Description

Sealing Gasket {Sealing Gasket}

본 발명은 터널 외부로부터 터널벽을 통해 터널 내부로 물이 침입하는 것을 방지하는 지수 가스켓에 관한 것이다.The present invention relates to a water stop gasket that prevents water from entering the tunnel from outside the tunnel through the tunnel wall.

초장대의 터널 공사에 이용되는 공법은 크게, 발파 공법과 기계식 공법이 있다. 발파 공법의 대표적인 공법은 NATM(New Austrian Tunneling Method) 공법이 있으며, 기계식 공법의 대표적인 공법은 TBM(Tunnel Boring Machine) 공법이 있다.The construction methods used in the construction of super long tunnels are largely divided into blasting methods and mechanical methods. The representative method of the blasting method is the NATM (New Austrian Tunneling Method) method, and the representative method of the mechanical method is the TBM (Tunnel Boring Machine) method.

TBM 공법은 TBM 기계로 굴착 작업을 진행해 나가며 그 후방에서 미리 만들어진 콘크리트 세그먼트(이하 간단히 '세그먼트'라 함)를 조립하여 터널벽을 형성하는 공법이다.The TBM method is a method of forming a tunnel wall by assembling pre-made concrete segments (hereinafter simply referred to as 'segments') at the rear while excavating with a TBM machine.

이러한 TBM 공법은 수분이 많이 함유된 연약 지반 등의 터널 공사에 적합하기 때문에, 특히, 해저터널 공사에 많이 이용되고 있다. Since this TBM method is suitable for tunnel construction such as soft ground containing a lot of moisture, it is particularly widely used for undersea tunnel construction.

TBM 공법은, 최근 고가 장비이던 TBM 기계의 가격이 큰 폭으로 감소하였으며, 발파 작업을 필요로 하지 않기 때문에 소음이 적어서 도심지 터널 공사 등에 적합하여 최근 그 이용이 더욱 증가하고 있다.The TBM method has recently significantly reduced the price of TBM machines, which were expensive equipment, and since it does not require blasting, it has low noise and is suitable for urban tunnel construction, and its use is increasing.

종래의 가스켓은 세그먼트 외주에 지수 가스켓을 둘러싸면서 고정하는 방식을 사용하였다. 세그먼트는 4개의 모서리가 형성되어 있는데 가스켓이 모서리에 덜러지는 과정에서 심하게 절곡이 되고 고무 소재인 가스켓은 찢어지는 등의 문제가 있어 이를 해결하기위한 방안이 필요한 실정이다.Conventional gaskets used a method of fixing the index gasket while surrounding the outer periphery of the segment. The segment has four corners, but there are problems such as severe bending in the process of the gasket falling off the corners and tearing of the gasket made of rubber.

상기의 배경기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.The matters described as the background art above are only for improving the understanding of the background of the present invention, and should not be accepted as acknowledging that they correspond to the prior art already known to those of ordinary skill in the art.
