[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are built to cross mountain streams, adverse geological conditions, or to meet other transportation needs to make passage more convenient. A bridge is generally composed of a superstructure, a substructure, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles. The substructure includes abutments, piers, and foundations. The supports are force-transmitting devices installed at the supporting locations of the span structure and the piers or abutments. The ancillary structures Creation refers to the bridge head tread, tapered slope protection, bank protection, diversion project, etc. Bridge expansion joints will be used in the process of bridge construction. Bridge expansion joints: refers to the expansion joints usually set between the two beam ends, between the beam ends and the abutments, or at the hinged position of the bridge to meet the requirements of bridge deck deformation; the expansion joints are required to be able to freely expand and contract in two directions parallel and perpendicular to the axis of the bridge, and be firm and reliable. When vehicles pass by, it should be smooth, without sudden jumps and noise; it must be able to prevent rainwater and garbage and soil from seeping in and blocking; installation, inspection, maintenance, and removal of dirt must be simple and convenient.
