Description

Technical Field

[0001] This utility model relates to the field of bridge reinforcement technology, and more specifically, to a prefabricated bridge reinforcement structure. Background Technology

[0002] Bridges generally refer to structures erected over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also been extended to refer to structures built across mountains, streams, adverse geological conditions, or to meet other transportation needs, making travel more convenient. A bridge typically consists of a superstructure, substructure, supports, and ancillary structures. The superstructure, also known as the bridge span structure, is the main structure that crosses obstacles; the substructure includes abutments, piers, and foundations; supports are force-transmitting devices installed at the support points between the bridge span structure and the piers or abutments; and ancillary structures include approach slabs, tapered slopes, revetments, and diversion works. Currently, bridge beams are generally supported by two piers, with the middle of the beam suspended in the air, affecting the bridge's strength and stability. Therefore, we propose a prefabricated bridge reinforcement structure. Utility Model Content
