PURPOSE:To reduce the cost by providing a guide vane ring fixing flange while forming the circumferential face near to a funnel type outside casing where a stay vane is penetrating through the side wall and the circumference of the stay vane with steel plate and forming other circumferential face with base concrete. CONSTITUTION:The side wall 13 of a water guide path is formed of a stay vane circumference 20a, a circumference 20b near to a guide vane ring fixing flange and base concrete sections 21, 21a. The stay vane circumference 20a will surround a stay vane 17 extending vertically from an inside casing 12 and made of steel plate. The circumference 20b is equipped with a guide vane ring fixing flange 15 at the downstream side end face and made of steel plate. The circumferential face except those 20a, 24b is formed of base concrete sections 21, 21a. |
