The method of producing a water conduit through a barrier structure, in particular consisting of concrete or masonrywork, under water pressure provides that, from the tailwater side or airside, a gallery (20) is set up through the barrier structure (1) as far as a safeguard distance (s) with respect to the wall on the headwater side of the barrier structure. A cover (15), as seal, is fitted in a sealing manner at the imaginary opening, which forms the water inlet, of the gallery (20), on the wall on the headwater side of the barrier structure (1), before reaching, or upon reaching, the safeguard distance (s), the cover sealing, by means of its border region, with respect to the wall of the barrier structure (1). Thereafter, the gallery (20) can be produced further as far as the cover (15). The cover (15) is removed again from the water inlet in order that the water can be channelled in. <IMAGE> |
