(A groove-shaped stepped portion is constructed, and a seal/sliding material is fitted to the irregularly shaped step to form a headrace that is isolated from the inside of the tunnel. There is no chance of water leaking into the tunnel as it is flushed away from the tunnel.Furthermore, since the headrace is separated from the inside of the tunnel by an insulating seal strip, leakage water will not freeze inside the headrace. It flows down along the V-shaped water guide groove of the seal strip material.Furthermore, according to the construction method of the present invention, part or all of the both sides of the seal strip material are constituted by water-expandable elastic segment seals. It follows the expansion and contraction caused by tunnel concrete contraction and atmospheric temperature changes, and has a feature that provides a reliable sealing effect for a long time.In addition, according to the present invention, the sealing band iM material was constructed at the joint for concrete pouring on the inner wall of the tunnel.
Since it is a simple construction method of inserting and gluing into the mold step B1,
It requires almost no construction time and labor and is highly effective.
