[0023] In this embodiment: first, the steel plate gasket 1 and the bottom rubber sheet 2 are laid on the roadbed and socketed with the fixing mechanism, and then the shielding rubber sheet 3 is covered on the top of the bottom rubber sheet 2 and socketed with the fixing mechanism, and then the fixing mechanism is locked, and the steel plate gasket 1, the bottom rubber sheet 2 and the shielding rubber sheet 3 are pressed tightly. After pressing, the protective rubber sheet 5 is connected to the receiving groove 6 through the rubber vertical plate 7 and the rubber horizontal plate 8, and slides. During the sliding process, the protective rubber sheet 5 protects the top of the fixing mechanism to prevent the fixing mechanism from direct contact with rainwater.
