하구조물의 외방수는 지하구조물의 외측 표면에 방수재를 시공한 후(도 1(a)) 방수층 보호를 위해 2cm 이상의 PE 발포재를 부착 시공하며(도 (1b)), 이렇게 방수공사가 끝난 후에는 되메우기 공사를 한다(도 1(c)). 그러나, 이와 같이 방수재와 보호재를 구분하여 단계적으로 시공하는 것은 작업량이 많아지고 시공품질 확보가 어렵다는 단점이 있다. 이러한 단점을 개선하고자 방수재와 보호재가 결합된 복합방수시트가 개발된 바 있으며, 대표적으로 특허 제10-0796019호가 있다.Concrete underground structures such as underground sections of tunnels, tunnels, underground cavities, trenches, etc. are waterproofed on the outer surface of the concrete underground structures to protect them from infiltration of groundwater. In general, the external water of the underground structure is constructed by attaching a PE foam of 2 cm or more to protect the waterproof layer after the waterproofing material is installed on the outer surface of the underground structure (Fig. 1 (a)). After the end, the backfill construction is performed (Fig. 1 (c)). However, the step-by-step construction by separating the waterproofing material and the protective material in this way has a disadvantage in that the amount of work is increased and the construction quality is difficult. In order to improve these disadvantages, a composite waterproof sheet having a combination of a waterproofing material and a protective material has been developed, and typically there is a patent No. 10-0796019.

특허 제10-0796019호는 이형지층, 방수층(합성고무층+합성고무표면보호층), 방수보호층(제1,2방수층+박리유도층)의 적층구조로 이루어진 자착식 복합방수시트에 관한 것으로, 토압이나 지반침하 등 외력이 작용할 때 박리유도층에 의해 방수보호층의 부분적인 박리를 유도함으로써 남아있는 방수보호층으로 방수층을 보호하고자 하는 방식이다. 특허 제10-0796019호는 방수층에 방수보호층보다 돌출된 날개형태의 이음부를 통해 별도의 테이프 작업없이 연결 설치하고 있는데, 이에 따라 방수층은 겹침이음되고, 방수보호층은 맞대어 설치된다. 이러한 설치에서 방수보호층은 맞대어 설치되어야 하기 때문에 정교한 설치작업이 요구되어 작업성이 떨어지며, 또한 방수보호층 사이의 연결 작업이 따로 없어 방수보호층 사이에는 틈새가 생기기 쉽고 그 사이 틈새를 통해 토사나 지하수가 유입되면서 방수층에 직접적으로 작용할 우려가 있다.Patent No. 10-0796019 relates to a self-supporting composite waterproof sheet composed of a laminated structure of a release layer, a waterproof layer (synthetic rubber layer + synthetic rubber surface protective layer), a waterproof protective layer (first, second waterproof layer + peeling induction layer), It is a way to protect the waterproof layer with the remaining waterproof protective layer by inducing partial peeling of the waterproof protective layer by the peeling induction layer when an external force such as earth pressure or ground subsidence is applied. Patent No. 10-0796019 is installed in the waterproof layer through the joint of the wing shape protruding than the waterproof protective layer without a separate tape work, accordingly, the waterproof layer is overlapped, the waterproof protective layer is installed facing each other. In this installation, the waterproof protective layer must be installed face to face, requiring sophisticated installation work and inferior in workability. In addition, there is no connection between the waterproof protective layers, so that there is a gap between the waterproof protective layers, As groundwater flows in, there is a concern that it directly acts on the waterproofing layer.

It can be processed to form two lines. Two lines of cutout line (L) are for separating and removing the release layer (111), the section in which the release layer (111) is left by removing the release layer (111), leaving only the section between the two lines of cut line (L). It can be used as the air pocket forming section, it will be described in Figure 7 (c). In addition, two lines of cut line (L) also serves to guide the joint position in the overlapping process.

도 6과 도 7은 본 발명에 따른 지하구조물의 외방수공법의 시공상태도이다. 보는 바와 같이 먼저 지하구조물(C)의 외측 표면에 보호방수시트(100)를 부착 설치하며, 필요에 따라 프라이머(P)를 도포한 후 그 위에 부착 설치할 수 있다. 도 6에는 지하구조물(C)로 공동구를 예시하고 있다. 이때 보호방수시트(100) 상호 간의 이음부는 보호시트의 분리형 날개부(121)를 방수시트(110)에서 분리하여 들어올린 상태에서 방수시트(110)를 겹치게 배치하여 부착한 후 들어올린 보호시트의 분리형 날개부(121)를 내려 겹치게 배치하면서 설치한다(도 7(a)). 특히 도 3과 같이 보호시트의 분리형 날개부(121)가 양단부에 형성된 보호방수시트(100)라면 겹침이음부에서 들어올려진 분리형 날개부(121)끼리도 서로 포개면서 설치할 수 있으며(도 7(b)), 이 경우 분리형 날개부(121)의 들어올려진 높이를 최소화하면서 방수시트(110)와 보호시트(120) 상호 간을 효과적으로 포갤 수 있다.Figure 6 and Figure 7 is a state diagram of the construction of the external structure of the underground structure according to the present invention. As you can see first install the protective waterproof sheet 100 on the outer surface of the underground structure (C), and if necessary, after applying the primer (P) can be attached to the installation. 6 illustrates the cavity as an underground structure (C). In this case, the joints between the protective waterproof sheets 100 are separated by lifting the detachable wing 121 of the protective sheet from the waterproof sheet 110, and are then attached to each other by placing the waterproof sheet 110 in an overlapping manner. The detachable wing 121 is installed while being laid down (Fig. 7 (a)). In particular, if the separate wing 121 of the protective sheet is a protective waterproof sheet 100 formed on both ends as shown in Figure 3 can also be installed while overlapping the separate wing 121 is lifted from the overlapping joint (Fig. 7 (b)) In this case, while minimizing the lifted height of the detachable wing 121 can be effectively nested between the waterproof sheet 110 and the protective sheet 120.

도 5와 같이 2줄의 절취선(L)이 형성된 이형지층(111) 구비한 보호방수시트(100)를 이용하는 경우에는 지하구조물(C)의 외측 표면에 2줄의 절취선(L) 사이 구간만을 제외하고 이형지층(111)을 제거하면서 보호방수시트(100)를 부착 설치한다(도 7(c)). 이때 보호방수시트(100) 상호 간의 이음부는 보호시트의 분리형 날개부(121)를 방수시트(110)에서 분리하여 들어올린 상태에서 남겨둔 이형지층(111) 내측에서부터 방수시트(110)를 겹치게 배치하여 부착한 후 들어올린 보호시트의 분리형 날개부(121)를 내려 겹치게 배치하여 설치한다. 보호방수시트(100)는 남겨둔 이형지층(111)에 의해 자연스럽게 부착구간 사이에 비부착구간이 형성되면서 부착 설치된다. 이어 남겨둔 이형지층(111)이 위치한 비부착구간에 공기주입구를 형성하면서 밀폐하며, 이로써 이형지층(111)이 남겨진 비부착구간은 에어포켓으로 형성된다. 마지막으로 공기주입구를 통해 공기를 주입하면서 공기누출여부를 확인한다. 남겨둔 이형지층(111)을 사이에 두고 완전히 부착되었다면 공기를 주입하여 일정 압력에 도달하면 더 이상의 공기 주입이 되지 않으나, 완전한 부착이 이루어지지 않았다면 공기를 주입하더라도 일정 압력에 도달하지 못한 채 공기가 지속적으로 주입되므로 공기누출이 이루어지는 것으로 볼 수 있다. 공기누출로 보는 경우에는 보호방수시트(100)를 재시공한다.When using a protective waterproof sheet 100 having a release line layer 111 formed with two lines of cut lines L as shown in FIG. 5, only a section between two lines of cut lines L is disposed on the outer surface of the underground structure C. And while attaching the protective waterproof sheet 100 while removing the release paper layer 111 (Fig. 7 (c)). In this case, the joints between the protective waterproof sheets 100 are disposed to overlap the waterproof sheet 110 from the inside of the release paper layer 111 that is left in the lifted-up state in which the detachable wing 121 of the protective sheet is separated from the waterproof sheet 110. After attaching, the detachable wing 121 of the lifted protective sheet is placed down and overlapped. The protective waterproof sheet 100 is naturally attached to the non-sticking section between the attaching sections by the remaining release layer 111. Subsequently, an air inlet is formed in the non-attachment section in which the release layer 111 is left, and is sealed, whereby the non-attachment section in which the release layer 111 is left is formed of an air pocket. Finally, check for air leakage while injecting air through the air inlet. If the remaining release layer 111 is completely attached, the air is injected until it reaches a certain pressure and no more air is injected, but if it is not completely attached, the air does not reach a certain pressure even if the air is injected. Since it is injected into the air can be seen to be made. In the case of air leakage, the protective waterproof sheet 100 is reconstructed.

보호방수시트(100)의 부착이 끝난 후에는 보호방수시트(100) 주변으로 되메우기를 하게 되는데, 분리형 날개부(121)는 따로 부착하지 않더라도 토압에 의해 밀착된다. After the attachment of the protective waterproof sheet 100 is to be backfilled around the protective waterproof sheet 100, the detachable wing 121 is in close contact by the earth pressure even if not separately attached.
