Zusammenfassung:The present disclosure provides a fireproof structure of a tube joint of an immersed tube tunnel with a linear moving mechanism including a waterproof tape assembly (10) and a fireproof assembly (30) both connected between adjacent first and second tubes (40, 50). The fireproof assembly (30) includes a protection plate assembly (31) including a first fireproof plate assembly (311), a second fireproof plate assembly (313) spaced from the first fireproof plate assembly (311), and a heat insulation piece (312) fixedly connected between the first fireproof plate assembly (311) and the second fireproof plate assembly (313); a movable connection assembly (33), the first fireproof plate assembly (311) and second fireproof plate assembly (313) being movably connected to the second tube (50) through the movable connection assembly (33); and a flexible fireproof belt (35) between the first fireproof plate assembly (311) and the second fireproof plate assembly (313), one end of the flexible fireproof belt (35) being connected with the heat insulation piece (312), and the other end being connected with the second tube (50).
