GROUNDWATER OR SEDIMENT SPILL PREVENTION DEVICE FOR TUNNEL EXCAVATION
The present invention relates to a device to prevent an outflow of underground water or soil for a tunnel excavation and, more specifically, relates to a device to prevent an outflow of underground water or soil for tunnel excavation capable of preventing a land subsidence phenomenon caused by the outflow of underground water or soil through a gap between a tunneling machine of a discharge unit and a tunnel when excavating the tunnel using the tunneling machine. According to the present invention, the device to prevent the outflow of the underground water or soil for tunnel excavation comprises: a coupling adapter buried in an inner wall of the discharge unit of a vertical tunnel, having a coupling flange on a front end, and formed into a hollow reinforcing body (12) to enable the tunneling machine to penetrate through; and an outflow preventing member coupled to the coupling adapter, preventing a gap between the tunnel and the tunneling machine by applying a water pressure to the discharge unit.
본 발명은 터널굴착용 지하수 또는 토사유출방지장치에 관한 것으로, 더욱 상세하게는 터널굴진기에 의한 터널굴삭시 도출부의 터널굴진기와 터널 사이 틈새로 지하수나 토사가 유출되어 지반이 침하되는 현상을 방지하도록 하는 터널굴착용 지하수 또는 토사유출방지장치에 관한 것이다. 이와 같은 본 발명에 따른 터널굴착용 지하수 또는 토사유출방지장치는 수직갱의 도출부 내벽에 매설되며, 선단부에 결합플랜지가 형성되며, 터널굴진기가 관통되도록 내부가 중공된 매설보강체(12)로 형성된 체결어댑터; 체결어댑터에 결합되어 도출부 부위에 수압을 형성하여 터널과 터널굴진기 사이 틈새를 차단하기 위한 유출방지부재를 포함하는 것을 특징으로 한다.
