一、斜柱环梁式机墩的提出立式水轮发电机的机墩,在结构形式上一般分为圆筒式、直柱环梁式、构架式三种。但是,当蜗壳平面尺寸比机组机架平面尺寸大而又采用金属蜗壳时,为使机墩柱不压在只能承受内水压力的金属蜗壳上, First, the inclined column beam beam machine pier proposed vertical turbine generator piers, in the general form of the structure is divided into cylindrical, straight column ring beam, frame type three. However, when the volute plane size is larger than the plane size of the unit frame and the metal volute is used, in order to prevent the pier from being pressed against the metal volute which can only withstand the internal water pressure,
