The saddle 3 is arranged at the bottom of the shell 1 and is used for supporting the shell 1. The saddle 3 is arranged in a position corresponding to the support assembly, i.e. the saddle 3 has a plurality of seats and is arranged corresponding to the sliding support assembly 4 and the fixed support assembly 5, respectively. Considering the conventional double saddle design, the distance between two saddles is larger, a larger axial bending moment exists in the middle of the inner shell, and the problem that local stress check does not pass sometimes occurs, and the problem is solved by increasing the thickness of the inner shell in the conventional design, so that the manufacturing cost is increased. To reduce the manufacturing cost, the utility model can adopt a three saddle design as shown in fig. 1, namely, a saddle 3 and a corresponding sliding support component 4 are added in the middle of a conventional double saddle, and the cost of the materials such as the support component, the saddle and the civil engineering added by the structure is obviously lower than the cost of the thickness thickening of the inner shell, which is a relatively preferable choice.
