Description

Technical Field

[0001] The utility model relates to the technical field of bridge expansion joint structures, in particular to a bridge expansion joint structure with a drainage device. Background Art

[0002] A building expansion joint, also known as a construction joint, is a structural joint installed at appropriate locations along the construction joint of a building or structure to prevent cracks or damage due to temperature fluctuations (thermal expansion and contraction). Expansion joints separate building components above the foundation, such as walls, floors, and roofs (except wooden roofs), into two independent sections, allowing the building or structure to expand and contract horizontally along its length.

[0003] During bridge construction, a blind drainage ditch is usually set in the transverse direction of the bridge in the bridge deck pavement layer at the bottom of the asphalt surface layer near the expansion joint. However, the asphalt surface layer is soft in texture and can easily cause clogging of the blind drainage ditch under repeated impact by vehicles, resulting in poor drainage. Moreover, the blind drainage ditch is constructed earlier than the expansion joint of the bridge. In order to prevent the blind drainage ditch from being damaged by cutting the bridge deck pavement layer during the later construction of the expansion joint, the blind drainage ditch is often set at a certain distance from the expansion joint concrete, resulting in some accumulated water remaining at the junction of the asphalt surface layer and the expansion joint concrete and unable to be discharged.
