The pull plate 703 is installed at the top end of the pull pin 704. The dampers 706 are installed on both sides of the bottom inner side of the fixing frame 7. The bottom end of the damper 706 is connected to the top end of the positioning plate 705. Four fixing frames 7 are arranged on the outside of the polyester fiber layer 1, the thermal insulation layer 2, and the geotextile layer 3, and the four fixing frames 7 are symmetrically distributed. When in use, remove the fixing frame 7 and place it on the outside of the polyester fiber layer 1, the thermal insulation layer 2, and the geotextile layer 3. Then pull the pull plate 703 upwards, and use the pull pin 704 to drive the positioning plate 705 upwards. Then place the polyester fiber layer 1, the thermal insulation layer 2, and the geotextile layer 3 inside the fixing frame 7. Release the pull plate 703. At this time, the telescopic spring 701 is subjected to elastic force, and with the cooperation of the damper 706, it drives the positioning plate 705 to extend.
