摘要： A method for providing a drainage from a space between a lined concrete wall and a lining for protecting the lined concrete wall, wherein the method comprises the steps of arranging one or more draining member(s) each comprising a draining pipe having a blind flange arranged at both ends and having a length including the blind flanges that is substantially equal to the wall thickness in a casting frame so that the blind flanges are resting at the casting frame at the inside of the wall and the outside of the wall, respectively; filling concrete filled into the casting frame to cover the draining member(s) and allowing the concrete is allowed to cure; removing the casting frame from at least one of the sides of the concrete wall and; drilling through the blind flanges to open the draining member(s). A drained concrete wall and a concrete vessel are also described.
