Abstract
Description
Technical Field

[0002] A bridge is generally composed of several major parts such as the bridge deck, bridge structure and traffic engineering facilities. The flatness of the bridge deck refers to the deviation value of the longitudinal convexity of the bridge surface. The flatness of the bridge deck is an important indicator in bridge deck evaluation and bridge deck construction acceptance. It mainly reflects the flatness of the longitudinal section profile curve of the bridge deck. When the longitudinal section profile curve of the bridge deck is relatively smooth, it means that the bridge deck is relatively flat, or the flatness is relatively good. Otherwise, it means that the flatness is relatively poor. A good bridge deck requires good flatness. After the bridge construction is completed, the bridge deck needs to be tested for levelness to ensure the normal passage of vehicles and pedestrians.

The existing bridge engineering bridge deck level detection device has a relatively simple structure, cannot adjust its own length according to the width of the bridge, and cannot accurately measure the levelness of the bridge deck, which affects the work efficiency. For this reason, we propose a bridge engineering bridge deck level detection device. Utility Model Content
