Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bridge slab base technology, and in particular relates to a prefabricated bridge slab base with a reinforcement structure. Background Technology
[0002] A bridge is generally a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. A bridge generally 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. Ancillary structures refer to bridge approach slabs, tapered slopes, revetments, and diversion works, etc.
