The push plate 26 pushes the wire rope 12 to move. The movement causes the right-angle sealing block 14 located at the bottom to open at an angle. Then, it is wound up by the first winding device 11 and unwound by the second winding device 15. At this time, the wire rope 12 moves the strip sealing block 13 and the right-angle sealing block 14 through the positioning block until the positioning block moves to the bottom of the expansion joint. Then, the other end of the wire rope 12 on the second winding device 15 is untied, and then the wire rope 12 is wound up by the first winding device 11 until the winding is completed.
