Bridge expansion joint structure and construction method
The invention discloses a bridge expansion joint structure and a construction method thereof. The bridge expansion joint structure comprises an expansion joint base material and an expansion joint sealant material. The expansion joint base material comprises fast setting concrete base layers and polyurethane elastic concrete pavements, wherein the fast setting concrete base layers are poured on the two sides of a reserved notch of each expansion joint, the fracture surfaces of the fast setting concrete base layers on the two sides comprise concave structures, the polyurethane elastic concrete pavements are poured on the fast setting concrete base layers, and the fracture surfaces of the polyurethane elastic concrete pavements on the two sides comprise convex structures and are connected with the fast setting concrete base layers on the two sides in a matched mode respectively. The expansion joint sealant material comprises a sealant bottom die arranged between the expansion joints, and a sealant injected into the sealant bottom die between the expansion joints to seal the expansion joints.
