Abstract

PURPOSE: To cancel growth of abnormally high stress by reducing elongation of an embedded piping in unit length relative to displacement of embedded piping connection for a hydraulic turbine casing, etc. due to hydraulic pressure, etc.
CONSTITUTION: Piping 4 is connected to an pressure intake 2 of a casing 1 embedded in a building concrete 5 through a joint 3 and a portion l of the piping which does not contact the concrete 5 is covered with a sleeve 6. Also, the sleeve 6 is filled with a buffer member 7 so that away of the piping can not be enlarged by vibration of apparatus. Thus, the piping 4 can have an unfixed portion of proper length l which can be expanded and contracted relative to the expansible amount of the piping 4 due to fluctuation of the casing 1.
