[0002] When building a bridge, it is necessary to set an expansion joint at the upper end of the bridge. An expansion joint refers to a structural joint set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion and contraction). Expansion joint sealing is a weak link in cement concrete road pavements and railway concrete bases. In the past, cast-in sealants or expansion joint strips have been used for sealing for a long time.

[0003] Most traditional expansion joint rubber strips are provided with multiple waterproof slots on both sides, and then connected to the two sides of the expansion joint through the multiple slots.
