[0025] The present invention will be further described in detail below in conjunction with the drawings:
[0026] Such as figure 1 As shown, the composite multi-layer explosion-proof device for viaduct piers of the present invention includes a polymer elastic body 3, a circular steel pipe 5 and an empty cabin.
[0027] The polymer elastomer 3, the circular steel pipe 5 and the empty cabin are arranged on the outside of the bridge pier 1 from the inside to the outside. Among them, the polymer elastomer 3 is glued to the pier 1 and the steel plate 4, and the round steel pipe 5 is welded to the empty cabin. , The empty cabin is composed of an inner steel plate 6 and an outer steel plate 8.
[0028] The surface of the bridge pier 1 is evenly coated with waterproof adhesive after being polished and rough, and the polymer elastomer 3 is glued to the surface of the bridge pier 1. There should be no air bubbles between the polymer elastomer 3 and the bridge pier 1. The surface of the polyme...
