일반적으로 흙막이는 지하공사를 안전하고 원활하게 할 수 있도록 굴토벽면의 붕괴된 토사의 유입을 방지하기 위하여 설치되는 가설구조물이기 때문에 안정성과 시공성은 물론 경제성도 동시에 요구된다.In general, the earthquake block is a temporary structure installed to prevent the inflow of collapsed soil on the oyster wall so that the underground construction can be safely and smoothly. Therefore, stability, constructability, and economic efficiency are required at the same time.

종래의 흙막이 공법으로는 파낸 흙에 고화제를 혼합하는 타설하는 공법과, 숏크리트를 이용하는 공법, 폴리머 몰탈 스프레이 공법, 버림 콘크리트를 타설하는 방법, 조적을 쌓는 방법 및 약액주입공법 등의 다양한 공법이 있다.Conventional earth clogging methods include a variety of methods, such as the method of pouring the solidified to the excavated soil, the method using the shotcrete, the polymer mortar spray method, the method of casting the discarded concrete, the method of stacking the masonry and the chemical injection method .

이러한 공법 들은 설계자가 가설구조(흙막이벽)를 설계함에 있어서 토질 및 지반의 형태, 지하수위, 매설심도, 관로 및 구조물의 매설폭(굴토폭), 경제성 및 시공성, 현장주위 여건 등을 고려하여 채택해야 한다.These methods are adopted by the designer in consideration of the shape of the soil and the ground, groundwater level, depth of burial, pipe width and laying width of the pipeline and structure, economic feasibility and constructability, and site conditions. Should be.

이와 같은 흙막이 공사를 시행한 다음, 방수층을 시공하기 위해 합판을 대거나, 흙막이 공사한 부분에 바로 시공하게 되는데 이때 사용되는 방수층은 대부분이 방수시트로 시공한다. After the earthquake construction, such as plywood to install the waterproofing layer, or the construction of the construction of the earthquake immediately to the construction part, the waterproofing layer is mostly used as a waterproof sheet.

이와 같이 방수시트를 이용하여 방수층을 선(先) 시공한 후에, 후속공정으로 철근배근, 거푸집조립 등을 실시 할 때 방수층인 방수시트가 찢김, 파단 등의 손상될 우려가 있었으며, 콘크리트를 타설하는 경우에도 콘크리트가 양생되고 나서 방수층인 방수시트와 콘크리트가 접착되어 있지 않기 때문에 누수의 확산을 방지할 수가 없다.In this way, after pre-installing the waterproofing layer using the waterproofing sheet, the waterproofing sheet, which is the waterproofing layer, may be damaged, such as tearing or breaking, when reinforcing reinforcement and formwork as a subsequent process. Even if the concrete is cured, the waterproof sheet, which is the waterproof layer, is not bonded to the concrete, and thus, the diffusion of the leak cannot be prevented.
