It includes a truss, a first steel section and an outer shell. The truss is provided with multiple circles of first steel sections in parallel in the length direction, and the first steel sections are connected to the outer shell. Each circle of the first steel section is incompletely elliptical and includes multiple arc beams. Adjacent arc beams are connected, and multiple arc beams are distributed on both sides of the truss in the width direction and above the truss.
