Abstract
Description
Technical Field
[0001] The present application relates to the field of deflection detection, and in particular to a deflection detection device for a bridge steel structure. Background Art
[0002] Bridges generally refer to structures erected 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 erected to cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. Bridges are generally composed of superstructures, substructures, 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 transmission devices installed at the supporting locations of the span structure and piers or abutments; and the ancillary structures refer to the bridgehead slabs, conical slope protection, revetments, diversion projects, etc.
[0003] Bridge deflection is a very important parameter for bridge structures. It directly reflects the vertical overall stiffness of the bridge structure and is an important basis for reflecting the linear changes of the bridge. Bridge deflection is closely related to the bridge's bearing capacity and its ability to withstand dynamic loads such as earthquakes. Scientific testing methods are not only of great significance for the testing of bridge bearing capacity and bridge earthquake prevention and disaster reduction, but also can accumulate time and experience for improving bridge design theory and construction technology.
[0004] At present, the deflection detection of existing bridge steel structures can generally be measured by a deflection detector. However, due to the long inspection cycle of bridges, which is generally once every three years, moss and dirt will inevitably form on the bottom of the bridge during this period. At this time, the deflection detection using a deflection detector will easily be affected by the moss and dirt, resulting in inaccurate test results. Utility Model Content
